THE complete edition of the MANUAL OF THE BOTANY OP THE NORTHERN UNITED STATES includes the two great Cryp- togamous Families of Mosses and Liverworts (from p. 607 to p. 704), written by Mr. Sullivant, and illustrated with eight copper- plates, crowded with admirable figures. Important as this part is to the Botanist and the advanced student, it is much too difficult for the beginner, and for common instruction in Botany in schools and academies, which will begin with the Phsenogamous or Flower- ing Plants, and will rarely extend into the Flowerless Plants beyond the Ferns and Club-Mosses. As it adds considerably to the size and expense of the book, the part here mentioned is omitted in this Abridged Impression, which is intended especially for the use of classes, and is afforded by the publishers at a price so reduced as to bring the work within the reach of all students. The six plates which illustrate the Ferns and their allies (and which are numbered from IX to XIV) are also given ; so that this edition is illustrated like the other, so far as it goes, and nothing is omitted which ordinary students will require, at least until they have become expert Botanists. It will be seen by the paging, that the omitted matter immediately precedes and follows the Index. Some additions and corrections are given on the following pages. 1 57724 ADDITIONS AND CORRECTIONS.

THIS work is designed as a compendious Flora of the .Northern portion of the United States, arranged according to the Natural System, for the use of students and of practical botanists. The first edition was hastily prepared to supply a pressing want. Its plan, having been generally approved, has not been altered, although the work has been to a great extent rewritten. Its increased size is mainly owing to the larger geographical area embraced in it, being here extended southward so as to include Virginia and Kentucky, and westward to the Mississippi River. This southern boundary coincides better than any other geographical line with the natural division between the cooler-temperate and the warm- temperate vegetation of the United States; very few characteristically Southern plants occurring north of it, and those only on the low coast of Virginia, in the Dismal Swamp, &c. Our western limit, also, while it includes a considerable prairie vegetation, excludes nearly all the plants peculiar to the great Western woodless plains, which approach our borders in Iowa and Missouri. Our northern boundary, being that of the United States, varies through about five degrees of latitude, and nearly embraces Canada proper on the east and on the west, so that nearly all the plants of Canada East on this side of the St. Lawrence, as well as of the deep peninsula of Canada West, will be found described in this volume. The principal facts respecting the geographical distribution of the plants which compose the flora of our district, will be presented in another place. In this work I endeavor briefly to indicate the district in which each species occurs, or in which it most abounds, in the following manner : 1 . When the principal area of a species is northward rather than south- ward, I generally give first its northern limit, so far as known to me, if within the United States, and then its southern limit if within our boun- daries, or add that it extends southward, meaning thereby that the species Vlll PREFACE. in question occurs in the States south of Virginia or Kentucky. Thus Magnolia glauca, p. 16, a prevailingly Southern species, but which is spar- ingly found as far north as Massachusetts, is recorded as growing " near Cape Ann and New York southward, near the coast"; M. acuminata, "W. New York, Pennsylvania, Ohio, and southward"; &c. While in species of northern range, the southern limits are mentioned ; as, Nuphar Kalmiana, p. 23, " New England, New York, and northward"; Cardamine pratensis, p. 33, " Vermont to Wisconsin, northward," &c. And so of Western plants; e.g. Isopyrum biternatum, p. 11, " Ohio, Kentucky, and westward " ; Psoralea aryophylla, p. 94, " Wisconsin and westward " ; Amorplia canescens, p. 95, " Michigan to Wisconsin, and south westward." 2. Where no habitat or range is mentioned, the species is supposed to be diffused over our whole area, or nearly so, and usually beyond it. 3. When the species is of local or restricted occurrence, so far as known, the special habitat is given ; e. g. Vesicaria Shortii and V. Lescurii, p. 38; Sullivantia Ohionis, p. 144, &c. Except in such cases, the want of space has generally demanded the omission of particular localities, which are so appropriate and so useful both in local Floras and in more detailed works, but for which there is no room in a manual like this. For the same reason, I could not here undertake to specify the range of those species which extend beyond the geographical limits of this work, or beyond the United States. Nevertheless, to facilitate the comparison of our flora with that of Europe, I have appended the mark (Eu.) to those species which are indigenous to both. Foreign plants which have become denizens of the soil are of course enu- merated and described along with the genuine indigenous members of our flora ; but the introduced species are distinguished by the specific name be- ing printed in a different type, namely, in small capitals (e. g. Ranunculus ACEIS, p. 10), while the names of the indigenous species are in full-face letter (e. g. R. repeiis). Moreover, the country from which they were introduced is specified (mostly Europe), as well as the nature of the deni- zenship. That is, following the suggestions of M. Alphonse De Candolle, I have classified our introduced plants as well as I could into two sorts, the thoroughly naturalized, and the adventive ; the first comprising those species which have made themselves perfectly at home in this country, propagating themselves freely by seed beyond the limits of cultivated grounds ; the sec- ond, those which are only locally spontaneous, and perhaps precarious, or which are spontaneous only in cultivated fields, around dwellings, or in manured soil, and which, still dependent upon civilized man, would prob ably soon disappear if he were to abandon the country. (I here rank with the adventive plants those which De Candolle terms plants culti/ated with- out or against man's will.) Accordingly the species naturalized from Europe are indicated, at the close of the paragraph, by the phrase " (Nat. from PREFACE. IX Eu.)": those adventive, or imperfectly naturalized from Europe, by the phrase " (Adv. from Eu.)," &c. Such varieties as are marked and definite enough to require names are distinguished in this edition into two sorts, according to their degree of ap- parent distinctness : — 1 . Those which, I think, can hardly be doubted to be varieties of the species they are referred to, at least by those who hold sound views as to what a species is, have the name printed in small capi- tals; e. g. Nasturtium palustre, var. HISPIDUM, p. 30; Vitis cordifolia, var. RIPARIA, p. 78. 2. Those so peculiar that they have not only for the most part been taken for species, but may still be so regarded by many most excellent botanists ; some of them I may myself so regard hereafter, on further and more critical examination of the apparently connecting forms. The names of these are printed in the same full-face type as those of the indigenous species (e. g. Ranunculus aquatilis, var. divaririit us, p. 7 ; Act83a spicata, var. rubra, and var. alba, p. 14) ; and they usu- ally stand at the head of a separate paragraph. Another important feature of the present edition consists in the plates, fourteen in number, crowded with figures, illustrating the genera of the six Cryptogamous Orders (Mosses, Ferns, &c.) embraced in the work. The eight most elaborate and admirable plates illustrating the Mosses and Liv- erworts are furnished by my generous friend, MR. SULLIVANT, the author of that portion of this work.* The remaining six plates^ devoted to the Ferns and their allies, were drawn from nature, and executed by MR. ISAAC SPRAGUE. MR. SULLIVANT has included in this edition all the species of Musci and Hepaticce known to him as natives of any part of the United States east of the Mississippi, and has sedulously elaborated the whole anew ; not only laying a broad foundation for a knowledge of North American Muscology, but furnishing botanical students with facilities for the study of these two beautiful families of plants such as have never before anywhere been afforded in a book of this kind, f * The illustrations of forty of the genera, as indicated in the Explanation of the Plates at the close of the volume, are entirely original productions of Mr. Sullivant's pencil. Seven of them represent new species, and for most of the others those species were chosen which have before been only imperfectly if at all figured. The rest of the genera were taken from Schim- per, Bischoff, or Hooker, but amended or altered in accordance with the object in view, and the suggestions of an actual examination of the plant, which ras always made. t The reference u Muse. Bor.-Amer.," appended to many new or rare Mosses, is made to an almost complete arranged collection of the Musci and Hepaticce east of the Mississippi, the types in great measure of the present elaboration of these families, all critically studied by Messrs Sullivant and Lesquereux, and published in sets of specimens by the latter. The materials from which these sets have been prepared are chiefly Mr. Lesquereux's own very extensive collections, the result of his numerous jourenys made during the last six or seven years, especially in the southern ranges of the Alleghuny Mountains. To these have been added Mr. Sullivant's ample accumulations, embracing the collections of the lamented X PREFACE. Probably the time is now not far distant when, as the result especially of the labors and investigations of PROF. TWKERMAN upon our Lichenes. of the KEY. DR. CURTIS upon our Fungi, and of PROF. HARVEY upon our Algce, as well as of Messrs. SULLIVANT and LESQUEREUX upon our Mosses, all our Cryptogamia may be in a similar manner presented to the student, in the form of a supplementary volume, separate from that com- prising the Phsenogamous or Flowering Plants. J have omitted from this edition the concise Introduction to Botany, and the Glossary, prefixed to the first; supplying their place with a more extended, familiar, and copiously illustrated elementary work, especially intended for beginners (First Lessons in Botany), and which may, when desired, be bound up with the present volume. Or the student may use the author's Botanical Text-Book for the same purpose. In either of these, all the technical terms employed in this volume are explained and illus- trated. Having prepared this Manual for students rather than for learned botanists, I have throughout endeavored to smooth the beginner's way by discarding many an unnecessary technical word or phrase, and by casting the language somewhat in a vernacular mould, — perhaps at some sacrifice of brevity, but not, I trust, of the precision for which botanical language is distinguished. Botanists may find some reason to complain of the general omission of synonymes ; but it should be considered that all synonymes are useless to the beginner, — whose interests I have particularly kept in view, — while the greater part are needless to the instructed botanist, who has access to more elaborate works in which they are plentifully given. By discarding them, except in case of some original or recent changes in nomenclature, I have been able to avoid abbreviations (excepting those of author's names, and some few customary ones of States, &c.), to give greater fulness to the characters of the species, and especially of the genera, (a point in which I conceive most works of this class are deficient,) and also to add the deriva- tion of the generic names. The Natural Orders are disposed in a series which nearly corresponds, in a general way, with De Candolle's arrangement, beginning with the highest class and ending with the lowest ; and commencing this first and far the largest class (of Dicotyledonous or Exogenous Plants) with those orders in which the flowers are mostly provided with double floral enve- Mr. Oakes in the White Mountains, of Fendler in New Mexico, and of Wright in Texas. The title of the work is " Musci Boreali- American!, sive Specimina Exsiccata Muscorum in Ameri- C8e Rebuspublicis Foederatis detectorum, conjunctis studiis W. S. SULLIVANT et L. LESQUEREUX, 1856." Mr. Sullivant's connection with the work extends no further than to a joint and equal responsibility in the determination of the species. This most extensive and valuable collec- tion ever made of American Mosses, which has cost much labor and expense, and comprises nearly 400 species and marked varieties, is published at & 20 for each set, and will doubtless be eagerly sought after by Bryological students. PREFACE. XI lopes, viz. with both calyx and corolla, and in which the corolla consists of separate petals (the Polypetalous division) ; beginning this series with those orders in which the several organs of the flower are most distinct and separate (hypogynous), and proceeding to those which have the parts most combined among themselves and consolidated with each other (perlgynous and epigynous) ; then follow those with the petals combined into a mono- petalous corolla (the Monopetalous division) ; and, finally, those destitute of a corolla or destitute of all floral envelopes (the Apetalous division). The class of Monocotyledonous or Endogenous Plants opens with orders exhibit- ing one form of simplified flowers, passes to those with the organs most combined and consolidated, then to those most perfect and less combined, and closes with other simplified and reduced forms. The present problem in Botany is to group the numerous Natural Orders in each class into nat- ural alliances. But this has not yet been done in such a manner as to be available to the ordinary student. I do not here attempt, therefore, to group the orders naturally, but let them follow one another in what seems to be on the whole the most natu- ral and practically convenient sequence. And, by means of an Analytical Artificial Key to the Natural Orders* (p. xvii.), I enable the student very readily to refer any of our plants to its proper Family. This Key is entirely remodelled in the present edition, is founded on characters of easy observation, and is so arranged as to provide for all the exceptional instances and variant cases I could think of. I shall be disappointed if the attentive student is not able by it to refer to its proper order any to him unknown plant of the Northern States of which he has flowering speci- mens. Referring to the Order indicated, the student will find its dis- tinctive points, which he has chiefly to consider, brought together and printed in italics in the first sentence of the description. Then, to abridge the labor of further analysis as much as possible, I have given a synopsis of the genera under each order, whenever it com- prises three or more of them, enumerating some of their leading characters, and grouping them under their respective tribes, suborders, &c., as the case may be. I have also taken pains to dispose the species of every ex- tensive genus under sections (§) or subgenera (§ with a name in capitals), subsections ( * ), and subordinate divisions (-«-, ++, &c.) ; and whenever there are two or more species under a division, I have italicized some of the principal distinctions (after the manner of Koch's Flora Germanicd), so that they may at once catch the student's eye. To aid in the pronunciation of the generic and specific names, &c., I * No Linnsean Artificial Arrangement is here given, experience having shown that, as a Key to the Natural Orders or to the genera, it offers no clear advantage on the score of facility over a well-devised Analytical Key : which the learner will find equally certain, and much mere satisfactory in its results. XI] PREFACE. hav« not only marked the accented syllable, but have followed London's mode of indicating what is called the long sound of the vowel by the grave (s), and the short sound by the acute accent-mark ('). In respect to this, my friend, MR. FOLSOM, has obligingly rendered most important assistance throughout the pages of this volume. The imperative necessity of economizing space to the utmost, alone has debarred me from more largely recording my acknowledgments to nu- merous obliging correspondents, in all parts of the country, who have con- tributed to this work, either by notes of corrections, observations, or cata- logues, or by communicating specimens of rare or local plants. In the comparison of our flora with that of Europe, I am greatly indebted to my excellent friend and correspondent, M. GODET of Neuchatel, author of the Flore du Jura, for a suite of authentically determined plants of that district, and for a series of acute and very important critical notes upon many of our own identical or related species. As to special collaborators in the preparation of the work, in addition to the acknowledgments made in the preface to the former edition, I have again to express my particular indebtedness to my friends, JOHN CAREY, ESQ., now of London, for various emendations in the genus Carex, formerly elaborated by him for this work ; and DR. ENGELMANN of St. Louis, for full notes upon the botany of our Western borders, many critical obser- vations upon various genera, and for contributing the articles upon Cus- cuta, Euphorbia, and the three genera of Alismece. The renewed and still more extensive contributions of MR. SULLIVANT have already been referred to, — contributions which introduce a new era in the study of American Muscology, and which justly claim, not only my warm per- sonal acknowledgments, but the gratitude of all the votaries of our science in this country.' I renew the request, that those who use this book will kindly furnish information of all corrections or additions that may appear to be necessary, so that it may be made more accurate and complete in a future edition HARVARD UNIVERSITY, CAMBRIDGE, June 30tft, 1856.

THE Student is supposed to have a general acquaintance with the rudiments of Structural Botany, such as is readily to be acquired from the author's First Lessons in Botany, or his Botanical Text-Book, or from any other similar trea- tise. One of these will be needed for reference while using this Manual. The former is much the simplest, and* was expressly prepared for the beginner's use, To learn the meaning of all words he meets with, and which he does not precise ly understand, he has only to refer, as occasion requires, to the Glossary or Dic- tionary of Botanical Terms appended to either of these books, especially to that in the Lessons on Botany. To show the beginner how to proceed in using the Manual for the purpose of ascertaining the name,' and the place in the system, &c. of any of our wild plants, we will take an example. Suppose him to make his first trial with the common Spidcrwort, which grows wild throughout the southern and western parts of our country, is cultivated in most gardens, and blooms the whole summer long. With a flowering specimen in hand, let the student turn to the following Arti- ficial Key to the Natural Orders, p. xvii. Having flowers, it is evident the plant belongs to the great series of Phcenoyamous or Flowering Plants. To which of its two classes is the first question. To answer this, let the student compare the plant with the characters — that is, the enumeration of the principal distinc- tions— of Class I. given on p. xvii., and of Class II. on p. xxi. Without the seeds, which may not be ripe, — and if they were it might require more skill than could be expected of the beginner to dissect them, — we cannot directly ascertain whether the embryo is monocotyledonous or dicotyledonous. But the other characters are abundantly sufiicient, and easy to verify. Take first the stem ; is it formed on the exogenous or endogenous plan ? A slice across it plainly shows, to the naked eye, or by the aid of a common magnifying-glass, that there is no distinction of parts into pith, bark, and a ring of wood or woody tissue between these two : but the woody part of the. stem is here represented by separate bundles, or threads, whose cut ends, as seen in the cross-section in tho form of dots, are scattered throughout the whole diameter, — just as in a stalk of Indian Corn, a (rattan, or a Palm-stem, — leaving no central pith and showing no tendency to form a ring or layer of wood. It is therefore endogenous. The simple, parallel-veined leaves show the same thing, and so does the arrangement of the flower with its parts in threes, — namely, three sepals, three petals, six (twice 3) stamens ; and even the pistil, if the ovary be cut across, is found to have three cells. So the plant plainly belongs to Class II* Monocotyledonous or Endogenous Plants. We have next to refer it to its proper Order under this Class, which is readily done oy fc llowiiig the successive subdivisions in the Artificial Key. The first XVI DIRECTIONS TO THE UNPRACTISED STUDENT. division is into three groups, marked A. B. and C. Of these B. alone has "flowers with true floral envelopes," and therefore includes our plant. The subdivision of B. is into "1. Flowers densely crowded on a spadix," and "2. Flowers not on a spadix." Our plant falls under the latter. This is subdivided into " * Perianth adherent to the ovary," and " * # Perianth free from the ovary" Our plant accords with the latter. This is subdivided into four groups, with this mark (•«- ), characterized by the nature of the perianth ; and it is evident that our plant, having 3 green sepals, and 3 colored petals, and no glumaceous or husky bracts, falls into the third group, •»-•*-•*-. Under this there are four alterna- tives, based on differences in the pistil. The numerous distinct pistils exclude the first ; the many or several seeds in each cell exclude the second ; the one- celled ovary, &c. exclude the fourth ; while the third, having a single pistil with a 2 -3-celled ovary, and only one or two ovules' or seeds in each cell, agrees with our plant ; which we are thus brought to conclude must belong to the order Comme/ynacece. The number, 485, affixed to this name, refers to the page in the body of the work where this order is characterized. After comparing the plant with the ordinal character, especially with that por- tion of it in italic type, and noting the agreement, let the student proceed to de- termine the Genus. "We have only two genera in this order, viz. : 1 . Commelyna, which lias irregular flowers, petals unlike and on long claws, and the stamens of two sorts, only three of them bearing perfect anthers, — all of which is very different from the plant we are studying; and 2. Tradescantia (p. 486), with the characters of which our plant will be found perfectly to accord. Let the student then proceed to ascertain the Species, of which three are de- scribed under this genus. Of the two sections, marked with stars ( * ), our plant belongs to the first, having a sessile umbel. And of its two species, a comparison with the characters of each fixes our plant as belonging to the first, viz. T. Virginica. The abbreviated name or letter after the name of the genus and that of the species, denotes the founder of the genus or the species ; — in this instance Lin- naeus, whose name is indicated by the abbreviation L. Whenever an order comprises several genera, a synopsis of them is given, like that of Ranunculaceoz, p. 2, by the aid of which the student will readily deter- mine the genus of the plant under examination. The number prefixed to the name of the genus, in the synopsis, is that under which it stands, farther on, in the full account. The genera in the synopsis are often ranked under their proper Tribes, or Suborders, &c. ; and the student will first determine the Tribe, or other great group to which the plant he is examining belongs, and then the Genus under that tribe, &c. Sometimes a genus embraces two or more strongly marked sections, or Sub- genera, which are designated by the mark § followed by a name. For example, Cimicifuga, p. 14, has two subgenera, § 1. Macrotys, and § 2. Cimicifuga proper, each with its own characters ; and the genus Rhus, p. 76, has three subgenera, viz. § 1. Sumac, § 2. Toxicodendron, and § 3. Lobadium. These names, how- ever, do not make a part of the appellation of a plant, which is called by its generic and its specific name only ; as. Cimicifuga racemosa, the Black Snake root ; Rhus ylabra, the Smooth Sumac, &c.

The flowers with a strap- shaped (ligulate) corolla are called rays or ray-Jlowers : the head which presents such flowers, either throughout or at the margin, is radiate. The tubular flowers compose the disk ; and a head which has no ray-flowers is said to be discoid. The leaves of the involucre, of whatever form or tex- ture, are termed scales. The bracts or scales, which often grow on the re- ceptacle among the flowers, are called the chaff: when these are wanting, the receptacle is naked. — The largest order of Phaenogamous plants, divided by the corolla into three suborders, only two of which are repre- sented in the Northern United States. SUBORDER I. TUBULIFLOK^E. Corolla tubular in all the perfect flowers, regularly 5- (rarely 3 - 4-) lobed, ligulate only in the marginal or ray-flowers, which when present are either pistillate only, or neutral (with neither stamens nor pistil). The technical characters of the five tribes of the vast suborder TvIniliflorcR, taken from the styles, require a magnifying-glass to make them out. and will not always be clear to the student. The following artificial analysis, founded upon other and more obvious distinctions, will be useful to the beginner. (The numbers are those of the genera.)

It was afterwards published by his son, under the name of P. Hudsonica : he, however, found it " only on the banks of the Hudson River, above Albany." Lastly, it was described as P. betulifolia by Pursh, who further added as its station, " about Lake Ontario." The tree was probably an introduced form of the European P. nigra, and was latterly so considered by the younger Michaux himself. A few of these trees are still found in the neigh- borhood of Hoboken, New Jersey. P. DILATATA, Ait., the well-known pyramidal LOMBARDT POPLAR, has been extensively introduced as an ornamental tree, and is found in the vicinity of all old settlements. P.

Mr. Tuckerman informs me that he has seen a specimen in a European herbarium, purporting to have been gathered in Delaware. If found, it may be distinguished from No. 8 by its lanceolate and wavy-crisped 3-nerved leaves. P. DENSUS was admitted into the first edition on the authority of Beck from Schweinitz.

Peri- anth of 6 divisions in 2 sets ; the 3 outer (sepals) of the same petal-like texture and appearance as the 3 inner (petals), of which the upper or pos- terior one, but by the twisting of the ovary or stalk commonly appearing the lower or anterior, differs more or less in shape or direction from the others, is often spurred or appendaged, and is called the lip. Opposite this, in the axis of the flower, is the column, which is composed of a single stamen (or in Cypripedium of 2 fertile stamens) entirely coherent and confluent with the style, on which the 2-celled anther is variously situated. — Perennial herbs, often tuber-bearing, or with tuberous or thickened roots.

Cryptogamous plants with a distinct axis (stem and branches), growing from the apex only, containing woody fibre and vessels (especially ducts), and usually with dis- tinct foliage. ORDER 135. EQUISETACEJE. (HORSETAIL FAMILY.) Leafless plants, with rush-like hollow and jointed stems, arising from run- ning rootstocks, terminated by the fructification in the form of a cone or spike, which is composed of shield-shaped stalked scales bearing the spare" cases underneath. — Comprises solely the genus 1. EQUISETUUI, L. HORSETAIL. SCOURING RUSH. (Tab. 14.) Spore-cases (sporangia, thecce) 6 or 7, adhering to the under side of the angled shield-shaped scales of the spike, 1 -celled, opening down the inner side and dis- charging the numerous loose spores. To the base of each spore are attached 4 thread-like and club-shaped elastic filaments (daters), which roll up closely around them when moist, and uncoil when dry. — Stems striate-grooved, rigid, the hard cuticle abounding in silex, hollow, and also with an outer circle of smaller air-cavities corresponding -with the grooves ; the joints closed and solid, each bearing instead of leaves a sheath, which surrounds the base of the inter- node above, and is split into teeth corresponding in number and position with the principal ridges of the stem : the stomata always occupying the principal grooves. Branches, when present, in whorls from the base of the sheath, like the stem, but without the central air-cavity. (The ancient name, from equus, horse, and seta, bristle.) 586 EQUISETACE.E.

(Eu.) ORDER 136. FILICES. (FERNS.) Leafy plants, with the leaves (fronds) usually raised on a stalk or petiole (called the stipe}, rising from a root or mostly from prostrate or subterranean rootstocks, separately rolled up (circinate) in the bud (except in Suborder III.), and bearing, on the veins of their lower surface or along the margins, the simple fructification, which consists of l-cetted spore-cases (sporangia), open- ing in various ways, and discharging the numerous minute spores. (An- theridia and pistillidia formed on the seedling plantlet !) — Comprises three very distinct Suborders, which now are by many received as separate families : — SUBORDER I. POLYPODINEJE. THE TRUE FERNS. Sporangia collected in dots, lines, or variously shaped clusters (sort or fruit-dots') on the back or margins of the frond or its divisions, stalked, cellular-reticulated, the stalk running into a vertical incomplete ring, which by straightening at maturity ruptures the sporangium transversely on the inner side, discharging the spores. Fruit-dots often covered (at least when 588 FILICES. (FERNS.) young) by a membrane called the indusium, growing either from the back or the margin of the frond. (Tab. 9-12.) TRIBE I. POL.YPODIEJE.
