ADVERTISEMENT. 



The present volume comprises two separate installments of a compre- 

 hensive work designed by the author to embrace a systematic synoptical 

 review of the entire Flora of the North American Continent. Nearly 

 forty years ago such a work, undertaken by the joint labors of our 

 two eminent botanists, Professors Torrey and Gray, was arrested by 

 the pressure of other duties, with the execution of the Polypetalous 

 division of the DICOTYLEDONS, the first class of the great PH^ENOGA- 

 MOUS series, and five orders of the Gamopetalse, including the great 

 order of the Compositse. This comprises just the scope of the projected 

 first volume of the present series. 



Assuming that the reconstruction of the first division the Polypetalse 

 would occupy some 500 pages, to constitute the 1st part of Vol. I, this 

 present 2d part of the volume is made to commence with the Gamo- 

 petalse, the full exposition of which second division extends through the 

 1st part of Vol. II. The 2d part of Vol. II will probably be occupied 

 with the third division of the DICOTYLEDONS the Apetalse ; and Vol. 

 Ill is designed to take up the MONOCOTYLEDONS. 



The present publication, therefore, though made up of two consecutive 

 parts of different volumes of the work, may be said to be complete in 

 itself in giving a complete view of the entire division of the Gamopetalse. 



The preparation of the work has been largely aided by the funds of 



the Smithsonian Institution.

NOTICE. 



EXPERIENCE having shown that some years must elapse before this work 

 can be completed, and a new impression of the part first published (in 

 1878) being called for, it is expedient now to issue the two parts, which 

 together comprise all the Gamopetalous Dicotyledons, in the form of a 

 single volume, under the auspices of the Smithsonian Institution. 



Both parts have been corrected, as far as could well be done upon 

 the electrotype plates ; a supplement of eleven pages is added to the very 

 recently published Volume I. Part II., and its full index has been made 

 anew. The tabular enumeration of the contained genera and species has 

 been transferred to the end of the Gamopetala3. To Volume II. Part L, a 

 supplement of seventy pages is added, and a few pages have been recast ; a 

 tabular enumeration of all the gamopetalous genera and species is appended, 

 and a complete index of genera, species, synonyms, &c., making an 

 extension from 402 to about 500 pages.

ORDER LXX. RUBIACE^. 



Herbaceous or woody plants ; with opposite entire and stipulate leaves, vary- 

 ing to verticillate, or in the Stellatce the leaves in whorls without stipules (unless 

 accessory leaves be counted as such) ; mostly hermaphrodite regular flowers, 

 either o-nierous or 4-merous ; calyx-tube adnate to the ovary ; and stamens as 

 many as and alternate with the lobes of the corolla, inserted on its tube or 

 throat. Style single, sometimes with 2 or more lobes or stigmas. Fruit various : 

 seeds in our genera albuminous. 



Of this vast and largely tropical order 2G of the 140 recognized genera come 

 within our limits, but more than half of them only in subtropical Florida. They 

 rank under 14 of the 25 recognized tribes, too large a scaffolding for a frag- 

 mentary structure. So they are here disposed under three series ; of which the 

 third is only a special modification in foliage of the second.

ORDER LXXI. VALERIANACE^E. 



Herbs (rarely suffruticose) ; with opposite leaves, no stipules, hermaphrodite 

 or sometimes polygamo-dicecious flowers in cymose inflorescence, a 5-merous 

 somewhat irregular epigynous corolla, bearing fewer (1 to 3, rarely 4) stamens 

 on its tube, an ovary invested by the calyx-tube, and of one to three cells, but 

 only one ovuliferous, a solitary suspended seed with a straight embryo and no 

 albumen. Limb of calyx none, or of lobes or teeth, or evolved on the fruit into a 

 kind of pappus. Corolla either obscurely or manifestly irregular (bilabiately, f ) ; 

 lobes imbricated in the bud. Filaments and style filiform : stigma undivided and 

 truncate, or minutely 3-cleft. Ovule anatropous. Fruit dry and indehiscent, a 

 kind of akene. 



1. VALERIANA. Calyx-limb of 5 to 15 setiform lobes, which are inrolled and inconspicu- 

 ous until fruiting, when they are evolute and form a kind of plumose pappus. Corolla from 

 campanulate-funuelfurm to salverform, the tube or body often gibbous or slightly saccate 

 anteriorly. Stamens 3. Ovary 1 -celled, and with mere vestiges of two lateral cells, ripen- 

 ing into a flattened akelie, which is mostly 1 -nerved on one face, 3-nerved on the other, 

 and with a more or less evident nerve at each margin, which marks the position of a sup- 

 pressed empty cell. Perennials (with hardly an exception), the roots with a peculiar scent. 



2. VALERIANELLA. Calyx-limb not pappose, in all ours more or less obsolete. Corolla 

 from short-fuunelform to salverform, with or without gibbosity, or sometimes a sac or spur 

 at base; limb 5-parted, from nearly regular to obscurely or plainly bilabiate, or 4-parted with 

 the posterior lobe notched or 2-cleft. Stamens 3, very rarely 2. Fruit various, the two 

 abortive cells sometimes obsolete and uerviform at the lateral angles, commonly enlarged, 

 sometimes converted into wings. Annuals, with entire or sparingly dentate or incised leaves ; 

 cauline sessile.

ORDER LXXII. DIPSACACE.E. 



Herbs (all of the Old World) ; with opposite or verticillate leaves, no stipules, 

 capitate and involucrate inflorescence ; the flowers subtended by bracts, and ra.-li 

 with a more or less obvious involucel, hermaphrodite ; calyx-tube adnate to the 

 one-celled simple ovary ; corolla epigynous ; stamens inserted on its tub.- alter- 

 nate with its lobes, of equal number or fewer, wholly unconnected; style fili- 

 form and stigma simple; ovule solitary and suspended, anatropous ; seed \\ith 

 a straight embryo in fleshy albumen. Corolla invgulur or nearly regular; llu- 

 lobes imbricated in the bud. Fruit an akene, more or less adnatc to the involucel 



which embraces it. 



SCABIOSA ATROPTTRFUREA, L, SWEET SCABIOUS of the gardens, is familiar : and one 

 or two of the following genus have become spontaneous. 



1. DfPSACUS, Tourn. TEASEL. (Greek and Latin name of Ten-el. 

 to come from S/r<fe, thirsty.) Flowers in a terminal head or short spike, in u hid., 




48 DIPSACACE^E. Dipsacus. 



however, the anthesis is not simply centripetal ; the subtending bracts and those 

 of the conspicuous polyphyllous and unequal involucre spiuescent. Involucel 

 calyx-like, prismatic, truncate and crenulate at the border, enclosing the whole 

 ovary and fruit, at length adnate to its thin walls. Calyx-limb cup-like, 4-toothed 

 or lolied. Corolla tubular-funnelform, 4-lobed, nearly regular. Stamens 4. 

 Stigma lateral. Coarse and rough or prickly biennials, with cauline leaves 

 mostly connate and cup-like at base. 



D. SYLVESTRIS, MILL. Prickly, 3 to 5 feet high : leaves lanceolate-oblong : involucre longer 

 thau-the head : flowers flesh-colored : bracts of the receptacle tipped with a long and straight 

 flexilile awn. Roadsides of the Eastern States: fl. summer. (Nat. from Eu.) 



D. FULLONUM, L. (FULLER'S TEASEL.) Probably an ancient derivative of the preceding: 

 involucre usually shorter than the cylindraceous head, at length reflexed : bracts of the re- 

 ceptacle rigid-spipescent, the tips recurved or hooked ; whence useful for raising a nap on 

 woollen cloth. Escaped from cult, in some places, apparently established in S. California. 

 (Nat. from Eu.) 



ORDER LXXIII. COMPOSITE. 



Flowers in an involucrate head on a simple receptacle, o-merous or sometimes 

 4-merous ; with lobes of the epigynous corolla valvate in the bud ; stamens as 

 many as corolla-lobes and alternate with them, inserted on the tube ; anthers con- 

 nate into a tube (syngenesious) ; style in all fertile flowers 2-cleft or lobed at sum- 

 mit and bearing introrse-marginal stigmas ; ovary one-celled, a single anatropous 

 ovule erect from the base, becoming an exalbuminous seed with a .straight embryo, 

 the inferior radicle shorter and narrower than the cotyledons ; the fruit an akene. 

 Tube of calyx wholly adnate to the ovary ; its limb none, or obsolete, or devel- 

 oped into a cup or teeth, scales, awns, or capillary bristles. Corolla with nerves 

 running to the sinuses, then forking and bordering the lobes, raivly as many 

 intermediate nerves. Anthers commonly with sterile tip or appendage ; the cells 

 introrse, discharging the pollen within the tube ; this forced out by the lengthen- 

 ing of the style, which in hermaphrodite and male flowers is commonly hairy- 

 tipped or appendaged. Pollen-grains globose, echinulate, sometimes smooth, in 

 Oichoriacece 12-sided. Leaves various: no trite stipules. Development of the 

 flowers in the head centripetal ; of the heads, when clustered or associated, more 

 or less centrifugal, i. e. heads disposed to be cymose. Juice watery, in some 

 resinous, in the last tribe milky. 



Heads homoyamous when all its "lowers are alike in sex ; hetcrogamous when 

 unlike (generally marginal flowers female or neutral, and central hermaphrodite 

 or by abortion male) ; androgynous when of male and female flowers ; monoecious 

 or dioecious when the flowers of separate sexes are in different heads either on 

 same or different plants ; radiate when there are enlarged ligulate flowers in the 

 margin ; wholly ligulate when all the flowers have ligulate corollas ; discoid 

 when there are no enlarged marginal corollas. When these exist they are some- 

 times collectively called the ray : the other flowers collectively occupy the disk. 

 The head (compound flower of the early botanists), in Latin capitulum, is also 

 named anthodium. Its involucre (periclinium of authors) is formed of separate 

 or sometimes connate reduced leaves, i. e. bracts (squamce or scales of De Can- 

 dolle, &c.) : the innermost of these bracts subtend the outermost or lowest flowers. 

 The axis within or above these is the receptacle (clinanthium of some), which

varies from plane to conical, or oblong, or even cylindrical or subulate. When the 

 receptacle bears flowers only, it is naked, although the surface may IK, alveolate 

 foveolate, or merely areolate, according as the insertion of the ovaries or akcnes 

 is surrounded or circumscribed by honeycomb-like or lesser elevations; or, when 

 these project into bristles, slender teeth, or shreds, it isjimbrillaf,-: it is paleaceous 

 when the disk-flowers are subtended by bracts; these usually cbaft-lik, . liim-fore 

 called palea, chaff, or simply bracts of the receptacle. In place of calyx-limb 

 there is more commonly a circle of epigyuous bristles, hairs, or uwns, the ^ >pu s, 

 a name extended to the calyx-limb of whatever form or texture : its parts are 

 bristles, awns, paleaj, teeth, &c., according to shape and texture. Corollas either 

 all tubular (usually enlarging above the insertion of the stamens into the tluwt, 

 and 4-5-lobed at summit, mostly regular) ; or the marginal ones strap-shaped, 

 i. e. lignJah\ the elongated limb (ligule) being explanate, and 3-fj-toothrd at the 

 apex. Such are always female or neutral, or, when all the flowers of the head 

 have ligulate corollas, then hermaphrodite. Anthers with basal auricles either 

 rounded or acute, or sometimes produced into tails (caudate}. Branches of the 

 style in female flowers and in some hermaphrodite ones margined with stigma, 

 i. e. stigmatic lines, quite to the tip ; in most hermaphrodite flowers these lines 

 shorter, occupying the lower portion, or ending at the appendage or hairy tip. 

 An immense order, comprising a tenth part of known phamogamous plants, an 

 eighth of those of North America.

 G. squurrosa and G. subdecurrens, with lunate-gibbous 10-ribbed akenes. It may reach the U. S. 

 borders. 



* Stem or branches (at least above) and sometimes the leaves pubescent: rays very numerous: 

 awns of the pappus 2 or 3, sometimes solitary: plants a foot to a yard high. 



-f- Atlantic and Mexican species: root in U. S. annual or biennial, perhaps more enduring in 

 Mexico: akenes with no terminal border or teeth. 



G. inuloides, WILLD. 1. c. Pubescence minute or short : leaves from oblong to lanceolate 

 or almost ovate, serrate down to the partly clasping or broad base with close-set and often 

 gland-tipped salient teeth : involucre glabrous (half-inch or more in diameter), at length 

 squarrose: akeues short and turgid (the length barely double the breadth), with rounded- 

 truncate summit and small areola, smooth or becoming corky-rugose transversely. Dunal,

-i -i Pacific species: root perennial but sometimes flowering the first year: akenes truncate and 

 with a prominulous irregularly undulate or obscurely 3-5-toothed border around the terminal 

 areola: pappus-awns stouter and more corneous, flattish: involucre in the same species either 

 naked or surrounded by spreading foliaceous bracts passing into leaves. 



G. hirsutula, HOOK. & ARX. A foot or two high, simple or sparingly branched, villous- 

 hirsute, or glabrate, sometimes even tomentose when young : leaves rather rigid and com- 

 monly serrate with rigid salient teeth, in the typical plant oblong, or lower ones spatulate 

 and obtuse (cauline inch or two long and about half-inch wide), upper with partly clasping 

 but not widened base, varying however to lanceolate and acute : heads solitary or few : in-

 canesceut pubescence. Westward, extending to the southern part of California, it usually 

 becomes more canescent and villous as well as hirsute and hispid ; the size and fulness 

 of the heads greatly varying. The more marked but quite unlimited forms are the fol-

 some European form of S. Virgaurea, although later plants cultivated under this name may be 

 derivatives of S. latifolia, L.

S. LITIIOSPERMIFOLIA, Willd. Euum. 891, referred to under S. sempervirens, L., was prob- 

 ably derived from that, under cultivation becoming pubescent and duller green. But without 

 the transitions as seen in S. inteyrifolia, Desf ., this would seem improbable.

 name for these and similar radiate-flowered and Daisy-like plants.) Herbs, 

 mainly of the northern hemisphere, and especially of North America, the larger 

 part perennial : fl. late summer and autumn. The yellow disk-flowers in several

The line between Aster and Erigeron is arbitrary. Aster is far the most difficult of our 

 genera, both for the settlement of the names of the species and for their limitation, in respect 

 to which little satisfaction has been attained as the result of prolonged and repeated studies. 

 For full reasons why the following Liuuajau species subside, see Proc. Am. Acad. xvii. supra cit. 



A. DiVARicArus, L. Founded, as to the specimen in the herbarium, upon the upper part 

 of a plant of A. cori/inln>.iii>s, Ait., wanting the cordate serrate leaves; as to the plants of Pluke- 

 net and Gronovius, upon A. hifirnms, Michx. 



A. lUGinrs, L. Founded wholly upon Clayton's plant as described in Fl. Virg. ; is a mere 

 synonym of A. linariifolius, L. 



A. LiNir6Lius, L., and A. HTSSOPIFOLITS, L. Mant., belong to Galatella, and are not Amer- 

 ican. The plant of Gronov. Fl. Virg., referred to, is A. tenuifolius, L. 



A. ANNUUS, L., is well known as Erigeron ami nits. 



A. VERNUS, L., is Erigeron nuflicatilis, Michx. 



A. MTJTABILIS, L. Not to be found in the Linna?an herbarium. In the first ed. of the Spec. 

 PI. was compared with an "A. serotimis,'' which was neither published nor preserved in the her- 

 barium, has as a synonym a plant figured by Plukenet which is not preserved in his herbarium : 

 finally, in ed. 2, the character was reconstructed in a manner incompatible with the original 

 one, and before the Pluke'netian synonym " Herm. Hort. Lugd. t. 67 " was introduced, which, 

 on the authority of the herbaria of Royen and of Sherard, is A. Icevis, L., and the comparison 

 was changed to one with A. Tradescanti, L. A. mutabilis of later authors belongs to older- 

 named species. 



A. MISER, L. Founded wholly upon a much exaggerated figure in Dilleuius, with fictitious 

 character, drawn from the plate. See A. n'minfHs, var. foliolosus. 



A. ciLiAxrs, Walt. Car. 209, is not at all identified.

A. diffusus, AIT. Either pubescent or almost glabrous, a foot to 4 or 5 feet high; the 

 larger plants widely and divergently branched : leaves thinnish, mostly broad! v lanceolate 

 or wider, with much narrowed base, acute or acuminate ; lower cauline generallv 3 to 5 

 inches long, sparingly and acutely serrate ; those of the flowering branches becoming small 

 and entire, some of them surpassing the crowded or sometimes more scattered heads, which 

 are usually disposed along the length of the flowering branches, either singly or in clusters ; 

 radical leaves ovate and slender-petioled : involucre campnnulate ; its bracts linear, obtuse or 

 sometimes acutish, and with a definite short green tip: rays small, white, or sometimes 

 tinged with purplish or violet. Ait. Kew. iii 205; Nees, Ast. 1. c., &c. A. divertjens, Ait.

 Dry or barely moist ground, Canada to Texas and west to Missouri. A. dijfusus is, on the 

 whole, the best of three names of same date. 



Var. horizontalis. A robust, very bushy-branched and exceedingly floriferous 

 cultivated form ; the leaves thickish, those of the widely spreading flowering branches small 

 and short, entire : white rays more conspicuous. A. horizontalis, Desf. Cat. ed. 3, 402. A. 

 recurvatus, Willd. Spec. iii. 2047. A plant of the gardens, not exactly matched by indige- 

 nous specimens, but evidently of this species. 



Var. thyrsoideus. From slightly to distinctly cinereous-pubescent: leaves from 

 ovate-oblong to lanceolate : flowering branches ascending, rather rigid, either short or some- 

 what elongated: heads thyrsoid-pauiculate or spicate-glomerate, less secund. Part of A. 

 miser, var. glomerellus, Torr. & Gray, 1. c. New York to Illinois and Upper Canada. West-

Var. hirsuticaulis (*-l. Itirxiifirmi/is, Lindl. in DC. Prodr. v. 242, and A. miser, var. 

 hirsuticaulis, Torr. & Gray, Fl. 1. c.), founded only on specimens from Albany, N. Y., Beck, 

 in herb. Torr. & Lindl., is a singular form, probably growing in much shade, with long and 

 narrow leaves, as of A. rimim </.s, the midrib of these beneath and the stem very hirsute. 

 Other forms in Torr. & Gray, FL, are ambiguous between this and A. ri/nineus. 



Var. bifrons. A luxuriant form, growing in shady and moist grounds, with large 

 and thin elongated-lanceolate leaves, and spreading branches with loosely disposed and mostly 

 larger heads: a transition to the following section and to A. pnnii-ulutiix, Lam. A. bifrons, 

 Lindl. in DC. Prodr. v. 243. Shady banks of Kentucky Eiver (Short) to Illinois. 



+ -j -f H 1 Involucre various, in some imbricated and with short close tips, as in the last 



preceding section, in others more loose and herbaceous : heads when numerous either thyrsoid- 

 or open-paniculate on erect or ascending branches. Vulyares. 



H- Cauline leaves sessile, but neither with cordate or aimculate base (except in forms of A. Novi- 

 Belijii and A. foliaceus), nor with abrupt winged-petiole-like lower portion. 



= Atlantic United States species, with branching stems or several or mnny heads when well de- 

 veloped, none alpine or subalpine: herbage disposed to be glabrous, but branches often pubes- 

 cent in lines. 



a. Involucre of the small or middle-sized heads close and erect ; its bracts narrow, imbricated in 

 successive lengths, the small green tips not dilated nor spreading. Species seemingly confluent 

 in a series. 



A. Tradescanti, L., partly. Stem slender, 2 to 4 feet high, with numerous erect or ascend- 

 ing branches and branchlets : leaves lanceolate or linear, slightly serrate or entire, tliinuish : 

 small heads numerous, corymbosely or somewhat racemosely paniculate, only two or three 

 lines high : bracts of the involucre linear, acutish, partly green at tip and down the back : 

 rays white, or sometimes tinged with lilac, only about 2 lines long. Spec. ii. .876 (as to

 Some forms, both cult, and wild, show affinity to A. diimosus, riminet/s, and dij/'iisns; others 

 differ from the next following species only in the smaller heads and flowers. 



A. paniculatus, LAM. Stem 2 to 8 feet high, freely and paniculately branched : leaves 

 from elongated oblong to narrowly lanceolate, mostly attenuate-acuminate, sharply serrate 

 or denticulate, or upper entire, thin : heads about a third of an inch high, in loose and open 

 mostly leafy panicles : bracts of the involucre narrowly linear, with tapering acute or acumi- 

 nate green tips (or outermost wholly green on back) : rays 3 or 4 lines long, white varying 

 to purplish or pale violet (in drying often turning blue). Lam. Diet. i. 306 (1783, the char,

 bly indigenous. A. lams, Willd. Euum. 886, seems to be a similar form. Low or moist 

 ground, New Brunswick to Saskatchewan, E. Montana, and Louisiana, abundant in the 

 Northern States, an-l polymorphous. A small and slender form, in Northern sphaguous 

 bogs, with linear leaves, resembles A. lonyifolius in habit and foliage. 



A. Salicifolius, (LAM.?) AIT. Resembles the preceding, equally branching: leaves com-

 fine reticulation of the veinlets manifest : involucre more imbricated ; its bracts firmer, 

 linear, with shorter and more definite green tips, these acute or obtusish : heads (as large as

 barium, is of flowering branches only, with small leaves. 



Var. Siobasper. A rigid and commonly scabrous form, with thyrsoid-eontracted and 

 foliose inflorescence : broad heads commonly foliose-bracteate : bracts of involucre broader

A. junceus, AIT. Slender, a foot to a yard high, the smaller plants simple-stemmed and 

 with few beads, smooth and nearly glabrous: leaves linear or nearly so (3 to 5 inches long, 

 2 to 4 lines wide), entire, or lower with rare deriticulations : involucre 3 lines high ; its bracts

Var. villicaulis. A small and low form, with simple stem (a foot or less high) and 

 midrib of narrow leaves beneath densely white-villous : heads few or solitary : rays deep

 paratively late-flowering. 



A. Novi-Belgii, L. Rather low, rarely tall, glabrous and smooth, or pubescent in lines on 

 the branches : leaves from oblong to linear-lanceolate, entire or sparsely or obscurely ser- 

 rate; upper with sessile base partly clasping and not rarely somewhat auriculate : heads 

 mostly 4 or 5 lines high and bright blue-violet rays of equal length. The commonest later- 

 flowered blue Aster of the Atlantic border, in low or wet grounds, truly polymorphous, both

 and linear iuvolucral bracts with narrow and acute spreading or recurving upper portion. 

 Common in wet grounds, New Brunswick and Canada to Georgia, chiefly eastward, but ex- 

 tending to Ohio and Illinois. A. eminens, var. virgineus, Lindl. Bot. Reg. t. 1656, appears to 

 be a nearly white-rayed form. A. laxus, Torr. & Gray, Fl. ii. 134, a very narrow-leaved

Var. laevigatus. Smooth and glabrous throughout or nearly so : leaves mostly ob- 

 long-lanceolate, little if at all thickened ; upper cauliue disposed to be half-clasping by an 

 abrupt or obscurely auriculate base : involucral bracts in few ranks, rather short, all not far 

 from same length, loosely erect, and with comparatively short acutish herbaceous tips ; thus 

 resembling A. versf color except that the involucral bracts are much less imbricated and little

the wild ; and a dwarf form, very floriferous, with small leaves and small heads, is A. c(rsj'- 

 tosus of the gardens (as cited by Liudley under A. culn/ti riniia), probably the parent also of 

 A. Novi-Beftjii, var. minimus, of the gardens, with rose-purple rays. Saline marshes and 

 shores, Canada and Xew England to Georgia : evidently passes into the thinner-leaved form 

 taken as the tvpe, wherever it recedes from the influence of brackish water. The old culti- 

 vated forms evidently much altered in the European gardens. 



Var. el6d.es. Slender, a foot or two high and simple, sometimes taller and with 

 simpler panicle : leaves thickish, long and narrowly linear (2 to 5 inches long, 2 or 3 lines 

 wide), entire; those of flowering branches or open panicle small and bract-like : involucre of 

 rather well-imbricated narrow bracts, with short and mostly spreading acutisli tips. A.

 ticulate leaves of thinner texture; and the broad-leaved var. of Torr. & Gray, 1. c., into the 

 preceding variety. 



Var. thyrsiflorus. Very leafy, smooth : cauline leaves narrowly lanceolate or 

 nearly linear (2 to 4 inches long, 2 to 4 lines wide below the middle), attenuate-acuminate, 

 commonly serrulate, of rather firm texture: heads numerous in a narrow thyrsoid panicle, 

 or somewhat racemosely paniculate on elongated branches, rather large : involucre of the 

 narrow bracts with attenuate and spreading or squarrose-recnrving tips, as in the typical form.

 ample : involucre mostly with conspicuous loose foliaceous lanceolate or broadly linear outer 

 bracts, which equal the inner, or sometimes more imbricated and squarrose : rays violet or 

 purple, in the larger heads nearly half-inch long. DC. Prodr. v. 228. Here made to in- 

 clude very various forms. The originals, from Uualaska and Sitka, are rather low, simple, or 

 simple-stemmed with short monocephalous branches, leafy about the heads : farther south it 

 becomes more branching, 2 or 3 feet high ; generally differing from the preceding species 

 in the ampler and broader as well as entire leaves, disposed to be half-clasping at base, and 

 the leafy-bracted or much greener involucre. A. Douylasii, Eaton, Bot. King Exp. 141, &

 upper often with clasping base : heads solitary or few, naked-pedunculate, broad : involucral 

 bracts linear-lanceolate, loose and not imbricated, all equalling the disk, occasionally the 

 outermost broader and leaf-like. A. adscendcns, var. Purr/ji, Eaton, Bot. King Exp. 139.

Var. Parryi. Includes some ambiguous forms, seemingly between the preceding 

 variety and A. Fremonti, with stems a span to a foot high, with smooth and thickish rather 

 large leaves, mostly naked heads; the involucre sometimes foliaceous-bracteate in the man- 

 ner of the present species, sometimes wholly of the narrow and closer bracts of A. 

 Fremonti. With that species this has been referred to A. adsccndens. Rocky Mountains of 

 Colorado, subalpine, Parry (417), Hall & Harbour (253), Vasey (251), &c., and S. Wyoming, 

 H. Engelmann. 



Var. Burkei. A foot or two high, rather stout, simple or branched above, leafy to 

 the top : leaves thickish, very smooth, ample ; upper cauline mostly oblong, and with 

 broadly half-clasping usually auriculate insertion : heads solitary or several, very broad : in- 

 volucre of oblong or spatulate and obtuse loosely imbricated bracts, the outer commonly 

 shorter, or outermost sometimes more foliaceous and equalling the disk. Km-ky Mountains, 

 Burke in herb. Hook. Siincoe Hills, Washington Terr., Howell. Wahsatch Mountains at 

 Alta, Utah, M. K. Jnnrs. Mogollon Mountains, New Mexico, and Arizona, Rnsby. 



Var. Canbyi. Like the preceding form in foliage, apparently tall and stout (base of 

 stem and lower leaves wanting), leafy throughout the thyrsoid panicle of numerous sub- 

 sessile heads: these comparatively small: upper leaves (only ones seen) rather broadly 

 oblong and with broad half-clasping base obscurely auriculate : bracts of the involucre im- 

 bricated, with small and erect lanceolate green tips, only in some heads a few of the outer- 

 most loose and foliaceous, but seldom equalling the disk. On White River in Western 

 Colorado, Vasey, 1868, distributed under the name of A. Canbyi, Vasey; perhaps a distinct 



species.

The first of the following species may fairly retain the now established name, 

 rather than have a new one made ; but Conyza bifrons was founded by Linnanis 

 on European Inula:, viz. on Hermann's figure, which in ed. 2 he refers to that 

 genus, and on one of Plukenet's (mistaken for Canadian), which is certainly 

 /. bifrons, as his herbarium shows. Of the many names for our second species,

 may probably remain as a subgenus, Diomedia, Bertero and Colla, not Cuss. -

 of source, which Besser made a var. Americana of A. rariabills, Tenore, is without much doubt 

 European. The plant of Eugelmann, referred to by Besser in Liunrea, xv. Ill, is an imperfect 

 specimen, probably of A. Canadensis.

 fewer and sometimes irregularly concreted at base in pairs or phalanges. The 

 species are polymorphous and not readily limited. 



L. ramulosa, GRAY, p. 162. Tack-shaped glands abound on the margins of the leaves 

 whenever these .are rigid : pappus-bristles inclined to unite at base into five phalanges. 



Var. adenophora. Tack-shaped glands conspicuous, even on involncral bracts: 

 heads only about 8-flowered : pappus of few bristles in 5 paleaceous-aristiform phalanges, or

 subradical heads, some elevated 3-4-cephalous shoots have developed. 



48. ASTER. P. 172, &c. The following omitted names to be added in 

 their places, chiefly as synonyms. 



A. INTYBACEUS, Kuntli & Bouche, Adn. Ind. Sem. Hort. Berol. 1845, & Ann. Sci. Nat. 

 ser. 3, v. 358, according to an original specimen, is A. Tartaricus, L. f., wrongly taken for 

 North American. 



A. SALSUGINOSUS, Less, in Linn. vi. 124 (not Richards.), is A. Sitriricus, L., fide Herder. 



A. GRAVEOIJSNS, Nutt. Trans. Am. Phil. Soc. ser. 2, vii. 294, is a syn. of A. obiongffolius, 

 Nutt., on p. 178. 



A. PUBESCENS, Nees, Syn. Ast. 16 (A. heterophyl/us, var. Nees, Ast. 55), is a form of A. sagitti- 

 folius, Willd., p. 182. 



A. PINIFOLIUS, Nees, Syn. Ast. 29 (referred to A. Tradcscanti in Nees, Ast. 103), seems to 

 be A. i>o!>//>Iiij//nx, Willd , p. 184. 



A. AUGUSTUS, Nees, Syu. Ast. 26 (referred, along with A. rigidulus, Syn. Ast. 29, to A. belli- 

 dijlorus in Nees, Ast. 97, seems to be a cultivated form of A. paniculatus, Lam., p. 187. 



A. EMINENS, Nees, Ast. 87, is a mixture. The leading form is either A. junceus, Ait. (cited 

 by Nees as a synonym), or A. paniculatus, to which some of the varieties seem to belong; the 

 var. /.cevigatus is our A. Novi-Bt/yii, var. kecigatus (to which his synonym points) ; other forms 

 are more obscure. 



A. LUXURIANS (Spreng. Syst. iii. 538), Nees, Ast. 538, is a broad-leaved form of A. Novi- 

 Bd/jii. 



A. UMBELI/ATUS, Mill., should have the svn. supplied : Dcellingeria umbel/ata, Nees, Ast. 178, 

 a broad-leaved form. 



A. VIRGATUS, Nees, Syn. Ast. 27 (not Ell.), is a form of A. Novi-Bel/jii, L., p. 189. 



The above determinations from Nees were derived from a set of cultivated Asters supplied 

 by Nees to Hohenacker (either directly or indirectly), thence to Dr. Klatt, who obligingly gave 

 them to the author. 



A. HAYDENI, Porter in Hayden, Geol. Rep. 1871 (published 1872), 485, is a syu. of A. pul- 

 cheilus, Eaton, p. 201.

 tomeutnm. From the habitat, the Encelia-like aspect, and the whole description, this is evi- 

 dently Encella nicea, Beuth. Bot. Sulph. 27, the new specimens with peduncles even longer than 

 described, and the bracts of the involucre come near to ovate-lanceolate. The small and narrow 

 paleaa of the pappus are so very caducous from the ovary that Beutham overlooked them.

L. heterotridia, HOOK. & ARN., p. 315. Pubescence all short and fine; hispid or hirsute 

 hairs none or few in the original specimens, but moderately developed in a form which is

 pointless divisions : heads sessile and clustered at summit of the short leafy branchlets : in- 

 volucre 12-14-toothed,. nearly naked at base : rays 10 or 12, the showy oblong ligules (2 lines 

 long) bright white ; the disk-flowers yellow. Arizona, on the mesas near Tucson, 1884, 

 Princjle. A handsome species, anomalous for its heterochromous flowers ; and hi other re- 

 spects serving to connect the first two sections with true Hymenatherum. 



178. ARTEMISIA, Tourn. 



A. SCOpulorum, GRAY, p. 369. Strike out var. monocephala, and add : 



A. Patterson!. More dwarf and white-tomento'se, but sometimes glabrate in age : leaves 

 3-5-parted or cleft, or uppermost entire : heads much larger and broader, solitary or 2 to 5, 

 40-50-flowered : corollas glabrous : receptacle extremely long-woolly. A. scopulorum, var. 

 monoce/ihala, Gray. Lower alpine region of the Kocky Mountains in Colorado, first coll. by 

 Parry in 18G2, and noted as distinct, and now well distinguished by Patterson. 



189. TETRAD YMI A, DC. EUTETRADTMIA, p. 379, add : - 



T. stenolepis, GREENE. Very white-tomentose with appressed wool, armed with long and 

 slender leaf-spines ; also bearing from narrowly spatulate to linear-subulate primary leaves : 

 heads full)- half-inch long, 5-flowered, bracteate with one or two small narrow leaves : bracts 

 of the involucre linear or broader, rigid and thick : akenes pubescent when young ; pappus 

 copious, rather rigid. Bull. Calif. Acad. i. 92. S. E. California, at Tehachapi Pass and 

 Antelope Valley, Mrs. Layne-Curran, J. C. Oliver. Habit of the second, but characters of 

 the first section of the genus. 



190 1 . BEBBIA, Greene. (Michael S. Bebb, of Illinois, specially notable for 

 his knowledge of Willows.) Heads homogamous, 20-30-flowered ; flowers all her- 

 maphrodite and fertile. Involucre campannlate, shorter than the disk ; its bracts 

 imbricated in two or three series, oblong or ovate, appressed ; outermost short 

 ones nearly herbaceous ; inner partly or wholly scarious and obscurely nervose 

 when dry, a few of the innermost among the outer flowers. Receptacle other- 

 wise naked, flat. Corolla with short proper tube and elongated upwardly enlar- 

 ging throat, 5-toothed ; the teeth ovate, spreading, hispidulous outside. Style- 

 branches slender and produced into indistinct subulate hispidulous appendages. 

 Akenes somewhat turbinate, hirsute, obsoletely 5-nerved and many striate. Pap- 

 pus of 15 to 20 rigid short-plumose bristles in a single series. Greene in Bull. 

 Calif. Acad. i. 179. Carphephorus, Kuknioides, Gray, p. 113. 



B. juncea, GREENE, 1. c. Shrubby at base, fastigiately much branched, a yard or less high ; 

 flowering branches rush-like, herbaceous or mainly so, mostly leafless and alternate, bearing 

 solitary or scattered heads : leaves few or sparse ; lower opposite, oblong to linear, the lar-

ger often laciniate and petioled ; upper small and linear, or reduced to subulate minute 

 scales: flowers golden yellow, sweet-scented (somewhat as in those of Acacia Farnesiana). 

 Carphephores junceus, Beuth. & p. 113. B. utriplicifolia (Carphephorus atriplicifolius, Gray, 

 1. c.) of Lower California is probably the same, and var. aspera, Greene, 1. c., is a commo'n 

 hispidulous state. Rocky places, in canons, &c. in the arid regions of Arizona and S. E. 

 California (Lower Calif., first coll. by Hinds). Evidently an outlying representative of the 

 subtribe Liabece. 



192. SENECIO, Tourn. 



S. aureus, Var. Balsamitae, p. 391. Add syn. : S. ceratopkyllus, Nees, PI. Neuwied 

 Trav. 12. 



S. Neo-Mexicanus, GRAY, p. 392. S. Austins, Greene, Bull. Calif. Acad. i. 93, is 

 probably a form of this, from the northeastern borders of California, in Modoc Co., J)/?-s. 

 Austin. 



S. Lyoni. (Next after 5. eremopliilus, p. 393.) Obscurely stiff rutescent, and somewhat 

 succulent, early glabrate except the persistent dense tufts of wool in the axils : leaves once 

 or twice prinnately parted into linear obtuse segments and lobes, glabrous above, minutely 

 woolly-pubescent beneath : peduncle bearing a few pedicellate heads (these 4 to 6 lines 

 high and radiate): pedicels and involucre sparingly subulate-bracteolate. Island of San 

 Clemeute, off S. California, on cliffs by the sea, Nevin & Lyon, April, 1885. 



S. Calif ornicus, DC. Growing in sand along the sea-shore (San Diego and southward) it 

 becomes succulent and dwarf, when it is S. amnmpltilus, Greene, Bull. Calif. Acad. i. 193. 



At the end of the genus, p. 394, add : 

 * * * * Indigenous winter-annual : heads with few and minute ray-flowers, or none. 



S. Mohavensis. Glabrous, branching from the base, leafy up to the loose corymbiform 

 panicle: leaves soft and thickish, ovate or oblong, sinuate-dentate or sparingly incised, cau- 

 linewith auriculate or cordate-clasping base: heads slender-pednncled, 4 lines high: involucre 

 narrow-campanulate, 18-20-flowered; calyculate bracts few and inconspicuous: ray-flowers 

 when present mostly difformed and biligulate, not surpassing the disk: akeues canesceut. 

 S. E. California in the Mohave region, near the Colorado, Lemmon. (Also within the bor- 

 ders of Sonora, Mex., Pr ingle.) 



213. STEPHANOMERIA, Nutt. 



S- COronaria, Greene, Bull. Calif. Acad. i. 194, Santa Lucia Mountains, Brandegee, by the 

 character seems too like S. exirjua, Nutt , p. 414. 



219. MICR6SEBIS, SCORZONELLA. At end, p. 418, add: - 



M. Howellii, GRAY. A foot or more high from a fusiform root, slender, bearing solitary 

 or 2 or 3 heads: leaves (only 2 or 3 lines wide) elongated-linear and attenuate, some bearing 

 a few attenuate refracted lobes ; involucre half-inch high, narrow, 1 5-20-flowered ; its bracts 

 all acuminate ; inner oblong-lanceolate and all nearly equal; outer much shorter and mostly 

 ovate: akenes 3 lines long, narrower at base : pappus of 8 or 10 conspicuous and firm lance- 

 olate palese, which nearly equal the length of the akene and bear a denticulate-scabrous awn 

 of hardly greater length ! Proc. Am. Acad. xx. 300, where by some mistake the pappus 

 is quite wrongly described. Waldo, S. \V. Oregon, June, 1884, Ilowell. Ambiguous be- 

 tween the sections Scorzonella and Calais, with pappus-palere of the latter, except in number, 

 but perennial or biennial from a fusiform root, and the habit of a slender M. leptosepala. 



223. MALAC6THBIX, DC. 



M. Coiilteri, GRAY, p. 421. Anthesis vespertine or matutinal, the heads closed at 



midday. 

 M. insularis, GREENE. Intermediate between Mcdacolepis and Malacothrix subsection 



Malacomeris, annual, glabrous, a foot or two high : leaves oblong-lanceolate, laciniate-pinna- 




COMPOSITE. 455 



tifid, the lobes almost linear : involucre well imbricated, less than half-inch high ; outermost 

 bracts ovate, innermost linear, all scarious with green or purplish tip and centre : corolla 

 yellow : receptacle almost destitute of bristles : akeues 15-ribbed, five of the ribs angulate- 

 prominent : one or two stronger pappus-bristles persistent. Bull. Calif. Acad. i. 194. 

 S. California, on Coronados Islands, off San Diego, Greene. 



M. foliosa. Between J\f. obtusa and M. inainu, p. 423, with habit of M. saratilis, but an an- 

 nual, with much smaller heads of yellow flowers, glabrous : stem a foot or two high, erect, 

 much branched, very leafy even to the branchlets : leaves lanceolate, most of them laciniate- 

 pinnatifid, 2 to 4 inches long, uppermost linear-attenuate : heads short-pecluncled, 3 to 5 lines 

 high : bracts of the involnare lanceolate, rather obtuse : akeues somewhat equally 10-costate : 

 pappus wholly deciduous, leaving neither bristles nor crown. Island of San Clemente, off 

 Southern California, Nevin & Lijon, April, 1885. Connects the Leucoseris of Nuttall with 

 his Leptoseris. 



M. saxatilis, TORK. & GRAY, p. 423. Under this may be more than one species, not only 

 the M. tenuifotia, Torr. & Gray, but also a larger-flowered one, M. altixsima, Greene, Bull. 

 Calif. Acad. 1. c., of mountains of Kern Co., Mrs. Lai/ne-Curran, said to be annual (but not 

 seen here) : probably same from Ojai, Peckham. But the characters are not yet clear. 



226. HIEBACIUM, Tourn. 



H. longipilum., TORR., p. 426. Cancel the var. spathulatum, which should be trans- 

 ferred to 



H. Marianum, WILLD., var. spathulatum. A mountain form, with leaves all or 

 mainly radical and unusually barbate-hispid. Pilosella spathulata, Schultz Bip. in Flora, 

 1862. Tuscarora or Two-top Mountain, Perm., Porter and Trail!. Green. 



H. Brandegei, Greene, Bull. C'alif. Acad. i. 194. Santa Lucia Mountains, Brander/ee, fide

PREFACE. 



THIS volume commences where the Flora of North America by Torrey 

 and Gray stopped, thirty-five years ago, namely at the close of the great 

 order of Composite; and the present part comprises the remaining 

 Gamopetalse. It is intended to complete this Synoptical Flora in two 

 volumes, of about 1200 pages each ; the first to cover the ground which 

 was gone over in the work referred to (now wholly out of print as well 

 as antiquated), that is, to contain the orders from Ranunculaceee to Com- 

 positse, newly elaborated. The next ensuing part of the present volume 

 will be devoted to the Apetake and Gymnospermse, and the final portion 

 to the Monocotyledones and the Vascular Cryptogamia. 



Botanists will need no particular explanation of thj3 plan of this work. 

 Geographically it comprises the United States and all the North Amer- 

 ican continent and islands northward, Greenland excluded. The series 

 of Natural Orders adopted is that of Bentham and Hooker's Genera 

 Plantarum. The generic characters are given synoptically, but with 

 essential completeness, at the beginning of each order. The characters 

 of sections of genera, when of comparatively high rank, are designated by 

 the sectional mark () and printed in the larger type ; and those of 

 first importance, such as may be termed subgenera, are distinguished by 

 having a substantive name. Subsections, and also primary divisions 

 when of low rank, are in small type. Such subdivisions are very freely 

 made, for convenience of analysis and to save repetition of identical 

 phrases under the included species ; and they are preferred to artificial 

 keys to the species, because enabling these to be grouped more naturally. 

 If somewhat less facile for rapid determination, they are more ex- 

 haustive and less liable to mislead ; and they permit the ultimate specific 




v i PREFACE. 



characters to be more simply diagnostic. In monotypic genera, it has 

 been found more convenient to give the details under the species, in 

 the form of a specific character. Throughout the work, from the order 

 down to the species or variety, the endeavor is to avoid repetition of 

 statement. 



The names of introduced species, sufficiently established to claim a 

 place in our flora, are printed in small capitals, as are such adventitious 

 or extraneous species as require mention. 



In the accentuation of generic, sectional, and specific names, no 

 attempt is made (as in the Manual of Botany of the Northern United 

 States and other works) to mark the quality of the accented vowel, but 

 only to designate the syllable upon which the principal accent falls. 



Compactness being essential, only the leading synonymy and most 

 important references are given, and these briefly. All deficiency in this 

 respect will be amply supplied by the Bibliographical Index to North 

 American Botany, prepared at the Harvard University Herbarium 

 by Sereno Watson, and now in course of publication by the Smith- 

 sonian Institution. The first part of this most important adjunct to the 

 present work, which is just issued, gives the full bibliography of the 

 Polypetalse (the subject of the first volume of Torrey and Gray's Flora 

 of North America, published in 1838 and 1840), with revision, critical 

 corrections, and additions np to the present time. Its continuation may 

 be expected to proceed pari passu with this Flora. 



HARVARD UNIVERSITY HERBARIUM, 



Cambridge, Massachusetts, April 10, 1878. 



IN this edition many corrections have been made upon the electro- 

 type plates ; but larger ones are given in the Supplement, along with 

 additions of new material and the re-elaboration of old. Page 68 and 

 pages 389-392 have been reconstructed, and a full Index is added.

DIVISION II. GAMOPETALOUS DICOTYLEDONOUS PLANTS 



CONTINUED AFTER COMPOSITE. 



ORDER LXXIV. GOODENIACE^E. 



SHRUBBY or herbaceous plants, chiefly with alternate leaves and no proper 

 stipules, most resembling Lobeliacece, especially in having the corolla cleft down 

 between two of the lobes more deeply than between the rest ; but without 

 milky juice, the anthers separate, and a cup-like indusium around and at first 

 enclosing the stigma. Mainly Australian and Oceanic, one or two species of 

 the following genus reaching or overpassing the northern tropic. 



1. SC-<?EVOLiA, L. (Diminutive of scava, a left-handed person; application 

 obscure.) Calyx adnate to the 2-celled ovary ; the limb 5-cleft or a mere border 

 around the base of the epigynous 5-lobed corolla, the tube of which is cleft down 

 one side to the base ; its lobes valvate-induplicate in the bud. Stamens 5, 

 epigynous, or lightly connected with the base of the corolla, alternate with its 

 lobes, distinct. Ovules solitary or a pair in each cell, erect. Fruit drupe-like, 

 or when dry nut-like. Flowers in axillary cymes, or sometimes solitary. 

 L. Mant. 145 ; Benth. & Hook. Gen. ii. 539. 



S. Plumieri, Vahl. Low and shrubby, with fleshy obovate entire leaves, woolly-bearded in 

 the axils, otherwise smooth : livnb of the calyx a truncate border : corolla white, an 

 inch long; the tube as long as the lobes, very woolly inside. Lobelia, Plum. Ic. t. 165; 

 Catesb. Car. i. t. 79. Seashore, S. Florida. (W. Ind., S. Afr., S. Asia.) 



ORDER LXXV. LOBELIACE^E. 



Herbs (out of the tropics), the juice usually milky and acrid, with alternate 

 simple leaves, no stipules, racemose inflorescence, and perfect 5-merous flowers ; 

 having the calyx-tube adnate to the ovary, epigynous irregular corolla and sta- 

 mens, the latter as many as the lobes of the corolla and alternate with them, and 




2 LOBELIACE^E. Nemacladus. 



usually both syugenesious and inonadelphous. Limb of the calyx divided down to 

 the ovary, which is wholly inferior or sometimes a large part free ; its lobes generally 

 persistent. Corolla (with the stamens) inserted just where the calyx becomes 

 free from the ovary, its lobes mostly valvate or induplicate in the bud, commonly 

 deeper cleft or completely split down between two of the lobes, the cleft mostly on 

 the upper side (next the axis of inflorescence) in the open blossom, but becoming 

 so by a twist ; in the early bud the cleft looks toward the bract. The 5 petals 

 occasionally disposed to separate from below upward, and the limb to be bilabiately 

 irregular. Filaments generally free from the corolla, sometimes more or less ad- 

 herent to its tube : anthers 2-celled, introrsely dehiscent, firmly united around the top 

 of the style into a ring or short tube (except in an anomalous tribe). Ovary 

 2-celled with placentae projecting from the axis, or sometimes 1-celled with 2 

 parietal placentas. Style entire : stigma commonly 2-lobed, girt with a rim of 

 hairs. Ovules and seeds mostly indefinitely numerous, small, anatropous. Embryo 

 small or narrow, straight, in the axis of fleshy albumen. (Too near the Cam- 

 panulacece, and nearly passing into them, therefore united by recent authors ; but 

 as there are two dozen genera, agreeing in the indefinite inflorescence, irregular 

 corolla, and mostly in the syngenesious anthers, it seems best to retain the order.) 

 TRIBE I. CYPHIE^E. Anthers entirely separate, merely surrounding- the stigma. 



1. NEMACLADUS. Calyx partly or wholly free. Corolla bilabiately irregular; lower 

 lip 3-, upper 2-lobed or parted. Filaments monadelphous above the middle: anthers oval, 

 glabrous. Style incurved at tip : stigma capitate, 2-lobcd, obsoletely annulate. Capsule 

 2-celled, 2-valved from top, 20-40-secded. 



TRIBE II. LOBELIE^E. Anthers syngenesious. CoixxLla truly gamopetalous, at least 

 above, in ours distinctly bilabiate, two lobes turned away from the other three. 

 * Corolla open down to the base on one (the apparently upper) side. 



2. LOBELIA. Calyx-tube short. Corolla with tube commonly straight; the lobe each 

 side of the cleft erect or turned backwards ; the three others larger and somewhat combined 

 to form the spreading or recurved (apparently) lower lip. Stamens free from the tube of the 

 corolla, monadelphous except near the base. Capsule thin-walled, 2-celled, many-seeded, 

 loculicidally 2-valved at the top or free upper part. 



* * Corolla with a closed tube : capsule wholly inferior. 



3. PALMERELLA. Calyx-tube turbinate ; the lobes slender. Corolla with an elongated 

 linear and straight tube, not at all dilated at the throat ; the short limb abruptly spreading; 

 two lobes small, spatulate-linear and recurving ; the three larger obovate or oblong and 

 slightly united at base. Filaments more or less adnate to the corolla up to near the throat, 

 then monadelphous and free, or farther adnate on one side only : anthers oblong; the three 

 larger naked; tl>e two shorter tipped with a tuft of very unequal stout bristles. Stigma, 

 ovary, and probably capsule as in Lobelia. 



4. LAURENTIA. Calyx-tube turbinate or oblong. Corolla with its tube as long as the 

 limb, which is like that of Lobelia. So are the stamens, pistil, &c. Capsule short, 

 2-valved at the summit. 



5. DOWNINGIA. Calyx-tube very long, stalk-like. Corolla with a very short tube, and an 

 ample bilabiate limb; lips spreading, the larger 3-lobed and broad; the two distinct divi- 

 sions of the smaller narrower. Anther-tube incurved: one or both of the shorter an- 

 thers tipped with a stout bristle-like point; the others naked. Ovary at first two-celled. 

 Capsule very long and linear, crowned with the foliaceous and linear calyx-lobes, terete 

 or 2-3-angled, early becoming 1-celled with 2 parietal and many-seeded filiform placenta, 

 remaining closed at the narrow apex, dehiscent longitudinally by from one to three long 

 fissures or valves. 



1. NEMACLADUS, Ivutt. (A r /;ju, a thread, and xP.<5o b -, branch, from the 

 very slender stem and branches.) -- Two small annuals a span high, at length 

 excessively branched and diffuse : leaves minute ; the radical obovate ; cauline 

 reduced to subulate bracts : pedicels capillary, racemose on zigzag branches : 

 corolla flesh-color. Gray in Jour. Linn. Soc. xiv. 28. 




Lobelia. LOBELTACE^E. 6 



N. ramosissitnus, Ntltt. Glabrous, except the minutely pubescent tuft of radical 

 leaves : calyx 5-clef t ; its tube turbinate, adnate to the lower third of the ovary and round- 

 ish capsule, which does not exceed the rather unequal lobes: corolla short (a line long), 

 soon separating into 3 or 5 parts or petals : filaments monadelphous above : seeds oblong- 

 oval. PI. Gamb. (Trans. Am. Phil. Soc. n. ser. viii.), 254 ; Torr. Mex. Bound. 108, t. 35. - 

 Gravelly or sandy soil, California to New Mexico. 



N. longiflorus, Gray. Radical leaves more canescent : calyx '5-partecl, free from and 

 much shorter than the narrow oblong capsule, its lobes equal : corolla narrower, firmly 

 gamopetalous, fully 3 lines long, 3 or 4 times longer than the calyx : filaments long-mona- 

 delphous : seeds short-oval. Proc. Am. Acad. xii. 60. S. California, Wallace, Lemmon. 



2. LOBELIA, L. (Commemorates Matthias de l'0bel, latinized Lobelius, an 

 early Flemish herbalist.) Ours herbs, flowering in summer, some of them showy ; 

 common in the Atlantic, almost absent from the Pacific United States. Tube 

 of the corolla more or less disposed to split up in age into three pieces or into 

 its five petals ; at least the two shorter anthers with a bearded tuft at tip. 



1. MOMOCHI'LUS, A. DC. Lips of the corolla somewhat equal; one of them 

 3-toothed, the other 2-parted : flowers long-peduncled from the axil of leaves 

 or large leafy bracts, in ours red and yellow : perennials. 



L. laxiflora, HBK., var. angustifolia. Tall and branching: leaves lanceolate or 

 even linear, 3 or 4 inches long, denticulate : peduncles 2 to 4 inches and corolla an inch 

 long: calyx-lobes hardly longer than the tube. L. persiciefolia, HBK., not Lam. L. 

 CavaniUesii,Marl.; Hook. Bot. Mag. t. 3000. Damp ground, just below' the Mexican 

 border of Arizona, north of Arispe, Thurber. (Mex.) A form intermediate in the breadth 

 of the leaves between the var. and the L. Cavanillesii, Cav. Ic. t. 518, or the plant culti- 

 vated as Siphocampylus bicolor. Anthers sometimes long-hirsute externally, sometimes 

 nearly naked. 



2. EULOBELIA. (Eiilobelia, Hemipoyon, & ffolopogon, Benth. & Hook.) 

 Larger lip of the corolla 3-parted or o-cleft and spreading or dependent ; tho 

 other two lobes either erect or turned backward: flowers racemose or spicatc. 



* Flowers bright red, large and showy, on erect or ascending pedicels in a virgate raceme : larger 

 anthers naked at tip: perennial from slender offshoots, the flowering plants dying throughout in 

 autumn. 



L. cardinalis, L. (CARDINAL-FLOWER.) Minutely pubescent or glabrous: stem 2 to 4 feet 

 high, commonly simple : leaves from oblong-ovate to oblong-lanceolate, tapering to both 

 ends, irregularly serrate or serrulate : lower bracts leafy : tube of calyx and capsule hemi- 

 spherical, much shorter than the subulate linear lobes : tube of the corolla about an inch 

 long: seeds oblong, rugose-tuberculate : the intense red of the corolla varying rarely to 

 rose-color or even white. Bot. Mag. t. 320; Bart. Med. Bot. t. 48. Wet ground, New 

 Brunswick to the Saskatchewan, Florida, and the borders of Texas. 



L. splendens, W^illd. More slender, glabrous or nearly so : leaves lanceolate or almost 

 linear, glandular-denticulate, all but the lower sessile : seeds less tuberculate : otherwise 

 very like the preceding. Hort. Berol. t! 86, the corolla-lobes larger and longer than in 

 wild specimens. L. Texensis, Raf. Ann. Nat. (1833) 20. Wet grounds, Texas and through 

 New Mexico and Arizona to southern borders of San Diego Co., California, Palmer.

ORDER LXXVI. CAMPANULACE.E. 



Herbs, with bland milky juice, alternate simple leaves, no stipules, and regular 

 5-merous flowers ; the tube of the calyx adnate to the 2-5-celled many-ovuled 

 ovary ; the corolla and 5 stamens (alternate with its lobes) inserted where the 

 calyx becomes free, or the latter adnate merely to the base of the corolla ; fruit a 

 many-seeded capsule, rarely baccate. Calyx persistent, usually divided down to 

 the ovary. Corolla valvate, induplicate, or rarely imbricate in the bud. Stamens 

 mostly distinct : anthers with 2 parallel cells, introrse. Style one, almost always 

 pubescent or puberulent for some distance below the 2 to 5 introrse stigmas. 

 Ovules anatropous, on placentre projecting from the axis. Seeds small, usually 

 smooth. Embryo straight in the axis of fleshy albumen. Flowers often showy ; 

 the corolla commonly blue or in the same species white, and withering rather than 

 deciduous. In fertilization proterandrous ; the anthers opening in the bud, dis- 

 charging their pollen upon the style, where it accumulates upon the collecting 

 hairs or pubescence ; the stigmas (then firmly conniving) maturing and diverging

upward, the salient keels running to the apex of the lobes and to the sinuses, the 

 limb imbricated in the bud. Anthers free and on erect filaments in the early 

 bud, in the full-grown bud received in the pouches of the corolla, and the fila- 

 ments bent over as the corolla enlarges, and still more when it expands, straight- 

 ening elastically and incurving when disengaged, thereby throwing out the pollen : 

 anther-cells opening by a large pore, sometimes extending into a chink. Stigma 

 depressed. Capsule globular, o-celled : placentas pendulous or porrect from the 

 upper part of a small columella. Seeds with a thin and mostly close coat.

ORDER LXXXII. MYRSINEACE^E. 



Shrubs or trees, with the floral characters of Primulacece, i. e. stamens of the 

 number of the petals or corolla-lobes and opposite them, undivided style and 

 stigma, and a one-celled ovary with a free central placenta, bearing few or 

 numerous peltate amphitropous ovules. These are generally immersed in the 

 placenta, and only one usually matures into a seed. This is globose, with a thin 




Ardisia. MYRSINEACE.E. 65 



coat, and a copious cartilaginous albumen. The fruit is pea-shaped, usually dry- 

 drupaceous, never capsular. Leaves simple, mostly alternate, without stipules, 

 commonly marked with some immersed dots or short lines, containing at first 

 pellucid but at length dark resinous matter ; these also appearing in the flower, 

 especially in the corolla. (There are similar dots or lines in Lysimachia, of the 

 preceding order.) No milky juice. Flowers small and the corolla short, rotate 

 or campanulate. A tropical order, sparingly reaching the southern borders of 

 the United States. 



TRIBE I. MYRSINEzE. Calyx perfectly free. No staminodia. Ovules usually im- 

 mersed in the fleshy placenta, only one maturing into a seed which fills the cavity 

 of the fruit.

 4-5-partcd, imbricated in the bud. Anthers short and usually blunt. 



2. ARDISIA. Flowers in panicles, either terminal or from the upper axils. Corolla rotate, 

 5- (rarely 4-6-) parted ; the lobes convolute in the bud, or sometimes one wholly exterior. 

 Anthers lanceolate-sagittate, pointed ; the cells dehiscent from the apex downward. 



TRIBE II. TIIEOPHRASTEzE. Calyx perfectly free. Staminodia or sterile sta- 

 mens in the throat at the sinuses of the corolla. Ovules numerous, not immersed 

 in the. placenta, maturing few or numsrous seeds. 



3. JACQUINIA. Calyx 5-cleft, with lobes rounded and much imbricated. Corolla short- 

 salverform or campanulate ; lobes rounded, imbricated in the bud : a rounded petaloid 

 appendage (representing a sterile stamen of the outer series) in each sinus. Stamens 5, 

 inserted low down on the tube of the corolla : filaments subulate : anthers oblong or 

 ovate, extrorsely dehiscent. Fruit ovoid or globose, leathery, pointed with the base of 

 the style. Seeds few, imbedded in the mucilage of the placenta. Embryo with ovate 

 cotyledons and slender radicle.

 pointed anthers, which are often connivent around the acute style, forming a 

 prominent cusp in the centre of the flower.) A large and wide-spread tropical 

 genus, with white or rose-colored corolla, and white, red, or blue berry-like fruits. 

 Our only species differs from the most of the genus in having the corolla-lobes 

 sinistrorsely overlapping, instead of the contrary direction, or occasionally with 

 one lobe wholly outside and one inside, as often happens in this aestivation. 



A. Pickeringia, Torr. & Gray. Shrub 5 to 9 feet high, glabrous : leaves from ob- 

 ovate to lanceolate-oblong, glaucescent, entire (2 to 4 inches long), contracted at base into

ORDER LXXXIII. SAPOTACE.E. 



Shrubs or trees, with perfect flowers, agreeing with the foregoing order in 

 having fertile stamens of the same number as the (proper) lobes of the corolla 

 and opposite them, and inserted on its tube, in the short corolla, undivided style 

 and stigma ; differing in the few-several-celled ovary with solitary anatropous 

 or amphitropons ovules, and a comparatively large seed with a crustaceous or 

 bony testa (containing a large straight embryo with or without albumen), with 

 broad and flat or sometimes fleshy-thickened cotyledons ; and the juice in most is 

 milky. Flowers regular and small, in axillary clusters. Calyx free, of 4 to 7 

 distinct sepals, which are strongly imbricated. Corolla hypogynous, 4-7-cleft. 

 and the lobes imbricated in the bud, often with as many or twice as many acces- 

 sory internal lobes or appendages borne on the throat. Staminodia (answering 

 to series of stamens) commonly present, alternate with the true corolla-lobes and 

 sometimes in the form of sterile filaments, or squamiform, or petaloid. Filaments 

 of fertile stamens subulate or filiform, generally short : anthers oftener extrorse ; 

 the cells opening longitudinally. Fruit baccate, commonly by abortion 1 -celled 

 and 1 -seeded; when several-seeded, the bony seeds are laterally flattened and dis- 

 posed in a ring around a thickened axis. Leaves alternate, simple and entire, 

 pinnately veined, mostly coriaceous : stipules small and caducous or none. Pubes- 

 cence when present silky or tomentose, composed of malpighiaceous or stellate 

 hairs. Tropical or subtropical, except our species of Bnmelia. Fleshy fruit 

 of some edible. Juice of certain trees of the order yields gutta-percha. Seed 

 albuminous in all ours excepting Bumelia.

ORDER LXXXIV. EBENACE.E. 



Trees or shrubs, with limpid juice, alternate entire leaves, and dioaciotis or 

 polygamous (rarely completely hermaphrodite) regular flowers ; the staminate 

 with at least twice or thrice as many stamens as there are lobes to the short gamo- 

 petalous hypogynous corolla (usually convolute in the bud), and inserted on its 

 tube or base, their anthers introrse ; the pistillate flowers mostly with some im- 

 perfect stamens ; the several-celled ovary with one or two anatropous ovules 

 suspended from the summit of each cell ; the fruit a berry, maturing one or more 

 large and bony-coated seeds. These have a cartilaginous albumen, and a rather 

 small straight embryo, with foliaceous cotyledons and a mostly slender radicle. 

 Calyx persistent, often foliaceous and accrescent. Filaments short. Hypogynous 

 disk wanting. Styles as many or half as many as the cells of the ovary, 2 to 8, 

 distinct or partly united : stigmas sometimes 2-parted. Stipules none. Flowers 

 axillary, articulated with the pedicels. Wood very hard ; that of several species 

 of Diospyros furnishes ebony.-- Iliern, Mon. Eben. in Trans. Cambr. Phil. Soc. 

 xii. part i. A small order, of warm regions, nearly two thirds of the species

 maturing only 4 to 8 oblong bony flattened seeds. Flowers essentially dioecious ; 

 but the fertile flowers (commonly solitary in the axils) may have sterile stamens 

 more or less polliniferous ; the sterile flowers much smaller, usually racemose or 

 clustered, and with more numerous stamens. A large genus, widely dispersed, 

 but the greater portion Asiatic : fruit edible.

ORDER LXXXVIII. ASCLEPIADACE.E. 



Characters of Apocynacecu as to herbage and general structure of flowers and 

 fruit ; distinguished by the peculiar aggregation and cohesion of the pollen into 

 granulose or waxy masses (pollinia), one or sometimes two in each anther-cell, 

 and connected with the stigma or rather stigmatic disk in pairs or fours by means 

 of o glands or corpuscles, which alternate with the anthers. ^Estivation of the 

 corolla often valvate or nearly so. A corona (crown) of five parts or lobes 

 usually present between the corolla and the mostly monadelphous stamens, and 

 aclnate either to the one or the other. Ilypogynous disk within the stamens 

 none. Styles distinct up to the common stigmatic mass, or none. Fruit always of 

 2 follicles, or by abortion of one ovary solitary, several-many-seeded ; the seeds 

 almost always bearing a long and soft coma at the apex. Radicle superior. 

 Stems herbaceous or merely shrubby, not rarely twining. Leaves almost always 

 opposite or vvhorled, destitute of stipules. Inflorescence terminal, pseudo-axillary, 

 or sometimes axillary, cymose, often umbelliform. Bracts small or minute. The 

 tube of monadelphous filaments, commonly named gynostegium (a term which has 

 been applied also to the anther-portion), we call the column. 



PERIPLOCA GR.ECA, L., a woody climbing plant of the Old World, in ornamental culti- 

 vation, and in one or two places inclined to be spontaneous, represents the tribe or suborder 

 Periplocece, with granulose pollen loosely aggregated in two masses in each anther-cell. All 

 the American genera have a single firm-waxy pollen-mass to each anther-cell, i.e. they 

 belong to the suborder ASCLEPIADE^E. 



TRIBE I. CYNANCHE/E. Anthers tipped with an inflexed or sometimes erect 

 scarious membrane ; the polliniferous cells lower than the top of the stigma : pol- 

 linia suspended, attached in pairs (one of each adjacent cell of different anthers) to 

 the corpuscle or gland. 



* Crown (corona) or appendages to the corolla or anclrcecium none. 



1. ASTEPHANUS. Calyx destitute of glands. Corolla urceolate or short-campanulate, 

 5-clcft ; the lobes slightly and dextrorsely convolute : stamens inserted on the base of its 

 tube. Top of the stigma obtusely conical or more elevated. Follicles smooth. 



* * Crown double ; the exterior annular, interior of 5 flat fleshy or hood-like scales or 

 processes. 



2. PHILIBERTIA. Calyx minutely 5-glandular within. Corolla open-campanulate or 

 (in all ours) rotate ; the lobes dextrorsely convolute, narrowly overlapping. Exterior 

 crown a membranaceous ring adnate to the base of the corolla ; interior of 5 scales adnate 

 to the base of the usually very short stamen-tube or column. Top of stigma flat or um- 

 bonate, or with a short 2-cleft beak. Follicles rather thick, smooth, acuminate. 




86 ASCLEPIADACE.E. 



* * * Crown single, sometimes with accessory processes or denticulations alternate with 

 the anthers: calyx 5-parted, mostly small, commonly bearing some minute glandular 

 processes at base within. 



Stems erect or merely decumbent, never twining : corolla rotate, 5-parted, dextrorsely 

 valvate-convolute in the bud (the lobes obscurely or more manifestly overlapping by 

 their edges, or at least by their tips) : body of the stigma 6-angular or 5-lobed, flat- 

 topped : crown consisting of distinct cucullate or hollowed nectariferous appendages 

 (cuculli or hoods), one opposite each anther : anthers margined with mostly corneous and 

 salient wings. 



H- Hoods remote from the anthers, at the base of the long column. 



3. PODOSTIGMA. Corolla oblong-campanulate, 5-parted nearly to the 5-angular base ; 

 the lobes erect, oblong, obtuse. Hoods of the crown .short, somewhat incurved, and the 

 margins involute, forming pitcher-shaped nectariferous bodies. Column (and enclosed 

 styles) slender, almost as long as the corolla : five small processes under and alternating 

 with the short anthers. Wings of the latter widening downward to the truncate acute- 

 angled base. Follicles linear-fusiform, unarmed.

 = Hoods cristate- or corniculate- appendaged within. 



4. ANANTHERIX. Corolla reflexed in anthesis. Column under the hoods very short 

 but distinct. Hoods as long as the corolla and far longer than the anthers, ascending, 

 oblong-clavate with incurved summit, mainly solid, with narrow bilamellate ventral mar- 

 gin widening to and rounded at the summit, there enclosing a narrower and pointless 

 lamelliform crest. Anthers of membranous texture throughout ; their papery (instead 

 of corneous) wings much broadened downward and horizontally truncate at base. Cau-

 the whole very short column, spreading and arcuate-assurgent, little surpassing the an- 

 thers, slipper-shaped and the rounded apex fornicate, hollow and with a thickish fleshy 

 back, traversed (at least the upper part) by a salient crest which near the apex divides 

 the cavity. Anther-wings (corneous) narrowed at base, angulate above the middle if at 

 all. Caudicles shorter than the pyriform pollinia. Leaves commonly alternate. 



6. ASCLEPIAS. Corolla almost always reflexed in anthesis. Hoods involute or com- 

 plicate, not fornicate, bearing a horn or crest-like (pointed or rarely pointless) process 

 from the back or toward the base within, either sessile next the corolla or elevated on a 

 column which is shorter than the anthers. Corneous anther-wings widening down to the 

 base, usually triangular, the salient base being truncate or semihastate, or not rarely 

 broadly rounded. Leaves opposite, sometimes varying to alternate or vcrticillate. 



= = Hoods wholly destitute of crest or appendage within : corolla reflexed in anthesis.

ORDER XC. GENTIANACE^E. 



Herbs, with bitter colorless juice, and (the Menyanthece excepted) with opposite 

 or rarely verticillate simple and entire sessile leaves, no stipules, perfect and reg- 

 ular flower.-;, persistent calyx and often marcescent corolla, the latter (with one or 

 two exceptions) dextrorsely convolute in the bud, a one-celled free ovary with 

 two parietal many-ovuled placenta-, or the whole parietes ovulit'erous, a single style 

 with usually 2-lobed or 2-lamellate stigma, and the capsule dehiscent through the 

 placenta. Seeds indefinitely numerous, or rarely few, anatropous, commonly 

 small, and with a minute embryo in fleshy albumen. Stamens, as in all the 

 related orders, borne on the tube or base of the corolla, as many as its lobes and 

 alternate with them: anthers in our genera 2-celled and opening longitudinally. 

 Style rarely cleft, at least the divisions stigmatose down the inner face of the 

 lobes. Plants almost all glabrous and smooth throughout, and the flowers cymose 

 or simply terminal. Ovary in all our genera one-celled, or half two-celled by 

 introflexion of the placentae (in some exotic genera 2-celled). The Menyanthea 

 differ almost ordinally in the foliage and estivation. Obolaria and Bartonia are 

 remarkable for the imbricated aestivation of the corolla : the sepals of the latter 

 are reduced to two : their lower leaves or scales are often alternate. 



SUBORDER I. GENTIANEJ^. Leaves always simple and entire, sessile 

 (except some radical ones), never alternate, except in one Stverlia. ^Estivation 

 of the corolla never valvate. 



* Lobes of the corolla convolute in the bud.

 the 'divisions at first often connivent as if united, the flowers being proterandrous : 

 seeds numerous, with a close and reticulated or foveolate coat. 



H- Calyx 4-toothed and 4-angled : anthers cordate-ovate and unchanged in age.

 mostly twisting or curving in age : placenta; more or less intruded. 



2. ERYTHRJEA. Parts of the flower 5 or sometimes 4. Calyx-lobes narrow and 

 carinate. Corolla salverform with either a short or rather long tube. Filaments slender: 

 anthers oblong or linear, commonly exserted, twisting spirally in one or two turns after 

 anthesis. Style filiform : stigmas from oblong to flabelliform. Capsule from oblong-ovate 

 to fusiform. 



3. SABBATIA. Parts of the flower 5 to 12. Corolla rotate. Filaments filiform, rather 

 short : anthers linear or elongated-oblong, soon arcuate, recurved, or revolute. Style 2- 

 cleft or 2-parted; the lobes filiform, compresscd-clavate or spatulate, introrsely stigmatose 

 for most of their length. Capsule globose or ovoid, thick-coriaceous or at first fleshy.

ORDER XCI. POLEMONIACE^E. 



Herbaceous or rarely shrubby plants, with bland colorless juice, simple or di- 

 vided leaves and no stipules, perfect and regular 5-merous flowers except that 

 the free ovary is trimerous (3-celled with placentas in the axis) ; the persistent 

 calyx imbricated, and the corolla dextrorsely convolute (and not plicate) in the 

 bud ; the fruit a 3-celled loculicidal capsule, usually with a thick placental axis ; 

 the few or many seeds small, amphitropous or nearly anatropous, with a thin or 

 soft coat, commonly developing mucilage when wetted ; the embiyo straight and 

 rather large in the axis of a fleshy or harder albumen, the cotyledons flat or 

 flattish and rather broad. Stamens on the corolla alternate with its lobes, distinct. 






Phlox. POLEMONIACEJE. 129 



Style one, 3-lobed or cleft ; the introrse stigmas (or lobes of the style stigmatic 

 down the inner face) slender. Hypogynous disk generally manifest. Almost 

 exclusively American, and remarkable among the hypogynous gamopetalous 

 orders for the 3-merous pistil, but in 2 or 3 species of Gilia 2-merous. The corolla 

 is not always perfectly regular, and the o stamens are very commonly unequal in 

 length or insertion. Cobcea, common in cultivation, is very exceptional in the 

 order, climbing by tendrils belonging to pinnate leaves, and its capsule septicidal. 

 Gray, Proc. Am. Acad. viii. 247 ; Benth. & Hook. Gen. ii. 820. 



* Stamens unequally inserted on the tube of the corolla, not declined. 



1. PHLOX. Corolla strictly salverform, with slender tube and narrow orifice. Filaments 

 very short and unequally inserted : anthers mostly included. Ovules solitary or few in 

 each cell. Seed unaltered when wetted. Leaves opposite and entire. 



2. COLLOMIA. Corolla tubular-funnelform or salverform, with an open orifice, from 

 which the unequally inserted filaments commonly protrude. Ovules solitary or numerous. 

 Seed-coat developing mucilage and projecting uncoiling spiral threads (spmcles) when 

 wetted, except in one species. Leaves mostly alternate, and pinnately incised or divided. 



* * Stamens equally inserted in or below the throat or sinuses of the corolla. 



3. LCESELIA. Corolla tubular or funnelform, somewhat irregular, the limb being more 

 or less unequally cleft ; the naked filaments declined. Otherwise as Gilia. 



4. GILIA. Corolla from campanulate to funnelform and salverform, regular. Filaments 

 not declined, naked (rarely pubescent) at base. Ovules and seeds from solitary to numer- 

 ous. Leaves various. 



5. POLEMONIUM. Corolla from funnelform to nearly rotate, regular. Filaments more 

 or less declined and usually pilose-appcndaged at base, slender. Ovules and seeds few or 

 several in each cell. Calyx herbaceous, not scarious below the sinuses nor the lobes cos- 

 tate, accrescent. Leaves all alternate, pinnate or pinnately parted. 



1. PHLOX, L. (Ancient Greek name of Lychnis, from g^oi, flame.) N. 

 American herbs, or a few suffrutescent, chiefly perennials, many cultivated for 

 their ornamental blossoms. Cauline leaves sessile and opposite, or some of the 

 upper varying to alternate. Flowers cymose, showy, from blue-purple or lilac to 

 crimson and white ; the calyx narrow, and the corolla strongly convolute in the 

 bud. Most species with long filiform style about equalling or surpassing the 

 corolla-tube, but some with short included style, perhaps by dimorphism ; but 

 only in P. subulata have both forms been found in the same species. 



1. Perennial herbs of the Atlantic States, with flat (broad or narrow) leaves,

 in the axis. Seeds with a close and usually reticulated or pitted testa, and a 

 small or slender embryo in cartilaginous or firm-fleshy albumen. Scorpioid cymes 

 sometimes complete, more commonly reduced to geminate or solitary false spikes 

 or racemes (which in description may be termed spikes or racemes) ; the pedi- 

 cels bractless. Calyx o-parted, or of nearly distinct sepals. Benth. in Linn.

BORRAGINACE^E. 177 



ORDER XCIII. BORRAGINACE2E. 



Mostly scabrous or hispid-hairy plants, with watery juice, entire and alternate 

 (or partly opposite) leaves, no stipules, prevalently scorpioitl inflorescence, and 

 regular flowers (in Echium the corolla, &c., irregular), the 5 or sometimes 4 

 stamens on the tube or throat of the corolla, as many as and alternate with its 

 lobes, a single style rising between the divisions of a deeply 4-parted ovary, or 

 from the summit of an undivided one, the cells or lobes of which contain a solitary 

 ovule, the seed with little or no albumen, the embryo straight or rarely curved, 

 its radicle superior or centripetal. Flowers perfect, generally 5-merous. Calyx 

 and corolla free ; the lobes of the latter imbricated, convolute, or sometimes plicate 

 or induplicate in the bud. Ilypogynous disk usually present, but inconspicuous. 

 Pistil of 2 biovulate carpels, although seemingly of 4 and uniovulate. Ovule 

 anatropous or amphitropous. Fruit of 4 nutlets (or by abortion fewer), or a 

 drupe containing 2 to 4 nutlets or cells, rarely reduced to one. Some of the 

 first great division have serrate and even incised leaves, and are trees or shrubs, 

 of tropical or subtropical regions : these well distinguished from related orders 

 by the superior radicle. The true Borraginacece are almost all herbs, mainly of 

 temperate climates, with undivided style and even stigma, surrounded at base by 

 the four distinct divisions of the ovary. Inflorescence and its nomenclature as 

 in the preceding order. 



I. Ovary undivided (or only laterally 4-lobed) and surmounted by the style. 



TRIBE I. CORDIE^E. Style twice bifid: stigmas terminal, not annular. Fruit 

 drupaceous. Cotyledons longitudinally plicate or corrugated. Trees or shrubs, 

 with leaves sometimes dentate. 



1. CORDIA. Calyx tubular or campanulate, merely toothed or lobcd. Corolla funnel- 

 form or salverform ; the lobes and stamens sometimes more than 5. Stigmas clavate or 

 capitate. Ovary and drupe 4-celled, 4-seeded, or fewer by the abortion of some of the 

 cells and seeds of the hard stone. 



TRIBE II. EIIRETIE/E. Style once bifid or 2-parted (the divisions sometimes 

 coalescent to the top) : stigmas more or less capitate. Cotyledons plane. Trees, 

 shrubs, or low herbs. 



* Fruit drupaceous : ovules mostly amphitropous : trees or shrubs. 



2. BOURREBIA. Calyx globular or ovoid, closed in the bud, valvately splitting at the 

 summit into 2 to 5 teeth. Corolla campanulate or short-funnelform. Drupe containing 

 4 more or less separable one-seeded nutlets. 



3. EHRETIA. Calyx 5-parted or 5-cleft, imbricated or open in the bud. Corolla from 

 short-funnelform to rotate. Drupe usually containing 2 two-celled two-seeded nutlets. 



* * Fruit dry : ovules anatropous, pendulous : herbaceous or suffruticulose plants. 



4. COLDENIA. Calyx 5-parted, or in original species 4-parted; the divisions narrow. 

 Corolla short-funnelform or nearly salverform, seldom much surpassing the calyx; the 

 lobes rounded, imbricated or sometimes partly convolute in the bud. Stamens included. 

 Style 2-cleft or 2-parted. Ovary entire or laterally 4-lobed, 4-celled. Fruit separating at 

 maturity into 4 one-seeded nutlets, or by abortion fewer, or in one species by suppression 

 one-celled and one-seeded. Cotyledons thickish. Albumen none. 



TRIBE III. IIELIOTROPIE.rE. Style entire, sometimes wanting : stigma peltate- 

 annular, forming a complete ring, surmounted usually by an entire or 2-lobed (from 

 hemispherical to subulate) tip or appendage. Ovules pendulous. Seeds with a 

 straight or incurved embryo, in sparing or copious albumen. Leaves entire, rarely 

 denticulate. Inflorescence more or less scorpioid.

5. TOURNEFORTIA. Fruit drupaceous. Shrubs or woody twiners, or rarely almost 

 herbaceous. Otherwise nearly as Hdiotropium. 



6. HELIOTROPIUM. Calyx deeply 5-parted, persistent. Corolla salverform or funnel- 

 form, plaited and mostly imbricated in the bud. Stamens included : filaments short or 

 none : anthers connivent, sometimes cohering by pointed tips. Ovary 4-celled, 4-ovuled. 

 Fruit dry, 2- or 4-lobed, separating into 2 indurated 2-celled and 2-seeded closed carpels, or 

 more commonly into 4 one-seeded nutlets. Seed sometimes with rather copious albumen, 

 and, with the embryo, curved. Low herbs or undershrubs ; the flowers almost always 

 small. 



II. Ovary 4-parted (rarely 2-parted) from above into one-celled one-ovuled 

 divisions surrounding the base of the undivided (rarely 2-lobed) style: stigma 

 not annular, terminal.

 commonly ascending or erect, or when anatropous mostly pendulous. Nutlets 4 

 (or by abortion fewer), distinct, or sometimes at base united in pairs. Radicle 

 superior or centripetal. Albumen none. Chiefly herbs, with somewhat mucilagi- 

 nous watery juice and entire leaves. Flowers mostly near, but not in the axil of 

 leaves or bracts, or bractless in scorpioid so-called spikes or racemes. ^Estivation of 

 the corolla imbricated, except when otherwise indicated. (The depressed or elevated 

 disk, receptacle, or axis on which the nutlets are inserted, and from which they fall 

 away, is called the gynobase.) 



* Corolla and stamens regular : style entire, or sometimes barely 2-cleft at the very apex, 

 i Ovary only 2-parted: fruit involved in a bur-like transformed portion of the calyx. 



7. HARPAGONELLA.. Calyx at first slightly but in fruit exceedingly unequal ; three 

 of the lobes nearly distinct ; the remaining two more united, closely enwrapping the fruit, 

 and becoming cornute with 7 to 9 divergent long and uncinately glochidiate soft-spinous 

 processes, forming a bur. Ovule erect, anatropous. Nutlets one or sometimes both 

 maturing, obovoid-oblong, thin-coriaceous, very smooth, obliquely fixed by the narrowed 

 base to the small depressed gynobase. Seed filling and conformed to the nutlet, erect or 

 ascending. Radicle directed to the gynobase. Corolla, stamens, style, &c., as in 

 Pectocarija.

 extended much beyond the insertion (which is by a roundish or oblong areola or scar) : 

 seed accordingly horizontal or obliquely ascending, with radicle centripetal : but the 

 anatropous ovule (and ovary -lobes) in flower erect or ascending. (Calyx deeply 5-cleftor 

 parted, spreading or reflexed in fruit : corolla appendaged with strong fornicate processes 

 almost closing the throat : stamens short, included.) 



8. PECTOCARYA. Nutlets flat and thin (depressed-obcompressed), attached at the inner 

 end underneath to the small depressed gynobase, either winged, laciniate-bordered, or 

 pectinately setose around the thin margin ; the bristles or prickles simply uncinate at tip. 

 Style short : stigma capitate. Annuals, with minute white flowers imperfectly opposite 

 the leaves. 



9. CYNOGLOSSUM. Nutlets equally divergent, horizontal or obliquely ascending on a 

 depressed or pyramidal gynobase, turgid, wingless, all over glochidiate-muricate, mostly 

 separating (by an ovate or roundish scar at the upper end of the inner face) and carrying 

 away an exterior portion of the indurated style from below upward, by which they are 

 for a time pendulous. Stigma small, on a comparatively long style. Perennials or bien- 

 nials, with flowers in usually bractless racemes. 



H- -H- Nutlets erect and parallel with the style, or sometimes incurved, 



= Obliquely attached by more or less of the ventral face or angle, or by the base or pro- 

 longation of it, to 



a. The more or less elevated (from low-conical or globular to subulate) gynobase which 

 supports the style (and when narrow has been termed the base of the style), not stipi- 

 tate, and the scar not excavated.

 S. Europe, is given in Hooker's Flora Boreali-Americana, on the strength of a specimen re- 

 ceived from Newfoundland, to which it cannot be native, and the plant is rare in gardens,

 flowers soon lateral and scattered, a little above and partly opposite the leaf, on short at 

 length strongly recurved and rigid peduncles: body of the bur-like fruiting calyx, oblong 

 or fusiform, completely enclosing the solitary nutlet, or sometimes a pair. (Guadalupe 

 Island, off Lower California, Palmer.) Arizona, near Tucson, E. L. Greene.. The two globu- 

 lar lobes of the ovary are unilateral, on the side of the style next the enveloping calyx- 

 lobes, and distinct ; they apparently belong to different carpels, each of which wants the 

 other half. Both carpels uniovulate and alike in flower, and both, according to Bentham, 

 are sometimes fertile and enclosed together in the calyx. Sometimes one is excluded and 

 naked, but falls away without maturing.

 ample and rotate deeply 5-eleft limb and prominent crests in the throat; the ring at 

 base within bearing 10 very hirsute lobes or teeth : flowers mostly pedicelled : calyx-lobes 

 elongated and linear-lanceolate. Bnischia C'arolincnsis, Gmel. ?yst. i. 315. B. Gmelini,

 ii. 225. L. Bejariense, DC. 1. c. 79. Pine barrens, &c., Michigan to Minnesota, Virginia, 

 Florida, Texas, and Colorado. Tube of the intense orange corolla 4 or 5 lines long, the 

 outspread limb sometimes almost an inch in diameter, but often half smaller. In some 

 specimens, the stamens are inserted on the middle of the corolla and the style rises to 

 the throat ; in others, the style rises only to the middle and the stamens are in the throat. 

 * * * Corolla bright yellow, salverform ; its tube in well-developed Howers 2 to 4 times the length 



of the calyx ; the crests in the throat conspicuous and arching; the lobes undulate and more or less 



erose : later flowers cleistogeuous. Pentalophus, A. DC. 



L. angustifolium, Michx. Erect or diffusely branched from the base, a span to a foot 

 or more high, minutely scabrous-strigose and somewhat cinereous: leaves all linear: 

 flowers pedicelled, leafy-bracted, of two sorts ; the earlier and conspicuous kind with tube 

 of the corolla an inch or less in length and the rounded lobes commonly crenulate-erose ; 

 later ones, and those of more diffusely branching plants, with inconspicuous or small and 

 pale corolla, without crests in the throat, probably cleistogenous, the style shorter than the 

 nutlets ; in these the pedicels are commonly recurved in fruit : nutlets usually copiously 

 impressed-punctate, conspicuously carinate ventrally. Michx. Fl. i. 130 (the state with 

 inconspicuous flowers) ; Bebb in Am. Naturalist, vii. 691. L. linearifolium, Goldie in Edinb. 

 Phil. Jour. 1822, 319, the same state (unless possibly Goldie's plant is L. an-ense). L. brevi-

 Prodr. x. 87. Dry and sterile or sandy soil, prairies and banks of streams, Illinois and 

 Wisconsin to Saskatchewan and Dakota, soutli to Texas, and west to Utah and Arizona. 

 Root thick and deep, abounding in violet-colored dye. Glandular ring at base of corolla 

 naked. In the state with large and showy flowers, as far as known, the stamens are 

 always borne at the upper part of the tube, and the filiform style is slightly exserted : 

 but perhaps there is some heterogone-dimorphism. There are seemingly all stages 

 between these conspicuous and the cleistogenous blossoms which are produced through 

 the season. 



18. ONOSMODIUM, Michx. ('Ovoapu, and ii8os, likeness, from the re- 

 semblance to the Old-World genus Onosma.) Perennials (of the Atlantic States 

 and Mexico, &c.), rather stout and coarse, rough-hispid or hirsute; with nervose 

 or costate-veined leaves, and leafy-bracteate flowers crowded in scorpioid spikes 

 or racemes, when fruiting more separated ; the bracts resembling the leaves. 

 Fl. spring and summer, strongly proterogynous, the style early exserted. Corolla 

 greenish-white or yellowish-green: a glandular 10-lobed ring adnate to the base 

 of the tube within. Nutlets as in most Lithosperma. -- Michx. Fl. i. 132.

 rescence in age elongated, many-flowered : pedicels 4 or 5 lines long : calyx parted to the base 

 into narrow linear lobes (often an inch long) : corolla narrowly trumpet-shaped, 2 inches 

 long, whitish and densely villous outside, yellow inside ; the lobes oblong-ovate, obtuse, 

 nearly equalled by the erect anthers. Macroineria viridiflom, Torr. Bot. Mex. Bound. 139, 

 not DC., according to Ic. Mex. t. 904, which has broadly subcordate-ovate and acute corolla- 

 lobes, giving the appearance of " excised sinuses," shorter and versatile anthers, &c. New 

 Mexico, Thurber, Bigelow, Wriyht. Arizona, in dry woods, Rothrock. The portions of base 

 of the corolla lobes which are interior in the bud are roundish-auriculate. 



2. ONOSMODIUM proper. Corolla seldom twice the length of the calyx ; the 

 lobes somewhat condupiicate in the bud ; the sinuses gibbous-iuflexed : filaments 

 shorter (in our species very much shorter) than the mostly sagittate glandular- 

 mucronulate or acuminate anthers : leaves pinuately nervose-ribbed. Onos- 

 modinm, Michx. 



O. Bejariense, DC. Stems 1 to 3 feet high, rather stout, hispid with spreading bristles : 

 leaves oblong-lanceolate, 5-7-ribbed (the lower obtuse, upper acutish) ; upper surface 

 appressed strigose-hispid, the lower more or less canescent with fine and soft pubescence : 

 flowers short-pedicelled : corolla f unnelforin (6 to 9 lines long), about twice the length of 

 the calyx, white; the greenish ovate-triangular acuminate lobes about one quarter the 

 length of the tube, minutely pubescent externally and with some long hirsute hairs.

O. Carolinianum, DC., 1. c. Stout, 2 or 3 feet high, shaggy-hispid : leaves ovate-lan- 

 ceolate and oblong-lanceolate, acute, 5-9-ribbed, generally hairy both sides : flowers nearly 

 sessile : corolla short (4 or 5 lines long), yellowish-white, oblong-funnelform ; its ovate- 

 triangular acute lobes very hairy outside, and nearly half the length of the tube. Litlio-

 appressed: leaves mostly smaller (about 2 inches long), when young softly strigose-canes- 

 cent beneath. Onosmodium molle, Michx. El. i. 133, t. 15 ; Gray, Man. ed. 5, 302. Purshia 

 mollis, Lehm. Asper. 382. Illinois to Saskatchewan, Utah, and Texas. 



O. Virginianum, DC., 1- c. Strigulose-hispid throughout with mostly appressed short 

 bristly hairs : stems rather slender, a foot or two high, often paniculate : leaves narrowly 

 oblong or somewhat lanceolate, obtuse (1 to 2i inches long), 3-5-ribbed : corolla yellowish, 

 small (4 lines long) ; the lobes lanceolate-subulate, sparingly long-bristly outside, little 

 shorter than the cylindraceous tube. 0. hispidum, Michx. 1. c. Purshia hispida, Lehm. 1. c. 

 Lithospermum Virginianum, L. Hillsides and banks, New England to Florida and Louisiana. 

 The specific names conferred by Michaux on this and the preceding species were replaced 

 in the Prodromus by earlier ones under Lithospermum ; which may be agreed to, Michaux's 

 O.hispidum being far less hispid than 0. Carolinianum, and 0. molle is a misnomer except for 

 the western variety (which cannot be separated) on which Michaux's species is founded. 



19. S"YMPHYTUM, Tourn. COMFRET. (Ancient Greek and Latin 

 name.) Coarse perennial herbs ; with large and thick bitterish roots, mucilagi-

 rather soft-hirsute : cauline leaves long-decurrent on the branches, ovate-lanceolate and 

 narrower, large : corolla yellowish-white, half inch long : style exserted : nutlets wrinkled 

 or almost smooth. Escaped from gardens into moist grounds sparingly in N.Atlantic 

 States. (Nat. from Eu.)

 hairs at length pustulate at base : leaves lanceolate, undulate-margined : flowers more or 

 less racemose : corolla blue, or at first purple ; the tube not longer than calyx ; lobes barely 

 a line long. Dry waste grounds, Canada to Virginia : scarce. (Nat. from Eu.) 



21. ECHIUMj Tourn. VIPER'S BUGLOSS, BLUEWEED. (Old -Greek name, 

 from f%i$, a viper ; the shape of the nutlets likened to a snake's head.) Bien- 

 nials (or rarely shrubs), of the Old World; flowering in summer. One species 

 an introduced weed. 



E. vuLcARE, L. Rough-hispid herb, a foot or two high : leaves lanceolate, or the upper 

 linear, sessile : flowers in short lateral spikes disposed in a raceme-like thyrsus : corolla 

 almost an inch long, showy, purple changing to deep blue (rarely pale). Roadsides and

ORDER XCIV. CONVOLVULACE.E. 



Herbs or shrubs, with stems generally twining or trailing, and many with milky 

 juice ; the leaves alternate and petioled, destitute of stipules ; peduncles truly 

 axillary, 1-flowered or cymosely 3 many-flowered ; flowers regular and perfect, 

 5-merous or rarely 4-merous, except as to the gynoecium which is almost always 

 2-carpellary ; calyx mostly of distinct and imbricated sepals, persistent ; corolla 

 either plicate and the plaits convolute, or induplicate-valvate, or sometimes im- 

 bricated in the bud, the limb either lobed or entire ; stamens as many as the 

 corolla-lobes and alternate with them, usually inserted low down on the tube ; 

 hypogynous disk commonly annular and manifest ; ovary 2-celled or rarely 

 3-celled, with a pair of erect anatropous ovules in each cell, or spuriously 

 4-6-celled (each cell being more or less divided into a pair of 1-ovuled half-cells 

 by a false partition), or rarely 2-4-parted from above around the style in the 

 manner of Borracjinacece ; style single or once or twice divided ; stigmas terminal 

 or iutrorse ; fruit capsular or sometimes fleshy ; seeds comparatively large, filled 

 by a crumpled or plaited embryo involving or partly surrounded by a little muci- 

 laginous or fleshy albumen, its cotyledons ample and foliaceous, or in Cuscula 

 a spiral embryo and no cotyledons. Cuscuta moreover is leafless. Nolanece form 

 an exceptional tribe with several or many indehiscent carpels, narrow cotyledons, 

 &c., but are all South American, and connect with the following order. The 

 present large order is well distinguished from all its allies by the character of the 

 solitary or geminate seeds, size and nature of the embryo, and inferior radicle, 

 along with the usually twining or trailing growth, alternate leaves, &c. 



TRIBE I. DICHONDREJE. Ovary divided into 2 or 4 carpels or almost separate 

 lobes, surrounding a pair of basilar styles. 



1. DICHONDRA. Corolla deeply 5-cleft or 5-parted, not plicate; the lobes imbricated 

 in the bud. Filaments and anthers short. Ovary 2-parted, forming 2 indeliiscent or irreg- 

 ularly bursting utricles in fruit : styles 2 or at base united into one, filiform : stigmas 

 capitate. Seed by abortion solitary, globular, smooth. Embryo biplicate : cotyledons 

 elongated-oblong. Creeping herbs.

 filiform to subulate or ovate, when broad sometimes flattish. Stamens included. Corolla 

 from funnelform to campanulate. Capsule globose, 2-celled, or sometimes imperfectly 

 4-celled by spurious partitions between the two seeds, or by abortion 1-celled, mostly 

 2-4-valved.

 procumbent or prostrate stems, ovate or oblong obtuse leaves, more villous pubescence and 

 larger corolla, seems to be a good species, as Meissner also supposes ; but is not found on our 

 immediate borders. Dr. Torrey's plant so referred is mainly E. Arizonicus.

 diffuse, a span or two high, very leafy : leaves entire, from oblong-ovate to lanceolate, 

 sessile, 2 to 4 lines long : flowers subsessile or short-pedicelled in the upper axils, or the

8. CUSCUTA, Tourn.* DODDER. (Name said to be of Arabic derivation.) 

 Flowers 5-merous, rarely 4-merous, white or whitish, small, in loose or dense 

 cymose clusters, usually produced late in the season. Calyx cleft or parted. 

 Corolla from campanulate or somewhat urceolate to short-tubular, with the 

 mostly spreading lobes between convolute and imbricated in the bud, not 

 plicate, marcescent-persistent either at base or summit of the capsule. Sta- 

 mens inserted in the throat of the corolla above as many scale-like lacerate 

 appendages (scales) ; these rarely absent. Ovary globular, 2-celled, 4-ovuled. 

 Styles distinct, or rarely united, persistent : stigmas globose, or in Old- World 

 species filiform. Capsule 1-4-seeded, circumscissile or transversely bursting, 

 or indehiscent. Seeds large, globular, or angular by mutual pressure. Embryo 

 filiform, spirally coiled in the firm-fleshy albumen, wholly destitute of cotyledons, 

 but the apex, or plumule, often bearing a few alternate scales, germinating in the 

 soil, but not rooting in it, developing into filiform and branching annual stems 

 of a yellowish or reddish hue, which twine dextrorsely upon herbs or shrubs, 

 and become parasitic by means of suckers which penetrate the bark in contact, 

 the base soon dying away. Small scales of the same color as the stem take 

 the place of leaves and bracts. Choisy in Mem. Genev. 1841 (cited " Cusc.") &

 and anthers short : style hardly longer than ovary : corolla marcescent at base of or 

 around the 2-4-seeded capsule. From the coast at Monterey, &c., to the Sierra Nevada. 



Var. longiloba, Engelm. 1. c. Flowers' longer-pedicelled and larger (14- to 2 

 lines long) : calyx-lobes often with recurved tips : corolla-lobes often twice the length of 

 the tube : filaments and anthers more slender: styles much longer than ovary : capsule 

 mostly' 1-seeded, enveloped by the corolla. Principally S. California and Arizona. 

 -H- -H- Ovary and capsule pointed; the latter enveloped or capped by the marcescent corolla.

incomplete : styles equalling or shorter than the ovary : capsule surrounded (not covered) 

 by the marcescent corolla, mostly 1-seeded. Bot. Calif, i. 536. C. subinclusa, var. ab- 

 breviata, & C. Californica, var.? squamigera, Engelm. Cusc. 499,500. Saline or brackish 

 marshes of the Pacific coast, on Salicornia, Stueda, &c., California to Brit. Columbia, and 

 eastward to Arizona and Utah. Intermediate between the preceding and following, distin- 

 guished from the former by larger flowers and the presence of infra-stamineal scales ; 

 from the latter by less crowded flowers, more open, and of more delicate texture. 



C. subinclusa, Durand & Hilgard. Stems rather coarse : flowers sessile or short- 

 pedicelk'd, at length in large (half to full an inch thick) and compact clusters, 2-i to 3| or 4 

 lines long: calyx cupulate, fleshy ; its lobes ovate-lanceolate, overlapping, much shorter 

 than the cylindrical tube of the corolla : lobes of the corolla ovate-lanceolate, minutely 

 crenulate, much shorter than the tube : oval anthers nearly sessile : scales narrow, fringed, 

 reaching only to the middle of the tube : slender styles longer than the ovary : capsule 

 capped by the marcescent corolla, mostly 1-seeded. Jour. Acad. Pliilad. ser. 2, iii. 42, &

 pedicels, in small clusters : tube of the broadly campanulate corolla included in the round- 

 lobed denticulate calyx, and as long as its round-ovate lobes : oval anthers on very short

 Coarse stems climbing high : flowers (a line or two long) very abundant, on short pedicels in 

 globose clusters : calyx globular-cupulate, almost enclosing the corolla ; the lobes of which 

 are much shorter than the slender tube: anthers globular and almost sessile : scales short, 

 more or less dentate : seed usually solitary. This S. American and West Indian species, 

 easily known by its proportionally large calyx and small corolla, is here characterized be- 

 cause it may be looked for in South Florida.

ORDER XCV. SOLANACE.E. 



Herbs, shrubs, or even trees, commonly rank-scented, with watery juice, alternate 

 leaves and no stipules ; the inflorescence properly terminal and cymose, but 

 variously modified, sometimes scorpioid-raceoiiform in the manner of orraginace<e 

 and HydrophyUacece, the pedicels either not accompanied by bracts or not in their 

 axils; flowers perfect and regular (or only slightly irregular) and 5-4-merous ; 

 the stamens as many as and alternate with the corolla-lobes; these induplicate- 

 valvate or plicate (rarely merely imbricate) in the bud ; ovary wholly free, nor- 

 mally 2-celled with indefinitely many-ovuled axile placentae, and surmounted by 

 an undivided style : stigma entire or sometimes bihuneUar ; ovules anatropous or 

 amphitropous ; fruit either capsular or baccate ; embryo terete and incurved or 

 coiled, or sometimes almost straight, in fleshy albumen, the cotyledons rarely 

 much broader than the radicle. The leaves, although never truly opposite, are 

 often unequally geminate, so as to appear so. Obviously distinguished from Cun- 

 volvulacece by the greater number and the character of the seeds, less definitely so 

 from ScrophulariacetB by the regular flowers with isomerous stamens and plicate 

 or valvate aestivation of the corolla, and centrifugal inflorescence, but in the last 

 tribe nearly confluent with that order by the imperfection or abortion of one or 

 three of the stamens, and some obliquity and bilabiate imbrication of the limb or 

 lobes of the corolla. Nicandra has a regularly 3-5-celled ovary ; that of Lycoper- 

 sicum, &c., becomes several-celled in cultivation ; that of Datura is spuriously 

 4-celled. 



BASSOVIA? HEBEPODA, Dunal in DC. Prodr. xiii. 407, characterized from a specimen com- 

 municated to De Candolle by Teinturier of New Orleans, in fruit only, is a mere riddle. It is 

 said to resemble Bassovia Incida. 



WITHANIA MORISOXI, Dunal, 1. c., is doubtless not a Virginian or even a Mexican plant. 

 From the figure it is likely to have been \V. somnifcm, as Dunal suggested. 



TIUBE I. SOLANE^E. Corolla (mostly short) with the regular limb plicate or val- 

 vate in the bud, usually both, i.e. the sinuses or what answers to them plicate and the 

 edges of the lobes induplicate. Stamens (normally 5) all perfect. Fruit baccate 

 or at least indehiscent, sometimes nearly dry. Seeds flattened : embryo curved or 

 coiled, slender ; the semiterete cotyledons not broader than the radicle. 



* Anthers longer than their filaments, either connivent or connate into a cone or cylinder: 

 corolla rotate : calyx mostly unchanged in fruit: parts of the flower 5 or varying to 

 more, especially in cultivation. 



1. LYCOPERSICUM. Anthers connate into a pointed cone, tipped with an empty closed 

 acumination ; the cells dehiscent longitudinally down the inner face. Otherwise as in the 

 next, but leaves always pinnately compound. 



2. SOLANUM. Anthers connivent or lightly connate : the cells opening at the apex by a 

 pore or short slit, and sometimes also longitudinally dehiscent even to the base; the con- 

 nective inconspicuous or obsolete. 



* * Anthers unconnected, mostly shorter than their filaments, destitute of terminal pores, 

 dehiscent longitudinally. 



H Calyx not investing the fruit, nor much changing under it. 



3. CAPSICUM. Calyx short, either truncate or merely 5-G-dentate. Corolla rotate, 

 deeply 5-6-cleft, valvate in the bud, not plicate. Anthers oblong or somewhat cordate.

 the bud. Stamens (5) all perfect. Fruit a capsule. Seeds and embryo as in the 

 preceding tribes. 



1 1 . DATURA. Calyx prismatic or tubular, 5-toothed, in ours at length circumscissile near 

 the base, the base remaining as a peltate border under the fruit (rarely splitting length- 

 wise). Corolla funnelform, with ample spreading border 5-10-toothed, convolute-plicate 

 in the bud. Stamens included or slightly exserted : filaments long and filiform. Style 

 long: stigma bilamellar. Capsule muricate or prickly (rarely smooth), commonly firm 

 and 4-valved from the top, sometimes fleshy and bursting irregularly at the top, 2-celled ; 

 the large many-seeded placenta? projecting from the axis into the middle of the cells 

 and connected with the walls by an imperfect false partition, so that the ovary and fruit 

 are 4-celled except near the top, and the placenta? as if borne on the middle of the 

 abnormal partitions. Seeds large, reniform-orbicular. 



12. HYOSCYAMUS. Calyx urceolate or tubular-eampanulate with a 5-lobed limb, en-

1. L.YCOPEBSICUM, Tourn. TOMATO, &c. (y/i'xoj, wolf, 

 peach.) Chiefly annuals, natives of the warmer parts of America; with once 

 or twice pinnate leaves, rounded petiolulate leaflets, racemes (so called) of small 

 flowers becoming lateral or opposite the leaves, articulated pedicels reflexed in 

 fruit, and red or yellow pulpy berries, in cultivation esculent and often becoming 

 several-celled. 



L. ESCULENTUM, Mill., var. CERASIFORME. (CHERRY-TOMATO.) Annual, hirsute on the 

 branches and more or less glandular : leaves interruptedly 1-2-pinnate ; the larger leaflets 

 incised and toothed, the interposed small ones rounder and often entire : calyx little shorter 

 than the yellow corolla : inflorescence bractlcss : berry globose and even, small. L. cerasi- 

 forme, Diinal. Solatium Lycnpersicum, var., L. S. Psendn-Lympersicum, Jacq. Vinci, t. 11. 

 The normal form, probably, of the Tomato of the gardens : spontaneous on the southern 

 borders of Texas (Berlandier, &c.) : introduced from Trop. Amer. 



2. SOL.ANUM, Tourn. NIGHTSHADE, &c. (Late Latin name of Night- 

 shade, probably from solamen, solace.) Herbs or sometimes shrubs, of various 

 habit; with the leaves (as in many other genera of the order) often geminate, 

 the proper leaf being accompanied by a smaller lateral or extra-axillary (rameal) 




Solanum. SOLAXACE2E. 227 



one, and the peduncles also extra-axillary or lateral. Flowers cymose, mostly 

 after the scorpioid manner, or by unilateral suppression in appearance racemose, 

 or rarely solitary, sometimes polygamous through the abortion of the pistil of 

 many of the flowers. A vast genus, generally diffused over the temperate and 

 warmer parts of the world, but sparingly represented in North America. 



S. ViRGiNiANUM, L. (founded on Dill. Elth. t. 267, and Pluk. Aim. t. 62, fig. 3), is some 

 one of the very prickly exotic species and not of Virginian origin. 



S. MAMMOSUM, L., a West Indian species, attributed to Virginia by Linnaeus and succeed- 

 ing authors, is unknown in the country. The less hairy S. aculeatissimum may sometimes 

 have been taken for it. In Chapman's Flora a form of S. Melongena seems to represent it. 



S. TEXANUM, Dunal in DC. Prodr. xiii. 359, is probably not Texan, although raised from 

 seed said to have been coHected there. It is a plant of the Melongena (Aubergine or Egg- 

 Plant) type, and is probably S. integrifolium, Poir. (S. jEthiopicum, Jacq. Vind. t. 2, not L. ), 

 and according to Tenore his 5. Lobelii. It has a 7-8-cleft calyx, and the fruit (from a solitary 

 fertile flower) 5-10-celled. 



S. FLORIDANUM, Dunal, 1. c. 306, taken up from an imperfect specimen so named by Shut- 

 tleworth in herb. DC., collected by Rugel at St. Mark's, Florida, is not identified, is prob- 

 ably some waif of ballast ground, and, having long-hairy and retrorse-prickly stems and 

 pinnately parted leaves, cannot be a variety of S. Carolinense, to which Chapman referred it. 



1. Fruit naked, i. e. not enclosed in the accrescent calyx (in one species 

 somewhat so) : stamens all alike. 



* Tuberiferous-perennial, pinnate-leaved : anthers blunt. 



S. tuberosum, L. (POTATO-PLANT), var. boreale. Low, more or less pubescent: tubers 

 about half an inch in diameter, sending off long creeping subterranean stolons : leaflets 

 5 to 7, ovate or oval, and with only one or two interposed small ones, or sometimes none 

 at all: peduncle few-flowered: corolla blue or sometimes white, angulate-5-lobed. S. 

 Fendleri, Gray in Am. Jour. Sci. ser. 2, xxii. 285; Torr. Bot. Mex. Bound. 151. New 

 Mexico, especially in the mountains, and southward: apparently not specifically distinct 

 from the Potato-plant, which extends along the Andes to Chili and Buenos Ayres. 



S. Jamesii, Torr. Low, a span or so in height : leaflets 5 to 9, varying from lanceolate 

 to ovate-oblong, smoothish ; the lowest sometimes much smaller, but no interposed small 

 ones: peduncle cymosely few-several-flowered: corolla white, at length deeply 5-clef t : 

 otherwise as in the last. Ann. Lye. N. Y. ii. 227; Gray, 1. c. Mountains of Colorado 

 to New Mexico and Arizona. (Mexico, probably under several names.) Seems on the 

 whole distinct ; but Fendler's no. 669 belongs here, at least in part. 



* * Annuals (at least in our climate), simple-leaved, never prickly, but the angles of the stem 

 sometimes minutely denticulate-asperate : anthers blunt: pubescence when present simple: 

 flowers and globose berries small. 



-I Leaves deeply pinnatificl. 



S. triflorum, Nutt. Green, slightly hairy or nearly glabrous, low and much spreading : 

 leaves oblong and pinnatifid, with wide rounded sinuses ; the lobes 7 to 9, lanceolate, 3 or 

 4 lines long, entire or sometimes 1-2-toothed : peduncles lateral, 1-3-flowered : pedicels nod- 

 ding : corolla small, white, a little longer than the 5-parted calyx : berries green, as large 

 as a small cherry. Gen. i. 128. Plains from Saskatchewan to New Mexico, chiefly as a 

 weed near habitations and in cultivated ground. 



-i -) Leaves varying from coarsely toothed to entire: flowers in small pedunculate umbel-like 

 lateral cymes : corolla white and sometimes bluish : berries usually black when ripe, rarely red or 

 yellowish, only as large as peas. (Section Morella, Dunal. ) 



S. nigrurn, L. Low, green and almost glabrous, or the younger parts pubescent : 

 leaves mostly ovate with a cuneate base, irregularly sinuate-toothed, repand, or some- 

 times entire, acute or acuminate : calyx much shorter than the corolla. Includes many 

 and perhaps most of the 50 and more species of Dunal in the Prodromus, weeds or weedy 

 plants, widely diffused over the world, especially the warmer portions. A. Braun's charac- 

 ters for several species, founded on the hairiness or smoothness of the filaments, length 

 of the anthers and of the style, and whether the calyx is loosely appressed to the ripe 

 berry or reflexed, do not hold out. Our common form, the true S. niyrum, has corolla only

3 or 4 lines in diameter, filaments more or less hairy inside, style little if at all projecting, 

 and fruiting calyx merely spreading. To this belongs mainly the following, referred to N. 

 America by Dunal : viz. S. pterocaido,T)uim\. (Dill. Elth. t. 275, fig. 356), S. crenato-dentatiun, 

 ptycanthum, and probably inops, DC. Common in damp or shady, especially cultivated and 

 waste grounds, appearing as if introduced. (Cosmopolite.) 



Var. VII.LUSUM, Mill. Low, somewhat viscid-pubescent or villous : leaves conspicu- 

 ously angulate-dentate, small: filaments glabrous to the base: berries yellow. 5. vll- 

 losum, Lam. Ballast-grounds, Philadelphia, &c. Var. ALATUM (S. alatum, Moench, S. 

 mimatum, Benth.), a similar form, but with angled brandies and red berries, has reached the 

 shores of San Francisco Bay, California. ( Adventive from S. Eu.) 



Var. Dillenii. Taller and leaves mostly entire or merely repand : filaments more or 

 less bearded, at least at the base : style exserted or sometimes not exceeding the stamens. 

 -Dill. 1. c. fig. 355. S. Dillenii, Schult, Dunal, 1. c. ; A. Braun, Ind. Sem. Hort. Berol. 

 1853. Florida to S. America. Entire-leaved forms differ from the next only in the hairy 

 filaments. S. Americanum, Mill. Diet., with glabrous leaves, should be the same, but S. 

 Besseri, Weinm., to which Dunal refers it, is a canescently-puberulent variety, with rather 

 large and entire leaves. (S. American.) 



Var. nodi9.6ru.in. Slender, of ten tall : leaves entire, rarely few-toothed, acuminate : 

 filaments glabrous : style generally exsertt d : calyx in fruit reflexed. S. nodiflorum, Jacq.

 nearly so : corolla white or bluish (about 5 lines in diameter) : filaments slightly hairy 

 inside : style exserted beyond the anthers : stigma rather large : calyx somewhat appressed 

 to the (black) berry. Hort. Berol.; Dunal, 1. c. 54, not Sendt. Coast of N. Carolina, 

 Curtis. Ballast-grounds near Philadelphia. (Nat. or adv. from Extra-trop. S. Amer.)

 cordate, some with an auriculate lobe on one or both sides at base, which are sometimes 

 nearly separated into small leaflets: corolla half inch in diameter: berry oval. Curt.

 4 inches long, and the violet corolla fully an inch and a half in diameter : branches and 

 the forking cyme villous. Island of Santa Catalina off San Pedro, California, Wallace. 

 (Coulter's no. 586, without flowers, may be a glabrous form of this.)

3. CAPSICUM, Tourn. CAYENNE PKPPER. (Name conjectured to come 

 from x7mo, to gulp down, alluding to the pungency of the fruit used as a con-

 maturity and almost capsular.) Herbs or shrubs, originally all American and 

 nearly all tropical, green and commonly glabrous ; with many-times forking stems, 

 ovate and entire or merely repand thin and usually acuminate leaves, and small 

 solitary or cymose flowers on slender (or when the fruit is recurved stouter)

 shorter than the flower : calyx-lobes lanceolate, obtuse, rather shorter than the corolla, 

 about the length of the globose berry, loose : corolla 3 lines long, narrow, apparently 

 cylindraceous, blue or purplish; the sinuses deeply induplicate in the bud: filaments 

 somewhat hairy, inclined to be unequal in length ; the longer ones and the filiform style 

 nearly equalling the corolla : seeds orbicular, flattened, foveolate-reticulated. Bot. King,

6. CHAM^ESARACHA, Gray. (Saracha is a tropical American genus, 

 dedicated by Ruiz & Pavon to Isidore Saracha, a Spanish Benedictine : the prefix

 P. viscosa, Gray, Man., not L. Light or sandy soils, Upper Canada to Florida and Texas. 

 This early name of Miller, taken up for the present species in Proc. Am. Acad. 1. c., must 

 from the size of the flower belong to it, or to a broad-leaved and hairy form of P. lanccoluta. 

 Miller's remark that " the root does not creep in the ground," is most applicable to the 

 latter ; but the color as well as size of the corolla and the " pale yellow " fruit, also the 

 diffuse growth, best accord with this common species.

 place of J-P.WTT/V, the mouth of the windpipe, the throat of corolla being narrow.) 

 Extra-tropical S. American herbs, resembling Nierembergia (which has 5 fer- 

 tile stamens borne at and exserted from the orifice of the open saucer-shaped 

 limb), but with tubular-funnelform throat, in the lower part or base of which the 

 didynamous stamens are inserted. Besides the genuine species, a Texan and a 

 Mexican species constitute a subgenus, 



1. BRACHYGLOSSIS, with strictly salverform corolla of Nierembergia ; the 

 long and filiform tube abruptly saccate-dilated just under the ample rotate limb : 

 stigma rather narrowly 2-lobed, and the lobes alate-decurrent on the apex of the 

 style : habit and foliage of Bouclietia. Gray, Proc. Am. Acad. xii. 1G4. 



L. Texana, Gray, 1- c- Low perennial, diffusely much branched from a suffrutescent 

 base, a span high, viscid-pubescent: leaves spatulate-obovate or oblong, acute (half inch 

 long), narrowed at base, the lower into a short margined petiole : peduncles mostly shorter 

 than the eampanulate-funnelform 5-toothed calyx (the teeth deltoid) : corolla apparently 

 white ; the filiform tube 8 or 9 lines long; the almost regular broadly 5-lobed plane limb 

 of about the same diameter ; the very short campanulate throat hardly over a line in

 half the length of the 10-nerved calyx: seeds somewhat reniform, coarsely transverse- 

 rugose, otherwise smooth. Nierembergia (Leptoglossis) viscosa, Browallia (Lpptoylossis)

ORDER XCVI. SCROPHULARIACE.E. 



Herbs, shrubs, or rarely small trees, with leaves either alternate or opposite 

 and destitute of stipules, primary inflorescence centripetal and the secondary when 

 developed centrifugal, perfect flowers with the bilabiately irregular corolla (5) 

 imbricated and not plicate in the bud, didynamous or diandrous stamens, 2-celled 

 ovary with axile several-many-ovuled placentae, usually capsular fruit, and ana- 

 tropous or amphitropous seeds (generally numerous), with a small and straight or 

 only slightly curved embryo in fleshy albumen, the cotyledons little if at all 

 broader than the radicle. The calyx and corolla are mostly 5-merous, and the 

 former persistent ; but sometimes they are 4-merous, at least apparently, and

either with or without all four stamens present ; sometimes the corolla is nearly 

 or quite regular, and even with all five stamens present and complete (uniformly 

 so in Verbascum, abnormally in several species of Pentstemon} ; and the ovules 

 are sometimes few and definite, rarely solitary. The posterior or superior stamen 

 is the deficient or abortive one. Corolla wanting in one Synthyris. Style one 

 and undivided : stigma either entire, or 2-lobed, or bilamellar (bilabiate) ; its lobes 

 and the cells of the ovary anterior and posterior. Seeds comparatively small, 

 rarely winged. -=- This large order has its tribes arranged by Bentham and Hooker 

 (Gen. ii. 915) under three series, hardly to be regarded as suborders, the first of 

 which closely connects with the preceding order, except as to inflorescence. The 

 ambiguous SalpiglossidecB are referred to that order. 



I. (PsEunosoLANE^E.) Leaves all alternate. Inflorescence simply centri- 

 petal. Corolla hardly if at all bilabiate ; the 2 posterior lobes external in the 

 bud. All five stamens sometimes present and perfect.

 5 rounded and spreading nearly equal lobes. Stamens 4 and didynamous, or rarely 5 and 

 the fifth imperfect, included : anthers with cells confluent at the apex, at length divari- 

 cate. Stigma emarginate or bilamellar. Capsule 2-valved, and the valves at length 2- 

 cleft. Tomentose shrubs.

 external in the bud, with a few occasional and irregular exceptions. Fertile 

 stamens very seldom more than four. 



TRIBE III. ANTIRRHINEyE. Corolla bilabiate and more or less tubular; the base 

 of the tube gibbous or saccate or spurred on the lower side, and the lower lip often

 racemose, or the flowers solitary and axillary. 



* Stamens 4, with more or less 2-celled fertile anthers. 



3. LINARIA. Corolla with a spur at base (this rarely abortive) and a prominent palate 

 nearly closing the throat. In the occasional monstrosity called Peloria, the corolla be- 

 comes regular by the production of 5 spurs and 5 regular short lobes.

 Linaria, or the palate in some species much less prominent. Seeds destitute of any proper 

 wing.

perianth, with didynamous stamens and the dimerous pistil of all the related 

 orders, but the stigmas and the placentae sometimes divided or separated so as 

 apparently to 1)6 four : all the flower commonly marcescent-persisteut. Corolla 

 ringent. Anthers always 2-celled. Ovary ovoid, pointed with a mostly long 

 style: stigma sometimes peltate or disc-shaped and entire, often bilabiate, occa- 

 sionally 4-lobed, i. e. the anterior and posterior stigma each 2-lobed, and some- 

 times these lobes or half-stigmas combine laterally, forming two right and left 

 stigmas which therefore are superposed to (instead of alternate with) the parietal 

 placentae When the latter are four, it is because the half-placentae are borne 

 more or less within the margin of each carpel. Capsule 2-valved, each valve 

 bearing on its face a single placenta or a pair. Hypogynous gland not rarely at 

 the base of the ovary on one side. Flowers solitary in the axils of bracts or 

 scales, sometimes on scapiform peduncles, sometimes collected in a terminal spike : 

 evolution always centripetal.

ORDER XCVIII. LENTIBULARIACE^E. 



Herbs, growing in water or wet soil, when terrestrial acaulescent, with scapes 

 or scapiform peduncles simple and one-few-flowered, calcarate corolla always 

 and calyx usually bilabiate, a single (anterior) pair of stamens, confiuently one- 

 celled anthers contiguous under the broad stigma, no hypogynous disk, and a free 

 one-celled ovary with free central rnultiovulate placenta (either sessile or stipi- 

 tate) which becomes a globular many-seeded capsule ; the anatropous seeds with 

 a close coat, no albumen, and filled by the apparently solid ellipsoidal or oblong 

 embryo. Style short or none : stigma bilamellar, or the smaller anterior lip 

 sometimes obsolete. Upper lip of the corolla commonly erect or concave, or the 

 sides replicate, from entire to 2-lobed, interior in the bud ; lower larger, spreading 

 or reflexed, 3-lobed, with a palate projecting into the throat and a nectariferous 

 spur beneath. Flowers always perfect. Capsule commonly bursting irregularly. 

 The following are the two principal genera. (For action of bladders of Utri- 

 cularia and leaves of Pinguicula, see Darwin, Insectivorous Plants, p. 368-453.) 



1. UTRICULARIA. Calyx 2-parted or deeply 2-lobed ; lobes mostly entire, nearly equal. 

 Upper lip of strongly bilabiate and more or less personate corolla erect. Filaments thick, 

 strongly arcuate-incurved, the base and apex contiguous. Dissected foliage or stems of 

 aquatic species bladder-bearing. 



2. PINGUICULA. Calyx with upper lip deeply 3- and lower 2-cleft or parted. Corolla 

 ringent or less personate, and the lobes all spreading. Filaments straightcr : anthers nearly 

 transverse. Terrestrial, with entire rosulate leaves next the ground. 



1. UTRICULARIA, L. BLADDERWORT. (Utriculus, a little bladder.) 

 - Cosmopolitan small herbs : terrestrial species with inconspicuous or fugacious 

 radical leaves ; aquatic with the dissected leaves, branches, and even roots, bearing 

 little bladders, which are furnished with a valvular lid, and commonly tipped with 

 a few bristles at orifice. Scapes one-flowered or racemosely several-flowered, in 

 summer. Lentibularia, Vaill. 



1. Scape bearing an involucriform whorl of dissected leaves, which are buoyant 

 by ample inflated-bladdery petioles filled with air : cauline leaves of the immersed 

 branching stems capillary-dissected and bladder-bearing, in the manner of the fol- 

 lowing section : roots few or none.

 some or many of them (as also stems) bearing small bladders : chiefly perennial, 

 or continued by hybernacular tuber-like buds set free in autumn. 



* Ck'istogamous flowers along the submersed copiously bladder-bearing stems. 



U. dandestina, Nutt. Leaves of the slender stems repeatedly forked : scapes slender, 

 3 to 5 inches high, 3-5-flowered: corolla yellow, 3 lines long; lips nearly equal in length,

 rising from or producing filiform and root-like creeping shoots, which bear slender 

 subulate-gramineous (occasionally septate) simple leaves, or branches which take 

 the place of leaves, to the lower part of which, as also to the colorless shoots, 

 bladders are sparingly attached, usually fugacious or unnoticed, so that the flower-

ORDER XCIX. BIGNONIACE^E. 



Trees or shrubs, either erect or scandent (very rarely herbs), with mostly oppo- 

 site leaves, and large and showy flowers, with more or less bilabiate corolla, tetra- 

 dynamous or diandrous stamens, single style and bilabiate stigma, and numerous 

 anatropous ovules of the preceding orders ; distinguished from them by the large 

 and flat usually winged and transverse exalbuminous seeds, indefinitely numerous, 

 on parietal placentae, or usually on a partition which separates from the two valves 

 of the capsule in dehiscence, although in the ovary and when the ovules are in 

 many rows the placeutation often appears to be central ; the cotyledons broad 

 and thin, plane, commonly emarginate or 2-lobed, and the short straight radicle 

 included in the basal notch. Capsule either loculicidal or septicidal, often silique- 

 like. Anthers 2-celled : suppressed stamens commonly represented by rudimen- 

 tary filaments. Corolla bilabiately imbricated in the bud (in our genera, in a few 

 others valvate). Calyx gamosepalous. Leaves compound, or in two of our genera 

 simple ; sometimes a pair of basal leaflets and sometimes an axillary pair of leaves 

 imitate stipules. Chiefly a tropical and rather large order ; but few North 

 American.

 in a single series on each side of both margins of the partition ; the thin wing entire. Ten- 

 dril-climbers. 



2. TECOMA. Calyx distinctly 5-toothed. Corolla funnelform or somewhat campanulate 

 above the short proper tube, somewhat bilabiately 5-lobed. Anther-cells divergent,

 parietal intruded placenta; expanded into two broad lamellte or united into a 

 central columella, or variously 2-4-celled by the extension of the placentae and by 

 spurious partitions from the wall. Fruit capsular, drupaceous, or nucumentaceous, 

 few-many-seeded. Seeds wingless, mostly with a thick and close coat, filled by 

 the large embryo ; the cotyledons thickish. A small extra-European and mainly 

 African order, or suborder, of warm climates, represented in the United States by 

 one sparingly naturalized, and one or two probably indigenous species.

 the inflorescence puberulent, with also some short-stipitate glands. W. Texas, Buckley. 



2. Anomalous species, cinereous-pubescent: flowers small, in the axils of 

 ordinary leaves and in slender spikes terminating the branches. (D. Sayrceana,

 Chiefly herbs, dispersed over the warmer regions of the world. Fl. summer. 

 Corolla often seemingly resupinate as relates to primary axis, on account of the 

 cymose inflorescence or the evolution of more than one flower in the involucre.

 only species. 



ORDER CIV. LABIATE. 



Herbs or low shrubs, with aromatic herbage (usually dotted with small im- 

 mersed glands replete with volatile oil), with square stems, opposite simple leaves 

 and no stipules ; the perfect flowers with irregular more or less bilabiate corolla, 

 didynamous or diandrous ; filiform style mostly 2-cleft and 2-stignmtose at apex, 

 and around its base the divisions of a 4-parted (sometimes only 4-lobed) ovary, 

 which are uniovulate and ripen into akene-like nutlets, in the bottom of a gamo- 

 sepalous calyx. Ovule and seed mostly amphitropous or anatropous, and erect. 

 Embryo straight except in the Scutellarinece, with plane or plano-convex coty- 

 ledons and inferior radicle : albumen usually none or hardly any. Lobes of the 

 corolla imbricated in the bud, the posterior or the upper lip exterior and the 

 middle lobe of the lower lip innermost. Stamens borne on the tube of the corolla, 

 distinct or rarely monadelphous ; the fifth (posterior) stamen, and in diandrous 

 flowers the adjacent pair also, not rarely represented by sterile filaments or rudi- 

 ments : rarely the 4 fertile stamens equal. Hypogynous disk generally present, 

 sometimes as (one to four) gland-like lobes. Pistil as in all the related orders 

 dimerous, each carpel deeply 2-parted or 2-lobed. Inflorescence thyrsoidal ; the 

 general evolution of the clusters in the axils of leaves or primary bracts (these 

 occasionally reduced to single flowers) centripetal ; that of the clusters (cymes or 

 glomerules) centrifugal. The pair of sessile clusters, one to each axil, having 

 the appearance of a whorl (verticil) form what has been termed a verticillaster. 

 Bracts or bractlets various. Leaves occasionally verticillate. Seed transverse 

 and the radicle incurved in Scutellarineee. (The Ajngoidc.a> connect with the 

 tribe ViticecB of the preceding order, and therefore are placed foremost. A 

 larger proportion of our Labiatce are Old Woild naturalized plants than of 

 any other order.) Benth. Lab. & in DC. Prodr. xii. 26 ; Benth. & Hook. Gen.

ORDER CV. PLANTAGINACE.E. 



An anomalous order of Gamopetalce, chiefly acaulescent herbs with one-several- 

 ribbed or nerved radical leaves, simply spicate inflorescence, and regular 4-merous 

 flowers having a free ovary, a filiform and entire long-stigmatose style, amphi- 

 tropous and peltate ovules and seeds, a mostly straight embryo in firm-fleshy 

 albumen, the cotyledons little broader than the radicle, and the corolla scarious 




Mantago. PLANT AGINACE.E. 389 



and veinhss, mostly marcescent-persistent. Consists chiefly of the two following 

 genera ; the principal genus of many species and widely dispersed over the 

 world, but most largely European and Asiatic ; the other of a single species 

 widely dissevered in habitation. 



1. PLANTAGO, Tourn. PLANTAIN, RIBWORT. (The Latin name.) 

 Flowers perfect or polygamo-dicecious, each subtended by a bract. Calyx of 

 4 imbricated sepals, persistent. Corolla salverform with a short tube, or nearly 

 rotate ; limb 4-parted ; lobes imbricated in the bud, two lateral exterior. Stamens 

 4, or sometimes 2, on the tube of the corolla: filaments commonly capillary: 

 anthers 2-celled, versatile. Ovary 2-celled (or rarely falsely 3-4-celled), with one 

 or more ovules in each cell. Style or stigma mostly hairy. Capsule (pyxidium) 

 circumscissile toward the base, and with a loose partition falling away with the 

 lid ; the seeds attached to its face. Seed-coat developing copious mucilage 

 when wetted. Scape from the axils of the radical or subradical leaves, mostly 

 bearing a single simple spike or head of greenish or whitish small flowers, in 

 summer. 



1. Stamens 4: flowers all perfect: corolla not closed over the fruit. 



* Flowers dichogamous, proterogynous; the style projecting from the apex of the unopened 

 corolla; the anthers long-exserted on capillary filaments after the corolla has expanded. 



-1 Corolla glabrous (as also the whole inflorescence, except in P. macrocarpa) : seeds not hollowed 

 (or barely concave) on the inner face: leaves 3-8-nerved or ribbed, plane: root perennial. 



-H- Ribs or nerves of the broad leaves mainly confluent with the thick and dilated lower portion of 

 the midrib: ovules only 2 in each cell: seeds by abortion sometimes solitary. 



P. COrdata, Lam. Very smooth : leaves cordate or ovate (3 to 8 inches long), sometimes 

 repaud-dentate, loiig-petioled, 7-9-ribbed : scape fistulous, stout, a foot or two high, includ- 

 ing the narrow spike : bracts rotund-ovate, very obtuse, as are the ovate and obovate sepals 

 and the corolla-lobes : capsules broadly ovoid, twice the length of the calyx : seeds 4 to 2, 

 large, oblong. 111. i. 338 ; Jacq. Eclog. t. 72. P. Kentiwkensis, Michx. Fl. i. 94. Along

= Leaves ovate or oval, or in small forms oblong, rarely subcovdate, several-ribbed, base abruptly 

 contracted into a distinct petiole, not fleshy, glabrous' or pubescent, from entire to sparingly re- 

 pand-dentate: ovules and seeds at least 2 in each cell: scapes with the spike a span to 2 feet high. 



P. major, L. (COMMON PLANTAIN.) Spike commonly dense, obtuse at apex: sepals 

 rotund-ovate or obovate, scarious-margined ; the exterior and the bract more or less cari- 

 nate : ovules 8 to 18 : seeds as many or by abortion fewer, small, angled by mutual press- 

 ure, Visually light brown, minutely reticulated : capsule ovoid, very obtuse, circumscissile 

 near the middle and near the level of the summit of the sepals. -- Waysides and near 

 dwellings throughout the country, doubtless introduced from Europe, but also native from 

 Lake Superior far northward. Runs into some monstrosities and several varieties, an 

 extreme in saline soil being var. minima, Decaisne in DC. Prodr. xiii. 695 (P. minima, DC.), 

 with scapes 2 to 5 inches high, and leaves proportionally small. (Cosmop.)

SUPPLEMENT TO VOL. II. PAPtT I. 



ADDITIONS AND CORRECTIONS. 

 LOBELIACE^E. 



The following are additions and corrections to the generic characters of this 

 order, on p. 2 : 



I. NEMACLADUS. Filaments either partly or almost wholly monadelphous. Seeds oval 

 or globular, obscurely costate or striate longitudinally and somewhat favose or transversely 

 reticulate between the ribs. 



I I . PARISHELLA. Calyx 5-cleft, with campanulate tube wholly adnate to the ovary and 

 shorter than the spatulate foliaceous lobes. Corolla almost rotate, shorter than the calyx, 

 deeply and nearly equally 5-cleft. Stamens free from the corolla : filaments distinct at base 

 only, above connate into a slender tube with inflexed summit. Style filiform : stigma de- 

 pressed-capitate, 2-lobed, not annulate. Capsule turbinate, inferior, except the low-conical 

 apex, which is circumscissile close to the base of the calyx-lobes and falls off as a lid. Seeds 

 globose, smooth and nearly even. Otherwise nearly as Nemucladus. 



I 2 . HOWELLIA. (Under tribe Lobeliea'.) Flowers of two forms ; the emersed corolliferous, 

 submersed with undeveloped corolla. Calyx with linear-clavate tube adnate for its whole 

 length to the ovary, and a limb of five nearly equal slender-subulate or filiform segments. 

 Corolla even iu emersed flowers not surpassing the calyx ; its very short tube divided nearly 

 to base on the (apparently) upper side ; lobes oblong, almost equal, three united higher. 

 Stamen-tube nearly free, and with the included style slightly incurved : anthers oval ; two 

 smaller trisetulose, three larger naked. Ovary strictly one-celled, with two filiform parietal 

 placentae, each 3-5-ovulate. Upper ovules ascending ; lower pendulous. Capsule clavate- 

 obloug or fusiform, with contracted apex, membranaceous at maturity and bursting irregu- 

 larly on one side. Seeds few and large, linear-oblong, smooth, callous-apiculate at the 

 chalaza. Aquatic herb. 



1. NEMACLADUS, Nutt. Genus now increased in number of species 

 and forms. 



N. ramosissimus, NUTT., p. 3. Rarely a little puberuleut : filaments usually monadel- 

 phous for most of their length, sometimes separating below in age. Nuttall's original is 

 the more slender and verv diffuse form, most abundant in Lower California, W. Arizona,

 and San Bernardino Co. to Lower California. An interesting addition to the generic char- 

 acter, detected by Mr. Nevin, is that the throat of the corolla on the (apparently) upper side 

 bears a nectary, as if an adnate spur, forming a narrow imperfectly tubular cavity, reaching 

 down to the insertion of the filament-tube on that side.

V. OxycoCCUS, L., p. 25. To the slender and chiefly high-northern form of this belongs 

 Oxi/coccos microcarpa, Turcz. Fl. Baic.-Dahur. ii. 195. To this (as being the original 

 species), rather than to V. macrocarpon, is referred the connecting form of the Pacific 

 coasts, viz. : 



Var. intermedium. Leaves from ovate to oblong, mostly obtuse, a third to half 

 inch long : flowers strictly umbellate from the scaly bud, but this not rarely proliferous into 

 a leafy shoot (in the original of the species very rarely so) : berry 4 or 5 lines in diameter. 

 Washington Territory and N. Oregon, Suksdorf, Henderson. Also, doubtless, Douglas, in 

 Hook. Fl. ii. 35, referred to V. macrocarpon, very naturally, as leaves of the specimen are 

 elliptical, obloug, very obtuse, even more so at apex than base, obviously veiny beneath, and 

 margins hardly at all revolute. (N. E. Asia, Sachalin, Japan, &c.) 



V. macrocarpon, Ait., p. 26. Pedicels becoming scattered along the base of a leafy shoot 

 proliferous from the scaly bud, either squamaceous- or leafy-bracted. 



4. ARBUTUS, Tourn. P. 27, add: 



A. LAVRIFOLTA L. f. The original of this is probably a specimen of A. Unedo (doubtless 

 of the Old World), in the herbarium of Linnanis, on which Smith has written this name. 

 The A. Iqurifolia, Lincll. Bot. Keg. xxv. t. 67, is surely A. Xalapensis, HBK., a variable Mexican 

 species. The North American forms, other than the A. Menziesii of the Pacific coast, are very 

 difficult, but seem to be best disposed as follows : 

 A. Xala/pensis, HBK., var. Arizonica. Tree 20 to 40 feet high, with a whitish and 



thickish scaly bark on the main trunk, but with the reddish close and thin bark of A . Men-

5. ARCTOSTAPHYLOS, Adans. 



A. nummularia, GRAY, p. 28. This grows 2 to 6 feet high, has been collected on the 

 Mendocino plains by Pringle, and near Santa Cruz by Anderson, by the latter with fruit ; an 

 oblong drupe, only 2 lines long, the thin pulp dry at maturity, and the whole splitting 

 up into the (mostly 4) thin-shelled nutlets. On this account, Parry, in monograph of 

 Arctostaphylos, in Proc. Davenport Acad. Nat. Sci. iv. 30, makes this the type of a new 

 section, Micrococcus. 



A. bicolor, GRAY, p. 29. Add syn. : A. Veatchii, Kellogg, Proc. Calif. Acad. ii. 19. Also 

 A. Cleveland!, p. 29, & Proc. Am. Acad. xii. 61, appears to be an abnormal and autumn-

 branches mostly spatulate-lanceolate, entire or spinulose-serrulate ; of sterile shoots oblong or 

 oval, either finely -or coarsely spinulose-deutate : racemes solitary or clustered, loose : bracts 

 lanceolate-subulate : calyx 5-parted into subulate divisions : corolla ovate : filaments long- 

 bearded at base : drupe only 2 lines in diameter and with solid 5-celled putamen. A. arguta,

A. oppositifolia, PARRY. An anomalous species : leaves opposite or in threes, linear, 

 entire, with revolute margins, much resembling those of Andromeda polifolia : flowers pa-

398 SUPPLEMENT. 



17. RHODODENDRON, L. P. 41, after fi. Ehodora, add : 



R. Vaseyi, GRAY. Shrub 5 to 15 feet high, nearly glabrous : branchlets wholly destitute of 

 strigose bristles : flowers rather preceding the leaves, from few-scaled buds : leaves obloug, 

 acute or acuminate at both ends, sparsely hirsute, at least the midrib and margins when 

 young, when adult 3 to 5 inches long and 1 or 2 wide : corolla pale rose-color, rotate- 

 campanulate, but irregular, somewhat unequally 5-parted ; upper lobes shorter and overlap- 

 ping, somewhat spotted, three lower diverging and widely spreading, all broadly obovate : 

 stamens 5 to 7, commonly 7 : capsule minutely glandular, oblong, acutish. Proc. Am. 

 Acad. xv. 48. Mountains of Jackson Co., N. Carolina, " seven miles southwest of Webster," 

 George R. Vasey, and Chimneytop Gap, Donnell Smith, flowering in May. Nearest R. Al- 

 brechtii of Japan. Requires some extension of the Rhodora subsection. 



R. Californicum, HOOK., p. 41. Extends north to Brit. Columbia; and the syn. R. 

 maximum, Hook. Fl., as to the Pacific coast plant, belongs in part, if not wholly, here. 



R. macrophyllum, DON, p. 42. This is not yet well made out ; but it was originally 

 described (from the collection of Menzies) as having corolla smaller than of R. maximum, 

 and white, and leaves large. It should therefore be to R. Californicum what R. maximum is 

 to R. Catawbiense. But it is doubtful if there are two true species on the Pacific coast. 



31. SCHWEINlTZIA, Ell. Two species, characterized thus : 



S. Odorata, ELL., p. 49. Scales of the stem broadly ovate, imbricating : flowers in a short 

 spike, hardly nodding : sepals oblong, about equalling the flesh-colored corolla. Gray, 

 Proc. Am. Acad. xx. 301. 



S. Reynoldsise, GRAY, 1. c. More slender, with smaller and remoter scales : flowers more 

 numerous and smaller, slightly fragrant, soon nodding and mostly secuud in the narrow 

 spike: sepals ovate or lanceolate, half the length of the white corolla. E. Florida 

 near the coast, on Indian River, &c , first found by Miss Mart/ C. Reynolds, flowering in 

 winter. 



33. PLEURICO" SPORA, Gray. P. 50 and 18, add : No hypogynous 

 disk-glands. Placentas apparently double the petals in number, commonly 8.

 linear. Disk of short and deflexed glands alternating with the stamens, Kow 

 two species : 



N. congesta, Torr., p. 50. Flowers densely crowded in a corymbiform glomerule : lobes of 

 the corolla ovate, one third the length of the cylindraceous or slightly urceolate tube: fila-

 the connective: cauline scales ovate, obtuse, only slightly erose. Gray, Proc. Am. Acad. 

 xv. 44. Besides Dr. Newberry's original specimens in the Cascade Mountains of Oregon, 

 now found in coniferous forests of Mad River, N. W. California, Rattan. 



N. spicata, GRAY, 1. c. Flowers spicately crowded : corolla more campanulate, with oblong 

 lobes half the length of the tube : filaments not equalling the short style : anthers short- 

 oblong, the line of dehiscence somewhat remote from the connective : cauline scales narrowly 

 oblong, acutish, fimbriate-erose. Woods, in the mountains of Humboldt Co., California,

 rosulate radical or simply proliferous clusters : flowers in 2-5-rayed pedunculate umbels : 

 bracts of the involucre oval or ovate, short : corolla-tube almost twice the length of 

 the calvx. Proc. Am. Acad. xvi. 105. Mountains of Oregon, Hoicell, Mrs. Barrett,

ASCLEPIADACE^E. 



The synoptical characters of the genera, on p. 85 and p. 87, to be augmented 

 as follows : 



5. ASCLEPIODORA. To character of hoods, add : At the sinuses between them are 

 auriculate lobes, alternate with the anthers, simulating an inner corona. 



141. ROTHROCKIA. Corolla rotate, deeply 5-cleft ; the lobes oblong, dextrorsely over- 

 lapping in the bud. Crown simple, inserted at the junction of corolla and stamen-tube, 

 5-parted ; the lobes opposite the anthers, thick, slightly cuncate, barely concave. Anthers 

 short : polliuia oval, affixed just below their apex to a short caudicle, pendulous. Stigma 

 abruptly produced from the top into a column having a 3-crested apex ; namely, two divari- 

 cate and muricate-papillose crests, with a small central emargiuate crest interposed. 



14' 2 . HIMANTOSTEMMA. (In Tribe Gonolobece ?) Corolla deeply 5-parted, soon re- 

 flexed, the broadly lanceolate lobes slightly overlapping dextrorsely, the face (especially 

 toward the base) conspicuously adorned with spatnlate and stipitnte corolline processes, dis- 

 posed without order. Crown stamineal, borne on the summit of the short column, simple, 

 with membranaceous margin bearing 10 elongated narrowly linear and stipitate liguliform 

 divisions, which are gemiuately alternate with the anthers and nearly equal the uuex- 

 pancled corolla; also 5 subulate and short processes, which are opposite the anthers. 

 Anthers short, inappendiculate in the manner of Gonolobece, applied to the sinuses of the 

 somewhat dilated and flat-topped stigma: cells opening at summit. Pollinia oval, affixed 

 by the pellucid apex to a very short caudicle, introrsely somewhat pendulous. Follicles 

 echinate. 



14 s . LACHNOSTOMA. Corolla between rotate and salverform, with tube about the 

 length of the (in bud) dextrorsely convolute lobes, retrorsely villous-barbate in the throat. 

 Crown belonging to the corolla, aduate to its tube, with free margin. 5-10-crenate or 

 lobed. Otherwise near Gonolobus.

 from seed from North America, by its flowers and follicles can be no other than this com- 

 mon Milkweed. Pods in this species are sometimes found with hardly a trace of the soft 

 spinous processes, sometimes with very long and shaggy ones.

 terminal peduncle. 



A. Meadii, TORR., p. 91, has leaves undulate in the living plant, the upper sometimes

POLEMONIACE^E. 



The genera are very difficult to define. Even Phlox has a species with prevail- 

 ingly alternate leaves and four or five ovules in each cell. The character of 

 unequally inserted stamens, by which to distinguish Collomia, breaks down com- 

 pletely (Proc. Am. Acad. xvii. 223) ; the declination of the filaments does not 

 hold through Potenwnium, and they are much more declinate and curved in sev- 

 eral species of Gilia of different sections. Some, of more than one group, have 

 an obviously but variably irregular limb to the corolla, quite as much so as in any 

 species of Loeselia. So it has become necessary to incorporate Collomia into 

 Gilia, along with certain bractless species which had been taken to form an 

 anomalous section of Lceselia. The principal characters now relied upon for the 

 genera are indicated below. 



4. (to be 2.) GrfLIA, Ruiz & Pav. Flowers naked, not involucellate. 

 Calyx partly herbaceous, scarious below the sinuses ; lobes narrow and acute. 

 Corolla from salverform or funnelform to campanulate or almost rotate. Fila-

 ovules commonly 4 in each cell. Common in California. 



Var. heterodoxa, G. heteroilo.ru, Greene, Bull. Calif. Acad. i. 10, is a branching form, 

 with more naked and spreading brauchlets, broader bracts, and the stamens, according to 

 Greene, " strongly declined." Some indications of this are to be seen in dried specimens of 

 the present and the following species. Calistoga, Parry, Greene, and elsewhere. 



G. atractyloides, STEUD., p. 142. From Santa Cruz to San Diego and southward. Corolla 

 smaller than in the foregoing, from wholly violet to purplish or wliite, with or without 

 a purple throat : stamens shorter than the lobes. According to Orcutt, a form with white 

 flowers is scentless, while one with deep-colored corollas has a strong scent like that of 

 Pennyroyal or of Pogogyne. 



6 1 . CH^ETOGILIA. Flowers short-peduncled or subsessile in the forks of the 

 leafy-congested dwarf and at length depressed stem and branches, not bracteolate :

 those of the branches and terminal clusters slightly and gradually dilated upward and rather 

 3-toothed than lobed at the truncate apex : corolla " white " or " pinkish " ; its lobes small (at 

 most 2 lines long), oblong or lanceolate, acute, not half the length of the tube: stamens 

 moderately incurved : ovules 2 to 4 in each cell. Bot. King Exp. 267. G. setosissima, var.

8. ELAPHOCERA, p. 144. 



G. Wrightii, GRAY, and G. Gunnisoni, are between Hugelia and Ipomopsis, and 

 might well be referred to the latter : their filaments are obscurely declined. The following 

 may be appen'ded to the present section, after G. polydudon. 



G. depressa, M. E. JONES. Small winter annual, divergently branched from the base, 

 depressed-spreading, minutely hirsute-pubescent, slightly viscid, leafy : leaves oblong-lanceo- 

 late or narrower (half-inch or more long), entire or with one or two teeth or short lobes, 

 acute at both ends, nearly sessile, cuspidate-mucrouate : flowers solitary in the forks, short- 

 peduncled or subsessile : calyx comparatively large (2^ to 3 lines long) ; its lobes broadly 

 subulate and attenuate-cuspidate, nearly equalling the small salverform (whitish) corolla: 

 limb of the latter sometimes deeper cleft at one sinus ; its lobes about one third the length 

 of the tube, equalling the stamens : seeds 4 or 5 in each cell, the coat mucilaginous but not 

 spirilliferous. Gray, Proc. Am. Acacl. xvi. 106. Arid districts of S. Utah, Nevada, and

G. Thurberi, GRAY, Proc. Am. Acad. xvii. 223, & p. 136. CoUomia Thurberi, Gray, p. 

 136. Seemingly a perennial : corolla commonly an inch and a half long: stamens more 

 or less unequal, either very unequally or almost equally inserted, some or all of them ex- 

 serted from the throat, but all shorter than the lobes of the corolla. Not rare in the moun- 

 tains of S. Arizona, coll. Buckminster, Le.mmon, Pringle.

 leaves mostly piimately parted (or even those subtending the flowers 3-parted) into filiform 

 rigid lobes no broader than the rhachis : flowers scattered, mostly short-peduncled : calyx 

 hirsute ; its lobes slender-subulate and almost spinulose, nearly twice the length of the cap- 

 sule : tube of the nearly salverform corolla barely twice the length of the calyx (a quarter- 

 inch long) and hardly longer than the somewhat irregular or oblique limb ; its lobes oval, 

 obtuse, mucronulate : filaments equally inserted, as long as the corolla-lobes, conspicuously 

 declined-incurved : ovules several in each cell. Lceseiia Havardi, Gray, Proc. Am. Acad. 

 xix. 87. Near Presidio del Norte on the Rio Grande, W. Texas, Huvard. Probably most 

 allied to G. Wriyhtii, of the same district.

G. deb ills, WATSON, p. 147. G. Larseni, Gray, of the preceding page, is only a smaller and 

 more condensed state of this, growing in loose volcanic ashes, there only with long and 

 filiform root-stocks, instead of a stouter stock : well-developed stems a span or more high, 

 equably leafy to the top. Extends northward to the mountains of Washington Territory 

 and N. W. Montana, coll. Cusick, Suksdorf, Watson, Canbi/, Brandegee. 



G. Nevinii. Next to G. rmilticaulis, p. 147, much more pubescent with short and above with 

 viscid hairs : leaves 2-3-piunately parted into more numerous lobes which are not broader 

 than the rhachis : flowers several and subsessile in the terminal glomerules : corolla violet, 

 with narrow tube and little dilated throat together 4 or 5 lines long and double the length 

 of the calyx, the limb comparatively small: capsule oblong, with 10 or 12 seeds in each cell.

G. latiflora, p. 147. Foliage often lightly tomentulose, when young glabrate : calyx very 

 scarious below the sinuses to the base, glabrous or minutely glandular. Varies in size of 

 flowers, &c., down to 



Var. exilis. Slender, effusely paniculate: flowers nearly all on elongated almost 

 capillary peduncles: corolla only 3 to 5 lines in length and of equal breadth of limb.- 




412 SUPPLEMENT. 



Common in S. California and east to Nevada : has mostly been referred to G. inconspicua, 

 var. sinuata, p. 148. 



G. tenuiflora, BENTII., p. 147. Radical leaves often cottony-tomentose when young, soon 

 glabrate : calyx at most 2 lines long : corolla from half-inch to inch and a quarter long 

 (including the lobes) ; the slender tube dilated into the somewhat narrowly funnelform 

 throat. S. California to S. Utah. 



G. inconspicua, DOUGL., p. 148. The panicles or flowering branches when well developed 

 are rather rigidly erect, at least not effuse ; the lateral peduncles short and erect, at least in 

 fruit. The figures of Smith and of Hooker (from weak plants raised in England, and from 

 which Beutham has mainly drawn the character) do not very well represent the species, 

 although the whole tube of the small corolla is often thus included. Yet it is very commonly 

 more exserted (as in var. sinuata), even before the fructified ovary enlarges, but always sal- 

 verform, having a small and narrow throat, and limb only 2 to 4 lines in diameter. The 

 effusely-flowered plants with ampliate throat, which were included in var. slnnatn, are now 

 taken for a small-flowered variety of G. latiflora. Apparently there are connecting forms 

 between all these species.

3. LQESfiLiIA, L. Flowers involucrate or involucellate ; both bracts and 

 calyx wholly or mainly scarious. Corolla funnelform, either regular or one or 

 two sinuses deeper. Seeds winged or margined, the surface becoming mucilagi- 

 nous when wetted. Suffruticose, rarely annual, with spinulose-toothed leaves. 



L. glandulosa, DON. Low, merely suffrutescent, ronghish-pubescent with short and partly 

 gland-tipped hairs : leaves mainly alternate, short-petioled or subsessile, lanceolate or nar- 

 rowly oblong, those next the-l-2-flowered clusters similar but small, few-toothed, not scarious 

 nor reticulated, nearly enclosing the involucre of wholly scarious oblong-lanceolate almost 

 entire bracts : corolla violet or bluish. 6 or 8 lines long : filaments more or less declined- 

 iucurved: seeds broadly winged. Syst. iv. 248; Benth. in DC. Prodr. ix. 319, in part (i. e.

 obconical throat and ovate acuminate lobes ! Bot. Gazette, vi. 217. Highest slopes of the 

 Pinos Altos Mountains, New Mexico, Greene. 



P. pectmatum, GREENE. Glabrous and glamlloss up to the minutely glandular and pu- 

 bescent inflorescence : leaflets very narrowly linear, hardly wider than the rhachis : corolla 

 probably white : otherwise not unlike narrow-leaved P. foliosissimum, of which it may be an 

 extreme variety. Bull. Calif. Acad. i. 10. Eastern part of Washington Terr., E. W.

13. ERIODICTYON, Benth. P. 175, 176, add:- 



E. sessilif olium, GREENE. Very leafy : pubescence partly villous and hirsute : leaves ob- 

 long or upper ones lanceolate, all closely sessile by a broad and truncate or subcordate base, 

 acutely and closely dentate (in age becoming glabrate and glutinous above) : otherwise 

 nearly like the E. crass! folium form of E. tomentosum. Bull. Calif. Acad. i. 201. Guada- 

 lupe Canon, and elsewhere in Lower California, not far below the U. S. boundary to All 

 Saints' Bay, Parry, Orcutt, and recently Greene. The seeds (with delicate stria- and trans- 

 verse reticulation) appear to be quite alike, as far as seen, in all the species and forms, which 

 are very difficult to define. 



E. tomentosum, BENTH., p. 176, is founded on a plant with pannose tomontum and no 

 villous or hirsute pubescence until the inflorescence is reached, such as Greene in Bull. 

 Calif. Acad. 1. c., describes from Monterey Co., but with the corollas seemingly in the same 

 imperfectly developed or deformed condition which Bentham had in his E. crassifolium, in 




420 SUPPLEMENT. 



this state "hardly surpassing the calyx (2 lines long)," and its lobes "very small, erect- 

 spreadiug." But well-developed flowers of E, crassifolium we know to be even half an inch 

 long and much surpassing the calyx. On Santa Catalina, Li/on got a narrower-leaved 

 form of the true E. tomentosum, with finer tomeutum not pauuose on the stem, and normally 

 developed salverform corollas. 



A multitude of forms from Lower and Southern California (including E. angustifolium, 

 var. pubens, Gray, Proc. Am. Acad. xvii. 224), with and without villous or hirsute inflores- 

 cence, now connect E. angustifolium with E. glutinosum. This extends northward to Oregon, 

 coll. Howell.

17. LITHOSPE1BMUM,- Tourn. P. 203, to first section add :- 



L. glabrum, GRAY. A low species of an Old World type, somewhat like L. incrassatum, 

 'branched from the annual root, smooth and very glabrous, except some minute appressed 

 pubescence : leaves spatulate-liuear : spikes of the inflorescence when evolute dense, bract- 

 less : flowers nearly sessile : calyx with spatulate-linear segments as long as the white 

 corolla, in fruit appressed to the axis, accrescent, upper portion foliaceous, the base indu- 

 rated, with midribs greatly thickened : nutlets oblong-ovate, somewhat triquetrous, opaque, 

 nearly smooth, the basilar areola rather small. Proc. Am. Acad. xvii. 227. Apache 

 Pass, S. Arizona, Lemmon. 



L. viride, GREENE. (Of the group with habit of Onosmodium to which belongs L. discolor, 

 'L. Palmeri, Watson, &c.) A foot or two high, paniculately branched, finely sericeous- 

 pubescent, not at all hispid : leaves broadly lanceolate, somewhat cauescent beneath : 

 corolla salverform (three fourths inch long), pale green, sericeous-pubescent outside, with 

 tube nearly twice the length of the linear sericeous-hirsute sepals, slightly contracted orifice, 

 and rounded oval lobes (only a line long) widely spreading: nutlets smooth and ivory- 

 white, not angled, an acute expanded margin around tbe scar. Bot. Gazette, vi. 158.

L. multifiorum, TORR., p. 204. Flowers heterogone-dimorphous, both forms now known, 

 as also of the following species, which ranks next to it. 



L. Cobrense, GREENE, 1. c, 157. Many-stemmed from a tap-root and a rosulate tuft of 

 'radical leaves', canescently strigulose (greener in age) or appressed-hirsute, and the spatu- 

 late lower leaves hispid : cauliue leaves linear, obtuse, short : corolla half-inch high and 

 with ample equally broad limb. Common from western border of Texas through New 

 Mexico and Arizona ; first coll. by Wright, and wrongly referred to L. ccmescens, f rom the 

 range of which this southwestern district is to be excluded.

I. hederacea, JACQ., p. 210. A remarkable form, seemingly of this species, perhaps a 

 hybrid with /. purpurea, is 



Var integriuscula, with ample leaves caudately acuminate, either entire or 

 with salient lateral teeth. Shell Islands, at the mouth of St. John's River, East 

 Curtiss. 



I Thlirberi GRAY, p. 212, should be removed to the foot of p. 210 : for it proves to be of 

 " the Pharbitis section, and normally with a 3-lobed stigma and 3-celled ovary (only by varia-

I. carnosa, R- BR. Prodr. 485. This proves to be the oldest name in the genus for /. aceto- 

 s '/</ la, Ru-m. & Schult., aud p. 211, and has been taken up as such. 



I. capillacea, Do.v, Syst. iv. 267. Takes the place of the preoccupied name/, muricata, 

 Cav., p. 214. /. annata, Roem. & Schult., is still earlier, but is obviously false. The genuine 

 species has an oblong tuber, erect stems and branches a foot or more in height, leaves of 

 such slender divisions as to justify the present specific name, aud peduncles hardly longer 

 than the calyx. The commonest form in Mexico, extending to Venezuela: in Arizona 

 forms occur between this and 



Var. patens. Stem and branches short and diffusely spreading : divisions of the 

 leaves from filiform to narrowly linear and obtuse. Not rare in Arizona and New Mexico. 

 In Northern Mexico, Parry & Palmer's 626 and Palmer's 910 are characteristic, and of the 

 broader-leaved kind. 



I. PlumrnerSB. Tuber globose (not half-inch in diameter) : stem declined-trailing or even 

 disposed to twine, a foot or so long : divisions of the mostly pedate leaves from narrowly 

 spatnlate-linear to nearly filiform: peduncle hardly shorter than the (inch long) corolla: 

 otherwise like the preceding, with which it has been confounded in the collections. S. 

 Arizona, }\'r. : i/l:t, Lwir, and Mr. &. Mrs. Lfinmon (no. 2839), who pointed out the characters. 

 Wherefore Mrs. Lemniou's maiden name is given to it.

 cuneate, laeiniate-dentate at the broad apex, tapering into a short petiole, coriaceous in 

 texture, nervose. Proc. Am. Acad. xix. 90. S. Arizona, in the Huachuca Mountains, 

 Lemmon. 



I. Lemmoni, GRAY, 1. c. Very like I. leptotoma, p. 214, but perennial from a thick oblong 

 tuber, smo-ith and glabrous throughout, even to the calyx: stem feebly turning: divisions 

 of the pedate leaves narrowly linear, elongated (often 2 inches long) : peduncle filiform, as 

 long as the slender petiole, one-flowered ; the pedicel above the linear-subulate bracts very 

 short : sepals oblung, acute, thin, with midrib slightly muriculate : corolla long aud narrow 

 (2 inches long), rose-color. S. Arizona, in the Huachuca Mountains, Li-amion. 



I. tenuiloba, TORR. Xeeds a separate subdivision at end of the genus: slender stems 

 freely twining : root unknown : plant glabrous and smooth : leaves peclatelv par;ed ; the 

 divisions 5 or 7, filiform, entire (inch and a half long), much longer but liardlv broader 

 than the petiole : peduncle stouter and longer than the petiole, one-flowered.: calyx-lobes 

 oblong, thiunish, mncronate-acuminate : corolla, &c., apparently nearlv as in / sayittata.

4. CONVOLVULUS, L. 



CALYSTEGIA PARAPOXA, Pnrsh, referred to on p. 215, is to be absolutely excluded from 

 our flora. The original, identified in Sherard's herbarium, is Convolvulus sagittatus of Sib- 

 thorp, C. ),ii:i>itn*, Bicb., of Greece. See Proc. Am. Acad. xvii. 228. 





C. rATKsm.iANA. Pursh, is one of the ambiguous forma between C. septum, var. repens, and 

 C. spithamceus, ns seen in the Sherardian herbarium. 




CONVOLVULAG&E. 435 



CONVOLVULUS SiiERARDi, Pursh, Fl. ii. 730, does not belong to our flora. It was founded 

 on an incomplete fruiting specimen, West Indian (not from "Carolina "), of C. micranthus, 

 Roem. & Schult. Vide Proc. Am. Acad. 1. c. 



In the first edition the character of CALTSTEGIA has " stigmas very flat " : but in living 

 plants, those of C. sepium are thick, papillose, hardly flattish, or even terete, as some authors 

 have stated. But they are soft and flatter in drying. As a genus Calysteyin entirely fails in 

 North America, as is seen in a series of species which now, with better material, are here 

 reconstructed. 



C. sepium, L., var. Americanus, p. 215. Stigmas in dried specimens from broadly 

 oval (as in the Old World) to narrowly oblong : flower always solitary. Here doubtless 

 C. Maximilian!, Xees, PI. Xeuwicd Trav. IT. Extends to the Pacific coast in Oregon and 

 California. Some of it has been referred to C. occidentalis. 



C. macrostegius, GREENE. Like C. sepium, but " suff rutescent " and large (leaves 4 

 inches long and little narrower) : peduncles 6 to 8 inches long, bearing 2 or 3 flowers within 

 the ample (inch or more long) bracts, and lateral flowers similarly bracteate : corolla short 

 and broad, cream-color (or " pale yellow," Greene:) : stigmas rather broadlv linear. Bull. 

 Calif. Acad. i. 203. C. occidentals, Watson, Proc. Am. Acad. xi. 118. The original is of 

 Guadalupe Island, off Lower California, Palmer. Also San Clemente, off San Diego, Lower 

 California, Aen" & Lijon. 



C. Califomicus, CHOISY, p. 215. This depressed and never twining species extends to 

 the coast ranges of Oregon (Uoicell, Henderson) in a glabrous form, some flowers with 

 broader stigmas, bearing a certain likeness to C. Soldanella. 



C. villosus, GRAY, p. 216. Not at all or only feebly twining: the tomentose bracts to the 

 flower, although more commonly entire and erect, are occasionally, in the most white-vel- 

 vety plants, one or both of them, hastate and short-petioled, so passing directly into 



Var. f ulcratus. Greener, the soff pubescence short and fine : leaves either broadly 

 hastate (as in the type) or narrow and more sagittate; the bracteal pair similar but small, 

 either a little below the flower, or at the base of the calyx, occasionally one or both of them 

 entire : corolla (according to L'ooper) pale yellow, probably only cream-color : stigmas 

 linear. C. luteolus, var. f ulcratus, Gray, p. 216, and the only C. lutcoJus of which there 

 is good evidence of yellow or yellowish corolla ! C. f ulcratus, Greene, Bull. Calif. 

 Acad. i. 208. 



C. occidentalis, GRAY, p. 215. Character needs emendation only in reference to the ex- 

 treme variability of the bracts: these either Calystegia-like and covering (but rarelv sur- 

 passing) the calyx, or variously smaller and shorter, or lanceolate or linear and more 

 foliaceous in texture, then at a little distance below the calyx, always in a pair, except on 

 the 2-3-flowered peduncles, when they may be disjoined. Whenever, as in the original of the 

 species, there is more than a single flower, the bracts are small and narrow. Specimens with 

 solitary flower and ample bracts referred here belong to C. sepium. Generally herbaceous or 

 with barely suffrutescent ba,se, but Mr. Greene finds stems woody to a considerable height. 

 The form with diminished bracts is C. luteolus, Gray, p. 216 (excl. var.), but everywhere 

 with white corolla, or roseate in fading. So that this last name happily disappears. 



Var. tenuissimus, GSAY, p. 215. The commoner form, throughout S. California, in 

 the drier regions usually reaching only a foot or a yard in height : leaves from lanceolate- to 

 linear- or even filiform-hastate : bracts Calystegia-like, either acuminate and surpassing the 

 calyx, or oblong and barely equalling it. This may pass into 



C. longipes, WATSOX, p. 217, which was described from mere branches. It has no bracts, 

 the uppermost reduced subulate leaves are scattered and always alternate. 



C. HavanensiS, JACQ. Suffruticose, prostrate or feebly twining, canescently puberulent 

 and glabrate : leaves thick, oblong-lanceolate or elliptical, sometimes orbicular, obtuse or re- 

 tuse and mucronate, entire (6 to 12 lines long), abruptly contracted into a short petiole: 

 peduncles one-several-flowered : pedicels longer than the calyx : corolla white, not over half- 

 inch long, deeply 5-cleft : lobes acute : stigmas oblong : capsule splitting into several valves.

The first division, containing B. ovalifolia, p. 217, which is probably large-flowered, needs 

 slight alteration, as to length of peduncle, for the following related and remarkable species. 



B. grandiflora, GRAY. Minutely sericeous-puberulent : root tuberous : stems procumbent, 

 2 or 3 feet long : leaves broadly oval or some orbicular, an inch or two long, very short- 

 petioled : peduncles rather shorter than the leaf, one-flowered, bearing two subulate bracts at 

 base of a stout pedieel : sepals broadly lanceolate, the two outer a little shorter than the 

 inner (these in fruit an inch long, surpassing the capsule) : corolla funnelform from a rather 

 long tube, blue. 3 inches in length : styles capillary, distinct nearly to base : stigmas globose.

E. leetus, GRAY. Sericeous-canesceut throughout, and with some soft villous pubescence, 

 much branched from a suffrutescent base, erect or barely spreading, 6 to 10 inches high, 

 leafy : leaves sessile, oblong-lanceolate, half-inch long : peduncles 1-3-flowered, surpassing 

 the leaves : corolla bright blue, with limb fully half-inch in diameter. Proc. Am. Acad.

BELLINIA UMBELLATA, Roem. & Schult. (Saracha umbellata, Don; Gray, Proc. Am. Acad. 

 xix. 91 ), a common Mexican species, was collected by Lemmon in S. Arizona, on the Mexican 

 frontier, perhaps only adventive. The genus is known from the present and from Physalis by 

 the enlargement and rotate expansion of the fructiferous calyx under the berry into a membrana- 

 ceous 5-angled plate. 



8. MARG-ARANTHUS, Schlecht. P. 237, add a second species, - 



M. Lemmoni, GRAY. Very much branched and decumbent, more leafy : leaves all quite 

 entire : calyx more deeply 5-dentate ; the teeth at length half the length of the tube : corolla 

 white, campanulate-urceolate above the very short tube ; orifice obtusely 5-lobed. (It might 

 be Phi/salis mimitiflora, Moc. & Sesse, but leaves not at all repand, as they are in M. solana- 

 ceus. Proc. Am. Acad. xix. 91. Cave Canon, S. W. Arizona, Lemmon.

L. quadrifidum, Dunal, founded on a rude figure, might be the same, except for larger size 



and much shorter tube of corolla, so that it is with more probability referred to L. Carolinia- 



num by Miers. 

 L. macrodon, GRAY, p. 238. Rediscovered by Pringle, beyond the border of S. W. 



Arizona, on the Altar River ; lias remarkably long and narrow calyx-lobes, white corolla 



tinged with green, and a very large hypogynous disk of a deep orange color. 

 L. Californicum, NDTT., p. 238. Distinguished by its fleshy leaves, and limb of the small 



tetramerous corolla nearly as long as the tube. Common on the coast of S. California from 



Santa Monica to San Diego. 



Var. Arizonicum. Leaves bright green, extremely fleshy, the small ones of the 



fascicles on the brauchlets pyriform or globular! Desert of Arizona, Parn/ (imperfect 



specimen was referred to L. parviflorum), at Lowell, Parish, and Maricopa, A. Gray. 

 L. parviflorum, GRAY, p. 239. S. Arizona, Thurber, Pringle. May pass into L. barbino- 



duin (which is not within our limits), but does not show the tomentulose nodes of the 



fascicles. 

 L. Premonti, GRAY, p. 239, is not uncommon in Arizona (coll. Parry, Vasey, &c.). and it 



passes into the equally abundant 



Var. gracilipes, L. gracilipes, Gray, p. 239, with pedicels from a third to half an inch 



long, often quite as long as the flower. S. Arizona, Parish, Pringle, &c. 



Other puberulent species, the first two more or less extra-limital, are : 



L. exsertum, GRAY. Very much like the last preceding: leaves spatulate (not over half- 

 inch long) : pedicels hardly half-inch long, about the length of the corolla: lobes of the 

 calyx acute, shorter than the tube : corolla-lobes very short, triangular-ovate, reflexcd : 

 stamens much exserted. Proc. Am. Acad. xx. 305. Near Altar, in N. W. Souora, 

 Pringle, 



L. Pringlei, GRAY, 1. c. Cinereous-puberulent : branches slender : leaves spatulate and oh- 

 lanceolate (about quarter inch long): pedicels 2 or 3 lines long: calyx with oblong and 

 obtuse foliaceous lobes equalling or longer than the tube and almost equalling the tube of the 

 corolla, which is barely 3 lines long, and longer than its own 5 roundish lobes : stamens 

 shorter than the corolla lobes ; filaments densely bearded at base. In stream-beds, N. W. 

 Sonora, near the boundary, Prinr/le. 



L. Parish.il, GRAY, 1. c. Resembling the preceding, equally small-leaved and puberulent: 

 pedicels 2 or 3 lines long : corolla narrowly funnelforin (5 lines long), thrice the length of 

 the obtuselv and rather short-lobed calyx, with short 5-lobed limb ; the lobes a line long, 

 ovate, obtuse, at length equalled by the stamens. Mesas in the San Bernardino Valley, 

 S. California, Parish.

The California!! species (of ) i ), which are prehensile by lateral shoots acting as tendrils, 

 now augmented, may be defined as follows : 



A. Coulterianum, BENTH., p. 252. Marked by its truly spicate inflorescence, and com- 

 paratively large corolla, with very protuberant palate greatly exceeding the short upper lip. 



.A- Orcuttianurn, GRAY. Nearest the preceding, more slender, smaller-flowered, glabrous 

 up to the loosely spicate inflorescence, which is more disposed to bear tortile branchlets : 

 corolla about 4 lines long ; lower lip not much larger than the upper : leaves linear or lower- 

 most spatulate-lanceolate : seeds tuberculate-favose. Bot. Gazette, ix. 53. Near San 

 Diego and adjacent Lower California, Orcittt. 



A. Nevinianum, GRAY, 1. c. Much resembles the foregoing : seeds longitudinally cris- 

 tate-costate, as in A. Nuttalliannm. Los Angeles Co., at San Juan Capistrano, Nevin, 

 and near San Diego, Orcutt. 



A. Nuttallianum, BENTH., p. 253. Well marked by the scattered slender-pedicelled flow- 

 ers '(with short comparatively equal-lipped corolla not over 4 lines long), all subtended 

 by ovate leaves or leaf-like bracts, and principal leaves distinctly petiolate : seeds acutely 

 cristate-costate. Extends well into Arizona, &c. 



A. subsessile, GRAY. Erect and loss diffuse than the foregoing, which it most resembles, 

 extremely glandular-viscid : flowers more racemose, longer than the pedicels or even sub- 

 sessile ; lower lip of corolla larire in proportion : leaves ovate, all sessile or nearly so : seeds 

 of the preceding. Bot. Gazette, ix. 53. San Diego, &c., Cleveland, Orcutt, and Santa 

 Catalina Island, Schumacher. 



A. subcordaturn, GRAY. Of the group with flowers sessile or subsessile in the axils of 

 sessile loaves, and very unequal calyx, to which belong A. runnns and A. Bretrcri : rather 

 large and stout, pubescent or below hirsute : lower leaves unknown ; upper closely sessile, 

 ovate, subcordate, thickish flowers half-inch long : upper sepal large and oval, longer than 

 the rest, which are linear-lanceolate : corolla half-inch long, with ample throat and almost 

 equal lips, ochroleucOus : longer filaments dilated at apex: seeds favose and the edges 

 of the pits muriculate. Proc. Am. Acad. xx. 306. Stony Creek, Colusa Co., California,

A. filipes, GRAY, p. 354. With hardly a doubt this was founded on a depauperate-flowered 

 and very attenuate form of the A. Cooperi, Gray, Proc. Am. Acad. vii. 376, which has the 

 fully developed flowers. The characters should be combined under the former and older 

 name. In canons, from N. W. Arizona to Sau Diego, where apparently it also pro- 

 duces small corollas.

A. Speciosum, GRAY, p. 354. Corolla has short or small, but not "narrow " lips, and the 

 palate closes the throat ; so that the character of the section needs correction. Inhabits 

 also San Clemente Island, Nevin & Lyon. 



A. junceum, GRAY, p. 354. This is Saccularia Veatchit, Kellogg, Proc. Calif. Acad. ii. 17,

P. CERROSENSIS (which should have been Cedrosensis), Kellogg, Proc. Calif. Acad. ii. 19, & 

 Bull. i. 145, with plate (see p. 273), from Cedros Island, off Lower California, proves to be a 

 good species, and P. brevilabris, Gray, Proc. Am. Acad. xvii. 229, is a synonym. Color of corolla 

 uncertain, but surely not " yellow." 



P. CANOSO-BARISATUM, Kellojrg, has been identified by Mrs. Currau (in Bull. Calif. Acad. i. 

 145) with P. brer i floras, Liiidl., and P. ROSTRIFJ.ORUM with P. Bridgesii: but in the description 

 the color of the flowers of the two has been exchanged. 



P. TENELLUS, Kellogg, Proc. Calif. Acad. i. 56, is by the same authority said to be P. azu- 

 reus, Benth., probably depauperate.

Revised in the light of E. L. Greene's new arrangement in Bull. Calif. Acad. i. 94-123 

 (Mi/itii/tix, Kiinanvx, Diplacus), of recent personal observations, and of the original types of 

 Bentham, Hooker, &c., in the Kew Herbarium. Polymorphous, but better retained entire under 

 five subgencra than divided into as many genera. L>ijiUicun is placed first, as having the best 

 claims to generic distinction, being shrubby. 



1. DIPLACUS, p. 275. Add char. : Capsule firm-coriaceous, narrow, sym- 

 metrical, tardily dehiscent down the upper suture, only after seed-shedding, also 

 later by the lower suture into the two placentiferous valves : yet in some plants 

 simultaneously dehiscent into the two valves. Seeds elongated-oblong. Pubes- 

 cence when developed partly of branching or somewhat aspergilliform downy 

 hairs. 



M. glutinosus, \VF.\ML. Corolla, from orange or salmon-color to pale buff. Var. linraris 

 is tin' must narrow-leaved form, in arid exposures, as Ifi/i/iims l/ilifuliux is the broader- 

 leaved junl luxuriant extreme. Var. brarhi/pus is the best-marked form, on account of the 

 villous (but deciduous) hairs of the calyx and generally pale corolla. 



M. puniceus, Sri:ri>. ( D. (/lii/inosiis, var. pnnirens, and part of var lint.aris, p. 275), com- 

 monly tall and narrow-leaved, with brick-red or blood-rod rather than scarlet corolla, and 

 only in Suutheru California, may be regarded as a species until intermediate colors are 

 met with. 




SCROPHULARIACE^:. 443 



2. CENOE, Gray. Corolla (with one exception) large for the plant, and with 

 a long-exserted and slender (even filiform) tube, expanded throat, and obscurely 

 bilabiate limb ; the lower lip sometimes small or obsolete : style pubescent above : 

 capsule cartilaginous, unequal-sided, sulcate at the dissepimental sutures, and 

 sharp-edged at the posterior dorsal one, enclosed at first in the narrow prismatic 

 and gibbous-based calyx, long persistent, indeed never detached, very tardily de- 

 hiscent, mainly by the posterior suture : placentae connate in the ovary but early 

 separating in the fruit :. purple-flowered and low winter annuals, mostly blossom- 

 ing from near the root. -- (PL Hartw. 32'J) Bot. Calif, i. 563. Eunanus (Euoe 

 and part of Eunanus proper, Greene, Bull. Calif. Acad. i. 98, 100. 



* Capsule small ami ovate or oblong-oval, much indurated : pygmy plants, flowering from the 

 ground and remaining very low, the stems in age seldom equalling or much longer than the 

 long-tubed (inch or two long) corollas, barely pubescent, neither glandular nor viscid, vernal. 



M. tricolor, LINDL. Leaves mostly lanceolate : corolla (when well developed 2 inches 

 long) with ample somewhat regular limb, pink or lilac with a dark crimson, blotch ou each 

 of the rounded lobes, the 3 lobes of the lower lip about the length of the two-lobed upper ; 

 the throat yellow and brown-crimson, commonly spotted, open funnelform, about half the 

 length of the slender tube : anther-cells bearded at base : stigma of semi-orbicular and 

 slightly unequal lobes united by their edges at base : seeds very numerous, small, oblong, or 

 obovate-obloug minutely scaberulous, becoming smooth in age. Common iu the great 

 valley of California, especially on the Sacramento. To the synonymy on p. 274, add Eunanus 

 tricolor, Greene, 1. c. 99. The former character of the fruit and seeds was taken from a 

 fruiting specimen of M. Doiiglasii, through mismatching. 



M. angustatus. Exiguous, commonly acaulescent : leaves linear and linear-spatulate : 

 corolla of the preceding species, except that the filiform tube is 4 to 8 times the length of 

 the short funnelform throat, and the lower lip rather shorter than the upper : lobes of the 

 stigma broadly cuneate : seeds (not here seen) according to Greene "few, large, favose- 

 pitted or favose-reticulate." M. tricolor, var. angustatus, Gray, 1. c. Eunanus angustatus, 

 Greene, 1. c. Mountains of the northern part of California ; first coll. by Bolander. 



M. Douglasii, GRAY. Leaves obovate or oblong : corolla with crimson-purple 2-lobed 

 upper lip forming the principal limb, the lower lip reduced to a truncate sinuately 3-crenate 

 border, or with a more conspicuous dentiform middle lobe ; the throat brown-purplish, rather 

 narrowly campanulate, about one third the length of the tube: capsule somewhat flattened 

 and with one very sharp-edged dorsal suture : seeds only 20 to 40 in each cell, comparatively 

 large, scurf v-muriculate, becoming smooth in age. Part of M. Doiiglasii, Gray, Proc. Am.

 Acad. i. 98. Chiefly in the central and northern parts of California, blooming very early. 

 Mixed first by Beutham (in PI. Hartw.) with the following species as to the flowering plant, 

 with which mature fruit of M. tricolor was distributed ; hence a confusion to which the Syn. 

 Fl. added, and also increased by taking fruit of M. Doiiglasii for that of M. tricolor. 



* * Capsule short-linear, at length arcuate : caulescent, flowering later and longer, viscidulous- 

 pubescent. 



-i With long-exserted filiform tube to the corolla, as of the section. 



M. Kelloggii, CURRAN. Erect, a span or two or becoming a foot high, with internodes 

 longer than leaves : these ovate to obovate or spatulate-lanceolate : corolla crimson-purple ; 

 its tube inch long, expanding into a short-funnelform throat and oblique limb ; short lobes 

 of lower lip only half the length of the upper and more spreading: stigma with ovate and 

 obtuse unequal lobes, or by their union obliquely peltate : capsule narrow, obtuse (4 or 5 

 lines long and a line thick), rather terete, moderately unequal-sided : seeds comparatively 

 few and large, obovate. Curran in herb. Gray. M. Doufflasii, partly, Gray, Bot. Calif., &c.,

-i -! Ambiguous species, with corolla of Eunanus, and little exserted, but with oblique late- 

 dehiscent capsule of CEnoe. 



M. latifolius, GRAY, p. 274. Extra-limital. The capsule in plant raised from Palmer's 

 seeds appears to be only moderately oblique, linear-oblong, obtuse, and not indurated ; but 

 as now received from Mr. Greene, from its native habitat, and fully mature, it is lanceolate, 

 strongly oblique, and as if bent on its broad base ; the upper carpel much larger than the 

 other, very gibbous and sharp edged dorsally, and there very tardily dehiscent. 



3. EUXAXUS, Gray, Bot. Calif. Corolla from tubular-funnelform to nearly 

 campanulate, with either obscurely or manifestly bilabiate limb, the proper tube 

 either moderately exserted or included in the campanulate or oblong calyx : style 

 glandular-pubescent above : stigma usually peltate-fun nelform, obscurely 2-lobed 

 or entire : capsule symmetrical, from firm-chartaceous to menibranaceous, dehis- 

 cent by both sutures into two valves, which bear the separated placentae : low or 

 occasionally taller annuals, most of them glandular- or viscid-pubescent and 

 heavy-scented. 



* Corolla only a quarter-inch long, slender, only slightly exserted out of the broad and ventricose 

 calyx until elevated on the growing capsule: valves thin-chartaceous. 



M. Rattani, GRAY. Viscid-pubescent, a span or two high : leaves oblong ; upper about 

 equalling the sessile flowers : calyx very viscid, when fructiferous little higher than broad, 

 a little oblique at orifice, and with short ovate teeth : corolla rose-purple, its lobes barely a 

 line long, equal except that the upper are united to near the middle : capsule narrowly 

 ovate-lanceolate, nearly half exserted: seeds oblong-oval. Proc. Am. Acad. xx. 307.

 the campanulate or oblong calyx: capsule-valves metnbranaceous or chartaceous: plants a span 

 or two high and brandling when luxuriant, when depauperate dwarf and simple, beginning to 

 blossom from near the root. 



H Calyx not manifestly oblique at orifice, but lower teeth usually a little shorter. (Species of 

 difficult discrimination.)

 bvate-oblong to nearly linear : calyx-teeth short, broadly lanceolate, acutish : corolla half to 

 two-thirds inch long and with somewhat bilabiate limb 4 or 5 lines broad, bright yellow, 

 often purple-dotted in the throat, sometimes whole throat or even the limb turning reddish :

 plants almost glabrous: leaves obovate and spatulate-oblong, all witli tapering base: calyx- 

 teeth broadly lanceolate or triangular, acutish or when outspread obtuse, but acute when 

 the tips are conduplicate, a quarter or a third the length of the oblong tube : corolla rose- 

 purple with darker or yellow throat, mostly two-thirds or three-fourths inch long ; the limb 

 half-inch or less wide, evidently bilabiate and the lower lip a little shorter than the upper: 

 seeds oval-oblong. (Supra, p. 274, excl. the yellow-flowered form and the var.) California 

 to interior of Washington Terr, and Wyoming, first coll. by Toimie. 



M. Bigelovii, GRAY, p. 274. Viscid pubescent, sometimes viscidly villous : leaves nearly of 

 the preceding or more acute, the upper ovate and acuminate: calyx-teeth triangular and 

 acuminate or subulate-acute, about half the length of the tube : corolla crimson, sometimes

M. ringens, L., extends northward to the Hudson's Bay district. This and the allied 

 J\L uliitiis are perennial by stoloniform rootstocks, produced rather late in the season. The 

 corolla is not really ringeut, although the lips are widely open, for the throat is personately 

 closed. 



The remaining Western species, i. e. all after M. alatus, p. 276, are re-elaborated as fol- 

 lows : 



* * * Large-flowered to small-flowered Western species: corolla yellow and with or without 

 dark blotches or dots, or in a few rose-colored or dark crimson : seeds mostly smooth or with slight 

 reticulation or striation. 



+ Filiform-scapigerous and stoloniferous perennial, the stolons often producing scaly bulblets 

 after the season's growth: scattered and long hairs viscous: leaves 3-nerved.

 slimy-viscous, commonly much so, musk-scented: leaves pinnately veined: calyx-teeth narrow 

 and acute: capsule acute and not stipitate: seeds globular. 



M. moschatus, DOUGL., p. 278. Weak stems sometimes 2 or 3 feet long. Runs into two 

 extreme forms : 




SCROPHULARIACE.E. 447 



Var. longiflorus, GRAY. A form growing in drier soil, less viscid-villoiis, and with 

 elongated corolla. M, moniliformis, in part (the villous- and more or less viscous- 

 pubescent plant), Greene, Bull. Calif. Acad. i. 119. Common especially in the Sierra 

 Nevada. 



Var. sessilifolius. Leaves all sessile on upright or ascending stems (these some- 

 times a foot or two high, very slimy), hut those on decumbent shoots from the rootstocks 

 of the same plant not rarely well-petioled. M. inodorus, Greene, 1. c., but the plant as 

 strongly musk-scented as the ordinary species, at least in some cases. Not rare in wet 

 places, from San Bernardino Co., California, northward, and passing into the ordinary form 

 in Oregon. Calyx-teeth in all the forms variable in length and width. 



H 1 ( Leafy-stemmed and slender, perennial by filiform rootstocks, scentless, the minute 



pubescence (if any) not viscous: leaves essentially pinnately veined, the peduncles seldom sur- 

 passing them : calj*x-teeth acute, rather narrow and little unequal : corolla open, about inch 

 long: capsule acute, not stipitate-contractecl at base. 



M. moniliformis, GREENE, in part. Filiform rootstocks ending in small moniliform 

 tubers : stems a span or two high, simple and erect or with spreading brandies : leaves ovate 

 or oblong, acute or obtuse, half-inch to inch long, sparingly denticulate : calyx-teeth trian- 

 gular, a quarter of the length of the tube : corolla barely inch long or less, light yellow, 

 narrowly fuunelform, short-bearded in the throat, the obscurely bilabiate limb half-inch in 

 diameter. Bull. Calif. Acad. i. 119, excl. the villous plant, on which, as to herbage, the 

 species was founded. M. dentatus, var. gracilis, Gray, Bot. Gazette, vii. 112. M. luteus,

 Greene. 



M. dentatus, NCJTT. Copious rootstocks filiform : simple stems a foot or less high : leaves 

 ovate to oblong, acute, one to three inches long, serrate with numerous commonly coarse 

 and salient teeth : calyx-teeth triangular-subulate, half the length of the tube : corolla ven- 

 tricose-fuunelform, fully inch long, deep golden yellow, with widely open throat and com- 

 paratively short moderately bilabiate limb, the two conspicuous lines of yellow beard ex- 

 tending from the lower sinuses to near the base. Herb. Hook., &c. ; Benth. in DC. Prodr. 

 x. 372 ; Gray in Bot. Gazette, vii. 112 ; Greene, 1. c. 109. In woods, Columbia River west 

 of the Cascades, Nuttull, Hou-rll, and western borders of California, Rattan. Nearly related 

 are M. Orizahe, Benth., of Mexico, M. sessilifolius, Maxim., of Japan, which has closely 

 sessile leaves and shorter and broader calyx-teeth ; also M. Nepalensis, in the erect and 

 larger-flowered form, which has broad and short abruptly pointed calyx-teeth. 



) -i H \ Leafy-stemmed, perennial by stoloniferous or creeping basal branches, or sometimes 



by filiform rootstocks, but seedlings flowering the first year, and precocious depauperate ones 

 dying at maturity of fruit, glabrous or sometimes minutely pubescent (but never clammy-hairy 

 or mucilaginous): leaves several-nerved from the base or near it: peduncles in fruit spreadinc: or 

 else the apex nodding: calyx at least in fruit oblique-sided and more or less inflated, also oblique 

 at orifice; the teeth all obtuse and broad (sometimes mucronulate, but never acute except when 

 folded); uppermost larger ; lower turned upward toward the upper at maturity of fruit : corolla 

 more or less personate : capsule obtuse or retuse, mostly contracted or short-stipitate at base. 

 H- Small-flowered for the size of the leaves and (leafy) branches; the light yellow corolla (at most 



half-inch long) not twice the length of the calyx: capsule short-oval, very obtuse or retuse. 

 M. glabratus, HBK. Diffuse or ascending from a creeping base : stems somewhat quad- 

 rangular : leaves round-oval or ovate, mostly denticulate or dentate; lower with margined 

 petioles, upper sessile by broad base : flowers mostly subtended by undiminished or little 

 diminished leaves : upper calyx-tooth much larger than the lower. Nov. Gen. & Spec. ii.

Var. Jamesii. Diffusely procumbent, rooting extensively : leaves mainly orbicular 

 and almost entire, some approaching reniform, upper ones hardly diminished and equalling 

 the subtended peduncles. M. Gej/eri, Torr. in Nicollet Rep., 1843 (157), 237. M. Jamcsii, 

 Torr. & Gray, & p. 276. The most northeastern in its range, and extends well into Mexico, 

 if not to Guatemala. M. Madrensis, Seem. Bot. Herald, 322, t. 58, seems to be a diminu- 

 tive form of it. 




448 SUPPLEMENT. 



Var. adscendens. A large and robust form (as sometimes in Mexico), rising a foot 

 or two high from the creeping base : branches freely racemosely flowered at summit ; the 

 upper and sometimes connate rounded leaves being much reduced and bracteiform. 

 M. glabratus (chiefly), Gray, Bot. Mex. Bound. 116. M. Hallii, Greene, Bull. Calif. Acad. 

 113, but species not truly annual, nor calyx-teeth acute. The specimen of Hall described 

 from was a cultivated one. Colorado and west to the Grand Canon in N. W. Arizona, 

 south to Mexico. Conies nearest to the following. 

 H- -H- Large-flowered for the size of the plant; the golden yellow and sometimes crimson-clotted 



corolla ample compared with the calyx, the larger even an inch and a half long: capsule oval or 



slightly obovate, short-stipitate. 



M. luteus, L., p. 277. Exclude the syn. M. ScouJeri, and from the var. alpinus exclude the 

 syn. M. dentatus, Nutt. (which see above); and also M. cupreus, Regel (M. luteus, var. 

 cuprea, Hook. Bot. Mag.), which belongs to a distinct Chilian species. The original Chilian 

 M. lutetis, as Bentham decided, although usually distinguishable, cannot be specifically sepa- 

 rated from the Northern coast form, M. giittatus, DC. Cat., and of Greene, 1. c., &c., to which 

 pertain M. luteus, Bot. Mag. t. 1501, Bot. Hep. t. 661, and Jacq. f. Eel t. 92. The slender 

 shoots from the base of the stem either root and form stolons, or not rarely rise and bear 

 small leaves and flowers. 



Var. alpinus, GRAY, p. 277 (excl. syn. as above). Includes a series of mountain 

 forms, varying from two inches to near a foot high, clearly perennial, proportionally large- 

 flowered. Small forms with round and nearly entire leaves answer exactly to M. Tilingii, 

 Regel, Garteufl. xviii. 321, t. 631, plants of which, from the same sowing, developed next 

 year into the typical N. American species, shown in xix. 290, t. 665 ; also in the gardens 

 under this name and as " M. Raczli," the latter answering to M. Tilingii, Greene, 1. c., from 

 near Summit Station. 



Var. depauperatus, GRAY, 1. c. partly. M. microphyllus, Benth.! in DC. Growing 

 with the larger or ordinary plants, evidently an extreme depauperate form, either seedling 

 or showing the creeping stolons ; with filiform stem 2 to 7 inches high, l-4-flowered; leaves 

 a quarter-inch or so long, and corolla 6 or 7 lines long. Grows with the larger forms on 

 Columbia River : specimens exactly like those of Douglas from same district (except that 

 some show the stolouiferous base) were received from Mrs. Barrett. 



M. Scouleri, HOOK. Erect, from a stoloniferous base, a foot or two high : leaves thick, 

 very smooth and shining, oblong-lanceolate (an inch or two long, 4 to 6 lines wide), obtuse, 

 evenly callous-denticulate ; lower tapering into petioles of equal length ; floral ones short 

 and small, ovate and amplexicaul : flowers apparently of the preceding, but corolla shorter. 

 El. ii. 100; Benth. in DC. 1. c. On the Columbia River, Scouler, in fruit only. Now 

 rediscovered, in flower, in the mud on the south shore of the river (sometimes covered at 

 high tide) about four miles above Astoria, by T. Median, probably near Scouler's original 

 station. 



H H H 4 -1 Pure annuals, leafy-stemmed, various in habit and size: no mucilaginous- 

 clammy hairs: seeds oval or oblong, mostly with a smooth close coat. 



H- Comparatively large-flowered, the yellow corolla inch long and broad: upper cauline leaves 



connate into orbicular disks, glaucous: calyx less oblique than in succeeding. 



M. glaucescens, GREENE. Erect, often tall, glabrous and glaucous, except the radical 

 and lower cauline leaves, which are sometimes villous-pubescent ; these cordate- orbicular, 

 crenate-dentate or incised, sometimes almost lyrate, slender-petioled ; the perfoliate disks 

 denticulate or entire : inflorescence at length racemiform : corolla with ample throat : style 

 minutely pubescent : calyx campanulate, slightly arachnoid-villous at the throat within, 

 appearing repand-truncate, the teeth being very short and broad, in fruit nodding on the 

 ascending peduncles, the two lower teeth incurving in the manner of the following. Bull. 

 Calif. Acad. i. 113. California, along streams in the foot-hills of the Sierra Nevada, from 

 Lassen to Butte Co., Fremont, Mrs. Austin, A. Gray. 



*-* -H- Middle-sized to small-flowered (even in same species): herbage not glaucous: corolla yel- 

 low: calyx especially when fructiferous and ventricose oblique-sided and oblique at orifice, 

 strongly plaited-angled, mostly with acute or acutish teeth, the lower at maturity turned toward 

 the larger uppermost: fructiferous peduncles mostly spreading or the apex nodding: capsule 

 distinctly short-stipitate.

Mo nasutus, GREENE. Quite glabrous, or herbage minutely pubescent ; larger forms a 

 foot or two high, erect, with 4-angled stout stem, corolla and fruiting calyx each half to two- 

 thirds inch long, and rounded leaves one or two inches in diameter ; exiguous forms abound- 

 ing with the same (mostly flowering earlier or when drier), diffuse, delicate, thin-leaved, 

 reduced to a span or so or even an inch or two high, with rounded leaves from half-inch to 

 a line or two broad, fruiting calyx from 5 to 3 lines long, and very small hardly exserted 

 corolla : leaves chiefly orbicular or round-ovate and lower subcordate : calyx broadly ven- 

 tricose-ovate in fruit, conspicuously pointed by the triangular-lanceolate projecting upper 

 tooth : corolla commonly with a crimson-purple spot on the lower lip. M. nasutus &, M.

 branched from the very base, a span or two high, with stems and sometimes foliage purple- 

 tinged : leaves ovate to lanceolate, from denticulate to strongly and acutely dentate, taper- 

 ing into a margined petiole (both together seldom inch long), upper much surpassed by the 

 filiform at length divergent peduncles : corolla half to three-fourths inch long, with ample 

 limb (bright yellow) : fructiferous calyx oblong-ovoid in fruit, then half-inch long or more 

 and gibbous, with closed mouth; the short triangular teeth nearly equal and alike, but four

H- -H- -H- Small-flowered, very minutely glandtilar-puberulent or glabrous, but viscidulous, and 

 when much so musk-scented: calyx campanulate-oblong, hardly at all unequal-sided at maturity 

 or ventricose,' but nearly filled by the oblong capsule; the short-toothed orifice as if truncate and 

 moderately oblique; the upper and two lateral at length triangular-subulate teeth a little shorter 

 than the two larger and rounded-obtuse more united lower ones! 



M. alsinoides, DOUGL., p. 277. British Columbia to N. California, first coll. by Menzies. 

 Runs clown to the exceedingly tiny specimens of Scouler, &c. (vnr. minimus}, while the 

 larger are even a foot long, and some of the (5-nerved at base) leaves are two inches long, 

 including the petiole. Nuttall distributed this species under the name of M. tenel/ns. Now 

 that its peculiar characters are indicated it cannot be mistaken. Yet it had been confounded 

 with some other species, and with M. Puhifercr, Greene, 1. c. Suksdorf remarks that the 

 peduncles carry the capsules as closely as possible to the rocks. 



++ ++ .M. -H. Small-flowered, or sometimes rather large-flowered for a small plant: calyx not gib-

ACANTHAC1LE. 457 



8. ANISACANTHUS, Nees. Species rearranged, as follows: - 



# Calyx-lobes attenuate, longer than the stipe and mostly about equalling the body of the capsule 

 (a third to half an inch long): corolla dull red, funnelform above, with lobes much shorter than 

 the tubular portion: flowers distinctly pedicellate, chiefly in axillary and mostly leafy fascicles.

 Arizona, Primjle, Parish, &c. Here belong the U. S. portion of Drejera puberula, Torr., 

 and A. pumilus, p. 328, not Nees. 



* * Calyx shorter, not surpassing and only in A. mrgularis ever equalling the stipe of the 

 capsule": flowers usually, at least the upper ones, spicately or racemosely disposed along the 

 branchlets and secund, the upper subtending leaves reduced to subulate bracts. 



A. insignis. Puberulent or nearly glabrous : leaves mostly linear-lanceolate to linear : 

 flowers pedicellate, in lateral clusters from axils of fallen leaves and short-racemose on 

 evolute small-braeted brauclilets : calyx puberulent-glandular ; the almost distinct sepals 

 linear-subulate, 2 or 3 lines long: corolla rose-red or even salmon-color, 2 inches long; the 

 linear lobes shorter than the upwardly enlarged tubular portion : stipe when well developed 

 longer than the body of the capsule. A. pumilus, Watson, Proc. Am. Acad. xviii. 133.

 capsule, and in the State of Chihuahua, Pringle, with stipe half-inch loug ) 

 A. "Wrightii, GRAY, p. 328. Calyx glabrous or nearly so, remarkably short, barely 2 lines 

 long, and the lobes rather obtuse, seldom half the length of the stipe : corolla with throat 

 very little dilated. 



A. ptfMiT,us, Nees, Hemsl. Biol. Centr.-Am. Bot. ii. 522, includes A. Greggii, p. 328, and 

 has tomentulose-pubescent and short calyx, the scarlet-red corolla of the next, but with its 

 ligulate-linear lobes longer than the narrow tube. 



A. VIRGULARIS, Nees, has a nearly glabrous calyx with slender subulate lobes, a scarlet-red 

 corolla with lobes shorter than the slender tube, and stipe shorter or not longer than the -body 

 of the capsule. To this belongs the plant of Berlaudier referred to Drejera puberula, Torr. 

 Also the A. pumilus, (Erst. PI. Liebm. Palmer's Mexican no. 1016 has the leaves and corolla 

 of the most narrow-leaved A. virgularis, but the calyx of A. Wriahtii. A.junceus, Hemsl., the

 gularis, like one recently collected in Chihuahua by.Pringle. 



12. DI ANTHER A, Gronov. At end of the genus, p. 330, add: 



JACOBINIA NEGLECTA, Sericographis neglecta, Oersted, a native of the Mexican coast-region, 

 has been received, through P. J. Berckmans, in living specimens from Florida, where it is said 

 to be spontaneous, probably through some mistake. It is somewhat shrubby, with oblong- 

 lanceolate or broader and acuminate leaves, flowers (inch and a half loug) secund, in naked 

 triple spikes on a slender axillary peduncle : calyx and bracts short : corolla light brick-red 

 and narrowly tubular : connective of the anthers broad enough to refer the plant to Dianthera, 

 the slightly higher and larger cell (or rather the connective) apiculate. 



15. DICLlPTEBA, Juss. 



D. resupinata, Juss., p. 331, covers two species. The true one is annual, with a loosely 

 'branched stem : leaves from ovate to oblong-lanceolate, rather long-petioled : involucral 

 bracts cordate-rotund: seeds muricate with subulate minutely setuliferous processes. -

 leaves ovate, acuminate (over an inch long), long-petioled ; upper much smaller, ovate- 

 elliptical, short-petioled, equalling the axillary subsessile leaf-like involucral bracts : these 

 at first spreading, deltoid-roundish, very obtuse or retuse, rarely mucronulate, abruptly con- 

 tracted at base, there commonly coalescent into a narrow cup : corolla not surpassing the 

 involucre: seeds muricate with minutely setuliferous processes. Proc. Am. Acad. xx. 308.

 from a perennial or perhaps annual root : leaves mostly obovate in outline, once or twice 

 3-5-parted into short and narrow lobes : lower flowers sparse and in the axil of leaves (as in 

 the nearly related species), and most of the upper exceeded by the linear or subulate bracts : 

 fruit shorter ; nutlets granulose-scabrous at the commissure. PI. Hartw. 21 ; Watson, Proc.

 leaves from linear-spatulate to obovate, quarter to half inch long, veinless, subsessile; pri- 

 mary ones articulated (in the manner of the genus) with the pulvinns or very short persistent 

 petiole, which after their fall often becomes spinesceut (but barely a line long) : calyx

Var. nana (M. nana, Gray, 1. c.), with tube of the more slender and pale rose-colored 

 corolla little exserted from the calyx ; and 



Var. tenuiflora, with corolla full inch long and much exserted, pale rose-color, the

Var. microcephala. Much branched : heads much smaller : involucral bracts 

 small, not over quarter-inch long. Potrero, near San Diego, Orcutt,

 somewhat glabrate, pauiculate, very leafy: leaves linear-oblong, 3-5 lines long, obtuse, 

 veiuless and glabrate above, conspicuously punctate : calyx-teeth short, erect, ovate or tri- 

 angular : corolla white, with purple dots on the lower lip, villous outside, hardly thrice the

 Reverchon. 



26. ACANTHOMfNTHA, Gray. A second species, with similar aspect 

 and bracteal leaves, differs remarkably in the flowers, most so in the upper lip of 

 the corolla. The shorter and smaller lower lip of the calyx in both species is 

 erect and appressed to the upper in fruit. 



A. ilicifolia, GRAY, p. 365. Add : Cusps of the oblong calyx short, not longer than the 

 teeth : upper lip of corolla straight and erect, entire ; lower much larger, saccate at base, 

 its lobes roundish, lateral ones recurved, middle one broad and deeply 2-lobed : anther-cells 

 of fertile stamens confluent at dehiscence; posterior stamens abortive, reduced to small fila- 

 ments with rudimentary anthers. Add : Hook. f. Lot. Mag. t. 6750. This singular plant 

 abounds near San Diego and southward, and has been distributed by Pringle, Orcutt, &c. 



A. lanceolata, CURRAN. Stouter, pubescent : cauline leaves lanceolate or oblong, spar- 

 ingly spinulose-dentate ; teeth of the bracteal ones long-aristate : calyx more elongated ; 

 the teeth long-aristate ; middle one of the upper lip erect and the lateral turned forward in 

 fruit; lower lip 2- parted, its lanceolate segments tipped with shorter awns: corolla with 

 narrow and longer upper lip somewhat falcate-incurved (in the bud strongly incurved over 

 the lower), 2-cleft at apex ; lower nearly one half shorter, less saccate at base ; its lobes ob- 

 long and entire, the middle one longer and narrower : all four anthers polliniferous and 

 their cells distinct, but those of the posterior stamens smaller : style sparsely pilose. Bull. 

 Calif. Acad. i. 13. California, a single specimen found in Alameda Co., by E. Brooks, 1878.

 oblong- or deltoid-ovate, creuulate (about inch long), with either truncate or subcuneate 

 base, rather slender-petioled : bracts small and canescent : calyx narrowly oblong, atom- 

 iferous : corolla an inch long, rose-red ; lower part of the throat moderately gibbous-ven- 

 tricose ; lips only a third the length of the throat and tube : style bearded above. Froc.

 lected by Havard, " near a garden" in Presidio Co., Texas, on the Mexican border. 



29. AUDIBERTIA, Benth. 



A. incana, BENTH., p. 372. At the southern part of its range this species exhibits two 

 remarkable varieties : 



Var. pilosa, with upper part of stem and whole inflorescence villous-pubescent. 

 Northern base of San Bernardino Mountains, on the border of the Mohave Desert, Parish. 



Var. pachystachya. Large, 2 or 3 feet high, minutely puberulent, hardly cine- 

 reous : spiciform thyrsus over an inch in diameter : bracts over half-inch long. Bear Valley 

 in the San Bernardino Mountains, Parish. Southern border of San Diego Co., Palmer. 



A. Vaseyi, T. C. PORTER. In the division with A. Palmeri, the inflorescence and corolla 

 of that species, but the herbage whiter, and only lower leaves rugose-venulose : bracts and 

 calyx-teeth aristate. Bot. Gazette, vi. 207. S. California, at Mountain Springs, San 

 Diego Co., G. R. Vasei/, 1880. Also San Bernardino Co., W. G. Wright, 1880, a form with 

 bracts and all the calyx-teeth tipped with very slender and even capillary awns. In Vasey's, 

 less attenuate and less prolonged, those of the bracts and upper calyx-tooth more rigid, or 

 as a cusp rather than an awn. Flower (with the exserted stamens) about an inch long.
