PREFACE.
A pxsrre to advance the science of Botany by any additional remarks and facts which might be in my pos; session, connected with an endeavour to instruct the — ignorant, in this engaging science, are the motives which have induced the author to the prosecution of a laborious but gratifying task.
How much he has drawn from every popular source of information and thus advanced the merit of this little - publication by the labours of others almost every page — can testify. se es
The tacit evidence of Botanists to the accuracy of the prevailing definitions of genera and species, afford, ‘as it were, an almost inviolable sanction to the Ta. bours of their authors, and appear to stamp with te- :
nera, however, since the times of Linnzus, reverting in- a measure to their former simplicity, have now been greatly reduced, and more particularly so, since Botany, assuming a philosophical character, lays chaim to a classification by natural affinities. In this interesting
and now prevailing view of the subject, a reduction of
jections urged against these improvements isthe confu-
heterogenous materials to their natural types, bas led the way to the construction of genera better paces. with the plan of nature. 5
‘One of the strongest, and perhaps most ‘omponile ob
sion which they are innocently the means of introducing,

PREFACE, pa
A considerable portion of new matter is also intro-. duced, which ought perhaps rather to have been ad- dressed to the world through the medium of the uni- versal language of natural science, yet in conformity to the principal intention of the work, and in compliance with the public to whom it is addressed, an uniform language appeared necessary. ;
It will readily be perceived that a Synopsis of the Ge- nera is what is chiefly intended by the present pubes: tion. And to assist the student more fully in the know- ee iedge of genera, the essential character has sometimes. ‘ been extended, after the manner of the celebrated Sprengel’s recent Introduction to the Study of Botany.
I have also considered it of importance to give asketch © _of the habit or mode of vegetation assumed by the
“generic group in imitation of Jussieu’s Genera Planta- s rum, from which important assistance on this sub has been perpetually derived throughout the work.
A view of the Geographical distribution of each ge- nus is also added, not always perhaps sufficiently accu- rate for the existing state of the science, and the “aie : progress of modern discovery,
A brief Catalogue of the species is offered, whic
may.be considered as supplementary to the recent and <extetidive Flora of North America by Frederick Pursh. © Occasional remarksare added, and hew species also pro- | posed and introduced, the result of personal collections and observations made from the year 1809 to the pre- sent time, throughout most of the states and territories _ egperining the Union. oe

Anxious to restrain the limits of this publication
within the bounds of a portable manual for the student, |
and to confine myself as much as possible within the sphere of actual observation, the lower orders of Cryp- togamia, now becoming a partial and particular study, have been omitted, and the rather as they have been Minutely attended to by Z. Collins, Esq. and the late Dr. Mublenberg in his Flora Lancastriensis, which will shortly be published.

With all that has been done in arrang- ‘ing the Scitaminee by the celebrated Mr. Roscoe, there still appears to prevail some confusion in this order, which perhaps their various individual structure has been a prineipal means of retaining. The present plant exbibits several anomalies, considered as a genuine species of Thalia. Jussieu and Persoon, describe the Thalia of Lin-— neus as having a deeply divided petaloid calix, or 5-pe- talied corolla. The T. dealbata, and theT’.. canneformis, 2 of the 3 known species, have a 6-parted petaloid calix. Jussieu also describes this genus as-producing a drupe with a 2-seeded nut, or rarely (by abortion?) 1-seeded. Persoon likewise speaks of this genus as having a drupe with a 1-celled nut. Mr. Roscoe describes the Thalia with a 2-celled capsule; according to Mr. Elliott? the present species produces a globose i-ceiled capsule? or flexible - Shelled hut, if such a phrase can be admitted.

Herbaceous plants with opposite leaves, and generally solitary, axillary flowers, gieatly resembling the preceding genus, to which it is very closely allied; though well dis- tinguished by having 2 of the flaments bifid and for the most part sterile;except perhaps in the L. Pywidaria, the Linnean type of the genus, which is described as haying the 2 inferior filaments terminated by a tooth or pggcess passing beyond the anther which is almost lat serted (or, more probably situated upon anothe eI stipe.) The Lindernia is also distinguished from the pueeed- ing genus by its parallel dissepiment. There is m@eed already a L. dianthera, discovered by Swartz in the West Indies; and Mr. Elliott remarks that there are only 2 an- thers in the ZL. dilatata and L. attenuata of Mublen- _ burgh’s Catalogue, and that in the latter species the infer- tile filaments are villous. Besides these, there is another — species; viz. the L. monticolq of the hills of New Hamp- shire.

The upper lip large, - rounded, and obscurely 3-lobed, the lower lip smaller, about the length of the spur, which is said to be subulate {or as some would perhaps say conic) and emarginate. From all which we may, I think, here perceive a plant not very widely distinct from the U. vulgaris of Pursh and others, considered as equally indigenous, like many other aquatics, to the two continents of.

Calia superior, petaloid, externally hirsute,
deeply 6-parted, nearly equal, erect, and persis- tent. Stamina erect, a little unequal. Style declining; stigma minutely trifid. Capsule round, 3-celled, few-seeded; (3-6 in each cell.)
Leaves considerably like those ofthe Jris; sheathing, on the stem sessile; flowers paniculate, corymbose, exter- nally pubescent, internally coloured and petalwid, nearly equal, but the style somewhat declined and thus ap- proaching to the genus Wachendorfia. The D. Heritiera of the United States, although a very distinet species from ‘the other 4 described as natives of the Cape of Good Hope, can hardly be eonsidered as constituting a distinct genus: it is true, that the stamens are more nearly equal than in the Cape species, but scarcely so, absolutely, with the presence of a declining style. As to the structure of the flowers, they are both merely furnished with a peta-
~ doid calyx, divided down to its base; the Cape species, at
least one examined by Jussieu, had a hirsute capsule, crowned by the persistent calyx, of 3-céils, 3:valves, 3- Seeds, the valves naked in the inside, or without a; recep- ticular placenta, with a central 3-sided receptacle, the seeds flat, and peltate.

The genus Cyperus appears to be widely dispersed over the world, no countries, however, are sorich in this genus asthe United States, the West India islands, and the continent of India; there are also 9 species in Barbary, mest of them common to Europe. The C. favescens, C. virens and the C. fuseus, are the only species in the north of Europe; of which, the first is also common to the Unit- ed States. Northern Asia and Australia appear to afford no species of this genus, though there are many species at the Cape of Good Hope. Upon the whole, it appears that the principal habitat of the Cyperus is North America and India within the tropics. A considerable number of species are common to very distant regions.

‘ \ | Of these, besides what wehave enumerated, New Holland | - affords 32 new species, according to Mr. Brown, besides several others common to various quarters of the world. In Great Britain it is doubtful if there be a single indige- nous species of this genus, if we except the P. Crus-galli, which may, however, have been introduced from the con- tinent of Europe. Desfontaines describes 8 species in Barbary, of which only 2 are peculiarly indigenous, the P. debile and P. Numidianum, the other 6 are equally common to the South of Europe, but of these there are only 3 which correctly appertain to the present genus. Neafly all the other Panicums are pretty equally divided betwixt India and America within the Northern tropic, particularly the West India islands. In Jamaica there is a shrubby s cies, the P. divaricatum, and in India 2- others, viz. the P. arborescens and the P. curvatum. The P. Milium or Millet, now cultivated in the South of Eu- ~» rope, is also from India. From this view, itis evident that
the genus Panicum, generally speaking, belongs to the
tropical regions; hence we finc this genus to increase
upon us in America, as we proceed through the southern
states, where they are often in such abundance as locally
toexclude almost every other grass; still we find many
species of this genus in the United States, extending to, and some even greatly beyond, the 40th degree of North™

It is still cultivated in Italy and other parts of Europe, and from the vast size of its spike must be very productive. Mr. Elliott remarks, that
in Carolina it sometimes attains the height of 10 feet. Of

Europe, India, the West Indies, Africa, andNew Holland.

Although I have not been able, with Mr. Elliott, to ob- serve a 3-valved calix in this singular grass, there still : appears to be sufficient reason to separate it from any ge- hus which can include the Chloris petrea, and C. mucro- 2 nata. The form and character of the calix, the singular
abortion of the flosculi, in which one side of the spikelet
is neutral, the membranaceous consistence of all the
valves, a large sessile accessory valve or single glumed
__ rudiment applied to the dorsal valve of the only herma-
_ phrodite flower, and the awns all arising from beneath
the summit of the valves, are circumstances combined
which perhaps no other known genus possesses.
It exists only, with many other North American plants,
in the primitive maritime soil, and in depressed situations.
Its glandulous aroma is so powerful as to create pun- _ gency on being masticated.

L Jussieu, is almost €x- actly similar to that of the Hamamelis, but in the flowers there exists a strange disparity; by the intervention of thre Pachysandra, however, which appears more properly re- ferable to the Amentacee, than the Euphorbiacee, and at the same time allied both to Hamamelis and Fothergilla, — ; we have something lke a connected series. 1n these 3 ; genera, the anthers and filaments are united, the anthers also become papyraceous, and are for a considerable. length of time persistent, not deciduaus as in the Berbe- rides. ¥rom the Amentacee, they differ in possessing * i _ perisperm, and the Hamamelis is excluded from the 15th - i _ class of Jussieu by the existence of petals, but this exceP- ‘tion is stareely universal, as the order in question in- cludes Comptonia, described as having 6 petals, at all interior and dissimilar calix. Wherever these 3 contiguous genera may be placed, either asa distinct order, (FoTHERGILLEA) or as a neighbouring section, they cannot but be considered as closely allied to the Amentacee, notwithstanding the singular construction of the anthers in the genus Hamamelis, which is indeed the |
sole character by which it is in any manner allied to the Berberides, the carveous perisperm being equally com-
- mon tothe Evpherbiacee. There is some reason to sus- : pect thar the genus Hamamelisis polygamous. independent . of the mistake of Linnzus in confounding this genuswith =

Species. 1. D. stramonium. Overrunning wastes and gardens from the coast of the Atlantic to the sources of the Missouri; but originating probably in South America,
_or in Asia, it is now also naturalized throughout Europe.
Parkinson in his Paradisius, p. 362, says, that the Datu- ras (including the present species) were brought from
» Turkey and’ Egypt, and that Garcias and Christopher
ee Acosta with others, affirmed that they grew in the East Indies. From Boerhaave, the physician and botanist, we also learn that the Datura Stramonium is indigenous to the East Indies, and calied Datura in the vernacular lan- guage of the country, he also adds, that acquainted with its narcotic properties, the natives sometimes employed it as a poison, &c. the same account in part has been re- fently corroborated by the testimony of Colonel Hard- _ wicke, an interesting botanical traveller. Has then the Datura Stramonium been introduced into America from India, and by what means? * | oe 2 Ee Of Datura Persoon enumerates 7 species, forming a- distinct genus of the D. arborea under the name of Brug- mansia; of these 7, 1 is indigenous to China, 1 to Egypt, the fatid D. Metelto Asia, Africa and the Canary islands, the D. levis to Abyssinia, and the D. ceratacayvla to the. isle of Cuba, the real habitat of the D. iaiula and the D. Straménium, can now no longer be ascertained. :
The D. Stramonium, lately introduced into medical _
practice, appears to operate specifically upon the optic ‘nerve when taken-in any considerable quanti y, producing — a remarkable dilatation of the pupil of the eye, anc whea taken inadvertently in dangerous Sepiter, it has been

Near the confluence of Pid- * geon river with the Tennessee, and in some other parts of the state of Tennessee, I am assured by the earliest settlers, that Tobacco came up spontaneous around the : _ ruins of the ancient aboriginal stations. The genuine ha- — ~~ bitat of the Wicotiana Tabacum, though so confidently re- ferred to America, still appears to be involved in obscu-
_ rity; in Europe it was first made known about the year _ 1560 by Nicot, a French ambassador, who had received seeds of it from Florida during his residence at Lisbon, nd it was in honour of him that the genus acquired its name; about the same time also the Spaniards received it _ from Tobaco, a province of Yucatan, hence its common 5; name. ‘The learned Savary, however, asserts that the Persians have cultivated Tobacco (now) more than 400 —-s-years, and that they received it from Egypt. 2. rustica, -...

It is doubtful whether all the benefits which have ac- crued to Europe from the discovery of America, have not been counterbalanced by the introduction of this univers sal luxury, produced at the expense of human liberty, and of a soil which could otherwise be employed in augmente ing the necessaries of life, independent of the diseases in- separable from the use of so powerful a narcotic.

It is probable that hybrids betwixt the European vine,
(Vitis vinifera) and those of the United States would bet- - .ter answer the variable climates of North America than the unacclimated vine of Europe. When a portion of the same industry shall have been bestowed upon the cultiva- tion of the native vines of America, as that which has for so Many ages and by so many nations been devoted to the amelioration of the Vitis vinifera, wecan then no : imagine the citizens of the United States indebted to Eu- rope for the luxury of wine. It is not, however, inthe wilds of uncultivated nature that we are to obtain vines worthy of cultivation, were this the case Europe would to the present have known no other Malus than the worth- — less and austere crab in place of the finest apple,noether = Pyrus‘than the acerb and inedible Pyraster or stone pear, — from which cultivation has obtained all the other varieties.
it is from seed that new and valuable varieties are invari-
ably to be obtained. ‘There is, however, at the present
time, a variety of one of the native species cultivated under
the name of ‘ Bland’s grape,’ an hybrid? no Way, in my
opinion, inferior to some of the best European grapes.

long cultivated it ina garden, it far exceeds in producing,

The V. papilionacea, and V.asarifolia of Pursh, are probably ambiguous varieties of V. cuczllata and V. pal- mata. Whether V. claydestina of the same author be really a distinct species is also equally uncertain, it appears to me nothing more than a smoother variety of V. villosa, if the petals of this plant were indeed “chocolate brown,” that alone would be a sufficient character, but such ano- malies are scarcely to be expected. ;

Pursh’s V. clandestinu. In this species, so accurately de- scribed by Michaux, the leaves are unusually thick, larges and round, constantly appressed to the ground, with a pubescent petiole, and the sinus more closed than in any other species; the flowers, which are of a pale yellow, appear before the complete expansion of the leaves, upon ‘short peduncles; the segments of the calix are oblong; obtuse; the 2 lateral petals are a little bearded and striate; striz, 3 upon each, the uppermost interrupted by the line of pubescence; the lowest petal is uncommonly small, and also striate, the striz bifid and crossed by 2 yellow callous converging lines near the base; nectary almost obliterated; style short and thick, capitulum of the stig- ma small and smoot!:, recurved at the apex, but without rostrum.

The genus Cynanchum appertains principally to the warmer regions of America, a smaller number to India and Africa, 2 to the south of Europe, exclusive of Vince- toxicum so closely allied to this genus; and 1 species even extends to Siberia. Cynanchum is not altogether desti- tute of medical economy; the root of C. Jpecacuanha of Ceylon and the isle of France is used as an emetic in doses of 24 grains, and it has recently been discovered in France that the Senna of the shops was in reality the leaves of a species of Cynanchum disguised by an useless admixture of those of the Cassia Senna.

Umbell rather small, with elongated rays. Um- bellets roundish, with sessile abortive flowers, involucell many-leaved, filiform-subulate. Calix distinct, 5-toothed. Petals cordately-inflected. Styles very short, peltately dilated at the base. Fruit smooth, flat, and subelliptic.—
. Nearly allied to the preceding species, and probably to
E. peucedanifolia of Europe. Hau. On the marshy banks
of the Delaware, near Philadelphia. My friend Z. Col-
‘ lins, Esq. informs me, that this plant attains the height of
6to 10 teet in the marshes of New Jersey, and that the
= lower leaves are extremely long and furnished with nu-
_ (merous leaflets, uniformly narrow like those of the Dela-
eS wate plant.—These 2 — do not well accord ‘with the
+ genus, and appear allied somewhat to Peucedanum, by
_ the flatness of the seeds. Iam satisfied that the celebrated
Sprengel could not possibly have referred our G. rigidiua
to his genus Sivm; one of us must be in an error as to the identity of the plant.
OF this noxions genus there are about 12 species in Eu- rope, Lin Barbary, 1 in tropical America (Hwanaca acaulis, Cav.) 6 at the Cape of Good Hope. According to Per- soon the tuberous roots of (£. peucedanifolia are eaten by children in some parts of France.

Alsinastrum, as well as the disposition of the capsule, are abviously similar, and the former equally discrepant, ppereats with the character of the Caxyo- _ PHYLLEAS; the essential differences of these 2 genera con- _ sist in the number and disposition of the parts.of fructic _ fication, and the absence or presence of styles; in Crypta _ the petals and stamina are equal in number; in E/atine the stamina are double the number of the petals, but the sta- mina themselyes appear similar, in this genus there are ‘ also 3 or 4 cloven styles sufficiently visible, in Crypta 2 or 3 minute and microscopic points in place of styles an@ stigmas. Tothese distinctions we may add the deficiency j of number in Crypta which would not, however, other- ; wise have proved any thing essential.

The discrepancy consists then pally, in the disunion of the filaments at the base, Qdly, in the absence of valves, and 3dly, in the central and sepa- rate situation of the receptacle. “he importance of the ‘first of these objections is removed by the example of Sa- rethra inseparable from this order, in which there is also a capsule ofa single cell, many species of Hypericum have also separated stamina; the second and third objections ap- pear of considerable importance, and operate also against Uniting Dionea with Drosera, notwithstanding their other affinities and the additional one of a simple style, though deeply and divaricately divided, which we have found in | the genus Drogera.—Vhe limits of this little work will not be of extended discussions; and we shall now merely that these plants, if nut actually incorporated with : he HyPERIcINA, ought to form a proximate order.

Species. 1.C. foridus, Ons. Leaves variable, broad oval, or oval-oblong, acute; villous on the under side; the wood and particularly the root strongly camphorated, so as to be calculated probably to produce that drug as abun- dantly'as Laurus camphora. Flowers at first dark brown,
<a paler, in drying parting entirely with this color nd becoming olive green, agreeably scented, almost like ripe apples, similar to all the other North American spe- cies. Anthers and filaments minutely pubescent, the for-
- mer glanduliferous at the summit, interior filaments with-
> Out anthers, - Seeds brown, Neatly as large as horsebeans, ~ Maked, smooth and shining, about 16 in each utriculus, of
a foundish oblong form, marked with a longitudinal suture
and a central hilum; shell hard and cartilaginous; peris- ‘= perm none, or a small central portion gelatinizing when ' Moistened; radicle descendant; cotyledones convolute,
white and large, of an oleaginous bitter taste. Capsule » turbinate, as large as a small pear, marked with the vesti- es of the calycine laciniz, at length becoming perfectly
ty with the seeds loose, but never opening.
Z. Collins Esq. informs me that by cutting off the termi-
- nal leaf-buds, after the usual season, a sticcession of flow-
_* €?s may be obtained throughout the summer, every leaf-
~ bud so extfacted being constantly succeeded by 2 flow- “ers... For oP vee Z. Collins has beens witness to the
success of this experiment, showing in this genus the ve- ty intimate union which subsists betwixt the leaves and
‘Singularly confluent flowers. From the rarity of fruit in the Calycanthi, even in their native mountains, we may almost assert, that this genus, notwithstanding the consi- milarity of its flowers, is in fact polygamous.
