TO THE REVISED EDITION, 1863.

The additions and alterations of the Revised Edition of this work, now
issued, are mainly the following.

1. The addition of an entirely new part, entitled Garden Botany,
an Introduction to a Knowledge of the Common Cultivated
Plants : see pp. xxix. - lxxxix. By this, the common exotics, no less
than the wild plants, are made available for botanical classes, which will
be a <jreat convenience in many cases. Most of these cultivated plants
are everywhere common, and generally at hand for botanical illustration ;
and it is desirable that they should be scientifically known and rightly
named. And there is no great difficulty in studying them, if double flow-
ers, and those which are otherwise in a monstrous or unnatural condition,
be avoided, at least by beginners. It is obviously absurd and highly in-
convenient to mix in the cultivated with the wild plants in such a work as
this. But a separate account of the common exotics, annexed and sub-
sidiary to the Botany of the Northern United States, especially in the School
Edition, will doubtless be popular and useful. Directions for the use of
the Garden Botany will be found on p. xvii. and p. xxix.

2. The Analytical Key, p. xvii., upon which the pupil so greatly
depends, has been altogether revised, much simplified, adapted to the
Garden Botany as well as to the Botany of the Northern States, and printed
in a larger type.

3. Numerous corrections in particulars have been made throughout the
body of the work, whenever the required alterations could well be effected
upon the stereotype plates. Many others, suggested by acute and obliging
correspondents, or by my own observation, are necessarily deferred until
the work can be recomposcd.

4. The plants which have been newly detected within our limits, and
one or two which were before accidentally omitted, are enumerated and
characterized in the Addenda, p. xc.

5. Eight plates have been added, crowded with figures, illustrating all
the genera (GC, in number) of Grasses. They are wholly original, having
been drawn from nature and engraved by Mr. Sprague. They will be of
great assistance in the study of this large, difficult, and important family.

The flattering success which the Manual has met with stimulates the
author's endeavors towards its continued improvement; — in regard to
which he still solicits aid from his correspondents.

PREFACE.

This work is designed as a compendious Flora of the Northern portion
of the United States, arranged according to the Natural System, for the
use of students and of practical botanists.

The first edition was hastily prepared to supply a pressing want. Its
plan, having been generally approved, has not been altered, although the
work has been to a great extent rewritten. Its increased size is mainly
owing to the larger geographical area embraced in it, being here extended
southward so as to include Virginia and Kentucky, and westward to t he
Mississippi River.

This southern boundary coincides better than any other geographical
line with the natural division between the cooler-temperate and the wann-
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 live decrees of latitude, and nearlv 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 llora of our district, will be presented in anothi r
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 southtcanf, meaning thereby that the species

VU1 PREFACE.

in question occurs in the States south of Virginia or Kentucky. Thus
Maynolia ylauca, 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, Nupliar
Kalmiana, p. 23, "New England, New York, and northward"; Cardamine
pralensis, p. 33, " Vermont to Wisconsin, northward," &c. And so of
Western plants; e.g. Isopyrum bilcrnatum, p. 11, " Ohio, Kentucky, and
westward " ; Psoralea argophylla, p. 9-4, " Wisconsin and westward " :
Amorpha canescens, p. 95, "Michigan to Wisconsin, and south westward."
2. Where no habitat or range is mentioned, the species is supposed to be
diffused over our whole area, or nearly so, and usually beyond it. 3. When
the species is of local or restricted occurrence, so far as known, the special
habitat is given ; e. g. Vesicaria Shortii and V. Lescurii, p. 38 ; Sullivantia
Ohiunis, p. 144, &c. Except in such cases, the want of space has generally
demanded the omission of particular localities, which are so appropriate
and so useful both in local Floras and in more detailed works, but for
which there is no room in a manual like this.

For the same reason, I could not here undertake to specify the range of
those species which extend beyond the geographical limits of this work, or
beyond the United States. Nevertheless, to facilitate- the comparison of
our flora with that of Europe, I have appended the mark (Eu.) to those
species which are indigenous to both.

Foreign plants which have become denizens of the soil are of course enu-
merated and described along with the genuine indigenous members of our
flora ; but the introduced species are distinguished by the specific name be-
ing printed in a different type, namely, in small capitals (e. g. Ranunculus
acris, p. 10), while the names of the indigenous species are in full-face
letter (e. g. It. repens). 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. Alphonsc. De Candolle,
I have classified our introduced plants as well as I could into two sorts, the
thoroughly naturalized, and the adoentive ; 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 witk
the adventive plants those which De Candolle terms plants cultivated with
out or against man's will.) Accordingly the species naturalized from Europi
we indicated, at the close of the paragraph, by the phrase " (Nat. from

PREFACE. jx

Eu.)": those adventive, or imperfectly naturalized from Europe, by the
phrase " (Adv. from Eu.)," &c.

Such varieties asare 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. iiispidum, p. 30; Vitas 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; Aetata spicata, var. rue Sua, and var. alba, p. 14) ; and they usu-
ally stand at the head of a separate paragraph.

Another important feature of the present edition consists in the plates,
fourteen in number, crowded with figures, illustrating the genera of the six
Cryptogamous Orders (Mosses, Ferns, &c.) embraced in the work. The
eight most elaborate and admirable plates illustrating the Mosses and Liv-
erworts are furnished by my generous friend, Mr. Sullivant, the author
of that portion of this work.* The remaining six plates, devoted to the
Ferns and their allies, were drawn from nature, and executed by Mr.
Isaac Spkaguk.

Mr. Sullivant has included in this edition all the species of Musci
and Ilepatkce known to him as natives of any part of the United States east
of the Mississippi, and has sedulously elaborated the whole anew; not only
laying a broad foundation for a knowledge of North American Muscology,
but furnishing botanical students with facilities for the study of these two
beautiful families of plants such as have never before anywhere been
afforded in a book of this kind.f

* The illustrations of forty of the genera, as indicated in the Explanation of the Plates at
the close of the volume, are entirely original productions of Mr. Sullivant's pencil. Seven of
them represent new species, and for most of the others those species were chosen which have
before been only imperfectly if at all figured. The rest of the genera were taken from Schim-
per, Bischoff, or Hooker, but ameuded 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 " Muse. Bar -Amer.," appended to many new or rare Mosses, is made to an
almost complete arranged collection of the Musci and Hepaticai 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 journjys 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

X PREFACE.

Probably the time is now not far distant when, as the result especially
of the labors and investigations of Prof. Tuckermax upon our Lichenes.
of the Rev. Dr. Curtis upon our Fungi, and of Prof. Harvey upon
our Alga, as well as of Messrs. Sullivant and Lesquereux upon our
Mosses, all our Cryptogamia may be in a similar manner presented to the
student, in the form of a supplementary volume, separate from that com-
prising the Phsenogamous or Flowering Plants.

I have omitted from this edition the concise Introduction to Botanv, 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-Bool' 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 tbw 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, Avith 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. Oakcs in the White Mouutains, of Fendler in New Mexico, and of Wright in Texas The
title of the work is " Musci Boreali-Americani, sire Specimina Exsiccata Muscoruci in Aineri-
cse Rebuspublicis Foederatis detectorum, coujunctis studiis W. S. Sullivant et L. Lesquereux,
1856." Mr. Sullivant's connection with the work extends no further than to a joint and equal
responsibility in the determination of the species. This most extensive and valuable collec-
tion ever made of American Mosses, which has cost much labor and expense, and comprises
nearly 400 species and marked varieties, is published at $ 20 for each set, and will doubtless
be eagerly sought after by Bryologieal students.

PREFACE. XI

lope:?, 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 eases 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 Linnoean 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 more
satisfactory in its results.

Xll 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 (x), and the short sound by the acute accent-mark ('). In respect
to this, my friend, Ml!. Folsom, has obligingly rendered most important
assistance throughout the pages of this volume.

The imperative necessity of economizing space to the utmost, alone has
debarred me from more largely recording my acknowledgments to nu-
merous obliging correspondents, in all parts of the country, who have con-
tributed to this work, either by notes of corrections, observations, or cata-
logues, or by communicating specimens of rare or local plants. In the
comparison of our flora with that of Europe, I am greatly indebted to my
excellent friend and correspondent,. M. Godet of Neuchatel, author of
the Flore du Jura, for a suite of authentically determined plants of that
district, and for a series of acute and very important critical notes upon
many of our own identical or related species.

As to special collaborators in the preparation of the work, in addition to
the acknowledgments made in the preface to the former edition, I have
again to express my particular indebtedness to my friends, John Carey,
Esq., now cf London, for various emendations in the genus Carex, formerly
elaborated by him for this work ; and Dr. Engelmann of St. Louis, for
full notes upon the botany of our Western borders, many critical obser-
vations upon various genera, and for contributing the articles upon Cus-
cuta, Euphorbia, and the three genera of Alismece. The renewed and
still more extensive contributions of Mr. Sullivan r 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 in-atitude 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.

The Student is supposed to have a general acquaintance with the rudiments
of Structural Botany, such as is readily to he 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 Botanica" 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 hlooms the whole summer long.

With a flowering specimen in hand, let the student turn to the following Arti-
ficial Key to the Natural Orders, p. xvii. Having flowers, it is evident the plant
belongs to the great series of Phcenogamoiis 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. xviii.. and of Class II. on p. xxviii.h Without the
seeds, which may not he ripe, — and if they were it might require more skill
than could he 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 1 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, hark, and a ring of wood or woody
tissue between these two : hut 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. Monocotyledonous or
Endogenous Plants.

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

Xvi DIRECTIONS TO THE UNPRACTISED STUDENT.

division is into three groups, marked A. 15. and C. Our plant, baring dis-
tiuct floral envelopes and neither spadix nor glumes, must belong to B., the
Petaloideous Division. This is subdivided into three sections, designated by
stars. The parts of the flower being all separate from each other, our plant
evidently falls under the third section, with three stars, viz: '•*** Perianth
wholly free from the ovary (inferior)." Next, as its perianth consists of three
green sepals and three colored petals, it belongs to the subdivision -*- -*-.
Under this there are four alternatives, based on differences in the pistil.
The numerous distinct pistils exclude the first, the many or several seeds in
each cell exclude the second ; the one-celled ovary, &c, exclude the fourth;
while the third, having a single pistil with a 2-3-celled ovary, and only one
or two ovules or seeds in each cell, agrees with our plant ; which we are thus
brought to conclude must belong to the order Commelynacece. 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, oaly three of them bearing perfect anthers, — all of which is very
different from the plant we arc studying; and 2. Tradescantia (p. 486), with the
characters of which our plant will be found perfectly to accord.

Let the student then proceed to ascertain the Species, of which three are de-
scribed under this genus. Of the two sections, marked with stars ( * ), our
plant belongs to the first, having a sessile umbel. And of its two species, a
comparison with the characters of each fixes our plant as belonging to the first,
viz. T. Virginica.

The abbreviated name or letter after the name of the genus and that of the
species, denotes the founder of the genus or the species ; — in this instance Lin-
naeus, whose name is indicated by the abbreviation L.

Whenever an order comprises several genera, a synopsis of them is given, like
that of Ranunculacaz, p. 2, by the aid of which the student will readily deter-
mine the genus of the plant under examination. The number prefixed to the
name of the genus, in the synopsis, is that under which it stands, farther on, in
the full account. The genera in the synopsis are often ranked under their proper
Tribes, or Suborders, &c. ; and the student will first determine the Tribe, or
other great group to which the plant he is examining belongs, and then the
Genus under that tribe, &c.

Sometimes a genus embraces two or more strongly marked sections, or Sub-
genera, which are designated by the mark § followed by a name. For example,
Cimkifuga, p. 14, has two subgenera, § 1. Mocrotys, and § 2. Cimicifaga proper,
each with its own characters ; and the genus Rhus, p. 7G, 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 ita
generic and its specific name only; as. Cimieijuga racemosa, the Black Snake-
root; Rims glabra, the Smooth Sumac, &C.

ANALYTICAL KEY

TO THE NATURAL ORDERS, Ac. OF ALL THE PLANTS DESCRIBED IN THIS
WORK, BOTH INDIGENOUS AND EXOTIC.

This Artificial Analytical Key is a contrivance to lead the pupil, with a, plant
in his hand to him unknown, by a succession of easy steps, up to the name of
the natural order to which the plant under examination belongs.

The name at the end of the line, to which the student is brought, is that of the
natural order sought, for example : Magnoliace^.

The numbers prefixed to the name indicate the page upon which the order is
described or treated of, for example: 15 (31) Magnoliace^;.

The numbers without parentheses refer to the body of the volume, the indige-
nous Botany of the Northern States. Those within parentheses refer to the
Garden Botany, which is paged in continuation of the Key.

If the plant under examination should be a wild one, the first or unenclosed
number is alone to be regarded, and the pupil will turn to that page in the body
of the volume. But if an exotic, or a plant here known only in cultivation, the
pupil, after reading over the description of the order in the body of the work, as
before, (for this description of course is not repeated,) will turn to the page in
the Garden Botany indicated by the number enclosed in parentheses. If the only
reference is to the Botany of the Northern States, follow that ; for many plants
in cultivation are also among our wild plants.

Although this Key is a purely artificial contrivance, it is a very necessary
one to beginners ; who, however, will very soon get to know the Classes, Sub-
classes, &c. at sight, and, after considerable practice, will by degrees be able to
recognize at a glance all the commonest natural orders in almost any examples
of them they take in hand. The Key is based on the easiest and most obvious
botanical characteristics that can be made to answer the purpose ; yet it will
bring out, one by one, the principal points, especially in the structure of the
flower, by which plants are classified and the natural orders distinguished.

GARDEN BOTANY:

AN INTRODUCTION TO A KNOWLEDGE OF THE

COMMON CULTIVATED PLANTS.

This simple Introduction to a knowledge of the plants commonly cultivated
in this country, whether for use or ornament, is prepared as a useful accom
paniment to the Botany of the Northern United States, and is made as
extensive as the needful limits of such a volume will allow. It will serve the
purpose of enabling pupils to study our ordinary exotic as well as indigenous
plants, to ascertain their names, and to refer them to their place in the system.

It is to be used wholly in connection with the foregoing Artificial Key, p. xv.,
which is arranged to lead the pupil, if he has an exotic or other cultivated plant
in hand, to this Garden Botany, — if a wild plant, to its order in the proper
Botany of the Northern United States. If the cultivated plant be one which is
described in the main body of the work, — as may frequently be the case, —
the analysis will conduct to a reference, " Man. p. . . ," where the plant in ques-
tion may be found described. It is needless to repeat the description of such
species.

For the same reason, the character or brief description of the orders and of
the genera already in the Botany of the Northern United States is not repeated
in the Garden Botany; but a reference, "Manual," or "Man.," followed by
the page, directs the student to the place where the order or the genus, &c. is
characterized.

Since by far the greater part of the names of the genera, &c. of our cultivated
plants occur in the body of the work, where they are duly accentuated to in-
dicate their proper pronunciation, the accents are not introduced here, except
in the case of a few words, for the most part not already in the Manual, which
are particularly liable to be mispronounced.

As this Garden Botany is intended to be used only for exercise in botanical
analysis, an Index of the names of the plants contained in it, for obvious rea-
sons, is purposely omitted.

smooth, the thin leaves with 5 taper-pointed lobes ; flowers gracefully hanging
on long peduncles ; petals orange, with darker stripes and veins.

8. Hibiscus, Man. p. 68. Besides No. 3 there described, the following are
more or less cultivated for ornament.

H. Syriaeus, Tree Hibiscus, called Shrubby Althaea. A hardv
shrub, 8° to 14° high, with smooth wedge-ovate and 3-lobed leaves, and short-
peduncled flowers, red-purple, white, &c, either single or double, in autumn.

posed to cultivate (but which will not answer), grows to a shrub in warm
climates, and has narrower lobes to the leaves, the flower often reddish.

Order CAMELLIACEJE. Camellia Family.

Manual, p. 70. — Two Chinese and Japanese showy-flowered shrubs of this
order are familiar, viz. the Tea-plant, which is rare in green-houses, and the
Camellia, which is very common. They are so much alike that they ought to
belong to the same genus.

1. Thsea Ghinensis, Tea Plant, has rather small white flowers, the pet-
als and the stamens nearly distinct; the anthers roundish.

2. Camellia Japoilica, Camellia, has large flowers (white, pink-red, &c.,
single or double), the base of the petals and of the stamens united together,
and the anthers oblong. The varieties are many : the flowers, produced in
winter, are much prized.

Order AURANTIACEJE. Orange Family.

The shrubs or trees of this order common in cultivation, in houses, &c, are
known by their evergreen alternate leaves, which are pellucid-punctate (i. e.
through a glass they appear as if riddled with small holes), and with a joint
between the blade and the petiole, which last is generally leafy-winged or mar-
gined ; the flowers white and very fragrant ; the stamens rather many in a single
row, on an hypogynous disk. They are all of the genus Citrus, and originally
perhaps of one species.

1. Citrus vulgaris, Bitter Orange, with a broadly winged petiole, the
fruit with a bitter and acid pulp.

C. Aurantium, Sweet Orange, with a narrow wing or margin to the
petiole, and a sweet pulp.

flowers appearing early in the spring, before the narrow and lanceolate leaves.

A. Persica, the Peach, with rose-pink-colored flowers, broadly lance-
olate leaves, and downy-coated fruit.

Var. lsevis, the Nectarine, has the fruit smooth, like a Plum, but came
originally from the Peach.

2. Prunus, Plum, Cherry. Besides Nos. 1, 7, and other species in the
Man. p. Ill, 1 13, the following are common in cultivation : —

P. Armeniaca, the Apricot, with almost sessile white flowers appear-
ing much before the leaves, which are ovate and somewhat cordate, the yel-
lowish fruit with a velvety surface. In this respect it is like the preceding
genus ; but the flowers, the smooth stone, &c. are as in the Plum.

P. Domestica, the Garden Plum, of many varieties, has thornless
branches and lanceolate-ovate leaves ; it is thought to be a long-cultivated
production of P. instititia, the Bullace Plum, and this a variety of the Sloe,
Man. p. 112.

P. Cerasus, the Garden Cherry, with ovate-lanceolate or oblong-
ovate smooth and veiny leaves, and flowers in sessile umbels, opening at the
same time as the leaves ; this is the original stock as well of the Oxheart
or Duke Cherry as of the Sour Cherry, Morello, &c.

3. Poterium Sanguisorba, Garden Burnet. A common low peren-
nial in country gardens, with small and ovate deeply-toothed leaflets, and a
head of greenish or purplish flowers, the lower ones staminate, the upper ones
pistillate.

4. Kerria Japonica, is called Corchorus in the gardens, where it is a
'common shrub, with ovate and pointed coarsely toothed leaves, and full
double yellow flowers. The state with single or natural flowers has lately
been introduced from Japan.

exotics are cultivated for ornament.

* Shrubs or v.ndershrubs.

S. trilobata. Low shrub, with recurved branches ; leaves smooth, glau-
cous, rounded, and cut-lobed ; flowers very many in umbel-like corymbs,
white, showy.

S. hypericifolia, Italian May, or St. Peter's Wreath. Shrub,

lobed at the end ; flowers small, white, in small umbels.

S. Douglasii, of Oregon, is coming into the gardens : it resembles S.
tomentosa (Man. p. 114), but has longer, narrower, and blunter leaves, and
deeper rose-purple flowers.

GARDEN BOTANY. xlvii

S. sorbifolia, with pinnate leaves, oblong-lanceolate and acuminate
sharply serrate leaflets, and a large panicle of white flowers.

* * Herbs, perennial.

S. TJlmaria, English Meadow-Sweet. Leaves pinnate with a large
3-lobed leaflet at the end, and smaller lateral ones, also minute ones inter-
mixed, whitish-downy underneath ; flowers yellowish-white in a compound
cyme, sometimes double.

S. Filipendula, Deopwoiit. Root fibrous, some of them swollen
below ; leaves mostly radical, smooth and green both sides, with very many
small pinnatifid or cut leaflets ; flowers fewer and larger than in the last, white
• often tipped with reddish ; both single and double-flowered.

6. Potentilla, Cinquefoil. Man. p. 118. The three following red-flow-
ered, perennial, digitate-leaved species are rather common in gardens, where
they are much crossed and mixed. The first is from the Mexican, the two
others from the Himalajan Mountains.

P. kema'toehrus. Silky or velvety ; leaflets 7 or 5 on the lower, 5 and
3 on the upper leaves ; flowers deep red or crimson.

P. Nepaleiisis. Leaflets green both sides, 5 or only 3 in the upper

leaves ; flowers dark purple-crimson or brown-red.

P. recta : a coarse, hirsute, erect, yellow-flowered species ; leaflets 5 or
7, digitate, narrowly cuneate-oblong, coarsely toothed.

7. Fragaria, Strawberry. Man p. 119. The originals of the cultivated
varieties are mainly these : —

P. vesca yields the Alpine Strawberry, the Perpetual, &c, with
small, very fragrant fruit.

P. elatior of Europe, the Hautbois, a taller plant, with calyx strongly
reflexed away from the fruit, which is deep red with a peculiar musky odor.

P. Virginiana, the parent of the American Scarlet, and similar
sorts; and its crosses with the next have given origin to the Pine-apple, and
the greater part of the large sorts now cultivated.

P. Chilensis, with thick leaves very silky underneath, and the large
fruit erect in ripening (instead of hanging as in the rest), is the parent of the
Queen Victoria and Wilmot varieties, &c.

P. Indica has creeping leafy stems, yellow flowers, and tasteless fruit.

8- Rubus Idseus, the Garden Raspberrt, is very much like our wild
Red R. (Man. p. 121), but is taller, larger-leaved, the prickles hooked, and
the fruit larger and firmer, pale red, amber-colored, &c.

9. Rosa, Rose. Man. p. 122. Besides the Sweet-Brier, and the varie-
ties of our wild Prairie Rose (already described), the common cultivated
Roses come from the following. But many of them, especially the tender
ones, are so mixed and altered by long cultivation, that it is difficult, if not
impossible, for the student to refer them to their true types.

* Styles not projecting out of the calyx-cup nor cohering.

P. cinnamomea, Cinnamon Rose. Tall, 5° to 8° high, with brownish-
red bark, and some straightish prickles, pale leaves downy underneath, and
small pale-red cinnamon-scented (double) flowers, not showy.

P. spinosissima, Burnet or Scotch Rose. Low, 1° or 2° high,
exceedingly prickly with straight prickles, with 7 to 9 small and roundish
smooth leaflets, and small early flowers, single, double, and white, pink, and
even yellow.

It. sulphurea, the old Yelloav Rose. Tall, with scattered straight
prickles, glaucous or pale leaves, and sulphur-yellow (double) flowers.

It. Eglanteria, Yellow Eglantine Rose. Like a Sweet-Brier, but
lower, 3°- 5° high, with straight prickles ; leaves deep-green (not pale, as in
the last) ; flowers deep yellow, and sometimes variegated with red, either
single or double.

It. Damasoena, Damask Rose. Flowers white or red, single or
double ; the parent of many sorts, such as the Red and White Monthly, York
and Lancaster, Sec. ; distinguished from the next by its greener bark and larger
(curved) prickles, long rejlexed sepals, and elongated hips.

It. eentifolia, Provence, Cabbage, and Hundred-leaved Rose.
Flowers drooping, large, white, blush, or red, mostly full double, and the pet-
als curved inwards ; calyx clammy ; the hips short or roundish ; prickles un-
equal, the larger ones curved.

Var. muscosa, the Moss-Roses of various sorts, have the clammy
glands of the calyx grown out into a moss-like covering.

It. Galliea, French Rose. Flowers red or crimson (sometimes white) ;
of many varieties ; differs from the last by the rigid coriaceous leaflets, erect
flowers, and spherical hips ; less sweet-scented, and petals more astringent.

It. alba, White Rose. Flowers white or with a delicate blush, fragrant ;
sepals pinnate, reflexed, but conniving and remaining on the oblong hip ;
prickles straightish ; leaflets glaucous. "Many common varieties.

It. Indiea, Tea Rose. Came from China, and has furnished endless
sorts ; the leaflets are only 3 or 5, ovate, acuminate, thickish, smooth, and
shining. Noisette Roses' are thought to have originated in a cross between
this and the Musk Rose.

It. semperflorens, Perpetual China or Bengal Rose. Many
sorts, usually with red or crimson flowers, with very little fragrance ; leaflets
as in the last, from which they probably originated, at least in part.

It. Lawrenceana, Fairy Rose. Dwarf, very small-flowered Chinese
Roses, often only 6 inches high, which came from the last.

It. Bailksiee, Banksia Rose. A slender, tall climbing species from
China, cult, in greenhouses, well marked by having no prickles, 3 to 5 lanceo-
late leaflets, and very small (white or buff, violet-scented) flowers, many
together in an umbel-like corymb.

* * Styles cohering in a column which projects out of the calyx-cup.

It. multiflora, Many-flowered Rose. A well-known climbing spe-
cies, from Japan and China, with 5 or 7 soft and somewhat rugose leaflets,
slender scattered prickles, and full corymbs of small flowers, white or pale
red, not sweet-scented. The Boursalt Rose is a more hardy, climbing, red
Rose, said to come from the multi/lora, but probably from a cross with somo
hardy European species.

It. moschata, Musk Rose. Rambling, but hardly climbing, with re-
curved prickles; the leaflets lanceolate, pointed, nearly smooth ; flowers white,
with a yellowish base to the petals, mostly simple, in umbel-like clusters, very
fragrant, especially at evening.

It. sempervirens, Evergreen Rose. Climbing, hardy at the South,
with 'coriaceous bright green leaves, curved prickles, and nearly solitary white
flowers, not double. The Ayrshire Rose is a more hardy variety, the leaves
deciduous.

10. Cotoneaster vulgaris is a low shrub, sparingly planted, with the small
oval leaves white-downy beneath, and small greenish-white flowers ; the fruit
like that of Hawthorns, but including 3 or 4 little seed-like stones.

branches, with short and rounded lobes to the calyx, and large scarlet petals
(single or partly double, also a pale or white variety), appearing a little before
the smooth oval leaves; fruit like a small apple, not eatable. A very orna-
mental shrub.

1. Mesembryanthemum spectabile is the commonest as a house-
plant, with long triquetrous and acute opposite leaves, rather woody stems,
and large red flowers.

M. crystallinum, called Ice-plant, because the oval and wavy alter-
nate leaves and the branches look as if frosted over with white transparent
vesicles ; flowers white, small.

Okder GROSSULACEJ3. Currant Family.

Manual, p. 136. — The cultivated Currants and Gooseberries generally met

with are, —

1. Ribes Grossularia, Garden Gooseberry. Prickly ; leaves obtusely
3-5-lobed ; flowers solitary or in pairs on short pedicels, green ; calyx cam-
panulate; berry large, prickly or smooth.

racemes, and red berries, also a white variety. See Man. p. 137.

R. nigrum, Garden Black Currant, has black berries, like those of
our R. floridum, but the greenish flowers are fewer in the racemes and shorter,
and the bracts minute.

R. aureum, Buffalo or Missouri Currant, from the Far West, with
smooth 3-lobed leaves and a tubular calyx, is planted for its bright-yellow
spicy-scented flowers, appearing in early spring; berries blackish, useless.

2. Eri\3a, Heath. The Heaths (a few of which are from Europe, but a
vast number from the Cape of Good Hope) belong not to common, but only
to choice cultivation : we cannot enumerate the many species which adorn
conservatories.

3. Azalea. Man. p. 257. Besides the wild species, there is one tender and
one hardy exotic.

A. Poutiea. A hardy shrub, with large and clammy yellow flowers, pre-
ceding the pubescent leaves.

A. Indica, Chinese Azalea. A common greenhouse species, with the
flowers (purple, red, rose, white, &c.) later than the leaves; sepals green in-
stead of scale-like, and the stamens commonly 10.

4. Rhododendron, Man. p. 257. Besides our wild ones, Nos. 1 and 2 :
R. punetatum, of the Southern Alleghanies : a much-branched shrub,

with slender and drooping branches, small leaves dotted with rusty globules,
and fine rose-colored flowers, in June.

lxii GARDEN BOTANY.

It. PonticuHl, from Armenia, hardy, but here growing low, with smooth
lance-obovate leaves green on both sides, and large purple flowers.

R. arboreum is the commonest greenhouse species, with obovate-lanceo-
late leaves, either silvery-white or reddish-brown underneath ; and the ovary
of 8 or 10 cells ; flowers large, red, purple, or white.

Order PLUMBAGINACEJE. Leadwort Family.

is used for edging ; the densely tufted leaves narrow linear ; scape 3' to 6'
high ; flowers rose-color, intermixed with scarious bracts.

Order PRIMULACE^I. Primrose Family.

Manual, p. 270. — Several are familiar in gardens or greenhouses, cultivated
for ornament.

Corolla salver-shaped or narrowly funnel-shaped : leaves all radical. 1. PRIMULA.

Filaments beardless : pod not opening round the middle. . . 3. LYSIMACHIA.

Filaments bearded : pod opening round the middle. . . 4. ANAGALLIS.

1. Primula Sinensis, Chinese Primrose. A common house-plant,
pubescent ; leaves 7 - 9-lobed and toothed, rounded, with a cordate base ; umbel
many-flowered, often proliferous ; calyx conical-inflated, nearly as long as
the tube of the large and showy pink or white corolla. Some varieties have
double flowers.

P. veris, Common Primrose. Leaves many in a tuft, wrinkled, pale-
green, denticulate, oblong, with the base contracted into a short-winged
petiole ; corolla straw-yellow, but varying in cultivation into many colors, the
lobes notched at the end. — The Polyanthuses are cultivated varieties. The
English Cowslip is the form with the umbel of flowers raised on a peduncle
above the leaves, the corolla smaller and its limb concave. The true English
Primrose is a variety with a large and flat limb to the corolla, and the com-
mon peduncle wanting, so that the umbel is sessile, and the flowers thus appear
as if radical among the leaves. The Oxlip is between these two.

P. Auricula, Auricula. Leaves obovate-spatulate, sessile, thick, ana
very smooth, pale, often mealy ; umbel raised on a scape ; corolla funnel-
shaped, of many colors, single, double, &c.

2. Cyclamen Europseum, Common Cyclamen, and occasionally one
or two other species, are prized for house-culture; the broad and flat corm sends
up thick and smooth round-cordate leaves, often purple underneath, on slender

stalks, and one-flowered scapes, on the apex of which the graceful flower is
recurved, so that the reflexed divisions of the corolla turn up ; this is rose-
colored or white with a pink base.

3. Lysimachia, Loosestrife. Man. p. 272. Two species are com-
monly met with in gardens : —

L. nummularia, Moneywort. Smooth, creeping over the ground
and rooting, with opposite small orbicular leaves, and solitary axillary light-
yellow flowers. It flourishes in moist places, and is often grown in hanging
pots.

L. vulgaris, English Loosestrife. A stout perennial, more or less
downy, with whorls of ovate-lanceolate leaves and a leafy panicle of deep-
yellow flowers. In old gardens.

4. Anagallis arvensis, Pimpernel. Man. p. 274. The common red
variety is frequent in gardens ; the larger blue one is choicer.

Order GESNEB,IACE.ffi. Gesneria Family.

Tropical plants with 2-lipped or somewhat irregular corollas, didynamous
stamens, a one-celled ovary with two parietal many-seeded placentae, — therefore
botanically like Orobanchacese, Man. p. 279, but with green herbage, and not
parasitic, — and the common cultivated species have the tube of the calyx co-
herent at least with the base of the ovary. Many, and some very showy, plants
of this order are in the conservatories ; the commonest are the following, all
perennials.

1. Gloxinia speciosa. An almost stemless herb, with ovate and crenately
toothed leaves and 1 -flowered scape-like peduncles; the corolla deflexed or hor-
izontal, 2' lonjr, ventiicose, between bell-shaped and funnel-form, gibbous, with
a short and spreading, somewhat unequal, 5-lobed border, pale violet with a
deeper-colored throat, in one variety altogether white.

2. Gesneria zebrina. Stem tall, leafy ; leaves petioled, cordate, velvety,
purple-mottled ; a terminal raceme of showy flowers nodding on erect pedicels ;
corolla tubular-vcutricose, with a small 5-lobed and somewhat 2-lipped border,
glandular, scarlet, with the under side and inside yellow and dark-spotted. —
There are several other species.

3. Aehime'nes longiflora. Stem leafy; flowers in the axils of oblong or
ovate hairy leaves, which they exceed ; tube of the obliquely salver-shaped
corolla over an inch long, narrow, the very flat 5-lobed limb 2' or more broad,
violet-colored above, — also a white variety. Propagates by scaly bulblets
from the root.

Order BIGNONIACEJE. Bignonia Family.

Manual, p. 277. — The following are common ornamental exotics : —

1. Tecoma grandiflora, Great-flowered Trumpet-Creeper. Like
our T. radicans, but less hardy, therefore less climbing, and with a larger but
proportionally shorter orange-red corolla, its proper tube scarcely exceeding
the calyx.

T. Capensis. A bushy greenhouse species, with the flowers crowded,
the red-orange corolla tubular and curved, the stamens exserted.

T. jasminoid.es. A fine greenhouse species, twining, very smooth,
with the leaflets pinnate, lance-ovate, entire, bright green ; corolla white, pink-
purple in the throat

growth more vigorous, and the cylindrical cones hanging at the end of the
branches 4' to 6' long.

8. Larix Europsea, European Larch, is the species commonly planted,
a finer tree and of more rapid growth than the American, its leaves longer,
and its cones larger, 1^' long.

4. Thuja orientalis, Oriental Arbor-Vit^e, is less hardy than ours ;
leaves furrowed down the middle ; cones roundish, the seeds crustaceous and
wingless, wherefore it has been separated as a genus, Biota.

5. Cupressus seiupervirens, Oriental or True Cypress. Not

hardy at the North, in growth like our Red Cedar ; branchlets 4-sided, slen-
der ; cone globose, 1' in diameter, resembling that of Taxodium.

6. 7. Sec the Manual, pp. 424, 425, for the species of these two genera.

8. Taxus baecata, European Yew. Like our Yew botanically, except
that it becomes an erect tree : rarely grows well in this country.

T. Hibemica, Irish Yew, is a marked variety, with branches stiffly
erect, and the leaves equally spreading all round the branchlet instead of
two-ranked.

9. Salisburia adiantifolia, Ginkgo-Tree, of Japan, though hardy,
rarely flowers and does not fruit here. It is of the Yew Family, but of most
remarkable foliage, the leaves being wedge-shaped or fan-shaped, on a slender
petiole, with parallel simply forked veins in the manner of a Fern, the end or
margin erosely toothed or cleft.

10. Cedl'US, Cedar, i.e. True Cedar (what are popularly called Cedars in
this country are Junipers, Cypresses, Arbor- Vita?, &c.) is botanically between
Larch and Pine, but nearer the former, from which it mainly differs in the
leaves being evergreen, therefore more rigid, and pungent, and the cones large,
short, and thick, with broad and thin scales, closely packed. The type is the

ing shoots, unfortunately Little if any more hardy here.

Order CYCADACEJE. Ctcas Family.

1. Cycas revoluta, a plant with the aspect of a Palm, and wrongly called
Saqo Palm, represents this singular order in ottr conservatories, but endures the
winter on the coast of the Southern States. The pistillate plant only is met
with : the large obovate ovules are naked on the margins of reduced pinnate
leaves, where they take the place of leaflets, and grow into red drupe-like
seeds as large as hickory-nuts or larger.

Order ARACEiE. Arum Family.
Manual, p. 426. — The familiar cultivated representative of the order is, —

1. Hicharclia Africana, called Egyptian or ^Ethiopian Oalla, but a
native of ("ape of Good Hope, largely cultivated for its ample sagittate green
leaves and showy white one-leaved spathc, both on long radical stalks, the
latter convolute at its base around tiic cylindrical spadix, which is thickly
covered below with minute pistils, above with yellow anthers.

2. Goloeasia antiquox'um is a kind of huge Arum, raised in greenhouses,
or planted out in moist places in summer, for its immense sagittate-ovate and
peltate leaves, sometimes variegated in color. The 'lowers are uncommon
and insignificant; the spadix enclosed in a greenish spathe, pistillate at the
base, neutral for a small distance, then stuminatc, and the summit slender
and naked.

Order CANNACEjE. Canna or Arrowroot Family.

tuberous-rooted, planted out in summer; the stems sheathed with the bases
of the Urge ohlong pointed leaves, the nerves of which spring from the mid-
rib; flowers red, or yellow towards the base; pod rough or warty, several-
seeded.

2. Maranta zebrina, rarely flowers, hut is a magnificent leaf-plant in con-

and large spiny-pointed and spinulose-margined leaves in a close cluster
at the root : it propagates freely by offsets from the root : when it blossoms
(which it does in its native tropics in 7 or 8 years, but in the colder northern
countries after so many years that it has obtained the name of Century-Plant),
it rapidly sends up a scape as thick as a man's leg, 15 to 30 feet high, bearing
an immense panicle of yellowish-green flowers ; and the plant dies as the pods
ripen their seeds. A variety has the leaves striped with yellowish or white.

1. Zea Mays, Maize, Indian Corn. Culm solid (not hollow as in most
Grasses), terminated by the clustered racemes of staminate flowers (the tassel),
in 2-flowered spikelets ; the pistillate flowers in a dense and many-rowed
spike borne on a short axillary branch, 2 flowers within eacli pair of glumes,
but the lower one neutral, the upper pistillate, with an extremely long style,
the silk.

2. Gynerium ai'genteum, Pampas Grass. A reed-like grass, from
S. America, planted out for ornament, with a large tuft of rijjid lineur and
tapering recurved spreading leaves, several feet in length, the flowering stem
6 to 12 feet high, in autumn bearing an ample silvery-silky panicle of (pistil-
late) flowers.

3. Triticum, Wheat. Produces the troublesome Couch Grass, described
in Man. p. 56'J, and the most valuable cereal or bread plant, viz.

T. vulgare, Common Wheat. Annual [Spring Wheat), or more com
monly by autumn-sowing raised as a sort of biennial (Winter Wheat) ; spike
dense, somewhat four-sided; the spikelets imbricated, turgid, 4 -5-flowered ;
lower palea either awned or merely mucronate : many varieties.

4. Seeale eereale, Rye. Similar to Wheat in structure, but taller and
earlier, with bluish glaucous foliage, the spikelets decidedly two-ranked, only
two-flowered, always long awned ; grain oblong, brown, hairy at the summit.

5. Hordeum, Barley. Differs from Wheat and Rye in having three
spikelets side by side on each joint of the rhachis (although the lateral ones
are sometimes small and sterile), perfecting only one flower : annual.

GARDEN BOTANY. lxxxix

H. VUlgare, Common Barlet. All three spikelets producing a fer-
tile awned tiower and a subulate rudiment, the spike therefore six-rowed or
four-rowed.

H. distiehum, Two-rowed Barley. Lateral spikelets at each joint
sterile and awiiless, the middle one alone fertile and awned.

6. Oryza sativa, Rice. Annual, rough-leaved ; spikelets in an open pani-
cle, one-flowered, very much flattened contrary to the short glumes and hard
and rough paleaj, which are conduplicate ; the latter firmly enclosing the
grain, the lower one awned or awnless. Cult, southward.

7. Stipa pennata, Feather Grass, of Europe, is occasionally raised in
gardens for ornament, the awn of the flower being several inches long and
beautifully plumose, instead of naked, as in the wild species, Man. p. 549.

7. Sorghum, vulgare, Sorgho, Dourra, Guinea Corn, &c. Stem
solid, tall; leaves broadly linear-lanceolate; flowers in an ample terminal
panicle, short-awned or awnless. Broom Corn is a variety of this species,
with long branches to the large and open panicle, which is made into brooms.
Sugar Sorghum is a form of the same with sweeter stems, a northern sub-
stitute for Sugar-Cane. Guinea Corn, or Dourra, the original cereal grain
of tropical Africa, has the panicle densely contracted and the grain larger.

9. Avena sativa, Common Oat. Annual, with a loose panicle of very
large and drooping two-flowered spikelets ; palese enclosing the grain, that of
one flower with a long and twisted awn on the back, the other awnless.

10. Briza maxima, Great Quaking-Grass. Annual, resembles D. media
of Man. p. 565, but the spikelets are larger, over half an inch long, and very
turgid : occasionally cultivated in gardens for ornament.

Dr. Engelmann's surmise prove correct (as is most likely), this species will bear
the name of A. lanuginosa, Decaisne.

(as ascertained by Prof. H. G. Clark), and in Lilium (as shown by Dr. Chap-
man), Hemerocallis, &c. Other distinctions having also given way, it becomes
apparent that Srnilacese and Melanthaceas will hereafter be merged in the great
order Liliaceas.

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

traordinary irritability of its leaves, closing forcibly at the touch, — is a native
of the sandy savannas of the eastern part of North Carolina. It differs in sev-
eral respects from the character of the order given above; the stamens being 15,
the styles united into one, and the seeds all at the base of the pod.

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.

* In certain families, such as Ericaceae, &c. the petals in some genera are nearly or quite
separate. In CompositaD and some others, the calyx is mostly reduced to a p;ippus, or to scales,
or a mere border, or even to nothing more than a covering of the surface of the ovary. The

fixed to the volume provides for all those anomalies, and will lead the student to too order

the ovary, the limb cup-shaped, without a 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 Sn//ao>,
to thirst, probably because the united cup-shaped bases of the leaves in some
species hold water.)

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

D. Full6ncm, the cultivated Fuller's Teasel, which has a shorter invo-
lucre, and stiff chaff to the heads, with hooked points, — used for raising a nap
upon woollen cloth.

Order 59. COMPOSITE. (Composite Family.)

Flowers in a close head (the compound flower of the older botanists), upon
a common receptacle, surrounded by an involucre, with 5 (rarely 4) stametis
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, monoecious or dioecious 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 Pluenogamous plants,
divided by the corolla into three suborders, only two of which are repre-
sented in the Northern United States.

Suborder L TUBULIFLOR^J.

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 Tuhuliflorcr,
taken from the styles, require a magnif'ying-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.)

Order 74. SCROPHULARIACEiE. (Figwort Family.)

Chiefly herbs, icilh 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 placentas 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 arc not differ-
ent enough to be classed as suborders*) ; — to which an anomalous genus
(Gelsemium) is appended : but that belongs to Loganiete, p. 169.

* The technical distinction between the so-called suborders is principally in the testivation
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
species of Pen'stemon.

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 b« the case in Gerardia also, by Mr. Jacob Staufler, of Mouut Joy, Pennsylvania

brous sepals. Stamens 2-5, mostly 3r Stigmas 3. Fruit an ovato and often
rather fleshy 1-sceded utricle, which does not open or bursts irregularly. Other-
wise much as in Amarantus. (Name said by the author to mean "well shut,"
probably formed illegitimately of ev, very, and oXos, whole or entire.)

ovate or oval, long-petioled ; axillary spikes or heads dense, much shorter than
the petioles, the terminal elongated ; sepals 3, much longer than the bracts, rather

370 AMARANTAOE.E. (AMARANTH FAMILY.)

1. M. fainairisciiiia. (Amarantus tamariscinus, Nutt., & cd. 1. A.

altissiinus & 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 (i'-J' in diameter) in the axils of the leaves; the stems often low
and spreading or decumbent. — A very variable plant, as to inflorescence, height
(l°-6° high), the size and shape of the leaves (l'-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 Miehaux'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 ripe fruit, I adopt Nuttall's specific name.

4. ACNIDA, L. Watek-Hemp.

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

formed of a privative and Kvidrj, a nettle.)

1. A. CiiBiEBi^JtiiRia, L. Leaves elongated-lanceolate or ovate-lanceolate,
long-petioled ; fruit globular (li" — 2'' long), much exceeding the pointless
bracts. ■; < - — Salt-marshes on the coast, Massachusetts to Virginia and south-
ward. Aug. -Oct. — Plant 3° -6° high. — Probably the only species ; for A.
rusocarpa, Michx., is certainly to be divided between this and Montelia tamaris-
cina ; and A. tuberculata, Moquin, is likely to be one or the other.

5. I RE SINE, P. Browne. Iresine.

Flowers mostly polygamous or dioecious, 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 elpeaiavr), a branch entwined with fillets of wool borne in pro-
cessions at festivals.)

leaves ovate-lanceolate ; panicles narrow, naked ; bracts and calyx silvery-white,
the latter woolly at the base. ® — Dry banks, Ohio, Kentucky, and south-

lanceolate, silky-downy beneath ; spikelets crowded into an interrupted spike ;
calyx very woolly. (X— Illinois, in Mason and Cass Counties, Mead, T. J. j
E. Hall, <bs. Western "Wisconsin. Aug. — Apparently indigenous : but else-
where it is only found much farther south.

Order 92. POLYGON ACE^. (Buckwheat Family.)

Herbs, with alternate leaves, furnished with stipules in the form of sheaths
(ochreas) above the swollen joints of the stem ; the flowers mostly perfect,

stigmas, and a single erect orlhotropous seed. Embryo curved or straio-ht-
ish, on the outside of the albumen, or rarely in its centre; tin' 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. Leai es usually
entire. (The watery juice often acrid, sometimes agreeably acid, as in

with longer white hair. Sterile catkins like the last ; but the fertile shorter and
broader, the pods (at length merely downy) spreading and showing the stalks.

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. Hudsunica : he, however, found it " only on the banks of the Hudson
River, above Albany." Lastly, it was described as P. betulijblia 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 Hobokcn, New Jersey.

P. dilatata, Ait., the well-known pyramidal Lombardt Poplar, has
Deen extensively introduced as an ornamental tree, and is found in the vicinity
of all old settlements.

P. Alba, L., the Abele or White Poplar of the Old World, is occasion-

cous, the sheatlis deciduous ; cones narrow, cylindrical, nodding, a little curved
(4' -6' long). — Cool and damp woods ; common northward, extending south-
ward in the Alleghanies, but rare in those of Virginia. — The White Pine (called
in England Weymouth Pine) is our tallest tree, often 120° -160° in a single
straight column in primitive forests, and is invaluable for its soft and light
white or yellowish wood, which in large trunks is nearly free from resin.

2. ABIES, Tourn. Spkuce. Fir.

lets. Scales of the strobiles thin and flat, not at all thickened at the apex, nor
with a prickly point. Seeds with a persistent wing. — Leaves all foliaceous and
scattered, short, frequently 2-ranked. Otherwise nearly as in Pinus. (The
classical Latin name.)

§ 1 . Cones erect, lateral ; the scales and the more or less projecting bracts falling front
the axis at maturity : sterile catkins clustered : anther-cells opening by a transverse
laceration : leaves flat, becoming 2-ranked, whitened underneath, obtuse or notched
at the apex. (Abies, Pliny, $*c. Picea, L., Don, Loudon, not of Link.)

I. A. balss'i sm-a, Marshall. (Balsam Fir.) Leaves narrowly linear ;

cones cylindrical, large, violet-colored ; the bracts obovate, serrulate, tipped with an
abrupt slender point, slightly projecting, oppressed. — Cold damp woods and
swamps, New England to Penn., Wisconsin, and northward. — A slender tree,
of little value as timber, when young very handsome, but short-lived. Leaves
1' or less in length, narrower and lighter green above than those of the European
Silver Fir ; the cones 3' -4' long, 1' broad, the scales very broad and rounded.
Also called Canada Balsam or Balm-of-Gilead Fir. The well-known Canada
balsam is drawn from blisters in the bark of this and the next species.

the scales with a thin and wavy or eroded edge. — Swamps and cold mountain
woods, New England to Wisconsin and northward, and southward along the
mountains. — A common variety in New England has lighter-colored or glau-
cous-green leaves, rather more slender and loosely spreading : it is often mis-
taken for the White Spruce. — A. rubra is a northern form of A nigra.

5. A. a!S>a, Michx. (White Spruce.) Leaves pale or glaucous ; cones
cylindrical, about 2' long, pale, tbe scales with an entire edge ; a handsomer

than No. 4, more northern, in aspect more like a Balsam Fir. — Northern

rack. Hackmatack.) Leaves almost thread-form; cones ovoid, of few
rounded scales. (P. pendula, Ait.) — Swamps, New England to Penn. and
Wisconsin, and (chiefly) northward. — A slender tree, with heavy, close-grained
wood, and slender horizontal branches, more slender and usually shorter leaves
than the Em opean Larch ; — which is a handsomer tree, and has the scales of
its larger cones arranged in the order ^, while those of the American are only §.

— Tbe Red Larch (P. microcarpa, Lambert) appears to be only a Northern
variety.

1. NAIAS, L. Naiad.

Flowers dioecious (or sometimes monoecious), axillary, solitary and sessile ;
the sterile consisting of a single stamen enclosed in a little membranous spathe :
anther at first nearly sessile, the filament at length elongated. Fertile flowers
consisting of a single ovary tapering into a short style : stigmas 2-4, awl-
shaped : ovule erect, anatropous. Fruit a little seed-like nutlet, enclosed in a
loose and separable membranous epicarp. Embryo straight, the radicular end
downwards. — Slender branching herbs, growing entirely under water, with
opposite linear leaves, somewhat crowthfcl into whorls, sessile and dilated at tho
base. Flowers very small, solitary, but often clustered with the branch-leaves
in the axils. (Nai'dy, water-nymph ; an ill-chosen name for these insignificant
water-weeds; from their place of growth.)

1 . N. flexiliS, Rostk. Leaves membranaceous, spreading, very narrowly
linear, entire, or sparingly very minutely denticulate (under a lens) ; stigmas
usually 3-4. (N. Canadensis, Michx. Caulinia flexilis, Willd.) — Ponds and
slow streams ; common. July -Sept. (Eu.)

N. minor (Caulinia fragilis, Willd.), with the more rigid and recurved frag-
ile leaves rather strongly toothed, is not identified in this countiy.

2. ZANNICI1EL.LIA, Micheli. Horned Pondweed.

Flowers monoecious, sessile, naked, usually both kinds from the same axil :
the sterile consisting of a single stamen, with a slender filament bearing a 2 - 4-
ccllcd 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.
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 lienor of Zannichelli, a Venetian botanist.)

1. Z. palustris, 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. peduncuiAta, both
the cluster and the separate fruits evidently pedunclcd. — Ponds and slow
streams; rather rare. July. (Eu.)

3. ZOSTERA, L. Grass-wrack. Eel-grass.

Flowers monoecious ; the two kinds naked and sessile and alternately arranged
in two rows on the midrib of one side of a linear leaf-like spadix, which is hid-
den in a long and sheath-like base of a leaf (spathe) ; the sterile flowers consist-

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 rootstock, sheathed by the
bases of the very long and linear, obtuse, entire, grass-like, ribbon-shaped leaves
(whence the name, from ^coa-rrjp, 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. RIJPPIA, L. Ditch-gkass.

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 oblicpiely-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 time of expansion.
(Dedicated to Ruppius, a German botanical author of the early part of the 18th
century. )

1. R. maritima, L. Leaves linear-capillary ; nut ovate, obliquely
erect; fruiting peduncles capillary (h'-V long). — Shallow bays, along the
whole coast : chiefly a narrowly leaved variety with strongly pointed fruit, ap-
proaching R. rostellita, Koch. June -Aug. (Eu.)

5. POTAIOGETON, Tourn. Poxdweed.

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 drape-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 pelhuid leaves, which are usually alternate or imper-
fectly opposite ; the upper sometimes dilated, of a firmer texture, and floating.
Stipules membranous, more or less united and sheathing. Spikes sheathed
by the stipules in the bud, raised on a peduncle to the surface of the water.

NAIADACE.E. (PONDWEED FAMILY.) 435

Var. Niagai'ensiS (P. Niagarensis, TucJcerm.), from the brink of the cat-
aract of Niagara, appears likely to be a larger-leaved and more rigid state of
this species; the stipules more conspicuous, the leaves sometimes 1^" wide.

7. P. COHJpreSSliS, L. ex Fries. Stem very flat, almost as wide as the
narrowly linear abruptly pointed leaves; spikes cylindrical, 10-15-flowered ; fruit

Z-many-nerved, and with cross veinlets : stems more or less branched.

8. P. pcrfi>liatu§, L. Leaves clasping by a heart-shaped base, ovate or
ovate-lanceolate, sometimes round-ovate, obtuse; spikes rather few-flowered ; fruit
rounded on the back. — Ponds and rivers; common. — Leaves l'-2' long, flat ;
or, in the longer and ovate-lanceolate American forms, inclined to be acute and
more or less wavy or crisped. (Eu.) See Addend.

9. P. fii'celdllg'IlS, Wulf. Leaves elongated-oblong, obtuse at lioth ends,
half-clasping by the sessile base ; peduncles often much elongated (in deep water
6'- 12' long) ; spike cylindrical, many-flowered ; fruit strongly heeled on the back
when dry. — Rivers and ponds, New England to Wisconsin and northward. —
Stipules wingless. Leaves 1' or less wide, 2' -7' long. (Eu.)

* * # Leaves not clasping, mostly of 2 sorts ; the immersed ones acute at the l>ase or
tapering into a petiole, thin and pellucid, many-nerved and reticulated by cross-vein-
lets, the floating ones somewhat coriaceous and long-petioled : stems simple or spar-
ingly branched.

10. P. lliccns, L. Immersed leaves ample (3' -9' long), varying from
oblong-oval to broadly lanceolate, undulate, somewhat petioled; the united stip-
ules 2-winged or keeled on the back ; peduncle thickened, especially upwards ; spike
elongated, dense ; fruit 1 - 3-keeled on the back. — The proper P. lucens usually
wants the floating leaves, and is common in deep water. (Eu.)

Var. ? fluif ailS. 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., &c. ; and here I would
refer P. pulcher ? and P. amplifolins, Tuckerm. P. rufescens, Schroder, 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 been
able to limit them. (Eu.)

11. P. u:\taaas, L. Immersed leaves narrowly lanceolate or linear and
mostly long petioled ; the thin blade early decaying, sometimes wanting ; floating
leaves long-petioled, elliptical or ovate-oblong, sometimes slightly heart-shaped

at the base (l£'-4' long, the petiole 4' -12' long); stipules not winged nor
ridged; peduncle not thickened; fruit obtuse on the back when fresh. (P. lonchites,
Tuckerm.) — P. oblongus, Viv., is a small-fruited form. — Ponds and slow
streams; common. (Eu.)

12. P. hetcropliyllus, Schreber. Stem slender, branching ; immersed
leaves lanceolate or linear and sessile, or only the upper pctioled ; floating leaves
elliptical, varying to oblong-linear, thinnish (l'-2' long), on filiform petioles ;
united stipules 2-ribbed on the back; peduncle often thickened upwards; fruit slightly
keeled when dry (one half smaller than in the preceding). (P. gramineus, L.
in part, Fries, $-c. P. Claytonii, Tuckerm.) — In shallow pools and ditches, as
well as streams ; common. (Eu.)

P. crisp us, 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. See Addend.

P. densds 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.

the fertile 2-leaved, with a single short-pedicelled flower. Calyx 3-parted or
cleft ; sepals oblong-oval. Petals 3, oblong-linear. Filaments entirely united
in a central solid column, bearing 6-12 linear anthers at unequal heights : there
are 3-6 awl-shaped rudiments of stamens in the fertile flowers. Ovary 6-9-
celled, with as many placenta? in the axis, forming an ovoid many-seeded berry

2. ANACHABIS, Rich. (Ud6ra, Nutt.) Water-weed.

Flowers polygamo-dioecious, solitary and sessile from a sessile and tubular
2-cleft axillary spathc. 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, oral. 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 imperfect ones, sometimes with oblong almost sessile anthers.
Ovary 1-celled, with 3 parietal placentae, each bearing a few orthotropous ovules ;
the capillary style coherent with the tube of the perianth : stigmas 3, 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, whorlcd 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 adapts, without charms, being
rather homely water-weeds.)

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

3. VALLIS1VEBIA, Micheli. Tape-grass. Eel-grass.

Flowers strictly dioecious : the sterile numerous and crowded in a head on a
conical receptacle, enclosed in an ovate at length 3-valved. spathc 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-cellcd 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 scattered over the walls, 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.)

Order 119. ORCHIDACE^E. (Orchis Family.;

Herbs, distinguished by their irregular flowers, G-merous perianth adherent
to the 1-celled ovary with 3 parietal placental, 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 Up. 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 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 3 divisions in-

"In 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-
Bi- tance to the student to give a leading name to the principal groups, aud in some cases have
a lopted 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 Psyllophora?, 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
enumeration 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 upou
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 aud alterations

leaf-like or scale-like bracts ; commonly with thin membranaceous sheaths at
the base which enclose more or less of the stalks of the spikes. Leaves grassy,

cation ; derived by some from careo, to want, the upper spikes being mostly
sterile ; and by others from K€ipa>, to cut, on account of the sharp leaves.)

534 CYPETCACE.E. (SEDGE FAMILY.)

Distinguished from the next by the shorter fertile spikes, on rough stalks, and
by tiie more oblong perigynium, many-nerved at the base. (En.)

127. C uioaiifc, Tuckerman. Sterile spikes 3, rarely 2 or 4; fertile spikes
mostly 2, rarely 3 or solitary, long-cylindrical, remote, on smooth stalks, the lowest
often nodding and loosely flowered ; perigynia roundish-ovoid, about 10-nerved,
with a short tapering beak terminating in an oblique orifice, much longer and
broader than the taper-pointed azvnless scale ; culm slender, sharply angled and
rough ; leaves and bracts green, longer than the culm. (C. bullata, var. cylin-
dracca, & C. vesicaria, var. cylindraeea, Dew.) — Bogs, New England to Ken-

utriculata, Boott.) — In swamps; common northward, and from Arctic Ameri-
ca 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-
rate it specifically. (Eu.)

129. C. cylilBdl'icn, Sdrw. Sterile spikes about 2; fertile spikes 2-3,
commonly 3, oblong or cylindrical, stout, somewhat approximate, on rough stalks,

much longer and broader than the ovate pointed or rough-awned scale ; bracts
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,
W. New York to Kentucky, and northward. — Differs from the next principally
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
smooth stalks; perigynia spreading, ovoid, tapering into a long-cylindrical rough

bracts and leaves narrow, about the length of the smooth or roughish culm.
(C. cylindrica, Tuckerman, Ton: N. Y. Fl. (excl. syn.), not of Schiv.) — 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-soreading fruit; its beak minutely (but
distinctly) serrulate. See Addend.

cleft at the membranaceous orifice, a little longer than the lanceolate light-colored
or white scale. (C. Sprengelii, Dew.) — Shady rocks, N. New England to Wis-
consin, and northward. — Though agreeing with the species of this section in the
numerous staminate spikes and the long-beaked fruit, this plant is perhaps as
nearly allied to No. 97.

Order 134. GRAMINEiE. (Grass Family.)

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 brads : the outer pair
(glumes proper, calyx, L.) subtending the spikelet of one or several flow-
ers ; the inner pair (palece, outer perianth, B. Br.) enclosing each partic-
ular flower, -which is usually furnished with 2 or 3 minute hypogynous
scales (squamulas, Juss., corolla, Micheli, hdicukc, Beauv.). Stamens 1-6,
commonly 3 : anthers versatile, 2-eelled, 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. — Boots 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. See Plates I. to YILT.

(A genus, according to its author, most allied to Deschampsia (Aira), from
which it differs in its entire and awnless paleas, — an alliance strengthened by
the following remarkable new species which I venture to place in it ; — leaving
the genus among the Festucinea; 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,

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

woo! when young; sterile fronds smooth when full grown, the lanceolate pinnce
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

of organs, contained in indehiscent or irregidarly bursting involucres (sporo-
carps) : — here represented bv only two genera ; one of them, Isoetes,

above with the dilated imbricated bases of the elongated terete awl-shaped or
Btalk-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 powdeiy
grains (analogous to the spores of Lycopodium) ; the exterior filled with larger
spherical-cpiadrangular spores (oophoridia), at first cohering in fours, their crus-
taceous integument marked by 3 radiant lines. (Name composed olla-os, equal,

single diaphanous membrane, ovoid ; the smaller kind opening transversely all
round, containing several roundish-angular antheridia ? pcltately 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,

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.

musci. (mosses.) 607

Class 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.

Order 139. MUSCI. (Mosses.*)

Low, tufted plants, always with a stem and distinct (sessile) leaves, pro-
ducing spore-cases which open by a terminal lid (except in Nos. 1 -4), and
contain simple spores alone. Reproductive organs of two kinds : f 1. The
sterile (male) flower, consisting of numerous (4-20) minute cylindrical
saes (anther id ia) 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 1 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, ciliolce. An elastic
ring of cells (annulus) lies between the rim of the capsule and operculum.
The powdery particles filling the capsule are spares 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 cucidliform, if not, it is
mitre-shaped or mitrifonn. Intermixed with the reproductive organs are
cellular jointed filaments (paraphyses). The leaves surrounding the an-
theridia are called the perujonial leaves ; those around the archegonium or
pedicel, the perichcetial leaves.

* By William S. Sullitant, Esq.

t That the antheridium of Mosses bears the same relation to the archegonium which the
Hither does to the pistil in Phasnogamous plants, cannot now reasonably be doubted, although
perhaps not established by direct proof. Fruit is never produced wtthf ut the co-operation of
both these organs.

Order 140. HEPATIC JE. (Liverworts.*)

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 frondose, 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
(amphigastria) on the under side of the stem. Reproductive organs of two
kinds, viz. antheridia and pislillidia, 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-
lar forms. The antheridia in the foliaceous species are situated ill 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.

FASQTJELLE'S FRENCH SERIES.

Messieurs Masset and Villeplait, Professors of the French

Language in New York, write ; — " "We consider ' Fasquelle's French Course' a valu-
able'and appropriate addition to the different grammars of the French Language.
The arrangement adopted is systematic, and so simplified as greatly to facilitate the
progress of the student."

Prof. Alphonse Brunner, of Cincinnati, says: — "Having

been a teacher of my vernacular tongue— the French— for ten years, in my opinion, it
is the best book yet prepared. I recommend it as superior to the old theoretical
grammars.11

Prof. J. B. Torricelli, of Dartmouth College, writes : — " I

tiie pleasure in recommending to the teacher as well as to the private student,
' Fasquelle's New Method,' as the best yet published. Its adoption in our Colleges
and Seminaries has given entire satisfaction. Mr. Fasquelle deserves the thanks of
all lovers of the French language."

Rev. Charles Collins, D.D., President of Dickinson College,

p„. : "We have introduced Fasquelle's French Series with very decided approbation."

Prof. Everett, of Bowdoin College, Me.: — "Fasquelle's

French Course is decidedly the best grammar ever published."

Edward North, A.M., Professor of Languages, Hamilton

College, N. Y. : "Fasquelle's French Course I continue to use, and to like. It is

worthy of its immense popularity."

Rev. George B. Jewett, late Professor of Modern Lan-
guages, Amherst College:— "I have examined Fasquelle's French Series with mu-u
pleasure and satisfaction. They form an admirable series."

Prof. Charles Gobelle, Professor of Modern Languages,

Newbury Female Collegiate Institute, Vt. :— " I have been using Fasquelle's French
Course during the past two years in one of the best schools in New England. It "1
the very beat book I know of for instruction in the French language."

Prof. T. Peyre-Ferry, Teacher of French in the New Jersey

Normal School, Trenton :— " Fasquelle's Course is the best work ever published of the
bind. It enables the pupil to acquire a practical knowledge of the French language.''

Rev. G. W. Quereau, A.M., Principal of Conference Seroi-

narv, Greenwich, R. I. : — " Fasquelle's Course is our standard test-book in French.
We use it because we think it best. I speak with some confidence, and am satisfied
I hat it is decidedly superior to any other book of the kind."

James B. Angell, A.M., Professor of Modern Languages in

Brown University, writes :—" I gladly testify to the excellence of Fasquelle's French
Course, which I have used in my classes for three years."

l\ N. Legendre, Professor of French, New Haven, Cl.,

,ays: — " Never has a work come under my notice, that blends so happily and har-
moniously the great rival elements of the language. My pupils study it with pleasure."

E. J. P. Wohrange, Professor of Modern Languages in the

IS 7. Central College, writes : — '"Fasquelle's Course' is at, the same time original
tad complete in itself, superseding all systems now in use."

The N. Y. Daily Times says: — " Prof. F. is somewhat of

»a enthusiast as to his method of teaching, and being blessed with as much sense as
experience, makes a better arranged text-book, and grades the difficulties more hap
jaly than any other modern teacher."

The Philadelphia Daily News speaks of the " Napoleon," as

" a very concise and interesting French history which, edited m it is by Prof. Fas-
quelle, can not fail to prove a very popular school-book. The narrative is in Dumas
most brilliant and attractive style."

The N. Y. Independent says of the " Napoleon" :— " It com

bines the advantages of a stirring biography to invite the student, a good French
style and grammatical and critical exercises and annotationa"

not hesitate to say, that ' Fasquelle's French Course' is superior to any other Frenc
Grammar I have met with, for teaching French to those whose mother-tongue

It treats. For the true interest of all engaged in the study of the spoken French, ws

FASQUELLE'S
FRENCH SERIES.

By LOUIS FASQUELLE, LL.D.,

Professor of Modern Languages in the University of Michigan

CHARACTERISTIC FEATURES.

1. The plan of this popular Series embraces a combinatioi
of the two rival systems ; the Oral, adopted by Ollendorff,
Robertson, Manesca, and others, with the old Classical, or
Grammatical System. One of its principal features is a con-
stant comparison of the construction of the French and English
Languages.

2. Another important feature consists in the facility with
which the instructor or student can elect in the course of stud)
the practice and theory combined, or as much or as little of
either as he deems proper.

3. The " Course" commences with a complete though short
treatise on pronunciation, presenting the power of each letter
as initial, medial, or final, and also its sound when final and
carried to the next word, in reading or speaking.

4. The changes in the words are presented in the most simple
manner, and copiously exemplified by conversational phrases.

5. The rules of composition, grammatical and idiomatical,
are introduced gradually, so as not to offer too many difficulties
at one time.

G. The verbs are grouped by tenses, and comparisons insti-
tuted, showing their resemblance or difference of termination
in the different conjugations.

V. The second, or theoretical part, offers, in a condensed
form, a solution of the principal difficulties of the language.

8. The Rules are deduced from the best authorities, and illus-
traded by short extracts from the best French ivriters.

9. A treatise on gender is given, containing rules for determin-
ing gender by the meaning of words, and also by the termination,

10. The Irregular, Defective, and Peculiar verbs are pre-
sented in an Alphabetical Table, producing a Complete Dic-
tionary of these verbs.
