THE complete edition of the ManuaL or THE Botany oF
THe NortHern Unitep 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 Phznogamous 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.

gin on each side towards the summit. — Augusta, Illinois, Mead. — Leaves

whether the species should stand next to A. Sullivantii or A. obtusifolia.

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-massés also thicker and less club-shaped.— A. longifolia is well dis-
tinguished by the raised crown, of broader hoods, much shorter than the
anthers, and by the thick and short pollen-masses.—Should Dr. Engel-
mann’s surmise prove correct (as is most likely), this species will bear the
name of A. lanuginosa, Decaisne.

PREFACE.

‘Tas 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 Jowa 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-
mgly 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. 83, “ Vermont to Wisconsin, northward,” &c. And so of
Western plants; e. g. Isopyrum biternatum, p. 11, “ Ohio, Kentucky, and
westward”; Psoralea argophylla, 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 Shortti and V. Lescurii, p. 88; Sullivantia
Ohionis, p. 144, &e. 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 inéroduced species are distinguished by the specific name be-
ing printed in a different type, namely, in small capitals (e. g. Ranunculus
AORIS, p. 10), while the names of the indigenous species are in full-face
letter (e. g. BB. 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,
T 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 “ (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. divaricatus,
p. 7; Actsa 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. Sutzivant, 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. SuuirvanT 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.t

* 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.

+ The reference ‘t Musc. Bor.-Amer.,”” appended to many new or rare Mosses, is made to an
almost complete arranged collection of the Musct 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 have 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 collecti of the | teal

x 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 LesQqUuUEREUX 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 Phanogamous ar 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 (Jirst 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-
ce Rebuspublicis Foederatis detectorum, conjunctis studiis W. 8. SuLLivant et L. LEsquEREvx,
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, x1

lopes, viz. with both calyx and corolla, and in which the corolla consists of
separate petals (the Palypetalous 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 hin
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 divisiols (+, ++, &.) ; and whenever
there are two or more species under a division, I have ialicized 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
a well-devised Analytical Key; which the learner will find equally certain, and much mere
satisfactory in its results.

xii PREFACE.

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. Foxsom, 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, J am greatly indebted to my
excellent friend and correspondent, M. Goprt 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 Carry,
Esq., now of London, for various emendations in the genus Carex, formerly
elaborated by him for this work; and Dr. EncrLMann 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 Alismew. The renewed and
still more extensive contributions of Mx. 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.

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 precisc-
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-
ficial Key to the Natural Orders, p. xvii. Having flowers, it is evident the plant
belongs to the great series df Phanogamous 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 sufficient, 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 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 IJ. Afonocotyledonous or
Endogenous Plants.

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

xvi DIRECTIONS TO THE UNPRACTISED STUDENT.

division is into three groups, marked A. BB. and C. Of these B. alone has
“fowers 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 spadizx.”” 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 8 green sepals, and 3 colored petals, and no glumaceous or husky
bracté, 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—38-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 agreemcnt, 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 name 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 detcr-
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 aname. For example,
Cimicifuga, p. 14, has two subgenera, § 1. Maocrotys, 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 glabra, the Smooth Sumac, &c.

cross. Stamens 6, two of them inserted lower down and shorter. Pod
2-celled by a thin partition stretched between the 2 marginal placente,
from which when ripe the valves separate, either much longer than broad
(a silique), or short (a silicle or pouch), sometimes indehiscent and nut-like
(nucumeniaceous), or separating across into 1-seeded joints (lomentaceous).
Seeds campylotropous, without albumen, filled by the large embryo, which
is curved or folded in various ways: i. e. the cotyledons accumbent, viz.
their margins on one side applied to the radicle, so that the cross-section of
the seed appears thus 0G ; or else incumbent, viz. the back of one cotyle-
don applied to the radicle, thus of). In these cases the cotyledons are
plane ; but they may be folded upon themselves, as in Mustard, where they
are conduplicate, thus 6. In Leavenworthia alone the whole embryo is
straight. — Leaves alternate, no stipules. Flowers in terminal racemes or
corymbs: pedicels not bracted.— A large and very natural family, of

176 DIPSACEH. (TEASEL FAMILY.)

a rather short tube to the corolla, the limb of which is nearly regular,

Orper 58. DIPSACE. (Teaser Famrty.)

Herbs, with opposite or whorled leaves, no stipules, and the flowers in
dense heads, surrounded by an involucre, as in the Composite Family ; but
the stamens are distinct, and the suspended seed has albumen. — Represented
by the Scabious (cultivated) and the genus

1. DEIPSACUWS, Town. Teaser.

Involucre many-leaved, longer than the chaffy leafy-tipped and pointed bracts
among the densely capitate flowers: each flower with a 4-leaved calyx-like in-
volucel investing the ovary and fruit (achenium). Calyx-tube coherent with
the ovary, the limb cup-shaped, without » pappus. Corolla nearly regular, .
4-cleft. Stamens 4, inserted on the corolla. Style slender. — Stout and coarse
biennials, hairy or prickly, with large oblong heads. (Name from dupdao,
to thirst, probably because the united cup-shaped bases of the leaves in some
species hold water.)

1. D. sytvéstris, Mill. (Witp Traset.) Prickly; leaves lance-oblong;
leaves of the involucre slender, longer than the head; bracts (chaff) tapering

into a long flexible awn w.th a straight point.— Road-sides: rather rare. (Nat.
from Eu.) Suspected to be the original of

D. Fuir.onom, the cultivated Futter’s Traszt, which ‘has a shorter invo-
lucre, and stiff chaff to the heads, with hooked points, — used for raising’ a nap
upon woollen cloth.

Orper 59. COMPOSITAE. (Composite Famtry.)

Flowers in a close head (the compound flower of the older botanists), upon
a common receptacle, surrounded by an involucre, with 5 (rarely 4) stamens
inserted on the corolla, their anthers united in a tube (syngenesious). — Calyx-
tube united with the 1-celled ovary, the limb (called a pappus) crowning
its summit in the form of bristles, awns, scales, teeth, &c., or cup-shaped, or
else entirely absent. Corolla either strap-shaped or tubular; in the latter
chiefly 5-lobed, valvate in the bud, the veins bordering the margins of the
lobes. Style 2-cleft at the apex. Fruit seed-like (achenium), dry, con-
taining a single erect anatropous seed, with no albumen.— An immense
family, chiefly herbs in temperate regions, without stipules, with perfect,
polygamous, monecious or diccious flowers. The flowers with a strap-
shaped (ligulate) corolla are called rays or ray-flowers: 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 Phenogamous plants,
divided by the corolla into three suborders, only two of ‘anil are repre-
sented in the Northern United States.

Susorper I. TUBULIFLOR.

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 Tubuliflore,
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.)

subterranean or nearly so, very short, scaly, often branched, each branch sending
up 1~3 slender one-flowered scapes (3'~—5! high) ; divisions of the calyx lance-awl-

Orver 74. SCROPHULARIACER. (Fiewort Famry.)

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 disti the so-called suborders is principally in the sestivation
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 have 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

neous in fields and about gardens. I have never seen it growing wild: it is

rarely cultivated as a pot-herb.

men.— Annual weeds, of coarse aspect, with alternate and entire petioled leaves,
and small green or purplish flowers in axillary or terminal spiked clusters.
(Name compounded of a privative, papaive, to fade, and avOos, flower, because
the dry calyx and bracts do not wither. The Romans, like the Greeks, wrote
Amarantus, which the early botanists incorrectly altered to Amaranthus.) —-No

1. MI. tamarisecima. (Amarantus tamariscinus, Nutt., & ed. 1. <A.
altissimus & Miamensis, Riddell. Acnida altissima, Michx. herb. A. rusocarpa,
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/— 3! 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, Michx., 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 genus, therefore, as Moquin clearly would have done had he exam-
ined the pe fruit, I adopt Nuttall’s specific name.

4. ACNIDA Pam os Water-Heme.

Fruit a fleshy and indehiscent utricle, 3—5-angled, the angles often rugose or
tubercled-crested. Stigmas 3-5, shorter than the ovary, linear-awl-shaped.

long-petioled ; fruit globular (1}//-2" long), much exceeding the pointless
bracts. (3:— Salt-marshes on the coast, Massachusetts to Virginia and south-
ward. Aug.-Oct.— Plant 3°-6° high. — Probably the only species; for A.
rusocarpa, Michz., is certainly to be divided between this and Montelia tamaris-
cina; and A. tuberculata, Moquin, 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
1-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 elpeotoyy, a branch entwined with fillets of wool borne in pro-
cessions at festivals.)

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

Orver 92. POLYGONACE. (Bucxwueat Famtty.)

Herbs, with alternate leaves, furnished with stipules in the form of sheaths
(ochrez) above the swollen joints of the stem; the flowers mostly perfect,
with a more or less persistent calyx, a 1-celled ovary bearing 2-38 styles or
stigmas, and a single erect orthotropous seed. Embryo curved or straight-
ish, on the outside of the albumen, or rarely in its centre; the radicle
pointing from the hilum and to the apex of the dry seed-like fruit. Sta-
mens 4-12, inserted on the base of the 3—6-cleft calyx. Leaves usually
entire. (The watery juice often acrid, sometimes agreeably acid, as in

P. nigra, L., was admitted by the elder Michaux into his Flora, without any
mention of its locality. It was afterwards published by his son, under the name
of P. Hudsdnica: 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. pizarara, Ait., the well-known pyramidal Lomparpy Poprar, has
been extensively introduced as an ornamental tree, and is found in the vicinity
of all old settlements. :

P. Aupa, L., the ApevLe or WuiTE Porwar of the Old World, is occasion-
ally planted, when it spreads widely by the root, and becomes more common
than is desirable.

it is not worth while to adopt them here, since the flowers and fruit are
rarely met with.

the sterile consisting of a single stamen, with a slender filament bearing a 2- 4-
celled anther; the fertile of 2-5 (usually 4) sessile pistils in the same cup-
shaped involucre, forming obliquely oblong nutlets in fruit, beaked with a short
style, which is tipped by an obliquely disk-shaped or somewhat 2-lobed stigma.

protrudes a doubly curved slender plumule. — Grass-like marine herbs, growing
wholly under water, with a jointed creeping stem or rootstock, sheathed by the
bases of the very long and linear, obtuse, entire, grass-like, ribbon-shaped leaves

separate anther-cells and 4 small sessile ovaries, with u single campylotropous
suspended ovule: stigma sessile, depressed. Fruit of little obliquely-ovate
pointed drupes, each raised on a slender stalk which appears after flowering ;

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.

NAIADACEH., (PONDWEED FAMILY.) 435

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

9. P. przelémgus, Wulf. Leaves elongated-oblong, obtuse at both ends,
half-clasping by the sessile base ; peduncles often much elongated (in deep water
6’—12! long); spike cylindrical, many-flowered ; fruit strongly keeled on the back

ules 2-winged or keeled on the back ; peduncle thickened, especially upwards; spike
elongated, dense ; fruit 1 - 3-kecled on the back.— The proper P. lucens usually
wants the floating leaves, and is common in deep water. (Eu.)

Var.? fitiitams. Uppermost leaves floating on distinct but rarely very long
petioles, varying from oblong-lanccolate and acute at each end to ovate and
obtuse or heart-shaped (2/-4' long). P. fluitans, Roth., &c.; and here I would
refer P. pulcher? and P. amplifolius, Tuckerm. P. rufescens, Schrader, is a
narrow-leaved form, with smaller fruit, &c., either 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, &c. But I have not becn
able to limit them. (Eu.)

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

P. crispus, L., I have not seen in this country. Mr. Tuckerman informs
me that he has seen a specimen in « 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. péNsus was admitted into the first edition on the authority of Beck from

try, may be known by its leaves being all opposite and without stipules.

HYDROCHARIDACES, (FROG’S-BIT FAMILY.) 441

2. ANACHARIS, Rich. (Updra, Nutt.) Warer-weep.

Flowers polygamo-dicecious, solitary and sessile from a sessile and tubular
2-cleft axillary spathe. Sterile flowers small or minute; with 3 sepals, barely
united at the base, and usually 3 similar or narrower petals: filaments short and
monadelphous at the base, or none; anthers 9, oval. Fertile flowers either pis-
tillate or apparently perfect: perianth extended into an extremely long and
capillary tube ; the limb 6-parted; the small lobes (sepals and petals) obovate,
spreading. Stamens 3-6, sometimes merely short sterile filaments, without
anthers, or with impertect ones, sometimes with oblong almost sessile anthers.
Ovary 1-celled, with 3 parietal placente, each bearing a few orthotropous ovules ;
the capillary style coherent with the tube of the perianth: stigmas 8, large, 2-
lobed or notched, exserted. Fruit oblong, coriaceous, few-seeded. — Perennial
slender herbs, growing under water, with elongated branching stems, thickly
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 dyapts, without charms, being
rather homely water-weeds.)

1, A. Camadénsis, 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, Michx. Udora Canadensis,

also Chilensis), and also Apalanthe Schweinitzii, Planchon.) — Slow streams
and ponds; common. July. (Eu. ?)

3 VALLISNERIA » Micheli. Tare-crass. Ep.-crass.

Flowers strictly dicecious : the sterile numerous and crowded in # 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 exccedingly 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 8 linear smal petals. Stigmas 3, large, nearly sessile, 2-lobed. Ovules
very numerous on 3 parietal placente, 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
ander water to ripen. (Named in honor of Vallisneri, an early Italian botanist.)

Orper 119. ORCHIDACE. (Orcuis Famtty.)

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 hav-
ing the 3 cells of the ovary ogposite the inner divisi of the perianth, is not true of either of
the following genera. Yet, in Lophiola and Aletris, the 3 stigmas, as well as the 3 divisions in-
to which the style splits at maturity, are indeed thus situated: but they stand over the parti-
dtons, instead of the cells, and therefore exactly t the valves of the loculicidal pod.

“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 charactérs 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 in a 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
enunieration must at times place very incongruous forms in juxtaposition. Any increased
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
in the present edition are mainly from notes obligingly furnished by Mr. Carey.

in dense tufts. Culms triangular, bearing the spikes in the axils of green and
leaf-like or seale-like bracts; commonly with thin membranaceous sheaths at
the base which enclose more or less of the stalks of the spikes. Leaves grassy,
usually rough on the margins and keel. (A classical’ name, of obscure signifi-
cation ; derived by some from careo, to want, the upper spikes being mostly
sterile; and by others from keipw, to cut, on account of the sharp leaves.)

ular, flower, which is usually furnished with 2 or 3 minute hypogynous
scales (squamule, Juss., corolla, Micheli, lodicule, Beauv.). Stamens 1-6,
commonly 3: anthers versatile, 2-celled, the cells distinct. Styles mostly

which it differs in its entire and awnless palea,—an alliance strengthened by
the following remarkable new species which I venture to place in it;— leaving
the genus among the Festuciness 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 im 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 Glycerie.)

homogeneous structure (called spores), in which there is
no embryo, or plantlet anterior to germination.

Fruit-dots a small collection of sporangia borne on the ends of (or extending
down on) the forked, or rarely simple, free veins, which terminate just within
the margin of the frond, soon becoming confluent laterally, so as to imitate the
marginal continuous line of fructification of Pteris, covered when young by a
continuous (rarely interrupted) rather broad scarious-mcembranaccous indusium
consisting of the reflexed and altered margin of the fruit-bearing pinnule or
division, Fronds once to thrice pinnate ; the fertile ones or fertile divisions nar-

forked and free veins. — Fronds 1-8-pinnate or decompound. (The ancient
Greek name of Ferns, from mrepév, a wing, on account of the prevalent pinnate
or feathery fronds.)

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 kapards, bent, and owpds, for fruit-dot).

Greek name, so called because the numerous parallel lines of fruit resemble the
feet of the centipede, or Scolopendra.)

a vessel, and KAelw, to close, from the singularly rolled up fructification. )

1. O. sensibilis, L.— Moist or wet places, along streams ; common.
July. —A rare abnormal state, in which the pinnz of some of the sterile fronds,
becoming again pinnatifid and more or less contracted, bear some fruit-dots

vertical, furnished with a striate-rayed crest at the apex, and opening by a lon-
gitudinal cleft down the outer side. Sterile fronds linear or thread-like, some-
times forked and cleft (whence the name, from oyia, to slit).

much shorter than the fertile, which bears about 5 pairs of short crowded pinnz
at the apex of a slender stalk (3/-4! high). — Low grounds, pine barrens of New

common. May: fruiting as it unfolds. — This, being Clayton’s plant (as I as-
certained in 1839, both from the Claytonian and Linnean herbaria), must bear
the original Linnzan name, though wrongly described, from young specimens in
which the fructification was thought to be terminal.

3. © cinmamodmea, L. (Crvwamon-Frrn.) * Clothed with rusty
wool when young; sterile fronds smooth when full grown, the lanceolate pinnae
pinnatifid into broadly oblong obtuse divisions ; fertile fronds separate, from the

sterile. —Swamps and low copses; everywhere. May.— Growing in large
bunches ; the fertile fronds in the centre, perfecting fruit as they unfold, 1°- 2°
long, decaying long before the sterile fronds (at length 4°-5° high) get their

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 involueres (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. Quittwort. (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 (cophoridia), at first cohering in fours, their crus-
taceous integument marked by 3 radiant lines. (Name composed of icos, equal,
and éros, year; perhaps intended to indicate that these aquatic plants are un-
changed by the season, i. e. alike the year through.)

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. (Enu.)

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 aw, to dry,
and 8dd@, to kill, being destroyed by dryness.)

1. A. Carolinia&ma, Willd. Leaves ovate-oblong, obtuse, spreading,
reddish underneath, beset with a few bristles. — Pools and lakes, New York to

MarsfLEa MucRONATA and perhaps M. vesrira may occur in the western
parts of Hlinois and Wisconsin.

Satvinia 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.
