THIS WORK IS RESPECTFULLY INSCRfBED, AS A TRIBUTE OF RESPECT FOR HIS SCIENTIFIC ATTAINMENTS, AND AS A TOKEN OF ESTEEM FOR HIS PERSONAL CHARACTER, BY HIS FRIEND, THt: AUTHOR. PREFACE, JL HE progress of botanical science in the United States has been so rapid during the last few years, that new works, containing the discoveries continually making, are, from time to time, required. The excellent Flora of Mr. Pursh, which appeared in 1814, exhibited all that was then on re- cord, as well as all which the enterprising author himself discovered, relative to North-American botany. Since that lime have appeared the " Genera of North-American Plants," by Mr. Nuttall, a work which has contributed more than any other to advance the accurate knowledge of the plants of this country ; Mr. ElHott's excellent " Sketch of the Bo- tany of Georgia and South-Carolina ;" " Barton^s Flora of North-America," besides numerous monographs and miscel- laneous observations on North-American plants, published in various scientific journals. A considerable number of out- plants have also found their way to Europe, and have there been described and illustrated by the most celebrated botanists of the age. A small proportion, however, of North-American plants, even of those growing in the most explored parts, have yet been attentively examined. Having devoted a number of years to the study of the plants of this country, particularly those of the northern and middle parts of the United States, the author conceived that a Flora embracing this section, would be a proper counter part to the work of Mr. Elliott on the Botany of the Southern States. He accordingly commenced collecting materials for the present- work; and, after much labour and care, he at length ventures to submit it to the public. The ad- vantage of local Floras is now generally acknowledged ; as their authors, it is presumed, must be better acquainted with the plants of which they treat than with those of a more ex- tensive district; they are the means of recording many facts and observations, and minute descriptions, which could not be introduced into general works; they also increase our knowledge of vegetable geography. It has been the object of the author to bring together all that has hitherto been published on the subjects embraced by this work, and to add such observations as his own opportuni- ties have enabled him to make. In prosecuting this task it lias been necessary, in many instances, to alter andanriend the characters of genera and species as they were described in previous works, and also to make some changes in nomenclature. He is well aware of the, great inconvenience of changing established names, but this must necessarily be done while botany is an advancing science. A large pro- portion of our plants have not been examined since botany has assumed a philosophical character : hence they have been imperfectly described, and, in many instances, referred to wrong genera and species. We are, therefore, often under the necessity of using erroneous names, or of changing thena for such as are more appropriate. It appears to us that the interest of science requires us to adopt the latter alternative ; but, at the same time, to make no alteration except such as the natural progress of botany renders necessary. There can be little doubt that Linnceus himself, had he lived to this day, would have materially altered both his system and nomenclature ; as he did in each successive edition of his own works. In all cases where there was not especial reason for the contrary, we have adopted the names given to plants by those who discovered or first described them ; thus we have revived the neglected name of Bartonia, given to a plant by Muhlenberg, and described in 1801, in- stead of adopting Centaurella of JVIichaux, which was several years later ; Gi/mnopogon of P. de Beauvois has been pre- ferred to Anthopngon of Nuttall, and Brasenia of Schreber to Hydropdlis of Michaux. So in specific names, Frasera carolinensis and Utriculnria injlata of Walter, have beea used instead of F. Walteri and U. ctratophylla of Michaux. The most important changes of this kind have been intro- duced in the Gkamine^, a family which has been less attended to by our botanists than any other of the phanerogamia. Mr. Nuttall has exhibited his usual acuteness in reforming their characters, but, as thfe Agrostographia of P. de Beau- vois had not reached this country when he published his valuable work, most of his new genera must give place to those of the French botanist. It is principally to this work, and to the recent Agrostographia of Trinius, that the author is indebted for the improved generic characters of the grasses, as well as for the somewhat new arrangement which he proposes. The Umbellifeu* are adopted with but Httle alteration from Sprengel, as they are elaborated by him in the 6th vo- lume of Roemer & Schultes' Systema Vegetabilium, though his distribution of the North-American species of this tribe is not ahogether satisfactory. Of the Cryptogamia, it is concluded at this time to* de- -scnbe only the ferns, leaving the other orders for a future period; when the author, in connexion with his friends, the Rev. L. D. Schweinitz, and A. Halsey, Esq. proposes to give a Cryptogamic Flora of the United States. Large col- lections have already been made towards this work. The names of genera and species proposed by the author have an asterisk (*) annexed to them. To a few doubtful plants the mark (+) is added. It is probable that these last should all be expunged from our Flora. The detailed descriptions are always original, except in a few cases, where the authority is given. The author would not forget his friends who have assisted him in contributions to this work. Although their names ap- pear so frequently on its pages, he must express his particu- lar obligations to the following gentlemen : — Prof. Bigelow, and J. Oakes, Esq. for plants of the vicinity of Boston, the White Hills, &c. ; Prof. C. Dewey, Dr.' J. Porter, Dr. Cooley, and the Rev. Mr. Hitchcock, from various parts of Massachusetts ; Dj. E. Ives, Dr. J. Hooker, and Mr. J. B. Brace, from Connecticut; Dr. L. C. Beck, Mr. J.Tracy, and Dr. E. James, from Albany and its neighbourhood ; Dr. M. Stevenson, from the northern parts of the State of New- York ; Dr. J. Barratt, from the Highlands; VVm. Cooper, and A. Halsey, Esqrs. from the vicinity of this city and else- where ; and Capt. Le Conte, Mr. A. Eaton, and the Rev. Mr. Schweinitz, from various parts of the northern and middle States. To the Messrs. Prince, of Flushing, he is indebted for unrestrained access to the Linna^an Botanic Garden ; which extensive collection embraces a large pro- portion of the plants of our country, capable of cultivation. Their establishment merits the extensive patronage it re- ceives. As this work, from its size, may be inconvenient for rc« ference in the field, or may be too expensive for many bo- tanists, a Compendium, comprising the essential generic and specific characters of all the plants described in the larger Fiora, has been prepared, and will shortly be published. Should the present undertaking be favourably received by the botanic world, it is the intention of the author to publish a General Flora of North-America, to include all the dis- coveries made since the work of Mr. Pursh, now amounting to many hundred species. Collections are continually making for this purpose, and the aid of botanists in all parts of our country, by the communication of local catalogues, observa- tions, and dried specimens, is respectfully solicited.

MONANDRIA. MONOGYNIA. S years since by Dr. L. C. Beck, a gentleman to whom I am under many obligations for his valuable contributions to this work. From a careful comparison of the American Hififiuris with numerous specimens of H. -vulgaris of Europe, I have little doubt of their identity. The former has, according to the observations of Dr. Beck, pretty constantly eight leaves in each whorl, though Michaux describes it as having six. Pursh remarks {Fl. 11. p. 774) that he compared speci- mens of Hififiuria vulgaris from Hudson's Bay, with the European species, and found them entirely distinct.

I should have adopted his name, had it not been already applied to a South- American genus. This species is said to be also a native of Japan, which seems hardly probable.

This deservedly celebrated botanist, to whom we are so largely in- debted, more particularly for his labours in the Cryptogamia, has given a new description of the genus Lemna in his valuable Flora Scotica, which I shall here quote. " All the species are aquatics, floating on the surface, or sinking only when the seed is ripe, and the plant dying away. Fronds (for I cannot consider the whole plant, from which spring the flowers, as a leaf) mi- nute, ovate or orbicular, compressed, foliaceous, or thick and succulent; from the centre beneath, throwing out one or more slender roots, which are terminated by sheath-like appendages 2 DIANDRIA.

The margins of the fronds at one extremity, on each side, have a cleft, in which some- times are produced one or more flattened orbicular gemmx^ (and this is their common mode of increase,) which there grow into perfect fronds, and then fall away, or a single j?ow(?r, con- sisting of an urceolate, membranaceous, monophyllous peri- anth^ from a small opening in the top of which the stigma is protruded, and which bursts irregularly as the stamens become developed. These are two in number {rarely wanting.) An- thers of two rounded lobes, opening nearly vertically, each into 2 valves.

There has been much confusion respecting the two species of lias here described, the principal cause of which is the im- perfect descriptions given of tliem by L i n nxus and Wi 1 1- denonv. The Iris virginica of Purgh and other botanists is not sufiicienlly distinct from I. versicolor. Our l.' virginica is the true plant of Linn a: us, according to Muhlenberg's Herbarium, which I have lately had an opportunity of examin- ing. _ Pursh quotes the >^-. in Dillen. Hort. Eltham (188.) for his I. virginica, but the plant there represented is certainly only a variety oil. versicolor, to which it is referred by Will- denow.

The flowers of the species of Iris being of such delicate structure that they lose many of their characters in drying, I am unal)le to determine whether the plant above described is distinct from I. cristata of A it on. It does not dilTer from the description in the Hort. Keivensis, except in having, ac- cording to J^fu (tall, flowers destitute of a bearded crest. It appeared to me, however, in the specimens collected by Capt.

Muhlen- b erg., in his Catalogue, has given New-York as a habitat of this plant; but I am assured by Prof. J.

The genus Lachnanthes o^ Elliott is still retained in DiLATRis by JVu ttall. With deference, however, I am obliged to differ from this excellent botanist in this instance. The for- mer appears to have sufficient characters to constitute a dis- tinct genus, namely, its monopetalous corolla, equal filaments, and many-seeded cells.

Pursh, who appears to have first noticed this grass, de- scribes the flowers of the panicle as antheriferous only ; but in all the specimens which I examined I have found them to pro- duce perfect seeds, though smaller than those of the radical flowers. This Milium will probably hereafter be the type of a new genus, as it differs so remarkably from every other known species. 3.

I " The seed of the STMPtocARprs does not appear to possess any thing' like a proper cotyledon ; the embryo formed in the exact posture of the growing- plant (witli the radical downwards) differs not from it in any par- ticular but that of size. In place of a Cotyledon, there is a sheathing sti- pule similar to that which is ever afterward prodcced ; in fact, it is viva,- parous. The embryon is seated in a small umbilical or henaispherical de-- pfession, in the upper end of what may be called a ritellus rather than a perisperm, judging from its functions ; the callus or seminal tubercle is roundish and turbinate, nearly as large as a filbert nut, very solid and car- neous, possessing in a high degree the alliaceous fetor of the grown plant. The mutual point of attachment between this body and the embryon is at first a minute and nearly central funiculus, which' enlarges and becomes more distinct during the process of germination ; but what appears to be most sin.e;ular in it, is the length of time which it continues attached to the growing plant, apparently inert at the base of the casidcs for twdvc or even eighteen montirs."

I strongly suspect this plant is only a variety of V. blanday though tliis opinion is opposed to that of so accurate a Bo- tanist as Mr. S c hw einit z. There is no c'naracter in the above description, which does not apply to V. blanda when it begins to produce apetalous flowers, except the colour of the petals.

The floriferous stolons are not unfrequent in this tribe of the VioiiE, and the short linear petals I have ob- served in several species.

JSTutta 1 1 has constituted a new genus of the North-Ame- rican species of Thesium, principally on account of the anthers being connected to the calyx by a tuft of filaments. This cha- racter exists, more or less, in many of the species of this genus as now characterized hy R. Brown.

The true structure of the fruit of this plant was entirely misunderstood, until it was described by the learned and inge- nious R. Brown. What was supposed to be a drupe by Mic hau X, and all suceeding Botanists, is only a naked seed which had early ruptured its pericarp, the remains of which are easily seen at its base ; the " nux cornea crassissima" is the albumen, and the "seed" is the embryo. 228.

I received specimens of this plant, in fruity about eight years since, from Dr. Ed to in J a m e s, who discovered it at Greenbush, near Albany. Having only seen imper- fect specimens, I was ignorant of the structure of the flowers, but referred it to Monotropa as the genus to which it was most nearly allied, and a short description was published in £ Q t on's Manual of Botany, ed. 2d. 1818, under the name of M. firocera. There can, however, be no doubt of its be- longing to a genus quite distinct from Monotropa. This plant is said, by Mr. M'uttall, to be an evanescent annual, but I am assured by Mr. Tracy^ of Albany, an accurate Botanist, that it is certainly a perennial. He has taken up the roots from their native soil, and transplanted them into his garden, where they flowered. I am informed that the Pterospora has lately been illustrated in Europe by Ho ok er^ and also by Lindley and Drown; but unfortunately their publications have not yet reached this country, so that I am unable to avail myself of their valuable observations. 2G6.

This acute Botanist separated them Py- BOL^, as was long before proposed by Mi c h a u x, on ac-* count of their sessile stigmas, and the anthers being rostrate and opening by a subbivalve foramen. But in their anthers they certainly agree with the other PyROLiE, opening by 2 simple pores at their base ; and in the stigma, they differ from, each other, it being furnished with a short style in P. umbellata^ and quite sessile in P macuiata. Dr. Big e low, in '.is Me- dical Botany, above qnoted, under the article Pyrola umbel- latay has given excellent reasons for I'etaining these species iu the genus where they were originally placed, and has shewn that they diflFer as much from each otlter, as some true Py- rola do from these. t In Air. JVji t f all's improved gene- ric character of Chimaphila, he describes the filaments as sti- pitate, with a ciliate discoid stipe, and the capsule with the valves unconnected by a web. In P. secunda, however, the valves of the capsule are likewise unconnected. It appears to me, therefore, better to restore Pursh's genus to Pyrola. 288. LEDUM. L, \ Calijx minute, 5 -toothed.

The S Portulacastrum, a native of India, and the only Lin- nsean species of the genus, has been divided by De Cando lie into S. fiedunculatum, sessile, and revolutum. The first is com- mon on the sandy sea-coast in the Southern States. Mr. J^u t- ia II is, I believe, the only Botanist who has observed S. ses-^ sile in this country. Mr. Elliott thinks the capsule of Sesuvium has been incorrectly described as cut round near the- base. He remarks that it has towards the summit three su- tures distinctly marked, but the base is membranaceous and vei-y delicate, and appears to decay or tear as the seed becomes mature, suffering the more substantial summit to fall off with- out opening But in some of my specimens there were many ripe causules, which appeared to open transversely all rounds by a wtii defined margin. 321.

S m i t A, to whom I sent specimens for examination, it is totally unlike that species, or any other that he had seen. The nectary or disk on which the stamens are inserted, is a remarkable character in this genus, and is not no- ticed by Lehmann \\\ his recent elaborate Monography ot PoTENTiLLAc On accouut of this peculiarity Dr. Big e lou proposes it as a new genus under the name of Bootia.I 331.
