PREFACE,

Tis 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

viii 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. Jsopyrum biternatum, p. 11, ‘‘ Ohio, Kentucky, and
westward”; Psoralea argophylia, p. 94, “ Wisconsin and westward ” ;
Amorpha canescens, p. 95, “ Michigan to Wisconsin, and southwestward.”
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 pimniadé in a different type, namely, in small capitals (e. g. Ranunculus
ACRIS, p. 10), while the names of the indigenous species are in full-face
letter (e.g. R. repems). 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 cultivated 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 “ (Ady. from Eu.),” &c.

Such varieties as are marked and definite enough to require names are
distinguished i 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. divaricatus,
p- 7; Actzea 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.) deabenndd % in the work. The
eight most elaborate and admirable plates illustrating the Mosses and Liv-
erworts are furnished by my generous friend, Mr. SuLLIv AN, 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. Sutiivanr has included in this edition all the species of Musci
and Hepatice 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.+

* 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 was always made.

t The reference ‘‘ Musc. Bor.-Amer.,” appended to many new or rare Mosses, is made to an
almost complete arranged collection of the Musci and Hepatice 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 haye been prepared are chiefly Mr. Lesquereux’s own
‘Very extensive collections, the result of his numerous journeys made during the last six or
Seven years, especially in the southern ranges of the Alleghany Mountains. To these have
been added Mr. Sullivant’s ample accumulations, embracing the collections of the lamented

PREFACE.

Probably the time is now not far distant when, as the result especially
of the labors and investigations of Pror. TucKERMAN upon our Lichenes,
of the Rev. Dr. Curtis upon our Fungi, and of Pror. Harvey upon
our Alge, 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 Pheenogamous or Flowering Plants.

I 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-Americani, sive Specimina Exsiccata Muscorum in Ameri-
cx Rebuspublicis Foederatis detectorum, conjunctis studiis W. 8. 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,

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 (perigynous
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 Germanica),
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 Linnean 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
4 well-devised Analytical Key; which the learner will find equally certain, and much more
satisfactory in its results.

have not only marked the accented syllable, but have followed Loudon’s
mode of indicating what is called the long sound of the vowel by the
grave (~), and the short sound by the acute accent-mark (’). In respect
to this, my friend, Mr. Foxrsom, 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. Goprr 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, Joun Carey,
Esq., now of London, for various emendations in the genus Carez, formerly
elaborated by him for this work; and Dr. ENGELMANN of St. Louis, for
fall 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 Alismew. The renewed and
still more extensive contributions of Mr. Surtivanr 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.

DIRECTIONS TO THE UNPRACTISED STUDENT.

Tue 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
Spiderwort, 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-
Jicial Key to the Natural Orders, p. xvii. Having flowers, it is evident the plant
belongs to the great series of Phenogamous 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 IT. 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 sufficient, and easy to verify. Take first the
stem; is it formed on the exogenous or endogenous plan? 4A 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 the
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. Monocaigledangus or
Endogenous Plants.

We have next to refer it to its proper Order under this Class, lichen is readily
done vy following the successive subdivisions in the Artificial Key. The first

division is into three groups, marked A. IB. 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, &e. 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
Commelynacee. 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 has 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. 286), 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-
nus, whose nante is indicated by the abbreviation L.

Whenever an order comprises several genera, a synopsis of them is given, like
that of Ranunculacee, 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, &e.

Sometimes a genus embraces two or more strongly marked sections, or Sub-
genera, Which are designated by the mark § followed by aname. 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

oped before the leaves; which are ternately divided, the lateral divisions 2-part-
ed, the middle one stalked and 3-parted, the segments deeply once or twice cleft
into narrowly linear and acute lobes; lobes of the involucre like those of the

leaves, at the base all united into a shallow cup; sepals 5—7, purplish, spread-

RANUNCULACE. (CROWFOOT FAMILY.) 5
; a
gether, opposite or whorled, and forming an involucre remote from the flower.
(Name from dvepos, the wind, because the flower was thought to open only when
the wind blows.)

« Pistils many, crowded in a very dense head, clothed with long matted wool in fruit :
sepals downy or silky underneath.

1. A. parviflora, Michx. (Smarz Anemone.) Somewhat pubescent ;
stem slender and simple, one-flowered ; leaves roundish, 3-parted, their divisions
wedge-shaped, crenate-lobed ; involucre of 2 almost sessile leaves; sepals 6, oval,
whitish ; head of fruit globular.— Lake Superior ; ; thence soptiwstl. Plant
2-12! high.

2. A. multifida, DC. ie CLEFT ANEMONE.) Silky-hairy ; prin-
cipal involucre 2—3-leaved, bearing one naked and one or two 2-leaved pedun-
cles; leaves of the involucre short-petioled, similar to the root-leaves, twice or
thrice 3-parted and cleft, their divisions linear ; sepals 5—8, obtuse, red, sometimes
greenish-yellow or whitish ; head of fruit spherical or oval.—Rocks, Western
Vermont and Northern New York, Lake Superior, &c.: rare. June.— Plant
6’-12' high: sepals 3/ long.

3. A. cylindrica, Gray. (Lone-rrvitED ANEMONE.) Slender,
clothed with silky hairs; flowers 2-6, on very long and upright naked pedun-
cles; leaves of the Solaare long-petioled, twice or thrice as many as the flower-
stalks, 3-divided ; their divisions wedge-shaped, the lateral 2-parted, the middle
one 3-cleft; fober cut and toothed at the apex; sepals 5, obtuse, greenish-white ;
head of TR cylindrical (1! long).— Sandy or dry woods, Massachusetts and
Rhode Island to Wisconsin and Illinois. May.—Plant 1°-2° high. Pedun-
cles 7/—12! long, all appearing together from the same involucre, and naked
throughout, or sometimes part of them with involucels, as in No. 4.

4. A. Virgimiama, L. (Tarr Anemone.) Hairy; principal involucre
3-leaved ; the leaves long-petioled, 3-parted ; their divisions ovate-lanceolate, pointed,
cut-serrate, the lateral 2-parted, the middle 3-cleft; peduncles elongated, the
earliest naked, the others with a 2-leaved involucel at the middle; sepals 5, acute.
greenish (in one variety white and obtuse) ; head of fruit oval or oblong. — Woods
and meadows ; common. June-August.— Plant 2°-3° high; the upright pe-
duncles 6/—12' long. In this and the next species the first flower-stalk is leaf-
less ; but from the same involucre soon proceed one or two lateral ones, which

are 2-leaved at the middle ; these partial involucres in turn giving rise to similar

peduncles, thus producing a succession of flowers through the whole summer.

* * Pistils fewer, in a rather loose head, hairy or pubescent.

5. A. Pennsylvamica, L. (Pennsyivanian Anemone.) Hairy,
involucres (or stem-leaves) sessile; the primary ones 3-leaved, bearing a naked
peduncle, and soon a pair of branches or peduncles with a 2-leaved involucre
at the middle, which branch similarly in turn; leaves broadly wedge-shaped, 3-
cleft, cut and toothed ; radical leaves 5—7-parted or cleft ; sepals obovate, white ;
head of fruit spherical; the carpels flat, orbicular, hairy.— W. New England
to Ohio and Wisconsin. June-Aug.— Plant rather hairy, 6! high when it be-

gins to blossom, but continuing to produce branches, each terminated by a naked

peduncle, through the summer ; flowers 14/ broad, handsome.
1*

RANUNCULACES. (CROWFOOT FAMILY.)

6. A. memordésa, L. (Wixp-riowrr. Woop ANEMONE.) Low,

_ smooth ; stem perfectly simple ; flower single on a naked peduncle ; leaves of the
involucre 8, long-petioled, 3-divided, toothed and cut ; the lateral divisions often
(var. QUINQUEFOLIA) 2-parted; radical leaf single ; sepals 4-7, oval, white,

sometimes tinged with purple outside; carpels only 15-20, oblong, with a
hooked heak.— Margin of woods. April, May.— A delicate and pretty vernal
species; the spreading flower 1/ broad. (Eu.)

5. HEPATICA 9 Dill. Liver-tear. Heparioa.

Involucre simple and 3-leaved, very close to the flower, so as to resemble a
calyx ; otherwise as in Anemone (of which this genus may be viewed as only a
section). — Leaves all radical, heart-shaped and 3-lobed, thickish and persistent
through the winter, the new ones appearing later than the flowers. Flowers
single, on hairy scapes. (Name from a fancied resemblance to the liver in the
shape of the leaves.)

1. Hi. triloba, Chaix. (Rounp-topep Heparica.) Leaves with 3
ovate obtuse or rounded lobes; those of the involucre also obtuse. — Woods :
common ; flowering soon after the snow leaves the ground in spring. Sepals
6-9, blue, purplish, or nearly white. Achenia several, in a small loose head,
ovate-oblong, pointed, hairy. Lobes of the leaves “usually very obtuse, or
rounded. (Eu.) :

2. Hi. acutiloba, DC. (Smarr-topep Heparica.) Leaves with 3
ovate and pointed lobes, or sometimes 5-lobed ; those of the involucre acute or
acutish. — Woods, Vermont and New York to Wisconsin. Sepals 7-12, pale
‘purple, pink, or nearly white. Perhaps runs into No. 1.

6. THALICTRUM, Toun. Meavow-Ruz.

Sepals 4 or more, petal-like or greenish. Petals none. Achenia 4-15, tipped
by the stigma or short style, grooved or ribbed, or else inflated. Seed suspend-
ed. — Perennials, with 2-—3-ternately compound leaves, the divisions and the
leaflets stalked. Flowers in corymbs or panicles, often polygamous. (Deriva-
tion obscure.)

* Stem-leaves forming an involucre at the summit, as in Anemone: root tuberots-
thickened and clustered: flowers perfect: fruits sessile, grooved.

1. I. amemonoides, Michx. (Ruz-Anemonz.) Low; root-leaves
twice or thrice 3-divided; the leaflets and the long-stalked leaflets of the invo-
lucre obtusely 3-lobed at the apex; flowers few in a simple umbel. (Anemone
thalictroides, Z., Bigel.) Woods: common. April, May.—A pretty plant, —
more like Anemone than Thalictrum in aspect. The stem bears 2 or 3 leaves
at the very summit, like those from the root, but without the common petiole,
so that they seem like a whorl of long-stalked simple leaves. Sepals 7-10,
half an inch long, not falling off before the stamens, white, or tinged with pink.
Pistils several in a little head, tipped with a flat stigma.

% % Stem-leaves scattered, 3-4 times compound: root fibrous: flowers diccious or

gravelly dry soil, Maine to Wisconsin and southward, but rare west of the Alle-
ghanies. June-Aug.— Stems at first simple. Corolla of the large flowers 1/

Susorper I]. PAPILIONACE®. Tue prover Purse Famiry.

Calyx of 5 sepals, more or less united, often unequally so. Corolla pe-
rigynous (inserted into the base of the calyx), of 5 irregular petals (or very
rarely fewer), imbricated in the bud, more or less distinctly papilionaceous,
i.e. with the upper or odd petal, called the vezillum or standard, larger
than the others and enclosing them in the bud, usually turned backward or
spreading; the two lateral ones, called the wings, oblique and exterior to
the two lower petals, which last are connivent and commonly more or less
coherent by their anterior edges, forming a body named the carina or keel,
from its resemblance to the keel or prow of a boat, and which usually en-
closes the stamens and pistil. Stamens 10, very rarely 5, inserted with the
corolla, monadelphous, diadelphous (mostly with 9 united in one set in a
tube which is cleft on the upper side, i.e. next the standard, and the tenth
or upper one separate), or occasionally distinct. Ovary 1-celled, sometimes
2-celled by an infolding of one of the sutures, or transversely many-celled
by cross-division into joints: style simple: ovules amphitropous, very rare-
ly anatropous. Cotyledons large, thick or thickish: radicle almost always
incurved. — Leaves simple or simply compound, the earliest ones in germi-
nation usually opposite, the rest alternate : leaflets almost always quite en-
tire. Flowers perfect, solitary and axillary, or in spikes, racemes, or pan-
icles.

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 Phzenogamous plants,
divided by the corolla into three suborders, only two of which are repre-
sented in the Northern United States.

Suporper I. TUB ULIFL ORR.

Corolla tubular in all the perfect flowers, regularly 5- (rarely 8 —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 Tubuli ore,
taken from the styles, require a magnifying-plass 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. ) =

Orver 74. SCROPHULARIACEZ. (Fieworr Famiry.)

Chiefly herbs, with didynamous or diandrous (or very rarely 5 perfect) sta-
mens inserted on the tube of the 2-lipped or more or less irregular corolla, the
lobes of which are imbricated in the bud: fruit a 2-celled and usually many-
seeded pod with the placenta in the axis: seeds anatropous with a small em-
bryo in copious albumen. — Style single: stigma entire or 2-lobed. Leaves
and inflorescence various; but the flowers not terminal in any genuine rep-
resentatives of the order.— A large order of bitterish, some of them nar-
cotic-poisonous plants, represented by two great groups (which are not differ-
ent enough to be classed as suborders*) ;— to which an anomalous genus
(Gelsemium) is appended, since no better place has yet been found for it.

* The technical distinction between the so-called suborders is principally in the estivation
of the corolla, which is not likely to be entirely constant. Some years ago, my former pupil,
Mr. Henry James Clark, showed me that in Mimulus one or both of the lateral lobes of the
lower lip are occasionally exterior in the bud, and I haye since noticed a similar exception in
anomalous Pentstemon.

The plants of Tribes 8, 9, and 10 (which incline to turn blackish in drying), are most, if not all,
of them partial root-parasites. This has been for some time known in Tribe 10; and has lately
been shown to be the case in Gerardia also, by Mr. Jacob Stauffer, of Mount Joy, Pennsylvania.

ge erect seed. — Albumen mostly none. Embryo straight (except in Seu-
tellaria): radicle at the base of the fruit. Upper lip of the corolla 2-
lobed or sometimes entire ; the lower 3-lobed. Stamens, as in all the al-
hed families, inserted on the tube of the corolla. Style 2-lobed at the
apex. Flowers axillary, chiefly in cymose clusters, which are often aggre-
gated in terminal spikes or racemes. Foliage mostly dotted with small
glands containing a volatile oil, upon which depends the warmth and aro-
ma of most of the plants of this large and well-known family. (More abun-
dant in the Old World than the New. One third of our genera and many
of the species are merely introduced plants.)

5-merous and 5-androus flowers, in aspect between the foregoing and the next
order; but the ovary ovoid and entire, 1-celled,, with 2 parietal 4 —many-
ovuled placente. — Style 2-cleft above. Pod globular or oblong, 2-valved,
4—many-seeded. Seeds reticulated or pitted, amphitropous, with a small
embryo in cartilaginous albumen. — Flowers chiefly blue or white, in one-
sided cymes or racemes, which are mostly coiled from the apex when young,
and bractless, as in the Borage F anily. (A small order of plants, of no
marked properties, some of them cultivated for ornament.)

Moquin, &c.) — Low grounds and moist sandy shores, Vermont to Wisconsin,
Illinois, and southward, especially westward. Aug., Sept.— Var. CONCATE-
NATA is a form with the lower clusters in the fertile plant forming thickish dis-
tant heads (4!—4/ in diameter) in the axils of the leaves; the stems often low
and spreading or decumbent. — A very variable plant, as to inflorescence, height
(1°-6° high), the size and shape of the leaves (1/-5! long, the petioles often of
the same length), the bracts more or less awl-shaped, equalling or exceeding the
fruit (which is that of Amarantus): but all are forms of one species. ‘The
sterile plant is Acnida rusocarpa, Mich«., or was mixed with it in Michaux’s
collection, but not the fertile; for the fruit of the present plant is neither obtuse-

angled, rugose, nor indehiscent. Besides, that name is unmeaning. In estab-
lishing this zenus, therefore, as Moquin clearly would have done had he exam-
ined the .1pe fruit, I adopt Nuttall’s specific name.

4. ACN iD A, L. Warer-Hemp.

Fruit a fleshy and indchiscent utricle, 3—5-angled, the angles often rugose or
tubercled-crested. Stigmas 3-5, shorter than the ovary, linear-awl-shaped.
Flowers in rather loose panicled spikes. Otherwise as in the last genus. (Name
formed of a privative and «vidy, a nettle.)

‘1, A. canndabina, L. Leaves elongated-lanceolate or ovate-lanceolate,
long-peti .; fruit globular (1$/"-2" long), much exceeding the pointless
bracts. «, . “alt-marshes on the coast, Massachusetts to Virginia and south-
ward. Aug. -Oct.— Plant 3°-6° high. — Probably the only species ; for A.
rusocarpa, Miche, is certainly to be divided between this and Montelia tamaris-
cina; and A. tuberculata, Moguin, is likely to be one or the other.

5. IRESINE, P. Browne. IRESINE.

Flowers mostly polygamous or dicecious, 3-bracted. Calyx of 5 sepals. Sta-
mens mostly 5: filaments slender, united into a short cup at the base: anthers
l-celled, ovate. Fruit a globular utricle, not opening. — Herbs, with opposite
petioled leaves, and minute scarious white flowers crowded into clusters or
spiked and branching panicles, the calyx, &c. often bearing long wool (whence
the name, from efpeovdyn, a branch entwined with fillets of wool borne in pro-
cessions at festivals.)

1. I. celosioides, L. Nearly glabrous, erect, slender (2°-4° high) ;
leaves ovate-lanceolate ; panicles narrow, naked ; bracts and calyx silvery-white,
the latter woolly at the base. @—Dry banks, Ohio, Kentucky, and south-
ward. Sept.

thin utricle. Filaments united into a tube, bearing 5 oblong 1-celled anthers,
and as many sterile strap-shaped appendages. — Hairy or woolly herbs, with

lanceolate, silky-downy beneath ; spikelets crowded into an interrupted spike;
calyx very woolly. @ — Illinois, i in Mason and Cass Counties, Mead. Aug. —_

retain more or less down on the under surface at maturity. — The species of this
and the following section often bear cone-like excrescences on the ends of the
branches, formed of closely imbricated leaves, probably occasioned by the punc-
ture of insects.

P. nicra, L., was admitted by the elder Michaux into his Flora, without any
mention of its tedhtiey. It was afterwards published by his son, under the name
of P. Hudssnica: 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. pILATATA, Ait., the well-known pyramidal LomBarpy PorLar, has
been extensively introduced as an ornamental tree, and is found in the vicinity

2. ZANNICHELLIA, Micheli. Hornep Ponpweup.

Flowers moneecious, sessile, naked, usually both kinds from the same axil:
the sterile consisting of a single a ce with a slender filament bearing a 2-4-
celled anther; the fertile of 2-5 (usually 4) sessile pistils in the same cup-
shaped levoldne, forming obliquely oblong nutlets in fruit, beaked with a short
style, which is tipped by an obliquely disk-shaped or somewhat 2-lobed stigma.
Seed orthotropous, suspended, straight. Cotyledon taper, bent and coiled up.
— Slender branching herbs, growing under water, with very slender stems, op-
posite or alternate long and linear thread-form entire leaves, and sheathing
membranous stipules. (Named in honor of Zannichelli, a Venctian botanist.)

1. Z paldistris, L. Style at least half as long as the fruit, which is flat-
tish, somewhat incurved, even, or occasionally more or less toothed on the back
(not wing-margined in our plant), nearly sessile, or, in var. PEDUNCULATA, begh
the cluster and the separate fruits evidently peduncled.— Ponds and slow
streams; ratherrare. July. (Eu.)

ing of single ovate or oval 1-celled sessile anthers, as large as the ovaries, and
containing a tuft of threads in place of ordinary pollen: the fertile of single

_ovate-oblong ovaries attached near their apex, tapering upward into an awl-
shaped style, and containing a pendulous orthotropous ovule: stigmas 2, long
and bristle-form, deciduous. Utricle bursting irregularly, enclosing an oblong
longitudinally ribbed seed (or nutlet). Embryo short and thick (proper cotyle-
don almost obsolete), with an open chink or cleft its whole length, from which
protrudes a doubly curved slender plumule. — Grass-like marine herbs, growing
wholly under water, with a jointed creeping stem or roo istock, sheathed by the
bases of the very long and linear, obtuse, entire, grass-like, ribbon-shaped. leaves
(whence the name, from {wornp, a band).

1. Z marina, L. Leaves obscurely 3-5-nerved. — Common in bays
along the coast ; in water of 5°- 15° deep. Aug. (Eu.)

4. RUPPIA, L. Drrcu-crass.

Flowers perfect, 2 or more approximated on a slender spadix, which is at
first enclosed in the sheathing spathe-like base of a leaf, naked (entirely desti-
tute of floral envelopes), consisting of 2 sessile stamens, each with 2 large and
separate anther-cells and 4 small sessile ovaries, with a single campylotropous
suspended ovule: stigma sessile, depressed. Fruit of little obliquely-ovate
pointed drupes, each raised on a slender stalk which appears after flowering ;
the spadix itself also then raised on an elongated thread-form peduncle. Em-
bryo ovoid, with a short and pointed plumule from the upper end, by the side
of the short cotyledon. — Marine herbs, growing under water, with long and
thread-like forking stems, slender and almost capillary alternate leaves with a
dilated sheathing base. Flowers rising to the surface at the tite of expansion.

Flowers perfect, spiked. Sepals 4, rounded, valvate in the bud. Stamens 4,
nearly sessile, opposite the sepals: anthers 2-celled. Ovaries 4 (rarely only
one), with an ascending campylotropous ovule: stigma sessile or on a short
style. Nutlets drupe-like when fresh, more or less compressed. Seed curved
or cochleate ; the radicular end of the embryo pointing downwards. — Herbs
of fresh or barely brackish ponds and streams, with jointed creeping and root-
ing stems, and 2-ranked pellucid leaves, which are usually alternate or imper-
fectly opposite ; the upper sometimes dilated, of a firmer texture, and floating.

Var. Niagarémsis (P. Niagarensis, Tuckerm.), from the brink of the cat-

wants the floating leaves, and is common in decp water. © (Eu.)

Var.? flttitams. Uppermost leaves floating on distinct but rarely very long -
petioles, varying from oblong-lanceolate and acute at each end to ovate and
obtuse or heart-shaped (2/-4! long). P. fluitans, Roth., &e.; and here I would
refer P. pulcher? and P. amplifolius, Tuckerm. P. rufescens, Schrader, is a
narrow-leaved form, with smaller fruit, &c., cither without floating leaves (P.
obrutus, Wood) or with them, of a brownish or reddish tinge, and verging to the
larger forms of No. 12.— Mostly in rather deep water; common northward.
Distinguished from P. natans by its broader and large immersed leaves, and
keeled fruit. Probably P. fluitans may be separated from P. lucens, and perhaps
several species with floating leaves may be here confounded ; the forms are di-
verse, and the fruit differs in the strength of the keels, &e. Se J have not been
able to limit them. (Eu.)

keeled when dry (one half smaller than in the preceding). (P. gramineus, L.
in part, Fries, gc. P. Claytonii, Tuckerm.) — In shallow pools and ditches, as
well as streams ; common. (Eu.)

P. crfsrus, L., I have not seen in this country. 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. pkxsus was admitted into the first edition on the authority of Beck from
Schweinitz. I apprehend some mistake about it. The species, if in the coun-
try, may be known by its leaves being all opposite and without stipules.

beset with pellucid and veinless, 1-nerved, sessile, whorled or opposite leaves.
The staminate flowers (which are rarely seen) commonly break off, as in Val-
lisneria, and float on the surface, where they expand and shed their pollen
around the stigmas of the fertile flowers, which are raised to the surface by the
excessively prolonged calyx-tube, varying in length according to the depth of
the water. (Name formed of dv, throughout, and a@yapts, without charms, being
rather homely water-weeds.) : .

1. A. Camadémsis, Planchon. Leaves in threes or fours, or the lower
opposite, varying from linear to oval-oblong, obscurely and minutely serrulate ;
stigmas more or less 2-lobed. (Elodea Canadensis, Michr. Udora Canadensis,
Nutt. Amnacharis Alsinastrum (Babington), Nuttallii, and Canadensis (perhaps
also Chilensis), and also Apalanthe Schweinitzii, Planchon.) — Slow streams
and ponds; common. July. (Eu. ?)

3. VALLISNERIA, Micheli. TaprE-GRass. Er.-crass.

Flowers strictly dicecious : the sterile numerous and crowded in a head on a
conical receptacle, enclosed in an ovate at length 3-valved spathe which is borne
on a very short scape: stamens mostly 3. Fertile flowers solitary and sessile
in a tubular spathe which is borne on an exceedingly long scape. Perianth
(calyx) 3-parted in the sterile flowers ; in the fertile with a linear tube coherent
with the 1-celled ovary, but not extended beyond it, 3-lobed (the lobes obovate) ;

also 3 linear small petals. Stigmas 3, large, nearly sessile, 2-lobed. Ovules-

very numerous on 3 parietal placenta, orthotropous! Fruit elongated, cylin-
drical, berry-like.— Stemless plants, with long and linear grass-like leaves,
growing entirely under water. The staminate clusters being confined to the
bottom of the water by the shortness of the scape, the flower-buds themselves
spontaneously break away from their short pedicels and float on the surface,
where they expand and shed their pollen around the fertile flowers, which are
raised to the surface at this time: afterwards the thread-form fertile scapes (2-4
feet long according to the depth of the water) coil up spirally and draw the ovary
under water to ripen. (Named in honor of Vallisneri, an early Italian botanist.)

mon in slow rivers, &c. August. (Hu.)

Orper 118. BURMANNIACEZE. (Burmannia Famiry.)

Small annual herbs, often with minute and ‘scale-like leaves, or those of the
root grass-like ; the flowers perfect, with a 6-cleft corolla-like perianth, the
tube of which adheres to the 1-celled or 3-celled ovary; stamens 3 and dis-
tinct, opposite the outer divisions of the perianth ; pod many-seeded, the seeds
very minute. — A small chiefly tropical family, of which only one plant is
found within our borders.

1. BURMANNIA, L. (Trrereraiya, Miche.)

Ovary 3-celled, with the thick placente in the axis. Filaments 3, very short.
Style slender: stigma capitate-3-lobed. Pod often 3-winged. (Named for
J. Burmann, an early Dutch botanist.)

1. B. biffdra, L. Stem low and slender (2/-4! high), 2-flowered at the
summit, or soon several-flowered ; perianth (2-3! long) bright blue, 3-winged.

Orper 119. ORCHIDACE®. (Orcuis Fairy.)

Herbs, distinguished by their irregular flowers, 6-merous perianth adherent
to the 1-celled ovary with 3 parietal placente, gynandrous stamens (only 1 or
2), and pollen cohering in waxy or mealy masses. Fruit a 1-celled 3-valved
pod, with innumerable minute seeds, appearing like fine saw-dust. 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. Leaves parallel-nerved. Flowers commonly showy and singular
in shape, either spiked, racemed, or solitary, bracted. A large family, but
sparingly represented in the United States.

* The character by which Endlicher distinguishes this family from the foregoing, viz. by hay-
ing the 8 cells of the ovary opposite the inner divisions of the perianth, is not true of either of
the following genera. Yet, in Lophiola and Aletris, the 3 stigmas, as well as the 8 divisions in-
to which the style splits at maturity, are indeed thus situated: but they stand over the partt-
tions, instead of the cells, and therefore exactly surmount the valves of the loculicidal ped.

ers ; the divisions of the 6-cleft petal-like perianth convolute in the bud in 2
sets, the tube coherent with the 3-celled ovary, and 3 distinct or monadelphous
stamens with extrorse anthers.— Flowers from a 2-leaved spathe, usually
showy and ephemeral. Style single: stigmas 3, alternate with the cells of
the ovary. Pod 3-celled, loculicidal, many-seeded. Seeds anatropous:
embryo straight in fleshy albumen. Rootstocks, tubers, &c. mostly acrid.
— A rather small family, here represented by only two genera.

1. IRIS ae 5A FLOWER-DE-LUCE.

smaller and erect. Stamens distinct, placed before the outer divisions of the
perianth, and under the 3 petal-like stigmas. Pod 3-6-angled. Seeds de-
pressed-flattened. — Perennials with creeping and often tuberous rootstocks,
sword-shaped or grassy leaves, and large showy flowers. (Ipus, the rainbow
deified, anciently applied to this genus on account of the bright and varied
* colors of the blossoms.)

* Stems leafy (1°-3° high), often branching: rootstocks thick : flowers cresttess, the
inner divisions (petals) much smaller than the outer.

1. I. versicolor, L. (Larcer Buvue Frac.) Stem stout, angled on
one side; leaves sword-shaped (§' wide) ; ovary obtusely triangular with the sides
flat ; pod oblong, turgid, with rounded angles. — Wet places ; common, May,
June. — Flowers blue, variegated with green, yellow and white at the base, and
veined with purple.

2. I. Virginica, L. (Sienper Biure Frac.) Stem very slender,
terete ; leaves narrowly linear (4! wide); ovary 3-angled, and each side deeply
2-grooved ; pod triangular, acute at both ends. (I. prismatica, Pursh. I. gra-
cilis, Bigel.) — Marshes, Maine to Virginia, and southward, near the coast.
June. — Flower much smaller than in the last.

* * Low, almost stemless, 1-3-flowered : divisions of the light blue-purple perianth
nearly equal : rootstocks slender, and here and there tuberous-thickened, creeping and
tufted.

3. I. vérma, L. (Dwarr Iris.) Leaves linear, grass-like, rather glau-
cous, the thread-like tube of the perianth about the length of the divisions, which
are all beardless and crestless ; pod triangular.— Wooded hill-sides, Virginia,
Kentucky, and southward. April.

4, I. cristata, Ait. (Cresrep Dwarr Iris.) Leaves lanceolate (3!-

thread-like tube of the perianth, which is 2’ long and considerably exceeds the divis-
ions ; the outer ones crested, but beardless ; pod sharply triangular. — Mountains
of Virginia, Kentucky, and southward. May.

from a fancy that the hogs are fond of rooting it up.)

1. 8S. Bermudiimna, L. Scape winged, naked, or 1-2-leaved; leaves
narrow and grass-like; divisions of the perianth obovate, more or less notched
at the end, and bristle-pointed from the notch. (Leaves of the spathe almost

“Tn arranging the Carices for your work, I have had constantly in view the species compre-
hended within your geographical range, and have framed the sections and subsections with es-
pecial reference to these, without regard to other excluded species belonging, in many cases, to
the same groups, but exhibiting peculiarities which would require the combining characters to
be modified or changed. Indeed, most of my subsections would, in a monograph of the genus,
require to stand as distinct sections, with appropriate subdivisions. I have thought it an as-
sistance to the student to give a leading name to the principal groups, and in some cases have
adopted those already suggested by different authors ; but as I am uncertain whether the char-
acters on which I rely are in accordance with their views, I have cited no authorities under
such subsections. I have endeavored to bring the allied groups (as I understand them) as
nearly together as I could; but this, of course, is not always practicable in any lineal arrange-
ment. It might, however, have been done with much greater satisfaction on a larger and more
comprehensive scale. I have retained the small artificial group Psyllophoree, from its manifest
convenience, but should not have done so ina more philosophical work. Upon the whole, I
am inclined to hope that the present will at least possess this one advantage over the hitherto
more artificial arrangement in general use, — that a student, when acquainted with one species
of a group, will be enabled to recognize the co-species for himself, whilst a merely artificial

enumeration must at times place very incongruous forms in juxtaposition. Any inéreased
difficulty, if such there be, in commencing the study of this vast and intricate genus upon
principles of natural classification, will be amply repaid by the more accurate knowledge of
structure thus obtained, than by a reliance merely on the loose external characters derived
from the number and position of the spikes. I shall be well satisfied if my attempt shall be
an assistance to others in doing far better, hereafter.” Ed. 1.— The additions and alterations

dracea, & C. vesicaria, var. cylindracea, Dew.) —Bogs, New England to Ken-
tucky, and northward. — Less robust than the last.

abruptly contracted into a short cylindrical beak ; scales lanceolate, awnless, or the
upper with a rough awn shorter than the perigynium ; culm slender, obtusely angled,
smooth; leaves and bracts glaucous, often involute, longer than the culm.—

summit; Secnie and bracts glaucous, wide and much longer than the culm. (C.
utriculata, Boott.)—In swamps; common northward, and from Arctic Ameri-
ea to the Pacific. — Differs from the last two in the smooth obtuse-angled culm,
glaucous leaves, and particularly by the awned scale. The var. is the prevailing
form in the United States, and is a larger and stouter plant; but the more ellip-
tical fruit, and awned lower scales, do not appear sufficiently constant to sepa-

very long and, like the narrow leaves, rough and exceeding the rough culm.
(C. bullata, Amer. auth., not of Schk. C. Tuckermani, Dew., Boott.) — Swamps,

in the more numerous and longer fertile spikes, and the larger, more inflated
and membranaceous ascending fruit, with smooth beaks.

only one, sometimes 2, approximated, oblong or cylindrical, stout, sessile or on short

bracts and leaves narrow, about the Jength of the smooth or roughish culm.
(C. cylindrica, Tuckerman, Torr. N. Y. Fl. (excl. syn.), not. of Schw.) — Wet
meadows ; not rare, especially southward. — Well distinguished from the last by
the short and stout, commonly solitary fertile spike, which has a squarrose ap-
pearance at maturity from the widely-spreading fruit; its beak minutely (but
distinctly) serrulate.

Orper 134, GRAMINEE. ‘(Grass Famiry.)

Grasses, with usually hollow stems (culms) closed at the joints, alternate 2-
ranked leaves, their sheaths split or open on. the side opposite the blade; the
hypogynous flowers imbricated with 2-ranked glumes or bracts: the outer pair
(glumes proper, calyx, L.) subtending the spikelet of one or several flow-
ers; the inner pair (palec, outer perianth, R. Br.) enclosing each partic-
we flower, which is usually furnished with 2 or 3 minute hypogynous
scales (sqguamulee, Juss., corolla, Micheli, lodicule, Beauy.). Stamens 1-6,
commonly 3: anthers versatile, 2-celled, the cells distinct. Styles mostly
2 or 2-parted: stigmas hairy or feathery. Ovary 1-celled, 1-ovuled, form-
ing a seed-like grain (caryopsis) in fruit. Embryo small, on the outside
and at the base of the floury albumen. — Roots fibrous. Sheath of the
leaves usually more or less extended above the base of the blade into a
scarious appendage (ligule). Spikelets panicled or spiked. Inner (upper)
palea usually 2-nerved or 2-keeled, therefore probably consisting of two
united.— A vast and most important family, as it furnishes the cereal
grains, and the principal food of cattle, &c.

which it differs in its entire and awnless pales,—an alliance strengthened by
the following remarkable new species which I venture to place in it; — leaving
the genus among the Festucines on account of the technical character, as it
wants the awn, and because it may include Arctophila of Ruprecht, which verges
very close on Colpodium and Glyceria. Fluminia, Fries, or Scolochloa, Link,
(which may occur within our northwestern borders,) is intermediate in character
between Dupontia and Tricuspis, but might perhaps be ranged with Arctophila
in spite of its teeth, of which there are traces in some genuine Glyceriz.)

other kind solitary at the extremity of slender runner-like radical peduncles
(which are more or less sheathed towards the base), much larger than the

others, perfect and fertile, subterranean ; the enwrapping glume and similar —

empty palea many-nerved. Flower oblong or ovoid, pointed. Stamens 3 (small

pistils), and producing, in place of seeds, minute bodies of
homogeneous structure (called spores), in which there is

no embryo, or plantlet anterior to germination.

—*
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 spore-

cases underneath.— Comprises solely the genus 2

1. EQUISETUM, L. Horssram. Scovnine Rusu. (Tab. 14.)

Spore-cases (sporangia, thece) 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 (elaters), 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 oceupying 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.) e

¥Fruit-dots linear or oval-oblong, irregularly scattered on the reticulated veins
of the simple frond, variously diverging, inclined (especially those of the second-
ary reticulations) to approximate in pairs by the side at which the indusium
opens, or to become confluent at their ends, forming crooked lines or angles
(whence the name; from xapzrds, bent, and cwpés, for fruit-dot).

ple frond, borne in pairs on the contiguous sides of the two parallel forks of the
Straight free veins, one on each, but so confluent side by side as to appear like
one, opening by an apparently double indusium down the middle. (The ancient
Greek name, so called because the numerous parallel lines of fruit resemble the

1. LYCOPODIUM, L., Spring. Cxius-Moss. (Tab. 14.)

Spore-cases of one kind (sporangia, much like those of Ophioglossum, only
larger), coriaceous, flattened, usually kidney-shaped, 1-celled, opening by a trans-
yerse line round the margin, thus 2-valved, discharging the subtile spores in the
form of a copious sulphur-colored inflammable powder. — Perennials, with ever-
green 1-nerved leaves, imbricated or crowded in 4-16 ranks. (Name compound-
ed of AvKos, a wolf, and movs, foot, from no obvious resemblance.)

§. 1. Sporangia scattered in the axils of the ordinary and uniform (dark-green and
shining, rigid, about 8-ranked) leaves.

1. KL. lweidulwam, Michx. Stems thick, 2 or 3 times forked, the branches
ascending (6’-12' high); leaves widely spreading or reflexed, linear-lanceolate,
acute, minutely toothed. —-Cold, damp woods; common northward, and south-
ward along the higher Alleghanies. August.

2. SELAGINELLA, Beauy., Spring. (Tab. 14.)

Fructification of two kinds, namely, of spore-cases like those of Lycopodium,
but very minute and oblong or globular, containing reddish or orange-colored
powdery spores; and of 3-4-valved tumid oophoridia, filled by 3.or 4 (rarely 1-
6) much larger globose-angular spores; the latter either intermixed with the
former in the same axils, or solitary (and larger) in the lower axils of the leafy
4-ranked sessile spike. (Name a diminutive of Selago, an ancient name of a
Lycopodium, from which this genus is separated. )

* Leaves all alike, equally imbricated ; those of the spike similar.

1. S. selaginoides. Sterile stems prostrate or creeping, small and slen-
der; the fertile thicker, ascending, simple (1'-3' high); leaves lanceolate, acute,

flaccid ; leaves pellucid-membranaceous, the larger spreading horizontally, ovate,
oblique, mostly obtuse ; the others smaller, appressed, taper-pointed ; those of
the short spikes nearly similar ; oophoridia copious at the lower part of the
spike. (Lycopodium 4podum, L.)— Low, shady places, S. New England,
near the coast, to Virginia, and southward. — A. delicate little plant, resembling
a Moss or Jungermannia.

Orper 138. HYDROPTERIDES. (Marsireaced, R. Br.)

Aquatic eryptogamous plants, of diverse habit, with the fructification borne
at the bases of the leaves, or on submerged branches, consisting of two sorts
of organs, contained in indehiscent or irregularly bursting involucres (sporo-
carps):— here represented by only two genera; one of them, Isoetes,
nearly related to Club-Mosses in structure ; the other, Azolla, much like a

floating Liverwort.

1. ISOETES, L. Quititwort. (Tab. 14.)

Stem a mere succulent base or crown, rooting from underneath, and covered
above with the dilated imbricated bases of the elongated terete awl-shaped or
stalk-like cellular leaves. Sporocarps ovoid and plano-convex, pretty large,
sessile in the axils of the leaves and united with or enveloped by their excavated
dilated base, very thin, traversed internally by transverse threads, forming a
Kind of partitions ; those of the central leaves filled with very minute powdery
grains (analogous to the spores of Lycopodium) ; the exterior filled with larger
spherical-quadrangular spores (oophoridia), at first cohering in fours, their crus-
taceous integument marked by 3 radiant lines. (Name composed of icos, equal,
and ros, year; perhaps intended to indicate that these aquatic plants are un-
changed by the season, i. e. alike the year through.)

1. I. lacwstris, L. Crown or rootstock broad and depressed ; leaves whol-
ly submersed, dark green, rigid and fragile, awl-shaped (2'-6! long), the dilated
base as broad as long; spores (oophoridia) roughish-granulated, scarcely reticu-
lated. — Bottom of ponds and slow streams ; not rare northward. — New Eng-
land specimens agree well with the European plant, and also seem too nearly
like the next. The following species are admitted in deference to authority :
but probably all are forms of one. (Eu.)

2.1. riparia, Engelm. Crown small; leaves slender, soft, yellowish-
8reen (4! -6/ long), the base broader than long; spores minutely farinaceous
and reticulated. — Gravelly banks of the Delaware below Philadelphia, between

high and low water mark, Dr. Zantzinger: and probably throughout the Middle
States.

3. I. Engelimanni, Braun. Leaves long and slender (9/-12! long),
entirely emersed in summer, soft and flaccid, light yellowish-green, the dilated
base longer than broad; spores coarsely farinaceous and reticulated. — Shallow
ponds of the Western States, and southward.

2 AZOLLA, Lam. Azora. (Tab. 14.)

Plant floating free, pinnately branched, clothed with minute imbricated leaves,
appearing like a small Jungermannia : fructification sessile on the under side of
the branches, of 2 sorts. Sporocarps covered at first with an indusium of a
single diaphanous membrane, ovoid ; the smaller kind opening transversely all
round, containing several roundish-angular antheridia ? peltately borne on the
sides of a central erect column: the large or fertile kind bursting irregularly,
filled with numerous spherical sporangia rising from the base on slender stalks,
each containing a few globular spores. (Name said to come from aq, to dry,
and 6)Aq, to kill, being destroyed by dryness.)

1. A. Caroliniana, Willd. Leaves ovate-oblong, obtuse, spreading,
reddish underneath, beset with a few bristles. — Pools and lakes, New York to
Illinois, and southward.— Plant 3! to 1’ broad.— Probably the same as A.
Magellanica of all South America.

MarsfLea MucRONATA and perhaps M. vestira may occur in the western
parts of Illinois and Wisconsin.

Sarvfnta NATANS, L., said by Pursh to grow floating on the surface of
small lakes in W. New York, has not been found by any other person, and prob-
ably does not occur in this country. It is therefore omitted.

MUscT. (MOSSES.) ee. 607

Cuass IV. ANOPHYTES.

Cryptogamous acrogenous plants, growing upwards by
an axis or stem, and usually furnished with distinct leaves
(sometimes the stem and foliage confluent into a frond),
composed of cellular tissue alone.

Orper 139. MUSCI. (Mosszs.*)

Low, tufted plants, always with a stem and distinct (sessile) leaves, pro-
ducing spore-cases which open by a termisial lid (except in Nos. 1-4), and
contain simple spores alone. Reproductive organs of two kinds:+ 1. The
sterile (male) flower, consisting of numerous (4-20) minute cylindrical
sacs (antheridia) which discharge from their apex a mucous fluid filled with
oval particles, and then perish... 2. The fertile flower composed of numer-
ous (4 — 20) flask-like bodies (archegonia, pistillidia), each having a membra-
nous covering (calyptra), terminated by a long cylindrical funnel-mouthed
tube (style). The ripened archegonium (seldom more than one in a flow-
er maturing) becomes the capsule, which is rarely indehiscent or splitting
by 4 longitudinal slits, but usually opens by a lid (operculum) : beneath the
operculum, and arising from the mouth of the capsule, are commonly I or 2
rows of rigid processes (collectively the peristome) which are always some
multiple of four: those of the outer row are called teeth ; those of the

‘inner row, cilia, their intermediate smaller processes, ciliole. An elastic
ring of cells (annulus) lies between the rim of the capsule and operculum.
The powdery particles filling the capsule are spores or sporules. ‘The
thread-like stalk (pedicel) supporting the capsule is inserted into the elon-
gated torus (vaginula) of the flower. The pedicel continued through the
capsule forms the columella ; when enlarged uniformly under the capsule, it
forms an apophysis ; when protuberant on one side only, a struma. The
calyptra separating early at its base is carried up on the apex of the cap-
sule; if it splits on one side it is hood-shaped or cuculliform, if not, it is
mitre-shaped or mitriform. Intermixed with the reproductive organs are
cellular jointed filaments (paraphyses). The leaves surrounding the an-
theridia are called the perigonial leaves ; those around the archegonium or
pedicel, the perichetial leaves.

* By Wiiiam S. Sutrrvant, Esq.

+ That the antheridiwn of Mosses bears the same relation to the archegonium which the
anther does to the pistil in Pheenogamous plants, cannot now reasonably be doubted, although
perhaps not established by direct proof. Fruit is never produced without the co-operation of
both these organs.

concave, with a peculiar reticulation, composed of two kinds of cellules, one kind
(utricles) large, sub-fusiform, colorless, perforated, and lined with a spiral fila-
ment (fibrillose), except in No. 10; the other kind (ducts) much smaller, linear,
chlorophyllose, running between the contiguous walls of the utricles and form-
ing the angular-serpentine network. (Zddyvos, the ancient name.) Cross-sec-
tions of the leaf (see Sulliv. in Mem. Amer. Acad. IV. p. 174. t. 4. B.), showing
the form and relative position of the utricles and ducts, are of service in deter-
mining the species, as follows :—

* Ducts somewhat elliptical, situated centrally between the angular-rotund utricles,
and not extending to either surface of the leaf.

HEPATICH. (LIVERWORTS.)

Orper 140. HEPATIC. (Liverworrs.*)

Moss-like plants, of a loose cellular texture, usually procumbent, and emit-
ting rootlets from beneath; the calyptra not separating from the base, but
usually rupturing at the apex; the capsule not opening by a lid, containing
spores usually mixed with elaters (which are thin thread-like cells, contain-
ing one or two spiral fibres). — Vegetation sometimes Jrondose, i. e. the
stem and leaves confluent into an expanded leaf-like mass; sometimes
_ foliaceous, when the leaves are distinct from the stem as in true Mosses,
entire or cleft, 2-ranked, and often with an imperfect or rudimentary row
(amphigasiria) on the under side of the stem. Reproductive organs of two
kinds, viz. antheridia and pistillidia, much as in Mosses (p. 607), variously
situated. The matured pistillidium forms the capsule, which is immersed
in or sessile upon the frond, or borne on a long cellular pedicel, or
attached to the under side of disk-like peduncled receptacles, and dehisees
by irregular openings, by revolute segments at its apex, or lengthwise by
2-4 valves: a columella is rarely present. The perianth is a tubular
organ (sometimes absent), enclosing the calyptra, which is always present,
and directly includes the pistillidium. Surrounding the perianth is the
involucre (occasionally wanting), also a tubular organ, or leaves of particu-
Jar forms. The antheridia in the foliaceous species are situated in the
axils of perigonial leaves; in the frondose species, scattered within the
substance, or sessile upon the surface of the frond, or immersed in sessile
or peduncled disk-like receptacles.

And to p. 174, after Spigelia, add:

9. POLYPREMUM, L. Poryrrewum.

Calyx 4-parted, persistent ; the divisions awl-shaped from a broad scarious-
margined base. Corolla not longer than the calyx, almost wheel-shaped, bearded
in the throat; the 4 lobes imbricated in the bud. Stamens 4, very short: anthers

tened, notched at the apex, loculicidally 2-valved, many-seeded. — A smooth,
diffusely spreading and much-branched small annual, with narrowly linear or
awl-shaped leaves, connected at their base across the stem by a slight stipu-

GELSEMIUM, p. 281 and p. 296.

This genus (according to A. De Candolle, now confirmed by Bentham)
belongs to the Loganiacez, a group connecting various dissimilar orders, viz.
Rubiacex, Scrophulariacex, Apocynacex, and Gentianacex, and which it is
necessary to receive as an order in a general work, but which is here appended
to the first-named order, these plants being essentially “ Rubiacez with a free
ovary.” A second species of Gelsemium has been identified by Bentham in

China (Hong Kong).

G04 ADDITIONS AND CORRECTIONS.

ASCLEPIAS, p. 351.—To p. 353, add:

93. A. Meadii, n. sp. Torr. Very smooth, pale; stem simple (1° high),
bearing a single terminal umbel (on a peduncle 3’ long); leaves all opposite,
sessile, oblong, the upper ovate-oblong or somewhat heart-shaped, obtuse, mu-
cronate, the plane (not wavy) margins and the numerous rather slender pedicels
downy when young; divisions of the grecnish-white corolla oblong-ovate (4”
long), half the length of the pedicel; hoods of the slightly stipitate crown fleshy
below, rounded-truncate at the summit, longer than the thickish incurved horn, fur-
nished with a small sharp tooth at the inner margin on each side towards the
summit. — Augusta, Illinois, Mead.— Leaves about 4 pairs, 13’-23/ long. —
Fruit not seen; so that it is uncertain whether it should stand next to A. Sulli-
vantii or A. obtusifolia.

To 6 A. Nuttalliama, p. 352, add syn. A. Vaseyi, Carey, ined. ;
Engelm. mss.— This I still think most likely to be Nuttall’s original A. lanu-
ginosa, and I possess it from the Upper Missouri, gathered by Dr. Suckley.
Dr. Torrey, however (in Ann. Lye. NV. Y.), took an Acerates for it, perhaps the
same as that taken for Acerates lanuginosa by Dr. Engelmann, which is the
following :—

ACERATES, p. 354. Add:

1}. Ae monocéphala, n. sp. Lapham in herb. Low (6/—12! high),
rather stout, hirsute; leaves lanceolate, almost sessile (about 2! long and 3!
wide) ; umbel solitary and terminal, peduncled, very many-flowered ; divisions
of the greenish corolla oblong (23” long), more than twice the length of the
calyx, several times shorter than the pedicels ; hoods of the crown sessile at the
base of the tube of filaments, strongly concave, oblong, erect, with the obtuse
apex somewhat spreading, equalling the anthers. — Prairies of Wisconsin, Lap-
ham, Mr. Cornell. July.— Intermediate in several respects between A. viridi-
flora and A. longifolia; having the sessile crown of the former, and flowers not
larger than those of the latter. Hoods more cucullate than those of A. viridiflora;
the two small appendages within each, and the still smaller pairs of appendages
alternate with the hoods, more conspicuous than in the last-named species,
otherwise very similar: pollen-masses also thicker and less club-shaped. — A.
longifolia is well distinguished by the raised crown, of broader hoods, much
shorter than the anthers, and by the thick and short pollen-masses. — Should
Dr. Engelmann’s surmise prove correct, this species will bear the name of A.
lanuginosa, Decaisne; while the Asclepias Nuttalliana described above will be
A. Vaseyi, Carey.
