The design of this work is to illustrate the Botany of the United States by figures, with full analyses, of one or more species of each genus, accompanied by descriptive generic characters and critical observations. The figures in all cases are drawn directly from nature, by Mr. Sprague, and from the living plant whenever that is practicable. In almost every instance, the whole plant, or a branch or smaller portion, in flower and often also in fruit, is delineated of the natural size ; and the microscopical analyses, as numerous as the compass of an octavo page will allow, are so chosen as to display the principal floral characters of the genus, from the aestivation of the flower-bud to the fruit, the seed, and the embryo. When need- ful, on account of size or of subgeneric diversity, two plates are de- voted to the illustration of a single genus. On the other hand, char- acters which are uniform or nearly so throughout a whole order are not repeated upon every plate.
The illustrations are not drawn from various orders and classes at random or convenience ; but the natural families are taken up in regular sequence, according to the arrangement now most prevalent among botanists (following very nearly, though not implicitly, thp order adopted in the Flora of North America by Dr. Torrey and myself), and all our genera of each family are published together, in their proper places ; thus rendering the volumes systematically complete, as they appear. This plan, which has never been carried out, so far as I am aware, in any extensive publication of the kind, while it should increase the immediate usefulness and value of the work, at the same time renders still more onerous what is at best a

formidable undertaking. The plan and nature of this publication are obviously such as to preclude all expectation of emolument. It is our determination, however, to carry on the work to its com- pletion (in about ten volumes like the present), if the patronage re- ceived shall warrant the hope of a moderate remuneration to the artist. The ample and rapidly accumulating materials at my dis- posal, both of specimens in the Herbarium, and of living North American plants in the Botanic Garden under my charge, and the prompt assistance offered by a large number of zealous correspond- ents, while they afford unusual advantages for the purpose, render me increasingly desirous to turn them to useful account by prosecut- ing an undertaking which may serve to facilitate the more thorough study of Botany in this country, and perhaps contribute in some de- gree to the general advancement of the science.
The higher character of the later as compared with the earlier executed analyses, as well as the further improvement which will be manifest to the experienced botanist in the second volume, — now in an advanced state of preparation, — is attributable to the increasing botanical knowledge of the self-taught artist who is associated with me in the work. And, although I am alone responsible for the text, I must in justice add, that whatever of original value these illustra- tions may be found to possess is largely owing to the scientific in- sight and the careful investigations of Mr. Sprague, as well as to his skill and accuracy in delineation. •
The plates are engraved upon stone, in a style (capable of further improvement) well adapted to this class of subjects, by*Mr. Joseph Prestelc, a worthy artist, formerly of Munich, but now and for sev- eral years past resident at Ebenczer, near Buffalo, New York.
As to geographical extent, this work is intended to comprise all the genera which have indigenous representatives within the States of the Federal Union as now constituted. It therefore includes Texas, but not the country west of the organized States of Arkansas and Missouri.

The Crowfoot Family presents so many gradations and diversities of form and character, that it cannot readily be defined, although there is no question as to its boundaries, nor any other hypogynous and polyandrous family with which any of the genera are likely to be confounded. The prin- cipal diversities it presents are brought sufficiently into view in the subjoined conspectus of our genera, arranged under their proper tribes. It should be mentioned, as exceptional to the ordinal character, that Zanthorhiza has few and definite stamens, which is also the case, although less constantly, in sev- eral other genera : and in Nigella the ovaries are more or less united.
An acrid principle, which is mostly dissipated in drying or by heat, per- vades the whole order; so that the fresh herbage, roots, &c, are poison- ous. Many have showy flowers, and are cultivated for ornament.
While engaged in preparing the drawings for these illustrations, during the spring and summer of 1846, Mr. Sprague directed my attention to the fact, that in all our Ranunculaceas with a solitary suspended ovule, the raphe is dorsal, or external, that is, on the side next the dorsal suture of the car- pel, and not on the side of the ovulum which is next the placenta, where it properly belongs, according to the general rule long since laid down by Mr. Brown.* I find that this anomaly has been noticed by Schleiden.f and re- cently by Barneoud, % who, however, has not very clearly indicated the pe- culiarity. It would appear that it arises from the very early reversion of an ovule like that of Ranunculus, developed from the upper part of the ventral suture, at a point which in subsequent growth becomes the summit of the cell; and thus, like the case of later reversion in Euonymus, long since

pointed out by Mr. Brown (and which may also be observed in several other instances), serves to confirm the general rule. The analogous eversion of the raphe, in many Rhamneae, is shown by Mr. Bennett to arise from the lateral torsion of the funiculus : but " the object of this displace- ment," lie concludes, " it is difficult to conjecture."' * Perhaps some light may be thrown upon it by the present eases, in which the design of this arrangement may, I think, be distinctly perceived ; namely, to facilitate the fertilization of the ovule, by placing its foramen in juxtaposition with the placenta, or that portion of the carpel (the confluent edges of the infolded metamorphosed leaf) which is in the ovary a direct continuation of the stig- matic surface or lines of the style, f and through which impregnation is ef- fected. A glance at the analyses on Plates 2 to 5, especially those of He- patica (Plate 5, fig. 4) and Myosurus (Plate 8, fig. 6, &c.), will render this evident, and show that, if the ovule were brought into the normal position, its orifice would be thrown to the side of the cell farthest from that through which the fecundating influence is communicated.
In the case of Rhamnus, where a solitary anatropous ovule arises from the very base of each cell, a broad ventral funiculus, interposed between the foramen and the placental surface, may readily be conceived to offer an ob- struction to fertilization, while the subsequent lateral torsion of this funicu- lus would bring these parts into the most favorable position. Where there is a pair of ovules, as in Celastrus, no displacement is needful for the attain- ment of this end ; since the raphe is originally lateral in such cases, that is, the two raphes are applied face to face, or very nearly. This equally occurs in horizontal collateral ovules, as in Magnolia, Plate 22, and no less so where they consist of many pairs, as in Helleborineae generally, or even where the numerous ovules are not collateral. Indeed, this may be assum- ed as the typical condition ; the ovules, which are a growth from the pla- cental margins of the infolded leaf, being themselves likewise folded inwards, thus bringing their raphes next the suture.
In no instance do we find the pericarp of the monospermous species co- herent with the integument of the seed, as described by De Candolle and by Endlicher.

* The C. crispa of De Candolle, Syst. 1. p. 162 (spec. hort. Audib.), is a form, or near ally, of C. Viticella or C. campaniflora, and undoubtedly not an Ameri- can plant. This accounts for his placing the species in the section Viticella, and for liis remark under C. campaniflora. The fruit, in the rude figure of Dilleni- us, upon which Linnteus founded the species, is delineated as if the persistent styles were perfectly naked and glabrous, while the description merely states that they are not plumose. They are usually about as hairy as here represent- ed.— Dr. Lindley (in Bot. Reg. for 1846,^01. 32. t. 60) has lately attempted to elucidate this species and its allies, but not, in all respects, with the best suc- cess. There is here merely room to state that C. cylindrica, Bot. Mag. t. 1160. is surely the same as the C Viorna, Andr. Bot. Rep. (which Lindley says is C Hendersonii) ; and that the C. crispa, Bot. Mug. t. 1892, is not C. reticulata, but clearly the same as his own C. crispa (which will be found not to have a "short- tailed mucronate fruit") and the one here figured; of which the C. cordata Bot. Mag. t. 1816, is merely a variety.

Pasque-Flower.
Calyx of 6 petaloid membranaceous sepals, imbricated in aestivation in two series, silky-bairy externally, at length deciduous. Petals, or rather sterile stamens, gland-like, sessile or unguiculate, very small, shorter than the fertile stamens, or none. Stamens indefinite, in several series, hypogynous : filaments filiform, glabrous: anthers short, fixed by the base, neither extrorse nor introrse ; the cells opening lengthwise laterally. Pistils numerous, capitate on the globular or hemispherical receptacle : ovary one- celled, one-ovuled, prolonged from the apex into a hairy style many times exceeding the ovary ; the stigma unilat- eral at its naked summit. Ovule suspended, anatropous ; the raphe dorsal.
Fruit a head of many sessile achenia, which are caudate Avith the elongated and persistent plumose-bearded styles : receptacle (gynophore) hemispherical. Seed suspended from the summit of the cell, oblong. Albumen between corneous and fleshy. Embryo minute, next the hilum, cor- date, the short cotyledons spreading : radicle superior.
Herbs, with fusiform or thickened and ligneous perennial roots bearing abbreviated caudexes at their summit ; whence is emitted, from a kind of scaly bud, a vernal, simple, one- flowered, involucrate scape, and soon afterwards, or at the

same time, a tuft of radical ternately-dissected leaves. Peti- oles dilated at the base ; their withered remains persistent. Involucre distant from the flower, soon remote, from the elongation of the fructiferous peduncle ; in Eupulsatilla simply multifid from the confluence of its three verticillate leaves into a cup or ring at the base, the linear segments uniform ; or, in Pkeonanthus (P. alpina) of three distinct, short-petioled leaves, resembling the radical ones. Flowers large (2 to 3 inches broad) : sepals purplish, violet, white or rarely sulphur-color. Stems and young leaves, &c, villous.
Etymology obscure. The popular name of Pasque-flower was given in Europe, because the blossom appears at Easter.
Properties. Acrid and poisonous, at least when fresh. Some species have been esteemed in obstinate cutaneous diseases, chronic ophthalmia, &c.
Geographical Distribution. Northern and colder regions of the Old World, especially on mountains or elevated plains ; two species (one of each subgenus) extending into North America, of which one reaches the western part of the United States proper. — Pritzel, misled by the name which Nut- tall gave to our species (Anemone Ludoviciana), and not aware that the whole, country which borders on the Missouri River was formerly called Up- per Louisiana, has wrongly extended the geographical range down to the present limits of Louisiana (lat. 33° -29°). Along the Rooky Mountains, however, this plant does extend as far southward as lat. 30° ; Mr. Fendler having gathered fine specimens at Santa Fe.

Anemone, Tourn. Inst. t. 147. Willd. Enum. |>. 581. Ledeb. I. c. Wind-Flower.
Calyx of 5 to 20, rarely 4, petaloid sepals, imbricated in aestivation, spreading, deciduous. Petals none. Stamens indefinite, hypogynous : filaments filiform, glabrous : an- thers fixed by the base, rasher extrorse, or innate, the cells opening longitudinally. Pistils numerous (rarely 15 to 20), capitate-imbricated on the globular, conical-oblong, or cylin- drical receptacle (gynophore) : ovary one-celled, one-ovuled : style short, stigmatose from the apex downward along the inner side. Ovule suspended, anatropous ; the raphe dorsal.
Fruit a head of sessile compressed achenia, tipped with the straight or uncinate, short and unchanged or scarcely elongated, naked or woolly styles. Receptacle naked or hairy. Seed suspended from the summit of the cell. Albumen between corneous and fleshy. Embryo minute, next the hilum, cordate : radicle superior.
Herbs, with perennial roots or rootstocks, upright stems, which are simple and naked, except the 3-leaved invo- lucre, and one-flowered, or umbellately several-flowered, or sometimes producing lateral involucellate peduncles from the axils of the involucral leaves, which may again fork or branch at the two-leaved involucel. Involucral leaves usually palmately lobed, or tri - quinately compound, remote from the flower (at the base of the peduncles), resembling the proper or radical leaves. Petioles dilated at the base. Flowers
20 RANUNCULACE^E.
(sepals) commonly showy and white, or tinged with blue or purple, sometimes red.
Etymology. 'Ave/iavrj, the ancient name ; from Svefws, the wind, be- cause the blossom was thought to open only when the wind blows.
Properties. The juice is an acrid poison, as in the foregoing genera.
Geographical" Distribution. Extratropical in both hemispheres, prin- cipally in the northern ; and more than half the 73 known species are in- digenous between the parallels of 40° and 50°, north latitude.

Calyx of 6 to 9, rarely 12, oblong petaloid sepals, imbri- cated in aestivation in two or three rows, spreading, early deciduous. Petals none. Stamens indefinite, hypogy- nous : filaments filiform, glabrous : anthers oval, slightly extrorse, the cells opening lengthwise at or near the mar- gins. Pistils 12 to 20, crowded on the convex summit of the receptacle (gynophore) : ovary one-celled, one-ovuled, apiculate with a very short style, which is stigmatose down the inner side. Ovule suspended from the summit of the cell, anatropous ; the raphe dorsal.
Achenia in a small loose head, at length short-stipitate (in H. acutiloba), ovate-oblong, compressed, not margined, hairy, pointed with the short naked style. Receptacle of the fruit nearly hemispherical, pilose-alveolate. Seed suspended, conformed to the cell, which it fills. Albumen, Embryo, &c, as in Anemone.
Acaulescent dwarf herbs, with fibrous perennial roofs, producing from radical scaly buds, in earliest spring, simple one-flowered scapes, and soon after several 3 - 5-lobed heart- shaped leaves, which become thick or coriaceous in the course of the summer, and last through the winter, until their successors begin to unfold. Vernation involute-plicate.
22 RANUNCULACE/E.
Involucre close to the flower, and imitating a calyx, formed of three ovate and entire sepaloid leaves, rather shorter than the sepals, longer than the head of fruit with its short stalk (the pedicel), persistent. Sepals blue, violet, purple, often pale or nearly white, handsome.
Etymology and Properties. From tiwotikos, affecting or belonging to the liver, on account of a fancied resemblance in the shape of the leaves ; whence, according to the old " doctrine of signatures," it was inferred to be a potent remedy for affections of the liver. It is still a celebrated popular remedy for various diseases ; but it is endowed with no active properties beyond the slight acridity of the recent plant, and a mild astringency with a little mucilage.
Geographical Distribution. Natives of the colder temperate zone of the northern hemisphere, extending northward to the limit of trees. Grow- ing in rich woods, covered in winter by the fallen leaves, above which the handsome flowers rise and unfold almost as soon as the snow leaves the ground.

Calyx of 4 or 5, rarely (in T. anemonoides) 7 to 10, peta- loid sepals, imbricated in a?stivation, spreading or reflexed, caducous or deciduous. Petals none. Stamens indefi- nite, hypogynous : filaments capillary, filiform, clavate, or petaloid-dilated : anthers fixed by the base, strictly innate, various in form ; the cells opening longitudinally. Pistils 3 to 15, crowded on the small receptacle : ovary one-celled, one-ovuled : stigma usually sessile. Ovule suspended, ana- tropous ; the raphe dorsal.
Achenia sessile or stipitate, longitudinally sulcate or many-angled, or inflated (in § Tripterium alate-triquetrous), pointed by the persistent stigma or its base. Albumen be- tween fleshy and corneous. Embryo minute, next the hilum : radicle superior.
Herbs, with perennial, usually fibrose roots, erect stems, and ternately-compound or supradecompound leaves ; the petioles and their branches often auriculate-dilated at the base : leaflets falling away separately by an articulation. Involucre none (the cauline leaves alternate), except in T. anemonoides. Flowers usually small, in compound pani- cles or corymbs, rarely racemose or umbellate, greenish, yel- lowish, or white, seldom purplish, often dicecio-polygamous.
24 RANUNCULACE.«.
Etymology. BaKucrpov, an ancient name, of obscure derivation.
Properties. The roots are scarcely acrid, and often yield a bitter and yellow coloring matter.
Geographical Distribution. This genus, of about 50 known species, is widely distributed through the northern temperate zone ; a few are also found, in a corresponding climate, on the Himalaya Mountains and the equa- torial Andes.
Division. The genus comprises a variety of forms, and greatly needs revision. The North American species belong to three groups, viz. : —
§ 1. Thalictrum proper. — Achenia sulcate-angled, ovoid or oblong, chiefly sessile, the seed conformed to the cell. Stigma elongated. Se- pals caducous, shorter than the stamens. — Roots fibrose. Stems most- ly branching and fistulous, alternate-leaved. Involucre none. Flowers small, mostly panicled, often dicecio-polygamous or strictly dioecious.
§2. Syndesmon, Hoffmansegg. — Achenia and seed as in § 1. Stigma depressed. Sepals 5 - 10, longer than the stamens, merely deciduous. — Root grumous, or fasciculate-tuberous. Stem simple, leafless, except an involucre at the summit, like that of Anemone ; consisting of 2 or 3 trifoliohite leaves with long-petiolulate leaflets, but destitute of com- mon petioles, thus simulating a whorl of 6 or 9 long stalked simple leaves. Flowers few and umbellate, or single, pretty large, showy, perfect.
§3. Physocarpum, DC. — Achenia stipitate, inflated, veiny-striate or even, the cell much larger than the seed. Sepals merely deciduous. — Roots fibrose. Stems usually branching, alternate-leaved. Flowers corymbose, scattered, perfect or polygamous.

Calyx of 3 to 5 orbicular and strongly concave sepals, imbricated in aestivation (when four in number, as is most common, two are exterior and two interior in the bud, but sometimes two are overlapped on one edge by the outer one, and the fourth is interior), petaloid (greenish-white), very caducous. Petals none. Stamens indefinite, hypogy- nous, in several series, much longer than the pistils, all per- fect, white : filaments thickened upward or clavate : an- thers short, pointless ; the elliptical cells separate, some- what extrorsely adnate, opening longitudinally. Pistils indefinite (20 or more), capitate on the short receptacle : ovary compressed, gibbous, one-celled, one-ovuled : stigma recurved, unilateral. Ovule erect, ascending from the base of the cell, anatropous ; the strong raphe ventral.
Achenia capitate, numerous, sessile, broadly ovate, gib- bous, beaked by the recurved-uncinate persistent stigma or short style, utricular and membranaceous, entirely smooth and even, except the four prominent narrow ribs, which are one dorsal, the other ventral, bordering the acute angles, and the two others lateral, forming obtuse angles, the transverse section exactly rhombic : the ripe fruit inclines to open at
one of the sutures. Seed very much smaller than the cell, 3

erect or ascending from next its base at the inner angle, ob- ovate-oblong, smooth. Embryo oblong-linear, fully one third the length of the firm fleshy albumen : radicle inferior, next the hilum : cotyledons narrowly oblong.
Herbs, smooth throughout or nearly so, perennial, with simple, or sparingly corymbose, fistulous stems from matted fibrose rootstocks, few alternate leaves, the upper small and bract-like, and rather handsome corymbose flowers. Radi- cal leaves ample, long-petioled, palmately veined, palmately 5- 11-cleft, with the lobes irregularly incised and toothed; the veins and veinlets conspicuous underneath, freely reticu- lated.
Etymology. Dedicated to E. R. Trautvetter, a well-known botanist, now Professor at Kiev, in Southern Russia.
Geographical Distribution. The original species is found along- shad- ed streams, throughout the Alleghany Mountains from Virginia southward, and along their western confines : it also occurs sparingly in Illinois, and ap- parently reappears in Northern Oregon. A second, but imperfectly known species has been recently indicated by Siebold and Zuccarini in Japan.
Observation. The genus seems to be about equally allied to Thalictrum and to Hydrastis.

9Iouse-tail.
Calyx somewhat petaloid, imbricated in aestivation : se- pals 5, rarely 6 or 7, regular, oblong or spatulate, sessile, the base prolonged downward below the insertion into a pen- dent spur, deciduous. Petals as many as the sepals and alternate with them, smaller than they, hypogynous, raised on a slender claw which is somewhat tubular and nectarif- erous at its summit ; the narrowly oblong lamina plane, not longer than the claw. Stamens 5 to 20, hypogynous : fil- aments filiform : anthers oblong, slightly extrorse, the cells opening longitudinally. Pistils very numerous, or 20 to 25, imbricated-spiked on a prolonged receptacle (gynophore) : ovary inserted by the whole length of the ventral suture, compressed, one-celled, one-ovuled : ovule anatropous, sus- pended from the summit of the cell ; the raphe dorsal : style subulate, as long as the ovary, naked, stigmatose from the apex downward on the inner side.
Fruit an elongated (cylindrical, linear, or oblong) spike of achenia imbricated on the filiform and angled recepta- cle, thickened and somewhat corky in texture at maturity, broadest on the back, which is rhomboidal with thickened edges and a somewhat carinate medial line ; the sides cunei- formly converging to the ventral edge, winch is minutely

hairy, and inserted by its whole length, blunt in M. mini- mus (the short style not enlarging in fructification but incorporated with the back of the carpel), or in M. aristatus, Bcnth., forming a projecting beak. Seed oval, conformed to the cell, suspended from its upper outer angle. Albumen fleshy. Embryo minute, next the hilum, cordate, the short cotyledons separated : radicle superior.
Acaulescent annuals or biennials, small and inconspicu- ous, with narrowly linear and entire radical leaves, and a naked one-flowered scape. Flower small, greenish-yellow : the receptacle very early exserted and prolonged. •
Etymology. Name composed of pis, a mouse, and oipd, tail ; from the appearance of the long spike of carpels in fruit.
Geographical Distribution, &c. The species of the valley of the Mississippi and northwestward, from which our figure is derived, appears not to be distinct from the common European and North Asiatic plant : but a second species, remarkable for its few and aristate carpels, has recently been detected in the Rocky Mountains by Mr. Geyer, as well as on the Andes of Chili.

Calyx herbaceous or slightly colored, imbricated in aesti- vation, regular; the sepals 5 (rarely 3 or 4), concave, decid- uous. Petals 5 (rarely more or fewer), alternate with the sepals, usually much larger than they, imbricated in aestiva- tion, hypogynous, plane, dilated, the contracted base fur- nished on the inner side with a nectariferous depression or small adherent scale, deciduous. Stamens hypogynous, indefinite, rarely few (5 or more) : filaments filiform : anthers short, extrorsely adnate, the cells opening longi- tudinally. Pistils indefinite, capitate on a globular or cy- lindrical receptacle (gynophore) : ovary compressed, one- celled, one-ovuled : style short, subulate : stigma occupying the inner side at its apex. Ovule erect or ascending from the inner angle next the base of the cell, anatropous ; the raphe ventral.

Herbs of various habit and foliage, the cauline leaves, when present, alternate. Petioles dilated at the base. In- volucre none. Flowers solitary, terminating the stem and branches, usually showy, yellow or sometimes white, very rarely purple.
30 RANUNCULACE.E.
Etymology. An ancient Latin name, the diminutive of Rana, a frog, also applied by Pliny to aquatic species of this genus, which inhabit similar places.
Properties. The fresh juice is my acrid and poisonous, so much so in many species as to blister the skin or produce ulcers. But the acrid princi- ple is so far dissipated in drying, that the Buttercups, which abound in every old meadow, are apparently innocuous in the hay.
Geographical Distribution. A genus of about 200 described species, dispersed over almost every paft of the world ; but chiefly belonging to temperate and frigid regions, and to the northern hemisphere.
Division. The white-flowered aquatic species bear a nectariferous pit on the yellowish base of the petal, in place of the adherent scale ; and the achenia are wrinkled transversely ; these form the section Batrachium, DC. The sections Ranunculastrum, Hecatonia, and Echinella, of De I mi- ddle, which all have the squamula on the base of the petals, are distin- guished by characters of less moment, and may rather be taken as subdivis- ions of the higher group, Ranunculus proper.
Note. The genus Hamadryas, which on p. 11 was referred to the Sub- tribe Adonidese, on the authority of the character " ovulo unico pendulo " by Endlicher, has an erect ovule, and must stand nest to Ranunculus ; as is well shown by Dr. Hooker (Flora Antarctica, p. 227. t. 85).

Calyx regular, imbricated in asstivation : sepals petaloid, ovate or oblong, spreading, plane, deciduous. Petals en- tirely wanting. Stamens indefinite, hypogynous : fila- ments filiform : anthers oblong, innate or slightly extrorse, the cells opening longitudinally at the margins. Pistils 5 to 15, sessile on the small or depressed receptacle, one-cell- ed, many-ovuled : style none, or a short point stigmatose on the inner side. Ovules indefinite, occupying the ventral suture in two rows, horizontal, anatropous ; their raphes col- lateral (next the suture, or face to face).
Fruit follicular. Follicles as many as the ovaries, or by abortion fewer, verticillate, or when numerous capitate, soon divergently spreading, sessile, short-pointed, coriaceo- membranaceous in texture, compressed, dehiscent by the whole length of the ventral suture, soon opening flat, bear- ing a row of seeds upon each margin. Seeds horizontal, oval, the smooth and rather thick testa extended into a wing-like border at the raphe and chalaza. Alhumen fleshy. Embryo minute, next the hilum : cotyledons very short, separate.
Herbs smooth, with simple or sparingly branched fistu- lous stems, or scapes, rising from perennial and often creep- ing rootstocks, and bearing several or solitary, terminal , large and showy vernal flowers. Calyx golden-yellow, or rarely white. Leaves ample, rounded, crenate-toothed or entire.
32 RANUNCULACEiE.
veiny, mostly cordate or reniform ; the few cauline or the uppermost nearly sessile, alternate ; the radical ones long- petioled. Petioles dilated and sheathing, and often stipu- liform at the hase.
Etymology. From Ka\a6os, a goblet, in allusion to the golden flower- cup, or calyx, of the common species.
Properties. Somewhat acrid when fresh. The vernal herbage of the common C. palustris is largely used in this country as a pot-herb, under the erroneous, but widely diffused, name of Cowslips: the acridity is destroyed by boiling.
Geographical Distribution. A genus of few species, widely distrib- uted through the colder temperate and frigid zones ot the northern hemi- sphere, inhabiting wet places. — The singular, oligandrous and oligosper- mous, antarctic species are surely of a different genus.

Globe-Flower.
Calyx petaloid, regular, imbricated in aestivation : sepals 5 to 20, orbicular or obovate, remaining incurved, so as to give a globular form to the flower (whence the popular name for T. Europasus), or spreading, deciduous. Petals 5 to 20, hypogynous, small, little exceeding or shorter than the stamens, which they somewhat resemble, ligulate or linear-spatulate, thickish, gland-like, slightly unguiculate, somewhat excavated or tubular on the inner side next the base, deciduous. Stamens indefinite, hypogynous : fila- ments filiform : anthers short, innate, the cells opening lat- erally, or slightly introrse. Pistils 9 to 30, sessile on the globular summit of the receptacle (gynophore) : ovary one- celled, many-ovuled, tapering into a short style ; the stigma unilateral at its summit. Ovules numerous, anatropous, horizontal in two rows occupying the whole length of the ventral suture ; their raphes collateral (face to face).
Fruit follicular. Follicles 9 to 30, capitate, closely sessile, erect or barely spreading, coriaceous, nearly cylindra- ceous, transversely veiny from the dorsal rib, from which is exserted the subulate short style, dehiscent through the ven- tral suture from the apex downward. Seeds horizontal, in two rows, 5 to 10 in each, ovoid or angled : the smooth and
34 RANUNCULACEvE.
coriaceous testa conformed to the nucleus ; the raphe not appendaged.. Embryo minute at the base of the fleshy al- bumen, cordate ; the radicle next the hilum.
Herbs smooth, with much the aspect of Ranunculus ; the mostly simple and fistulous stems rising from fibrose-- fascicled blackish roots, .and terminated by solitary large flowers. Leaves alternate, palmately 5 - 7-parted, with the cuneiform divisions incisely cleft and toothed ; the upper- most nearly sessile. Petioles dilated at the base, and more or less clasping. Flower yellow.
Etymology. Thought to be derived from the German tiollrn, to roll, from the globular shape of the flower in the original European species, the Globe-floioer of the gardens ; — a name by no means appropriate for the other species, in which the floral envelopes are more or less widely expanded.
Properties. Slightly acrid. T. Europaeus, especially, is cultivated for its showy vernal flowers.
Geographical Distribution. Natives of the colder portion of the northern hemisphere, in moist and shady places ; one species in Europe, five in Northern Asia, and one in North America.

Enemion, Raf. in Jour. Pliys. 91. p. 70. Torr. & Gray, 1. c. p. 29. Endl. Gen. 848.
Calyx petaloid, regular, imbricated in aestivation : sepals 5, sometimes 6, spreading, ovate, deciduous. Petals, in species of the Old World, very short and tubular, 1-2-lip- ped, in the North American none. Stamens numerous, hy- pogynous: filaments filiform or flattened : anthers innate, the oblong cells opening on the margins longitudinally. Pistils few or several ; sessile on the globular receptacle : ovary one-celled, pointed with the distinct style, which is stigmatose from the apex down the inner side. Ovules anatropous, few (3 to 10) in a single series and more or less ascending, or numerous in two rows and horizontal, with the raphes collateral.
Follicles 3 to 20 (rarely solitary), membranaceous, veiny or reticulated, more or less compressed, beaked with the sub- ulate style, dehiscent through the ventral suture. Seeds few or numerous, mostly horizontal ; the testa crustaceous, smooth or minutely pubescent, or sometimes granulate-sca- brous. Embryo minute, next the hilum, at the base of the fleshy albumen.
Herbs of small size, with fibrous, and sometimes grumous roots, slender stems, and ternately-compound alternate leaves.
36 RANUNCULACEiE.
Leaflets lobed. Petioles commonly auriculate-dilated at the base, forming a small- stipuliform appendage on each side. Flowers white or light yellow, small or middle-sized, ter- minating the stem and branches.
Etymology and Properties. A name given by Dioscorides to a Gre- cian plant (probably Fumaria eapreolata), formed of 'Irros, equal, and irvpos, wheat. Slightly acrid plants, of no known importance.
Geographical Distribution. A genus of few species, sparingly scat- tered over the northern temperate zone. The two North American species are remarkable for being apetalous : that of the United States has just the aspect of the European I. thalictroides, L. ; while the Californian species is more like the Siberian I. fumarioides, L. Two other species belong to the Altaic and Himalayan Mountains, and a seventh to Japan.
Note. The analyses in Plate 12 having been made from dried speci- mens, with aid of a former sketch in which this point was not particu- larly attended to, we are not sure that the raphe is correctly represented as ventral ; but the ovules, which are only two or three in number, are certain- ly superposed in a single series.

Gold-thread.
Calyx petaloid (white or greenish-white), regular, imbri- cated in aestivation : sepals ovate-oblong or linear, spread- ing, or at length rerlexed, early deciduous. Petals as many as the sepals and alternate with them, hypogynous, unguic- ulate, equalling or shorter than the stamens ; the gland-like apex thickened, cucullate-dilated and inappendiculate, or produced into a filiform caudate appendage much exceeding the stamens. Stamens 13 to 30, shorter than the sepals, hypogynous : filaments filiform : anthers oval, innate, the cells opening longitudinally. Pistils 3 to 10, verticillate, at first short-stipitate or almost sessile and erect, but spreading and the stipe elongating after fecundation : ovary one-cell- ed, several-ovuled, pointed with a short and often recurved style, which is stigmatose down the inner face. Ovules 10 to 24, anatropous, horizontal in two series ; the raphes collateral.
Follicles 3 to 10, ovate or oblong, raised on slender stipes, membranaceous, few- (4- 10-) seeded. Seeds small, horizontal, oval ; the smooth and shining testa conformed or nearly so to the nucleus. Embryo minute, at the base of the albumen, cordate ; the radicle next the hilum.
38 RANUNCULACEvE.
Acaulescent, low and slender, smooth and shining herbs ; with trifoliolate or ternately-decompound radical leaves, on slender petioles, and a 1 - 4-flowered naked (minutely 1 - 2- bracteate) scape, rising in early spring from a kind of scaly bud, borne at the extremity of a long and filiform, extensive- ly creeping, orange-colored, fibrillose rhizoma. Leaves per- sistent through the winter : leaflets incised and toothed.
Etymology. From Kojrra, to cut, alluding: to the divided leaves. Properties. The yellow rootstocks and routs are intensely bitter : the in- fusion is used as a tonic, and as a topical application to aphthous ulcerations. Geographical Distribution. Natives of the colder northern temperate zone, in damp shady woods and bogs. One species extends round the world ; the others are Northwest American and Asiatic.
Division, &c. In a specimen of Chrysocoptis occidentalis, Nutt., from Geyer's Oregon collectfon, the petals are constructed just as in C. aspleni- folia ; that is, the lamina is glandular-thickened and more or less cucullate next the apex of the claw, and then continued upwards into a very long, ligulate-filiform tail ; — thus leaving no real distinction between Chrysocoptis and the section Pterophyllum. Furthermore, the two Japanese species re- ceutly described by Zuccarini resemble the latter, except that their petals are not thus prolonged. It appears, therefore, that only two subgenera can now be characterized, viz.
§ 1. Chrysa.. (Chryza, Raf.) — Sepals oval. Petals very small, glandu- lajform, obconical-dilated and cucullate at the apex, not appendieulate. — Scape 1-flowered. Leaves simply trifoliolate. (C. tnfolia.) ^2. Chrysocoptis. (Chrysocoptis & Pterophyllum, Nutt.) — Sepals linear or narrowly ligulate. Petals with an involute-cucullate lamina, either elliptical and inappendiculate, or produced into a long filiform appendage. — Scape 2 -4-flowered. Leaves 1 - 2-ternately compound.

Columbine.
Calyx petaloid, regular, imbricated in aestivation : sepals 5, spreading, ovate or oblong, deciduous. Petals 5, all sim- ilar in size and shape, hypogynous, inserted by the inner margin or lip of the oblique expanded limb, alternate with the sepals, and produced backwards between them into a long infundibuliform-tubular spur. Stamens indefinite, hy- pogynous, obscurely collected into 5 to 10 clusters : fila- ments filiform and elongated ; some of the innermost abor- tive, destitute of anthers, and converted into membranaceous scales which collectively surround the ovaries : anthers oval, innate, the cells opening lengthwise laterally. Pistils usually 5, sessile, erect or appressed : ovary cylmdraceous, one-celled, many-ovuled : style filiform, elongated : stigma unilateral at the apex. Ovules indefinite, occupying the whole length of the ventral suture in two series, horizontal, anatropous ; the raphes collateral.
Follicles usually 5, sessile, erect and appressed, nearly cylindrical, veiny, tipped with the slender persistent styles, dehiscent through the ventral suture from the apex down- ward. Seeds numerous, in two series, horizontal, small, oval, smooth and shining ; the crustaceous testa conformed to the nucleus. Embryo minute, at the base of the corneous- nVshy albumen, cordate ; the radicle next the hilum.
40 RANUNCULACEjE.
Herbs, with erect and usually paniculate-branching stems, from thickened and fibrose perennial roots ; the alternate leaves bi - triternately compound ; and the large and showy flowers singly terminating the stem and branches. Lower leaves long-petioled ; the uppermost subsessile, or reduced to bracts. Petioles more or less dilated at the base. Leaflets roundish, incisely lobed, glaucous underneath.
Etymology. Name from aquila, an eagle ; perhaps in allusion to some fancied resemblance of the spur-shaped petals (nectaries of the older bota- nists) to talons.
Properties, &e. Rather bitter and astringent, but the seeds are acrid. — The common European Columbine (A. vulgaris, L.) is cultivated in every garden as an ornamental flower ; and our own wild species, which everywhere adorns our rocks and sterile hills in spring, is equally showy, and much more elegant and graceful.
Geographical Distribution. A genus of nearly 30 known species, dis- tributed over the cooler portions of the northern temperate zone. Only one species is indigenous within the proper United States.

Larkspur.
Calyx petaloid, of 5 irregular sepals, imbricated in aesti- vation ; the larger and upper sepal (outermost in the bud) produced backwards from the base into a large hollow spur ; the others plane, spreading, all deciduous. Petals 4, small- er than the sepals, hypogynous, irregular and unsymmetri- cal, in two pairs ; the upper produced backwards from the insertion into spurs which are received into the spur of the calyx ; the lower unguiculate, often with the lamina two- cleft : or all four petals coalescent into one body of irregular form in § Consolida (which is also remarkable for having a single pistil). Stamens numerous, hypogynous, short and included : filaments subulate from a dilated base : anthers oval, innate, the cells opening longitudinally. Pistils 3 or 5, sometimes only one, sessile : ovary one-celled, many- ovuled : style subulate : stigma unilateral at the (entire or two-toothed) apex. Ovules indefinite, horizontal in two se- ries, occupying the whole length of the ventral suture, ana- tropous ; the raphes collateral.
Follicles sessile, chartaceous, pointed with the short style, few -many-seeded, dehiscent down the ventral suture. Seeds in two series, horizontal ; the rather fleshy or spongy 4

testa conformed to the nucleus. Embryo minute at the base of the fleshy albumen : radicle next the hilum.
Herbs, with upright and usually branching stems, alter- nate and palmately five-parted or bi - triternately dissected leaves, and showy flowers, commonly in a terminal raceme or panicle. Petioles dilated at the base. Pedicels often bracteolate. Roots annual, biennial, or perennial, then fre- quently fasciculate-thickened.
Etymology. The ancient name, from 8e\<f>lv, a dolphin ; in allusion to the shape of the flowers.
Properties. Acrid and bitter, especially the seeds. — The active prop- erties are owing to a peculiar principle, called delp/nnia, which especially abounds in D. Staphysagria, L., of Southern Europe. The seeds of this species, under the name of stavesacre, have long been used as a popular remedy against parasitic vermin. — Several very ornamental species of Lark- spur are common in cultivation.
Geographical Distribution. A genus of about 70 known species, dis- tributed throughout the northern temperate zone, chiefly in the warmer and unwooded portions.

Mouk's-Iiood. Wolf 's-bane.
Calyx petaloid, of 5 unequal and irregular sepals, imbri- cated in aestivation, deciduous or marcescent ; the upper one (called the galea) much larger than the others and covering them in the bud, helmet-shaped ; the two lateral broad and rounded ; the two lower smaller and oblong. Petals 2, concealed under the galea, consisting of a very small oblong and emarginate lamina, produced backwards into a short and incurved callous spur, and raised on a very long and slender claw ; the 3 lower minute and resembling sterile filaments, or wanting. Stamens numerous, hypogynous: filaments short, subulate from a membranaceous dilated base, above recurved-spreading : anthers short, innate or slightly in- trorse (extrorse, Ledeb.), the cells opening longitudinally. Pistils 3 to 5, sessile : ovary one-celled, many-ovuled : style subulate : stigma unilateral at the apex, often two- toothed. Ovules indefinite, horizontal in two series, occu- pying the whole length of the ventral suture ; the raphes collateral.
Follicles sessile, chartaceous or membranaceous, oblong, tipped with the short style, many-seeded, dehiscent down the ventral suture. Seeds horizontal, in two series ; the thickened and spongy testa rugose, often appearing as if

squamigerous. Embryo minute, at the base of the fleshy albumen : radicle next the hilum.
Herbs, either erect, reclining, or trailing ; with perennial, often tuberous or thickened and fascicled roots, and simple or branching leafy stems, bearing large and showy flowers in terminal racemes or panicles. Leaves alternate, palmate- ly 3 - 5-parted or cleft; the divisions usually incised or many-cleft. Petioles mostly dilated at the base. Pedicels bracteolate.
Etymology- 'Akovitov, the ancient name ; by some supposed to be de- rived from Acone, a town in Bithynia. The popular name of Monk's-hood is evidently derived from the shape of the upper sepal, especially in the section Napellus ; and that of Wolf's-bane, from the use which was made of some species in Europe for poisoning wolves.
Properties. Deadly narcotico-acrid poisons, especially the root, owing to the presence of a peculiar alkaloid principle, which has been called aco- nita. The leaves of several species have been used in medicine. — Several are cultivated for their showy flowers.
Geographical Distribution. A genus of 30 or 40 described species, natives of the northern temperate zone, chiefly in the colder regions or on mountains. The two species of the United States (namely, A. reclinatum, Oral/, which is nearly white-flowered, and allied to the European A. Ly- coctonum, and A. uncinatum, L.) belong to the Alleghany Mountains, or nearly so.

Shrub Yellow-root.
Calyx colored (dark and dull purple), imbricated in aesti- vation, regular ; the sepals 5, lanceolate-ovate, acute, spread- ing, deciduous. Petals 5, alternate with the sepals and much smaller than they, hypogynous, gland-like, fleshy, rais- ed on a short claw ; the dilated roundish lamina emarginate- two-lobed, the upper face excavated-glandular. Stamens 5, alternate with the petals, or sometimes 10, hypogynous : filaments short : anthers introrse, the elliptical cells sepa- rated below by the thickened connective, opening longitu- dinally. Pistils 5 to 10, sessile : ovary oblong-ovate, one- celled: style subulate, incurved, stigmatosc down the inner face. Ovules a single pair (rarely more?) borne on the middle of the ventral suture, collateral, anatropous, at first horizontal, soon pendulous, and with the raphes ventral.
Follicles 5 to 10, oblong, membranaceous, ventricose- compressed, becoming gibbous by unequal growth, in such a manner that the ovuliferous or middle portion of the ventral suture in the ovary becomes the summit of the pod, and the short persistent style, which marks the original apex,
46 RANUNCULACE.E.
becomes deeply dorsal : ventral suture tardily dehiscent. Seed solitary (by the abortion of one of the ovules), pendu- lous from the apparent summit of the pod, scarcely one fourth its length, oblong-obovate, smooth and even, marked with a narrow ventral raphe. Albumen fleshy. Embryo minute ; the radicle next the hilum.
Shrub low, with long yellow roots and creeping root- stocks, sending up simple or sparingly branched woody shoots (one or two feet in height), which are strongly mark- ed with half-annular scars left from the dilated bases of the fallen (alternate) leaves, terminated by a kind of scaly bud ; from which arise, in early spring, the panicled or compound slender and drooping racemes, and the pinnately 3-7-folio- late leaves ; the former a little precocious, and occupying the base of the branch of the season. Leaflets membranaceous, sessile, ovate or oblong, incised and toothed, often 2 - 3-cleft or parted. Flowers small, numerous, dark purple, sometimes polygamous. Bracts and bractlets subulate, minute.
Etymology and Properties. Name compounded of gavdos, yrlfow, and pi'fa, root ; in allusion to the color of the roots, which, as also the inner bark, wood, and pith, are pervaded with a bright yellow coloring matter, said to have been employed by the aborigines as a dye : it is intensely bitter, and has been used as a tonic.
Geographical Distribution. The single species of the genus belongs to the United States alone, and chiefly to the vicinity of the Alleghany Mountains, growing on rocky and shaded banks along streams.

(or rarely three-) leaved near the summit, and terminated by a greenish-white flower. Leaves rounded-cordate, becoming large (4 to 10 inches broad) after flowering, and somewhat resembling those of the Grape-vine, palmately 5 - 7-cleft, toothed and doubly serrate, veiny ; the upper near the flower and sessile ; the lower petioled. Petioles dilated at the base.
Etymology unexplained. Possibly from vbap, loater, and 8pda>, to act ; in allusion to the medicinal properties of the plant.
Properties much like those of Zanthorhiza. The bitter rootstock is ton- ic, and apparently somewhat narcotic. Its yellow juice was used by the aborigines for dyeing.
Geographical Distribution. The single species is a native of the Northern United States and Canada, in damp woods.

Etymology and Properties. Name from cimex, a bug, and fugo, to drive away ; the Siberian species being employed as a bug-bane. The sen- sible properties are much as in Actasa, but with more bitterness. The Black Snake-root is a famous Indian antidote against the bite of venomous snakes.
Geographical Distribution. A genus of few species, natives of the cooler parts of the northern temperate zone, chiefly in Asia and N. America.
Note. Macrotys should probably rank as a genus ; but Actinospora ap- pears not to be distinguished by characters of equal importance.

Magnoliaceje &. Schizandrace^:, Blume, Fl. Jav. F.ndl. Lindl.
The Magnolia Family, which comprises some of our most ornamental trees, belongs almost exclusively to the eastern side of both continents, and chiefly to the warmer portion of Eastern North America and to the corre- sponding part of Asia. It has no representatives in Europe or in Africa, and none in Western North America. There are some tropical species, on both sides of the equator ; and two genera are extratropical in the southern hemisphere, namely, in South America and in New Zealand and Southern Australia ; but one of them, the Drimys, or Winter's Bark, has a surpris- ingly extensive range ; the same species, according to Dr. J. D. Hooker, extending through 86 degrees of latitude, from near the southern limit of phaenogamous vegetation to New Grenada and even to Mexico !
The family, enlarged as here proposed, so as to include the Schizandreae as well as Wintereae, need be compared only with the order Dilleniaeeae of the southern hemisphere, on the one hand, and with the Anonaceas, on the other. From the former it is absolutely distinguished only by its exarillate seeds, but generally by the trimerous floral envelopes and caducous calyx also. From the latter it is separated by the solid and homogeneous (not ru- minated or lamellar) albumen, and by the imbricated aestivation of the corolla.
An aromatic principle, due to a pungent ethereal oil and its resin, pervades the family. This is most abundant and pure in the Wintereas ; but is also manifest in Schizandra, at least in the fruit and seeds, and not less so in the Magnolieae, although covered by a bitter principle. It is likewise indicat- ed by the minute pellucid dots of the leaves, or at least of the petals, &c. ; and by the " glandular dots or disks " on the woody tissue, which, although comparatively few and minute in Magnolia and Liriodendron, are beautifully marked in Schizandra, — quite as much so, indeed, as in Illicium and Drimys.
54 MAGNOLIACEjE.
\\ hile tlie Winterese, long since separated by Brown, are now generally reunited to Magnoliaceee, the Schizandreae of Blume have been admitted al- most without question as a distinct order, and have even been arranged by Lindley in a different alliance. Yet the latter are at least as nearly related to i lir Winterese as these are to the true Magnolia Family ; and the only absolute character which distinguishes them (namely, the capitate or spiked, instead of simply verticillate or single, carpels) is one in which they accord with Magnoliaceae proper. The stamens are not always monadelphous in Sehizandrea;, nor are the flowers always diclinous, if Hortonia belongs to the group ; while, on the other hand, one of the four Winteraceous genera is polygamous. It appears evident, therefore, either that the Wintereee of Brown should be extended so as to embrace the Scliizandreae, and be ordi- nally distinguished by the total absence of stipules, or else that the whole should be united in one family. Remembering that a few Dilleniacea? have stipules like those of Magnolia, while the rest are exstipulate, and convinced that the sensible properties as well as the floral characters of the plants in question invite the union, I propose to adopt the latter alternative, and to arrange under the order Magnoliaceae these three suborders, as follows.
Subord. I. WINTERED. (Ord. Wintered, R. Br. 1818.)
Flowers perfect, or sometimes polygamo-dicecious. Pistils simply verti- cillate, or reduced to one. Stamens distinct. — Stipules none. Leaves fre- quently verticillate-crowded or opposite, sempervirent, rarely serrate. Bark, seeds, &c., pungent-aromatic. (Ulicieae, DC. Prodr. 1825.)
Illicium. (Plate 21.) Follicles numerous, stellate, 1-seeded.
Subord. II. SCHIZANDRE^. (Ord. ScmzxNimvx, Blume.)
Flowers monoecious or dioecious. Pistils imbricated-spicate or capitate. Stamens in a cluster, monadelphous or distinct (in Schizandra definite). — Stipules none. Leaves entire or toothed. Stems often sarmentose. Muci- laginous, the seeds aromatic. — Spharostemma, Kadsura, and
Schizandra. (Plate 22.) Stamens 5, monadelphous in a 5-lobed disk.
Subord. III. MAGNOLIE.E, DC, Endl.
Flowers perfect, large. Pistils imbricated-spicate on an elongated gyno- phore. Stamens distinct. Seeds in the dehiscent species baccate, and at length hanging by an extensile cord of spiral vessels. Stipules conspicu- ous, forming the teguments of the bud, successively involving the condupli- cate leaves in vernation, deciduous after their expansion, leaving annular- scars on the terete branches. Bitter-aromatic.
Magnolia. (Plates 22, 23.) Carpels coriaceous-baccate, adherent to the receptacle, dehiscent by the dorsal suture. Anthers introrse.
Liriodendron. (Plate 24.) Carpels samaraeform, indehiscent, decidu- ous from the receptacle at maturity. Anthers extrorse.

Star-Anise.
Flowers perfect. Calyx of 3 or 6 petaloid sepals, im- bricated in aestivation, caducous. Petals 9 to 30, imbri- cated in aestivation in 3 or several series, the inner succes- sively narrower, hypogynous, spreading, deciduous. Sta- mens indefinite (12 to 40) in several series, hypogynous, spreading : filaments short and fleshy : anthers adnate, in- trorse ; the two oblong cells contiguous or nearly so, opening longitudinally. Pistils 6 to 18, compressed, crowded in a circle, closely sessile, and broadly inserted around a central short and conical prolongation of the receptacle : ovary one- celled, one-ovuled : style subulate, recurved, stigmatose down the inner edge. Ovule ascending from some part of the ventral suture, anatropous, the raphe ventral.
Fruit a whorl of distinct drupaceous follicles, stellately divaricate, compressed, woody-crustaceous at maturity, when the thin sarcocarp dries up, dehiscent by the whole length of the ventral suture, at length two-valved. Seed ascend- ing from the base of the cell, which it fills, obovate, com- pressed-lenticular, the hilum lunulate ; the crustaceous testa very smooth and shining, brittle (loosely adhering to the ob- scurely sculptured surface of the spongy-membranaceous in-

ner integument). Embryo very minute, at the base of the fleshy and oily, homogeneous albumen.
Shrubs or low trees, entirely glabrous, spicy-aromatic ; the evergreen leaves alternate or irregularly crowded and oppo- site, petioled, oblong, entire, coriaceous, minutely pellucid- dotted under a lens. Stipules entirely absent. Peduncles from axillary or terminal buds, one-flowered. Flower dark red-purple in I. Floridanum, hi the others yellowish.
Etymology. From illicio, to entice; — perhaps from the properties of the Anisette de Bordeaux, which is flavored by the fruit of the Chinese I. ani- satura, the Star-Anise of the shops.
Properties. Spicy-aromatic and carminative, especially the bark, leaves, and fruit. The latter yields a fragrant oil like that of Anise, for which it is substituted. The foliage of the Japanese I. religiosum is said to be poison- ous; and I. parviflorum has the same reputation in Alabama (where it is called " Poison Bay"), probably without good reason.
Geographical Distribution. Of the four known species, two are na- tives of China and Japan, and two of the southeastern extremity of the Unit- ed States.
Note. The buds of I. religiosum, according to the figure and description by Zuccarini, are perulate, and the ovule rises from the very base of the cell. The leaf-buds of I. Floridanum are perfectly naked, green, and acute ; and the ovule is attached to the inner angle of the cell above the base.

Flowers monoecious; the floral envelopes, &c, of the sterile and fertile flowers alike. Sepals usually 5, quincun- cially imbricated in aestivation, sometimes 6, rotund-ovate, concave, membranaceous with rather scarious margins, some- what colored (greenish-white, above sometimes tinged with red), deciduous ; the two exterior smaller.

ovuled, obliquely narrowed into a short beak, which is stig- matose for the whole length down the inner side. Ovules collateral, inserted on the ventral suture above the base, just opposite the lower termination of the decurrent stigma, glob- ular, nearly amphitropous.
Fruit of several (6 to 12, the rest abortive) globular bac- cate carpels, loosely spicate on the much elongated gyno- phore, 1-2-seeded. Seeds superposed when both ripen, hori- zontal, reniform, with a very short raphe in the sinus; the testa crustaceous. Albumen fleshy and oily, homogeneous. Embryo minute, next the hilum : cotyledons very short.
Shrub sarmentose ; with ash-colored bark ; the leaves alternate, ovate, pointed, long-petioled, entire or sparingly denticulate, the teeth glandular-tipped, veiny, thin and mem- branaceous, beautifully punctate with pellucid dots under a lens, deciduous. Stipules none. Buds small, scaly. Pe- duncles filiform, solitary in the axils of the lower leaves of the branch of the season, naked, one-flowered. Flowers small (half an inch in diameter), crimson. Berries red ; the fructiferous receptacle elongating to 2 or 3 inches in length.
Etymology. From <rxi£a, to cut, and di'fjp, for anlhtr ; the disk formed of the united stamens being cleft, as it were, between the anthers.
Properties. Mucilaginous, the fruit and seeds rather pungent-aromatic.
Geographical Distribution. South Carolina to Texas, in damp woods.
Note. The two exterior sepals might be taken for bractlets, and then, when there is a sixth petal, the floral envelopes would be trimerous : but the stamens appear to be uniformly five.

Sepals 3, colored and more or less resembling the petals, spreading or reflexed, early deciduous. Petals 6 to 12, in two to four series, imbricated in aestivation (disposed, along with the sepals, in a regular spiral | order), hypogynous, con- cave, erect-converging, or a little spreading, early deciduous. Stamens indefinite, imbricated in many series upon the stipitiform base of the prolonged receptacle, short, cadu- cous : filaments proper very short, continued into a linear fleshy connective which is produced beyond the anther into a blunt point : anther adnate to its inner face (in- trorse), two-celled ; the cells linear, opening longitudinally. Pistils indefinite, densely imbricated on the upper part of the receptacle (the gynophore) : ovaries fleshy, one-celled, pointed with a short recurved style, which is stigmatose on the inner face. Ovules 2, collateral (rarely 3), borne at the inner angle of the cell, horizontal, anatropous ; the broad raphes face to face : primine thick and fleshy; the secundine thinner.

firmly persistent on the elongated receptacle, at length de- hiscent down the back, two-seeded. Seeds hanging by a delicate, extensile cord of unrolled spiral vessels (contained in the short and fleshy funiculus and placenta), large, glob- ular, drupaceous ; the fleshy testa very thick and at length pulpy (scarlet or bright red); the tegmen bony-crustaceous, widely grooved on the inner side and at the summit (corre- sponding with the broad, impressed raphe and chalaza). Embryo minute, at the base of the fleshy and oily homo- geneous albumen ; the short and thick radicle next the hilum : cotyledons short.
Trees, or sometimes shrubs, with very showy and usu- ally large blossoms and foliage ; the leaves entire, or merely auriculate at the base, feather-veined, deciduous, or some- times persistent through the winter, when thin often indis- tinctly pellucid-punctate, alternate, or by approximation often appearing as if whorled, on stout petioles, which, separating by a distinct articulation, leave broad scars on the otherwise smooth and terete branches. Flowers solitary, terminal, white or greenish-yellow, rarely purplish. Buds terete, acute ; their integuments formed entirely of the ample mem- branaceous stipules : these are adnate to the base of the peti- ole, and involute, with their opposite edges united ; each pair thus inclosing the succeeding conduplicate leaf with the rest of the bud to which it is longitudinally appressed, de- ciduous as the leaves sucessively unfold, leaving their scars upon the branch in the form of narrow rings. Cone of fruit usually red or rose-color at maturity.
Etymology. This superb genus is dedicated to Magnol, Professor of Bot- any at Montpellier at the close of the seventeenth century, and who first indi- cated natural families in botany. — The name was originally given by Plu- mier to a West Indian tree of the order, the type of the genus Talauraa, Juss., and which was confounded by Linnaeus with the allied plants which now bear the name.
Properties. Bitter and slightly aromatic, with some acridity ; the bark, especially of the root, and also the cones and seeds, have been employed as a stimulant tonic. The flowers of some species are highly fragrant.
MAGNOLIACE.E 61
Geographical Distribution. Natives of Eastern North America, and of Eastern Asia, namely of Japan, China, and Nepaul. The seven species of the United States are confined to the vicinity of the Alleghany Mountains, and to the country eastward and southward of them, crossing the Mississippi only near the seaboard. The small Magnolia (M. glauca) occurs along the Atlantic border plentifully as far north as New Jersey, and is also found on Cape Ann, Massachusetts, lat. 424°; while the Cucumber Tree (M. acumi- nata), an inland species, reaches the southern shore of Lake Ontario, which is the northern limit of the genus (a little above lat. 43°). The splendid and fragrant M. grandiflora, belongs exclusively to the low country of the Southern States. The Umbrella Tree (M. Umbrella), which extends northward to Pennsylvania, and the allied M. Fraseri, chiefly belong to moist and wooded valleys along and near the mountains ; while M. cordata and M. macrophylla very sparingly occur in the middle country of the South- ern States. There are, besides, at least two Mexican species.
Note. Our illustrations clearly demonstrate that the baccate exterior in- tegument of the seed is formed of the primine of the ovule ; and therefore is not an arillus ; as so excellent a botanist as my friend, Professor Zuccarini, has endeavoured to maintain,* and as is assumed by Lindley,f and by Endlicher.J

Sepals 3, colored (greenish-white or yellowish), imbricate in aestivation, reflexed, early deciduous. Petals 6, imbri- cated in two series in aestivation, very broad, nearly erect, so as to form a somewhat bell-shaped corolla, hypogynous, deciduous. Stamens indefinite, hypogynous in several se- ries, nearly as long as the petals, deciduous : filaments fili- form : anthers elongated-linear, adnate to the outer face of the connective (c.drorse), two-celled ; the cells contiguous, opening longitudinally. Pistils very numerous, closely im- bricated upon the prolonged receptacle (gynophore) into a fusiform column as long as the petals : ovary sessile by a broad insertion, one-celled, two-ovuled : style laterally winged (or flattened anteriorly and posteriorly), entirely ap- pressed : the stigma unilateral at its summit, cristate, recurv- ed. Ovules collateral, pendulous from near the middle of the ventral suture, anatropous, their raphes face to face.
Fruit a fusiform cone or strobile, composed of the closely imbricated samaraeform carpels, which at maturity fall away from the elongated and bodkin-shaped persistent woody axis :

these are dry and indehiscent, lanceolate, somewhat ligne- ous, consisting of a small, laterally compressed pericarp, which is strongly 4-ribbed ; the ventral and dorsal ribs form- ing the axis, and the lateral ones confluent into the margins, of the large and wing-like obcompressed style. Seeds 2, or by abortion solitary, pendulous ; the thin testa dry and cori- aceous, marked with a narrow salient raphe. Albumen fleshy. Embryo minute, next the hihun ; the radicle superior.
A Tree of large size and elegant aspect ; with the smooth leaves alternate, long-petioled, feather-veined, deciduous, an- gulate-four-lobed, and appearing as if truncate at the apex by a broad and shallow notch. Flowers solitary and termi- nal, very large (greenish-yellow marked with orange), in the bud inclosed by the last pair of stipules in the form of a two- valved caducous spathe. Vernation as in Magnolia, except that the oval stipular buds are compressed and very obtuse, and the leaves are bent down on the petiole so that their summits are brought to the base of the bud. Stipules nearly flat, oblong, obtuse, free from the petiole, deciduous.
Etymology. Name compounded of \ipiov, a lily or tulip, and hivhpov, tree ; from the tulip-like flowers.
Properties. Same as of Magnolia; but the bitter, tonic bark is less aromatic. The light, fine-grained wood is largely used by cabinet-makers, &c, under the name of White-tvood, or White and Yellow Poplar.

The Custard-Apple Family is altogether intertropical, with the re- markable exception of the North American Papaw, which extends even to the southern shore of Lake Eric, and the three allied species indigenous to the Southern Atlantic Slates. The order very closely accords in general structure, as well as in the ternary triple perianth, with Magnoliacese ; from which the valvate aestivation and the ruminated albumen essentially distin- guish it. The sensible qualities, also, are much the same ; but Anonacece have usually less tonic, and more acrid and nauseous properties. The bruis- ed bark and foliage of our Papaw-trees exhale a heavy, disagreeable or fetid odor ; as is likewise said to be the case with the tropical plants of the family which yield a bland esculent fruit.
The presence of an arillus appears to have been first noticed in the order by Prof. Alphonse De Candolle, who proposed to consider its presence as a character of generic value ; and accordingly employed it in distinguishing his Habzelia from Unona, &c. ; also remarking thai this organ was nol known to exist in any Asiatic Anonaceous plant.* Recently, Von Martius has shown that Uvaria Brasiliensis, the only South American species of u hich the fruit has been examined, is likew ise furnished with arillate seeds.f Finally, the examination, last autumn, of fresh fruits of Asimina triloba, en-
" Mem. Jlnonac. I. c. p. 8- 13, A c.

66 ANONACE.E.
abled us to detect a thin and fleshy arillus which completely incloses the ripe seeds; and a dried fruit of A. parviflora exhibits manifest traces of a similar integument.
Our Papaws, therefore, offer an exception to De Candolle's remark, that those Anonaeea: winch have arillate seeds along with a smooth pericarp are always highly aromatic.
I possess no means for determining whether the Asiatic original species of Uvaria are really destitute of such an arillus, which, confounded with the surrounding pulp, might have escaped detection as readily in these as 11 has in the American species. But, without laying stress upon the more or less imbricated aestivation of the corolla in A. triloba and A. par- villora (which is not very distinct in the young flower-bud, and is likely to occur in other cases where the petals are broadly ovate or rounded*), it appears on every ground probable that our species are not congeneric with those of tropical Asia, and therefore that the genus Asimina should be re- stored. To avoid ambiguity, I have drawn its character entirely from our United States species, and principally from A. triloba and A. parviflora (of which alone I have seen the fruit) ; leaving it for future investigation to de- termine whether it is to embrace the few allied South American species, or whether these should be referred to Porcelia, Ruiz 4- Pav., with which they all apparently agree in having their inner petals larger than the outer ; while in ours the exterior petals are much larger than the interior.
The popular name of Papain was doubtless given to the fruit of Asimina triloba from a fancied resemblance in the appearance or taste of the fruit to the true Papaw of tropical America (the fruit of Carka Papaya). Asiminier, from which Asimina was formed, is the name by which the fruit was known among the old French colonists.

The Moonseed Family is a small group, of about sixteen recognized genera and two hundred species, belonging principally to the intertropical regions of Asia and America. There are only three species known in the United States, or, indeed, in all extratropical North America; and these pertain to as many distinct genera. One of them extends northward to Canada; the others are confined to the warmer part of the country.
They are all climbing or twining vines, with woody stems, at least at the base (although our Moonseed dies down nearly to the ground at the north) ; bearing alternate, palmately-veined and usually lobed or angled, often pel- tate leaves, on slender petioles, destitute of stipules ; and with small, dioe- cious or polygamous flowers, borne in axillary racemes or panicles. Their commonly trimerous floral envelopes, of more than two series, which in many cases are not readily distinguishable into calyx and corolla, and the tendency towards indefinite stamens, and more than one pistil, are characters which show the near alliance of Menispermacea; with the foregoing orders, and especially with Anonaceae, some of which have few stamens and pistils ; while the position of the stamens when definite before the petals, with the imbricated pluriseriate arrangement of the floral envelopes, indicates their affinity with Berberidaceaa. They are at once distinguished from both these families by their habit, unisexual flowers, and especially by their large em- bryo in sparing albumen, and the peculiar incurvation of the drupaceous
70 MEMSPERMACE.E.
fruit. The Estivation of the corolla is not valvate, as in the former, nor do the anthers open by valves, as in the latter order.
The nature of the change in form which the ripening ovary undergoes was indicated by Colebrooke, in the Transactions of the Linnaan Society, Vol. 13, p. 51 ; and, subsequently, by Auguste St. Hilaire, in his Flora Brasi/i nsis Meridionalis.
The structure of the wood, which is either zoneless, or destitute of annual layers, is admirably elucidated by Decaisne {Mem. Lardizab. in Archives du Museum).
JMenispermaceae afford both bitter tonic and narcotic principles ; the former principally in the root, of which the officinal Columbo-root furnishes the most important example : the latter prevail in the fruit ; as in the well- known Cocculus-Indicus berries (the fruit of Anamirta Cocculus), employed for poisoning fish and beer. These contain two venomous principles, name- ly, the deadly picrotoxine in the seed, and menispcrmine in the pericarp.

Etymology. From the Cocculus Indicus of the shops, an old name (form- ed from coccum, a berry) adopted by Bauhin. But the plant that yield;- the officinal fruit which gave its name to the genus, as now received, has unfor- tunately been excluded from it, and forms the genus Anamirta.
Observations. The essential character given above has been made to conform to the genus as received by Colebrooke. The English description is drawn wholly from our own plant; which seems, however, to be truly congeneric with several Indian species, as it probably is with South Ameri- can ones : but I have not seen the illustration of Chondodendron convolvula- ceum, Pbpp. It is a pity that the name of Cocculus was not kept for the plant yielding the officinal fruit so called ; in which case, one of the names applied to American species, cited above, would have taken due precedence for the present genus, whither it were found to embrace the bulk of those of the Old World or not. At all events, it will doubtless comprise none which present the character " cotyledones distantes," assigned by Be Candolle ; although apparently it should include C. sepium, Cokbr., with foliaceous cotyledons, as well as C. Plukenetii, DC, with fleshy and semicyhndrical ones.

Embryo in the axis and about two thirds the length of the fleshy albumen, which it almost separates into two thin plates, very thin and foliaceous, concave so as to conform to the shape of the albumen, slightly pointed at the radicular apex, which is also flat, divergently two-lobed at the other extremity, thus heart-shaped. Its peculiar form is evidently due to the lateral junction by their contiguous edges of the cotyledons, which were laterally separated like those of Ana- mirta Cocculus.
Vine woody, climbing or twining : with alternate and ex- stipulate palmately-veined and 3 — 5-lobed membranaceous leaves (the lobes acuminate, sometimes wavy-toothed), cor- date at the base, on long petioles. Flowers small, greenish- white, in racemose panicles: peduncles supra-axillary, slender.
Etymology. From xdXuJ, a hush, or covering, or fluwer-cvp, and Kapiros, fruit ; a name evidently meant to designate the cup-shaped she]] of the fruit.
Geographical Distribution. The single known species belongs to the Southern States west of the Alleghanies.
Note. A genus manifestly allied to Anamirta, and also to Cocculus crispus. DC, judging from the analyses given by Colebrooke.

The Barberky Family, well marked as it is by the imbricative arrange- ment of the floral envelopes, and the stamens in a ternary, or sometimes bi- nary or quaternary order in two series of each set, so that the petals taken together stand opposite as many sepals, and the stamens likewise opposite these, — and also by the valvular dehiscence of the anthers, and the single pistil, — yet presents the following exceptions, in plants which, nevertheless, certainly belong to this order. 1. The anther-cells open by a longitudinal line in Nandina, and also in Podophyllum. 2. In Podophyllum peltatum (but not in P. hexandrum) the stamens are twice the number of the petals. 3. In Achlys the stamens are indefinite, the ovule solitary, and the floral envelopes altogether wanting (just as in Trochodendron, Zucc, among Magnoliaceas Wintereae). 4. In Jeffersonia, the sepals (4 or 5 in number) form a single series, and are fewer than the petals.
The position of the petals and definite stamens in Menispermacese is, of course, to be explained in the same manner as in the Barberry Family ; and this arrangement is not to be confounded with the different case of Vitaceas, &c, where a single series of stamens is opposed to a simple whorl of petals.*
" The difference has been pointed nui by .Vlr. de Jussieu, Cours Elem />'«' ■ 386, 794
78 BERBERIDACEJE.
The close alliance of the Berberidaces to the preceding orders is admitted by all botanists, perhaps, except Dr. Lindley, who has at length proposed a widely different arrangement, which is evidently based upon peculiar grounds, by no means compatible w-ith ordinary views of botanical affinity.*
The family consists of about 12 genera, all of few or single species, ex- cepting Berberis itself, distributed over the northern temperate zone, chiefly in the cooler parts, and extending southward along mountain ranges only. In America the genus Berberis is also represented at the southern extremity of the continent. The berries are usually acid and edible or harmless ; the foliage is often acid ; the bark and roots of the woody species are astringent, and the roots of one or two are drastic.
The compact wood of Berberis trifoliolata exhibits very broad medullary rays, much wider, towards the circumference of old stems, than the woody wedges themselves, which fork sparingly, after the manner of some Aristo- lochias. The annual layers are indistinct. Young stems of Nandina exhibit a similar structure.

" Veg. Kingd. p. 432-445. — In his Berberal alliance, Dr. Lindley com- bines, as the nearest allies of BerbcridiLcew, the DroseracetB, Fumariticete, Vita- cur, Cyrillacea, Ac. He excludes, however, frum the Barberry Family the ge- nus Podophyltums " which some botanists fency should stand here "; — a fancy which originated with Mr. Brown, ami which does not appear extraordinary when that genus (and especially its hexandrous species) is compared with Jef- fersonia and Diphylleia.

Barberry.
Calyx calyculate with 3 or sometimes 2 close-pressed bractlets : proper sepals 6, in two series, alternatively im- bricated in aestivation, orbicular or obovate, concave-spread- ing, more or less petaloid, deciduous. Petals 6, opposite the 6 sepals, imbricated in aestivation in two series, hypogy- nous, obovate, concave-connivent, unguiculate or sessile, marked with two thickened glands, or more or less conspicu- ous glandular spots, at the base of the lamina inside, decidu- ous. Stamens 6, hypogynous, opposite the petals and short- er than they : filaments thick, articulated with the recep- tacle, spreading under the petals in the expanded flower, starting forward towards the pistil with a sudden jerk when touched with a point next the base on the inner side (thus projecting the pollen upon the stigma): anthers two-celled; the cells somewhat extrorsely adnate to the thick connec- tive, nearly the whole face separating as a valve which is lightly hinged at the apex. Ovary ovoid, one-celled, mark- ed with a projecting placental line inside (toward the axis) : style short and thick or none: stigma orbicular and peltate, umbilicate, entire. Ovules 2 to 9, erect from the base ol the placental line, towards which (he raphes are all turned
80 BERBERIDACE.-E.
Berry oblong or globular. Seeds 1 to 9, erect, oblong, with a crustaceous testa and a narrow raphe. Embryo in the axis and occupying nearly the whole length of corneous- fleshy albumen, straight or nearly so : radicle slender, infe- rior : cotyledons elliptical, fiat and nearly foliaceous, parallel with the raphe, shorter than or equalling the radicle in length.
Shrubs, with yellow wood and inner bark, deciduous or persistent 1 - many-lbliolate alternate leaves ; their petioles dilated at the base. Stipules adnale, commonly minute, caducous. Leaflets articulated, veiny, usually spinulose- toothed or ciliate-serrate. Flowers yellow, racemose.
Etymology. From the Arabic name of the berries of the Barberry. Properties. These well-known berries are pleasantly acid and astrin- gent. The yellow bark and wood furnishes a dye, and is astringent, and seems also, with the root, to contain a principle (berberine) which is cathartic. Division. To the two recognized subgenera, I may here add a third. § 1. Bereeris proper. — Filaments usually inappendiculate. Primary leaves mostly converted into triple, quintuple, or simple prickly spines ; the secondary fascicled in the axils of these, unifoliolate (articulated above the scale-like base which represents the real petiole), subsessile.
§2. Trilicina. — Filaments inappendiculate. Unarmed: leaves all evo- lute, digitately 3-foliolate : leaflets sessile on the apex of the common petiole. (B. trifoliolata, Moric.)
§3. Mahonia, Nutl. — Filaments appendiculate with two salient teeth at the apex. Unarmed : leaves all evolute, pinnately 5 - 17-foliolate.

Petals 6, hypogynous, one at the base of each sepal and very much shorter than it, fleshy and gland-like, viscid, unguiculate, cuneiform-dilated, the very broad and rounded summit involute, deciduous. Stamens 6, hypogynous, opposite the petals and rather shorter than they: anthers rather shorter than the filaments: the two oblong cells somewhat extrorsely adnate to the thickish con- nective ; the greater part of the face separating in dehiscence as an uplifted valve. Ovary ovoid-oblong, one-celled, taper- ing into a subulate oblique style, which is minutely stigma- tose from the apex down the inner side. Ovules 2. collat- eral, erect from the base of the cell, raised and as if articu- lated on short fleshy funiculi, anatropous.

shrivelling away. Seeds (one or both maturing) therefore naked, stipitate on their thickened funiculi, spherical, large, with a fleshy at length baccate testa, appearing like drupes ! Albumen corneous, deeply umbilicate at the hilum, its verti- cal section deeply reniform. Embryo minute, partly received into a sort of cup formed by the folding of the tegmen in the axis of the umbilicate basal depression, cylindrical : radicle short, inferior, about the length of the thick cotyledons.
Herbaceous ; the fleshy rootstock sending up in early spring a simple and naked stem, bearing near the summit a triternately compound leaf destitute of a common petiole, and often a smaller and similar leaf at the very base of the ter- minal raceme or panicle. Leaflets 2-5-cleft at the apex, glaucous, as also the blue drupaceous seeds.
(Characters from the North American species only.)
Etymology, &c. Leontice is a name abbreviated by Linnaeus from the Leontopetalum of Tournefort. Caulophylluin, which may very probably re- sume its generic rank, is formed of Kavhos, stem, and tfiCWov, leaf; the stem seeming to form a stalk for the single, large and compound leaf.
Properties- The root is an " Indian medicine," but its real qualities are unsettled. The albumen of the seed has been proposed as a substitute for coffee.

Emrryo in the axis of the albumen, extending from the base nearly to the middle, slightly curved to correspond with the curvature of the seed: radicle inferior, slender ; the coty- ledons nearly of its length, oblong, pretty thin, parallel with the raphe.
84 BERBERIDACE^E.
Herb of striking appearance, with much the habit of Po- dophyllum : the thickened and creeping rhizoma formed of distinct annual increments, sending up a stout alternately two-leaved flowering stem (terminated by a cyme of white blossoms), which separates at the base in autumn by a marked articulation, leaving a broad excavated scar, in the manner of the rootstocks of a Solomon's Seal. Leaves very large (1 to 2 feet broad when full grown), thin, palmately veined, reticulated, of dilated reniform or orbicular circum- scription, deeply two-cleft, and the margins cut-lobed and toothed ; the cauline excentrically, the radical centrally, pel- tate on long and stout petioles. Berries blue, glaucous.
Etymology. From Sir, twice, or double, and divXkov, leaf.
Properties. Unknown: probably much like those of Podophyllum.
Geographical Distribution. Restricted to shaded springy places, or the margin of mountain brooks, in rich and deep alluvial soil, along the Al- leghanies from Virginia to Georgia. It (lowers in May, while the leaves are yet but half grown.

Ovules indefi- nite, borne in several rows on nearly the whole length of the broad ventral suture, somewhat ascending, anatropous.
Fruit a coriaceous obovate pod, transversely dehiscent half-way round on the back, near the summit, by a revolute persistent lid, forming a broad lunate chink. Seeds numer- ous in several series on the broad placenta, somewhat as- cending, arillate; the arillus unilateral at the base of the raphe, fleshy, laciniate : testa coriaceous.

spring, a tuft of two-parted peltately-veined radical leaves, on long petioles, and naked scapes terminated by a single white flower.
Etymology. Dedicated by Professor Barton to Thomas Jefferson.
Properties. The plant has a popular reputation in Ohio, under the name of Rheumatism-root, as a stimulant, diaphoretic, &e. (Riddell, Synop- sis.) The seeds have an acrid taste, which is very persistent.
Geographical Distribution. The single species inhabits rich and cool woods, from Northern New York southward through the Alleghany Moun- tains, and in the Western States.

May-Apple. Mandrake.
Calyx (calyculate by 3 green bractlets which are cadu- cous before anthesis) formed of 6 very thin and membrana- ceous obovate sepals, imbricated in two series in asstivation, caducous from the bud without expanding. Petals 6 or 9, in two or three series, alternatively imbricated and slightly crumpled in aestivation, hypogynous, dilated-obovate, large, spreading, deciduous. Stamens as many as the petals and opposite them in the Himalayan species, twice as many in the North American, hypogynous : filaments very short : anthers oblong-linear, adnate ; the cells opening longitudi- nally by a single extrorse line, as it were by a laterally hinged valve. Ovary ovoid, sessile, one-celled, crowned by a large and thick peltate and undulate-crested stigma. Ovules very numerous, covering the broad ventral placenta which occupies the whole length of the cell, crowded in about 5 rows, horizontal, nearly amphitropous.
Fruit a large ovate fleshy berry ; the cell filled by the lateral placenta and the mass of pulpy arilli developed from its whole surface, inclosing the indefinite obovate seeds. Embryo small, at the base of fleshy albumen.
Herbs, with thick fibrous roots from creeping rootstocks, which send up in spring sterile stalks terminated by a single orbicular centrally peltate leaf, or two-leaved stems termi-

runted by a single large (white) flower, nodding on a short peduncle. Cauline leaves excentrically peltate, palmately 5 — 9-ribbed and deeply cleft : the lobes incised and toothed.
Etymology. Name formed of 7ro0s , a foot, and <f)v\\ov, leaf; from a fancied resemblance of the leaves to the feet of a web-footed bird.
Properties. The mawkish fruit of the May-Apple is edible, and is said by Dr. Griffith to resemble that of Passiflora edulis in taste as well as in ap- pearance : the herbage is poisonous : the root is a drastic cathartic.
Geographical Distribution. Our species (from which the above de- tailed character is drawn) is indigenous nearly throughout the United States : and there is another (P. hexandrum) in the mountains of Nepaul.
Note. The arillus was detected by Prof. Torrey several years ago, and is noticed in his elaborate Flora of the Slate of New York, 1. p. 35. The floral envelopes are first correctly described in my Ma/ma! of the Botany of the Northern States, in the Errata, p. 4. A singular discrepancy in respect to the size and shape of the embryo is shown on the annexed plate. As the fruit does not ripen in Eastern New England, we have been unable to mul- tiply observations upon this point.

Calyx of 4 broadly oval and nearly herbaceous sepals, imbricated in two series in sestivation (two exterior and two interior), persistent. Petals none. Stamens 4, hypogy- nous, one opposite each sepal : filaments stout : anthers shorter than the filament, obliquely introrse, fixed by the middle, the oval or oblong cells opening by a longitudinal line down the inner side. Ovary ovate-globose, one-celled, tipped with a depressed and entire sessile stigma. Ovules 3 to 6, attached to the apex of a filiform placenta which is adherent to one side of the cell for the whole length, thus suspended, anatropous.
Fruit globose-ovate, apiculate ; the dry pericarp coria- ceous, tardily two-valved from the apex ; the valves parallel with the inner sepals. Seeds mostly 2, suspended each by a short filiform funiculus, globose-oval, marked with a slen- der raphe terminating in a broad apical chalaza, covered, ex- cept the chalazal end, with a wig-shaped arillus composed of copious slender and fleshy threads. Embrjo next the hiluin in fleshy albumen, minute, globose-ovoid, obscurely two- lobed (if we mistake not) at the cotyledonar extremity.
Herb low and slender, from a horizontal creeping rhizo- ma. Stem simple, provided with two or three alternate 7
90 bekbeuidaci:-!:
sheaths at the base, then naked to the summit where it bears 4 to 6 alternate and approximate or irregularly fascicled leaves, on slender petioles, and filiform peduncles in their axils. Leaves thin and membranaceous, cordate at the base, ovate-oblong, acuminate, entire, 5 - 9-ribbed, the ribs con- verging to the apex, and connected by copious transverse re- ticulated veinlets, as in Smilax or Dioscorea. Flowers 2 to 3, very small, greenish-white or tinged with purple. Pedi- cels subtended by small alternate bracts, slender, articulated above the middle ; the summit becoming thickened in fruit.
Etymology. The genus consists of a single species, dedicated by Pro- fessor Torrey to the memory of his friend, the late Hardy B. (''room, Esq., the discoverer, who was also the author of a Monograph of Sarraceniu , and of other botanical papers.
Geographical Distribution. The plant grows in woods in Middle Florida, where it has been gathered by Dr. Chapman, as well as by the la- mented botanist whose name and services to science it commemorates. Mr. Buckley has also detected it in Alabama.
Note. For our knowledge of the ripe fruit, discovered since the first volume of the Flora of North America was published, we are indebted to Dr. Chapman and Mr. Buckley. Our analyses are taken partly from sketch- es made by Dr. Torrey, and kindly furnished for our use. We discovered the minute embryo in a single seed only, and are not certain whether it is dicotyledonous or not. In either case, the affinity of the genus remains ob- scure.

The Water-shield Family, which it is most convenient to regard as a separate order, is nevertheless only a simplified form of Nymphaeaceae, as has always been maintained by Mr. Brown,* — the pistils of Brasenia being to that of Nymphaea just what those of Platystemon, Benlh., are to, that of a Poppy. Viewed as distinct, it should stand between Ranuneulaceaa and Nelumbiaceae ; but it is only from an overestimate of the external charac- ters that it has been proposed to merge it in the former instead of the latter order. The seed and embryo exhibit precisely the peculiar structure of those of the Water-Lilies, as our illustrations clearly show.
The figure copied by Lindley ( Veget. Kingd. p. 412) is either taken from an unripe seed of Cabomba aquatica, in which the cotyledons are not full- grown, and the walls of the inclosing sac are vastly thicker than afterwards ; or else, which is more likely, the cotyledons have been mistaken for the sac, and the plumule for the entire embryo. In the accompanying section of the carpels, after Turpin, the ovules are placed on the wrong suture.
The anomalous attachment of the ovules to the dorsal suture of the ovary, first noticed by Mr. Brown in Brasenia, and recorded in his notes made upon the living plant in New Holland, which he had the kindness to show me,

is also explicitly mentioned by Salisbury, in 1806,* and by Nuttall, in 1818.
The last-named author has also well described the circularly disposed air- tubes, &c, of the stalks of Brasenia ; which, however, are constructed near- ly as in the stems of most aquatics ; except that they are said by Schleiden and Lindley to be entirely destitute of spiral vessels.
The two genera of which the group consists are both represented in the United States, to which and to Eastern New Holland ! Brasenia is confined ; while Cabomba is divided between the Southeastern United States and the eastern side of South America near the equator.
The roots and herbage of these plants are mucilaginous, with some as- tringency. They are entirely destitute of acridity and of any noxious qualities.

Sepals 3, or sometimes 4, narrowly oblong, imbricated in aestivation, herbaceous, colored inside, persistent. Petals as many as the sepals and alternate with them, hypogynous, linear-oblong, sessile, not appendiculate, persistent. Stamens 12 to IS, or sometimes more numerous, hypogynous : fila- ments filiform : anthers linear-oblong, innate, the cells opening longitudinally by a slightly introrse line. Pistils 4 to IS, capitate-crowded, sessile : ovary oblong, one-celled, terminated by an oblong and brush-shaped introrse stigma of almost its own length. Ovules 2, superposed on the dorsal suture, pendulous, anatropous ; the raphe towards the suture.
Fruit (few or several of the carpels maturing) indehis- cent, coriaceous, pointed with the persistent stigma, oblong or obovoid, usually only one (the upper) seed ripening. Seed ovoid, large ; the crustaceous testa nearly smooth. Albumen farinaceous, marked by a central canal, as in Ca- bomba. Embryo depressed-globular, filling the membrana- ceous sac which occupies and is partly imbedded in the hilar extremity of the albumen: radicle a mere papilla at the junction of the two very thick and lleshy cotyledons, which lie parallel with the raphe (or anterior and posterior), and in- close an oblong two-lobed plumule.
96 cabombacejE.
Herb growing in ponds and pools, sending up, from a fleshy prostrate rhizoma, long and forking stems bearing above alternate oval and entire centrally peltate leaves, invo- lute in vernation, brought by the elongation of the petioles to the surface of the water, on which they float. Peduncles axillary, equally elongated, bringing the solitary dull purple flower to the surface, where it expands only in anthesis. The stalks and other submersed parts are covered, especially when young, with a thick coating of transparent jelly.
Etymology. Brasenia is unexplained ; perhaps it was designed to com-* memorate some obscure German botanist. Hydropeltis, which, being un- fortunately the later name, must give precedence to that imposed by Schre- ber, is the Greek equivalent of Water-shield.
Geographical Distribution. The single species is abundant through- out the United States and Upper Canada. It is most remarkable that what appears to be the same species is also a native of Eastern New Holland, where it was long ago detected by Mr. Brown !
Note. The jelly by which the stalks, &c, are thickly coated, I find to arise from the rapid formation and rupturing of successive epithelial cells, in the same way that mucilage is formed on the surface of animal mucous membranes. The rhizoma of Brasenia contains oblong and transversely an- nulated starch-grains of unusual size, the larger being 6^3 of an inch in length.

The Water-Lily Family is the first of the series which exhibits a truly compound pistil, formed by the union of a whorl of carpels into one syncar- pous ovary. It also furnishes instances of the partial cohesion of the floral envelopes with each other, and especially with the surface of the compound ovary. It likewise affords the finest examples of the gradual transition of sepals into petals, and of petals into stamens ; as in the White Water-Lily, in which every intermediate gradation may be traced between the naked pe- tals and perfect stamens of the ordinary structure and appearance. Both the petals and stamens are numerous, or indefinite, and imbricated in several series. The pistil consists of several (six to fifteen or more) cells ; that is, of as many carpels, vertieillate and coalescent in a solid mass around a cen- tral axis.
A remarkable characteristic of this family is found in the insertion of the ovules. These are scattered over the whole face of the dissepiments, that is to say, " the whole internal surface of the carpels is equally ovuliferous," instead of the inner angle or suture only, as in all ordinary cases. Indeed, the inner angle of the cells in Nymphsea and Nuphar is the only part of the surface which is not ovuliferous, or scarcely so. The tendency to produce ovules is greatest towards the middle and posterior part of the parieties, and (in Nuphar) at or near the dorsal angle itself. This fact, viewed in con- nection with the circumstance already mentioned under Cabomba (p. 93), namely, that one of its ovules is often found attached to the wall of the cell
100 NYMPHiEACEjE.
at some distance from either suture, affords the completest confirmation of Mr. Brown's remark upon this subject.*
Our analyses clearly demonstrate that the embryo in Nymphaeaceas and in Cabombaceae is just that of Nelumbium on a smaller scale : the difference being that the albumen has been absorbed into the latter, which has taken a further development ; and that the amniotic sac has disappeared, or become confluent with the coats of the seed, unless, indeed, it may be identified with the diaphanous membrane which surrounds the plumule. The state of our fresh specimens of Nelumbium, transmitted to us at midsummer from a great distance, forbade an investigation of this and other points, which a botanist who has the growing plant before him might prosecute with success.
Besides Nymphasa and Nuphar, the order comprises three exclusively tropical genera, namely, Barclaya of Pegu, Euryale of Northern India, and the superb Victoria of Guiana and Northern Brazil, the most gigantic of water-plants, its orbicular peltate leaves being from six to eight feet, and its fragrant blossoms often fifteen inches, in diameter ! f
These plants are destitute of noxious, or any active properties, excepting a moderate astringency. The stalks are also mucilaginous ; and the farina- ceous seeds are edible, as likewise are the thickened rootstocks of some spe- cies, when cooked.
* " A case of this kind is found in a portion of one of those families in which the whole surface is generally ovuliferous, namely, in Hydropeltideae, which I have always regarded as a mere section of Nymphceaceae; and from the nature of these differences in placentation, which are more apparent than real, an ar- gument might even be adduced in favor of that opinion.'

This group consists of two genera of American Pitcher-plants ; namely, Sarracenia of the United States and Canada, of which five or six species have long been familiarly known ; and Heliamphora, Benth. , founded on a plant which Mr. Schomburgk gathered on the mountain of Roraima, in Brit- ish Guiana. The latter differs from the type of the family in bearing several flowers in a raceme on the bracteate scape, in the total absence of the caly- culus, of petals, and of the peculiar umbrella-shaped summit of the style which is so remarkable in Sarracenia, and also in having the seeds sur- rounded by a wing.
Unfortunately, this accession does rot appear to throw any new light upon the affinities of Sarracenia, which are still obscure, notwithstanding that Dr. Planchon * has recently pointed out some striking points of resemblance be- tween this genus and Pyrola, which in his mind leave no doubt of their im- mediate affinity.
The pitcher or open tube of the leaves evidently belongs to the petiole, which is also simply winged or margined along the inner side ; while the blade is represented by the hood, or rounded appendage at the apex, which cannot be called a lid, as it never closes the orifice, nor is it so much incurv- ed as at all to cover it, except in two speices. This proper lamina is rudi- mentary in Heliamphora, and very small in proportion to the ample orifice, which extends some way down the inner side: and thence a double wing- like border extends to the base, appearing just as if the two margins of an

infolded leaf were united by a seam, so as to leave the free edges outside. In Sarraeenia this wing or margin is simple and entire. The pitchers, espe- cially those of S. purpurea, are generally found partly filled with water and dead Hies with other small insects. Whether the water is secreted by the leaf itself, or caught from the rain, is still undetermined. The point might readily be ascertained by proper observations, made especially upon S. psit- tacina, the pitchers of which are so protected by the hood that the fluid they contain (if any) can hardly be supposed to have entered by the orifice. That the water in the open pitchers of S. purpurea is not secreted by the internal hairs, as Dr. Lindley and Mr. Bentham suppose,* would appear from the fact, that the younger leaves are empty, and that during the spring and summer it is those of the previous season, from which these hairs (in this species very long and delicate) have mostly disappeared, which alone or principally are found to contain water.
But, however derived, this water serves to drown the flies and other in- sects, which these leaves are admirably adapted to catch and retain. Ac- cording to Elliott and others, there is a saccharine exudation at the throat of the Southern species which attracts insects ; but this is not noticeable in S. purpurea. Immediately below the surface it is very smooth and polished, and still lower it is beset with sharp hairs, in most species long and slender, or else like those of the hood (in S. Drummondii extremely short and close), but in all pointing directly downwards so as to allow insects to descend, but effectually to obstruct their return. The inner surface of the hood is like- wise lined with stiff and sharp retrorse bristles, which subserve a similar purpose, except in S. flava, which is smooth ; but in that species this ap- pendage is erect, with its sides turned away from the mouth of the tube, which thus it bears no part in guarding.
An anatomical investigation of the leaves is still a desideratum.
The six described species of Sarraeenia are all restricted to the Atlantic border of the United States, from Virginia southward ; except S. purpurea, the range of which extends from Florida to Newfoundland, and northwest to Ohio.

Herbs of singular aspect, growing in bogs and marshes ; with fibrous roots from a short perennial rootstock, produc- ing trumpet-shaped or pitcher-shaped coriaceous colored and reticulated leaves, and a naked scape terminated by a large (yellow or purple) nodding flower.
Etymology. Dedicated to Dr. Sarrazin, of Quebec, who sent the north- ern species to Tournefort. The origin of the popular name, Side-sadd/e Flower, is not evident. From the shape of the leaves, the common species is called Huntsman's Cup; and the tubular leaves of S. flava, &c. , are call- ed Trumpets in the South.

The Poppy Family is usually known, among the hypogynous polyan- drous and polypetalous orders, by its milky or colored, and narcotic or acrid juice ; the usually alternate and lobed or divided leaves without stipules ; the caducous calyx of only two or three sepals ; the early deciduous petals of twice, thrice, or some higher multiple of the same number, imbricated and commonly crumpled in aestivation, and by the one-celled compound ovary, composed of from two to twenty carpels, with as many parietal placentae, which usually separate from the edges of the valves of the capsule in dehis- cence. The anatropous seeds are frequently crested at the raphe ; and the embryo is small or minute at the base of the copious fleshy and usually oily albumen. They are principally annuals. One genus, Dendromecon of Cal- ifornia, alone is shrubby : and a most remarkable anomaly is presented by another Californian genus (Platystemon, Bcnth.), which has a cluster or whorl of apocarpous pistils !
The family consists of about 19 genera, none of which is numerous in species except Papaver itself. Much the larger part of the order belongs to the South of Europe and the adjacent portion of Asia. Another focus is found in a country of very similar climate, namely in California, to which, and to the regions adjacent, seven or eight of the genera are peculiar. One or two perennial Poppies alone are arctic, and constitute the only represent- atives of the typical genus in the New World. Chelidonium, the Celan- dine, is a common weed around dwellings, but has been introduced from Europe. It is remarkable that, among our numerous weeds, imported with grain, &c, the Corn-Poppies of the Old World have not found a place, ex- cept in one or two local instances.
110 PAPAVERACE.E.
The well-known narcotic properties of the Poppy pervade the order, ex- isting in the milky or colored juice ; which, however, is extremely acrid rath- er than narcotic in some genera, as in the Celandine. The oily seeds of the Poppy are bland and wholesome : but those of the Prickly Poppy are said to be acrid and noxious.
Most Papaveraceaj have showy flowers, and many are cultivated for orna- ment ; particularly the Poppy itself, and Eschscholtzia.
The three genera which alone are indigenous within the United States proper, namely, Argemone, Stylophorum, and Sanguinaria, scarcely require a conspectus.

112 PAPAVERACE/E.
Herbs of a glaucous appearance, with annual, biennial, or rarely perennial roots, branching stems beset with prickly bristles and abounding with a yellow juice, and alternate pinnatifid-incised sessile leaves, which are often mottled with white along the midrib ; the lobes and teeth spinulose- pointed. Flowers terminal and solitary, short-peduncled or subsessile, not drooping in the bud (as in the Poppy and most of the allied genera) : petals yellow or white.
Etymology and Properties. Name said to be derived from dpye/ia, a disease of the eye ; the acrid juice being a native ophthalmic medicine. The seeds share in the active properties of the plant ; and are employed in the West Indies as a substitute for Ipecacuanha, and in South America as a purgative.
Geographical Distribution. The few species are natives of tropical America and, apparently, of the southern border of the United States ; but A. Mexicana has been from an early period widely diffused over the world.

terminal 2-3-valved buds, a long-petioled leaf and a naked one-flowered scape. Leaf roundish, palmately 5 - 9-ribbed and obtusely 5 — 9-lobed, reticulated-veiny, wrapped around the flower-bud when it rises from the ground, much en- larged after expansion and becoming reniform. Flower large for the size of the plant, handsome : petals white.
Etymology. Name from sayiguis, blood, in allusion to the color of the juice, which flows copiously from the rootstock or petioles when wounded.
Properties. An acrid narcotic, the former quality prevailing ; of con- siderable importance and promise in the materia medica. The active prop- erties appear to be principally due to a peculiar, extremely acrid alkaloid principle, called sanguinarina. The juice was used by the aborigines as a paint or dye ; and hence, like several other tinctorial plants, it was called Puccoon.
Geographical Distribution. Common, in rich woods, throughout the United States and Canada. •

The Fumitory Family accords so nearly with Papaveracea? in the struc- ture of the fruit and seeds, that these plants were included in that order by Jussieu, and are still regarded by eminent botanists as forming merely a di- vision of it with irregular flowers. Indeed, of the botanists who receive the family as distinct, some admit Hypecoum and its allies to form a component part of it (as does Lindley, notwithstanding his removing the family to another alliance than that which contains the Poppy Family), while others exclude them. According to the latter view, which is manifestly to be adopt- ed when (from considerations of convenience chiefly) the family is kept dis- tinct, Fumariaceaj are to be characterized by the irregular 1 - 2-spurred or saccate corolla, the four connivent petals of which, or at least the two inner, are more or less coherent ; and by the diadelphous stamens, placed three in each set before the exterior petals, with dimorphous anthers ; the central one of each set being two-celled, while the lateral are only one-celled and but half the size. The anthers with the stigma remain inclosed in the little, cavity formed by the cohesion of the spoon-shaped tips of the two inner petals, which never open. The bitterish or slightly acid and watery (instead of colored or milky) juice is not diagnostic : for it is quite the same in Esch- scholtzia and other undoubted Papaveraceae, which apparently are equally destitute of any narcotic quality.
To account for the nature and position of the four stamens with one-celled anthers, De Candolle suggested that these result from the fission of the two stamens of the inner series which (in the regular symmetry of the binary flower) should stand before the inner petals; — a view which was reproduced
118 FUMARIACE^.
by Lindley (Inlrod. to Nat. System, ed. 1, etc.). On the other hand, M. Gay has recently maintained,* that these are the four normal stamens of a complete inner verticel, while two of those of the outer vertic'el (with 2-cell- ed anthers) are wanting, and that the flower is therefore really hexandrous and with the same arrangement as in Cruciferas. The objection to this view is, that it presupposes a truly quaternary, instead of a binary, plan of the flower.
Taking a still different view, I presume that the lateral stamens in this case will be found to arise by the process called " didoubhment " by the French botanists (happily translated deduplication by Mr. Henfrey) ; — a mode of increase in the number of ■parts, particularly of the stamens, which must be allowed to occur in analogous cases, if the observations of Duchatre were accurately made, and which is not at all incompatible with received morphological views ; for a single phyton may as readily give rise to a clus- ter of stamens as to the several leaflets of a digitate leaf.
The two sepals are anterior and posterior and the carpels lateral (right and left as respects the axis), just as in Cruciferse ; hut, by the torsion of the pedicel in flower, the carpels, with the outer petals to which they corre- spond, appear to be anterior and posterior.
As to sensible qualities, Fumariaceas are slightly bitter and astringent, or with the tubers, &c, a little acrid ; but of no especial importance.
This small order, with the exception of two species indigenous to the Cape of Good Hope, belongs entirely to the temperate zone, and chiefly to the Old World. One species of the genus Fumaria (which gives its name to the order, although it is a greatly simplified form, as to the fruit, which is reduced to a one-seeded nutlet) is sparingly naturalized around old gar- dens and dwellings in the Northern States. The indigenous representatives of the family in North America, scarcely a dozen in number, are restricted to three genera ; namely, Dicentra and Adlumia, with both of the exterior petals gibbous or saccate at the base, and Corydatis, in which only one of them is saccate or spurred.

Calyx of 2 very small petaloid or scarious sepals, resem- bling bractlets, never inclosing the flower-bud. Corolla cordate, or two-spurred at the base, compressed, hypogynous, of 4 connivent but distinct petals in two series ; the two exterior larger, alternate with the sepals, similar, saccate or calcarate at the base, appressed, inclosing the inner pair ex- cept their midribs and apex, contracted above, and with short and spreading hooded tips : the two interior opposite the sepals, unguiculate, spoon-shaped or excavate-hooded at the apex, where the two lightly but permanently cohere over the anthers and stigma, their prominent midrib dilated at the sum- mit to form a salient crest : all deciduous, or else scarious-per- sistent around the base of the pod. Stamens 6, in two sets of three each, one set opposite each outer petal and lightly cohering with its insertion and with a linear (or sometimes nearly obsolete) gland that descends into the spur or sac : filaments subulate-filiform, distinct, or the three slightly united, especially about the middle : anthers more or less extrorse, fixed by the base, that of the middle stamen two- celled, those of the lateral one-celled ; the cells opening lon- gitudinally. Ovary one-celled, with two parietal placentas

placed opposite the inner sepals : style subulate or filiform : stigma crest-like, flattened contrary to the placentae, 2 - 4- lobed or horned. Ovules numerous, horizontal in two rows on each placenta, between amphitropous and anatropous.
Capsule siliquaeform, lanceolate or oblong, membrana- ceous ; the two valves separable from the filiform interval- vular placentas, which remain with the persistent style. Seeds several, globular-reniform, with a shining crustaceous testa, conspicuously crested at the hilum. Embryo minute, at the narrowed base of I he fleshy albumen next the hilum.

ent filiform intervalvular placental;. Seeds globular-reni- form, with a smooth and shining crustaceous testa, partly covered by a concave or shell-shaped hilar crest. Embryo minute, at the smaller curved extremity of the fleshy albu- men, next the hilum : cotyledons as long as the radicle, foliaceous and lanceolate in germination.
Herbs with slender or simple roots (no tuberous caudex), often biennial or annual ; the stem more or less branching, and with ternately or pinnately compound or dissected leaves. Racemes terminal, or becoming opposite the leaves, bracte- ate, often yellow or purple.
Etymology. An ancient name for the "crested lark," and for some plant of the Fumitory family, which probably took the name from the spur of the flower, somewhat like that of the Larkspur.
Geographical Distribution, &o. Natives of the northern temperate zone, much the greater part Siberian. The two species in the United States, with one on the Pacific coast, belong to the genus as restricted by Bernhardi, whose view it is therefore most convenient to adopt.

The Mustard or Cress Family, one of the most strictly natural and homogeneous which the vegetable kingdom affords, is at once distinguished by its regular cruciform flower, tetradynamous stamens, and by that sort of pod termed a siHque, or, when very short, a silicle.
The flowers are formed on the quaternary plan. There are always four sepals, of which the two exterior in the bud are situated one anterior and the other posterior, while the two interior, which are often the larger, are lateral, or right and left, as respects the axis of inflorescence. Although the edges of the outer pair cover those of the inner in the bud (except in the few instances where the aestivation is valvate), yet the plan of the flower is not binary, like that of Fumariaceae (p. 117), but the four sepals constitute a single verticel ; for the four petals are alternate with them, instead of being opposed to them, as would necessarily be the case on the former supposi- tion. The laminae of the four petals, spreading opposite each other in pairs, produce the cruciform shape which gives the name to the order. In aestiva- tion, the petals are imbricated with usually one exterior, two half exterior and half interior, and the fourth wholly interior, or else they are regularly convolute ; the latter mode being only a slight deviation from the former. Both the calyx and the corolla are deciduous in all the family, or at least in all ordinary cases.
126 CRUCIFER.t:.
The peculiarity of the stamens gave the name and character to the class, Telradynamia, which in his Artificial System Linnaeus framed for the recep- tion of these plants. Of the six stamens, two are shorter and inserted one opposite each lateral sepal ; while the four longer, which are commonly in- serted a little higher on the receptacle or hypogynous disk, are placed one pair before the posterior, and the other before the anterior sepal. This brings them partly before the four petals respectively ; which has not unnat- urally been taken to be their normal position by several botanists, as by Kunth,* and Gay,f who thus view them as forming the complete inner stamineal verticel, and consequently suppose that half of the exterior verticel (namely, the two stamens which should stand before the anterior and poste- rior sepals respectively) has been suppressed. But it is plain, as our dia- grams (Plates 53, 54, 63, &c.) show, that these four stamens are not oppo- site the petals. As already remarked, they stand in pairs before the anterior and posterior sepals, or alternate, with the two upper and two lower petals, that is to say, just in the places which should be occupied by single stamens to complete the symmetry of the tetramerous flower. In other words, the anterior and posterior stamens of the simple verticel are doubled, just as the two stamens of Fumariaceae are trebled, by deduplication.
This explanation, as applied to Fumariaceae, was in type, as it now stands (on page 118), when, just in the nick of time, I received the London Jour- nal of Botany, for January, 1848, containing a beautiful elucidation of the Structure of Cruciferous Floicers, by Prof. Moquin-Tandon and my friend P. Barker Webb, in which this view is brought forward and enforced in a much more thorough and convincing manner than. I could have hoped to do- it. % To the instances cited by them in which one or both of these stamens

t "De Candolle, himself, has shown in his Memoir on Crucifera, that each pair of geminate stamens has really only the value of a single organ, and con- sequently that the andrceceum in Cruciferae may, like the corolla and calyx, be reduced to the quaternary type."
" This theory of the didoubhment of the two longer stamens in this group is confirmed by numerous facts, both normal and anomalous. 1. In many Cru- ciferee, and more particularly in the Clypeola cyclodontea, Del., the filaments of the solitary stamen are furnished with two teeth, one on each side, whilst those of the double stamens have but one on their outer side ; if we join these two stamens together, so that they form but one, a bidentate filament will result en- tirely similar to those of the solitary stamens.
" 2. In other Cruciferffi a longer or shorter portion of the filament remains simple. Thus, in the Sterigma tomentosum, DC, the division takes place as tar as the middle; in the Anchonium Billardieri, DC, in a third part only of the upper portion of the filament. Here the position of the longer stamens, double only in their upper portion, is exactly the same as that of the solitary stamens.
" 3. In the Vella psendocytisus, Linn., we find, in the place of the double sta- mens, a single one: its filament being frequently rather broader, sometimes di- vided only at its summit, sometimes entirely undivided, but bearing in that case an anther, wholly or partially geminate.
"4. Many Crucifcrae become tetrandrous by pclorization, others are normally so. In either case, the four stamens are then equal.
CRUCIFERAE. 127
habitually or frequently remain undivided below, we may add the genus Streptanthus (Plate 61, fig. 4). Although these able botanists do not allude to the analogous case of Fumariaceae, yet it is perfectly evident that they would apply the same principle to the explanation of the anomaly in that family. The six anthers are all alike and two-celled.
The gynsecium consists of two united carpels, which stand right and left as respects the axis of inflorescence, or one before each of the lateral sepals. The peculiarity of the silique consists in its being two-celled, while the pla- centae are strictly parietal. The explanation of this long since indicated by Brown, and by Lestiboudois, is doubtless the true one ; namely, that the false dissepiment is an extension of the parieties of the carpels, or, so to say, of the epicarp of each, stretching inwards beyond their ovuliferous edges, so as to form, sometimes a narrow border, as in Selenia (Plate 67), &c , but commonly a perfect partition by their union in the centre. The line of junction is frequently indicated by a median nerve (Plates 53, 55, 57, 64). This partition, however thin, is separable into its two component la- mella;, composed apparently of a single stratum of compressed cells, which are of different forms in different plants. Besides this areolation, the par- tition is sometimes veiny, or traversed, more or less copiously, by " tubes having the appearance and ramification of the veins of a leaf." These dif- ferences were pointed out by Mr. Brown, and turned to account in distin- guishing genera.* We have endeavoured to figure the principal forms of areolation which are presented by the species we have illustrated ; but are not prepared to offer any opinion respecting the value of this character.
In several Cruciferae, this partition is altogether wanting, especially in the Isatideae, where the pod is indehiscent and only 1-2-seeded, and in Cakile (Plate 74) and its allies, in which the pod is transversely divided and joint- ed. In the dehiscent genera, the two valves always separate from the fili- form placentae, which form the frame (rcphtm) for the partition, and bear the persistent style or stigma.
The styles, if any, are always consolidated into one. The two stigmas are either combined, or more or less distinct (2-lobed) ; and the lobes are anterior and posterior, or are placed over the parietal placentas, and not over the cells; just as happens in most Papaveraceae, and in many other cases of parietal placentation. This, along with the abnormal partition and dehis- cence, gave rise to some ingenious hypotheses respecting the structure of the Cruciferous fruit, which need not be here recounted, since their foundations
"5. Finally, certain Cruciferae, instead of returning to the quaternary type, recede from it. Their single stamens undergo a change analogous or very sim- ilar to that of the double pair. One of us lias observed flowers of Matthiola in- cana, in which the single stamens were cleft throughout their entire length each portion being provided with half an anther and half a filament. M. Lesti- boudois speaks of a Cheiranthus Cheiri in which these stamens were completely geminated, not laterally as the longer pair, but from without inwards. M. Se- ringa met with a flower of the same species (var. grandiflora) which had the lower stamens ' didoubldes ejartcment comma les sup&rieures.' " — Moq.-Tand. tfc Webb, in 1. c. p. 5, and p. 6, 7.

have been entirely swept away by Mr. Brown's masterly exposition of the real nature and composition of the stigma, as well as of the placenta.* In this family the two half-stigmas of different carpels are combined over the placentae, just as those placentae are themselves formed by the junction of the contiguous edges of two different carpellary leaves, that is, of the two half-placentae of different carpels. As applied to Cruciferse, this view has just been very satisfactorily reproduced by Moquin-Tandon and Webb, in the article before cited, and entirely de novo on their part, as they were un- acquainted with Mr. Brown's exposition of this subject until after their arti- cle was prepared for the press.
The structure of the flower and fruit in this strictly natural family is so uniform, that it is unnecessary to repeat continually, in our detailed descrip- tions, the characters which are common to the whole, or to which there are few if any exceptions ; such, for instance, as the alternate leaves (to which Dentaria offers the only exception) ; the indefinite racemose inflorescence ; the absence of bracts and bractlets (of which the exceptions are noted where they occur) ; the introrse 2-celled anthers ; the aestivation of the calyx and corolla, which as to the former is imbricated with the anterior and posterior sepals outside, as already mentioned, in all our genera ; and, as to the lat- ter, the same genus or even the same individual exhibits both the imbri- cated-convolute and the truly convolute modes.
As at present known, this family comprises at least 1600 species, under about 180 genera. Cruciferous plants are found in every part of the world, but are most abundant by far in the northern temperate zone. There is a larger proportion in the Old World than in the New.
The sensible properties of the order are exemplified by its familiar escu- lent and officinal representatives, such as the Mustard, Horseradish, Radish, Cabbage, Turnip, Scurvy-Grass, &c. All have more or less of the volatile acrid principle upon which their stimulant, rubefacient, and antiscorbutic qualities, as well as the pungent flavor, depend. Diffused among abundance of saccharine and farinaceous or mucilaginous matter, this acridity serves as a wholesome natural condiment. Some Cruciferae, like the Rape, are culti- vated for the fixed oil that abounds in the embryo of the exalbuminous seeds. Many are prized for the beauty or fragrance of their flowers ; as the Wall- flower, Stock, &c
In a local Flora, it is most convenient to characterize the primary divisions from the fruit, whether dehiscent, indehiscent and nucamentaceous, or lo- mentaceous. In a general system, some characters taken from the seed and embryo should doubtless have precedence ; but it is still uncertain which should take the lead. For the present purpose it will suffice to dispose our comparatively few genera according to the following conspectus.

Seeds indefinite and usually very numerous, occupying two rows in each cell, on irregularly crowded capillary free funiculi, more or less pendulous, flattish, rounded, impressed-punctate. Radicle ascending on the side towards the axis (remote from the pla- centa) ; the cotyledons accumbent, plane, parallel with the partition.
132 CRUCIFER^E.
Herbs growing in water or wet places, smooth or simply hirsute ; with annual, biennial, or perennial roots, and branch- ing stems which are frequently rooting below. Leaves usu- ally lyrately toothed or pinnatifid, or pinnately parted ; the petioles often auriculate-dilated at the base. Flowers small or minute, yellow or white ; the racemes prolonged in fruit.
Etymology. An old name for several pungent Cruciferous plants, said to be compounded of nasus and tortus, from their effect upon the nostrils.
Geographical Distribution, &c. A cosmopolite genus, the species of which are of difficult extrication, especially those of the section Brachylo- bos, DC, which have for the most part yellow or yellowish flowers. The Water-Cress is the type of a peculiar section of the genus (Cardaminum, DC). While many species bear linear siliques, others by gradual transi- tion have oblong, elliptical, ovoid, or even globular silicles, some of which C. A. Meyer therefore refers to Cochlearia § Armoracia. Indeed, the white- flowered N. lacustre, Gray, ined.,* is so exactly an Armoracia as to con- vince me that that group, if it can be detached from Cochlearia, will have to be appended to the present genus ; — which, taken as a whole, would be more naturally placed among Alyssineae than in Arabideae. — The Ameri- can N. palustre (which usually has shorter pods than the European plant) sometimes exhibits 3 - 4-carpellary and completely 3-4-celled ovaries.

(which is the Cochlearia amphibia, ft. Mryer) ; the white petals are twice the length of the calyx, and there is no partition to the pod, except a narrow border.

138 CRUCIFERjE.
Etymology, &c. Name from dens, a tooth ; in allusion to the rhizoma, which is beset with tooth-like processes (the rudiments or vestiges of leaf- stalks) in most species : these are very strongly marked in our D. diphylla ; which is commonly called Pepperroot, from the pungent taste (much like that of Water-cresses) of its coral-like rootstock. The proper English pop- ular name is Toothwort.
Geographical Distribution, &c. A genus (scarcely distinct from Cardamine) of about twenty known species, natives of the northern temper- ate zone. Five species belong to trie United States ; two of which are widely diffused, while the others are local or rare. — The species chosen for our illustration is the least known of all. Mr. Nuttall described it from un- usually luxuriant specimens, which he found " in the western parts of the State of New York and Pennsylvania.'' It has since been gathered only at Watertown, New York, by the lamented Dr. Crawe (in whose untimely death by drowning, since our drawing was made, Botany has lost a most as- siduous devotee) : but none of the specimens are so tall and leafy as Nuttall describes, nor do they deserve the name of D. maxima.

Etymology and Geographical Distribution. Dedicated to Dr. M. C. Leavenworth, the discoverer of one species, if, indeed, L. aurea is distinct from L. Michauxii, the Cardamine uniflora, Michx. These little plants grow on wet rocks, &c, in Eastern Kentucky, Tennessee, and Alabama : also in Arkansas. .
Note. The embryo in this genus exhibits a remarkable " arrest of de- velopment," of which there is no other example in the family. In the fully ripe seeds, the cotyledons remain straight, in the same line with the radicle, just as in the half-grown embryos of other Cruciferae, or else (in L. Mi- chauxii, Torr.) the cotyledons are slightly inclined to one side, so as to manifest barely a disposition to become accumbent.

Note. The arrangement of the species is not yet well settled. The North American A. Canadensis and A. laevigata, with the Siberian A. pen- dula (Sect. Catolobus, C. A. Meyer, or Lomaspora, DC. excl. sp.), have winged seeds, with their funiculi partly adnate to the partition, the elongat- ed areolae of which are bounded by exceedingly tortuous lines (just as in Plate 59, fig. 6), the petals small, the style very short or none, and the ovules biseriate in each cell ; and certainly ought not to be separated from Turritis.

Treacle-Mustard. False Wall-Flower.
Calyx erect ; the sepals equal, or the lateral ones gibbous at the base, and sometimes appendiculate or cornute at the apex. Petals unguiculate, the slender claw erect, the di- lated oblong or roundish lamina spreading. Glands 4. Fil- aments subulate or filiform, toothless : anthers linear -oblong or elliptical, often sagittate. Ovary linear, not stipitate : style mostly short and thick : stigma capitate or two-lobed. Ovules numerous, forming a single row in each cell.
Silique linear, usually long and slender, and exactly four- sided (the cross section square or rhombic), with four sharp and nearly similar angles, two of them the projecting placen- ta?, the others formed by the strong nerve which occupies the middle of each carinate (and rather coriaceous) valve : partition nerveless. Seeds numerous, pendulous on fili- form or setaceous free funiculi, forming a single row in each cell, oblong, turgid or somewhat three-sided, not margined. Cotyledons plane, oblong, thickish, parallel with the pla- centae and incumbent on the ascending radicle, which oc- cupies the side remote from the placenta and is sometimes oblique.
Herbs, chiefly biennials, more or less scabrous with closely appressed rigid hairs, which are two-parted (appear-
150 CRUC1FER.E.
ing like a single bristle fixed by the middle), or stellately 3 - 5-parted ; the stems virgate, leafy. Cauline leaves linear or lanceolate, entire or merely toothed, sessile or short-peti- oled, never dilated and auriculate or clasping at the base ; the radical sometimes runcinate-pinnatifid. Raceme elon- gated in fruit, ebracteate. Flowers yellow, often showy.
Etymology. 'Epio-ipov, an ancient name, thought to conic from epva, to draiv blisters, in allusion to the acrid properties.
Geographical Distribution. A pretty large European, and especially North Asiatic genus, of which there are several Western N. American species, but only two or three this side of the Rocky Mountains (excepting E. cheiranthoides, which was doubtless introduced from Europe). The species here illustrated alone crosses the Mississippi, Mr. Sullivant having long since detected it in Central Ohio.
Note. The areolatiun appears to vary considerably in different species. In E. Arkansanum, the uniform amorphous areolae are bounded by very tor- tuous lines, much as in Turritis. In this species and its near allies, also, the radicle is often oblique, or the cotyledons, in part, almost accumbent.

Etymology. Dedicated by Mr. Nuttall to Lord Stanley, who was dis- tinguished as an ornithologist and patron of natural history.
Properties. These plants differ from the rest of the family, and resem- ble Capparidaceee (to which they approach somewhat in structure) in their nauseous and emetic qualities. (Vide Nuttall, I. c.)
Geographical Distribution. The genus was established on S. pinna- tifida (the Cleome pinnatifida, Pursh, first gathered on the Upper Missouri by Bradbury), of which Mr. Nuttall gave an admirable description ; a sec- ond species from the base of the Rocky Mountains was detected by Dr. James, and two others were subsequently found in the same region by Nut- tall himself. The genus is restricted to the Rocky Mountains, except as to the original species, which descends the Missouri for a great distance.

Calyx equal, colored (purplish or greenish-white) ; the sepals linear or spatulate, soon spreading. Petals un- guiculate, the elongated claws exceeding the calyx, loosely spreading, bearing a dilated cuneiform-spatulate or nearly orbicular lamina, often with minutely erose-undulate mar- gins, in aestivation either convolute, or with one petal entire- ly external. Stamens rather slightly tetradynamous : fila- ments almost capillary, much exserted : anthers linear- oblong, spirally revolute when dry. Glands of the dilated torus 4, conspicuous in pairs in front of the shorter stamens.

Cotyledons narrowly oblong, thickish, plane, sometimes parallel with the placenta and incumbent on the ascending radicle, which rests on the middle of one of them, or is exactly dorsal, sometimes oblique and at the upper part parallel with the partition, so as there to be nearly or quite accumbent.
Herbs, entirely glabrous, with annual fibrous roots, and slender upright and branching stems, bearing numerous spat- ulate-oblong or ovate-oblong entire leaves, which are nearly sessile or partly clasping, and handsome rose-purple or white flowers in abbreviated umbel-like racemes, the rachis of which scarcely elongates in fruit ; the slender pods recurved- spreading or pendulous. Bracts none.
Etymology. Dedicated by Nuttall to Mr. N. A. Ware, who collected one species in Florida.
Geographical Distribution. A genus of two closely allied species of Georgia and Florida, allied to Stanleya, and especially to Thelypodium, Endl. (Pachypodiuin, Nutt.), with which, as our figures show, it frequently ac- cords in having the cotyledons oblique, so as to become almost accumbent.

Calyx nearly equal at the base, colored (yellow); the sepals loose or spreading, oblong-linear. Petals spatulate, spreading, tapering into a claw nearly as long as the calyx. Stamens shorter than the petals : filaments filiform, tooth- less : anthers oblong, emarginate at both ends. Glands 10, yellow, of which 8 form an outer series, one before each sepal and petal, and two thicker ones stand one before each of the shorter stamens (opposite the valves of the pod). Ovary oblong, turgid, contracted at the base but scarcely stipitate, two-celled, or only one-celled, the partition being imperfect : style filiform, much longer than the ovary : stigma depressed-capitate, entire. Ovules several (6 to 10) on each placenta, horizontal, on long and filiform free fu- niculi, forming two rows in each cell.
Silicle broadly oval, much compressed parallel with the very broad partition, slightly margined, abruptly subulate with the long persistent style, contracted into a slightly stipitiform base ; the valves membranaceous, flattened, or when young slightly turgid, minutely veiny, nerveless ; the broad partition very thin, complete or fenestrate, sometimes reduced to a mere border not wider than the filiform or ca- pillary free funiculi ; the areola: irregular and bounded by
158 CRUC1FER.-E.
nearly even lines. Seeds 4 to 8 on each placenta, horizon- tal, or toward the summit pendulous, forming two rows in each cell, orbicular, flat, surrounded by a firm and rather broad wing, the cavity extended into a kind of pouch or CEecum next the hilum on the lower or placental side, into which the embryo does not extend. Cotyledons orbicular, flat, parallel with the partition, accumbent against the radi- cle, which is very short and ascending, or nearly horizon- tal, on the side remote from the placenta.
Herb annual or biennial, low, smooth, branching from the base, leafy, terminated by racemes of pretty large, yellow flowers ; the leaves runcinate-pinnatifid : the filiform pedicels subtended by foliaceous bracts like the leaves.
Etymology. From o-(\i)vr), the moon ; a name chosen to express the near relationship of the genus to Lunaria.
Geographical Distribution. Only one species is known (unless the form with the partition obsolete should prove distinct), which grows in damp prairies of Arkansas and the adjacent part of Texas.
Note. The areolae of the partition are said to be linear and transverse by Torrey, in Ann. Lye. Nat. Hist. New York, 3. p. 94, and in the Flora of North America, 1. c. (which would lie like those of Lunaria rediviva) ; but in our specimens, which, however, all belong to the variety with an incom- plete partition to the pod, they are seldom more than oblong, and in great part oblique or vertical, as represented at fig. 7. The singular pouch just below the hilum gives to the seed so exactly the appearance of being resu- pinate, as in Cremolobus, that it was thus described in the Flora of North America, 1. c, and a distinct tribe accordingly established for its reception. But the radicle lies on the other side, as shown in our analyses ; and the genus therefore belongs to Alyssinese, next to Lunaria.

Ovules numerous, horizontal or pendulous in two rows in each cell ; the funiculi adnate more or less to the partition.
Silicle globose-inflated, sessile on the receptacle, or some- what stipitate : the valves hemispherical and membrana- ceous, or strongly convex and nearly coriaceous, nerveless : partition (rarely imperfect) broad, orbicular or broadly obo- vate ; the areolae (in V. Engelm. ) oblong or linear, sinuous, directed towards the axis. Seeds 4 to 12 in each cell, in two rows, on filiform funiculi which are adnate to the parti- tion for a part of their length, orbicular, compressed, often margined. Cotyledons flat, parallel with the septum, ac- cumbent : the radicle ascending on the side remote from the placenta.
162 CRUC1FER.E.
Herbs low and spreading or tufted ; with entire or repand, rarely pinnatifid, narrow leaves, usually canescent or hoary with close stellate pubescence ; the showy yellow flowers in ebracteate terminal racemes.
Etymology. Name from vesica, a bladder; in allusion to the inflated or bladder-like silicles.
Geographical Distribution. A genus of a very few South European species, of one subarctic American, and about a dozen other known species (several of which are yet undescribed) belonging chiefly to the region be- tween the Mississippi and the Rocky Mountains, the greater portion Texan Only one species (V. Shortii, Torr. <Sf Gr.) is found east of the Mississippi.
Note. The section Physaria, Nutt. in Torr. Jir Gray, Fl. 1. c, found- ed on V. didymoearpa, Hook., now confirmed by a second species (V. Gey- eri, Hook.), must surely be raised to the rank of a genus, distinguished from Vesicaria, and differing from the character of Alyssineae, by the strongly di- dymous silicle with a narrow partition.

transversely folded upon themselves, instead of being up- wardly bent upon the radicle at their very base.
Herb small, aquatic, with a tuft of annual fibrous roots, from which rise clustered terete and elongated-subulate loosely cellular leaves, and naked scapes, bearing a raceme of few and minute white flowers.
Etymology. Name formed from subula, an awl ; in allusion to the shape of the leaves.
Geographical Distribution. A genus of a single species, indigenous to the colder parts of the northern temperate zone, growing on the gravelly margins of lakes and pools, where it is ordinarily covered with water. In the United States this little plant has as yet heen detected only in the State of Maine, where it was gathered long ago by Nuttall* and recently by Tuck- erman and by Oakes. Probably it is not local, however, but has escaped notice in the North from its size and the place of growth as much as from its rarity.

The Caper Family is nearly related to Cruciferse on the one hand, and to Resedaceae on the other. It resembles the former in sensible qualities, as well as in the usually cruciform flowers, and in the structure of the ovary (of which even the spurious partition connecting the parietal placentae is sometimes met with) ; and likewise in the dehiscence of the pod in all the capsular genera, in which the two valves separate more or less completely from the intervening filiform placenta;, just as in Fumariaceae. The sta- mens, also, are commonly six in the Cleomete, that is, in all the capsular- fruited Capparidaceae, but are not tetradynamous. In the Capparece, or proper Caper Tribe, with baccate fruit, the stamens are often indefinite, and the placentas sometimes several in number. Several genera of this tribe are apetalous.
The pungency and stimulant qualities of the Caper Family are owing to an acrid principle, much like that of Cruciferae, which gives the flavor to the well-known condiment, the capers of commerce, which are the pickled flower- buds of C'apparis spinosa. This pungent principle is often so concentrated as to be dangerous; and is accompanied with other active, or even narcotic qualities, which render many species more or less poisonous or medicinal.
Capparidaceae are chiefly found in the tropics, and the countries bordering on them. The common Caper, however, inhabits the Furopean shore of thi Mediterranean, and, in the New World, one or more West Indian spe- 12 •

cies of the genus have barely reached the eastern coast of the peninsula of Florida, or the adjacent " Keys," which have a proper West Indian and tropical vegetation. The few species of extra-tropical North America be- long to four or five genera of the Tribe Cleomere, DC, and are all Southern and Western, with the exception of Polanisia graveolens, which extends northward and eastward to the Great Lakes and Lake Champlain. Gynan- dropsis pentaphylla has most probably been introduced by the negroes into the Southern States ; so that the genus does not properly deserve a place in this work.

Etymology. An early name, said to come from /cXa'u, to dose.
Geographical Distribution, &c. A somewhat polymorphous genus of numerous species, belonging to the warmer parts of the world. One spe- cies is found in Portugal, and two or three extend northward to about the same latitude in North America west of the Mississippi.
Note. In C. integrifolia, a species scarcely distinct from C. serrulata (the type of Atalanta, Null., or Peritoma, DC), of which I have no speci- mens, the somewhat dilated summit of the torus is produced posteriorly into a lanceolate and flat entire or 3-toothed appendage, which is longer than the calyx ! Whether this, taken in connection with the separation of the mar- cescent calyx from the base, will serve to characterize a section or subgenus, I am unable to pronounce. In the place of this appendage, C. lutea, Hook., bears a short gland, like some other species.

Geographical Distribution, &o. A genus of several tropical or sub- tropical species, some of which belong to Equinoctial America (Gynan- dropsis proper, R. Br.) and have the petals imbricated in aestivation ; while the others, with the aestivation of the corolla open, as in Reseda, which form the section or genus Gymnogonia, R. Br., are probably all exclusively na- tives of the Old World, as Mr. Brown supposes. G. pentaphylla, therefore, although spontaneous in the Southern United States, as in the West Indies, was most likely introduced by the negroes, "who use it both as a potherb and in medicine," and therefore should not have been included in this work.
Note. Our figure, made from poor dried specimens, erroneously repre- sents the flower-buds as if with closed petals, which is the case with tiie truly indigenous American species only.

Petals hypogynous, nearly equal, somewhat turned to the upper side, obcordate or obovate and emarginate, on slender or filiform claws, im- bricated in aestivation, deciduous. Torus inconspicuous, convex, produced on the upper side into a thickened gland. Stamens 9 to 32 (usually 12 to 24) : filaments filiform or capillary, declined (purple), inserted on the depressed torus, the anterior ones usually shorter : anthers oval, fixed by the base ; the cells opening introrsely by a longitudinal line. Ovary oblong, glandular-viscid, sessile or nearly so, one- celled, with two parietal placentae : style filiform : stigma depressed-capitate. Ovules very numerous, in two series upon each placenta, horizontal, amphitropous.
Capsule silique-shaped, linear-oblong, turgid, nearly terete, sessile or very short-stipitate, two-valved; the reticulated- veiny valves separating from the filiform placentae ; the style deciduous. Seeds numerous, reniform-conduplicate, exal- buminous. Embryo conformed to the seed : cotyledons incumbently incurved upon the ascending radicle.
Herbs annual, viscid-glandular with a heavy odor, leafy ;

Etymology. Name formed of 7toXijj, many, and aviaus, unequal; from the number and inequality of the stamens.
Geographical Distribution, &c. The genuine species of the genus, founded by Rafinesque on Cleome dodecandra, Michx., belong to the warmer parts of North America, of which P. graveolens alone is diffused northward to the Great Lakes. — The species chosen for illustration is the P. trachy- sperma, Torr. <5r Gray, 1. c. ; but the verrucose-rougheued surface of the seeds, from which the name was taken, is not constant, and is sometimes found in P. graveolens ; the flowers, also, vary greatly in size. The species, however, is perfectly distinguished from P. graveolens, by the long style, the more exserted stamens, and the entire absence of a stipe to the ovary and pod. It would appear to accord very well with P. uniglandulosa, ex- cept that the flowers are only one fourth the size of those delineated in the original figure of that species by Cavanilles.

The Violet Family is represented in temperate regions, especially in the northern hemisphere, by the genus Viola alone, or in the New World by one or two other herbaceous plants, with similar irregular flowers. But within the tropics there are several genera of shrubs, or even trees, widely different in aspect from Violets, some of which have perfectly regular flow- ers. In all, the flower is symmetrical and pentamerous throughout, except as to the pistil, which is only tricarpellary, as is shown by the three parie- tal placentae and the 3-valved capsule. The consolidated style, the stipules, the vernation of the leaves (which are involute or rolled up from their edges inward, instead of from the apex downward), the anthers introrsely adnate to the inner face of dilated membranous filaments, and the large embryo, as well as the prevalent irregularity of the flowers, distinguish the Violet Fam- ily from Droseraceae, the order which it most resembles in character.
The spurred or saccate and larger petal is said to be the upper one, and to become the lower by the resupination of the flower ; but we do not find this to be the case in the Violet. In the Pansy, for instance, it is easy in see that the odd petal is anterior, even while the flower-bud is still sessile or nearly so. The aestivation of the corolla is not convolute, as generally de- scribed, hut truly irnbricative.
An active and emetic or purgative principle pervades the Violet Family, and is chiefly contained in the roots. This principle, called violine, nearly resembles emetine in its properties ; and the roots of several species of Ioni- dium are used in place of those of the true Ipecacuanha. Many South

American species are employed medicinally, or as antidotes to the bites of venomous serpents.
Besides the typical genus, we have one or two species of lonidium indi- genous to the southwestern borders of the United States, and in the North the single species of Solea.

Calyx herbaceous, persistent ; the sepals 5, scarcely une- qual, distinct or nearly so, produced below the insertion into a free appendage, imbricated in aestivation, the odd one su- perior. Petals 5, hypogynous, alternate with the sepals, unequal, imbricated (and a little twisted, but not convolute) in aestivation, one of the two upper and usually smaller ones exterior, the lower one interior and larger than the others, saccate or spurred at the base, marcescent or deciduous. Stamens 5, hypogynous on an annular or concave torus, alternate with the petals : proper filaments very short or obsolete ; the connective dilated, membranaceous, and pro- duced above the anther into a wing-like triangular or ovate apical appendage, the five connivent or more or less coherent over the pistil which they inclose ; the two anterior produced from the back into spur-shaped appendages which are receiv- ed into the spur or sac of the anterior petal : anthers adnate to the inner face of the broad connective, two-celled ; the cells divergent at the base, opening by a longitudinal in- trorse line. Ovary sessile, ovoid-three-sided, one-celled with three strictly parietal placenta? : style terminal, clavate or subulate, various in form, persistent : stigma various, often 13

turned to one side. Ovules numerous, horizontal, in two or more series upon each placenta, anatropous.
Capsule crustaceous or chartaceous, one-celled, many- seeded, three-valved, loculicidal ; the valves bearing the nerviform placenta? on their middle, conduplicate as they dry, so as to project the seeds elastically when they close. Seeds globular or obovoid, indefinite, with a smooth crusta- ceous testa, marked with a distinct raphe and an orbicular impressed chalaza, often carunculate at the hilum. Albu- men fleshy. Embryo straight, in the axis and occupying almost the whole length of the albumen : radicle cylindri- cal, next the hilum : cotyledons oval, flat, parallel with the raphe, foliaceous in germination.
Herbs either caulescent with annual roots or perennial rootstocks, or acaulescent from scaly-toothed rootstocks ; the leaves petioled, involute in vernation, alternate ; the stipules foliaceous, persistent. Peduncles or scapes axillary and solitary, bibracteolate, incurved at the apex, one-flower- ed. Many produce apetalous or cryptopetalous and fertile radical flowers durinsr the summer.
Etymology. The ancient Latin name of the Violet, of obscure origin.
Geographical Distribution, &c. A large genus, belonging chiefly to temperate regions, and principally to the northern hemisphere. There are over twenty species indigenous to the United States proper.
Properties as in the order generally. Some are highly prized for their beauty or their unequalled fragrance.

Calyx of 5 linear and equal sepals, spreading, not pro- duced at the base, nearly as long as the corolla, persistent. Petals hypogynous, nearly equal in length, erect, with their tips barely spreading ; imbricated (as in Viola) in aestivation, marcescent ; the upper and lateral ones alike, narrowly ob- long, emarginate ; the lower one much larger, saccate at the base, dilated upwards, obcordate or emarginate-two-lobed at the apex. Stamens 5, perfectly syngenesious ; the fila- ments proper nearly none ; the connectives membranaceous and dilated as in Viola, but firmly and permanently united by their edges into a sheath (their tips alone becoming free) which incloses the pistil, and bears a single rounded or two- lobed gland on the anterior side next the base^ anthers ad- nate to the inner face, two-celled ; the cells contiguous and parallel, opening introrsely by a longitudinal line. Ovary, &c, as in Viola, but with only 3 or 4 ovules on each pla- centa : style clavate, gibbous and hooked at the apex, the terminal stigma turned to the lower side, simple, perforate.

Seeds large, obovoid-globose, horizontal, conspicuously carunculate at the hilum, anatropous ; the crustaceous testa smooth, marked with a distinct raphe and a large orbicular chalaza. Albumen fleshy. Embryo straight, in the axis and nearly the length of the albumen : radicle next the hilum, very short : cotyledons almost orbicular, subcordate, flat and thin, occupying nearly the whole breadth of the albumen.
Herb pubescent, with a perennial root, and elongated leafy stems ; the leaves alternate, oblong, conspicuously acuminate at both ends, entire, short-petioled ; the stipules linear-subulate, deciduous. Peduncles axillary, short, re- curved, one-flowered, usually two or three from the same axils, ebracteolate, articulated near the middle. Flower small, greenish-white.
Etymology. Dedicated to W. Sole, a German botanist.

Geographical Distribution. Chiefly intertropical both in the New and the Old World. In this country one or two species are found as far north as Texas and Arkansas.
Properties. The roots of numerous species are used medicinally and highly valued in South America, chiefly as emetics. They are known in commerce under the name of While Ipecacuanha; and possess the same properties as the real Ipecacuanha, which they are likewise said closely to resemble in the chemical constitution of their active principles. The roots of our own species doubtless possess the same properties, and might be turn- ed to important account.

The Sundew Family is most nearly related to Violaceae on the one hand and to Cistaceae on the other ; from both of which it is distinguished by its minute embryo, extrorse anthers, the usually distinct or divided styles, the circinate vernation (the inflorescence as well as the leaves being rolled up from the apex towards the base in the bud), and a peculiar habit. The leaves in most plants of the order are beset with stalked glands, which se- crete a clear, viscid fluid, and give the plant the appearance of being cover- ed with dew-drops ; whence the popular name of Sundew, as well as the scientific name of Drosera. Some of the bristly hairs of the common Sun- dew are irritable to the touch ; and this is more strikingly the ease in a New Holland species, in which the glandular fringes of the leaves are said to close upon flies and other insects that happen to alight upon them. This peculiarity is carried to its maximum in Dionsea, the Venus's Fy-trap, of North Carolina, in which the blade of the leaf closes suddenly, so as to im- prison insects which attempt to traverse its upper surface.
The family comprises seven genera, namely, Drosera, which is cosmop- olite and embraces much the larger part of the species ; Sondera, a New Holland genus recently established by Dr. Lehmann, which is remarkable for its octamerous flowers ; and Drosop/ii/llum of the sands of Portugal, Aldrovanda, a floating aquatic of the Soutli of Europe, Roridula of the Cape of Good Hope, Bybhs of New Holland, and Diontca of the savannas of l !arolina, — each of a single species.
192 DROSERACE.E
Little is known of their sensible qualities. The Sundews are somewhat acrid or acid and hitter, and have the reputation of being poisonous to sheep. They impart a deep purple stain to paper in the herbarium ; and it is thought they may afford a valuable dye.
Parnassia, which has long been dubiously appended to this family, from which it differs by its introrse anthers as well as the exalbuminous seeds, should doubtless, for the present, rather be appended to Hypericaceae, to which Don, and subsequently Lindley, have referred it. The latter, indeed, has inserted a proviso, that if " the seeds of Parnassia were really parietal, as they are described to be, that would be a reason for removing it to some other place," * — and he proceeds to maintain that the placenta? in this case and in Hypericum are truly axih ! But how the placentation differs from that of Cistaceae and Violaceae, which are allowed to have truly parietal pla- centae, we are not informed.

Calyx herbaceous, of 5 sepals more or less united at the base, quincuncially imbricated in aestivation, persistent. Pe- tals 5, hypogynous, obovate or cuneiform, convolute-imbri- cated or entirely convolute in aestivation (imbricated, Endl., etc.), marcescent-persistent. Stamens 5, hypogynous, alter- nate with the petals : filaments filiform or subulate, per- sistent : anthers extrorse, immovable, two-celled ; the cells often somewhat separated, opening externally by a longitu- dinal line : poLLEN-grains united in fours. Ovary globular, one-celled : styles 3 or 5, alternate with as many parietal placentae, simple, penicillate-multifid, or more commonly two-parted, with linear or clavate divisions stigmatose on the inner side. Ovules numerous, in two or more series occupying the whole length of the parietal placentae, hori- zontal, anatropous.

ceous and rough or pitted testa conformed to the, nucleus. Embryo very short or minute next the hilum, immersed in or at the extremity of the fleshy albumen.
Herbs growing in bogs, generally of a reddish tinge, the foliage beset with viscid stalked glands ; acaulescent and scapigerous, with the leaves rosulate from fibrous roots or a slender rhizoma, or caulescent (often from a bulb) with al- ternate leaves and terminal peduncles ; the racemiform and unilateral inflorescence and the leaves coiled or rolled up from the apex to the base, in the manner of Ferns. Flow- ers white, purple, or rose-color, expanding successively only in sunshine and for a single day. Stipules usually obsolete or reduced to bristles. Bracts commonly obsolete or decid- uous.
Etymology. Name from Spocrepos, dewy ; the glands exuding a clear fluid, which, in the morning sun, gives the plant the appearance of being covered with dew-drops.
Geographical Distribution. The Sundews inhabit bogs or wet sands in both temperate zones ; but are far more numerous in New Holland. Those of the northern hemisphere are all acaulescent, with naked scapes.
Note. The scorpioid inflorescence is not a true raceme, but a reduced unilateral cyme, as in Sedum ; the pedicels not arising from the axil of the bracts (as is incorrectly delineated in our figure), but laterally, or from the opposite side. Hence the inflorescence sometimes forks, bearing the pri- mary terminal flower in the bifurcation.

Calyx herbaceous, of 5 oblong-ovate sepals, quincuncially imbricated in aestivation, persistent and rerlexed in fruit. Petals 5, hypogynous on the margin of the dilated recepta- cle, alternate with the sepals, spreading, obovate-cuneiform, emarginate or truncate and somewhat erose at the extremity, veiny, marcescent-persistent. Stamens (10 to 20?) com- monly 15, hypogynous within the petals, shorter than they : filaments filiform, monadelphous at the very base, persist- ent : anthers oblong, of two parallel cells without a mani- fest connective, extrorse, attached to the filament by a point above the base ; the cells opening longitudinally and somewhat extrorsely. Pollen of pretty large grains (about the »,',-, of an inch in diameter) composed of four united. Ovary depressed-ovoid, sessile by a broad base, one-celled, five-lobed, the lobes alternate with the petals : style colum- nar, pretty large, undivided : stigmas 5, corresponding witli

the lobes of the ovary, short, erect or connivent, fimbriately many-cleft. Ovules indefinite, anatropous, erect, sessile on and uniformly covering the nearly flat basilar placenta which occupies the whole bottom of the cell.
Capsule membranaceous, utricular, broadly ovoid, ruptur- ing irregularly, or more or less distinctly five-valved, soon decaying or falling away, all but the disk-like base, which is thickened and persistent, forming a kind of border around the flat and circular basilar placenta. Seeds indefinite, ob- ovoid, smooth and shining (black), erect, uniformly covering the placenta or whole bottom of the capsule ; their base immersed in the fleshy scrobiculae of the placenta ; the crus- taceous testa conformed to the nucleus ; the raphe salient : inner integument fleshy. Embryo minute, occupying the base of the fleshy albumen, conical ; the short radicle infe- rior : cotyledons very thick.
Herb acaulescent, very smooth, with fibrous roots, and a rosulate cluster of spreading yellowish-green leaves, which consist of a spatulate-obovate foliaceous portion (the dilated petiole) traversed by a strong midrib, and bearing at its apex an orbicular herbaceo-coriaceous lamina which is emarginate at both ends, fringed with a row of strong spinulose bristles round the margin, traversed by the strong midrib, the two sides conduplicate and the whole incurved on the petiole in vernation ; the upper surface dotted with minute reddish glands, and bearing two or three slender bristles on each side of the midrib, in which the sensitiveness of the leaf chiefly resides ; but which at length fall away from the old leaves. The lobes or sides of the lamina are infolded at night, in re- pose, but spread open in the day ; when if the midrib, or especially the bristles of the upper surface, be roughly touch- ed, or an insect alights there, the sides suddenly close with considerable force and imprison the intruder, the marginal fringes interlacing, like the fingers of the two hands clasped together, or like the teeth of a steel trap. After contraction the trap remains closed for a short time and then slowly expands, ready to close again if newly irritated. But if it be caused to make repeated efforts at short intervals, its
DROSERACE.E. 197
movements become languid, or the sensibility is altogether exhausted, to be recovered only by a period of repose. The scape, which is produced in April or May, is naked, simple, or forked at the summit, bearing a small and umbel-like cyme of pretty large greenish-white flowers. Bracts opposite, or the lower scattered. Stipules none. (The foliage stains pa- per with a brown -purple hue, much as does that of Drosera.)
Etymology. Name from Aiuivrj, the mother of Venus.
Geographical Distribution, &c. This truly wonderful plant abounds in the savannas around Wilmington, North Carolina, and extends north- ward as far as Newbern, and along the Cape Fear River nearly to Fayette- ville. I extract, from an account published several years ago by my friend the Rev. Mr. Curtis, who was long familiar with the plant in its native hab- itat, the following particulars.
" Elliott says, on the authority of General Pinckney, that it grows along the lower branches of the Santee in South Carolina. Dr. Bachman has received it from Georgetown, South Carolina ; and Mr. Audubon informed me, with the plant before us, that he has seen it in Florida, of enormous size [?]. I think it not improbable, therefore, that it inhabits the savannas, more or less abundantly, from the latter place to Newbern. It is found in great abundance for many miles around Wilmington, in every direction. I ven- ture a short notice of this interesting plant, as I am not aware that any pop- ular description of it has been published in this country. The leaf, which is the only curious part, springs from the root, spreading upon the ground, or at a little elevation above it. It is composed of a petiole or stem with broad margins, like the leaf of the orange-tree, two to four inches long, which at the end suddenly expands into a thick and somewhat rigid leaf, the two sides of which are semicircular, about two thirds of an inch across, and fringed around their edges with somewhat rigid cilia; or long hairs like eye- lashes. It is very aptly compared to two upper eyelids joined at their bases. Each side of the leaf is a little concave on the inner side, where are placed three delicate, hairlike organs, in such an order, that an insect can hardly traverse it without interfering with one of them, when the two sides sudden- ly collapse and inclose the prey with a force surpassing an insect"s efforts to escape. The fringe or hairs of the opposite sides of the leaf interlace, like the fingers of the two hands clasped together. The sensitiveness resides only in these hairlike processes on the inside, as the leaf may be touched or pressed in any other part without sensible effects. The little prisoner is not crushed and suddenly destroyed, as is sometimes supposed, for I have often liberated captive flies and spiders, which sped away as fast as fear or joy could hasten them. At other times I have found them enveloped in a fluid of a mucilaginous consistence, which seems to act as a solvent, the in- sects being more or less consumed in it. This circumstance has suggested
198 DROSERACE.E.
the possibility of their being made subservient to the nourishment of the plant, through an apparatus of absorbent vessels in the leaves. But as I have not examined sufficiently to pronounce on the universality of this result, it will require further observation and experiment on the spot to ascertain its nature and importance. It is not to be supposed, however, that such food is necessary to the existence of the plant, but, like compost, may in- crease its growth and vigor. But however obscure and uncertain may be the final purpose of such a singular organization, if it were a problem to con- struct a plant with reference to entrapping insects, I cannot conceive of a form and organization better adapted to secure that end than are found in the Dionsa muscipula. I therefore deem it no credulous inference, that its leaves are constructed for that specific object, whether insects subserve the purpose of nourishment to the plant or not." *

Grass of Parnassus.
Calyx of 5 equal herbaceous sepals, united at the base, and by means of a thickish torus adherent barely to the very base of the sessile ovary, quincuncially imbricated in aesti- vation, persistent, reflexed in fruit. Petals 5, inserted on the torus alternate with the sepals and just within them, quincuncially imbricated in aestivation, ovate or obovate, veiny, widely spreading, tardily deciduous. Staminodia (or sterile stamens of authors) 5, opposite the petals, of which they are probably a deduplication, inserted with them in a series exterior to the true stamens, composed either of a 3 - 5-lobed and glandless dilated-cuneiform scale, or parted into 3 to 13 glandular-tipped setae which resemble abortive sta- mens, persistent, marcescent. Stamens 5, alternate with the petals, inserted just within them : filaments subulate, mar- cescent : anthers cordate-ovate or oblong, introrse (not ex- trorse as usually described), fixed above the base to the point of the filament, two-celled; the cells opening longitu- dinally by an introrse line.

The Rock-rose Family consists of low shrubby plants or herbs, often with viscid branches, with entire leaves, which are either opposite or alter- nate, even upon the same plant, with or without stipules, and with flowers which expand in the sunshine for a single day only, and then (except in Lechea) cast their delicate petals. It is distinguished from all the other hy- pogynous orders with parietal placentation by its orthotropous ovules (except in Fumana) and anisomerous, usually polyandrous flowers. The calyx, which is wholly persistent, should probably be regarded as trimerous rather than pentamerous ; for the two smaller sepals, so called, are entirely exte- rior in the bud, like a pair of bractlets, and not involved in the convolute aestivation of the three inner, or proper sepals. When the petals are only three, they alternate with these last ; but when five, they exhibit no man- ifestly regular order as respects the calyx. They are convolute in aestiva- tion, but turned in the contrary direction from the sepals ; and in the proper Rock-roses the petals are more or less crumpled, as in the Poppy. The stamens are either indefinite, or, when few, very inconstant in number ; and the filaments are never united or collected in clusters as in Hypericaceae. The styles, if any, are perfectly consolidated into one. The placentae, three, five, or rarely ten in number, are either strictly parietal or born>' on partial dissepiments which project into the cell ; and the dehiscence of the 14

capsule being loculicidal, these are borne on tlie middle of the valves, as in the two preceding families. The elongated embryo is more or less excen- tric, and either slightly curved (as in Lechea), or circulate, conduplicate or variously convolute in the midst of the farinaceous (rarely corneous) albu- men ; the slender radicle pointing to the extremity of the seed remote from the hilum.
Cistaceae possess no marked sensible qualities and furnish no useful prod- ucts except a balsamic gum-resin, such as the officinal Ladanum, yielded by Cistus Creticus and its allies, which exudes from the leaves and branches of many species so as to render them glutinous. They are all slightly as- tringent.
The principal home of this family is in the western part of the Old World, and especially around the Mediterranean.
There are five or six species of Helianthemum in the New World, chiefly in the warmer portion of the United States (one of them in California), be- sides Lechea and Hudsonia, which are peculiar to this country.

The St. John's-wort Family is doubtless most nearly related to the tropical order called Guttiferae or Clusiaceae ; but in an extra-tropical Flora it is most conveniently introduced between the Cistaceae and the small family of Elatinaceae.
Among our hypogynous polypetalous orders it is readily distinguished by the opposite and entire leaves, which are punctate (as also the sepals, petals, &c.) with pellucid dots and usually with dark-colored ones intermixed, and destitute of stipules ; by the regular pentamerous (or in Ascyium alone tetramerous) calyx and corolla ; the prevailingly polyandrous and 3 - 5-adel- phous stamens ; the separate or separable styles ; the septicidal capsule ; and the indefinite and exalbuminous (oblong or cylindrical and straight or somewhat curved) anatropous seeds. The embryo is conformed to the cavity of the rather thick and fleshy inner integument of the seed, which some- times has been mistaken for a thin albumen ; it is oblong or cylindrical, with the obtuse radicle usually much longer than the thick or flattish cotyledons. The foliaceous or herbaceous calyx is persistent, and imbricated in sestiva- tion. The petals are either deciduous or marcescent, and usually oblique and convolute in aestivation, but in Elodea they arc equal-sided and quinruu- cially imbricated. The inflorescence is always cymose.
210 • HYPERICACE.E.
The pellucid dots of the leaves are glandular vesicles, filled with an ethe- real oil, of which the coloring matter of the dark glands is probably a sort of resin or balsam. To this secretion, and to the free resinous juice, which especially abounds in tropical plants of the family, the acrid and balsamic qualities which pervade the order are owing. The yellow juice of some Equatorial American trees or shrubs of the order is strongly cathartic, and furnishes a product ( Gummi Gutla) analogous to gaml/oge, which is a prod- uct of some Ceylonese trees of the allied family of Guttiferee.
Hypericacese are widely diffused over the world, but are most abundant in the warmer temperate climes. Far the greater part belong to Hypericum, as received by Linnaeus, Endlicher, and most, botanists. Besides the typical genus, we have in the United States Ascyrum, characterized by its quater- nary calyx and corolla ; and Elodea, with equal-sided petals, and conspicu- ous hypogynous glands interposed between the three stamen-clusters.

Etymology. An old name of the St. JohnVwort, composed of a priva- tive, and a-Kipos, asperity, from the smoothness of these plants.
Geographical Distribution, &c. A genus of several species, natives of the Atlantic and chiefly Southern United States, and of the West Indies. Two species extend northward in the warm Pine barrens near the coast, as far as New Jersey and Long Island. — Besides the genuine species, which have the outer pair of sepals ovate or cordate, many times larger than the narrow or minute and somewhat colored inner pair, and entirely inclos- ing them as well as the pod in fruit, there is a single species in Florida (A. microsepalum, Torr. cj- Gr.; the genus Isophyllum, Spactt) with the small and narrow sepals not more unequal than in Hypericum, from which it dif- fers only in the quaternary number of parts, and to which, rather than to Ascyrum, it should most probably be appended. Thus restricted, the pres- ent genus is well marked in habit and character.

Calyx herbaceous or foliaceous, persistent ; the sepals 5, equal or somewhat unequal, imbricated in aestivation, two of them exterior (and often rather larger), and two interior, distinct, or united at the base. Petals 5, hypogynous, alternate with the sepals, convolute in aestivation, usually oblique or unequal -sided, naked, deciduous or marcescent. Stamens indefinite, very numerous, or sometimes few, hypogynous, commonly 3 — 5-adelphous at the base or more or less distinctly collected in as many clusters : filaments capillary, marcescent : anthers globular, didy- mous, introrse ; the cells opening longitudinally. Hypogy- nous glands none. Ovary of 3 or 5 united carpels (which are opposite the sepals when of equal number), one-celled, with three or five strictly parietal or introflexed placentae, or 3 - 5-celled by the junction and cohesion of the placentae in the axis : styles 3 or 5, filiform, distinct, or united below, sometimes united to the apex, but separable in fruit, persist- ent : stigmas usually capitate. Ovules indefinite, in two or several series on each placenta, horizontal, anatropous.
Capsule like the ovary one-celled with projecting or strictly parietal placentae, or 3 - 5-celled by the junction of the placentae in the axis, septicidally 3 - 5-valved ; the pla- centae adhering to the inflexed edges of the valves, or often

separating from them. Seeds very numerous, anatropous, oblong or cylindrical, straight or sometimes incurved ; the testa usually conformed to the nucleus and crustaceous, or bearing a wing-like raphe ; the inner integument thickish and fleshy. Albumen none. Embryo oblong or cylindrical ; the cotyledons short, at the extremity opposite the hilum.
Herbs or shrubs ; with opposite and entire leaves, punc- tate with pellucid and usually also with dark-colored dots ; and commonly showy yellow flowers, which are terminal and solitary or in cymes.
Etymology. 'YirepiKov, an ancient name, of uncertain derivation.
Geographical Distribution, &c. This large and polymorphous genus is widely distributed over the world, but far most copiously in the eastern part of the warmer temperate regions of the northern hemisphere, bolh in the New and in the Old World. It is doubtless to be divided hereafter, but not to be dismembered to the extent proposed by Spach.
Properties. The herbage is acrid, especially in the herbaceous species, as irt the Common St. John's-wort, which has been variously used in popu- lar medicine. Many species are also balsamic.

The Water-wort Family consists of about twenty known species of annual herbs, usually of small size, growing in water or wet and muddy places. Much the greater number are natives of the Old World, in the northern hemisphere ; the Elatines chiefly in the temperate, and the Bergias in the tropical regions. Of the three known American representatives, two fall within the limits of the present work ; while the third is Brazilian. They are bland plants, destitute of any marked sensible qualities, as far as is known ; although the popular name of Water Pepper in Europe, and the Tamul name meaning Water-fire, which, according to Dr. Wight, is applied to an Indian species, would seem to indicate no small degree of acridity.
Until their separation as a distinct family by Cambessedes, these plants had been appended to Caryophyllacete, on account of a general resemblance to duckweeds ; from which their exalbuminous and anatropous seeds (much more than their capitate stigmas) abundantly distinguish them. Bartling joined them to Lythraces, which some of them resemble in aspect, but from which they differ widely in their stipulate leaves, discrete styles or stigmas, and especially in the hypogynous insertion of the petals and stamens. Lind- ley refers the family to his Rutal alliance, chiefly on considerations deriv- ed from one or two plants which are doubtless with justice excluded from the order. But the nearest affinity of Elatinacea? is evidently on one hand with Hypericacese ; from which they are principally distinguished by their 15
218 ELATINACE.E.
stipules, the absence of pellucid dots in the leaves, and by the perfect sym- metry of the distinct stamens ; and on the other with Crassulaceee, through I)i;imorpha, as has already been suggested by the acute Fenzl.
The two Linnaean genera rested on the number of stamens and styles; Elatine being octandrous and tetragynous, and Bergia, decandrous and pen- tagynous. But it afterwards appeared that the parts of the flower were occasionally ternary, and the stamens sometimes of the same number as the petals only, namely 3, 4, or 5 : and in 1817, Nultall introduced a third ge- nus, Crypta, with a dimerous and diandrous, or rarely trimerous and trian- drous flower, and few seeds. This genus, as well as Bergia, Fischer and Meyer soon afterwards referred to Elatine. In 1829, Cambessedes found- ed on a Brazilian plant a fourth genus, Merimea; which he distinguished from Bergia by its smooth (instead of ribbed) seeds, and strictly septicidal dehiscence, the dissepiments coming aw-ay attached to the valves ; while in Bergia he supposed them to remain adherent to the axis as in Elatine; — leaving the pentamerous instead of 3 - 4-merous flowers to distinguish Bergia from Elatine. The next year, Mr. Arnott, or at least in 1834, in conjunction with Dr. Wight, also referred all the plants of the family (except apparently Lancretia of Delile) to Elatine ; at the same time errone- ously characterizing the dehiscence as loculicidal. Endlicher retained the genera Elatine, Bergia, and Merimea as left by Cambessedes, distinguishing Bergia by the valves of the capsule being introflexed but separating from the persistent dissepiments ; and appending Lancretia to Hypericineae. In 1810, Hooker (in Irones Planlarum) figured a Texan pentamerous species, with just the habit of the Indian Bergias, under the name of Merimea (or Bergia?) Texana ; which, not having ascertained its dehiscence, he referred to Merimea chiefly because of its being a native of the New World. The dehiscence of this species having been ascertained to be septifragal, as in Elatine proper, it was referred to that genus in the Supplement to the Flora of North America, Vol. I. More recently, Fenzl has successfully reduced the whole to the two Linnaean genera ; Elatine comprising all those with septifragal dehiscence, and Bergia (including Lancretia and Merimea) those with septicidal dehiscence ; giving to the former, however, the origi- nal Linnajan species of Bergia. But Seubert has since observed that this species is septicidal, and has restored it to Bergia ; wrongly taking with it, however, our E. Texana, the dehiscence of which, he says, is not clearly de- scribed, although, in the work referred to, it is explicitly said to be septifragal.
As this last plant is now the only pentamerous Elatine, and presents just the aspect of Bergia, I have allowed it to form a distinct section. It should be remarked that the specimens gathered by Lindheimer are decandrous !
Finally, as it appears that our Crypta differs from its allies by the eva- nescent partitions of the delicate pod (if we mistake not), and the basilar placenta, as well as by the few seeds and prevailingly dimerous flowers, I have separated it from the gerontogeous species, as a subgenus merely ; proposing, however, its entire reestablishmcnt, in ease of its corroboration through the New Zealand E. gratioloitks of Cunningham, — a trimerous species of similar habit, which is described as having a unilocular capsule.

The Purslane Family consists of succulent plants, with a watery or mucilaginous juice, entirely destitute of any active or harmful properties, usually bearing ephemeral, and often showy flowers. The order is most allied to the Mesembryanthemacea? on one hand, and to Caryophyllaceae on the other. Its limits are by no means well settled ; but the genuine Portulacaceous plants are recognized by a calyx of two sepals, while the corolla is composed of three to six, usually 5 petals, which have the stamens opposite them or attached to their base, except when the latter are more numerous or indefinite ; and by the commonly one-celled capsule with a free central placenta from the base, with reniform or lenticular seeds having the slender embryo coiled around the outside of farinaceous albumen, as in Ca- rvophyllaceas, &c. Sesuvium anil its allies, however, have a regular 5- parted calyx and are apetalous.
Portulacaeea; are chiefly indigenous to the tropical and warmer temperate regions, and grow in sunny and parched situations, as do other succulents. This is not the case, however, with Claytonia and Montia, which are scarce- ly fleshy, and inhabit rich and damp woods or wet places, and extend north even to the arctic zone.
Several plants of the order besides the well-known Purslane are employed as potherbs. The tuberous root of a Claytonia is eaten in Siberia ; and the farinaceous roots of Lewisia furnish the Indians of Oregon with an important article of food .

Purslane.
Calyx two-cleft or two-parted ; the tube coherent with the lower part of the ovary ; the divisions herbaceous, im- bricated in aestivation, circumscissile round their base and deciduous. Petals 4 to 6, distinct, or a little united at the base, inserted on the summit of the tube of the calyx just where it becomes free from the ovary, equal or unequal, imbricated in aestivation, expanding only once, then colli- quescent. Stamens 8 or numerous, inserted at the base of the petals : filaments subulate or filiform : anthers introrse, didymous, the oval cells opening longitudinally. Ovary ovoid, one-celled, wiflk a free basilar placenta : styles 3 to 8, united at the base, stigmatose down the inner side. Ovules indefinite, erect on capillary and free or branching funiculi from the basilar placenta, amphitropous.
Capsule (pyxis) membranaceous, one-celled, ovoid or globular, circumscissile near the middle at the point where the calyx ceases to be adherent, the upper part falling off as a lid. Seeds numerous, campylotropous, reniform-annular ; the crustaceous and shining testa often granulated. Embryo completely or incompletely annular around the outside of the farinaceous albumen : radicle inferior : cotyledons semiterete, incumbent.
228 PORTULACACE.E.
Herbs low and succulent ; with alternate or irregularly opposite entire leaves, which are either terete or plane, and often furnished with tufts of bristles in their axils ; the up- permost usually involucrate around the solitary or clustered (sessile or pedicellate) flowers. Petals yellow, purple, or rose-color, delicate, expanding in direct sunshine during the forenoon, soon closing, and before evening colliquescent.
Etymology, Geographical Distribution, &c. The old Latin name, of uncertain meaning, for the Common Purslane, which has been used from all antiquity as a potherb, and in salads. All are natives of the tropics and of the southern border of the northern temperate zone ; but the common Purslane has from early times been naturalized around gardens almost every- where. Several showy species have recently become common in cultiva- tion. P. pilosa is indigenous on our Southern frontiers ; and P. oleracea itself is said to be truly wild in Arkansas and Texas.

Calyx deeply five-cleft or five-parted, free, persistent ; the sepals quincuncially imbricated in asstivation, herbaceous, colored (purplish) inside, sometimes mucronate or comute below the tip. Petals wanting. Stamens inserted on the short tube of the calyx, rarely 5 and alternate with the se- pals, oftener 10 to 15, or indefinite : filaments filiform : anthers globular, didymous, introrse, the cells opening lon- gitudinally. Ovary free from the calyx, 3 - 5-celled, with the placenta? in the axis: styles 3 to 5, distinct, stigmatose for the whole length of the inner side. Ovules numerous in each cell, ascending on filiform funiculi arising from the axile placenta.
Capsule (pyxis) ellipsoid or oblong, membranaceous, 3- 5-celled, many-seeded, circumscissile as in Portulaca at or below the middle, the upper part falling off as a lid. Seeds reniform or globular, campylotropous, smooth. Embryo curved around the outside of the farinaceous albumen, an- nular or nearly so.
Herbs prostrate, succulent and maritime ; with opposite and entire fleshy leaves, and terminal or axillary and sessile or short-peduncled flowers.
230 PORTULACACK.E.
Etymology. An unexplained name.
Geographical Distribution, &c. A genus evidently allied to Portu- laca, notwithstanding the 5-sepalous calyx, &c, composed of a few spe- cies of strictly maritime plants, which arc principally tropical ; but two or more species inhabit the coast of the Southern States, and even extend northward, it is said, as far as New Jersey. The species figured is re- markable for having the minimum number of stamens.
