WHEN this revised Edition was commenced, it was contemplated —
with the aid of kind Friends — to insert a brief description of all
the indigenous species of the Vegetable Kingdom which had been
detected in our County, — together with such introduced plants as
had become naturalized, or were CULTIVATED for useful purposes.
It soon became apparent, however, that the lower Orders (especially
the Fungi) were so multitudinous, as well as obscure, that it would
require more time to accomplish the undertaking, than /, at least,
had any right to reckon upon. It was found, also, that to include
the whole, would render the work inconveniently voluminous. A
descriptive enumeration of the Fungi, alone, would make a respect-
able volume. It was therefore concluded to omit all below the
Lichens, — and leave that portion of our Botany to the future enter-
prise of our Chester County Naturalists.

For the account of our Mosses and Hepaticae, I am indebted to
the researches, and kind attention, of THOMAS P. JAMES, Esq. an
enthusiastic Bryologist of Philadelphia. The Lichens have been
collected and determined by Dr. EZRA MICHENER, of this County, —
a Naturalist from whose acumen, diligence, and indomitable per-
severance, we may fairly expect as thorough an exploration of every
department of our Cryptogamy, as the active duties of his Profes-
sion, and the life-time of an Individual, will permit. I am gratified,
moreover, in knowing that a few zealous and faithful Lovers of
Nature are engaged with him, as Collaborators, in the laudable
attempt to prepare a comprehensive Natural History of the County
of Chester. — w. D.

DISCOUBSB I.
Definition of Botany. Inducements to the Study.

HAVING prepared a new Edition of the Chester County Flora, —
partly for the purpose of including those plants "which have been
detected in the County since the preceding one was published — but
chiefly for the sake of presenting the work in a form somewhat less
diffuse in its details, as well as more congenial in its arrangement
with the present state of the Science, — I thought it might be accept-
able to the youthful Cultivators of Botany, in our venerable Baili-
wick, to premise some general observations touching the subject to
which the volume is devoted.

This I propose to do, in a few brief and familiar Discourses ;
such, in substance, as I have been in the habit of employing,
orally, when aiding the researches of the Pupils in some of the
West-Chester Seminaries.

As in all attempts to impart or acquire information, it is most
advantageous and satisfactory to begin at the beginning, — we may as
well commence by a definition of the Science, to which we propose
to direct our attention. It derives its name from the Greek word
Botdne — meaning an Herb, — and may be briefly defined as "the
natural history of the Vegetable Kingdom ;" or, to be somewhat
more explicit, it is that Science which has for its object a knowledge
of the structure, functions, and characters of Plants — together with a
just comprehension of those general affinities, and peculiar features,
by which they may be grouped into kindred families, — and yet be
distinguishable, among themselves, into well-marked Genera, and
Species.

A very natural preliminary inquiry, on the part of a Pupil
engaging in the study of Botany — or, indeed, in any other study —
would be respecting the utility, or value, of such an attainment;
and therefore — in order to encourage the young Beginner — it may
be well to hint at some of the inducements to the undertaking.
These may be considered in reference to mental discipline, intel-
lectual gratification, and practical usefulness. It is impossible for

any one, endowed with the common attributes of humanity, to
avoid being something of a Naturalist. One of the earliest indica-
tions of Intellect, consists in the perception, and discrimination, of
the beings and objects subjected to its cognizance. In proportion
as the mind is expanded, and its faculties disciplined, so are its
powers of discrimination augmented. Natural Science — or that
knowledge which enables us to ascertain, to distinguish, and to
arrange, or classify created beings — is emphatically a science of
observation; and no study has a happier tendency to induce habits
of attention, and accuracy in noticing the characteristic features of
objects. No one is less likely to be misled by vulgar prejudices, or
to be made the dupe of imposture, than the careful observer, and
intelligent student, of Nature. Habitual scrutiny renders him
acute in detecting error, and discovering truth, — while it makes
him cautious in receiving marvellous statements unsupported by
credible testimony.

While his faculties are thus improved by a salutary discipline,
his taste is no less gratified by the pleasures of the study : — and, of
all the inanimate products of creation, there is none more agreeable
to contemplate, than those which constitute the Vegetable Kingdom.
Destined, by the wisdom of a bountiful Providence, for the susten-
ance of a higher order of creatures, — they have, at the same time,
teen admirably adapted to the purpose of adorning the surface of
the earth, and charging with fragrance the atmosphere which
surrounds it. Occupying an intermediate position, between minerals
and animals, they afford us the means of investigating the wonders
of organic life, without the infliction of torture, or the necessity of
witnessing the sufferings which attend such researches in sensitive
beings. Hence, the study of the vegetable creation has ever been
a favorite pursuit with gentle minds. There is a calm delight in the
contemplation of Plants and Flowers, which is never felt — and can
never be appreciated — by those who find their chief gratification in
the turmoils and commotions of the animal world. The disposition
of man derives much of its character from association, and external
impressions; and it is, doubtless, partly owing to the bland in-
fluences of a rural life, that enlightened agricultural communities are
less prone to those cruel excesses, which so often disturb the arti-
ficial and struggling society of crowded cities. If such be the
tranquilizing tendency of a simple residence among the Vegetable
tribes, — how propitious to the growth of the gentler virtues must
be the pursuits of the Botanist, who may be said — almost without a
figure— to hold daily converse with some of the loveliest works of

the Creator, — and to regard with something like the pleasure of a
friendly recognition, every Plant -which he has successfully in-
vestigated!*

We know, indeed, that those groveling mortals who consider
nothing as valuable, but mere tangible wealth, are apt to regard the
researches of the Naturalist as useless and frivolous,— just as gross,
uncultivated minds suppose all pleasures to consist in sensual grati-
fications, and have no conception of such a thing as intellectual
enjoyment. It is the besetting infirmity of sordid natures, to mis-
take the instrument for the object ; to limit the aim, and confine the
affections, to the means of enhancing our character, as rational
beings — instead of employing those means for the attainment of a
nobler end. But, is it true, that the studies of the Naturalist are
useless and frivolous ? On the contrary, the most bigoted Utilitarian —
on a moment's reflection — will be forced to admit, that they are
fraught with results of daily, and high practical value, in many of
the most important pursuits. To the Agriculturist, the Gardener,
the Physician, and the Artist, a correct — and even scientific —
knowledge of the Vegetable Kingdom is, to a certain extent, indis-
pensable : — for, a scientific knowledge of plants merely implies an
acquaintance with their true character and properties, — and that,
every person whose business is with plants, is bound in honesty
and good faith — as well as by the requirements of self-interest — to
possess. Such knowledge is, of course, to be best obtained by
means of the most skillful, systematic, and facile method of in-
vestigation; or, in other words, by the help of a truly scientific
arrangement.

* No one ever heard a true lover of Botany complain of taedium vitae, or of a
want of pleasant employment for his leisure hours. His pursuits, it is true, do
not produce that vehement excitement which attends the scrambling rivalry of
political aspirants, and is so seductive to the eager fancies of the crafty and ambi-
tious ; but the gratifications resulting from their culture — being founded on a
consciousness of their value to our fellow creatures, as well as to ourselves — are
of the most precious and enduring character,— and are, moreover, wholly inde-
pendent of vulgar taste or caprice. [See Sir H. DAVY'S Consolations in Travel.]

The attractions of Botanical Science are truthfully and appropriately alluded
to, in the following extract of a Letter from the late Sir JAMES EDWARD SMITH to
the Rev. Dr. MUHLENBERG,— dated London, March 6, 1793 :— " You cannot be more
enthusiastically fond of Botany than I am; and your letter promises me a fresh
instance, in addition to many already experienced, that this study— charming in
itself— is still more valuable as a key to the intercourse of the most amiable
minds. To Botany I owe friendships and connexions I else could have had no
chance of forming; and your Letter, overflowing with the milk of human kind-
ness, and with the amiable modesty of real merit, promises mo one which it will
be my most anxious care and ambition to deserve."

Viii PRELIMINARY DISCOURSES.

The successful culture of Vegetable Products, requires a know-
ledge of the character and habits of the Plants which yield them ;
and that knowledge — so far as it is possessed and applied — is neither
more nor less than practical Botany. He who is acquainted with
the greatest number, and best understands how to multiply the
most valuable, is at once the best Botanist, and the most accom-
plished Agriculturist and Gardener.

Is it not desirable, then, that we should extend our knowledge of
the useful Plants, — and learn to estimate correctly, their true and
relative values ? Is it not necessary, also, that we should have a
competent knowledge of the pernicious and worthless Plants ? But,
to accomplish this, is to make a respectable progress in the Science
of Botany. Hence I contend, that a certain portion of Botanical
knowledge is indispensable to the Farmer who aspires to excellence
in his profession, — and who would aid in elevating that profession
to the rank which it is intitled to hold, among human pursuits. —
It is not necessary that he should prosecute the study in all its
extent ; for that would be the business of a life-time : But he ought
to make himself acquainted with the Vegetation of the region, or
district, in which he resides,— and he should understand well the
character of all those plants which immediately concern him, as an
Agriculturist. This is a duty by no means so difficult as is generally
supposed: And with the aid now afforded by elementary and
systematic writers on the subject, the attainment is rendered as
agreeably interesting, to an intelligent mind, as it is profitable in
its practical -results. The man who does not know the more im-
portant plants by which he is surrounded — whose eye has not learnt
to discriminate their characters, — is deficient in one of the primary
qualifications of an enlightened cultivator of the •soil. In truth, it
is mortifying to see a good practical Farmer, or Gardener, ignorant
of some of the very plants which it most behoves him to know, —
wasting his time, and his energies, in mis-directed ^efforts to protect
himself from the vegetable pests which invade his grounds. Many
of our farms are already over-run with worthless weeds, which are
extremely difficult to subdue; -and we are menaced with the inroads
of others still more annoying and pernicious : Yet there are but
few of our Agriculturists who fire able to identify these invaders,
when they make their appearance, — or who seem to be aware of the
importance of prompt and vigorous measures for their extirpation.*

* I have seen an excellent old Farmer zealously waging war upon the fetid
Chamomile (Maruta. Cotula, DC.), under the mistaken belief that he was contend-
ing against that troublesome nuisance, the Ox-eye Daisy (Leucanthemum, vulgare,
Lam). Some years since, a distinguished agricultural gentleman published a

PRELIMINARY DISCOURSES. IX

This ought not to be the case, among a people invested with the
lofty privileges which we enjoy. The rising generation, at least,
should be taught to notice what they see, — to observe, to think, and
to discriminate. Our young Farmers should learn to cultivate their
minds, as carefully as they do their acres; and not be permitted to
grow up in the neglect of their noblest faculties, — nor — as a modern
writer expresses it — be content "to wander among the productions
of Nature, with little more perception, or enjoyment of her charms,
than a cow on a common, or a goose on a green."

It is not unusual to hear persons say, that they should really like
very much to cultivate an acquaintance with the Natural Sciences —
and especially Botany, — if they only had time for such pursuits. —
I beg leave to suggest to these worthy people, that they have mis-
apprehended the true nature of their complaint, — and that they
not only deceive, but really flatter themselves, by relying upon such
an excuse. It is not so much the want of time, which afflicts them,
as it is the want of taste, and the neglect of opportunities. Most
people contrive to find time for what they earnestly desire to do ;
and if driven to the necessity, are apt to take it, at any rate, for
those pursuits which they are resolved upon. But the fact is, we
all idle away countless hours of our existence — especially in the
morning of life — which might be successfully devoted to the attain-
ment of useful knowledge*

It is true, indeed, that the higher intellectual enjoyments, afforded
by "the amiable Science," can only be fully understood by those
who are blest with a lively sense of the Beautiful, in Nature. Its
purest delights necessarily inure to votaries of that description ; for,
according to the proverbial philosophy of honest SANCHO PANZA —
" No es la miel para la boca del asno:" Yet it is no less true, that
taste is a faculty which can be cultivated ; and opportunities to be
improved, happen to all. Some of the most enthusiastic and suc-
cessful students of Nature that I have ever known, prosecuted their
inquiries under a constant pressure of the every-day cares and
duties of life ; and yet were remarkable for the exemplary perform-
ance of those duties. •{•

In reflecting upon the interesting character of Botanical know-
ledge, and upon the many inducements to acquire it, — one i3
naturally led to ask, why a rational acquaintance with the Vegeta-
ble Products which every where surround us, and are literally
strewed along our paths, should not be adequately inculcated in all
our Seminaries, — and especially I would ask, why such a humaniz-
ing and elegant Science should not be made an indispensable branch
of Female Education. As a mere accomplishment, it is intitled to
rank with any of those ornamental acquirements to which so much
time is devoted. As a means of enlarging the views, and disciplin-
ing the mind — training it to habits of correct observation, and
profitable reflection, — the Study of Plants is far superior to many
of the fashionable and fugitive attainments, which so generally
engross the attention of young Ladies. It is a pursuit, too, which
carries with it its own reward. The knowledge which it affords, is
at once pleasing in the acquisition, and of enduring value. It is
continually called for, and always at command, — ready to minister
to the instruction and gratification of the possessor — whether in the
Garden, the Field, or the Forest.

These Studies — said the Roman Orator, on another occasion — and
the averment is no less applicable here, — these Studies are the intel-
lectual nourishment of youth, and the cheering recreation 0jf age ; they
adorn prosperity, and are the refuge and solace of adversity ; they are
pleasant at home, and are no incumbrance abroad; they abide with us
by night — go with us in all our travels — and lend additional charms to
the attractions of our rural retreats.*

Those who make only occasional visits, or excursions, in the
country, will find their pleasure greatly enhanced by an acquaint-
ance with the Plants which mainly contribute to the charms of the
scenery: But, by those whose constant residence is in the midst of
the vegetable tribes, a reasonable knowledge of Botany should be
regarded — not merely as an accomplishment, but — as one of the
indispensable qualifications for the duties of rural life.f I have

already intimated the opinion, that an American Farmer should
blush to be ignorant of the objects of his peculiar care ; and I know
not why a Farmer's Wife, or Daughter, should be entirely excused
for a like deficiency. On the contrary, I am of opinion that it is to
Wives and Daughters we must look, for the commencement of a
salutary reformation in intellectual pursuits and discipline. The
work must begin at that early period of life, when the character is
being moulded under female auspices and care. The knowledge
here advocated, is unquestionably desirable for both sexes ; and I
sincerely believe, that the most effectual method for diffusing it,
will be — first properly to educate, and then — to invoke the co-opera-
tion of the Ladies. Their potent influence has been felt, and owned,
in many a noble cause ; and I cannot permit myself to doubt its
controlling eificacy in this.

DISCOUESE II.
Definition of the Vegetable Kingdom.

IN this Discourse, it is proposed to define what is meant by the
terms, Vegetable Kingdom, — and to notice those characters by which
a Plant is known, and distinguished from the other objects in
nature.

The material world has been arranged, by the generality of
Naturalists, in three great divisions, — which they have denominated
the Mineral, the Vegetable, and the Animal Kingdoms. These three
Kingdoms are, for the most part, readily distinguishable by the
jnost superficial observer; yet, so nearly do the tribes, on the con-
fines of the divisions, approach each other in structure and character,
that it is by no means easy, with descriptive phrases, or definitions,
to draw a satisfactory and unexceptionable line of demarcation
between them. We have no difficulty, indeed, in distinguishing an
Ox from an Oak tree — nor a cabbage from a boulder of granite : But,
when we descend to those humbler existences, called Zoophytes, and
Corallines, we are sometimes puzzled to determine which is Animal,
and which is Vegetable. Some of the lower orders of Plants, too,
(such as a portion of the Fungi, and Lichens,) are often so simple in
their structure, that they seem to be formed by a process somewhat
analogous to that of crystallization, — and therein are approximated
to the Mineral kingdom.

xii

PRELIMINARY DISCOURSES.

Various attempts have been made, by Naturalists, to designate
the distinguishing characters of the three great divisions. The
celebrated LINNAEUS, with his characteristic point, and brevity,
defined them thus: Stones (said he) grow; Vegetables grow, and
live; Animals grow, live, and feel.* It would be difficult, if not
impracticable, to giv« a better definition in the same number of
words : But the description furnished by Prof. DE CANDOLLE, will
probably be considered as more complete and satisfactory, -j-

The bodies existing in nature— says the distinguished and lament-
ed Professor of Geneva — may be ranked under two great divisions : —

I. INORGANIC BODIES, — or those which are rude, homogeneous in
their structure, destitute of life, and growing only by the mere
addition of similar particles to their exterior surface.

II. ORGANIC BODIES, — composed of heterogeneous parts, endowed
with life, and growing by the introduction of dissimilar particles
within the intimate tissue, or vessels of which those parts are
formed.

Inorganic bodies may be considered as of two kinds : Some of them
of immense magnitude, sphaeroidal in their figure, and distributed
through space, — constituting what are called Stars, or heavenly
bodies ; the others, comparatively small, situated on our globe, and
all tending more or less to the crystalline form, — being known under
the general name of Minerals.

Organic bodies are also of two kinds: the one destitute of sensation, of
voluntary motion, and of a stomach, — namely, Vegetables; the
other, endowed with sensation, capable of voluntary motion, and
furnished with an internal sac, called a stomach, — these are
Animals.

The foregoing classification may be recapitulated thus :

I. INORGANIC BODIES — dead, homogeneous, growing by juxta-
position : two kinds, —

1. One kind, celestial and sphaeroidal — Stars.

2. The other, terrestrial and crystallizable — Minerals.

* The following are the words used by him, whom PULTENEY designates as the
"high priest" of the Science -.—Lapides crescunt; Vtgetabilia, crescunt, etvivunt;
Animalia crescunt, vivunt, et sentiunt.

f The following, from AUGUSTS DE ST. HILAIRE, .presents, neatly and briefly, the
distinction between inorganic and organic bodies. " Parmi les corps qui nous
environnent, les uns, bruts et inertes, sont prives de mouvement et de vie; ils ne
naissent point, ils se formcnt; ils ne se nourrissent pas, Us s'agglomerent : ils ne
meurent point, ils se decomposent. Les autres, au contraires, naissent pourrus
d'organes destines a des fonctions diyerses ; ils vivent,se nourrissent, se deyeloppent,
et, avant de se decomposer, ils meurent. Les premiers sont les corps inorganiques»
les seconds lea corps organises."— Morphologic Vegetalc,

II. ORGANIC BODIES — living, heterogeneous, growing by intus-
susception ; two kinds, —

1. One kind, destitute of sensation, of voluntary! yegetdbles
motion, and of a stomach. /

2. The other, endowed with sensation, capable of \A- ^
voluntary motion, and provided with a stomach. /

Certain Naturalists have been so forcibly impressed by the con-
templation of the gradual and near approach of the two great
divisions of organized beings, that they have thought we should
admit of but a single class, — which they have designated* by the
name of the organic kingdom:. Others, again, have proposed to
establish an intermediate kingdom, between animals and vegetables,
to consist of Zoophytes, Sea-weeds, and Mushrooms. Both pro-
positions, however, have been rejected by the generality of Natural-
ists, with great unanimity.

On this head, and in further illustration of the subject, the
eminent Author here cited remarks — that those being& which seem
to us to be intermediate between animals and plants, ought rather
to be considered as evidences of our ignorance, than as proofs of
the existence of a peculiar class-; and although it may be correct to
Bay, that the two organic kingdoms havfrsuch striking resemblances,
and approximate so nearly, that a satisfactory line of demarcation
cannot be drawn, they nevertheless present differences of such a
character that it is useful to separate them, — seeing that these dif-
ferences exert an influence upon the progress of the study, in
the two kingdoms, and consequently upon the logic of the two
Sciences.

Assuming as a fact — or as an extremely probable hypothesis —
that Animals are endowed with sensibility, and that Vegetables are
destitute of it, we shall see resulting from that supposition, nearly
all the differences that we observe between animals and plants ; be-
tween Zoology and Botany.

Since Animals have a consciousness of their existence, and a
sensation of pain and pleasure, it is natural to suppose that they
should endeavor to avoid the former sensation, and seek the latter,
— that is to say, that they should be endowed with the faculty of
voluntary motion ; for, if we supposed them destitute of this faculty,
we should have no means of ascertaining their sensibility. Plants,
on the contrary, can perform no other motions than those which are
produced by external agents, or by certain mechanical circum-
stances of their structure. These motions can be neither voluntary,
nor truly locomotive.

XiV PRELIMINABY DISCOURSES.

An Animal, endowed with sensibility and the power of motion,
can select the food necessary for his subsistence, — and go in quest
of it, when he does not find it in his immediate vicinity; and can
seize it, in order to appropriate it to himself. He can, consequently,
nourish himself with various kinds of matter, — even with kinds
which are but partially distributed in nature — being such as are
already organized.

A Plant, on the contrary, being unable to distinguish what is
proper for its sustenance, or to seize any kind of prey, must neces-
sarily nourish itself with matters which are so generally diffused
over the globe as to be found almost every where ; which are suf-
ficiently inert to oppose no resistance to the feeble means of absorp-
tion with which it is provided, — and sufficiently soft and yielding
to require no mechanical division. Consequently, there are none
but inorganic substances — such as water, air, and matters which
are soluble in those two vehicles — adapted to that purpose ; and these
are, in fact, the substances which serve for the nutrition of plants.

Animals, then, can select for their nourishment, a great variety
of matter, — and consequently, the organs of their nutrition must
present a corresponding diversity : Vegetables, on the other hand,
are nearly all subsisted on the same materials, — and therefore,
their organs of nutrition are very nearly similar.

Animals, which select their food, often experience intervals in
which they are unable to procure such as is suitable for them ; and
when they do find it, they lay in a provision to last them for a
time. It is necessary, then, that they should be furnished with a
receptacle in which to deposit their store of nourishment: thia
receptacle is called the stomach. Plants, being constantly surrounded
by their appropriate aliment, and never changing their position,
have no necessity to lay in a stock of provisions, — and accordingly
have no stomach in which to receive it.

The nourishment of Animals being deposited in an internal cavity,
all the vessels of the animal are found converging toward that
centre : But in Plants, the absorbing vessels are directed toward
the surface. Animals, says BOERHAAVE, are nourished by internal
roots, — and Plants by external roots : Consequently, the structure
of vegetables will be calculated to multiply surfaces, — and will be
perfect in proportion as it is fitted to accomplish that object. The
organic structure of animals, having a central tendency, will be
perfect in proportion to the perfection of their internal organization.

Inasmuch as the essential seat of nutrition, in Animals, is placed
in the interior — and as the vessels are all directed toward and about
that centre,— those vessels must continue to perform the same

PRELIMINARY DISCOURSES. XV

office, during the existence of the animal: But the vessels of Plants
being directed to the exterior, there will be a constant possibility,
either of their being elongated, or of new ones being developed on
the outer surface. There will then, consequently, be a certain limit
to the growth of Animals; but none to that of Vegetables. There
will then, in Animals, be a death from old age ; which will happen
when the existing vessels — not being capable of renovation — shall
be obstructed by the influx and lodgment of the minute particles of
matter which are conveyed to them. This cause of death does not
occur in Vegetables — at least, not in perennial vegetables, — since
new vessels may be indefinitely developed, and take upon them-
selves the office of the old ones. Animals, therefore, die of old age,
or of accidents ; perennial Plants of accide'nts, only.

In consequence of Animals having a centre of nutrition, and of
life, it follows that they can rarely, if ever, be divisible into several
individuals ; for those animals called Polypi — which seem to be an
exception to this rule — ought rather to be considered as aggrega-
tions of a number of individuals : Plants, on the contrary, having
no common centre — and being endowed with the faculty of pro-
ducing new vessels to an indefinite extent — may be divided without
loss of life, and can be indefinitely multiplied by cuttings.*

From the general considerations thus presented, the following
Principles seem to result : —

1. That the differences between the two organized kingdoms
consist essentially in this, — that one of them is endowed with sensi-
bility, and the power of voluntary motion, of which the other is
destitute.

2. That the general office, or business of Plants — in the great
system of a wise and beneficent Providence — is to elaborate and
prepare inorganic matter, so that it may become fitted for the
nourishment of Animals :f and

* This is more particularly true, however, in those plants which form buds, and
live more than a single season; for the buds of trees, and shrubs, may be regard-
ed as so many distinct Individuals, congregated on a common stock. Even those
perennials with herbaceous stems, which die down to the ground every winter,
form a kind of buds in the crown of the root (or rhizomd), from which proceed
the aerial stems of the ensuing summer. Those plants called annuals (which
germinate from the seed, bloom and perfect their fruit, and die, as it were a natural
death, within the year) rarely produce anything like buds : and are by no
means so susceptible of division, or multiplication by cuttings, as the woody
perennialt.

t"It is one of the laws of nature that Animals shall feed on organized matter,
and Vegetables on unorganized. For the support of animal life, therefore, we
require vegetables to change the mineral constituents of the surrounding media
Into suitable nutriment."— Prof. HA&VIY.

3. That in the study of those two kingdoms, we should never
lose sight of the essential characters which distinguish them ; and
should extend the application of the principles, which are peculiar
to each, with great caution, — lest we be misled by a false analogy.

IN the preceding Discourse, we endeavored to furnish a definition,
or distinct idea, of the three great kingdoms in Nature, — and,
especially, to present a Sketch of the general resemblance, and dis-
tinguishing characters, of the two organic kingdoms, from the
learned Treatise of Professor DE CANDOLLE. We shall now proceed
to notice some of the more remarkable traits, and phenomena, of
the vegetable economy. For an illustration of the intimate struc-
ture, and physiology of Plants, the Student is referred to the
admirable Text-Book of Prof. A. GRAY : Our present purpose being
merely to speak of the external organs, — or those obvious appen-
dages, and features, which give character to the vegetable tribes,
and form the basis of classification.

It is a circumstance worthy of all attention, and admiration, that
the works of Nature — even those apparently the most complicated
and elaborate — are ever, when rightly understood, found to be per-
formed with extremely few materials, and by the simplest of all
possible processes. This truth is exemplified in the most interesting
manner, in the structure and economy of Plants. Infinite as are
the forms, and varied as is the texture, of the external organs of
plants, — it has been satisfactorily shown, that all those protean
appendages are, in fact, nothing more than a series of successive
modifications (or metamorphoses, as they have been termed,) of that
tissue which, in the germinating seeds, appears in the condition of
crude cotyledons, — and which in subsequent stages — as the plants are
developed and matured — is put forth in the more highly organized
State of stem leaves, floral leaves (or bracts], sepals, petals, stamens ,
and pistils (or young fruit}. For an early, ample, and most interest-
ing exposition of this doctrine, we are indebted to the celebrated

PEELIMINAEY DISCOURSES. STl

German Poet, GOETHE, — whose writings show him to have been no
less accomplished in Botany, than eminent in Belles-Lettres. *

In accordance with the view here presented, a Plant may proper-
ly be said to consist of root, stem, and leaves ; — all other parts —
under whatever name — being modifications of these. The limits
assigned to these discourses forbid a complete illustration of the
doctrine : but a brief sketch may be attempted, of the more strik-
ing modifications which the external organs undergo, during the
development of a plant: — i. e. in its progress from the germinat-
ing seed, up to the perfection of its fruit. Those who read French,
may find the doctrine elaborately set forth in SAINT-HILAIRE'S Mor-
phologic Vegetate ; and in our own language, it may be found briefly
but well explained, in the elementary works of GRAY, and LINDLEY.
To prevent misapprehension, however, it may be well to let the
student understand the precise and proper sense in which the term
metamorphosis is used, by the Botanists. "When, for instance, the
floral organs are called modified or metamorphosed leaves, it is not to
be supposed that a petal has ever actually been a green leaf,
and has subsequently assumed a more delicate texture and hue, or
that stamens and pistils have previously existed in the state of
foliage; but only that what is fundamentally one and the same
organ developes, in the progressive evolution of the plant, under
each or any of these various forms. When the individual organ
has once fairly begun to develope, its destiny is fixed." — GRAY'S
Text-Book.

It has been aptly remarked, that the best mode of explaining things,
is to show how they come to pass. That is the mode adopted by
GOETHE, in explaining the metamorphosis now under consideration ;
and it is the one we shall endeavor to pursue.

It will be borne in mind, that a sound and perfect seed (by which
is meant, one that is capable of vegetating,) is neither more nor
less than a plant in miniature — rudimentary, it is true, but an
organized, living plant, — existing in a dormant state, or what may
be called suspended vitality. It awaits but the joint application of
certain vivifying agents (namely, warmth, moisture, and oxygen,)
to rouse it into active life ; when its bursts its envelopes, and com-
mences its career of growth. The opinion, so generally entertained,

* It is due, however, to truth and justice, to say, that very fev important doc-
trines, or views, concerning the Vegetable kingdom, have yet been promulgated, of
which " the immortal SWEDE " had not some intelligent perception. The idea so
happily illustrated by GOETHE, had very nearly occurred to the mind of LINNAEUS,
about the middle of the last century. It was first distinctly enunciated by C. I'R.
WOLFF, in 17 64.

that "seeds must die before they can come up," is a vulgar error.
Seeds that die, never "come up." The error probably originated
from observing the condition of the albumen, in seeds of the cerealia,
or edible grains, at the period of germination. The efficient cause,
or intimate nature, of growth, we do not, of course, pretend to
understand. Such knowledge is now — and perhaps will remain —
beyond the reach of finite beings ; but the physical agents concerned
— their operations and results — and the laws which regulate them —
the curious observer can both perceive and comprehend, to a very
satisfactory extent. The solid portion of Plants is made up, mainly,
of an infinity of slender fibres, and delicate membranes — forming
tubes, and cells, for conveying and containing fluids ; and the
physical process of growth consists in the extension and multiplica-
tion of those tubes and cells. When the fibrous portion (which
results from elongated cells,) predominates, the plant becomes firm
and woody; and when the strictly cellular structure prevails —
whether in stem, leaves, or fruit — the product is fleshy, tender and
succulent. The same wise Power which endowed plants with
vitality, and the capacity for growth, or development, has also
established laws to control that development, — whereby each plant
assumes a determinate form and character; which, although liable
to variation in the subordinate features (as in texture, size, color,
or other trait of secondary importance in the vegetable economy),
are nevertheless essentially perpetuated in the species. It is this
fixedness of character which enables the Botanist to recognize, and
distinguish, the various kinds, — and, in classifying them, to ar-
range each with its kindred.

But our present business is with the changes or modifications,
which successively take place, at successive stages of development, in
the foliaceous appendages of the same plant. Naturalists have
observed, that in the stems and branches of plants, there are small
portions, found at certain intervals, which are more firm and dense
than the other parts. These firmer portions are termed knots, or
nodes, — and the intervening spaces are called internodes. These
nodes exist, under some form, and in greater or less abundance, in
all stems: sometimes being crowded together, and condensed at
certain points of the stem, so as to form complete, and often solid"
rings (or joints, as they have been rather incorrectly termed) ; at
others, they are much divided, and appear in scattered points on
the circumference, — in which latter case, they are usually disposed
in an ascending spiral line. They seem to have an intimate con-
nection with the formation of all leaves, and buds, — and are, at least,

the starting points from which those organs are evolved, during the
growth of the plant.* Even the stem of the embryo plant, as it exists
in the seed, has its nodes, — with the first of which the cotyledons
are connected, and at the next above, we find those minute expan-
sions known by the name of primordial leaves. The internode*, or
spaces between those little knots in the stem, may be long, or
short, — which will, of course, determine the distance between the
leaves. They may be so short as scarcely to be perceptible, — in
which case the leaves will necessarily be brought close together, in
tufts or bunches ; or they may even be wholly suppressed, as it is
termed, — so as to reduce the leaves to the same plane ; either in
opposite pairs, if but turn are developed, — or in vchorls of the normal
number in the circuit of the stem, if all are developed. If the nodes
are scattered, or disposed in a spiral line, the leaves, of course, will
be arranged in the same order, on the stem and branches. Thus we
are furnished with a key to the whole mystery of the arrangement of
leaves and buds, — and consequently, of the branches, which arise
from the buds. We shall now be prepared to watch the development
of the foliaceous appendages of the plant, — and the successive changes
of their form and character, as the stem ascends. The cotyledons (in
that large division of the vegetable kingdom which is provided with
two of those organs,) are always opposite, — as likewise are, for the
most part, the next pair of leaves — called primordial : but the suc-
ceeding ones are variously arranged, in different families — either
alternate, opposite, or vtrticillate. The leaves on the stem, and
branches, usually differ in form, also, from those early rudimentai
leaves which appear at germination. If the plant is duly nourished,
the leaves are apt to be well developed until it has reached its
destined height — or is sufficiently matured far flowering, — when they
usually become smaller. In several natural families, there are
foliaceous appendages, or accompaniments, at the base of the leaves,
or petioles, which seem to be a sort of exuberant growth, or super-
numerary products : these are called stipules.

In sterile, or ungenial soils, the leafy expansions are less com-
plete, and are liable to modifications which appear to be the acci-
dental result of defective nourishment, — though they often become
fixed, and permanently characteristic. Prof. DE CANDOLLE terms

* Sometimes the bud— instead of being in the axil of the leaf, as is usual— is
formed and situated directly under, and within, the base of (he petiok ; in which
case, consequently, the hollow base of the petiole covers the bud, as an extin-
guisher does the stump of a candle. This feature is well exhibited, in autumn,
by the Buttonwood Tree (Platanus); and may be likewise observed in the common
petioles of the Bhus, the Rdbinia, and the Cladrattis (or Virgilia).

the process, degentrescence — i. e. a sort of degeneracy, or habitually
stunted growth, Thus, in some plants, we find the true stem-leaves
habitually curtailed of their fair proportions, — compound leaves
being reduced to simple disks, or dilated petioles, called phyllodia,
— simple leaves starved into mere needle-like processes, — and stipules
shrunk into prickles ; while even woody branches, under a similar
privation, often appear in the character of true thorns. By taking
this view of the vegetable economy, we are not only led to contem-
plate the various modifications with great interest — but are put
completely on our guard against any illusion, or misapprehension of
the real nature of apparent irregularities, or so-called anomalies. —
We know that the proper place to find a leaf, is at the nodes: "We
shall generally find one there. It will sometimes be very small —
sometimes reduced to a mere scale, or midrib — or it may even be
entirely wanting ; but that's the place to look for it, — and if we find
any thing occupying the normal position of a leaf, or stipule, we shall
be prepared to understand its true character. So of the other organs.
Whatever strange-looking appendage we may find in the proper
position of any organ, — we shall at once comprehend, that it is some
disguised form, or modification, of that particular organ.*

* This view of the subject, I would wish to impress strongly, and distinctly, on
the mind of the Botanical Student. Every organ of a plant being liable to modi-
fication, we must take care not to be misled by appearances ; but be constantly
suspicious of all disguises, or deviations from regular structure, and symmetry. —
The clew to real character — as intimated in the text — will be afforded by the posi-
tion of an organ. In the grape-vine, for example, those anomalous organs, called
tendrils, will be found occupying the normal position of flowering branches; and
observation has shown that they are, in fact, nothing but abortive or metamor <
phosed racemes. They may be often seen in the transition state, — some of the
subdivisions of the tendrils actually l>e&ringjlou>ers. Prof. DE CANDOLLE even con-
sidered the main stems of twining plants as partaking of the character, and verg-
ing towards the condition, of tendrils ; and his opinion is rendered plausible by
what we see in many climbers. In some species of Clematis, and in Adltimia, the
petioles, or footstalks of the leaves, perform the office; and in the vetches, or Pea
tribe, the common petioles usually terminate in real tendrils. In certain leafless
plants — such as the Opuntia, or prickly Pear, and some species of Phyllanthus, —
the stem assumes the flat, dilated figure — and, to some extent, actually performs
the function — of leaves : But, with the aid of our Theory, there is no danger of
mistaking the real character of any of these " counterfeit presentments."

The change of calyx, and receptacle, into apparent fruit — by reason of the
copious development of cellular tissue, in those organs, is not an unusual occur-
rence. Their position, however, in relation to the other parts of the flower, ren-
ders the circumstance perfectly intelligible.. The gradual conversion of pistils,
or carpels, into the countless varieties of mature fruit, is readily explained by
this development of tissues. In their early, rudimental stage, at the opening of
the flowers, the texture of the carpels is very similar in all plants; but, during
their growth, and progress to maturity, a great change is effected in the different

PRELIMINARY DISCOURSES. Xxl

When a plant is full-grown, or sufficiently matured to bloom, a
striking change takes place. Slender branches are often thrown out,
— or the internodes near the summit of the stem become suddenly
elongated ; there is usually, also, a great diminution observable in
the size — and frequently an entire change in the outline, or figure —
of the foliage, on the flowering branches. Next we find, in many
instances, a sort of transition leaves, called bracts, in the immediate
vicinity of the flowers. These bracts are sometimes scarcely changed,
in appearance, from the other leaves on the stem and branches ; but
we find them, occasionally, assuming the hue, and almost the tex-
ture, of petals. Having thus ascertained that bracts are nothing
more than modified leaves, — we now approach the flower, itself, —
which is always the termination, or concluding development, of a
stem, or branch;* and here we find, in many plants, a whorl of
green leaflets (or sepals — composing what is called the calyx,} at the
base of the flower, so little altered from the small leaves immediate-
ly below, that we have no hesitation in considering them as of
precisely the same nature; — the only difference being, that, by the
suppression of internodes, they are arranged in a ring (called a
verticil, or whorl,) at the summit of the peduncle, or ultimate branch
of the flower-stalk. This is the regular mode of arrangement, of all
the parts of a flower. The sepals, petals, stamens — and even the
pistils, in symmetrical flowers (i. e. when all the parts, which normally
belong to them, are present) — are all disposed in a succession of
verticils. In the flowers of the DICOTYLEDONS, or Exogenous Plants,
each floral verticil, when complete, is composed of five modified
leaves — or some multiple of that number. It may — and often does —
vary from this, by reason of a suppression of some of the parts ; but
five is the normal, or what may be termed the constitutional number,
in the floral verticils of that great division of the vegetable king-
kinds — according as the rascular and fibrous, or the cellular, tissue predominate?.
In the one case, we have dry, skinny, woody, or even bony, seedvessels; and in
the other, we find the product to be Qeshy, pulpy and succulent fruits. Even in
the same pericarp, we often see one portion tender and juicy, — while another
portion is parchment-like, or bony; as in pomes, and drupes — or apples and
cherries. It is only necessary to extend and apply this doctrine to all the modified
organs of plants — and to keep the idea constantly in mind — in order to compre-
hend the whole mystery of metamorphosis.

* Although, for convenience in descriptive phraseology, we often say that flowers
are lateral, axillary, sessile, Ac., it should, nevertheless, be constantly borne in
mind, that a flower is always the terminal and crowning development — as the
fruit is the final product— -of a stem, or branch; that the pedicels of aggregated
florets are the ultimate ramifications of the main flowering stalk, — and that wheu
a flower appears to be sessile, it is merely by the suppression — more or less com*
pletc — of the internode which normally constitutes its proper peduncle.

SX11 PRELIMINARY DISCOURSES.

clom. Often, indeed, one or more entire verticils are suppressed, —
presenting flowers destitute of calyx, or corolla — or sometimes with
one of these, and either the stamens, or pistils, also wanting.* In
the MONOCOTYLEDONS, or Endogenous Plants, — such as the Liliaceous
and Orchideous tribes, Grasses, Sedges, &c., — three, and its multiples,
constitute the regular, symmetrical number, of the members of each
floral verticil ; but they are often incomplete, or wholly suppressed.
In the Liliaceae, we frequently find some of them doubled, — while
in the Grasses, and Cyperaceae, all but the ataminate verticil are
usually deficient.

The leaflets, or component parts of the several verticils, are in
many instances all free — i. e. separate and distinct from each other ;
and this is regarded as their normal or regular condition : But we
often find them united, or cohering together, to- a greater or less
extent — either by their margins, or surfaces, or both ; and this
union is apt greatly to disguise their primitive character. Such
cohesions, or solderings, as they are termed, are analogous to the
process of ingrafting, or rather inarching, — and may be readily sup-
posed to take place while the tender organs are closely packed
together, in their forming stage. Sometimes the sepals are united
by their margins, so as to form a cup, at the base of the flower, — and
this suggested the name of calyx. When the union is nearly com-
plete, a careless obserrer might be puzzled to know whether the
calyx were really compound, or simple, in its structure ; but our
theory leadsus to lo-ok for evidences of a compound structure, — and we
accordingly find them in the free points of the sepals, which are
usually obviows enough, under the name of segments, or teeth, —
and also in the seams, or sutures, formed by the junction of the
margins. The union of the petals is often quite as remarkable as
that of the sepals, and sometimes greatly obscures the normal struc-
ture,— as we see in what are called personate, and labiate flowers.
Similar cohesions take place, likewise, among the stamens, and
pistils. The modified leaflets, or parts of the same floral verticil,
are not only liable to cohere with each other, — but the different
verticils are also frequently soldered together, at base — so as to form

* Flowers are termed symmetrical, when all the parts of each verticil are devel-
oped; regular, where the parts, present in a verticil, are all of the same form and
size; complete, when both calyx and corolla are present; and perfect, when each
flower is furnished with both stamens and pistils. When stamens, or pistils, are
defective, or wanting in & portion of the flowers, while they are perfectly developed
in others, the flowers are said to be polygamous ; and they are termed monoicous,
or dioicous, when simply staminate, or pistillate, — according to their distribution OB
the same, or on different, plants.

one concrete mass ; in which case the ovary (or young fruit) appears
to be below the flower, and is said to be inferior, though it is really
above, — being within the tube, formed by the cohering sepals, &c.,
and consolidated therewith.

The next regular verticil, above the calyx, is called the corolla.
The leaflets of this, are usually much more changed than those of
the calyx; but even here, we find such various intermediate forms as
clearly show that the petals, also, are nothing but modified foliage.
In further corroboration of this view, we observe in many plants
what seems to be a kind of supernumerary verticil, — sometimes situ-
ated between the calyx and corolla, and sometimes between the
corolla and the stamens ; which supernumeraries are apt to be very
curiously modified, — and are obviously in a state of transition, either
from sepals to petals, or from petals to stamens. These are com-
monly called nectaries. The same remarks apply to the two remain-
ing regular verticils of the flower, known as stamens, and pistils.

Singular as it may seem, to the uninitiated, even those organs
are now regarded as leaflets, which have reached the final stage of
metamorphosis ; for both have been detected in such form and condi-
tion as clearly betrayed their foliaceous origin. The reciprocal con-
vertibility of petals and stamens, is a fact familiar to every Tyro in
Botany. All double flowers — so common under high garden culture
— are familiar examples of staminate verticils being expanded into
petals, instead of conforming to the regular law of their nature ;
and hence, those exuberant developments — so much admired by
Florists — are considered by Naturalists as accidents, or monstros-
ities.

The pistils, too — which comprise the young fruit— although less
frequently, are subject to a similar imperfection ; and the very ovules,
or rudiments of seeds, have been found retrograding, — so as to
exhibit their tender cotyledons in the form of leafy expansions.*
Thus, it appears that the whole of the external organs of a Plant
may be fairly regarded as so many leaves, in various successive

*Each simple pistil may be regarded as & folded leaflet, in the last stage of modi-
fication, preparatory to the formation of ovules, — and is often termed a carpel, or
little fruit. The ovules are usually produced on the margins of the metamorphos-
ed leaf, — and arc arranged on the placenta (supposed to be formed by the union or
decurrence of their pedicels), along the seam, formed by the junction of those
margins. When there are several pistils, or carpels, in one flower — and those
soldered together, — we have, of course, a compound fruit, with several cells; i. e.
a cell for each carpel. But some of the ovules — and even entire cells, or carpels —
may be, and often are, wholly suppressed, or abortive; thereby impairing the
symmetry of the structure — but leaving the phenomenon perfectly intelligible.

stages of metamorphosis, from their origin to their end — from seed
to seed again.

DISCOURSE IV.
Classification of Plants. Artificial and Natural Methods.

HAVING seen that the external organs of Plants consist, funda-
mentally, of those appendages called leaves, — which are regularly
modified, and prepared for their several functions, at the successive
stages of the vegetable career, — we shall now proceed to notice
some of the Methods, by which Naturalists have proposed to facilitate
a more extended and particular acquaintance with the different
kinds: — i. e. with the Genera, and Species, of the vegetable king-
dom. Although the organs of the various tribes assume an almost
endless variety of forms, and aspects — and even in the same species,
are subject to considerable modification, by the influence of culture,
soil, climate, and other circumstances, — it has been observed, never-
theless, that the peculiar structure, and essential character, of each
particular family, are remarkably constant, and well defined. Even
the monstrosities produced by long culture, disease, or other accident,
usually retain enough of their primitive features to enable us to
recognize them, under all their disguises. It is this constancy, or
permanence of character, which affords the basis of all classification ;
and classification, or the grouping together of kindred individuals, is
the apparatus by which our conceptions of objects are so arranged,
and fixed, as to secure a comprehensive general view, — while it
facilitates all subordinate and detailed investigations.*

The most important, or conspicuous organs of plants — their most
constant and characteristic features — whether consisting in the struc-
ture, the presence, or even the absence, of particular parts, have

*It would be impracticable, without the machinery of classification, to make any
important advances in Natural knowledge, — or to leave any durable traces of
our progress, in such knowledge, for the benefit of those who come after us. To
use a nautical term, we must bday all the information we acquire, if we wish to
render it permanently available to others : and the best belaying fixtures, to pre-
vent entanglement and confusion in Natural History, will be found in the most
lucid and practical systematic arrangement. " Omnia " — says LINNAEUS — " quae a
nobis vere dignosci possunt, dependent a CLARA METHODO, qua distinguimus similia a
dissimitibus."

accordingly been employed by the early Botanists, in constructing
systems of classification.*

Some have based the arrangement on the texture and size of
plants — classing them in divisions of Herbs, Shrubt, and Trees; others,
again, on the structure and form of the Calyx, the Corolla, the Fruit,
&c. or on the presence, or absence, of some important organ: And,
in our own times, the favorite object — following JUSSIEU and DE
CANDOLLE — is to arrange plants strictly according to their affinities, —
to group together, in Orders and Tribes, those which are most
nearly related in all the features, and properties, which constitute
character. These various Systems may be all regarded as forming
only two kinds, — namely, the Artificial, and Natural Methods; —
though, in point of fact, the artificial methods are more or less
founded in Nature, — and in the most perfect natural arrangements,
yet devised, artificial sections, or groupings, are still resorted to, as
useful helps and expedients. "What we call a natural method" —
says the excellent Prof. GRAY — "is so termed merely because it ex-
presses the natural relationship of plants as far as practicable ; for
every form yet contrived, or likely to be devised, is to a considerable
extent, artificial."

The great and obvious defect of the methods called artificial, con-
sists in their being founded on the fewest possible characters, —
whereby plants are arbitrarily brought together without reference
to their intimate structure, or general relationship with each other ;
and hence it often happens, in such methods, that plants which are
essentially dissimilar, are arranged side by side ; while kindred species
are widely separated. This defect is inherent in all artificial systems ;
and therefore, the most of them are only tolerable on account of
the facilities which they afford in determining unknown genera and
species — or ascertaining the names of particular plants. The system,
however, which was devised by the celebrated LINNAEUS, has the
merit of combining some of the advantages of both the artificial and
natural methods ; and will probably long continue to be employed,
as a convenient and useful help to the investigations of young
Beginners. It is, indeed, very remarkable, how many natural
families of plants are kept nearly entire, under the Sexual System.
The Linnaean classification, of the flowering plants, is founded on
the characters of two of their most important organs, — namely, the

* The late Professor B. S. BARTON, in his Elements of Botany, has given a Syn-
opsis of seventeen different methods of artificial arrangement,— from that ofCAESAL-
PISUS, "the Father of Systematic Botany"— which was published in 1583— down to
the Linnaean method, as modified by THUXBERG, near the close of the last century.
As a matter of curiosity, they are worth consulting.

ttamens, and the pistils. The primary divisions, or Classes, are
established mainly on the number, situation, proportion, and connec-
tion, of the stamens ; while a large portion of the secondary divisions,
or Orders, is based simply on the number of the pistils. Some
exceptions occur in the foundation of the Orders : but they are all
very intelligible, and readily understood by the student. It is
obvious, therefore, that nothing can be easier to acquire, than a
knowledge of the Linnean Classes and Orders. The practiced eye
— even in a flower that it has never before seen — determines them
at a glance.

The genus, and species — which are the remaining subdivisions — are
to be ascertained as in all other systems; the former, from the
structure of the flower and fruit, — the latter, from the peculiar
and permanent characters of the residue of the plant.

It has been often objected to the Linnaean method, that there
are too many exceptions to the rules of classification, — that a num-
ber of genera comprise species which, according to the system,
belong to a different Class, or Order, — and thus mislead and puzzle
the student. This objection is undoubtedly founded on fact ; but
the inconvenience has been somewhat exaggerated, — and may be
greatly remedied, and almost obviated, by simply putting a list of
those anomalies at the foot of the respective orders, where the sys-
tem would lead us to look for them. Where this is carefully done,
it even seems to facilitate the determination of such irregular
species, — directly pointing them out by name, and designating the
genera to which they severally belong. It may be questioned,
moreover, whether the exceptions in the definitions of many natural
Orders, are not even more numerous than those complained of in
the Linnaean method. Instructive, and delightfully interesting, as
is the contemplation of the truly natural families, — it seems to be
necessary to make the definitions of some of them very loose, and
comprehensive, in order to embrace all the individuals admitted to
belong to them : * so much so, indeed, that unless the student has

* Take, for instance, the very first family, in Prof. DE CANDOILE'S method of
arrangement — viz. the order RANUNCCLACEAE ; where we find the following diver-
sified— not to say incongruous — characters, enumerated in the definition of the
order:— Her bs, or woody vines, with leaves variously dissected, or entire— polypetal-
ous, or apetalous — flowers regular, or irregular — sepals 5, 3, or 15 — petals 3 to 15,
or wanting — stamens indefinite, rarely few— pistils many, or few, rarely single —
fruits either dry pods, or akenes, or berries, 1, or several-seeded ! This is, unques-
tionably, a correct outline of the features of a natural family — sketched, too, by
the hand of a master; yet, a Beginner in Botany would probably be apt to think
that as a definition, it is rather indefinite,— and he would, no doubt, be thankful
for any artificial helps that might tend to facilitate his researches.

already acquired a considerable knowledge of the vegetable tribes,
he often finds himself puzzled, and discouraged, in his attempts to
ascertain the names, and true position among them, of specimens
which are new and strange to him. In order to abate this incon-
venience, it has been found expedient, from time to time, to remove
the most discordant members of the old families, and make them
the types of new orders ; and in this way, the number of the orders
has been exceedingly multiplied. In fact, their name is legion ;
and the danger is, that it will soon be more difficult for the young
Botanist to ascertain the natural Order of a strange plant, than it
was to determine the genus and species, by the Linnaean method.
The learned and sagacious JUSSIEU — who first elaborated and
published a Natural System, in 1789, — arranged the vegetable
kingdom in 15 Classes, and 100 natural Orders, or Families: but
the great work of ENDLICHER, in 1840, gives us no less than 61
Classes, and 277 Orders, — with Tribes, and Sub-tribes, almost in-
numerable. These Orders are continually multiplying ; for, when-
ever the acute investigations of our modern Botanists detect incom-
patibilities in any member of an existing family, a new Order is
forthwith created, for its reception and accommodation. The ex-
pedient is very convenient — and no doubt very proper : though it
obviously threatens to result in an appalling multitude of Orders, —
which may require some artificial devices, to furnish a practical
clew to the position of unknown plants, in the great labyrinth of
Flora.

But, after all — however convenient and agreeable may be the
aids afforded to the Beginner, by artificial methods, — and however
intractable some genera may be, in associating with any known
natural Orders,— it must be confessed, that the method which teaches
us to investigate the essential characters and true relations of
plants, and which enables us to arrange them in kindred groups,
according to their respective affinities, is the only true philosophical
Botany;— the only method, in short, which entitles the pursuit to
the appellation of a Science. Although— as we have just intimated
— the relationship between the members of some natural orders, as
at present constituted, is not very striking, — yet there are numerous
and vast groups, composed of plants so obviously related to each
other, that all the world — both learned and unlearned — have con-
curred in referring them to the same family. Of these, it is suf-
ficient to mention, here, the great natural Orders of Grasses, Um-
belliferous, and Leguminous Plants— and those bearing what are
called Syngenesious, or Compound Flowers. We may add, moreover,

that those anomalous structures, which seem to have no immediate
connections — and are, at present, excluded from every known Order,
— may yet find near relatives in the unexplored regions of the
vegetable creation; and that future discoveries may possibly sup-
ply all the links, which now appear to be wanting, in the great
chain of organic existences.

In the mean time, — to those who are commencing the study of
Botany — and especially to such as have no other aid than books, —
I would say — Avail yourselves of the Linnaean Method, as the
easiest stepping-stone to the vestibule of the temple, and the
readiest means of acquiring the names, and learning some of the
characteristics, of the more common plants around you. In this
way, an immediate interest in the pursuit will be excited, — which is
indispensable, and can only be effected by successful research ; for, if
the student is met by repulsive difficulties at the threshold, he is
apt to be discouraged, and to abandon the undertaking.* But,
while I concede this much, in order to enlist you in the delightful
enterprise, I would add, and earnestly enjoin upon you — as soon as
you have effected these preliminaries — to make-it an invariable rule
to refer every plant to its appropriate place in the Natural System ;
to study its characteristic features, and examine with a scrutinizing
eye, all its relations to kindred objects. I would furthermore
recommend, to all who are bent upon mastering the Science, to
commence a Herbarium, from the start, •f Establish a correspondence,

* While I admit that a mere acquaintance with the names of objects, is the most
superficial kind of natural knowledge, — observation has satisfied me, that even
such knowledge is useful to Beginners in the Science, by the early encourage-
ment, and hopeful stimulus, which it imparts to their researches. I think there is
force, and good sense, in the following passage from a writer in the last century : —

" Let it be considered that the first degree of wisdom is to know things when
we see them — i. e. to know them by their names; and without this knowledge
scarce any progress can be made. To know the letters of the alphabet, to join
them into syllables, to understand words, is not solid erudition; yet it is absolutely
necessary for him who would become learned. Thus the characters and names of
things must be thoroughly learned in order to obtain any use from Natural
History. We find in the journals of travellers, many things mentioned, partly
curious, partly useful, concerning animals, plants, and stones; but those obser-
vations can be of no use to us, till we are able to refer each to its genus; that we
may make them a part of the system, and know that this curiosity, or use, belongs
to this or that object, when it happens to come in our way." — GEDNER, in STILLING-
FLEET'S Tracts.

fThe young Botanist should make it a rule to collect and preserve good speci-
mens (one or two for himself, and some for his friends,) of every species, and
remarkable variety, that occurs to him in his walks ; labeling them carefully —
•with the name, when known, — but, whether known or not, at once, and invari-
ably, noting the place of growth, and the time when obtained, — together with any

and a system of exchanges, where practicable, with competent and
zealous Botanists, in other districts. Be very inquisitive, whenever
you have a chance to confer with such, — for they are always happy
to aid the researches of the hopeful student ; furnish them with
specimens, and ply them with questions. Questions, when rightly
directed, and intelligently put, are a most effective apparatus for
eliciting information, and bringing truth from her hiding place.
A witty rhymer, of the age just elapsed, thus quaintly, yet aptly,
illustrates the character and importance of Interrogatories :

"The Sages say, Dame Truth delights to dwell—
Strange mansion ! in the bottom of a well :
Questions are then the windlass and the rope,
That pull the grave old Gentlewoman up."

The acquisition of the Language of Botany — or those technical
terms which are necessarily employed in the Science, — is generally
considered, by Beginners, as a most formidable part of the under-
taking: But this will be found, in a great degree, to be an im-
aginary difficulty. I admit that it would be a task, as irksome as
it would be unprofitable, to attempt ty learn the meaning of a parcel
of uncouth terms, without knowing their origin, or comprehending
the objects to which they are applied. Such is not the mode in
which I would study, or try to teach, the natural sciences. Rather
let us look at the objects, and examine their structure. We shall

characteristics which are liable to be obliterated in pressing and drying.f These
notes will serve him as valuable Mnemonics, in any future references to his
Herbarium. On all suitable occasions, he should diligently explore the vegetable
products of the region, or district, where he resides :— not neglecting such other
localities as he may happen to visit. In that way, he will soon be surprised at the
extent and value of his collections; and will find a pleasure, and an interest, in
Lis herborizing excursions, which the uninitiated can neither appreciate nor com-
prehend. In those excursions, a friend who can sympathize with his predilections,
and cordially participate in his researches, will always prove an agreeable and useful
companion: But I .fully concur in the shrewd advice of my old Correspondent,
Dr. E. GERMAIN, DE SAINT-PIERRE, in his Guide du Sotaniste:—

"Jamais, n'herborisez avec les personnes etrangeres a vos etudes; vous les
fatigueriez bien vite par vos allures irreguliercs, vos terns d'arret ou votre marche
precipitee ; tandis quo, d'autre part, 1'air contrarie de votre compagnon, prive
d'un auditeur et s'etonnant que vous regardicz une plante commune ou vous
demandant si vous ne 1'avez pas dejk recoltee, vous serait a vous memo une in-
supportable gene. Gardez-vous surtout d'entreprendre, dans de telles conditions,
un long voyage : son but serait absolument manque."

fin collecting plants for & Herbarium, and future examination, it is always
desirable, when practicable, to have specimens of the fruit, — as well as of the
flowers, leaves, &c. " Every botanical specimen," says Prof. HARVEY, "should bo
an epitome of the essential marks of a species." The Student should distinctly
understand, that the full grown fruit is indispensable in determining many of the
Carices,— and also of the Cruciferae, and Umbelliferae. He should, therefore, be
careful to make hia collections accordingly.

then perceive organs, or features, which serve as convenient marks
of distinction between different objects. Those organs must neces-
sarily be designated by some name, or term — in order that they
may be intelligibly spoken of, or recognized when referred to :
and I venture to say, that every one who makes an acquaintance
with such objects, — so far from finding the names to be burthen-
some — will feel the absolute necessity of them; and will take a
lively interest in their acquisition. We should undoubtedly find it
a dull and insipid employment, to take up a City Directory, and
commit to memory the names of the Inhabitants : But, if we were
to go among them, and form some interesting acquaintances, we
should find no difficulty — nor should think it any trouble — to learn
the names of our new friends. Now, the process should be precisely
similar, in the study of Nature. We ought never to waste our precious
time in learning mere names, apart from objects, — nor in attempting
to load the memory with such useless lumber. I say attempting ;
for it is not possible to fix permanently in the memory, any names
which are not associated with something like distinct conceptions of
the things to which they are applied. Such abstractions amount
to nothing more than an unmeaning jargon ; and therefore speedily
vanish from the mind. I repeat it, then, that in the NaturaJ
Sciences, the study of names, and things, should always go together.

DISCOURSE V.
Linnaean Classification. Natural System.

THE Linnaean method of Classification — as has been already
stated — is based chiefly on the stamens and pistils ; and is, con-
sequently, attended with this inconvenience, — that the class of an
unknown plant can only be determined, with certainty, while it is
in flower. The flowering season, to be sure, is the most agreeable
time to botanize ; but we cannot always procure our specimens in
that interesting state, — and hence we soon discover the advantage
of such a general knowledge of vegetable structure, as is afforded
by the study of the natural system.

LINNAEUS arranged the whole vegetable kingdom in 24 CLASSES,
— 23 of which are appropriated to flowering plants, and are founded
on some circumstance of the stamens, — the 24th being established

PRELIMINARY DISCOURSES. XXXI

on tlie absence of visible flowers. The first 13 classes are disposed
numerically, — according to the number of distinct stamens, of about
equal length, inserted on the receptacle of each flower, — with the
exception of the 12th (Icosandria], in which the stamens (occasion-
ally few, and sometimes very numerous — though usually about
twenty, as the name indicates,) are inserted on the calyx; and it is
this insertion which constitutes the essential character of the 12th
Class. From Class 1 to 10, inclusive, the number of stamens is the
same as the number of the Class. The llth Linnaean Class (called
Dodecandria — meaning 12 stamens) was made to comprise all plants
with more than 10 and less than 20 stamens; but such plants —
being few in number — have been referred (very judiciously, as I
think), by some modern Botanists, to the Class Polyandria, — which,
consequently, contains all plants with more than 10, distinct, or
separable stamens, inserted on the receptacle. The Class next after
Polyandria (called Didynamia — 14th of LINNAEUS), contains plants
having 4 distinct stamens in unequal pairs — one pair being regularly
longer than the other; and the succeeding Class (Tetr adynamia,)
has 6 distinct, unequal stamens, — 4 of them being longer, and 2
opposite ones short. The next three Classes are founded on the
union of the stamens, — or rather of their filaments — the anthers being
free: the Class Monadelphia usually having numerous stamens,
with the filaments all united together in a tube, or single set ; the
Class Diadelphia having mostly 10 stamens, with the filaments
united in two sets (usually 9 and 1), and the corolla generally in the
form called papilionaceous, or butterfly-shaped ; and the Class Polya-
delphia having numerous stamens, united in three or more sets, —
but, as the union is often slight, and the filaments — especially in
dried specimens — incline to separate, the plants of this Class have
been referred to Polyandria. The Class next following those
with united filaments, is a very large one, with united anthers
(named Syngenesia], and what are called compound flowers — i. e. the
floral developments (which are often large and showy,) are really
composed of many little flowers, densely crowded in heads, on a
common receptacle, — the heads being embraced, or supported, by
numerous bract-like leaflets, which constitute what is termed the
involucre. The succeeding Class (Gynandria,] has the stamens
inserted on the pistils — or those organs so united, and often so
intimately blended, as to render them rather obscure, to the inex-
perienced observer.

In the preceding Classes, the stamens and pistils are mostly in the
tame flower; but in the three following — which conclude the

XXxii PRELIMINAKY DISCOUKSES.

flowering plants — those organs are generally in separate flowers, —
and are thus classified: — In the 21st Linnaean Class, named Monoe-
cia, the stamens and pistils are in separate flowers, on the same
plant: In the next Class, called Dioecia, they not only occupy
separate flowers, but those flowers are on different plants.

There are, however, a number of plants, in which the stamens
and pistils are separate in some flowers, and associated in others —
either on the same, or on two, or even three, different plants. These
anomalies, LINNAEUS placed in a Class which he named Polygamia ;
but they have been, by later Botanists, distributed among the other
Classes.

The 24th, or last, of the Linnaean Classes (now more commonly
numbered as the 21st), is named Cryptogamia. It comprises those
multitudinous vegetable forms which seem to be destitute of flowers,
— or, at most, have only the analogues, or equivalents, of stamens
and pistils. The subdivisions of this Class are, of necessity, in
accordance with the natural system ; and the genera are therefore
grouped in appropriate Orders — as Ferns, Mosses, Lichens, Fungi,
and Algae.

The ORDERS, or secondary divisions, of all the Linnaean Classes
— from Monandria to Polyandria, inclusive — are founded on the
number of distinct styles, or stigmas, — and are numerically arranged.
The Class Didynamia is divided into two Orders : — one, called Gym-
nospermia, because it produces a thin-coated, and usually 4-lobed,
fruit, resembling naked seeds, or nutlets : the other, bearing mani-
fest seedvessels, and therefore named Angiospermia. The Class
Tetradynamia is likewise divided into two Orders — founded on the
size, or rather length, of the fruit, one, called Siliculosa, having a
Silicle or short pod, — and the other, Siliquosa, with a Silique or long
pod. In the remaining Classes of the flowering plants — with the
exception of Syngenesia — the Orders are established on the number,
or connection of the stamens.

The Orders of the Class Syngenesia are founded on the florets, in
the compound heads, — and are as follows : —

1. Polygamia aequalis, where the florets are all perfect.

2. P superflua, where the central, or disk florets are perfect,

and the ray florets are merely pistillate.

3. P fruslranea, where the disk florets are perfect, and the ray

florets neutral (or vacant).

4. P necessaria, where the disk florets are staminatc, and the

r ay florets pistillate.

PEELIMINAEY DISCOURSES;

5. P segregata, where each floret in th&- head1 has a kind of

involucre of its own — separating it from the others.

The Orders of the Cryptogamia, or 24th Linnaaan Class, have
been already noticed, as being necessarily natural.. By distributing
the Genera, which LINNAEUS placed in Dodecandria, Polyadelphia,.
and Polygamia, among the other Classes, the number of those pri-
mary divisions may be reduced to 21, withoujt any detriment to the
System. The simplicity and elegance of this method — the facility
with which it is learnt, and applied— are considerations which have
made it extensively popular, — especially with young Botanists:
and although it is avowedly artificial',, the fact of its bringing so
many genera into natural groups, is strong evidence that it is based
on the most important organs in the vegetable economy.*

I shall now conclude these desultory Discourses, by an attempt
briefly to indicate the mode in which Plants are classified, and
viewed, under the Natural System. The object proposed by that
System, is "to bring together into groups those plants which most
nearly resemble each other, not in a single and perhaps unimportant
point (as in an artificial classification), but in all essential particu-
lars ; f and to combine the subordinate groups into larger natural
assemblages, and these into still more comprehensive divisions, so
as to embrace the whole vegetable kingdom in a methodical arrange-
ment. All the characters which plants present, that is, all the
points of agreement or difference, are employed in their classifica-
tion ; those which are common to the greatest number of plants
being used for the primary grand divisions;, those less comprehen-
eive for subordinate groups, &c. ; so that the character, or descrip-
tion of each group, when fully given, actually expresses all the
known particulars in which the plants it embraces agree among
themselves, and differ from other groups of the same rank. This

* The most superficial observer cannot fail to be struck with the fact, that the
Sexual System groups together — with comparatively few exceptions — the genera
belonging to the following eminently natural — and some of them eminently
large — families of flowering plants : namely. Cruciferae, Malvaceae, Leguminosae,
Hosaceae, UmbeHiferae, Compos itae, Labiatae,Boraginaceae, Orchidaceae, Cyperaceae,
and Gramineae, — not to mention a number of others, wh ich will occur to the
experienced Botanist, as more or less approximating a natural association.

•{•The Njtiurallt'—s&ys Prof. DE CxyooLLE— arranges or groups together all those
beings which have the greatest number of organs in common, or of similar struc-
ture,— and separates those which possess but a small number of them in common :
whence it results that, while the perfection of an Artificial System consists in
connecting with the character of the Classes the smallest possible number of
ideas, — a Natural Method, on the contrary, is so much the more perfect, as thu
characters of the Classes are expressive of a greater number of ideas,

complete analysis being carried through the system, from the
primary divisions down to the species, it is evident that the study
of a single plant of each group will give a correct general idea
of the structure, habits, and even the sensible properties, of the
whole." — GRAY'S Text-book.

The vegetable kingdom, viewed in reference to the natural
system, is divided primarily into two great SERIES, — a higher one,
called phaenogamous or flowering plants producing proper flowers
(with stamens and pistils), and seeds containing a ready-formed
embryo or young plantlet — and a lower one, called cryptogamous
orflowerless plants, which are reproduced by little cellular analogues
or equivalents of seeds, termed spores, without the agency of proper
flowers.

The higher SERIES (or flowering plants) — which embraces the larger
and more important portion of the vegetable kingdom — is divided
into two Classes, named Exogens, and Endogens. The difference
between these two Classes pervades their whole port and aspect,
and is manifest from their earliest stage of existence. The embryo
of Exogens is provided with a pair of opposite cotyledons (rarely with
more than two — as in some of the Coniferae, or Pine family), — that
of Endogens, with only one,- whence the former have been also
termed Dicotyledonous, and the latter, Monocotyledonous plants. —
There is a remarkable difference, likewise, in their foliage; the
leaves of the Exogens generally having reticulated or netted veins,
and falling off by an articulation, or separable joint, — while the
Endogens have nearly parallel-veined leaves, which are not articu-
lated, but wither on the stem.

The class of Exogens is divided into two Sub- Classes ; the one,
much larger, bearing their seeds in a proper Pericarp, or closed
Seedvessel, and hence called Angiosperms ; the other (containing a
couple of Orders), having the seeds naked, — i. e. borne on an open
scale, or seated in a fleshy disk, — andtherefore called Gymnosperms.

The Subclass of Angiosperms contains so many Orders, that it
has been found convenient to adopt some rather artificial divisions,
based on the character, or absence, of the Corolla. The first
division comprises those exogenous plants, in which the petals of the
flower are all nearly or quite distinct, or separate from each other, —
and are termed polypelalous, or more accurately, dialypetalous
Exogens. The second division is composed of those in which the
petals are more or less completely united by their margins into one
piece — forming a sort of tubular corolla, — and the plants of this
division have been called monopetalous, but more properly gamo-
petalous Exogens.

PRELIMINARY DISCOURSES. XXXV

The third division includes those in which the Corolla (and
occasionally the Calyx, also,) is wanting ; — and the plants of this
division are therefore called apetalous Exogens. A few exceptions,
however, occur in each of these divisions (as in every other arrange-
ment, yet devised — whether natural, or artificial) ; which will be
noticed in the proper places.

The Subclass of Gymnosperms — as already mentioned — consists
of a couple of Orders ; viz. the Coniferae, or Pine Family, — and the
Cycadaceae — a small tropical Order, — in which the pistil is repre-
sented by an open scale, or by a more evident leaf, — or sometimes
entirely wanting ; and the ovules and seeds consequently naked — i. e.
not included in a pericarp.

The above are the principal divisions of the great Class of
Exogenous Plants: But these (as in the other Classes,) are again
sub-divided into Groups, Orders, Suborders, Tribes, Subtribes, Genera,
Subgenera, Species, and Varieties. The Groups comprise kindred
Orders, — while the Orders and Tribes consist of kindred Genera, and
usually derive their names from some well-defined typical Genus
(as Malvaceae, or Rosaceae),- — or some characteristic family feature
(as Umbelliferae, or Leguminbsae).*

The Class of Endogens — partially defined above — does not admit
of so many principal divisions, as the preceding ; but contains a
number of well-characterized Orders and Tribes, — as will be seen in
the following pages.

The second or lower SERIES of plants — called cryptogamous, or
fiowerless — has been divided into three Classes ; in two of which, the
plants have a distinct axis, or definite stem and foliage, — and in the
third, there is no distinction of stem and foliage, but a mere veget-
able expansion — or thallus, so called. The plants of the first of
these cryptogamous Classes, consist of woody and vascular tissue,
and grow only at the summit, — and are, for that reason, termed
Acrogens, or Apex-growers, — embracing the Ferns, and Fern-like
plants. Those of the second Class consist of cellular tissue only ; but,
having a distinct foliage, and acrogenous growth, with somewhat of

* Some of the Orders are so remarkably natural — i. e. the structure and more
obvious features of the plants comprised by them, are so similar, — that it is often
difficult to indicate good and striking characteristics, by which to distinguish the
{/ewera belonging to them. This is especially true of the Families named Oruci-
J'erae, Umbelliferae, and Labiatae: so much so, indeed, that each of those Orders
might be regarded as a comprehensive, and yet tolerably well-defined, Genus. —
This fact will enable the Student to understand why it has been found necessary,
in such families, to seize upon any constant characters — however minute, or
obscure— that may eenre to discriminate between closely allied Tribes and
Genera.

the aspect of the superior plants, they have on that account been
denominated Anophytes, — comprising the Mosses and Hepaticae.

The plants of the third and lowest cryptogamous Class com-
posed of parenchyma alone, or mere cellular masses, or expansions,
without any marked distinction of root, stem, or foliage, — are called
Thallophytes. This Class consists mainly of Lichens, Fungi, and
Algae, or Sea-weeds, — some of which present the simplest forms of
vegetable existence.

"In an exposition of the natural system, some authors (such as
JUSSIEU and ENDLICHER) commence with the lower extremity of
the series, and end with the higher; while others (as DE CANDOLLE)
pursue the opposite course, beginning with the most perfect flower-
ing plants, and concluding with the lowest grade of flowerless
plants. The first mode possesses the advantage of ascending by
successive steps from the simplest to the most complex structure ;
the second, that of passing from the most complete and best under-
stood to the most reduced and least known forms; or, in other
words, from the easiest to the most difficult ; and is therefore the
best plan for the student."*

the youthful reader in the hope, and for the simple purpose, of
Commending to his favor the study of the interesting objects here-
inafter described ; and in the firm belief, moreover, that such study

NATURAL ARRANGEMENT

OP THE

GROUPS AND ORDERS IN THIS WORK.

THE VEGETABLE KINGDOM is arranged, by Prof. A. GRAY in his Botanical Text
Book (which arrangement is here adopted), in two Series or grand Divisions —
known as Phaenogamous or Flowering Plants, and Cryptugamous or Flowerless
Plants. These, again, are subdivided ; and the plants belonging to them are
disposed, according to their structure and affinities, in Classes, Sub-Glasses, Divisions
Groups, Orders, Sub-Orders, Tribes, Sub-Tribes, Genera, Sub-Genera, Species and
Varieties.

The following is a Synoptical View of the general arrangement and grouping of
the Natural Orders, or Families, to which the plants enumerated in this work are
referable ; which, the intelligent reader will perceive, has been derived from the
valuable Text-book, above mentioned. Such a Conspectus, it is believed, may be
satisfactory and useful to the Student,— as affording a comprehensive glance at
the general principles, or basis of the System, upon which the superstructure of
details has been erected. Under this impression it has been here inserted.

SERIES I.

PHAENOG'AMOUS OR FLOWERING
PLANTS.

PLANTS furnished with flowers (essentially consisting of stamens
and pistils], and producing proper seeds.

CLASS I.

EXOGENOUS OR DICOTYLEDONOUS
PLANTS.

STEM consisting of a distinct bark and pith, which are separated
by an interposed layer of woody fibre and vessels, forming wood in
all perennial stems ; increase in diameter effected by the annual
deposition of new layers between the old wood and the bark, which
are arranged in concentric zones, and traversed by medullary rays.
Leaves commonly articulated with the stem, their veins branching
and reticulated. Sepals and petals, when present, more commonly
in fives or fours, and very rarely in threes. Embryo with two or
more cotyledons.

XCii NATURAL ARRANGEMENT.

Hob. Meadows, and pastures. Nat. of Europe. Fl. May. Fr. June, July.

Obs. This foreigner is becoming extensively naturalized, and is
often very abundant in pasture lots. It is considered as very much
of a nuisance, by the owners of meadows along the Brandywine. —
The fleshy bulb is highly acrid ; and, it is said, is often used by
artful beggars, in Europe, to produce ulcers, &c., and thereby excite
sympathy.

Hob. Gardens, and cultivated grounds. Nat. of Europe. Fl. July. Fr. August.

Obs. This introduced plant is usually to be met with in gardens ;
and occasionally finds its way into the grain-fields of thoughtless
people who are in the practice of carrying garden-rubbish into the
barn-yard. In such cases, it threatens to become a nuisance.

TRIBE 5. CIMICIFIPGEAE.

&paU colored, caducous; petals none, or small and flat (staminodia) ; pistils 1 or
several ; fruit baccate, or follicular, 1- 2- or many-seeded. Leaves alternate. Peren-
nial tierbs,

compound, virgate, 6 to 12 inches long, bearing many white flowers. Seeds flatted,
packed horizontally in 2 rows.
Hob. Rich woodlands : common. Fl. June. Fr. Sept.

Obs. The white racemes of this plant, when in flower, are quite
conspicuous in our woodlands. The stem and leaves, when bruised,
have a disagreeable odor. The large root is somewhat mucilaginous
and astringent ; and an infusion of it is quite a popular medicine,
for both man and beast, — without much regard to the nature of the
disease !

Hob. Swamps, and along rivulets : rare. Fl. June. Fr. Sept.

Obs. This delightful little tree, though abundant in the swamps
of New-Castle county, on the south of us, is rare in Chester county.

MAGNOLIACEAE 9

KALM, in his Travels, -written a century since, says — "Both the
Swedes and English call it Beaver tree, because the root of this tree
is the dainty of Beavers, which are caught by its means."

2. M. AcuMiNkTA, L. Leaves oval, shortly acuminate, green

beneath ; petals oblong ; cones cylindric-oblong.

ACUMINATE MAGNOLIA. Cucumber Tree. Mountain Magnolia.

ers bluish-white, with tinges of yellow; petals scarcely expanding. Cones sub-
cylinclric, 3 to 5 or 6 inches long.
Hob. Yards, and lawns : cultivated. Fl June. Fr. Oct.

Obs. This majestic and symmetrical species (a native of our
mountains) is beginning to be appreciated, and introduced here, as
an ornamental shade tree. No one could behold the noble specimens
in the old Marshall Botanic Garden, without feeling its value, in
that respect. Other ornamental species are also cultivated.

long, becoming yellow in autumn; petioles 2 to 3 inches in length. Flowers tulip-
shaped, greenish-yellow, with dashes of reddish-orange. Carpels produced at^ip«x
into a lance-oblong wing, and closely imbricated on the fusiform receptacle.
Sab. Rich woodlands, and fence-rows : common. FL May. Fr. October.

Obs. The wood of this magnificent tree is highly valued in many
branches of the mechanic art, — especially the variety called yellow
poplar, which is generally to be known by its thicker and more
deeply furrowed bark. The bark of the root, and young tree, is a
good aromatic bitter. "Many people," says KALM, "believe its
roots to be as efficacious against the fever as the Jesuit's Bark." —
Persons of taste are beginning to discover, that this, and some
others of our splendid forest trees, are quite as worthy of cultivation,
for shade and ornament, as many of the far-fetched exotics. The
'same may be said, also, of our brilliant native shrubs, — such as the
Kalmias, Azaleas, &c. &c.

scarcely % an inch in length. Flowers solitary, lateral, appearing rather before
the leaves ; petals dark brownish-purple, with tinges of yellow within. Carpels
connate, becoming a 2 or 3-lobed yellowish pulpy berry, — or more usually (by
abortion) a simple ovoid-oblong berry, 2 to 3 inches in length.
Hob. Banks of streams; Schuylkill: not common. Fl. May. Fr. Sept.

Obs. The fruit of this small tree is esculent, and not unpalatable,

Seeds with a fleshy integument, and a solid horny albumen, deep blue at maturity.
Hob. Rich woodlands : frequent. Fl. April. Fr. Aug.

Obs. This curious plant was one of the numerous articles of the
aboriginal materia medica, now fallen into neglect. Though nearly
allied to the Leontice, of Europe, I entirely concur with Prof. A.
GRAY, that it may "very probably resume its generic rank"; and
have accordingly acted upon the suggestion.

Her meads of asphodel, and amaranth bowers,
Where Sleep and Silence guard the soft abodes,
In sullen apathy PAPAVEE nods."

rope— was found (in 1838, since the publication of the preceding
edition), near Downingtown, by Mr. JOSHUA HOOPES. It is easily
propagated, and is now naturalized in several localities in the
County. Being a wholesome Salad, it deserves to be generally in-
troduced into suitable springs and brooks, for table use.

Obs. Few plants have undergone greater modifications, by cul-
ture, than this esculent herb ; and those varieties farthest removed
from the original form, are the most esteemed. Cabbage, in every
form, has always been a general favorite with the Germans; and
from them we have borrowed not only the preparations of the herb,
but their names, — such as Bauer-kraut; and Kohl-Salfit, — which
latter (meaning literally Cabbage Salad,') has been anglicised into
Cole — and even Cold-Slaw!

Obs. This plant is pretty generally naturalized among us, but
not much cultivated. It makes a rather troublesome weed, when
fully introduced. In the West (especially in Ohio), it is extensively
cultivated. The value of its highly acrid seeds, in the hands of the
cook and physician — as a condiment and rubefacient — is well
known.

Obs. Of the Alpine species of this insignificant genus, the grandil-
oquent DARWIN, in his Botanic Garden, sings as follows : —
" Where rears huge Tenerif his azure crest,
Aspiring DRABA builds her eagle nest;
Her pendant eyry icy caves surround,
Where erst Tolcanos mined the rocky ground.
Pleased round the Fair four rival Lords ascend
The shaggy steeps, two menial youths attend.
High in the setting ray the beauty stands,
And her tall shadow waves on distant lands."

Obs. The pungent root of this plant is a favorite condiment, and
one of the most valuable antiscorbutics. The true or common
Scurvy grass, of Europe, is a species of this genus (C. officinalu, L.) ;
but is rarely, if ever, to be met with under culture, here.

valves. Seeds reddish yellow.
Hob. Cultivated grounds. Nat. of Europe. Fl. June. Fr. July.

Obs. This foreigner was formerly frequent among Flax, when
that plant was generally cultivated ; but since that culture has de-
clined, the Camelina has become more rare, within my observation.
I am informed, however, by H. JONES BROOKE, Esq., of Delaware
county, Pennsylvania, that it had recently become a serious nui-
sance, in his wheat fields. Being an annual, the obvious remedy
"Was to prevent it from maturing its seeds ; but, being contempora-
neous with the crops, and mingled with them, its extirpation seemed
a hopeless task. Finding his grounds getting full of this pest, Mr.
BROOKE — with the practical sagacity of an intelligent observer —
adopted a plan which resulted in complete success : namely, keep-
ing the ground ploughed or stirred, for a year or two, so often as
to prevent the ripening of new seeds, and to promote the vegetation
of all the old ones in the soil. Among the vulgar errors of benighted
agriculture, was the belief that this plant was a kind of transmuted
or degenerate Flax, — caused by burning the soil, in clearings.

inches long, at first circinate.

Hob. Swampy springs, on the slaty hills: rare. Fl. July. Fr. Aug.

Obs. The imaginative author of the Botanic Garden thus describes
this curious little plant: —

"Queen of the marsh, imperial DROSERA treads

Rush-fringed banks, and moss-embroidered beds;

Redundant folds of glossy silk surround

Her slender waist, and trail upon the ground;

Five sister-nymphs collect with graceful ease,

Or spread the floating purple to the breeze ;

And five fair youths with duteous love comply

With each soft mandate of her moving eye.

As with sweet grace her snowy neck she bows,

A zone of diamonds trembles round her brows;

Bright shines the silver halo, as she turns ;

And, as she steps, the living lustre burns."

ORDER XV. HYPERICiCEAE.

Herbs, or shrubs, with a limpid or resinous juice; leaves opposite, entire, punctate,
without stipules; flowers regular, hypogynous, polyadelphous ; petals mostly con-

and half long, rather obtuse, with numerous pellucid punctures like perforations.
Eab. Fields and pastures. Nat. of Europe. Fl. June. Fr. July.

Obs. This foreigner is a worthless and rather troublesome weed,
in Chester County. It was formerly supposed to be the cause of
scabs, and cutaneous ulcers, among cattle, — especially white cows,

HYPERICACEAE 29

and horses with white feet and noses. The fact was taken for
granted, by the farmers: But, it must be confessed, that although
the plant continues to be abundant, the disease has nearly, if not
entirely, disappeared. It may be worthy of remark, that in the
year 1842, the St. John's-Wort totally failed to make its appearance
(in this County — and I believe throughout Pennsylvania) ;— even in
fields where it had been most abundant. The succeeding year, it
was quite rare ; but has since become about as common as ever, in
neglected fields. Why a perennial should have been thus affected,
seemed rather mysterious.

Hub. Wheat and Rye fields. Nat. of Europe. Fl. June. Fr. July.

Obs. This foreign weed (specifically named Gitliaao, from its fan-
cied resemblance to " Gith," or Guinea-Pepper), though diligently
rooted out by all neat farmers, obstinately maintains its ground in
our grain fields. The rough black seeds, when abundant among
wheat (and their size makes it difficult to separate them from it),
are injurious to the quality and appearance of the manufactured
flour.

Barrens, Chester County ") to Dr. MUHLEXBERG, who pronounced
it a new species, and proposed to call it C. lanatum. In 1813, he
published it, in his Catalogue, by the name of C. villosum. In 1820,
Prof- D. B. DOUGLASS collected it at Sandusky, Ohio ; and a descrip-
tion (without a name), by Dr. TORRE Y, was published in 1822, in

ORDER XVIII. MALVACEAE.

Herbs, or shrubs (those here described are all herbaceous) ; leaves alternate, stipu-
late ; flowers regular, — the calyx valvate, the corolla convolute, in the bud ; sta-
mens numerous, monadelphous in a column, — the ant/iers 1-celled, reniform; seeds
with little albumen ; embryo curved, the foliaceous cotyledons variously doubled up>
The plants of this family are generally remarkable for their mucilaginous and
demulcent properties ; but the order is pre-eminently distinguished, as containing
the Cotton Plant (Goisypium herbaceum, Z.),— which enters so largely into the
planting^ commercial, and manufacturing concerns of the civilized world.

Hob. Yards, gardens, &c. Nat. of Europe. Fl. May. Fr. Aug.

Obs. This foreigner is extensively naturalized, and a rather trouble-
some weed in gardens. The plant is mucilaginous, — and quite a
popular ingredient in cataplasms, demulcent drinks, &c. The M.
crispa, sylvestris, and moschata, are frequent about gardens ; but are
scarcely naturalized, yet.

MALVACEAE 37

65. AI/THAVEA, L,

Perennial. Stem 2 to 4 feet high, simple. Leaves 2 to 4 inches long ; petioles 1 to
2 inches long. Flowers pale-red, subpaniculate; common peduncles about as long
as the petioles, 3- to 6-flowered.
Hob. Gardens, &c. Nat. of Europe. PL July. Fr. Sept.

Obs. This was formerly much (and is yet, occasionally) cultiva-
ted, for its mucilaginous qualities. The A. rosea, Cavan. or Holly"
hock, is to be seen in almost every garden ; but is scarcely to be
regarded as fully naturalized.

66. IIIBIS'CUS, L.

[An ancient classical name, for one of the mallow tribe.]

6 inches long, erect, 8- or 10-angled, 8- or 10-celled.
Hob. Gardens, and lots. Nat. of India. Fl. Aug. Fr. Sept.

Obs. This is cultivated for the sake of its young pods, or cap-
sules,— which are remarkably mucilaginous, and esteemed by many
persons as an ingredient in soups.

ORDER XIX. TILIACEAE.

Trees, or shrubby plants ; leaves alternate, with deciduous stipules ; flowers axillary,
small; sepals valvate, and petals imbricated, in the bud; stamens somewhat poly-
adelphous ; anthers 2-celled ; seeds albuminous.

This, like the preceding, is a mucilaginous family of plants ; and some of the
species are also remarkable for the texture and strength of their bark. The liber,
or inner bark of the Tilias, separates readily into thin layers, or strips, which are
extensively woven into matting, in the North of Europe ; and the Gunny-bags, of
commerce, are manufactured from the fibrous bark of two species of Corchorus.

(viz. in the N. American species) each parcel adnate, at base, to a
spatulate petaloid scale (staminodium), opposite the real petals. —
Ovary 5-celled; style single. Fruit a coriaceous or woody globose
nut, 1 -celled, 1- or 2-seeded. Trees; flowers in pendulous cymes,
with the lower half of the common peduncle adnate to the lower half
of a long membrano-foliaceous bract.

1 to 2 inches in length. Flowers ochroleucous.
Hob. Banks of streams ; Brandywine : not common. Fl. Last of June. Fr. Sept.

Obs. The wood of this tree affords a good material for the manu-
facture of various domestic utensils. It is sometimes cultivated for
shade ; but the branches are not so symmetrical as those of the Eu-
ropean species. Neither of them, however (mejudice), is equal to
the Sugar Maple, or Horse Chestnut, as ornamental shade trees.

ORDER XX. LINACEAE.

Herbs; leaves alternate, opposite, or verticillate, without stipules; flowers regular,
hypogynous, all the parts in fives; calyx imbricated, petals convolute; stamens
united into a ring at base; capsule globose, with twice as many cells as styles; ceUs
1-eeeded; seeds fleshy and oily, with little or no albumen.
An Order pretty much limited to the important genus which is its type.

Sab. Fields. Nat. of Europe. Fl. June. Fr. July.

Obs. This plant — once considered so indispensable among the
crops of our farmers — is now rarely cultivated. The Cotton-plant,
of the South, has nearly banished the Flax from this region ; though
some attempts are now being made, among Manufacturers, to in-
crease the use of Flax, by improving the manipulations of its fibres.
The Farmers, however, will not be anxious to resume the culture ;
for the crop is one which involves a good deal of disagreeable labor, —
and is, moreover, believed to be injurious to the soil: an opinion as
old as the time of VIRGIL — who says :

" Urit enim Lini campum Seges, urit avenae." — Georg. 1. 71.
or, as rendered by SOTHEBY,

" Oats and the Flaxen Harvest burn the ground."
Doctor DARWIN refers to the Flax, in the following strains : —

" Inventress of the Woof, fair LINA flings

The flying shuttle through the dancing strings;

Inlays the broider'd weft with flowery dyes,

Quick beat the reeds, the pedals fall and rise:

Slow from the beam the lengths of warp unwind,

And dance and nod the massy weights behind.

Taught by her labors, from the fertile soil

Immortal Isis clothed the banks of Nile ;

And fair ARACHNE with her rival loom

Found, undeserved, a melancholy doom."

"Isiswas said to have invented spinning and weaving,— mankind before that
time being clothed with the skins of animals. The fable of ARACHNE was to com-
pliment this new art of spinning and weaving, supposed to surpass in fineness the
web of the spider."

The seeds of this plant — beside yielding a most valuable oil —
afford one of the best mucilaginous drinks, for coughs, and dysen-
teric affections.

ORDER XXL GERANIACEAE.

Herbs, or suffruticose plants, with tumid nodes ; leaves mostly opposite and palmate,
lobed, stipulate; flowers symmetrical, hypogynous, pentamerous; sepals imbricated ;
petals convolute; stamens 10, slightly monadelphous at base, the alternate ones
shorter ; pistils 5, adhering to a central prolonged axis, from which they separate
at maturity by curving up from the base ; seeds solitary, without albumen.

This Order comprises, amongst others, the numerous and favorite plants, so
much cultivated under the name of " Geraniums," — though they now belong to
the genus Pelargonium.

cauline half an inch to 3 inches in length. Flowers pale red, veined, small, sub-
fasciculate.
Hob. Low grounds; along Brandy wine : not common. Fl. May. Fr. July.

ORDER XXII. OXALIDACEAE.

Herbs, with sour juice; leaves alternate, compound, mostly without stipules; flmvers
regular, nearly as in Geranium,— but the styles separate, and the fruit a 5-celled
several-seeded capsule; embryo straight, in thin fleshy albumen.

[Gr. Oxys, sharp, or sour; from the quality of the plants.]
Petals withering after expansion. Capsule membranaceous, oblong,
pentagonal, opening at the angles. Seeds pendulous from the axis,
their outer coat loose and separating. Leaves mostly composed of
8 obcordate leaflets, — the radical ones stipulate.

sepals callous at apex.

VIOLET OXALIS. Violet Wood-Sorrel.

Perennial. Leaves radical, trifoliolate; leaflets about half an inch long, and
•wider than long ; common petioles 3 to 6 inches long. Scapes 4 to 6 or 8 inches high ,

long, cymosely 3- to 10-flowered. Flowers yellow.
Hob. Fields, and woodlands : common. Fl. May. Fr. July.

Obs. This is a very variable plant — in size, habit, and pubescence ;
but it is difficult to designate good characters for more than one
species, among all the varieties.

ORDER XXIII. BALSAMINACEAE.

Herbs; stems succulent, sub-pellucid, and gorged with a watery juice; leaves usually

BALSAMINACEAB 41

alternate, simple, without stipules; flowers very irregular; stamens 5, the antfiers
introrse, connivent and sometimes coherent; capsule, bursting elastically ; seed*
•without albumen.

L.

[Latin ; alluding to the sudden bursting of the ripe pod, when touched.]
Calyx and corolla colored nearly alike : Sepals apparently 4, — the
2 upper ones being united almost to the apex — the lower one
largest, forming a spurred sac, at base. Petals 4, united in pairs,
forming one unequally 2-lobed petal on each side. Ovary 5-celled;
stigma sessile. Capsule with evanescent partitions, 6-valved, — the
valves incurving elastically from apex to base, and scattering the
seeds. Annuals.

1. 1. l>5i 1 1 i d a , Nutt. Leaves oblong-ovate, rather acute ; sac di-
lated, broader than long, obtusely conic, with a short recurved spur.

low, sparingly dotted with brownish-red ; spur about % of an inch long. >
Hob. Moist, shaded grounds : frequent. Fl. July. Fr. Aug.

"2. I. fViIvil, Nutt. Leaves rhombic- ovate, rather obtuse; sac
longer than broad, acutely conic, with a longish recurved spur.
TAWNY IMPATIENS. Spotted Snap-weed.

Stem 2 to 4 feet high, branched. Leaves 1 to 3 or 4 inches long. Peduncles
about an inch long, usually 2- or 3-flowered. Flowers orange-color, with numerous
reddish-brown spots ; spur about half an inch long.
Hob. Moist, shaded grounds : common. Fl. July. Fr, Aug.

Obs. Our two species were formerly regarded as one, and referred
to the /. noli-tangere, of Europe, — to which they are nearly allied.
The /. jBalsamina, L. called "Lady's Slippers" — a native of India —
is abundant, and almost naturalized, in every garden. The follow-
ing fanciful lines, from DARWIN, probably have reference to the
European species, — but may apply to all: —

"With fierce distracted eye IMPATIENS stands,
Swells her pale cheeks, and brandishes her hands,
"With rage and hate the astonished groves alarms,
And hurls her infants from her frantic arms."

ORDER XXIV. TROPAEOLACEAE.

Herbs ; stems straggling or twining, fleshy, with a pungent watery juice ; leaves
alternate, peltate, with radiating nerves, and without stipules ; flowers irregular,
large, on long axillary peduncles; fruit 3-lobed, or of 3 connate, 1-seeded, inde-
hiscent carpels ; seeds without albumen,

V'2. TROPAEVOMJM , L.

(said to be perennial in its native country) ; smooth. Stem 3 to 6 or 8
feet long, branching and climbing. Leaves 2 to 3 inches in diameter ; petioles 3 to 6
inches long. Peduncles 1-flowered, mostly longer than the petioles. Flowers pale
yellowish- or reddish-orange, with dark purple stripes and spots. Carpels sulcate,
fleshy, finally subcoriaceous.
Hob. Gardens. Nat. of Peru. Fl. June. Fr. Aug.

Obs. This is cultivated, — both for show, and for the young fruit,
•which is prepared as a condiment, and affords a tolerable substitute
for capers.

ORDER XXV. LIMNANTHACEAE.

Herbs; stems fleshy; leaves alternate, pinnately dissected, without stipules; flowers
regular, of 3 or 5 parts; sepals valvate, and petals convolute, in the bud; stamens
twice their number; fruit of 3 to 5 fleshy connate 1-seeded akenes; styles united;
seeds without albumen.

73. FL,OVERKEA, Wittd.

[Dedicated to Henry Gustavus Floerke, a German Botanist.]
Sepals 3, connected at base, persistent. Petals 3, shorter than the
sepals. Ovaries 3, opposite the sepals, cohering at base. Style
central; stigmas 8. Akenes utricular, tuberculate, often only 1 or 2.

1. F. prose rpiiiacoitles, Willd. Glabrous; stem terete;

PROSERPINACA-LIKE FLOERKEA.

Annual. Stem 4 to 10 or 12 inches long, nearly simple, flaccid, finally procum-
bent. Leaflets, or segments, half an inch to an inch long ; common petioles 1 to 3
inches in length. Peduncles axillary, finally about an inch long, 1-flowered.—
Petals white, alternate with, and scarcely half as long as the sepals.
Hob. Miry, shaded places : frequent. Fl. April Fr. May.

ORDER XXVI. XANTHOXYLACEAE.

Trees, or shrubs ; Uaves mostly alternate, compound, without stipules, or armed
with stipular prickles ; ./fotwers'polygamo-dioicous, regular, small: stamens as many,
or twice as many, as the sepals ; ovaries distinct, or 2-celled ; fruit various, — bac-
cate, capsular, or samaroid ; seeds 1 or 2 in each carpel, albuminous.

74. AIL-A^THUS. Desf.

[Formed from Atlanta,— the name it bears in its native country.]
Calyx 5-toothed. Petals 5, inserted with the 10 stamens, under a
hypogynous disk. Carpels 3 to 5, samaroid, tumid in the centre,
1 -celled, 1-seeded. Stigmas capitate, radiately 5-lobed.

Stem 30 to 60 feet, or more, in height, much branched, but never ramifying dur-
ing growth. Leaflets 3 to 5 inches long, numerous (15 to 20 pairs, and a terminal
one). Flowers pale greenish-yellow, in terminal thyrsoid panicles.
Hob. Streets, and about houses. Nat. of China. Fl. June. Fr. Sept.

Obs. This is not an ungraceful tree in its habit, — but a disagree-
able one in its odor. It is also exceedingly troublesome in sending

' XANTHOXYLACEAK 43

np countless suckers from its wide-spreading roots. It was intro-
duced as a Shade tree, about the year 1820 ; but will scarcely main-
tain its position as such. I learn from WM. JACKSON, Esqr., of
Harmony Grove, in this County, that the XANTHOX'YLON AMEBI-
C\NUM, Mill. — (a prickly Shrub, which is the type of this Order), —
has escaped from the gardens, and is becoming naturalized^, sev-
eral places in that vicinity.

ORDER XXVII. ANACARDIA^CEAE.

Shrubs, or trees; with a resinous, or milky, acrid juice; leaves alternate, mostly
compound, without stipules; flowers regular, pentandrous, small, often polygamo-
dioicous ; ovary (by abortion) 1-celled, and 1-ovuled, but with three styles or stig"
mas ; seeds without albumen.

In the tropical regions, this Family presents plants of much interest : — such as
that which yields the celebrated Mango fruit (Mangifera Indica, L.)— the Cashew
JVlrf (Anacardium occidentals, L.) — and the Pistacia Nut (Pistacia vera, L.~), — with
others, which afford various kinds of Lacquer, and Varnish.

75. RHITS', L.

[The ancient Greek and Latin name of the genus.]

Sepals 5, connected at base, persistent. Petals 5, inserted with the
stamens on, or under, the edge of a flatted disk. Fruit small, a sort
of dry drupe. Polygamo-dioicous Shrubs ; common petioles enlarged
at base, covering the buds of the ensuing year.

f Leaves odd-pinnate. * Young branches densely villous.

1. R. ty plii ii a, L. Leaflets oblong-lanceolate, acutely serrate,
pale or glaucous beneath.

TYPHA-LIKE RHUS. Staghorn Sumach.

Juice milky. Stem 15 to 20 or 30 feet high, with spreading branches above.—
Leaflets 2 to 4 inches long, 8 to 12 or 15 pairs and a terminal one. Flowers yel-
lowish-green, in terminal thyrsoid panicles, — the fertile ones about 6 inches long,
very dense, oblong and nearly cylindrical ; fruit densely clothed with a purple
pubescence, which is sharply acid.
Sab. Woods, and banks of streams; Schuylkill: not common. Fl. June. Fr. Sept.

Obs. This is the largest and handsomest species, indigenous to
the County. The fine purple clusters of fruit, on the fertile plant,
render it quite an ornamental little tree ; and when planted in the
yards and public squares of our cities, it affords an almost literal
exemplification of the much-admired Khus in urbe ! Its roots, how-
ever, are rather troublesome, in sending up suckers.

* * Young branches downy-pubescent.

2. R. copallina, L. Common petiole winged ; leaflets oblong
or ovate-lanceolate, nearly entire.

COPAL RHUS. Dwarf Sumach.

Juice resinous. Stem 3 to 6 or 8 feet high, branched. Leaflets 1 to 3 inches long,
usually 4 or 5 pairs with a terminal one, subcoriaceous. Flowers yellowish-green,
in terminal thyrsoid panicles. Fruit densely pubescent, finally dark purple and acid.
Hob. Dry, slaty bills : frequent. Fl. July. Fr. October.
* * * Young branches glabrous.

3. R. gliYbra, L. Leaflets lance-oblong, acuminate, serrate,
whitish beneath.

44 DIALYPETALOUS EXOGENS

GLABROUS RHUS. Common Sumach. Smooth Sumach.

Juice, copiously milky. Stem 3 to 8 or 10 feet high, irregularly branched;
branches stout, with a large pith. Leaflets 2 to 3 or 4 inches long, 10 to 15 pairs,
with a terminal one, becoming crimson in autumn. Flowers yellowish-green, in
dense ovoid terminal panicles. Fruit densely villous, finally bright purple, and
sharply acid.
Hob. Old fields; fence-rows, &c.: common. Fl. June. Fr. Sept.

4. R. veneiiata, DC. Leaflets obovate-oblong, abruptly acu-
minate, the margin very entire and slightly revolute.
POISONOUS RHUS. Poison Sumach. Swamp Sumach.

Juice resinous, Stem 8 to 12 or 15 feet high, branching above. Leaflets 2 to 3
inches long, 4 to 6 pairs, with a terminal one. Flowers greenish, in subterminal
and axillary panicles. Fruit smooth and shining, pale yellowish-green, larger
than in any of the preceding.
Hob. Swampy rivulets : not very common. Fl. June. Fr. Sept.

Obs. This species is very poisonous to many persons. It was
formerly (but erroneously) supposed to be identical with the varnish
tree, of Japan.

f f Leaves trifoliolate.

5. R. ToxiCOdendron, L. Stem erect, or climbing by radi-
cles; leaflets obliquely ovate or rhomboid, acuminate, entire or
angularly dentate.

R. radicans. L. $ FL Cestr*. ed. 2.
POISON-TREE RHUS. Poison- Vine. Poison-Ivy.

Juice resinous. Stem, in the erect variety, 2 to 5 or 6 feet high, with leaflets larger
and variously toothed or lobed ; in the climbing variety, stem 8 or 10 to 30 or 40 feet
long, branching, adhering to trees, fences, and other objects, by means of numer-
ous radicating processes; the leaflets 3 to 5 or 6 inches long, more commonly entire ;
common pttioles 3 to 6 inches in length. Flowers yellowish-green, in slender race-
mose axillary panicles. Fruit dry, smooth and shining, pale brown.
Hob. Woods, fence-rows, &c.: frequent. Fl. May. Fr. Sept.

Obs. The climbing variety (formerly regarded as a distinct species,
and named R. radicans,] is much the most common, here: but some
fine specimens of the erect variety were collected in the South
Western part of the County, in 1841, by Mr. JOHN M'MiNN. They
are both poisonous, to some persons.

ORDER XXVIII. ACERA^CEAE.

Trees, yielding a sweet sap; leaves opposite, without stipules; flowers polygamo-
dioicous, regular but often apetalous or unsymmetrical ; fruit a pair of more or
less diverging separable 1-seeded samaras, winged at summit, with the outer margin
'thicker and obtuse; seeds nearly without albumen.

?6. ACER, L.

[The ancient classical name of the maple.]

Sepals 5, connected at base. Petals 5, or often none. Stamens 5 to
.8. Styles 2, united ; ovary on a glandular-lobed disk.
- f Flowers in pendulous racemes, or corymbs, appearing with the leaves. * Petals 5.

1. A. PSETJDO-PLATANUS, L. Leaves cordate at base, 5-lobed, une-
qually dentate; flowers in terminal pendulous racemes; fruit
diverging.

ACERACKAB 45

FALSE-PLATANUS ACEE. Sycamore. Greater Maple.

A large tree, when full grown. Leaves 4 to 6 inches long, on petioles about the
same length. Racemes ahout 6 inches long; rachis and filaments hairy ; flowers
yellowish-green, the sepals and petals nearly alike; fruit smooth.
Hub. Streets, and yards. Nat. of Europe. Fl. April. Fr.

Obs. This has been introduced, latterly, as an ornamental shade
tree ; but I consider our own Sugar Maple, and the Norway Maple,
as decidedly preferable, notwithstanding COWPER'S lines:

" nor unnoted pass

The Sycamore, capricious in attire,

Now green, now tawny, and, ere autumn yet

Have chang'd the woods, in scarlet honors bright."

Both this and the Plane tree (Platanus), are vulgarly called Syca-
more, in our language ; but ivhy, is not apparent. The true "Syca-
more"— (perhaps the Tree which ZACCIIEUS climbed) — is a species
of Fig-tree (Ficus Sycomorus, L;).

jj. A. pLATANofcES, L. Lactescent ; leaves broadly cordate, 5-
lobed, coarsely dentate ; flowers somewhat corymbose ; fruit divari-
cate, smooth.
PLATANUS-LIKE ACER. Norway Maple.

A large tree, when full grown. Leaves 4 to 6 inches in length, and rather wider
than long, deep shining green ; petioles about as long as the leaves, when broken
exsuding a milky juice! Flowers pale greenish-yellow, in loose, terminal, and
somewhat pendulous corymbs. Samaras remarkably divaricate, glabrous.
Hob. Streets, &c. Nat. of Europe. Fl. April. Fr. ' f\ '

Obs. This tree has been but recently introduced ; yet it promises
to become one of our most desirable shade trees. Its foliage is re-
markably fine, and abundant, continuing gre.en longer than most
other species ; and it is' said that its milky juice prevents the rav-
ages of insects.

* * Petals none.

3. A. sac c* liar i nil in, Wangenh. Leaves broad, palmately 3-
to 5-lobed, the lobes acuminate, coarsely sinuate-dentate; flowers
pendulous on long villous fasciculate pedicels ; fruit slightly diverg-
ing, turgid, smooth.
SACCHARINE ACER. Sugar Maple.

Stem 60 to 80 feet, or more, in height. Leaves 3 to 5 inches long, and about as
wide as long, becoming golden-yellow in autumn ; petioles 2 to 6 or 8 inches in
length. Flowers pale greenish-yellow, truncate and cup-like, the border fringed
with long hairs. Fruit ovoid at base, nearly parallel, rather short.
Hob. Rich woodlands; along streams: rare. Fl. April. Fr. Sept.

Obs. This is one of the most valuable and interesting of our rat-'
tive forest trees, — especially in the North and West — whercits sap,
in early spring, yields an immense quantity of Sugar and Syrup. —
The beautiful wood, known as Bird's-eye Maple — so much admired
in cabinet work — is believed to be aiforded by this species. The
tree is also much cultivated, and deservedly admired, as an orna-
mental shade tree. The A. nigrum, of MX. called Black Maple, seems
now to be regarded as a mere variety of the A. saccharinum. . Its
leaves, however, are usually larger and of a darker green, thicker,
and somewhat coriaceous in texture. It makes even a finer shade

tree than the common variety, and is cultivated for that purpose, in
our villages, — though rarely met with in a wild state, here. It is
said to be more common than the other, at the South.

lobed, with the sinuses acute; ovaries densely tomentose; fruit
very large, — one samara often abortive.

A. eriocarpum. MX. § Fl. Cestr. ed. 2. p. 245.
WOOLLY-FRUITED ACER. Silver-leaved Maple. White Maple.

Stem 30 to 50 or 60 feet high, much and widely branching ; the young branches
virgate and rather drooping. Leaves 3 to 6 inches long, very glaucous or bluish-
white beneath; petioles 2 to 6 inches long. Flowers pale green, in fascicles mostly
of fives or sevens, on short pedicels ; calyx a crenately truncate cup. Samara,
when mature, 2 to near 3 inches long, somewhat resembling the wing of a huge
grasshopper.
Hob. Banks of rivers; Schuylkill: rare. Fl. April. Fr. May.

Obs. This has been extensively cultivated as a shade tree, of late, —
and it has the merit of easy culture, and rapid growth ; but it is
decidedly inferior (me judice] to both the Norway, and the Sugar
Maple.

** Petals 5.

5, A. rub rum, L. Leaves mostly 3-lobed, subcordate at base,
lobes acute, unequally incised-dentate ; ovaries smooth.

RED ACER. Red Maple. Swamp Maple.

Stem 30 to 60 or 80 feet high, branched, the young branches purplish. Leaves 2
to 4 inches long, glaucous beneath ; petioles 1 or 2 to 5 inches long. Flowers bright
purple — or often yellowish-tawny — on longish pedicels.
Hob. Moist, low grounds : common. Fl. March. Fr. Sept.

Obs. The variety with tawny flowers (first noticed, I believe, by
HUMPHRY MARSHALL), is quite frequent in Chester County, — ami
those flowers are generally sterile (staminate) ; while the purple
flowers, so far as I have observed, are constantly perfect and fertile.
The wood of this species — especially that sort known as Curled
Maple — is much esteemed in the manufacture of household furniture.

ACER-LIKE NEGUNDO. Box-Elder. Ash-leaved Maple.

Stem 20 to 30 or 40 feet high, branched ; young branches with a yellowish-green
bark. Leaflets mostly 3, sometimes odd-pinnate in fives, 3 to 5 inches long ; com-
mon petioles 3 or 4 inches in length. Flowers yellowish-green, from lateral buds ;
ovaries hirsute ; fruit diverging.
Hob. Low grounds; along Brandy wine : not common. Fl. April. Fr. Sept.

SAP1XDACEAE 47

Obs. This little tree is certainly distinct, in habit, from the gen-
erality of Maples, — and seems to be finally separated from them, by
modern Botanists; but, if a tree is to be "known by its fruit," this
one will always be liable to be taken, or mistaken, for an Acer.

ORDER XXIX. SAPINDA^CEAE.

Mostly trees, or shrubs; leaves opposite, or alternate, mostly compound, without
stipules ; flowers unsyinmetrical ; ovary 3-celled ; fruit capsular, or baccate ; seeds
without albumen.

cence. Seed large, globose, with a smooth reddish-brown coat, and
broad paler hilum.

1. M. HIPPOCASTANUM, L. Leaflets in sevens, obovate-cuneate,
acute, dentate ; petals five ; fruit echinate.
HORSE-CHESTNUT AESCULUS. Horse-Chestnut.

Stem 30 to 50 or 60 feet high, with opposite symmetrical rather erect branches;
young branches stout, never ramifying the same season — each year's growth being
a definite development from the large buds, and effected rapidly within a few
weeks. Leaflets sessile, 4 to 6 or 8 inches long, penninerved ; common petiole 4 to 8
inches long. Flowers white, with red spots, in large erect terminal thyrsoid
panicles.
Hob. Yards, and streets : cultivated. Fl. May. Fr. October. t

Obs. This ornamental tree (a native of Northern India) is only
now beginning to be appreciated, and to be introduced, here. In-
deed, it is marvellous to reflect, how inconsiderate our people have
been, until quite recently, on the subject of providing Shade trees, as
a shelter from the fervid glare of our Summer's sun. It is to be
hoped that owe posterity may be able to say, with more truth than
we can —

" Our fathers knew the value of a screen

From sultry suns; and in their shaded walks

And long protracted bowers, enjoyed at noon

The gloom and coolness of declining day."

There are several native species, in the Southern and Western
States, where they bear the name of Buck-eye, from a resemblance of
the seeds to the eye of that animal. These native trees, by reason
of their abundance, have become the popular emblem of Ohio —
which is known throughout the Union by the sobriquet of the "Buck-
eye State."

ORDER XXX. CELASTRACEAE.

Smatt trees, or shrubs; leaves alternate, or opposite, compound, or simple, with

ular, small (sometimes apetalous) ; stamens as many as the valvate sepals, alternate
with them and opposite the petals; fruity capsule, or drupe, with 1-seeded cells;
seeds not arillate; embryo in fleshy albumen.

82. CEAWOVTHIIS, L.

[An ancient Greek name; applied to this genus.]

herent to the fruit. Petals cucullate, on slender claws. Capsule
3-lobed, splitting into 3 carpels, which open on the inner side, at
maturity. Shrubs, with the small flowers in an oblong terminal
thyrsus.

to 4 inches long, on short petioles. Flowers white, numerous, thyrsoid, in cymose
fascicles. Seeds rather large, oval, smooth and shining.
Hob. Woodlands, and thickets : frequent. FL June. Fr. Sept.

Obs. The Whigs, in the war of Independence, who were accus-
tomed to drinking Tea, substituted the leaves of this shrub for the
Chinese sorts, — which had become odiously associated with the
tyrannous attempts of the mother country to tax the Colonies.

ORDER XXXII. YITACEAE.

SliruJJby runners, usually with a loose, stringy, dark-brown bark,-^climbing by
tendrils which are opposite the leaves ; leaves alternate, simple and palmate-veined,
or compound, with deciduous stipules* flowers regular, small, mostly in compound
racemes, opposite the leaves ; petals 4 or 5, valvate, caducous ; stamens as many as
.IB petals, and opposite them; fruit a 2-celled 4-eeeded berry; seeds bony; embryo
minute, at the base of hard albumen.

83. TlTTiS, L.

[The ancient Latin name of the Vine.]
Calyx obsoletely 5-toothed, lined with a perigynous disk. Petals

0, cohering at apex, speedily pushed off by the stamens. Stigma
sessile. American species often potygamo-dioicous ; flowers greenish.

tate, glabrous, or tomentose ; fruit of various sizes and colors.
WINE-PEODUCING Vins. Wine-Grape. Foreign Grape, &c.

50 DIALYPETALOUS EXOGENS

Stem 10 to 20 feet, or more, in length (usually kept short by pruning). Leavet
more or less lobed, generally rather smaller than in our native species. Berries
globose, oblong, or obovoid, dark blue, amber-color, or greenish-white.
Hal). Gardens, and Graperies. Nat. of Asia. Fl. June. Fr. Aug. Sept.

Obs. An almost incredible number of varieties, of this species,
have been produced by long culture. It is said, there are about
1400 in the Vineries of France. The Currants of commerce (Cor-
inths, or Grapes of Corinth) — often called Zante Currants — are be-
lieved to be a small-fruited and nearly seedless variety, — or perhaps
a distinct yet closely allied species. It seems now to be agreed, on
all hands, that in our climate, the only mode of securing a crop of
foreign Grapes, is to cultivate them under glass. In that way, the
delicious fruit may almost certain^ be obtained.

f f Flowers oftenpolygamo-diaicous (Native species).

2. V. Labrusca, L. Reaves roundish-cordate, somewhat 3-
lobed, densely tomentose beneath ; racemes simple ; berries large.
Fox-Grape (of the Northern States; not of Virginia).

Stem 15 to 20 or 30 feet long, straggling over bushes and small trees; branchlets
lanuginous. Leaves 4 to 6 inches in length, — the tomentum beneath persistent,
inclining to russet, or tawny ; petides 2 to 4 inches long. Flowers yellowish-green,
in rather short racemes. Berries globose, about half an inch in diameter, varying
at maturity from black to amber color, and sometimes greenish-white ; of a strong
musky or rancid flavor.
Hob. Moist thickets, along streams : frequent. Fl. June. Fr. Sept.

Obs. This gi-ape is believed to be the original of those cultivated
varieties (some of them possibly hybrids) known as Isabella, Schuyl-
kill, Raccoon, Catawba, Alexander's, Tasker's, and Blond's grape. —
They are all decided improvements upon the wild fruit ; and suc-
ceed much better, in this climate, than any of the foreign ones. The
Catawba grape, in particular, has yielded wine of a superior quality,
in Ohio, — and is well worthy of culture as a table grape.

3. V. aestivalis, MX. Leaves broadly cordate, often 3- to 5-
lobed, or sinuate-palmate, loosely tomentose beneath; racemes
densely compound ; berries small.

SUMMER VITIS. Little Grape. Summer Grape.

I ' -Stem 20 to 40, sometimes 60 feet, or more, in length, often climbing high trees. —
'Leaves 4 to 8 inches long, with a loose cobwjeb-like russet pubescence beneath,
" • *vhen young, more hirsute, — sometimes smoothish when older ; petioles 2 to 4
' inches long, Flowers greenish, often umbellulate in the longish compound ra-
cemes. Berries scarcely half the size of the preceding, deep blue or blueish-black,
and covered with a glaucous powder, when mature.
Hab. Woods, thickets, &c.: frequent. Fl. June. Fr. Octo.

Obs. The fruit of this, when fully mature, is of a sprightly acid
and agreeable flavor, — quite a favorite with those who are fond of
pastry Tarts; though the nut-like seeds are rather objectionable. —
Some of the varieties bear larger berries, which might probably be-
come more valuable under culture.

4. V. COrdifolia, MX. Leaves cordate, acuminate, incised-
dentate, smooth on both sides ; racemes slender, loosely compound ;
berries small.

VITACEAB 51

HEART-LEAVED VITIS. Chicken Grape. Winter Grape.

Stem 10 to 20 feet long, climbing and spreading over bushes. Leaves 2 to 6 inches
long, smooth and a little shining, the nerves beneath pubescent; petioles 2 to 5
inches long. Flowers greenish, in loose racemes, which often have long abortive
branches at base, retrograding into tendrils. Fruit small, greenish amber color, or
sometimes nearly black, when mature, very acerb.

Hob. Thickets, fence-rows, &c.: frequent. FL June. Fr. NOT.
Obs. This was mistaken for the V. vulpina, of Linn, until Mr.
ELLIOTT suggested that the true original Fox Grape was most prob-
ably what MICHAUX named V. rotundifolia ; and which is known in
Virginia, and further South, by the various names of Fox Grape,
Bull, or Bullet Grape, Muscadine, and Scuppernong Grape.

yellowish-green, umbellulate in compound cymes. Berries blueish-black ; pedun-
cles crimson.

lube, — the middle or lower one keel-shaped, often crested. Capsule
compressed contrary to the narrow septum, loculicidal. Seeds with
an arillus-like caruncle, or variously shaped appendage at the
hilum.(o,)

This vast family— comprising upwards of 400 Genera— is as important as it
is comprehensive. Among the remarkable plants (or products) belonging to the
Order, and not here described, may be mentioned— on account of their value, beauty,
or other characteristic — the Loffwood (Haematoxylon Campechianum, L.) — the In-
digo plant (Indigofera tinctoria, L.) — -the Braziletto or Brazil-wood (Caesalpinia Bra-

Obs. This is sometimes cultivated for the seeds, — which are said
to be a tolerable substitute for Coffee. The seeds are much used,
as food for horses, &c. in India, — being very abundant (as I recol-
lect to have seen it) in the Bazaars, at Calcutta, under the name of
"Gram." This Vetch is the "Hamoos Pea" which is announced as
a novelty, or great curiosity (discovered among the Arabs), in
LYNCH'S Expedition to the Dead Sea ; though it has been familiarly
known in the gardens, throughout the civilized world, ever since
the days of TOURNEFORT — if not of HOMER! So much, for the
penny- wise policy of sending out Exploring Expeditions unaccompa-
nied by competent Naturalists.

Obs. This is a most valuable plant, — and is diligently cultivated
by all good farmers. It is also extensively naturalized. In con-
junction with the Grasses — especially with Timothy (Phleum pratense,
L-.} — it makes first-rate hay ; though, by itself, it is rather indiffer-
ent pasture. It was introduced into general cultivation, in Chester
County, near the close of the last century ; but it is stated, in WAT-
SON'S Annals, that JOHN BARTRAM had fields of it, prior to the
American Revolution. Authors differ on the question, whether the
plant is perennial, or biennial. Certain it is, that a large portion of
that under culture dies at the end of the second year: but my
friend, JOSHUA HOOPES, assures me, he has ascertained that the
plant will live more than two years. I have met with a number of
instances, in which the usually gamopetalous corolla was substituted
Tdj.five distinct, green leaflets, — with other modifications of the flower,
which finely illustrated GOETHE'S theory of retrograde metamorphosis.

duced plant. JONATHAN DICKINSON, writing from Philadelphia, in
1719, (fide WATSON'S Annals,) says, "the White Clover already tinges
the roads as a natural production." KALM, in 1748, spoke of it as
being abundant, in Eastern Pennsylvania. Its flowers are a favorite
resort of the Honey Bee; and the plant is esteemed, as affording
an excellent pasture, in this region, — though Mr. ELLIOTT speaks
unfavorably of it, in the South.

Obs. This little tree is admired, in early spring, for its clusters
of small flowers, which clothe the branches in purple before the
leaves appear. The limbs are very liable to split oif, and disfigure
the tree, — otherwise it would well deserve a place in all groups of
ornamental shrubbery.

Hob. Low grounds ; along streams : frequent. Fl. Aug. Fr. Octo.

06s. The leav es of this rather showy species afford, it is said, a
tolerable substitute for the Senna of the shops, — which is another
species of the same genus. Doctor DARWIN, in his Botanic Gar-
den, probably refers to this one, as follows: —

"Where vast Ontario rolls his brineless tides,

And feeds the trackless forests on his sides,

Fair CASSIA, trembling, hears the howling woods,

And trusts her tawny children to the floods.

Tinctured with gold, while ten fond brothers stand,

And guard the beauty on her native land ;

Soft breathes the gale, the current gently moves.

And bears to Norway's coasts her infant loves."

"This," he adds, "is one of the American fruits which are annually thrown on
the coasts of Norway ; and are frequently in so recent a state as to vegetate, when
properly taken care of."

•with a depressed or cup-like gland on the upper side. Flowers deep bright yel-
low (usually with purple spots at base), in lateral subsessile fascicles above the
axils of the leaves,— often in pairs, sometimes 3 or 4. Legumes about 2 inches
long, hairy along the sutures.
Hob. Hills, near Pugh-town : rare. Fl. July. Fr. Sept.

Obs. In a paper, read before the American Philosophical Society,
May 2, 1788, and published in the 3rd volume of their Transactions,
Dr. GEEENWAY, of Virginia, speaks favorably of this plant as a
means of recruiting worn out lands, by its decomposition in the
soil, — though he considers the common corn-field Pea as preferable ;
and I have no doubt that the red Clover (Trifolium pratense), properly
managed, is more eligible than either.

greenish white. Legumes 6 or 8 inches long, and 1 or 2 inches wide, somewhat
falcate ; seeds large, a little compressed, nearly orbicular.
Hob. Yards, and streets. Fl, May. Fr. Octo.

Obs. This fine tree has been introduced from the West ; and al-
though not equal to some others, as a shade tree, is worthy of a
place in all ornamental plantations. It was for a considerable time
supposed to be identical with, or nearly allied to, the Bonduc, or
Nickar-tree (Guilandina Bonduc, L.}, of the Indies.

ORDER XXXV. ROSATEAE.

Trees, shrubs, or herbs ; leaves alternate, stipulate ; flowers regular; stamens dis-
tinct, inserted on the calyx, mostly numerous ; pistils 1 to many, free, or combined
with the calyx-tube; seeds 1 or few in each ovary, without albumen; radicle
straight.

This Order is remarkable for the amount and variety of its esculent products. —
Many of the fruits are valuable, and some of them eminently delieiotis ; while
the type of the Order (Rosa) is by universal consent regarded as the Queen of
Beauty, among./Zwers. A few of the drupaceous species contain a somewhat dan-
gerous quantity of Prussic Add, in the nuts and leaves ; but in the Peach, for in
stance, there is just enough of that formidable ingredient to give to the pulp an
exquisite flavor,* — and the fleshy or succulent fruits of the Order are, almost
without exception, innocent and wholesome.

SUBORDER I. AMYGDAVLEAE.

Trees, or sJirubs; leaves simple ; stipules free', ovary solitary, free from the decid-
uous calyx, with 2 suspended collateral ovuks, and a terminal style ; fruit a drupe,
mostly 1-seeded by abortion.

f Nut with the surface rugosdy furrowed.
HO. PER'SICA, Tournef.

[A name derived from Persia, — its native country.]

Calyx tubular, with 5 spreading segments. Drupe oval, tomentose
or smooth, the succulent pulp adherent, or separable from the nut.
Small trees : leaves oblong-lanceolate, serrate, conduplicate in the
bud ; flowers solitary or in pairs, subsessile, preceding the leaves.

1. P. VULG\RIS, Mill. Fruit densely tomentose.
COMMON PERSIC A. Peach. Peach-tree.

Stem 8 to 12 or 15 feet high, branching. Leaves 3 to 5 or 6 inches long; petioles
about half an inch in length, channelled above, and glandular near the leaf. —
Flowers pale-red or purplish. Drupe 1 to 2 inches, or more, in diameter, with the
pulp white, yellow, or reddish, adherent to the nut (clingstone), or separable from
it (freestone).

* Judging from observation, it would seem to be not generally known to our
Pastry Cooks, that a Peach Pie baked with the fruit whoU (i. e. simply pared, but
the nut left in the Peach) is vastly superior to one made of the mere fleshy portion,
cut in pieces. The process of baking— &s I suppose— elicits the prussic acid from
the seed of the peach, and diffuses it through the pulp, — imparting to it a sprightly
and delicious flavor, far beyond what it possesses when the stone is previously
rejected.

KOSACEAE 71

Hob. Yards, gardens, and orchards. Nat. of Persia. Fl. April. Fr. Aug.

Obs. The fruit of this tree — like the most of those which have
had the advantage of long and careful culture — presents numerous
varieties; the best of which may be pronounced (mejudice] superior
to all other known fruits. The tree, unfortunately, is short-lived ;
but it is readily propagated from seeds, — and a succession may be
kept up by inserting upon young stocks, buds, or scions, taken from
the most approved varieties* This process, for changing the char-
acter of seedling trees, is alluded to by the great English Bard with
his usual felicity: —

" You see, we marry

A gentler scion to the wildest stock;

And make conceive a bark of baser kind

By bud of nobler race : This is an art

Which does mend natilre, — change it rather: but

The art itself is nature." Winters Tale. Act 4.

a. P. LAEVia, DC. Fruit smooth.

SMOOTH PERSICA. Nectarine.

Hob. Yards, gardens, and under glass. Fl. April. Ff. Aug.

Obs. This small tree is scarcely to be distinguished from the pre-
ceding, except by its smooth fruit, — which presents the same varie-
ties, of clingstone and freestone. Prof. DE CANDOLLE admits it as a
distinct species ; but it is certainly very closely allied to the Peach, —
and, indeed, there are instances recorded, in which the same tree is
said to have produced both varieties. The crop of fruit is much
more certain under glass, with the branches trained on espaliers.

111. ARMEtfIAvCA, Tournef.
[A name derived from Armenia, — its native Country.]

Calyx campanulate, the 5 segments reflexed. Drupe roundish-oval,
velvety-pubescent; nut compressed, one edge obtuse, the other
acute. Small trees: leaves subcordate or ovate, convolute in the
bud ; flowers white, solitary, or few from a bud, preceding the
leaves.

1. A. VULGARIS, Lam. Leaves orbicular-ovate, shortly acuminate,
serrate-dentate ; flowers sessile.

and half in length, mostly with cup-like glands near the base of the leaf. Drupes
oval, about an inch in diameter, yellowish when mature.
Hob. Yards, and gardens. Nat. of Armenia. Fl. April. Fr. July.

Obs. The name of this fruit, in SHAKSPEARE'S time, was written
" Apricocks" (perhaps by a corruption of the latin, A. praecox —
meaning Early Armeniaca), — as We may perceive in the following
lines: —

" Go bind thou up yon' dangling Apricocks,
Which, like unruly children, make their sire
Stoop with oppression of their prodigal weight."

King Rithard IT.
This is an admired fruit ; and might be much more common than

it now is, if people were a little more attentive to such matters. —
Indeed, it is melancholy to reflect how thoughtless and negligent
mankind generally are, with respect to providing fruit for themselves.
There are few persons who do not own or occupy sufficient ground
to admit of 3 or 4 choice fruit-trees, and a grape vine ; — such, for
instance, as an Apricot, a Peach, a May-duke Cherry, a Catharine
Pear, and a Catawba Grape: yet the great majority seem never to
think of planting such trees, — while they are ready enough to in-
vade the premises, and revel on the fruits, of some more provident
neighbor ! It is due to the minor morals of the community, that
such disreputable negligence, and such marauding practices, should
cease to be tolerated,

2. A. DASYcXuFA, Pers. Leaves ovate or oval, acute, doubly ser-
rate ; flowers pedicellate.
HAIRY-FRUITED ARMENIACA. Black Apricot.

Leaves 2 to near 3 inches long; petioles about an inch in length. Drupes subglo-
bose, hairy, dark purplish color when mature.
Hob. Yards, and gardens. Nat. Country unknown. Fl. April. Fr. July.

Obs. This species has more of the habit of a Prunus, or Plum
tree, than the preceding, — and is reputed to be a more certain fruit-
bearer; though I have not found it so.

112. PRUNUS, Tournef.
[The classical Latin name for the Plum.]

Calyx campanulate, 5-cleft. Petals 5, spreading. Stamens 15 to
30. Drupe ovoid, oblong, or globose, glabrous, mostly covered
with a glaucous bloom ; nut compressed, both edges acute. Small
trees : leaves convolute in the bud ; flowers mostly preceding the

colors, from bluish-black to copper-color and pale yellowish-green, covered with
bloom, the flesh rather firm.

of insects render the fruit, generally, an uncertain crop, in country
places.

oblong or oblanceolate, acute, finely serrulate with glandular-pointed
teeth; umbels sessile, 2- to 3-flowered.
CHICASA PRUNUS. Chickasaw Plum. Mountain Cherry.

Stem 6 to 10 or 12 feet high, much branched, — the young branches slender, vir-
gate, dark purple, smooth and shining, the old ones geniculate and somewhat
thorny. Leaves 1 to 2 inches long, smooth ; petioles slender, ^ to % of an inch iu
length. Flowers appearing with the leave?, in sessile fascicles of threes. Drupes
globose, red or yellowish-red, nearly or quite destitute of bloom, with a tender pulp
and a thin skin.
Hub. Yards, and gardens. Fl. April. Fr. July.

Obs. This little tree (which is believed to be a native of our
South- Western territory, — where it is a small shrub, in its wild
state,) by long culture produces a very pleasant fruit, — worthy of
more attention than it has yet received. It approaches the Cherry
in character and appearance, and may be considered as a connecting
link between the Plum and Cherry; but it is unquestionably, I
think, a true Plum. Why MICHAUX'S specific name was permitted
to supersede MARSHALL'S (viz. angustifolia), which was published
long before, I do not understand.

113. CER'ASIJS, Tournef.

[The name of an Asiatic town, — whence the tree was obtained.]
Flower nearly as in Prunus : drupe globular or roundish-ovoid, often
umbilicate at base, glabrous, destitute of bloom; nut globose. —
Trees, or shrubs: leaves conduplicate in the bud; pedicels of the
flowers either in umbellate fascicles from lateral leafless buds, and
then rather preceding the leaves,- — or in racemes terminating leafy
branches, and coming after the leaves ; petals white.

f Flowers in naked lateral fascicles, preceding the leaves.

1. C. puiiiila, MX. Depressed or trailing, with ascending

74 DIALYPETALOUS EXOGENS

Stem, 30 to 60 feet or more in height, branching regularly, and somewhat rerti-

about as long as the petioles, slender, usually 3 (often 2) in a fascicle. Drupes of
various size and color, tender, and often very succulent, sweet, or bitterish-sweet,
Hob. About houses; along fence-rows, &c. Fl. April. Fr. June.

Obs. Cherries are said to have been originally brought to Rome
from Cerasus, a city of Pontus, by the Roman Consul and General,
LUCULLTJS, some 60 or 70 years before the Christian era (ab urbe
conditd' 680. Willd.}; and from Rome they have been distributed
over the rest of the civilized world. Our cultivated Cherry trees
seem obviously to consist of at least two original species, — viz. the
sweet "English Cherry" so called — and the common Sour Cherry.
The numerous varieties — produced by long culture (and possibly
some hybrids, such as the "May-duke" &c.) — may perhaps be all
referred to one or the other of those two ; though Prof. DE CAN-
DOLLE distributes them iniofour species. There are, undoubtedly,
several very distinct sorts of fruit, — and I have not seen all the
trees which produce them : but I incline to think that the general
habit and aspect of the trees -commonly seen in this country, warrant
the reduction of them all to the two above referred to.

3. C. VuLGXms, Mill. Branches spreading, slender and flexible;
leaves lance-ovate and obovate, acute or acuminate, mostly narrowed
at base, serrate, smoothish ; drupes globose.

COMMON CERASUS. Red or Sour Cherry. Morello Cherry, &c.

Stem 10 to 20 feet high, irregularly branched ; branches rather slender and
flaccid, spreading nearly horizontally and forming a roundish bushy top. Leaves
1% to 3 inches long; petioles half an inch to an inch in length. Pedicels of the
flowers about as long as the petioles, 2, or more frequently 3, in a fascicle. Drupes
fleshy, more or less acid, red or dark purple when mature.
Sab. Fence-rows; along lanes, &c. FL April. Fr. July.

Obs. The "Sour Cherry'* is the most common and, for culinary
purposes, the most valuable of the genus. The Morello Cherry is a
remarkably fine variety, with a rich purple juice,— and in the days
of " Cherry Bounce," was a great favorite: But, for the last 30
years, it has almost entirely failed, in this region, — in consequence,
apparently, of the ravages of an insect, causing large warty excres-
cences on the branches of the tree.

to 4 or 5 inches long, suhcoriaceous ; petioles half an inch to three-quarters in
length. Racemes 2 to 4 or 5 inches long, terminating the short branches which
arise from the last year's growth. Drupes globose, small, dark-purple or purplish-
black when mature, succulent, bitter and mawkish to the taste.
Hob. Along streams, fence-rows, Ac.: frequent. Fl. May. Fr. Aug.

Obs. The wood of this species is a pale reddish-brown, close-
grained and hard — taking a good polish ; and was formerly much
used by cabinet-makers. The bark — though a rather unpalatable
bitter— 4s a good tonic. The leaves are a favorite food of caterpil-
lars ; and the ripe fruit is greedily devoured by birds.

SUBORDER II. ROSAVCEAE PROPER.

purplish. Leaflets 2 to 4 inches long, subsessile. Flowers white, or slightly
tinged with red, loosely corymbose-paniculate.
Hob. Woodlands, and thickets : frequent. Fl. June. Fr. Aug.

Obs. This plant has had considerable reputation for its medicinal
properties ; but is rarely resorted to, at present. There is another
species, with large stipules, in the West. The Kerria Japonica,
DC. (Corchorus Japonicus, Thunberg], or golden Globe-flower, — a
suffruticose plant of this Tribe, — has been extensively introduced
among ornamental shrubbery, and is becoming almost naturalized.

Stem 2 to 3 feet high, paniculately branched at summit, more or less hairy. —
Leaflets 2 or 3 inches long, ovate or rhomboid ; common petioles 4 to 6 or 8 inches
in length. Lower stem-leaves mostly trifoliolate : upper lednes simple, lanceolate,
incised-serrate. Carpel-s bristly ; styles finally divaricate, or reflexed ; stigmas ar-
ticulated to the styles, — when the flower expands, the stigmas and styles become

[Latin, diminutive of potens, powerful ; alluding to reputed virtues.]
Calyx 5-cleft, with a bract at each sinus, and thus appearing 10-
cleft. Petals 4 or 5. Stamens numerous. Akenes many, in a head
on the dry hairy receptacle. Mostly herbs: leaves compound;

terminal.

Obs. This coarse and rather homely weed is considered as indige-
nous, in the northern States ; but it has the appearance, to me, of
an introduced plant, here.

2. I". Canaclciisis, L. Villous; stem procumbent or ascending,

producing runners ; leaves quinate-digitate ; leaflets cuneate-obovate,

incised-dentate.

Also, P. simplex. MX. $ Fl. Cestr. ed. 2. p. 304.

CANADIAN POTENTILLA. Cinque-foil. Five-finger.

Perennial. Stem 2 or 3 to 12 and 18 inches long, slender, somewhat branched,
often several from the same root. Radical leaves on petioles 2 to 6 or 8 inches in
length ; stem-leaves nearly sessile ; leaflets half an inch to 1 or 2 inches long. P«-
duncles axillary, 1-flowered, about as long as the leaves.
Hob. Old fields; borders of woods, &c.: frequent. Fl. April. Fr. June.

Obs. The P. simplex, of Authors, with slender ascending stems,
and taller growth — frequent along the borders of open woodlands,
and in clearings — is doubtless very properly reduced to a variety of
this. The prevalence of the plant, in arable lands, is a pretty sure
indication of a thin soil, or of a thriftless farmer, — or both ; though
some lands, when kept as pasture fields, seem to have an almost
incurable tendency to lose the valuable grasses, and to become
speedily overrun with Cinque-foil. Lime and manure, however —
if duly persevered with — will work wonders in the poorest soils.

120. FRAGAVRIA, Tournef.
[Latin, fragrans, odorous; in reference to its fragrant fruit.]
Flowers nearly as in Potentilla: styles lateral. Akenes minute,
scattered superficially on, or imbedded in, the surface of the en-
larged ovoid pulpy deciduous receptacle. Perennial hairy herbs :
nearly or quite stemless, — but producing prostrate runners: leaves
trifoliolate ; flowers white, cymose on scapes, — often dioicous, or
imperfect, under cultivation.

1. F. > irgilliilua, Ehrh. Akenes imbedded in the deeply pitted
receptacle.

VIRGINIAN FRAGARIA. Wild Strawberry.

Root (or rhizoma) thickish, with numerous fibres. Runners creeping, or strik-
ing root at intervals. Leaves mostly radical ; common petioles 2 to 4 or 6 inches in
length; leaflets 1 to 2 inches long, cuneate-obovate, or oval. Cymes on scapes
scarcely as tall as the leaves. Receptacle (vulgarly regarded as the fruit) ovoid,
nodding, succulent and bright purple when mature.
Hob. Neglected old fields; fence-rows, &c.: frequent. Fl. April. Fr. May.

2. F. VE"SCA, L. Akenes superficially attached to the receptacle.
EATABLE FRAGARIA. Garden Strawberry.

Hob. Gardens, &c. Nat. of Europe. Fl. April. Fr. May.

Obs. Long and careful culture of this species (which is very
nearly allied to the preceding, and said to be truly indigenous) has
resulted in numerous fine varieties, differing in the size, color, and
flavor of the receptacles ; and has also produced many abortive or

i

BOSACEAE 79

imperfect flowers, — which have given rise to much idle controversy
about their sexual character, among the practical gardeners. —
Although the true fruit of this plant consists of mere dry specks, or
bony particles (i. e. the minute akenes), scattered over the surface
of the enlarged receptacle, — yet the receptacle itself furnishes a
pulpy substitute of the most delicious character.

121. RITBUS, L.

[Celtic, Rub, red; from the color of the fruit, of some species.]
Calyx 5-parted, without bractlets at the clefts. Petals 5. Stamens
numerous. Pistils crowded on a convex, or oblong, spongy recep-
tacle, becoming small drupes. Perennial suffruticose plants: leaves
mostly compound; flowers generally white, andthe/rw'2 edible.

ODOROUS RUBUS. Rose-flowering Raspberry.

Stem 3 to 5 feet high, branching. Leaves 4 to 6 or 8 inches long, and nearly as
wide as long ; petioles 2 to 4 or 6 inches long. Corymbs compound, clothed with a
purplish clammy glandular pubescence ; flowers large, bright^purple, or sometimes
pale-red. Fruit broad, on a large receptacle, bright-red, or scarlet, when mature.
Hob. Rocky hills ; Brandywine : rare. Fl. June. Fr. Aug.

Obs. This is a showy species, with flowers nearly as large as those
of the Rosa rubiginosa, or sweet-brier. It is sometimes introduced
into gardens, — where it is rather troublesome in sending up suck-
ers from its creeping roots. It very rarely produces fruit, under
cultivation ; but I have seen it, on the mountains, bearing flowers
and ripe fruit, at the same time,

f t Leaves pinnately 3-5-foliolate.

2. R. STRIGOVSUS, MX. Stems slightly glaucous, beset with stiff
bristles, some of them becoming weak hooked prickles; leaflets
oblong-ovate ; fruit light red.

STRIGOSE RUBUS. Red Raspberry.

Stem 3 to 4 or 5 fact high, light brown. Lower leaves odd-pinnate by fives, the
upper ones ternate ; leaflets about 3 inches long, hoary beneath, the terminal one
often cordate at base. Corymbs 4- to C-flowered, axillary and terminal, often ag-
gregated and forming a leafy panicle at summit.
Hob. Gardens, yards, &o. FL May. Fr. July.

Obs. This species is indigenous on our mountains. I have seen
it, abundant, on Pokono ; and in our gardens, here, I think it is
often mistaken for a variety of the following, — to which, indeed, it
is nearly allied.

3. R. IDAEUS, L. Stems not glaucous, hispid below, prickly above ;
leaflets rhombic-ovate ; fruit amber-colored, pale yellow, or purple.
IDA RUBUS. Antwerp Raspberry. Garden Raspberry.

Stem 3 to 5 feet high, branching, — the hispid bark, below, exfoliating the second
year. Lower leaves odd-pinnate by fives, the upper ones by threes ; common petiolet

fine short velvety pubescence.

Hob. Gardens, &c. Nat. of Europe. Fl. May. Fr. July.

Obs. The fruit of this is much admired; and the plant, in conse-
quence, extensively cultivated. Many superior varieties (and per-
haps hybrids) have been produced by scientific cultivators, — among
whom Doctor BRINCKLE", of Philadelphia, is one of the most distin-
guished and successful.

4. R. OCCidentalis, L. Stem smooth and glaucous, armed
•with prickles; leaflets lance-ovate; fruit dark purple or nearly
black.

WESTERN RUBUS. Wild, or Black Raspberry. Thimble-berry.

Stem 5 to 8 or 10 feet long, sparingly branched, limber and often arching over so
that the summit comes to the ground and takes root, mostly purplish, and
pruinose or covered with a fine bluish-white powder. Leaflets mostly in threes, 2
to 4 inches long, often subcordate at base, smoothish above, clothed with a dense
glaucous tomentum beneath. Corymbs mostly terminal on the young branches.

Obs. Every one knows the common Brier. The root, both of this

and the R. Canadensis, being moderately astringent, is a popular

remedy for diarrhoea. The nipe fruit affords a pleasant jam, — which

is also considered salutary, in bowel complaints. Even the knots

Obs. This species is the one which has been chiefly cultivated for
hedging, in this County, — where it was introduced, from the vicinity
of Washington City, about the commencement of the present cen-
tury. It makes a handsome hedge, when well managed ; but not
so substantial and effective as the Cockspur Thorn. It is so subject
to be injured, and broken into gaps, by thoughtless and reckless
trespassers — especially near villages — that the attempt to cultivate
it is rather a source of vexation, than of satisfaction.

06*. There appears to be two pretty distinct varieties of this;
both of which, however, are so rare, that I am not quite sure they
are truly indigenous here. The Cock-spur Thorn, in my judgment,
is decidedly the best for making a durable and effective hedge : But,
until timber shall become scarce, very few farmers will take the
requisite pains to insure a complete hedge, — and without such
care, it is worse than labor lost to make the attempt. In the lan-
guage of Mr. M'MAHON'S excellent " American Gardener's Calendar"
referring to the hedging experiments of negligent, slovenly farmers :
" I would advise such to hold fast by the post and rail, and not to
lose time in doing more harm than good."

Fruit 1 to 3 or 4 inches in diameter, fleshy, of various colors.
Hob. Orchards, yards, Ac. Nat. of Europe. Fl. May. Fr. Aug. and after.

Obs. The varieties of this — like the Pear — have been rendered
almost numberless, by long and careful culture. It is much to be
regretted, however, that so little attention has been hitherto paid,
in this County, in selecting the best. A new era, it is hoped, is
now dawning upon those who have orchards to plant. %£~^

Preserves, or sweet-meats. The Quince is supposed to be the golden
apple of the Hesperides, so celebrated in ancient fable ; but if the
Orange had been then known, it would doubtless have been esteemed
a more precious fruit, by "the Western Maidens." The C. Japon-
ica, Per 8. or Flowering Quince (Pyrus Japonica, Willd.}, is highly
prized for its beauty as an early-flowering shrub; butthe/rwi —
though remarkably fragrant — is very hard and acerb.

Obs. Collected in 1837, by Mr. ALBERT TOWNSEND. The specific
name, given by LINNAEUS, is rather unfortunate, and calculated to
mislead the young Botanist, — as the leaves are much broader, and
every way larger, than in some of the forms of E. palustre. The
plant, in fact, is quite pretty,— with a large raceme of showy flow-

Hob. Moist, shaded places: frequent. Fl. July. Fr. Aug.

Obs. Dr. DARWIN, in his Botanic Garden, devotes a number of
lines to the vulgar notions formerly connected with this plant. The
following are the initiatory couplets: —

" Thrice round the grave CIRCSEA prints her tread,
.And chaunts the numbers which disturb the dead ;
Shakes o'er the holy earth her sable plume,
. Waves her dread wand, and strikes the echoing tomb ! "

He informs us, in a note, that it "was much celebrated in the
mysteries of witchcraft," &c. and remarks, that "the superstitious
ceremonies or histories belonging to some vegetables have been
truly ridiculous : " — such as those of the Druids with the Mistletoe, —
the legend of the Mandrake, — the wearing of Paeony roots, as amu-
lets,— and the use of the Hazel twig, or Divining Kod, in discovering
ores, and fountains. He adds, that, in the very year when he was
writing, "there were many in France, and some in England, who
underwent an enchantment without any divining rod at all, and be-
lieved themselves to be affected by an invisible agent, which the
Enchanter called Animal Magnetism!"

1. L. vuLGXms, Ser. Softly viscid-pubescent; leaves roundish-
cordate, acuminate ; fruit clavate-ventricose.
COMMON LAGENARIA. Calabash. Bottle Gourd.

Plant emitting a fetid musky odor; stem 10 to 15 or 20 feet long, slender, branch-
ing, climbing by 2- to 4-cleft tendrils. Leaves 4 to 6 or 8 inches long ; petioles 2 to 6
inches long. Flowers white, with green nerves and veins, axillary, on long pe-
duncles. Fruit 12 to 18 inches long, unequally biventricose, finally nearly hol-
low, or partially filled with the loose dry suberose placentae,— the rind, or shell,
becoming smooth, thin and hard. Seeds with a dry membranous arillus.

^ Obs. The firm woody shell, of the fruit, affords a convenient
kitchen utensil, — for which the plant is cultivated, by cottagers and
farmers who cannot afford, or do not choose, to purchase more
costly ones. WILLDENOW seems to have had a high opinion of its
value, in domestic economy. Under the head of Usus, he mentions
"Lagenae, Cochlearia, Infundibula, Pilei, innumeraque Utensilia." It
might serve all these purposes, in a primitive state of society ; but
our people have generally got rather past that. There is occasion-
ally cultivated, for the table, a cucurbitaceous fruit of extraordinary
length, called " vegetable marrow," — which seems to belong to this
species, and may, perhaps, be the variety clavata, of SERINGE and DE
CANDOLLE.

with a tender sweet watery frosty-looking or crystalized pulp within, which is
usually purplish or reddish-orange color. Seeds black, or purplish brown.
Hab. Gardens, Ac. Nat. of India and Africa. Fl. June. Fr. Aug.

Obs. There is a nearly allied plant, often seen in gardens, which
bears a different /rmZ — known by the name of " Citron," — the firm
rind of which is used in making sweetmeats, or "Preserves." The
interior is also firm, and does not become red, tender and watery,
like the common Water Melon : yet the whole aspect of the plant,

Obs. This Cucumber-like Vine has found its way into some gar-
dens ; where it is something of a nuisance, and rather difficult to
get rid of. The Balsam Apple (Momordica Balsdmina, L.J, which
belongs to this section, is sometimes seen in gardens ; but is scarcely
entitled to a place in our Flora — even among cultivated plants.

Hob. Fields, and gardens. Nat. of the East. Fl. July. Fr. Octo.

Obs. The fruit of this is valuable for stock, — ahd some of the
varieties excellent for the table. It is liable to be injuriously hy •
bridized, when growing in the immediate vicinity of Squa'shes. I
have had a crop of Pumpkins totally spoiled, by thoughtlessly
planting Squashes among them; the fruit becoming hard, warty
and woody, — unfit for the table, and unsafe to give to cattle.

sometimes warty.
Hob. Gardens, &c. Nat. country uncertain. Fl. July. Fr. Octo.

ORDER XLIY. UMBELLIF'ERAE.

Herbs; flowers in (usually involucrate) umbels; calyx-tube entirely adherent to the
ovary ; petals 5 ; stamens 5, inserted (alternately) with the petals, on the disk that
crowns the ovary and surrounds the base of the 2 styles; fruit consisting of 2
seed-like dry carpels;* seeds solitary, suspended; embryo minute, in the apex of
copious horny albumen. Stems usually hollow ; leaves alternate, generally much
dissected, exstipulate, but the petioles more or less dilated and sheathing at base.

The plants of this Order are much less numerous in our country, than in the
old world. Of the 28 species here described, 9 have been introduced, — and of these,
6 or 7 are cultivated.

* The carpels of the umbelliferae are usually marked with a definite number of
longitudinal ribs, which are sometimes dilated into wings; the intervals, or chan-
nels, between the ribs — as also the commissure (or face, by which the carpels are
joined) — often contain one or more linear receptacles of aromatic oil, — which re-
ceptacles are called vittae, or fillets. Those ribs on the carpels, are distinguished
into primary, and secondary. The primary ones (10 in number on the 2 carpels —
or 5 on each,) are pretty constant, and more or less conspicuous, — representing
the midribs and sutures of the 5 sepals, which, by their union, form the tube of the
calyx and coating of the fruit. The 5 ribs which answer to the midribs of the
sepals, are termed carinal ribs, and their extension at apex forms the 5 calyx-
teeth. Alternating with these primary ribs, there is sometimes a development of
secondary ones, — which Prof. DE CANDOLLE regards as representing lateral nerves
(i. e. one on each side of the midrib) of the sepals. The ribs and vittae — together
with the form, or manner of compression, of the fruit — afford important aid in de-
termining the generic character of the plants of this remarkably natural family :
and consequently, the student, or young herborizer, should always bear in minti
that it is requisite to have specimens of umbettiferae with full-grown fruit.

into the fields, and along fences, — where it speedily degenerates,
and, if neglected, becomes a troublesome unsightly weed.

UMBELLIFERAB 103

Obs. The plant which I have taken for this, is becoming so rare,
and my specimens are so defective, that I may be mistaken in it. —
The T. atropurpureum, Nutt. may probably yet be found along the
Schuylkill, within this County ; but it has not, thus far, been de-
tected.

f 1 1 Carpels laterally compressed, or contracted ; ribs not winged.

157. ZIZ'IA, Koth.

[Dedicated to J. B. Zizii; a German Botanist, collaborator of Koch.]
Fruit oval; carpels contracted at the junction so as to appear didy-
mous ; ribs 5, nearly equal ; channels with 1 to 3 vittae. Mostly
smooth, yellowish-green perennials, — with yellow flowers, and a gen-
eral resemblance to Thaspium.

1. Z. C'Orcliitcl, Koch. Radical leaves undivided, cordate, cre-
nate-dentate ; stem-leaves ternately dissected; segments ovate, ser-
rate ; ribs of the carpels conspicuous ; vittae single.

sometimes from the base, purplish when young. Leaflets 1 to near 2 inches long ;
common petioles dilated, ribbed, and purplish. Umbels mostly terminal, on pedun-
cles 3 to 6 inches long; rays very slender, 1 to 3 inches long, spreading, some of
them often divaricate.
Hab. Rocky hills : not common. Fl. May. Fr. July*

158. BUPLJEtPRUM, Tournefi

[Gr. Bous, an Ox, and Pleuron, a rib, or side ; but the application is obscure.]

Fruit ovate-oblong; carpels somewhat didymous in appearance, 5-
ribbed; channels with or without vittae. Annuals, or perennials:
leaves simple, mostly entire; flowers greenish-yellow; involucre

lary; ribs of the carpels rather broad,— the channels reddish brown, filled with
•aromatic oily matter.
Hob. Margins of swampy rivulets : frequent. Fl. July. Fr. Sept.

Obs. The mature fruit of this plant has a strong anisate odor. —
The root is poisonous ; and the lives of children, and others, are
often endangered and sometimes destroyed by eating it, in mistake
for that of the Sweet Cicely (Osmorrhiza longistylis, DC.}. The her-
bage is also said to be destructive to cattle, when eaten by them: —
all which serves to show the importance of sufficient Botanical
knowledge, among the people, to enable them to understand, and
avoid or extirpate the evil.

160. SMJM, L.

[Supposed to be from the Celtic, Siu, water,— its usual habitat.]
Fruit orbicular-ovate, flattish at the sides; carpels with 5 equal
prominent obtuse ribs ; vittae numerous. Aquatic or marsh peren-
nials : leaves odd-pinnately dissected ; involucre and involucels many-
leaved ; flowers white.

oblong-lanceolate, incised-serrate, sometimes pinnatifid, unequal at
base, sessile, the terminal one petiolulate, often 3-lobed.
BROAD-LEAVED SIUM. Water Parsnep.

Stem 2 to 4 or 5 feet high., stout, angular, with broad furrows, smooth, yellowish-
green, much branched. Leaflets 2 to 4 inches long, varying from linear-lanceolate
to ovate-lanceolate, tapering to an acute point. Umbels spreading, of numerous
unequal rays ; fruit crowned with a conspicuous yellowish disk.
Hab. Swamps, and margins of streams : frequent. Fl. July. Fr. Sept.

Obs. A nearly allied plant, with very narrow, sublinear leaflets,
has been found along the Schuylkill, on the northern side of the
County, which, probably, is the 8. linedre, of MX. but I have not
had an opportunity to examine it, satisfactorily.

161. CRYPTOTAEV]VIA, DC.

[Gr. Kryptos, hidden, and Tainia, a fillet; the vittae being concealed.]
Fruit linear-elliptic; styles subulate, persistent; carpels with 5
equal obtuse ribs ; vittae slender, 1 in each channel, and 1 concealed

volucels few-leaved ; flowers white.

1. C. CanadensiS, DC. Leaflets rhombic-ovate to lanceolate,
doubly and sharply incised-serrate, subsessile.

UMBELLIFERAE 105

CANADIAN CRYPTOTAENIA. Hone- wort.

Stem about 2 feet high, rather slender, branched above. Leaflets 2 to 4 inches
long, serrate to the very petiole. Umbds terminal and subterminal, somewhat in
pairs. Carpels with linear flattish ribs; channel* dark brown; vittae visible only
in a transverse section of the carpels.
Hab. Woods, and shaded places : frequent. Fl. June. Fr. Aug.

Obs. This is a Comparatively harmless native weed, — frequent in
shaded places about dwellings: But, there is a foreigner, with some-
thing of its general habit and aspect (viz. Aegopbdium Podagrtiria,
L.), which has been introduced into some lots and gardens, in Ger-
mantown, near Philadelphia, — and proves to be a nuisance, not easily
abated. It has hitherto resisted all attempts to get rid of it ; and
Sir J. E. SMITH, in his Flora Britannica, says of it — "radix rcpcns.
vix exstirpanda." In DON'S General System of Gardening and Botany,
it is also remarked pf the Aegopodium, that "being a great creeper,
it cannot be admitted into gardens, for after it gets hold it is next
to impossible to eradicate it again." P. COLLINSON, writing to
JOHN BARTRAM, says, "it is a notorious running weed in the gar-
den." A plant of such character (and worthless beside,) deserves
to be studied, and watched that it may be avoided.

162. A'PIIJM, L.

[From the Celtic, Apon, water; near which it naturally grows.]
Fruit orbicular ; stylopodium (base of the styles) depressed ; carpels
with 6 filiform equal ribs ; carpophore (central axis of the fruit) un-

Umbels terminal and axillary, — the axillary ones subsessile.
Hab. Gardens, Ac. Nat. of Europe. Fl. July. Fr. Sept.

Obs. The petioles, when blanched, become succulent and tender ;
and are a favorite salad. The var. RAPACEUM, DC. or Turnep-rooted
Celery, is also cultivated by amateurs.

163. PETROSEMWITM, Hoffm.

[Gr. Petra, rock, and Selinum, — Rock Selinum; from its native habitat.]

glaucous. Segments of the leaves an inch to an inch and half long, almost filiform,
the subdivisions often dichotomous; common petioles much dilated, sheathing,
produced into 2 marginal lobes at summit. Umbels of numerous unequal rays.
Hab. Gardens, &c. Native of Europe. Fl. July. Fr. Sept.

Obs. The whole plant is highly aromatic. Those who kept Sees,
in former years, were much in the practice, when those insects
twarmed — (after ringing the frying-pan, to make them settle !) — of
rubbing the inside of the Hive with this fragrant herb, under the
impression that the odor would attach them to their new domicil. —
The F. dulce, or Sweet Fennel — with the stem subcompressed at
base, and the umbels fewer-rayed — is sometimes, though rarely, to
be seen in our gardens.

peduncles 2 or 3 to 6 inches long; fruit about half an inch long, tapering to a
bristly stipe, at base.
Hab. P.ich, moist, rocky woods : frequent. Fl. May. Fr. Aug.

leaflets pinnatifidly incised; styles conical, not half as long as the
ovary.

SHORT-STYLED OSMORRHFZA.

Hoot of a sweetish, mawkish taste, — something like that of Aralia nudicaulis, L.
Stem about 2 feet high, mostly fistular, branching. Leaves and umbels nearly as
in the preceding.

gibbous, crowned with the dilated base of the diverging styles; carpels with the
faces inclining to separate between the base and apex ; channels brown.
Hob. Waste places. Nat. of Europe. Fl. June. Fr. Sept.

Obs. This foreigner is naturalized about some old settlements ;
and being a powerful narcotic poison, it ought to be known wherever
it exists. It is supposed, indeed, to be the very herb with which
the ancient Greeks put their philosophers and statesmen to death,
when they got tired of them. The root is said not to be poisonous.

SUBORDER III. CCELOSPER'MAE.

Inner face of the carpels hollowed transversely, or the base and apex curved in-
ward.

169. CORlAtf'ORUM, Hoffm.

[Gr. Koris, a bug ; the bruised leaves having the odor of a bed-bug.]
Fruit globose; stylopodium conical; carpels closely cohering; ribs
broad, obsolete; channels without vittae. Mostly annual : smooth ;
leaves bipinnately dissected ; involucre 1-leaved or none; involucels
halved, about 3-leaved; umbels few-rayed; flowers white, or tinged
with red before expanding.

1. C. SATIVVUM, L. Segments of the lower leaves broadly cuneate,
of the upper ones narrow and linear ; carpels hemispherical.
CULTIVATED CORIANDRUM. Coriander.

Stem 1 to 2 feet high, slender, somewhat branched at summit. Umbels spread-
ing, 3- to 5-rayed ; umbeUets of numerous short unequal rays ; carpels very concave
on the face, cohering by their margins so as to form apparently a simple globose
fruit ; commissure with 2 vittae in a loose membrane.
nab. Gardens. Nat. of Tartary. Fl. June. Fr. Aug.

Obs. Occasionally cultivated for its aromatic fruit. Notwith-
standing the offensive odor of the fresh herb, Prof. DE CANDOLLE
states that the Tartars prepare a favorite potage from it. His words
are — "Herba recens in deliciis habetur et ex ea* jusculum conficitur,
unde ubique in hortis Tataricis culta." Prodr. 4. p. 250. It would
probably require a Tartar palate to relish soup, prepared with her-
bage which has the "odor of a bed-bug!"

ORDER XLV. ARALIACEAE.

Herbs, or shrubs; leaves alternate, mostly compound, without stipules ; flowers in
simple umbels, or compound umbellulate racemes ; calyx-tube adherent to the
ovary; petals mostly 5, valvate in the bud; stamens as many as the petals, and
alternate with them ; ovary of 2, 3, 5, or more, connate carpels (with as many
etyles), becoming baccate or drupaceous in fruit, — sometimes nearly dry ; seeds
solitary, appended to the apex of each cell (or carpel) ; embryo in the apex of fleshy

involucels small.

RACEMOSE ARALIA. Spikenard.

Root thick, aromatic. Stem 3 to 5 feet high, rather stout, with spreading and
somewhat dichotomous branches. Leaflets 3 to 6 or 8 inches long, slightly hairy,
mostly petiolulate. Berries small, not torulose, dark purple when mature.
Hob. Rich woods; Brandy wine hills: not common. Fl. July. Fr. Sept.

Obs. This is often introduced into gardens. The root and berries,
infused in alcohol, made a favorite Tincture, in times past, for
those who indulged in the perilous habit of taking such stomachics.
JOHN BARTRAM, in his appendix to SHORT'S Medicina Britannica,
printed at Philadelphia, 1751, says the plant was called " Wild
Liquorice. "

2. A. liudicaiilis, L. Stem very short; leaf mostly solitary,
subradical, triquinate; leaflets ovate or oblong-oval, serrate; um-
bels simple, 3 on a naked scape ; involucre none.

NAKED-STEM ARALIA. Sarsaparilla.

Root creeping, thickish and long, somewhat aromatic, but mawkish. Stem
scarcely more than the crown of the root. Leaf on an erect petiole 6 to 12 inches
long, 3-parted at summit, — each division 2 to 4 or 5 inches in length, and bearing
5 odd-pinnate subsessile leaflets. Scape 4 to 6 or 8 inches high, divided at summit
into 3 smoothjsh peduncles about 2 inches long, each bearing a naked many-flowered
globose umbel an inch or inch and half in diameter. Berries larger than the pre-
ceding, torulose, purplish-black when mature.
Hob. Rich, rocky woodlands : frequent. Fl. May. Fr. July.

Obs. The root of this is sometimes used as a substitute for the
Sarsaparilla, of the shops (a species of Smilax). I believe both the
original, and the substitute, to be rather innocent medicines, — -provi-
ded the disease be not serious !

f f Stems suffruticose, or woody.

3. A. hispida, MX. Stem suffruticose and bristly at base ; leaves
bipinnate ; leaflets lance-ovate, incised-serrate ; umbels axillary
and terminal, on long peduncles.

hispid. Umbels corymbose, on branching peduncles 2 or 3 to 6 inches in length ;
invol-ucre of numerous subulate leaflets.
Hob. Hills, along Schuylkill : rare. Fl. June. Fr.

Obs. The mature fruit, of this species, I have not seen. The A.
spinbsa, L. or Angelica Tree — a stout prickly shrub, with thick
club-like branches, and large bipinnately compound leaves — is oc-
casionally to be seen about old settlements, where it has been intro-
duced.

the central flowers often abortive, fruit drupaceous, shining crimson when ma-
ture.
Ilab. Rich woods; Brandy wine: rare. Fl. July. Fr. Sept.

Obs. This plant is interesting, as having afforded an article of
some commercial importance, in our trade with China, — rather
than from any inherent virtues.

—the leaves in opposite pairs, sessile, white and petal-like, sometimes tinged with
purple. Flowers greenish-yellow.
Hob. Woodlands : very common. Fl. May. Fr. Septem.

Obs. The wood of this small tree is very close-grained and firm,
and valuable for many purposes in mechanics. Cabinet-makers
sometimes employ it, in the manufacture of small articles of furni-
ture,— in which, my friend Dr. ELWYN assures me, it is very beauti-
ful. The woodman selects it as the best material for wooden wedges.
The young straight stems make good hoops, for the cooper; and the
slender verticillate branches once furnished distaffs for Spinsters, — in
the "good old times," when that description of females had a prac-
tical existence in the community. The bark is an excellent tonic, —
almost rivaling the Cinchona, in efficacy. A century since, accord-
ing to KALM, there was so much faith in the virtues of the Dogwood,
that "when the cattle fall down in spring, for want of strength, the
people tie a branch of this tree on their neck, thinking it will help
them !" Altogether — and without any joke — it is a valuable as well
as ornamental little tree, — worthy of a place in lawns and yards. —
Observing farmers have remarked, that the proper time to plant
Indian Corn (Zea Mays, L.) is when the involucres of the Dogwood
are first developed.

112 GAMOPETALOUS EXOGENS

DIVISION II. GAMOPET'ALOUS EXOGENOUS PLANTS.

FLORAL ENVELOPES usually consisting of both calyx and corolla, —
the petals more or less united.*

ORDER XLVII. CAPRIFOLIAVCEAE.

Shrubs, or rarely herbaceous; leaves mostly opposite, and without stipules; calyx-
tube adherent to the ovary ; stamens usually as many as the lobes of the corolla,
and inserted on its tube ; ovary 2- to 5- celled ; fruit berrylike, or capsular ; embryo
in the axis of fleshy albumen.

TRIBE 1. LONICE^REAE.

Corolla, tubular, often irregularly lobed ; style long, filiform ; stigma capitate.

L.

[Dedicated to the memory of Adam Lonicer, an old German Botanist.]
Calyx-teeth very short. Corolla often irregularly 5-lobed, and some-
times gibbous at base. Ovary 2- or 3-celled. Berry several-seeded.
Twining or upright shrubs : leaves often connate ; flowers axillary.

J§SP" TWINING SHRUBS : leaves entire, upper ones connate ; flowers in axillary v erti-
cils, more or less fragrant; calyx-teeth persistent ; corolla ringent.

1. 1,. gr&tcl9 Ait. Leaves sub-perennial, obovate, 2 or 3 upper
pairs connate, the lower ones subpetiolate ; corolla not 'gibbous at
base, tube long.
AGREEABLE LONICERA. American Woodbine. Wild Honeysuckle.

Stem 10 to 15 or 20 feet long, branching, the young branches often pilose. Leaves
1 to 2 or 3 inches long, rather obtuse and often slightly emarginate, glaucous and
reticulately veined beneath. Flowers in verticils of about 6, in the axils of the
upper connate leaves ; corolla externally red or purplish, the limb at first nearly
white, soon becoming tawny yellow, — the tube an inch or more in length, tapering
to the base, and somewhat resembling a Cornucopia, smooth within. Stamens ex-
serted, about equalling the style. Berries orange red, at maturity.
Hah. Moist, rocky woods ; along streams : not common. Fl. May. Fr. July.

Obs. This species bears considerable resemblance to the common
cultivated species (L. Caprifblium, L.), — though the flowers have a
rather stronger and less agreeable odor. Honeysuckles have always
been favorite plants, for decorating arbors, and porticos; and are
much frequented by the exquisitely beautiful little Humming-bird.
They are thus alluded to, by SHAKSPEARE : —

" And bid her steal into the pleached bower,

Where Honeysuckles, lipen'd by the sun,

Forbid the sun to enter ; — like favorites,

Made proud by Princes, that advance their pride

Against that power that bred it."

* Some instances of dialypetalous flowers occur in this Division, in ORDER LIV.
ERICACEAE (viz : in the genus Clethra, and Suborders, PYROLEAE and MONOTROPE^).
The petols are also nearly distinct, in the genera Ilex and Prinos, of the ORDERLY.
AQUIFOLIACE^.

The plants belonging to ORDER XL. CUCURBITACE^ although often gamopetalous,
•will be found in the dialypetaloos division; also some of the ORDER XXXIV. LEGU-
MINOSJE, — as in Trifolium, &c. Our native species of Fraxinus — belonging to ORDER
LXXIV. OLEAC&E, and arranged at the end of the GAMOPETAJLE— are destitute of petals.

CAPR1FOLIACEAE 113

Doctor DARWIN, also, refers to the delightful genus, in the fol-
lowing lines: —

" Fair LOMCERA prints the dewy lawn,
And decks with brighter blush the vermil dawn ;
Winds round the shadowy rocks, and pansied vales,
And scents with sweeter breath the summer gales ;
With artless grace and native ease she charms,
And bears the horn of plenty in her arms."

2. ]j. parviflora, Lam. Leaves deciduous, oblong, upper pair

connate, all others closely sessile; corolla gibbous at base, tube

short.

SMALL-FLOWERED LONICERA.

or 4 inches long, obtuse, very glaucous beneath. Flowers generally in single ter-
minal pedunculate heads, which are composed of 2 or 3 verticils : corolla yellowish,
with tinges of purple externally, — the tube about half an inch long, gibbous near

jvdicels bracteate at base. Corolla greenish-yellow.
Hob. llocky woodlands : frequent. Fl. June. Fr. Sept.

175. TRIOS'TEIIM, L.

[Gr. Treis, three, and Osteon, a bone ; from its 3 bony seeds, or nuts.]

114 GAMOPETALOUS EXOGENS

Obs. The root of this plant was formerly somewhat noted, as an
Indian medicine; but is now neglected. JOHN BARTRAM (in the
Appendix to SHORT'S Medicina J3ritannica,J says, it is "called in our
Northern Colonies Dr. Tinker's Weed; in Pennsylvania, Gentian;
and to the Southward, Fever-root."

3. T. angUStifftlilim, L. Bristly hairy; leaves lanceolate,
tapering to the base; axils mostly 1-flowered; flowers greenish-
yellow, sometimes tinged Avith purple.
NARROW-LEAVED TRIOSTETJM.

Stem 1 to 2 feet high, simple, rather slender, clothed with spreading and some-
what bristly hairs. Leaves 2 to 4 inches long, and % to 1% inches wide, the long
tapering base narrowed almost to a margined petiole, scarcely connate, — the mar-
gins of the leaves, bracts, and calyx-segments, ciliate-hairy. Corolla about % an
inch long, rather slender, glandular-pubescent.
Hab. East Nottingham : rare. Fl. May. Fr.

Obs. Collected in 1852, by Mr. EVAN PUGH, of East Nottingham.
This is probably the northern limit of the species.

smooth, petiolulate ; cymes flat, 5-parted ; fruit purplish black.
CANADIAN SAMBUCUS. Elder-bush. Common Elder.

Stem 5 to 8 or 10 feet high, suffruticose, and finally woody, nodose, branching. —
Leaflets 2 to 4 inches long, usually 3 pairs and an odd one.
Hab. Thickets; fence-rows, &c.: common. FL June. Fr. Aug.

Obs. This is a rather troublesome plant, to the farmer, — the
long roots being very tenacious of life, and inclined to spread ex-
tensively along fence-rows and hedges, and even into the fields.

3. S. pill>ens? MX. Leaflets 5 to 7, ovate-lanceolate, sometimes
pubescent beneath ; cymes at first convex, finally conical, or thyr-
Boid ; fruit bright red.
DOWNY SAMBUCUS. Red-berried Elder.

Stem 3 or 4 to 10 or 15 feet high, rather more woody than the preceding, branch-
ing. Leaflets 3 to 5 inches long, — usually 2 pairs and an odd one ; flowers greenish-
white,— often purple, externally.
Hab. Thickets; W. Nottingham: rare. Fl. April. Fr. June.

06s. This species — so common on our mountains, and so remark-
able for its thyrsoid inflorescence, and scarlet berries, which are
ripe by the time the other is in flower — has been detected in the
South-western extremity of the County, by Mr. NATHAN MILNER, —
as I learn from my friend JOSHUA HOOPES. In specimens which I
have growing, the leaflets are quite smooth on both sides.

CAPBIFOLIACEAE 115

inr. TiBiiR'ivuroi , L.

[A classical Latin name ; etymology obscure.]

Calyx 5-toothed. Fruit a 1-celled 1-seeded drupe, with scanty pulp,
and a crustaceous more or less flattened nut. Shrubs : leaves sim-
ple, petiolate ; flowers usually white, in flat compound mostly ter-

cles, covered with a ferruginous scaly pubescence. Drupes deep blue when mature,
punctate with white scaly dots.
Hab. Great Valley, and Valley hills : rare. Fl. May. Fr. Sept.

Obs. The variety, Cassinoides, of TORREY and GRAY ( V. pyrifolium,
Pursh.), — with obovate-lanceolate and rather smaller leaves — was
found in the South-western part of the County, in 1851, by Mr.
JOSHUA HOOPES.

2. V. pniliifolium, L. Leaves broadly oval, thhmish, ser-
rulate ; petioles with narrow even margins ; cymes sessile on lateral

4. V. dentsktum, L. Leaves orbicular-ovate, coarsely dentate ;
petioles not margined; cymes pedunculate; drupes subglobose,
mucronate.

DENTATE VIBURNUM. Arrow-wood.

verging ; petioles alxmt an inch in length, with 2 filiform stipuks at base. Flowers
often tinged with red. Drupes purplish-black, when mature.
Hob. Moist woodlands: very common. Fl. May. Fr. Sept.

Obs. The slender stems of this shrub, when the pith is removed,
afford good fuse-sticks, for blasting rocks ; and are much used for
that purpose. A species of this genus, commonly cultivated as an
ornamental shrub, is the Guelder-Eose, or "Snow-ball" ( F. Opulus,
£.), _ which the Poet COWPER so beautifully describes, as throwing

up its

- " silver globes, light as the foamy surf,
That the wind severs from the broken wave."

ORDER XLVIII. RUBIACEAE.

Herbs, or shrubs; leaves opposite, entire, connected by interposed stipule* ; or ver-
ticillate without apparent stipules;* calyx-tube mostly adherent to the ovary;
corolla regular, 3- 4- or 5-lobed; stamens as many as the corolla-lobes, and inserted
on its tube; styles mostly 2; fruit various; seeds with copious hard albumen.

This Order contains a number of important plants. Among the most interest-
ing, may be mentioned the Coffee plant (C<;ffea Jralica, L.)— the Peruvian Baric
tree (Cinchona officinalis, X.)— the IpecacuanJia (C.phadis Ipecacuanha, Rich.)— and
the Madder (Eubia Tinctorum, L.). The popular vermifuge, called Carolina Pink
(Spigelia Marilandica, L.~) — and the well-known beautiful and fragrant Cape Jessa-
mine (Gardenia florida, L.~)— are also referred to this comprehensive and somewhat
anomalous Family.

SUBORDER I. STELLAVTAE.

Leaves verticillate, without apparent stipules ; calyx-tube entirely adherent to the
ovary ; corolla-lobes valvate in the bud. Plants mostly herbaceous.

178. GAV]LI1TM, L.

[Gr. Gala, milk ; which some species were used to curdle.]
Calyx-teeth obsolete. Corolla 4- (rarely 3-) parted, rotate. Fruit
smooth, or uncinately hispid, roundish, dry or slightly fleshy, — com-
posed of twin 1-seeded indehiscent carpels. Slender herbs : stems
square, often retrorsely aculeate ; jloicers small, cymose.

§1. ANNUAL: Verticils about 8-leaved; peduncles axillary, few-flowered.

flowers white; fruit rather large, uncinately hispid.

Common Cleavers. Goose-grass. Robin-run-the-Hedge.

Stem 4 to 6 feet long; branches short. Leaves about an inch and half long, ses-
sile, tapering to the base, in rather distant verticils of 6 or 8. Flowers mostly on
axillary elongated peduncles.

Hob. Fence-rows, and shaded places. Nat. of Europe. Fl. May. Fr. July.
§2. PEREXXIAL: f Verticils mostly &-leaved ; flowers white.

2. Cr. asprellUMl, MX. Stem clambering, aculeate, usually
much branched and tangled ; leaves oval-lanceolate ; flowers very
numerous and small ; fruit usually smooth.

* That is, the " interposed stipules," in this case, are regarded, by some, as being
developed to the size, and in the/wwi, of the true leaves,— -and thus forming a ver-
ticil. Prof. LINDLEY, however, does not concur with this view; but considers all
the members of the verticils as genuine, leaves.

RUBIACEAE 117

ROUGHISH GALIUM.

Stem flaccid, 2 or 3 feet long (often 4 to 6 feet, when supported on bushes), very
rough and adhesive. leaves half an inch to 3 quarters in length, sometimes 4,
mostly 6, and 5, in a verticil. Flowering branches divaricate ; peduncles in pairs,
or threes, very slender, rather short.

long, in verticils of 5, or 6, — often in fours on the branches. Peduncles mostly in
threes, axillary or subterminal, slender, spreading.
Hub. Low grounds, and thickets : frequent. Fl. June. Fr. Aug.

Obs. The G. tinctorium, L. is now regarded as nothing more than
a variety of this. The roots of these were formerly employed, by
the Aborigines, for dyeing porcupine quills, and other savage orna-
ments, of a red color.

4. G. tri lift I'll in, MX. Stem reclining or prostrate, somewhat
aculeate; leaves elliptic-lanceolate, cuspidate; peduncles elonga-

ters wide, the lower ones often roundish-obovate. Peduncles nearly simple, finally
geniculatc. Corolla pale purple, or purplish-white.
Hab. Rich woodlands : frequent FL June. Fr. Aug.

Obs. This species is easily recognized by the sweet Liquorice-like
taste of the leaves. There seems to be a variety of it» of large*
growth, and almost as hairy as G. pilosum.

118 GAMOPETALOUS EXOGENS

•y. G. lanceol&tum, Torr. Stem erect, nearly simple, smooth;

pering to a narrow point, but rather obtuse at apex. Peduncles frequently trichot-
omous.
Hob. Rocky banks of Schuylkill : rare. FL July. Fr. Sept.

Obs. The root of this is said to dye a red color. The RUBIA
TINCTORTJM, L. or Madder, — a plant nearly allied to Galium, and a
well-known Dye, — is cultivated in the West; and may be occasion-
ally seen in gardens : but it is scarcely entitled to a place in our
Flora.

Involucre many-leaved, longer than the bracts (or subfoliaceous
ehaff) of the receptacle : Florets each with a 4-sided calyx-like invol-
ttcel closely investing the ovary and fruit. Jlorder of the calyx
ininute, cup-shaped, entire. Corolla with 4 erect lobes. Stout bien-
Viials: leaves often connate; heads ovoid-oblong, — the florets com-

who would keep his premises in neat condition. Doctor DARWIN
thus indulges his imagination, in reference to its supposed thirsty
character: —

" When droops the sickening herb, the blossom fades,

And parch'd earth gapes beneath the withering glades, —

With languid steps fair DIPSACA retreats,—

' Fall, gentle dews!' the fainting nymph repeats;

Seeks the low dell, and in the sultry shade

Invokes, in vain, the Naiads to her aid."

bracts, on the mature heads, being used as a kind of card, to raise
the nap on woollen cloth.

ORDER LI. COMPOS'ITAE.

Mostly herbs ; leaves alternate, or opposite, often lobed or dissected, never truly
compound, and not stipulate; flowers in close heads, — composed of many florets
(perfect or imperfect) upon a common receptacle, and embraced by (mostly numer-
ous) leaflets, or scales, which form a general involucre; calyx-tube closely adherent
to the ovary,— the limb, or border, of the calyx (called pappus), consisting ofJiairs,
awns, or scales, or sometimes obsolete; corolla either tubular and 5-lobed, or ligu-
late and 6-toothed ; stamens mostly 5, inserted on the corolla, — the anthers united,
forming a tube round the style, which is 2-cleft at summit, with stigmatic glands,
in lines, on the inner surface of the branches; fruit an akene, containing a single
erect seed destitute of albumen,*

* This Order is so natural, and at the same time BO enormously large (containing
between 800 and 900 genera, with species almost innumerable), that it is difficult
to discriminate, satisfactorily, among such kindred multitudes. The Botanists,
consequently, have been obliged to seize upon any features— however small, or
inconspicuous — that are constant, and will serve the purpose : hence, they have re-
gorted to such minute characters aa are afforded by style-branches, stigmatic lines,
anther-tails, Ac. The student will, therefore, do well to make hhnself familiar with
these nice distinctions.

199. AMBROSIA, Tournef.

[Poetically, Food of the Gods; a name singularly inappropriate tt> our plant.]
Heads monoicous, — the staminate ones 5- to 20-flowered, in terminal
racemes, — the pistillate 1-flowered, in bracteate clusters of 2 or 3
to 5, sessile at the base of the racemes, or in the axils of the upper
leaves. Involucre of the staminate heads flattish ; scales several,
united into a cup ; florets all funnel-form. Involucre of the pistillate
florets turbinate, closely embracing the akene, like a utricle, acumi-
nate, with 4 to 8 (usually 5 or 6) pointed tubercles near the sum-
mit. Corolla none. Akene obovoid. Chiefly annuals : leaves
opposite and alternate, petiolate, lobed or pinnatifidly dissected.

strongly 5- or 6-ribbed, — the ribs with as many acute points at top.
Hob. Low grounds; waste places, &c. : frequent. Fl. Aug. Fr. Octo.

Obs. A coarse homely weed, and frequent enough, — but not so
abundant as the following species. If the generic name has refer-
ence to the mythological Ambrosia, it must be something like Lucus,
a non lucendo ! I should have supposed it more likely to have been

the authorities are otherwise.

Stem 1 to 3 or 4 feet high, usually bushy. Leaves 2 to 4 inches long; petioles %
of an inch tt> an inch in length, mostly ciliate with long white hairs. Staminate
Jieads small, in terminal slender spicate racemes. Pistillate florets in axillary
bracteate clusters, below the staminate racemes : sometimes the heads are dimcous,
— i. e. the terminal racemes (or rather interrupted spikes, in that case,) — as well as
the clusters beneath, — are all pistillate! and the flowers in small sessile bracteate
clusters. Involucre of the pistillate florets scarcely ribbed. Akene mucronate, dark
brown.
2 lab. Cultivated fields, and pastures : common. Fl. Aug. Fr. Octo.

Obs. This worthless weeH is apt to spring up wherever the ground
is broken with the plough,— and to be particularly abundant among
the stubble, after a crop of wheat: but, if the land be good, the
plant seems to be smothered- or choked out, the next season, by the
clover and grasses.

i aches long. Heads of flowers in axillary racemose clusters, — the pistillate ones at
the base of the racemes.
Sab. Farm-yards; roadsides, Ac. Nat of Europe. Fl. Aug. JFV. Octo.

mostly solitary.

Hob. Farm-yards, and waste places. Nat. of Europe. Fl. Sept. Fr. Octo.

Obs. This execrable foreign weed has found its way into our
County, but is happily yet rare ; and it behooves every good citizen
to extirpate it, wherever it may appear. Some years since, the
authorities of on.e of our cities — where it was becoming a great
nuisance, in the streets — enacted an ordinance against the plant, —
denouncing it by the name of Canada Thistle! The misnomer
probably did not impair the efficacy of the ordinance : But it would
be more reputable to all concerned, if they could avoid confounding
objects which are essentially distinct, — -and learn to designate even
weeds by their proper names.

In gay solemnity his Dervise-trains ;

Marshal'd in Jives each gaudy band proceeds,

Each gaudy band a plumed Lady * leads ;

And bows in homage to the rising dawn;

Imbibes with eagle eye the golden ray,

And watches, as it moves, the orb of day."—

plants of this class are furnished with a plume, by which admirable mechanism,
they are disseminated by the winds far from their parent stem, and look like a

ily for the Poet's Botany, is not at all applicable to the pappus of Hdianthus.

Obs. The whole herb is a fine aromatic bitter, —-particularly the

plant thrives better for being trampled upon, or kept prostrate, —
whence it was popularly called ^the Whig Plant" during the revo-
lutionary contest, in the United States. The notion is thus inciden-
tally alluded to, by SHAKSPEARE, in the first part of King Henry
IV. — " For though the Camomile, the more it is trodden on the
faster it grows — yet youth, the more it is wasted the sooner it
wears."

Hob. Fields, and meadows. Nat. of Europe. FL June. Fr. Aug.

Obs. This foreigner is a great nuisance, on the farms in Eastern
Pennsylvania, — especially in the vicinity of Philadelphia, where it
has abounded for more than a century, and seems likely still to
prevail. JOHN BARTRAM, in his Correspondence, speaks of it as "a
very destructive weed, in meadow and pasture grounds, choking
the grass and taking full possession of the ground, so that the fields
will look as white as if covered with snow ; but (he says) the hoe
and plough will destroy this weed." No doubt, those implements,
adequately .applied, might abate the nuisance ; but so long as there
are negligent, slovenly farmers among us, it will be vain to hope
for its thorough extirpation.

but it is evidently a stranger in this County ; and our farmers would
do well to keep it such.

Obs. This foreigner (which, from the common name, seems to
have reached us by way of Canada,) is justly regarded as one of the
vilest vegetable pests that has yet invaded our country. It is, hap-
pily, yet rare in Chester County; and ought to be most vigilantly
watched, and promptly extirpated whenever it makes its appear-
ance.

Obs. This foreigner — although not a very obnoxious weed — is
more abundant than welcome ; and is, moreover, difficult to get rid
of, — as myriads of seeds are annually wafted over the country by

Obs. This is also a showy plant, when in bloom, — next in rank,
among our indigenous species, to the preceding. It was, formerly,
a famous Indian Nostrum, — and had such repute, that the secret was
purchased of the Aborigines : but, when once known, it soon shared
the usual fate of purchased Nostrums ; and possibly — like all exag-

duly disparaged.

Chiefly shrubs ; leaves mostly alternate, without stipules ; flowers regular, or nearly
so ; corolla 4- or 5-lobed (rarely 4- or <j-petaled) ; stamens as many, or twice as many,
as the lobes or petals ; anthers often with awn-like appendages, and frequently
opening by pores at summit ; style 1 ; ovary 4- to 10-celled ; fruit a berry, or cap-
sule ; seeds with fleshy albumen.

This is an interesting Order,— comprising some plants of a medicinal character,
and a number that are exceedingly beautiful — especially the Azaleas, Rhododen-
drons, Kalmias, and many species of the multitudinous genus (Erica} which is the
type of the Family. The Rhododendrons recently collected on the Himalaya
mountains, by that enterprising and accomplished Botanist, Doctor J. D. HOOKEB,
are among the most magnificent of ornamental trees and shrubbery.

,&§=" The prevailing under-shrubs in our forests,— namely, the Gaylussacias, Vac-
ciniums, and Andromedas,— seem to take the place, on this Contineni>-and may
be regarded as the Phytognostic Equivalents — of the Ericas of the Eastern hemis-
phere.

CLAMMY AZALEA. Sweet Wild Honeysuckle.

Stem 4 to 6 feet high, with short spreading and often crooked branches above. —
Leaves 1 to 2 inches long, the margins and midrib bristly ; petioles 1 to 2 lines in
length. Corolla white,— the tube much longer than the lobes.

Hob. Rocky woods; N. Valley-hill; New Red Lion: not common. Fl. June. Fr.
Obs. This species is readily known by its white, clammy, sweet-
smelling flowers. The large terminal buds, which are formed in
autumn, on the Azaleas, and some other members of this family,
contain the flowers of the ensuing year, perfectly formed — though in
miniature. Something like this seems to be the fact, in all trees in
which the branches have a definite annual development of wood,
leaves, and flowers ; such as the Horse-Chestnut, &c. The buds of
the Firs, also, contain the undeveloped branches of the succeeding
year, with all their tiny leaves completely formed, and closely
packed together. The phenomenon is happily noticed by the Poet,
COWPER: —

" The beauties of the wilderness are His,
That make so gay the solitary place,
Where no eye sees them. And the fairer forms,
That cultivation glories in, are His.

ERICACEAE 171

HE sets the bright procession on Its way,

And marshals all the order of the year;

HE marks the bounds which Winter may not pass,

And blunts his pointed fury ; in its case

Russet and rude, folds up the tender germ,

Uninjured, with inimitable art ;

And ere. one flowery season fades and dies,

Designs the blooming wonders of the next"

inches long, crowded at the extremities of the branches, margins hairy, pubescent
beneath ; petioles % to % an inch in length. Corotta varying firm pale flesh-color
to pink, and bright purple, — the tube scarcely longer than the lobes.
Hob. Moist woods, and thickets: common. Fl. April. Fr. June.

Obs. This pretty shrub is a striking ornament of our forests, in
spring. It was rather carelessly stated, in the preceding edition of
this Flora, that "the leaves" of this shrub "are subject to large
green succulent excrescences, produced by the puncture of insects." —
In 1842, Mr. BENJAMIN V. MARSH, then of Haverford School, Del.
County, satisfied me that I was incorrect, and that those "excres-
cences" are formed of the flowers of the plant, instead of "the
leaves." A closer observation has also led me to doubt whether
"insects" have any agency in their production. I find those suc-
culent masses invariably to consist of what seem to be a sort of
dropsical enlargement of calyx, corolla, stamens and pistil, — by which
the floral organs are all consolidated, or blended together; and
their original individuality, and character, entirely lost, — except
some vestiges of anthers and stigma.

Obs. KALM says the Swedes called this "Spoon tree," — because
the Indians made spoons from its wood. With great deference to
the decision of LINNAEUS, this genus of beautiful Evergreens is the
one which, in my humble opinion, ought to have commemorated
the merits of JOHN BARiRAM,-r-the Botanical Patriarch of our

or shrubs; leaves (in our genera) alternate ; stipules none ; flowers axillary,

small, of 4 to 6 parts, often pdygamodioicous ; calyx minute, free from the ovary ;
petals nearly distinct ; stamens as many as the petals, and attached to their base;
fruit a berry -like drupe, with 4 or 6 nutlets; albumen fleshy.

250. IXEX, L.

Dioicously polygamous: Flowers tetramcrous, — i. e. the parts in
fours. Petals ovate-oblong, obtuse, slightly connected at base. —
Drupe with 4 or 5 striate or grooved nutlets. Leaves mostly coria-
ceous, evergreen, and spiny-toothed.

with minute bracts at base. Berries small, roundish-ovoid, red when mature, per -
sis tent.
Hdb. Woods ; Brandywine ; slaty hills : rare. Fl. June. Fr. Sept.

Obs. This becomes a handsome little tree under cultivation ; but
is small, and scarce, in its wild state, here. The European Holly
(/. aquifolium, L.) is a more showy species, — with the leaves and
berries of which, says SirW. J. HOOKER, " our houses and churches
are adorned at Christmas, a relic probably of Druidism." Dr.
DARWIN thus notices the formidable character of its foliage, in his
Botanic Garden: —

" Four of the giant brood with ILEX stand,
Each grasps a thousand arrows in his hand ;
A thousand steely points on every scale
Form the bright terrors of his bristly mail."

251. PRriVOS, L.

[The ancient Greek name of the Holly.]

Dioicously polygamous : Flowers hexamerous, or the parts mostly in
sixes. Corolla subrotate, deeply lobed. Drupe with 6 smooth nut-
lets. Leaves mostly deciduous, serrate.

1. P. verticill£tos, L. Leaves oval and obovate, acuminate;

Stem 6 to 8 feet high, much branched. Leaves 2 to 3 inches long; petioles about
half an inch in length. Flowers greenish white, — the sterile umbels pedunculate,
the fertile clusters smaller, and nearly sessile; pedicels about % of an inch in
length. Berries globose, in small axillary clusters (2 or 3, often 1, in an axil.)
appearing somewhat verticillate, bright red when mature, persistent.
Hob. Low, swampy grounds, and thickets : frequent. Fl. June. Fr. October.

Obs. An evergreen species, with black fruit (P. glaber, L.), is
common !JQ New Jersey ; but has not been found in Chester County.
This genus is nearly allied to Ilex, — and Mr. ELLIOTT suggested the
propriety of uniting them. ENDLICHER uses nearly the same words,

176 GAMOPETALOUS EXOGENS

in describing the two, — and DE CANDOLLE asks, under Prinos, "an
ab llice satis differt?" — The bark of the species here described, used
in decoction, has long been a popular remedy for ill-conditioned
sores, — administered both externally and internally.

ORDER LVI. EBENACEAE.

6-lobed. Stamens, in the sterile flowers, usually 16, — in the fertile,
8 imperfect ones. Berry 4- to 8-celled, large, globular, — the per-
sistent calyx mostly adhering to its base. Flowers axillary, sub-
sessile, — fertile ones solitary, sterile ones mostly in threes,

long, subcoriaceous ; petioles % an inch to near an inch in length* Corotta
jochroleucous, obtusely 4-angled. Berry about an inch in diameter, reddish-orange
when mature.
Hob. Low grounds; along streams: frequent. Fl. June. Fr. November.

Obs. The fruit, when ripe, is sweet and luscious, after being sub-
jected to the action of frost, — but is remarkably harsh and astrin-
gent, in its green state. The bark of the tree is astringent and
tonic. The well-known hard black wood, called Ebony, is furnished
by D. Ebenum, and some other species of this genus.

Obs. A naturalized foreigner, — remarkable for accompanying
civilized man; growing along his footpaths, and flourishing around
his settlements. The leaves are a convenient and popular dressing

cylindric. Bracts ovate, acuminate, — the slender point finally reflexed. Calyx
apparently of 3 sepals, — two being united into one. Stamens several times longer
than the corolla ; anthers greenish-white. Xeeds oblong, convex on one side, con-
cave on the other, shining, brown or amber-colored.
JIab. Pastures, &c. Nat. of Europe. FL May. Fr. July.

Obs. This species, also, is extensively naturalized,— and more
abundant than welcome, in our upland meadows and pastures. Al-
though eaten by Stock, generally, it is much disliked by the farm-
ers: yet, I apprehend, it will be found a very difficult plant to get
rid of, where once fully introduced.

ll.ib. Fields ; roadsides, Ac. Nat. of Europe. Fl. June. Fr. Aug.

Obs. This humble foreigner is gradually extending itself through
our country. It has been remarked, in Europe, that if the flowers
are expanded in the morning, the day will prove fine, — if shut, the
contrary ; and hence it has been named the " Shepherd's Weather*
glass." Popular credulity has given to this inert little herb some
notoriety, as a medicine. It is one of the old specifics for Hydropho-
bia ; and so late as the year 1802, grave Senators of Pennsylvania
requested their Speaker to present the thanks of the Senate to an
aged German, for communicating to that body sundry particulars
about the plant, and its virtues, which had been published to the
world, over and over again — in that Farrago of Trumpery, the
Jfnteria Medica of the olden lime — long before any of those worthies
were born!

Obs. This singular plant is remarkable for being found (like VIR-
GIL'S Shepherd) "sub tegmine Fagi" — and seems to be confined to
the roots, or immediate vicinity, of Beech trees. MICHATJX says of
its habitat — "inradice FAGI, nee aliae plantae"; nor have I ever
seen it growing elsewhere. It is considerably astringent, — and
was formerly in some repute, in the hands of cancer Doctors, and
other dealers in infallibles.

become naturalized in several localities ; though I think it is clearly
not indigenous, here, — but was probably introduced from the South,
as an ornamental shade-tree.

ORDER LXIII. SCROPHULARIA^CEAE.

Chiefly herbs; leaves alternate, opposite, or verticillate, without stipules ; flowers
pentandrous, didynamous, or diandrous; corolla irregularly 5-lobed, subrotate,
personate, or bilabiate, — the lobes imbricated in the bud ; stamens inserted on the
tube of the corolla; capsule 2-celled, mostly 2-valved, usually many-seeded; pla-
centae united in the axis ; embryo small, in copious albumen.

This Order comprises nearly 150 genera,^affording many curious and rather
handsome powers — some troublesome weeds — and a few plants of considerable me-
dicinal power, especially the purple Ibxglove (Digitalis purpurea, L.). The Fau-
lotvnia imperialis, of SIEBOLD and ZUCCARJNI — recently introduced from Japan, as

184 GAMOPETALOUS EXOGEXS

an ornamental sliade-tree — belongs here; though its general habit, or aspect, would
lead one to look feu it beside the Catalpa. It is scarcely, yet, entitled to a place in
our Flora.

SUBORDER I. ANTIRRHINID'EAE.

Upper lip of the corolla outermost, covering the lobes of the lower, in the bud;
capsule usually septicidal.

f Corolla subrotate ; leaves all alternate.

265. VERB AS'CIIM, L.

[Quasi Barbascum: Latin, Burba, beai-d; from its bearded, or woolly habit.]
Calyx 5-parted. Corolla nearly equally 5-lobed, concave-spread-
ing. Stamens 5, declined; filaments unequal, all (or the 3 upper
ones) hairy. Capsule ovoid, or globose; seeds rugose- pitted. —
Chiefly biennials : flowers in dense spikes, or paniculate racemes.

1. V. Thdpsus., L. Densely hoary-tomentose ; stem stout, simple;
leaves lance-oval, entire, the cauline ones decurrent; flowers in a
thick dense terminal spike; 2 lower filaments smooth.

THAPSUS VERBASCUM. Common Mullein.

Plant pale greyish-green ; pubescence much branched. Stem 3 to 6 feet high. —
Radical leaves 6 to 12 inches long, entire, subsessile; stem-leares smaller. Spike 6
to 12 or 15 inches long, cylindric, about an inch in diameter; flowers subsessile,
bracteate, bright yellow.
Hab. Neglected fields ; roadsides, &c. Fl. June. Fr. Aug.

Obs. This foreigner (common throughout Europe, though named
as if originating in the isle of Thapws,) is abundantly naturalized
in all our older settlements ; and its prevalence is one of the certain
signs of a negligent slovenly farmer. The plant seems apt to hy-
bridize,— or, at least, subject to some remarkable varieties; as I
have occasionally found it with the spike less dense, the bracts
larger, the stem-leaves ovate and acuminate, with one or more
pedunculate flowers in the axil of nearly every leaf: possibly a cross-
breed from V. Lychnitis, L. which is frequent around Philadelphia.

2. V. Blattaria, L. Smoothish and green; stem rather slender,
often branched; leaves oblong, serrate, not decurrent; flowers ra-
cemose ; filaments all hairy.

MOTH VERBASCUM. Moth Mullein.

loioer ones petiolate, often sinuate-pinnatifid, the upper ones sessile and clasping.
Kacune 6 to 18 inches long, leafy or bracteate, glandular-pubescent; pedicels % an.
inch to an inch in length ; flowers greenish-white with a tinge of purple, or bright
yellow.

Obs. The variety with whitish, purple-tinged flowers, has become a
common weed in Chester County ; the other is more rare. It ap-
pears, by the Bartram Correspondence, that about the year 1735,
PETER COLLINSON sent the seeds of the " Yellow Moth Mullein" to
JOHN BARTRAM, as a curiosity — among many others; and that is no
doubt the way the yellow variety came to be so common around
Philadelphia. This species was named under the notion (which
requires confirmation,) that it possessed the virtue of expelling
Moths from among clothing.

nating the stem, and branches; corolla pale greenish-yellow, — the palate bright
orange-color; throat villous; spur subulate, about half an inch long. Capsule
ovoid-oblong; seeds with a dilate! orbicular margin.

Obs. This showy, but worthless, and prevalent weed, is said to
have been sent from Wales, as a garden flower, to a Mr. Ranstead,
of Philadelphia. JOHN BARTRAM, writing of the troublesome plants,
in Pennsylvania, near a century since, says — "The most mischiev-
ous of these, is the stinking yellow Linaria. It is the most hurtful
plant to our pastures that can grow in our northern climate. Neith-
er the spade, plough, nor hoe, can eradicate it, when it is spread in
a pasture. Every little fibre that is left, will soon increase prodigi-
ously; nay, some people have rolled great heaps of logs upon it,
and burnt them to ashes, whereby the earth was burnt half a foot
deep, yet it put up again, as fresh as ever, covering the ground so
close as not to let any grass grow amongst it; and -the cattle can't
abide it," This is rather stronger testimony than I am prepared to
bear against the plant ; but it is certainly a monopolizing and most
unwelcome intruder, on our farms, — and requires persevering efforts
to get rid of it. Specimens of that remarkable form of the flower,
known by the name of Peloria — with a regular 5-lobed corolla, 5
spurs, and 5 perfect stamens — are occasionally to be met with. —
They are frequently, if not always, late flowers, — situated at the
summit of the raceme of full-grown capsules, and apparently the
latest floral developments of the plant. Sometimes these Pelorias
are tetranierous ; i. e. the corolla is 4-lobed, with 4 spurs, and 4
stamens. Altogether, the phenomenon is an interesting illustration
of the curious metamorphoses to which the organs of plants are sub-
ject.

trichotomous, with subulate bracts at base; calyx resinous-dotted; corotta pale
purple, nearly twice as long &s the calyx.
Hob. Dry, slaty, woodland hills : frequent. Fl. July. Fr. Sept.

Obs. The infusion of this herb is a popular and pleasant bever-
age, in fevers. In the beginning of winter, after a rain, very curious
ribbands of ice may often be observed, attached to the base of the
stems, — produced, I presume, by the moisture from the earth rising
in the dead stems by capillary attraction, and then being gradually
forced out horizontally, through a slit, by the process of freezing.
The same phenomenon has been observed in other plants. See
obs. on Helianthemum, p. 27»

Medicina Britannica, a century since. This interesting plant, — which
commemorates one of the most diligent correspondents of LINNAEUS,
and the early, indefatigable, and devoted friend of JOHN BARTRAM, —
is thus fancifully referred to, in Dr. DARWIN'S Poem, the Botanic
Garden: —

" Two brother swains, of COLLIN'S gentle name,
The same their features, and their forms the same,
With rival love for fair COLLINIA sigh,
Knit the dark brow, and roll the unsteady eye.
With sweet concern the pitying beauty mourns,
And soothes with smiles the jealous pair by turns."

Obs. Becoming a rather too common weed, on our farms. The
dried Herb, in infusion, is a highly popular medicine, with the
good ladies who deal in simples. DE THEIS, in his Glossaire de Bo~
tanique, has the following: — "Le gout des Chats pour cette plante
est tres-remarquable ; ils la mordent, 1'arrachent, et se roulent des-
gus avec transport. II est cependant singulier qu'ils ne s'attaquent
qu'a celle que Ton plante, et nullement a celle qui n'a point 6t6
deplace'e. De la le proverbe anglois —

" If you set it, the Cats will eat it ;
If you sow it, the Cats wont know it."

I doubt, however, whether our American Cats have yet learnt to
make the distinction, — or even acquired "le gout pour cette plante."

under the upper lip; anthers approximated in pairs, ciliate, — those
of the lower pair halved. Chiefly perennials : bitter instead of aro-
matic; flowers racemose, or solitary, terminal, or axillary. This
remarkably natural genus is easily recognized, by the concave disk-
like, or galeate, appendage of the calyx.

Hob. Swamps ; ditch banks, Ac. : frequent Fl. July. Fr. Sept.

Obs. Some years since, this plant had much notoriety, in conse-
quence of the assertions of Empirics, and some of their partizan
newspaper-editors, that it was a sovereign remedy for Hydrophobia •
and those contemporaries who ventured to doubt, were unsparingly

210 GAMOPETALOUS EXOGENS

denounced for their want of faith. Like its numerous predecessors,
of similar pretensions, the vaunted Specific had its day of importance
among the credulous, — and then sank into the oblivion which neces-
sarily awaits all such preposterous claims upon the public confi-
dence.

Bab. Roadsides. Nat. of Europe. Fl. July. Fr. Sept.

Obs. This foreigner has probably escaped from the Garden of the
late HUMPHRY MARSHALL ; and seems likely to become one of those
unprofitable additions which Botanic Gardens do sometimes make
to the vegetation of a country. In truth, some caution is required,
in introducing worthless plants into Agricultural districts, — other-
wise much mischief may be done.

Bab. Moist, shaded grounds : frequent Fl. July. Fr. Aug.

Obs. An intelligent practical farmer, a few years since, brought
to me specimens of this plant, — as one which he had found to be a
very pernicious weed, and difficult to get rid of. Whether others

214 GAMOPETALOUS EXOGENS

have had a similar experience of it, I am not informed. So far as
I have observed, the plant is generally confined to fence-rows, and
the low shaded grounds along streams.

ORDER LXVL BOR'AGINACEAE.

Chiefly hirsute herbs; stems round; leaves alternate, entire, not aromatic ; stipules
none; flowers usually regular, and nearly symmetrical, mostly in one-sided
racemes, or spikes, which are revolute (circinnate, or scorpioid) before development ;
calyx 5-parted ; coroUa 5-lobed, with 5 stamens inserted on the tube ; ovary deeply
4-parted, becoming in fruit 4 seed-like nutlets, surrounding the base of the style ;
seeds single, pendulous, with little or no albumen.

An order, for the most part, of rough homely plants, — some of them very ob-
noxious weeds. Several species have showy flowers; and some of the Heliotropt*
are admired for their fragrance.

f Corolla irregular.

310. EXCHIUM, Tournef.

[Gr. Echis, a viper ; the nutlets somewhat resembling a viper's head.]

little incurved, rough with greyish-brown tubercles.
Sab. Fields, &c. Nat. of Europe. Fl. June. Fr. Aug.

Obs. This showy, but pernicious weed, is gradually making ita
way into various sections of our County. It was detected in the
vicinity of West Chester, during the past summer (1851), by Misa
HARRIET HARLAN, a Teacher of Botany in PRICE'S Female Seminary.

rarely purplish ; scales of the throat glandular-dentate.
Hub. Gardens. Nat. of Europe. Fl. June. Fr. Aug.

Obs. This was formerly found in many of our gardens, — and is
yet, occasionally, to be seen, — for the sake of its mucilaginous
root, — which was reputed medicinal, for wounds, and internal com-
plaints. It is, doubtless, about as sovereign as "Parmaceti, for an
inward bruise."

* * Nutlets with a small flat scar at base.

will probably give our farmers much trouble, if they do not care-
fully guard against it. Incessant vigilance is said to be the condition,
on which alone the rights of Freemen can be maintained; and I

believe the Farmer will find a similar condition annexed to the
preservation of his premises from the inroads of pernicious weeds.
This plant has proved to be a most obstinate nuisance, in the culti-
vated grounds of England; and I may add, that I have not yet
Seen it thoroughly extirpated from any locality, here, — where it had
once got possession of the soil.

dilated, forming a kind of monstrosity. Leaves 2 to 4 inches long; petioles about
2 inches in length. Corolla purple (fide CHOISY, in DC.).
Sab. Gardens, and lots. Nat. of the Indies. Fl.

Obs. This plant is cultivated to some extent, in Chester County,
for its sweet tuberous rhizomas ; but the sandy soil of New Jersey
seems best adapted to their perfection. I believe it has never
/Lowered, in this region, — but is always propagated by cuttings, or
buds, of the tuberous rhizomas. It is said to be the Potato, spoken
of by writers of the Elizabethan age ; the Solanum tuberosum, L.
or "Irish Potato," so called (and now so common), being then
scarcely known in the old world. KALM states, — "that species of
Convolvulus which is commonly called .Batatas, has here [viz. Penn-
sylvania,, in 1748,] the name of Bermudian Potatoes." That name
is certainly, now (1852), quite obsolete. CHARLES BRYANT, in his
Flora Diaetetica, published in 1783, says — "The Batatas is a native
of both Indies, but has been a long time cultivated in Spain and
Portugal, whence the roots are annually imported." And he adds,
"these are certainly the same species of roots as those which
COLUMBUS'S Sailors were treated with by the inhabitants of Cuba,
and which they said were very sweet, and when boiled tasted like
Chestnuts."

Hob. Moist, low grounds; along streams: frequent. FL Aug. Fr. Octo.

Obs. This remarkable parasite — somewhat resembling copper
wire, in appearance, — seizes upon any herb within its reach ; but is
most usually found clinging to such neighbors as Imp aliens, Lycopus,
Boehmeria, and Mentha viridis. The Genus comprises a number of
species, — and has been ably investigated by that acute and learned
Botanist, Dr. GEORGE ENGELMANN, of St. Louis, Missouri.

SOLANACEAE 225

Obs. This plant — which became known to Europeans about the
year 1560 — though sparingly cultivated in Chester County, is a
staple article among the Planters of several Southern and Western
States. The commercial importance which this nauseous and pow-
erful narcotic has acquired, — together with the modes, and extent,
in which it is employed to gratify the senses, — certainly constitutes
one of the most remarkable traits in the history of civilized man. —
Were we not so practically familiar with the business, we should,
doubtless, be disposed to regard the whole story of the Tobacco
trade — and of the uses made of the disgusting herb — as an absurd
and extravagant fable. In view of the facts and circumstances, it
does seem like sheer affectation, on our part, to pretend to be as-
tonished at the indulgence of the Chinese, and other Asiatics, in
the use of Opium. The habitual use of Tobacco is always more or
less injurious to the system — especially the nervous system; and
in many instances it is highly deleterious. I speak from long ob-
servation, and personal experience, — having smoked and chewed the
herb, until its pernicious effects compelled me to es-chew it altogether.

325. DATITRA, L.

[Supposed to be from Tatorah, — the Arabic name of the plant.]
Calyx tubular, prismatic, separating transversely above the base,
in fruit. Corolla funnel-form, — the border plicately 5-toothed.— -
Stamens included. Stigma 2-lipped. Capsule oval, or subgloboee,
mostly prickly, 4-valved, 4-celled at base, 2-celled at summit. —
Seeds subreniform, roughish-dotted. Coarse annuals, fetid when
bruised: leaves somewhat in opposite pairs; flowers large, solitary,
axillary or dichotomal, on short peduncles.

In var. Tatula). Leaves 4 to 6 or 8 inches long ; petioles 1 to 3 or 4 inches in length.
Calyx prominently 5-angled, nearly half as long as the corolla, deciduous, leaving
the persistent base orbicular. Corolla about 3 inches long, ochroleucous (pale
Ttolet-purple in var. Tatuld). Capsule about an inch in diameter.
Hob. Waste places : introduced. Fl. July. Fr. Sept.

Obs. The variety, Tatula — with dark purple stems, and purplish
flowers, — is the one which prevails in Chester County ; though the
other is common in and around Philadelphia, — and is gradually
extending in this direction. It is generally put down as a native of
America ; but I strongly suspect it is of Asiatic origin, — and am
very confident it is a stranger in this region. The herb, and seeds,
are powerfully narcotic poisons, — and therefore, no doubt, potent
medicines, when properly administered ; but the plant is regarded,
and treated, as an obnoxious weed, by all neat farmers.

mature, clammy. Peduncles of the fruit about an inch long.
Hob. Roadsides, fields, and fence-rows: frequent. Fl. July. Fr. Sept.

Obs. The P. lanceolata, of the preceding edition, being somewhat
uncertain, — and having never found it, myself, — I prefer leaving it
for some future investigator to determine whether it really belongs
to our Chester County flora.

/ZoA. Gardens, and fields. Nat. of S. America. Fl. June. Fr. Sept.

Obs. This most important plant is known, and cultivated for its
esculent tuberous rhizomas, by every occupant of land. It has be-
come one of the indispensable crops, for a family. Long culture
lias, of course, produced tubers of various color and quality. —
BBYAST (in his Flora Piaetetica, 1783,) says, "the com-

mon Potato is a native of Peru, in South America. It has been
introduced into England about a century and a half, but was
amongst us a long time before much attention was paid to it, nor
did it come into use in the families of the higher class of people,
till within a few years past."

few-flowered, extra-axillary, nodding. Corolla white, small. Berries about % of
an inch in diameter.
Hub. Waste places. Nat. of Europe. Fl. July. Fr. Sept.

Obs. The books enumerate a var. Virginicum, — as though it were
indigenous ; but I am pretty well satisfied that our plant is a natu-
ralized foreigner. It is a worthless, disagreeable weed — reputed
poisonous, withal, — and ought to be expelled from the vicinity of
all dwellings.

3. S. Dulcamara, L. Somewhat shrubby and climbing; leaves
cordate-ovate, — the upper ones often hastate, or auriculate-lobed
at base; flowers in lateral cymes; fruit oval, small, red.

dots, or tubercles, at base. Berry near % an inch long.
Hob. About houses, &c. Nat. of Europe. Fl. July. Fr. Sept.

Obs. This has become naturalized in many places. The berric*
are poisonous ; and as their bright red appearance, when ripe, may
tempt children to eat them, the plant is not a desirable one, about
houses, or gardens.

§2. Stem and leares more or less prickly.

high, becoming somewhat woody at base. Leaves 4 to 8 or 9 inches long; petioles
1 to 3 inches in length. Peduncles sometimes dichotomous, bearing 2 flowers.—
GcfroUa Tiolet-purple, pubescent. Berries 3 to 6 or 8 inches in diameter. * ...
Hab. Gardens. Nat. of India. Fl. July. Fr. Sept.

Obs. Cultivated for the fruit. Long culture, as usual, has pro-
duced several striking varieties. The var. ovigerum, or true Egg-
plant, is nearly destitute of prickles, and bears a smaller white
berry, which exceedingly resembles an Egg : while tlie var. esculen-

SOLANACEAE 229

turn (which is most generally cultivated) is quite prickly, and bears
a dark purple berry, which sometimes attains to an enormous size,
and is roundish, or obovoid.

5. S. Carolinense, L. Stem suffruticose, branching ; leaves ovate-
oblong, acute, sinuate-angled and often subhastate, prickly on both
sides ; flowers in loose simple lateral racemes ; fruit globose, small,
orange-yellow.

armed with sharp spreading prickles. Leaves 4 to 6 inches long, stellately hirsute ;
petioles half an inch to 1% inches long. Racemes opposite to and often longer than
the leaves ; pedicels about half an inch in length ; corolla purplish or bluish-white.
Berries *4 to % of an inch in diameter.
Hob. Pastures, &c. Nat. of the Southern States. FL July. Fr. Octo.

Obs. This is an exceedingly pernicious weed, — and the roots so
tenacious of life that, when once fully introduced, it is almost im-
practicable to get rid of it. It was probably introduced from the
South, by the late HUMPHRY MARSHALL, into his Botanic Garden
at Marshallton, — whence it has gradually extended itself round the
neighborhood ; and strongly illustrates the necessity of caution, in
admitting mere Botanical curiosities into good agricultural districts.

ORDER LXXI. GENTIANACEAE.

Smooth herbs, with a colorless bitter juice; Zeaves mostly opposite, entire and sessile ;
stipules none ; flowers regular ; stamens as many as the lobes of the corolla, and
alternate with them ; anthers opening on one side; ovary formed of 2 united carpels,
1-cellcd, or half 2-celled, with parietal placentae; capsule 2-valved, septicidal,
many-seeded; seeds with fleshy albumen.

An Order containing many beautiful species, — and some of them valuable for

[Dedicated to Liberatus Sabbati ; an Italian Botanist.]

Calyx 5- to 12-parted. Corolla sub-rotate, 5- to 12-lobed. Anthers
at first erect, finally recurved. Style 2-parted, — the branches stig-

suture on each side.
Hob. Sterile old fields ; serpentine-rocks : frequent. FL July. Fr. Sept.

23f) GAMOPETALOTTS EXOGENS

Obs. This pretty plant is intensely bitter, and deservedly popular
as a tonic. The books speak of this, and all the other species, as
biennials, — and they may be so; but I confess that our plant always
appeared to me like an annual,

332. ERYTHRAEVA, Persoon.

[Gr. Erythros, red; in allusion to the color of the flowers.]
Calyx 2- or 5-parted ; segments slender, appressed. Corolla funnel-
form, slender; border 4- or 5-lobed, withering and twisting on the
capsule. Anthers exserted, erect, becoming spirally twisted.- —
Stigma 2-lipped, or sometimes capitate. Capsule sub-linear. An-
nuals : flowers in a dichotomous bushy panicle.

f f Style (if any) and stigmas persistent ; anthers straight.

BARTOVJVIA, Muhl.

[Dedicated to Prof. B. S. Barton, of the University of Pennsylvania.]
Calyx deeply 4-parted, appressed. Corolla subcampanulate, 4-
parted, destitute of folds, fringes, or glands. Stamens short. Ovary

closely sessile. Corolla about 2 inches long, bright blue, and beautifully fringed.
Seeds curiously echinate, or hispid.
Sab. Hilly open woodlands ; o^d fields, &c. : frequent. Fl. Octo. Fr. Noyem.

Obs. I have long suspected this autumnal beauty to be an annual ;
but was not aware, until recently, that PETER COLLINSON had en-
tertained the same suspicion, nearly a century before me. Authors
generally regard it as a biennial : which is it ?

J 2. PireiTMONANTftE : Corolla subcampanulate, or clavate, btobed, it>ith intermediate
plaited folds; anthers erect, sometimes cohering; seeds usually flat, and mar-
gined. Perennials.

2. €r. Sapoiiaria, L. var. pube*rula, Torr. $ Gray. Roughish-
puberulent; leaves narrow, sub-linear; corolla open, subeampami-
late.

SOAP-WORT GENTIANA (puberulent narrow-leaved variety).

long, varying from oblong-lanceolate to narrowly linear, often broader at base. —
Flowers clustered at summit, and more or less so in the axils; corolla, blue, about
an inch, or inch and half long ; anthers at first cohering, finally free ; seeds nar-
rowly margined.
Hob. Sandy grounds ; near New London : rare. Fl. Sept. Fr. Octo.

Obs. There has been much confusion respecting two or three of
our Gentians. The true G. Saponaria, of Linn, it appears, is a
Southern plant, — and is the G. Catesbaei, of Walter. Of this, there
are two varieties ; of which the puberula, of MX. is now regarded as
one. It was collected in the locality above named, in 1848, by Mr.
VINCENT BARNARD, an active and intelligent young Naturalist of
this County. The G. Saponaria, of FL Cestrica, ed. 2. is now G.
Andrewsii, of GRISEBACH — which see.

3. G> alba, Muhl. Smooth; leaves elliptic-lanceolate, and obo-
vate, closely clasping and slightly decurrent; corolla ventricose-
campanulate, finally open, — the lobes short and broadly ovate.

G. ochroleuca. Fl. Cestr. ed. 2. p. 165. not of FROELICH, nor GRAY.
WHITE GENTIANA.

Stem 9 to 15 inches high. Leaves 1 or 2 to 4 inches long, indistinctly 3-nerved,
Bubcoriaceous. Flowers mostly in a terminal bracteate cluster ; calyx-tube about
% an inch long, — the segments linear-lanceolate, % of an inch in length ; corolla
about an inch and half long, yellowish-white,— with tinges of pale green, or some-
times of purplish-blue ; outer lobes entire, inner ones serrate-dentate ; anthers finally
free ; seeds rather broadly margined.
Hob. Fields, and woodlands: not common. Fl. Sept. Fr. Nov.

232 GAMOPETALOUS EXOQENS

Obs. This has long been confounded with, or mistaken for, G.
ochroleuca; but Dr. GRAY has finally determined its character.

4. €r. Andre wsii, Griseb. Smooth; leaves ovate-lanceolate,

acute ; corolla ventricose-clavate, — the lobes and appendages con-

nivent, closing the mouth.

ANDREWS'S GENTIANA. Closed Gentian.

Stem 1 to 2 feet high. Leaves about 3 inches long, subconnate by a sheathing
membrane, 3-nerved, roughish on the margin. Flowers chiefly in a dense ter-
minal sessile fascicle, with' bract-like leaves at base, — often with few-flowered
pedunculate fascicles in the axils below ; calyx-tube half an inch long, — the seg-
ments lance-ovate, minutely ciliate, about half the length of the tube ; corolla 2
inches long, contracted and nearly closed at sunftnit, bright blue, paler in the
folds ; outer lobes very short, or obsolete, — the inner ones lacerate-serrate ; anthers
cohering ; seeds broadly margined.
Hob. Low grounds ; margins of Swamps : frequent. Fl. Sept. Fr. Nov.

Obs. This pretty species has long passed for G. Saponaria, among
the Botanists of the northern and middle States ; and, in fact, it
more nearly resembles Saponaria officinalis, in habit, than the one
named for it, by LINNAEUS.

SUBORDER II. OBOLARIEVAE.

Calyx 2-leaved; corolla-lobes imbricated in the bud; ovules covering the whole
inner surface of the ovary !

335. OBOLA'RIA, L.

[Gr. Obolos, a small Athenian coin ; from the form of the leaves.]

the base of the corolla, short; anthers sagittate, connivent, slightly
adherent to the stigmas. Ovaries 2, oblong, surrounded at base by
6 glands. Follicles in pairs, rigid, long and slender; seeds imbrica-
ted, linear, with a silky tuft (coma) at apex. Perennial herbs:
flowers in axillary or terminal paniculate cymes.

2. A. caiiiiabiuuili, L. Leaves lance-oblong, acute at each
end ; cymes many-flowered ; corolla-tube the length of the calyx, —
the lobes erect.

HEMP APOCYNUM. Indian Hemp.

Stem 2 to 4 feet high, smooth, purplish and a little glaucous, with rather erect
branches. Leaves 2 to 4 or 5 inches long, varying from ovate-lanceolate to linear-
oblong, acute, or conspicuously mucronate; petioles %to%&n inch in length.—
Cymes somewhat paniculate, one frequently dichotomal near the summit ; pedicels
with lance-linear bracts at base ; calyx-segments lanceolate, about as long as the
corolla-tube ; corolla mostly greenish-white, sometimes tinged with red. Follicles
as in the preceding, but more slender.
Ifab. Borders of woods; slaty hills: not common. Fl. Aug. Fr.

Obs. The bark of this species is said to afford a strong fibre, like
that of hemp : whence its common name.

ORDER LXXIII. ASCLEPIADACEAE.

Perennial herbs, mostly with a milky juice; leaves entire, usually opposite (some-
times verticillate, rarely scattered), stipules none ; flowers regular, pentamerous
and pentandrous ; corollarlobes mostly valvate in the bud ; filaments mostly dilated,
and connate in a tube, inclosing the pistils, — the tube augmented by a crown of 5
lobes, or scales, at summit ; anthers erect, united in a pyramidal 5-angled mass
which is truncate at apex, — each 2-celled ; cells opening perpendicularly, or trans-
versely ; pollen in waxy masses, which are attached, in pairs, to 5 small processes
at the angles of the stigma; ovaries 2; styles distinct, coalesced at summit, form-
ing a 5-angled stigma common to both; fruit & follicle; seeds imbricated, com-
pressed, mostly margined and comose ; albumen thin.

An Order remarkable for the peculiar structure of the flowers (well illustrated
in Prof. GRAY'S admirable Botanical Text Book), — and containing a number of
plants interesting to the curious ; though but few of any economical value.

337. ASCL,EVPIAS, L.

Hob. Low grounds; along streams: frequent. Fl. June. Fr. Sept.

Obs. This coarse species appears to have been named, by LIN-
NAEUS, under the mistaken impression that it was a Syrian plant;
but, being exclusively American, it has been deemed expedient to
correct the misnomer, of Syriaca, and substitute that of the man
who first noticed it in a history of Canadian plants.

urary 2-celled; fruit various, — baccate, drupaceous, samaroid, or capsular, by
abortion often 1-celled, and 1- or 2-seeded ; seeds mostly in hard fleshy albumen.

A small but interesting Order. Olives, and Olive oil, are afforded, by the drupes
of the genus (Olea) which is the type of the Family, — the fleshy pericarp chiefly
(" mcmorabili inter vegetabilia exceptione," DC.) yielding the oil. The Manna, of
tho shops, is obtained from a species of Ash (Fraxinus rotundifolia, Lam.).

or greenish).
Bab. Roadsides. Nat. of Europe. PL June. Fr. Octo.

Obs. This shrub was brought from England, by the early settlers
of Chester County, for the purpose of hedging; but it did not
answer. I recollect numerous vestiges of those early hedges, about
the close of the last century; but they have now (1852) all disap-
peared. The shrub, however, is naturalized to some extent.

341. CIIIOJVAtf'THUS, L.

gomewhat paniculate, — the terminal pedicels by threes. Petals white, nearly an
inch long. Drupes of a livid blackish color when mature.
Sab. Banks of West Brandy wine : rare. Fl. June. Fr.

Obs. The singular beauty of this ornamental little tree is begin-
ning to be appreciated, by our people; and it is, consequently,
making its appearance in the yards, and lawns, of all persons of
taste. The mature fruit has a remarkably disagreeable bitterish
taste, — and therein shows its affinity to the type of the Order. —
"Ripe olives," says Sir J. E. SMITH, in his Correspondence, "are
purple like a damson, but of the most abominable bitter taste."

b. Leaves odd-pinnate; fruit samaroid.

342. FRAX'KVITS, Tournef.

Obs. Naturalized on the banks of the Schuylkill, — but still rare.
The G. rhombifdlium, enumerated in FL Cestr. ed. 2. is now regarded
as a var. of C. firbicum, L. and is, moreover, a doubtful plant, in
our Flora.

34?. AMBRrtf A, Spach.

[Etymology not ascertained.]

Flowers nearly as in Chenopodium, — but the calyx-lobes not Jceeled,
the seed sometimes vertical, and the embryo, instead of forming a
complete ring round the albumen, curving merely in the form of a
horse-shoe. Styles often 3. Seed with an obtuse margin. Somewhat
glandular-pubescent and viscid (never mealy), and often exhaling a
strong balsamic odor; flowers greenish, racemose. All the species
here enumerated, if not foreigners, are evidently strangers in Chester
County.

Flowers in small clusters, disposed in slender naked racemes, or spikes. Styles 3,
united at base.
Hob. Roadsides; gardens, &c. Fl. July. JFV.Sept.

Obs. This is said to be a native of our hemisphere, — and even of
our Southern States. The herb has a strong unpleasant odor; and
the^seeds yield the well-known worm-seed oil, — a most unpalatable
but effective vermifuge; for which the plant is sometimes cultivated.

Obs. This well-known pot-herb is said to have been first brought
into Spain, by the Arabs ; thence diffused over Europe.

ORDER LXXVIII. AMARANTHACEAE.

Weed-like herbs; characters nearly as those of the preceding Order, — but the
flowers imbricated with dry scarious persistent bracts, which are usually colored ;
calyx of 3 to 5 sepals, dry, scarious and persistent; stamens as many as the sepals,
and opposite them ; fruit a utricle, 1- or several-seeded, bursting irregularly ; seeds
lenticular-reniform, often vertical; embryo curved round farinaceous albumen.

35O. AMARAWTHUS,* L.

[Gr. a, not, maraino, to fade, and anthos, a flower ; the flowers not fading.]
Monoicously polygamous : Calyx of 3 or 5 sepals, mostly colored,

* Several modern authors (as LINDLET, ENDUCHER, and MOQXJIN-TANDON) ar»
endeavoring to restore the orthography of RAY, — who, in his Historia Plantartfat
(fide MOQCIK, in DC. Prodr.), says " Amarantus maid cum th scribitur Amaranth** :
n»m graece est amarantos, Ac." But, as HOOKER, GRAY, and others, adhere to th«»
orthography which has been long established in our own language, — and whh
which we have become so familiar,— I have concluded to follow their example.

AMARANTHACEAE

and slightly connected at base. Stigmas 2 or 3. Utricle circum-
scissed, or indehiscent, 1-seeded; embryo forming a half circle round
the albumen. Coarse annuals : flowert minute, in axillary or ter-
minal spiked clusters.

1. A. dlbus, L. Pale green and smooth ; much branched ; leaves
gpatulate-oblong, retuse, setaceously mucronate; flowers whitish,
triandrous, in small axillary clusters.
WHITE AMARANTHUS.

Stem 1 to 2 or 3 feet high; principal branches from near the base, spreading.—
Leaves half an inch to 1% inches long, entire, narrowed at base to a slender petiok.
% of an inch to 1% inches in length. Bracts subulate-lanceolate, spinescently
acuminate, longer than the flowers.
Hdb. Waste places; barn-yards, &c. : frequent. Fl. Aug. Fr. Sept.

Obs. The books give this as a native of Virginia and Pennsylvania ;
but, to me, it has decidedly the appearance of a naturalized stran-
ger, in this County.

«8. A, hy'bridus, L. Roughish-pubescent; sparingly branched; dull
green; leaves lance-ovate; flowers green, pentandrous, clustered
in dense compound ovoid-oblong spikes.
HYBRID AMARANTHUS.

Stem 2 to 4 or 5 feet highk Leaves 2 to 5 inches long, tapering to the apex, but
the point rather obtuse, emarginate and setaceously mucronate, the base abruptly
narrowed to a petiole 1 to 3 inches in length. Flowers sometimes becoming pur-
plish, the staminate and pistillate intermixed. .
Hob. Gardens, and cultivated lots: abundant. Fl. Aug. Fr. Octo.

Obs. This, also> is given as a native of our continent; but I am
pretty well satisfied it is not indigenous, in Chester County. It is a
troublesome weed, in gardens, if not kept in due subjection.

3. A. spinbsus, L. Smoothish; bushy-branched; often purplish;
leaves rhomboid-lanceolate; axils spinose; flowers pentandrous,
clustered in compound oblong terete spikes.
THORNY AMARANTHUS.

mucronate, roughish-dotted, with glaucous blotches beneath; petioles about as
long as the leaves, with 2 subulate spines at base % to % an inch in length.
Hob. Waste places. Nat. of India. Fl. Aug. Fr. Octo.

Obs. This is a vile pest, — which has found its way to our sea-
ports, and is gradually extending itself into the country. It cannot
be too sedulously guarded against.

ORDER LXXIX. POLYGONAVCEAE.

Mostly herbs, with nodose stems; leaves alternate, usually entire, with stipules

peduncles; Flowers bright purple, rather large, crowded; pedicels rather longer
than the ciliate sheathing bracts.
Hob. Gardens, Ac. Nat. of Asia. Fl. July, Fr. Sept.

Obs. This showy species has become naturalized about our gar-
dens, and cultivated lots. JOHN BARTRAM probably refers to it, in
a letter to Miss GOLDEN, where he says — "The species of Persicary
thee mentions, is what TOURNEFORT brought from the three churches,
at the foot of Mount Ararat."

the lower ones on. petioles 1 to 3 inches in length; stipules tubular, — the lower ones
smooth, upper ones hirsute, Racemes few, dense-flowered, 2 to 3 inches long;
flowers bright purple; pedicels shorter than the hirsute sheathing bracts.
Hob. Margin of the Schuylkill: rare. Fl. Aug. Fr. Octo.

Obs. There are 1 or 2 pretty distinct varieties of this semi-aquatic
species, — partly, perhaps, owing to their places of growth ; being
found sometimes floating in pools, — at others radicating on the
mud, along their margin.

edges ; pedicels proceeding from bristly-ciliate sheathing bracts. Styles sometimes
2. Akenes opaque and roughish-dotted.
Hab. Moist waste grounds: introduced? Nat. of Europe. Fl. Aug. Fr, Sept.

Obs. I have a suspicion that this is but a naturalized weed, among
us. It would seem to be distinct from the P. punctatum, of ELLIOTT, —
with which I have heretofore confounded it. Dr. ENGELMANN,
writing to me, in October, 1847, says — Polygonum Hydropiper and
P. punctatum are two well-distinguished species; known from a
distance already by the heavy pendulous green spikes of the former,
and the light more distant-flowered erect whitish spikes of the lat-
ter ; this has, also, amongst other distinguishing characters, shining
smooth nuts, — the other opaque rough ones, &c. Both grow here
[St. Louis, Missouri] common."

Hob. Yards ; foot-paths, &c. Nat of Europe. Fl. June. Fr. Aug.

Obs. This humble weed is thoroughly naturalized, about our
dwellings. The P. erectum, L. $ Fl. Cestr, ed-. 2. p. 247. is now
generally regarded as a variety, — though pretty distinct in habit,
and of much larger growth. It is nearly erect, 1 to 2 or 3 feet high,
with oval petiolate leaves 1 to 2 inches in length, and yellowish-green
flowers. This variety has also been introduced from Europe ; and
inclines more to moist shaded grounds.

Hob. Fields. Nat. of Asia. Fl. Aug. Fr. Sept.

Obs. Extensively cultivated for its seeds, — the farinaceous albu-
men of which affords a savory article of food, in winter, when
properly managed. The English Botanists speak of it merely as
"an excellent food for poultry"; but, in Pennsylvania, we have
amended the statement, by substituting People for "Poultry." —
The glandular nectariferous flowers are a favorite resort of the
Honey-Bee.

Hob. Shaded rirulets, on the slaty hills : not common. Fl. April. Fr. June.

Obi. The soft pliable branches of this shrub are rendered so
tough and strong, by the bark, that they may be used as ligatures, —
whence the common name, Leather-wood.

ovary 1-celled, with 2 to 4 ovules suspended from the apex of a free central placenta ;
ttyle, 1 ; fruit always 1-seeded, indehiscent; embryo at the apex of copious albumen.
This order is chiefly remarkable for containing the fragrant Sandal-wood,— afforded
by species of Santalum.

358. COMAtf'DRA, Nutt.

[Or. Rome, hair, and Andres, for stamens; from the tufts attached to the anthers.J
Flowers perfect: calyx campanulate, 5-cleft, lined above the ovary
with a disk which has a 5-lobed free border, — the lobes of the disk
alternating with the calyx-lobes. Stamens inserted between the

i nch and half long, rather obtuse, sometimes acute, or mucronate. often narrowed
at base to a very short petiole. Flowers in small umbels, or fascicles of 3 to 5, with
involucral bracts at base, — the whole forming a corymbose panicle.

paler and pubescent beneath, — becoming a bright crimson in autumn ; petioles %
an inch to an inch in length, often margined, conspicuously villous-ciliate. —
Staminate flowers pedicellate, 2 to 5 or 6 in a loose cluster, on a slender common
peduncle about an inch long. Fertile flowers sessile, mostly 3 in a dense involu-
crate cluster (sometimes 2, or only 1), on a clavate common peduncle, which at first
is about half an inch — finally 1 to 1% inches — in length. Drupe near half an inch
long, bluish-black and succulent when mature ; nut striate-angular.
Hob. Moist woods, and low grounds : frequent. FL May. Fr. Sept.

Obs. The woody fibres of this tree are remarkably curled, or
oblique and interlocked, — so as to render the timber very difficult
to split; on which account it is much used for making naves, or
hubs, for heavy carriage wheels, and also hatters' blocks. A striking
variety — with leaves and fruit more than twice the usual size — was
observed near London Grove Meeting House, during the past sum-
mer (1851), by Mr. JOSHUA HOOPES.

(as if articulated), at the ramifications. Leaves % of an inch to 1% inches long,
3-nerved beneath, smooth, fleshy or subcoriaceous, narrowed at base to a thickish
terete petiole 1 or 2 lines in length. Flowers small, sessile, verticillate, or clustered
on short interrupted spikes,— the staminate flowers mostly 3-parted.
Bab. Branches of trees (mostly Nyssa) : very rare. Fl. May. Fr. Novem.

LORANTHACEAE 255

Obs. This remarkable parasite is becoming so rare amongst us,
that it may be regarded as one (or soon to be one) of the extinct
plants of Chester County. It is, however, rather abundant in New
Jersey,— and frequent, also, in the adjoining States of Delaware
and Maryland. Doctor DARWIN thus refers to the Mistletoe, in his
imaginative Poem: —

" Oh ! stay, bright habitant of air, alight,

Celestial VISCA, from thy angel-flight!—

Scorning the sordid soil, aloft she springs,

Shakes her white plume, and claps her golden wings;

High o'er the fields of boundless ether roves,

And seeks amid the clouds her soaring loves!"

ORDER LXXXV. ULMA^CEAE.

pubescent, purple, ft imam cleft at apex, with the segments so incurved and over-
lapped as to give the margin the appearance of being entire.
Halt. Rich, low grounds; fence-rows, &c. : frequent Fl. April. Fr. June.

256 APETALOUS EXOGENS

Obs. The inner bark of this species is so abundant in mucilage,
that it has been added to the materia medica, in our shops. Being
of smaller size, and the branches rather straggling, it does not
answer for a shade tree so well as the preceding.

SUBORDER II. CELTID'EAE.

Flowers monoicously polygamous ; subsolitary ; fruit a drupe ; albumen scanty ;
mbryo curved.

362. CEI/TIS, Tournef.

on pedicels % an inch to % in length. Drupes about % of an inch in diameter, of
a sweetish taste.
Hob. Great Valley, and slaty hills: rare. FL May. Fr. Sept.

Obs. There is a small form of this, occasion aly found on our
slaty hills, — which seems to be the C. pumila, of PURSH. There is
also one of large size, — with larger and coarser leaves, — which has
been taken for C. crassifolia, of LAMARCK ; but that species does
not appear to be very distinctly denned. Perhaps they may both
be nothing more than varieties of C. occidentalis.

ORDER LXXXVI. SAURURACEAE.

Herbs, aquatic or marsh ; stems jointed; leaves alternate, entire, with sheathing
stipules adnate to the petioles ; flowtrs perfect, destitute of calyx, or other envelopes ;
gtamens 3 to 6, or more; anthers introrse; ovaries 3 to 5, more or less connate;

one of the divisions of the stem; pedicels short, with colored, sheathing, and some-
what spatulate bracts, at base.
Jlab. Margins of pools, and streams: not common. Fl. June. JFV. Sept.

Obs. It appears, by the correspondence of PETER COLLINSON with
JOHN BARTRAM, more than a century since, that this plant was then
known by the name of Aristolochia, — probably from the resemblance
of its leaves to those of the Virginia Snake-root ; and that the
bruised rhizoma was regarded as a salutary application to sore
breasts, — an opinion which prevails among the good ladies, who
deal in simples, at this day.

ORDER LXXXVIL CERATOPHYLLA^CEAE.

associated and closely approximated in the axils of the leaves,— the staminaU being
next the stem, the pistillate, exterior, each with 2 bracts.
Hob. Pools, and sluggish rivulets : frequent. Fl. April. Fr. July,

Obs. This plant presents some varieties, which are doubtless pro-
duced by the circumstances of their locality, — especially one which
is often seen, prostrate and radicating, in muddy places from which
the water has retired ; but I am not sure that we have more than
one species. The plant is thus noticed in DARWIN'S Botanic Gar-
den :-— -

" Thy love, CALLITRICHE, two Yirgjns share,

Smit with thy starry eye and radiant hair ; —

On the green margin sits the youth, and laves

His floating train of tresses in the waves;

Bees his fair features paint the streams that pass,

And bends forever o'er the watery glass."

Of such may be mentioned, the Oroton Tiglium, L. which yields the powerful
Croton Oil, or OH of Tiglium ; the Ricinus oommunis, L. or Castor OH Bean ; the
Jatropha Manihot, L. which affords the Cassava and Tapioca ; the Crozophora tine-
toria, Jnss, yielding Turnsol ; the Siphonia elastica, Pers. affording the true Caaut-

Hob. Woodlands, and moist thickets : not very common. Fl. May. Fr. July.

Obs. This species has been found, growing very luxuriantly in
thickets, along some of the rivulets among our slaty hills, — and in
Londongrove. The Rev. M. A* CURTIS also met with it on the
mountains of North CaroUna ; and Mr. JOHN M'MiNN informs me,
that he finds it in abundance along Spring Creek, near Bellefonte,
in Centre County, Penn'a. It is rather remarkable, that a plant of
its size should have been so long overlooked, by the Botanists.

(or nutshell) containing a 4-lobed seed, without albumen ; cotyledons fleshy and
oily, sinuate-lobed.

An Order consisting chiefly of Walnuts and Hickories,— valuable for their wood,
and some of them for their fruit.

"with a smoothish subcoriaceous epicarp ; nut oval, subcompressed, smoothish, or
somewhat corrugated.
Hob. Yards, &c. Nat. of Persia. Fl. May. Fr. Octo.

Obs. This oriental species is usually called English walnut, — in
consequence of having come to us by way of the mother country.
Such misnomers are not unfrequent among our cultivated plants. —
The young fruit of this is much esteemed, as a material for making
pickles.

%• J. cilierea, L. Leaflets 15 to 17, oblong-lanceolate, rounded

Pistillate flowers 3 to 5 or 7, in a terminal spike, rather distant, on a long common
peduncle. Drupe 2 to 3 inches long, and 1 to near 2 inches in diameter, with u
short tapering protuberance at apex, — often slightly compressed and obscurely
angular, softly hairy and clammy, the epicarp thinnish and somewhat coriaceous.
Hob. Bottom lands ; along streams : frequent. Fl. May. Fr. Sept.

Obs. The young fruit of this species — collected about the last of
June — makes good pickles, — though inferior to the preceding. The
ripe seeds are rather rancid, and scarcely eatable. The bark affords
an extract, which, in the form of pills, is a convenient and popular
cathartic.

WHITE CARTA. Shell-bark, or Shag-bark Hickory.

Stem 60 to 80 feet high,— the outer bark exfoliating in long rigid scales or plates,
•which generally adhere in the middle, while one or both ends are elevated, making
the surface very rugged and shaggy. Leaflets 3 or 4 to 6 or 8 inches long, — the
terminal one usually largest, and the lower pair much smaller. Aments at the
base of the young growth, 2 to 4 inches long, triple or 3-parted on a common
peduncle, pendulous, with a linear-lanceolate bract at the base of each lateral
ament; stamens mostly 4. Pistillate flowers mostly 2 or 3 together, sessile on a
common peduncle. Fruit somewhat umbilicate at both ends, sulcate along the
sutures of the valves ; epicarp thick and subcarnosely coriaceous ; nut about an
inch long, — the shell thin and frangible.
Hob. Low grounds ; along streams : frequent. Fl. May. Fr. Octo.

Obs. The nuts of this tree are well known, and highly esteemed.
There are some varieties, — with the bark less shaggy, the fruit with
a thinner epicarp, the nut with a thicker shell, and a kernel, or
seed, of inferior quality. The whole genus is believed to be peculiar
to this continent, — and is celebrated for affording a superior quality
of fire- wood.

finally hard and woody,— the valves opening more than half way to the base; nut
6-angled near the apex, thick and bony.
Sab. Rich woodlands : common. FL May. Fr. October.

^Obs. There are several varieties of this, — one (var. maxima, Nutt.)
with remarkably large fruit, in Montgomery County, near the Schuyl-
kill, — and possibly in this County, also. 'This species has the wood
white to the centre, — and is regarded as the best of all, for fuel. —
It is replete, in early summer, with a sweet syrup-like sap ; and
when cut, at that season, is much preyed upon by worms. •

3. C., inicrocarpa, Nutt. Leaflets 5 to 7, oblong-lanceolate,
serrate; aments smooth; fruit roundish-ovoid; nut small, some-
what 4-angled, thin-shelle,d.

mon peduncle ; calysp teeth rather conspicuous. Fruit about % of an inch in length ;
fpicarp thin, with the sutures prominent.
Hob. Moist woodlands : frequent. FL May. Fr. October.

Obs. This species seems to be intermediate between C. alba, and
C. glabra ; and, I think, presents several varieties.

peduncle ; calyx-teeth long, linear-lanceolate. Fruit about an inch long ; epicarp
thin, opening but partially. « ..;

Hob. Low, moist woods : frequent, FL May. Fr. Octo.

Obs. The young saplings of this species were formerly much
used for making splint brooms, — on account of the toughness of its
woody fibres ; and the sprouts, or seedling plants, are often em-
ployed, for the same reason, in rural economy, as a kind of rude
ligatures, under the name of Hickory Withes. The mature wood is
preferred, by wheel-wrights, for making the axles of carts and
wagons.

Stem 60 to 80 feet high, with twiggy branches and yellow buds,— the bark at
first close and even, finally more or less fissured. Leaflets 2 to 5 or 6 inches lon^.
slightly pubescent beneath. Aments 1 to 2 inches long, sometimes in pairs.—

JUGLAXDACEAE

Pistillate flowers solitary, or in pairs, pedunculate. Fruit % of an inch long,
thickly sprinkled with yellow resinous particles,— the epicarp thin, with 4 ridged
or prominent sutures at summit, partially opening.
Hob. Low grounds ; along streams : frequent. Fl. May. Fr. Octo.

Obs. This has a general resemblance to the preceding; but the
rule — "by their fruits shall ye know them" — applies well, here.

ORDER XCII. CUPULIF'ERAE.

Trees, or shrubs; leaves alternate, simple, penninerved, with deciduous stipules;
flowers monoicous, — the staminate ones mostly in cylindric (rarely globose) aments,
the pistillate furnished with an involucre which forms a kind of cupule, or covering,
to the (by abortion) 1-celled 1-seeded indehiscent nut ; calyx-tube adherent to the
2- to 7-celled ovary,— the minute calyoc-leeth crowning its summit; embryo without
albumen,— the cotyledons thick and fleshy. A highly important and valuable Order,
—as will appear by the plants here enumerated.

STAM. PL. An\enU several from the same scaly bud, simple, slen-
der, pendulous, — the florets clustered, destitute of bracts. Calyx
6- to 8- (mostly 5-) parted; stamens 6 to 10 or 12. PISTILLATE
FL. in small clusters, sometimes on a long common peduncle. In-
volucre 1 -flowered,. — formed of numerous little imbricated scales
(or bracts] united into a cup, and becoming woody, or bark-like. —
Calyx 6-toothed. Ovary about 3-celled, — each cell with a pair of
collateral suspended ovules ; stigmas as many as the cells. Nut (or
Acorn) ovoid, or oblong, mucronate, surrounded at base (sometimes
nearly included) by the enlarged indurated involucre, or cupule. —
Mostly trees : flowers greenish, — the pistillate ones quite inconspic-
uous; all appearing in May, and the fruit generally mature in
October. In about half the species, the acorns are biennial, — i. e.
2 years in coming to maturity. The Oaks constitute a noble genus, —
being emphatically (as ENDLICHER says of the Order,) "sylvarum
decora " — the pride and ornament of our American forests.

OBTUSE-LOBED QUERCUS. Post Oak. Barrens White-oak.

Stem 20 to 40 or 50 feet high ; branches irregular, spreading, densely pubescent
while young. Leaves 4 to 6 inches long, subcoriaceous. mostly with 3 unequal
angular sinuses,— the upper surface finally smoothish and shining, the under
clothed with a ferruginous or tawny stellate pubescence; petioles about half an
inch in length. Acorn about half an inch long, often depressed or umbilicate at
apex,— the lower half embraced by the scaly hemispherical cupule, which is sessile,
or the fruit often in small clusters on a common peduncle.
2Iab. Dry sterile hills; on Serpentine rock : frequent.

Obs. The wood of this, often rather scrubby-looking species, is
valued for its durability ; and is also esteemed as fuel.

2. Q. alba., L. Leaves oblong-oval, or obovate, regularly pin-
natifid-lobed, — lobes small, oblong, obtuse, mostly entire, the sinuses
narrow; cupule tuberculate ; acorn ovoid-oblong.

WHITE QUERCUS. Common White-Oak.

Stem 60 to 100 feet high, and 2 to 4 or 5 feet in diameter, with a whitish or light
grey bark. Leaves 4 to 6 inches long, usually with 3 to 5 lobes on each side (some-
times cuneate and 3-lobed); petioles % an inch to an inch in length. Acorn of
medium size (near an inch long), seated in a shallowish bowl-shaped pubescent
cupule, — the fruit generally in pairs, sessile on a common peduncle about half an
inch in length.
Hob. Woodlands : every where common.

Obs. This is one of our finest and most valuable forest trees, —
often attaining to an enormous size, and not less entitled than its
English congener, to the epithets employed by COWPER: —

" Lord of the woods, the long-surviving Oak."

The timber is firm and durable, and much used in the various
mechanic arts. The keels of some of our largest national vessels
have been obtained from this Oak. The bark is astringent and
tonic, — while the acorns are sweet and nutritious, affording a favor-
ite food for swine. A variety (or hybrid), with more deeply-lobed
leaves, and considerably larger fruit, has been observed near the
South Western border of our County, by my vigilant friend, Mr.
JOSHUA HOOPES.

f f Chestnut-Oak group ; leaves coarsely and obtusely sinuate-dentate.

3. Q. l>icolor, Willd. Leaves oblong-obovate, unequally den-
tate, densely villous and olive-green beneath ; acorn ovoid-oblong.
TWO-COLORED QUERCUS. Swamp White-Oak.

Stem 40 to 60 or 70 feet high. Leaves 4 to 6 inches long, varying from broad-
ovate to obovate ; petioles about half an inch in length. Fruit in pairs (or often
single), sessile on an axillary common peduncle 1 or 2 to 4 inches long; acorn
rather large, — the cupule dentate on the margin.
Hob. Low grounds ; along streams, Ac. : frequent.

Obs. This is every way inferior in value to the preceding.

4. Q. IHOlltaiia, Willd. Leaves broadly obovate, nearly equally
dentate, pubescent and subglaucous beneath ; cupule subturbinate
at base ; acorn elliptic-oblong, large.

MOUNTAIN QUERCUS. Rock Chestnut-Oak.

Stem 40 to 60 or 70 feet high,— when old, the bark thick and deeply furrowed.
Leaves 4 to 8 inches long, sometimes roundish-obovate, unequal at base, — the
teeth short, broad, and somewhat mucronate, with a callous point; petioles % an
inch to an inch in length. Fruit on short common peduncles ; acorn about an inch
and quarter long, and % of an inch in diameter.
Sab. Hilly, rocky woodlands : frequent.

Obt. The wood of this is considered valuable, — and the bark is
prized by Tanners. The acorns, also, are nutritious, and sought
after by swine.

vtth a coarse tooth for each nerve, and a small callus at apex of each ; petioles I to
near 2 inches in length. Fruit in pairs (1 often abortive) on a common peduncle
about half an inch long; acorn rather thicker than the preceding, but not quite
BO long.
Hob. Great Valley : not very common.

Obs. This species — which is often a fine tree, affording valuable
timber: — presents some varieties; while the whole group have such a
general resemblance, that the elder MICHAUX reduced them all to
modifications of Q. Prinus*

6. O. Castaiica, Willd. Leaves oblong-lanceolate, acuminate,
equally and rather acutely dentate, yellowish above ; acorn roundish-
ovoid, rather small.

CHESTNUT QUERCUS. Chestnut-Oak. Yellow Oak.

Stem 50 to 80 feet high. Leaves 3 to 6 inches long,— the points of the teeth (and
along the whole edge of the leaf) callous ; petioles % an inch to an inch long. Frutt
sessile, or on what seems designed for a short common peduncle* Acorn sweetish
and nutritious.
Hob. Great Valley; near Brooke's Mill : not common.

Obs. This is also variable ; but, generally, the leaves^- both in size
and figure — have a striking resemblance to those of the Chestnut-tree.

APETALOUS EXOGENS

Ob*. This species— which is chiefly valued for fuel— is abundant
in the adjacent districts of Maryland; but has only been found
within the present year (1852), in our County, by the active re-
searches of Mr. JOSHUA HOOPES.

9. Q. ilicifolia, Wangenh. Dwarf; leaves cuneate-obovate,

merous clusters on the branches ; acorn roundish-ovoid.

Q. Banisteri. MX. $ FL Cestr. ed. 2. p. 533.
ILEX-LEAVED QUERCUS. Black Scrub-Oak. Bear-Oak.

Stem, 3 to 6 or 8 feet high, with numerous crooked spreading branches. leaves
2 to 3 or 4 inches long, often 3-lobed at apex, others angularly 5-lobed and some-
what fiddle-shaped ; petioles half an inch to an inch in length. Acorns striped.
Hob. Sterile, slaty hills : frequent.

Obs. This worthless little species is abundant on our Barrens ;
but is rarely seen on good land.

10. Q. tinctoria,, Bartram. Leaves obovate-oblong, sinuate-
lobed, more or less rusty -puberulent beneath ; cupule scaly, thick ;
acorn ovoid, rather small.

DYER'S QUERCUS. Black-Oak. Quercitron.

Stem 60 to 80 or 90 feet high, and 2 to 4 feet in diameter, with a thickish fur-
rowed dark-colored outer hark, and a spongy yellow inner bark. Leaves GOT 8
inches long, obovate in their outline, more or less deeply sinuate-lobed (usually 3
principal lobes on each side),— the under surface loosely clothed with little fascicles
of short hairs, which give it aroughish powdery appearance; petioles 1 to 2 inches
in length.
Hob. Rich upland woodjs : common.

Obs. The wood of this fine tree is not so valuable as that of some
others; but the inner bark is a considerable article of commerce,
under the name of Quercitron. It is employed in dyeing yellow ;
and has nearly superseded the use of Weld (Reseda luteola, L.), in
the manufactories of Europe, in calico printing.

11. Q. COCCiliea, Wangenh. Leaves oval in outline, deeply
sinuate-pinnatifid, with broad and open sinuses, smooth and shining
green on both sides; cupule conspicuously scaly; acorn roundish-
ovoid, depressed at apex.

CRIMSON QUERCUS. Scarlet-Oak.

Stem 50 to 80 feet high. Leaves 4 to 6 or 8 inches long, with 3 or 4 principal
narrowish divergent lobes on each side, the sinuses deep, rounded and wider at
bottom, — becoming a showy crimson in autumn : petioles 2 to 4 inches in length.
Hob. Hilly woodlands : frequent.

Obs. The bark of this tree is much sought after by our Tanners,
who (not being acquainted with the Q. falcata) erroneously call it
" Spanish Oak"; and give it the preference over all the other Oaks,
that are common here, for their business. The crimson leaves of
this species, where it abounds, impart a gorgeous and magnificent
appearance to our forests, in autumn; and it is really marvellous,
that a tree so handsome at all seasons, should be so rarely seen in
the lawns and pleasure grounds of persons of any pretensions to
taste.

CUPULIFERAB 269

12. Q. falcsfcta, MX. Leaves lobed toward the apex, the lobes
elongated, and the lateral ones more or less falcate, — the under
surface clothed with a short greyish-tawny pubescence; cupule
shallow ; acorn roundish-ovoid.

FALCATE QUERCUS. Spanish-Oak.

Stem 50 to 80 feet high, — the young branches often tawny-pubescent. Leaves 4
to 8 or 9 inches long, obtuse at base, with 2 or 3 distant and mostly falcate lobes
on each side, — those on small trees, or young branches, often dilated and 3-lobed
at apex ; petioles about an inch in length, densely pubescent when the young
branches are. Cupule on a short peduncle.
Hob. Woods, on the North Valley hill : very rare.

Obs. Although abundant in Delaware, and Maryland, this species
was not detected, in our County, until the present season (1852), —
when specimens were brought to me, from the above named locality,
by my friend JOSHUA HOOPES — whose vigilant and quick-discerning
eyes, few such natural objects, within the circuit of Ms walks, are
permitted to escape. The bark of this, which is the true Spanish
Oak, is believed to be the best of the genus, for the purpose of tan-
ning hides.

* * Cupule flat at base, sJiattow and saucer-shaped.

13. <J. rftbra, L. Leaves pale beneath, sinuate-lobed, the sin-
uses rather shallow ; acorn oblong-ovoid, rather large.

RED QUERCUS. Red Oak.

Stem, 60 to 90 feet high. Leaves 5 to 8 or 9 inches long, and 3 to 6 inches wide,
oblong or obovate, with short incised-dentate lobes (usually 3 principal lobes, and
2 or 3 smaller ones, on each side) ; petioles 1 to 2 inches in length. Cupule with
the scales so compact as to present a smoothish, or nearly even, outer surface ;
acorn a little turgid, or plump, about an inch long.
Hob. Hilly woodlands : frequent.

Obs. Justice to myself, and to the truths of Natural History — as
well as to Mr. EMERSON, author of the admirable Report on the
Forest trees and Shrubs of Massachusetts — requires that I should
here rectify a misapprehension under which I labored, when com-
piling the little work entitled Agricultural Botany. I had always
understood (of course, from others — having no personal knowledge
of the subject,) that the bark of this species was in high repute with
the Tanners, — and so stated : But, on a more careful and particular
inquiry of intelligent practical men, in that business, I learn that
it is regarded as being much inferior in value to the bark of Q.
cocdnea, — and am now satisfied that Mr. EMERSON is substantially
correct in the statement, that it is "almost worthless for the use
of the Tanner." The timber of this tree is also of inferior value.

14. Q. paltistris, Du Roi. Leaves smooth and green on both
sides, deeply sinuate-pinnatifid, with broad rounded sinuses and
divaricate lobes ; acorn subglobose, small.
MARSH QUERCUS. Pin-Oak. Water-Oak.

Stem 40 to 60 or 70 feet high ; branches numerous, rather slender, horizontal or
drooping, often nearly covered with diseased knobs. Leaves 4 to 6 inches long, usual-
ly with 3 narrow divaricate lobes on each side; petioles 1 to 2 inches in length.—

270 APETALOUS EXOGEN8

Cujnfa nearly even on the outer surface, often abruptly tapering from the fiat

base ; acorn scarcely half an inch long.

Hah. Wet, low grounds ; along streams : frequent.

Obs. The wood of this species is very firm, — and is much em-
ployed by wheelwrights, and other mechanics. It would seem that
this, and the Q. falcata, are severally pretty much confined to
opposite sides of Mason and Dixon's line; the Q. palustris being
chiefly northern, and the Q. falcata southern.

clusters of 3 or 4, subsessile, enlarging, finally globose, about 2 inches in diameter,
thickly covered or armed all over with sharp compound or coalesced prickles
(modified &rac&), and densely villous within. Nuts 3 (by abortion often 2, or 1),
reddish-brown, smooth below, the upper half covered with a greyish-tawny pubes-
cence ; the middle nut flatted on both sides, the lateral ones plano-convex, — and
when the lateral ones are both abortive, the central one becomes roundish-ovoid.
Hob. Woodlands ; slaty hills, abundant. FL June. Fr. Octo.

Obs. The American Chestnut-tree scarcely differs from the Eu-
ropean, except in the size and flavor of the fruit. Our native nuts
are smaller, and the seeds much sweeter, than those of the European
variety. The wood of this tree is light, but very durable, — not
esteemed for fuel, but highly valued for making fences.

2« C» pillllila, MX. Dwarf; leaves obovate-oblong, acute, serrate

or denticulate, whitish-tomentose beneath j nut solitary, ovoid,

small.

DWARF CASTANEA. Chinquapin.

Stem 6 to 10 feet high (much larger under culture). Leaves 2 to 6 inches long ;
petioles about half an inch in length. Aments of staminate flowers 1 or 2 to 4 inchea
long, slender and numerous. Involucres of the pistillate flowers in spikes, or
clustered on short tomentose axillary common peduncles, finally globose, an inch
or inch and half in diameter, armed all over with the prickly bract*. Nut (by

abortion?) constantly solitary, small, ovoid, acute, dark brown, pubescent at

summit.

Ifab. Thin soils; near the Maryland line. Fl. June. Fr. Octo.

Obs. This shrub is rare, north of Maryland, — in some portions of
which State it is very abundant. The seeds are sweet, and pleasant,
— but are scarcely half the size of our chestnuts ; while both (and
especially the chinquapins) are very subject to be preyed upon by
worms.

culate involucre, which is formed of numerous coalesced subulate
flexible bracts. Calyx urceolate, — the border elongated, and cleft
into 4 or 5 subulate segments. Ovary 3-celled, with 2 ovule* in
each cell [A. Gray. "Ovula in loculis solitaria," Endl."]; styles 3,
filiform ; stigmas lateral. Nuts ovoid-triquetrous, usually 2 in the
coriaceous flexibly-muricate 4-valved involucre. Cotyledons thick,
plicately folded. Trees, with a thin smooth cinereous bark, hori-
zontal branches, long terete acuminate buds, and greenish-yellow

Leaves oblong-ovate, acuminate, more
or less dentate, ciliate ; the flexible-armature, or bracts, of the in-
volucre spreading, or recurved.

% to % an inch in length ; Stipules long, linear, membranaceous, tawny, caducous.
Aments of staminate flowers loosely subglobose, numerous, on slender peduncles 1
to 1% inches long. Involucres of pistillate flowers fewer, on rigid axillary peduncles
about half an inch in length.
Hob. Low moist woodlands : frequent. FL May. Fr. Sept.

Obs. The wood of this tree, from its density and uniform texture,
is much valued for many purposes ; and the oily Mast, or seeds,
afford a nutritious food for swine.

The Beech — although a symmetrical and handsome tree — has been
unaccountably neglected, in this country, as an ornamental shade-
tree: and yet it would seem, from VIRGIL'S Pastorals, that in the
land of sweet do-nothing ("dolce far niente"), the Italian Peasant,
of ancient times, found an enviable enjoyment under its spreading
branches —

"patulae recubant sub tegmine FAGI."

Our Aborigines, however, think they have improved upon the
luxurious indulgence of the Italians,— judging by the following re-
mark of an Indian Chief to Col. BUTLER — as reported and rendered
by ST. JoHNDECaivECOEUR:— "Ah! mon frere, * * * tune con-

subcompressed at apex, solitary or separately inclosed in the en-
larged leathery foliaceous bilabiate lacerate-dentate involucre. —
Shrubs: the staminate aments preceding the leaves, yellowish-green
when in flower.

Stem 6 to 10 feet high, branching from the base. Leaves 3 to 4 or 5 inches long,
often obovate-cordate, doubly serrate ; petioles*% to % of an inch in length. Pistil-
late flowers few, in squamose clusters,— the scales (or bracts) enlarging, uniting
and forming the involucres. Stigmas purple. Nuts rather large.
Hob. Yards, &c. Nat, of Asia Minor. FL March. Fr. Sept.

Obs. The Filbert, or Hazel-nut, of the old world, is now becoming
known among us, — and not unfrequently cultivated. "The bushes
were originally imported into Italy from Pontus, and [the fruit]
known among the Romans by the appellation of Nux pontica, —
which, in the progress of time, was changed into that of Nux Avel-
lana ; from the place \_Avella, near Naples] where they had been
most successfully propagated." The young forked twigs of this
shrub constitute the celebrated divining-rod (Virgula divinitoria),
with which certain impostors beyond the Atlantic pretend to dis-
cover the localities of precious metals, and subterranean fountains.
The imposture, and the credulity on which it operated, have both
reached our shores; but the Filbert not being indigenous here, a
capital substitute, or phytognostic equivalent, was discovered in the
Witch Hazel (Hamamelis) \ The twigs of Peach trees, also, have been
found to answer the purpose nearly as well as Witch Hazel ; and
thus the occult sciences df Ore-finding, and Water-smelling, have
been enabled, in some degree — even in this "progressive" age — to
keep pace with the sublime mysteries of Clairvoyance, and Spiritual
Rappings; as well as with the lucrative manufacture of Panaceas,
and Indian Specifics! It is, indeed, both humiliating and discourag-
ing, to contemplate the facility with which a large portion of man-
kind can be made the dupes of such miserable trumpery.

2. C. Americana, Marshall. Leaves obovate-cordate, acumin-
ate; stipules ovate; involucre about twice as long as the fruit,
Yentricose at base, the border dilated and compressed.
AMERICAN CORYLUS. Wild Hazel-nut.

of an inch to an inch in length. Pistillate, flowers several (often 6 or 8), in pedun-
culate squamose clusters,— the scales enlarging , uniting and forming the glandular-
hispid involucres. Nuts % an inch in length, rather wider than long.
ffab. Borders of thickets: frequent. FL March. Fr. Sept.

Obs. This shrub is well known, for its fruit, — which, however, ia
inferior to that of the preceding species.

3. C. rostr ata, Ait. Leaves oblong-ovate, acuminate ; involucre

contracted into a tubular beak, and extended much beyond the

fruit.

BEAKED CORYLUS. Dwarf Filbert.

Stem 2 to 4 or 5 feet high, slender, branching, smoothish. Leaves 2 to 3 inches
long, truncate or slightly cordate at base, doubly serrate; petioles % to ^ an inch
in length. Pistillate flowers few (about 3), in pedunculate clusters, sometimes
solitary. Involucres hirsute, about 3 times as long as the fruit,— the base ovoid,
half an inch in diameter — the beak about an inch long, nearly cylindrical, sulcate-
striate, 2-parted half its length.
Hob. Along Brandy wine, near Coatesville : rare. FL April. Fr. Octo.

Obs. This curious little species was detected in the above locality,
in 1841, by Mr. JOHN M'MiNN, a zealous Naturalist, — then of
Chester, now of Centre County, Penn. % ,

376. CARPrWUS, L.

[The ancient Classical name.]

STAM. FL. Aments lateral, with simple ovate scale-like bracts, — the
florets destitute of a proper calyx. Stamens about 12, at the base
of the bract ; anthers hairy at apex. PISTILLATE FL. in pairs, with
small deciduous bracts, and enlarging foliaceous halved or 1-sided
involucres, arranged in terminal loose ament-like racemes. Calyx
urceolate, — the border cup-like, denticulate. Ovary 2-celled; stig-
mas 2, filiform. Nuts in pairs, small, ovoid, subcompressed, striate-

bract); anthers oblong, 1-celled, subsessile. PISTILLATE AMENTS
with the bracts 3-lobed, imbricated. Calyx none. Ovaries 3 under
each bract ; stigmas 2, filiform. Fruit a lenticular winged nut, or
samara, by abortion 1-celled, 1-seeded; feed pendulous. Mostly
trees, with a smooth reddish-brown (sometimes white) bark which

their length. Nuts compressed, ovate, with a ciliate margin which is widest
toward the base.
Hob. Low grounds; along streams: not common. Fl. April. Fr. Aug.

Obs. The timber of the Birches is not particularly valuable, —
though sometimes converted into lumber. The virgate branches were
famous instruments in the hands of Pedagogues, of the olden time,
in promoting good order, and a close attention to study, among the
rising generation; to which fact the Poet PHILIPS refers, when he
sings of

" afflictive Birch,

"Curs'd by unlettered, idle youth."

But the " march of mind," in our age of progress, has rendered such
auxiliaries nearly "an obsolete idea"! The flexible twigs of this
species — instead of being used to regulate and stimulate unruly
and idle boys — are now chiefly employed in the manufacture of
coarse brooms, for sweeping streets, and stable-yards, in our cities.

ciliate, and wider toward the summit,— but narrower throughout, and smoother,
than in the preceding species.
Hob. Along rivulets, on the slaty hills : rare. Fl April. Fr. Aug.

Obs. The wood of this is said to be rose-colored and fine-grained, —
valuable for cabinet-work. The bark, and young twigs, are pleas-
antly aromatic, — and sometimes employed in domestic brewings,
and diet-drinks.

dular-serrate.*

* In revising our Native Willows, I have been under great obligations to JOHN
CAREY, Esq. of New York,— the acute and able Botanist who elaborated that difficult
family for Prof. A. GRAY'S Manual; — and who was so kind as to examine my
Chester County specimens, and to determine them in accordance with the said
Manual.

Obs. The student who undertakes to master this formidable
genus, will find it necessary to note various minute features which
would escape a common observer; and he should, moreover, at-
tend to the characters as exhibited, at different stages of the plants,
both by the fructification, and the foliage. Great care is requisite,
also, to prevent confusion in the Herbarium, — which is apt to result
from the collections being made at different times, and then mixing
together aments, and leaves, belonging to different species. My
amiable and lamented friend, the late Rev. Mr. SCHWEINITZ, used
jocularly to say, that if a Botanist were to commit a very grave
penitentiary offence, his punishment should be, to prepare a com-
plete monograph of the Solidagines I I incline to the opinion, how-
ever, that it would be a much severer sentence, to require a perfect
monograph of the Salices.

Ilab. About hoilses ; low grounds. Nat. of Europe. FL April. Fr.

Obs. The white 'willow, if I mistake not, is the one which is pre-
ferred, and cultivated, by the manufacturers of Gun-powder, for
the purpose of making charcoal. It was introduced as a shade-tree,
about our old settlements; but is now generally superseded by the
Weeping Willow. It is, however, partially naturalized in some
localities. The S. vitellina, L. with more spreading orange-yellow
branches, and rather shorter and broader leaves (which Mr. CAREY
reduces to a var. of this) — is also occasionally seen, as a shade-
tree, and partially naturalized. I think we have none but the pis-
tillate plants, of both varieties. The twigs of the var. vitellina, or
golden Osier, are much used, in Europe, for making baskets. In
WATSON'S Annals of Philadelphia, we are told that the Yellow Wil-
low, in this State, came originally from some wicker-work found
sprouting, in Dock Creek. It was seen by Dr. FRANKLIN, who
took it out and gave the cuttings to CHARLES NORRIS ; who reared
them on the grounds now the site of the Custom House, or late
Bank of the U. States.

f f Ovary pedicellate.

8. S. frdgilis, var. Russelliana, Carey, in Gr. Man. Leaves lanceo-
late, acuminate, serrate-dentate with the teeth incurved, subglaucous
beneath, and slightly silky while young ; stipules semi-cordate ;
styles conspicuous.

Obs. This species is abundant on the Brandywine, about Wistar's
Bridge ; and has been advantageously propagated, inr that vicinity,
in localities where few other trees would grow. I have seen none
but pistillate plants.

5). S. niarra, Marshall. Leaves narrow-lanceolate, 'tapering and
acute at each end, smooth and green on both sides, with the petiole

Leaves 2 to 3 inches long ; petioles 1 to 2 or 3 lines in length, often very pubescent,
sometimes smoothish. Staminate aments 1% to 2 inches long, rather slender,
tomentose ; stamens usually about 5. Pistillate aments about an inch long.

Var. falcata, Carey, in Gr. Man. Leaves 3 to 6 inches long, more
or less falcate, tapering gradually to the apex, and often obtuse at
base; petiole and midrib smooth ; stajtwZesreniform-eordate, reflexed,
large and persistent on young branches.
S. Purshiana. Spreng. $ Fl. Cestr. ed. 2. p. 560.
Sab. Low grounds; along streams : frequent. FL May. Fr. June.

Obs. Since the 2nd Edition was published, I have seen handsome
trees, of the var. falcata, in the adjoining County of New Castle, 25
to 30 feet in height ; and have received beautiful specimens from
the banks of the streams among the Allegheny Mountains, from my
industrious and observing friend, Mr. JOHN M'MiNN.

1O. S. liicicla, Muhl. Leaves ovate-oblong, oval, or lanceolate,
often coriaceous, conspicuously acuminate, glandular-serrate, smooth

inch in length, glandular near the leaf. Staminate aments 1 to 1% inches long.—
Pistillate aments 1 to 2 inches long. Coma of the seeds long and copious.
Ifab. Banks of the Brandy wine, near Downingtown : rare. Fl. May. Fr.

Obs. I have received, since the last Edition, specimens from the
mountains, by Mr. JOHN M'MiNN, of Clinton County, with leaves
quite as large as those figured by MICHAUX, thick and coriaceous,
with a remarkable acumination.

XL S. BABYLONICA, L. Young branches very slender, flaccid, and
pendulous; leaves linear-lanceolate, acuminate, usually sharply
serrate-dentate, smooth, glaucous beneath; stipules ovate, acumi-
nate, glandular-dentate, revolute ; aments recurved.
BABYLONIAN SALIX. Weeping, or Drooping Willow.

Stem 30 to 50 feet high, with a wide-spreading top ; young branches greenish,
numerous, long and perpendicularly pendent. Leaves 2 to 4 or 5 inches long;
petioles 1 or 2 lines in length. Pistillate aments about an inch long, mostly curved
or turned upward on the pendulous branches.
Hob. About houses. Nat. of the East. FL April. Fr.

Obs. This picturesque and elegant species is deservedly admired,
and much cultivated, as an ornamental shade-tree. TOURNEFORT
thus defines it: — "S. orientalis, flagellis deorsum pulchre penden-
tibus." LINNAEUS, adopting the idea of RAUWOLF, gave it the
specific name which it now bears, — in allusion to the 137th Psalm: —
"By the rivers of Babylon, there we sat down, yea, we wept, when
we remembered Zion. We hanged our harps upon the Willows in
the midst thereof." According to Mr. WATSON, the Annalist of
Philadelphia, the first Weeping Willows were introduced by Gov.
JOHN PENN, for his Garden, in South third street. None but the

I 8ALICACKAE 281

pistillate plant has yet been seen, — either here, or in Europe. A
singular variety (annularis, or Ring-leaved Willow), with small
curled leaves, has been introduced within a few years. Several of
the Willows afford good material for Basket-work; but the species
most highly prized, for its pliable twigs, is the Common Osier (Salix
vimindlis, L.), — which is said to be well worthy of culture, as a
profitable business. I think I have not yet seen that species in our
County ; though its introduction would probably pay, at this time,
better than Morus multicaulis.

382. POP'UL,US, Tournef.

[Latin, Populus, the people; being used to shade the People's, or public, walks.]
Aments with the bracts laciniately incised at apex. Calyx a sub-
turbinate cup-shaped disk, — the border obliquely lengthened in,
front, entire, surrounding the stamens, or pistil. Stamens 8 to 12,
or more; filaments distinct. Stigmas large, 2- or 3-lobed. Trees:
branches more or less angular, often stoutish ; bud-scales numerous,
imbricated, coated with resinous varnish ; leaves often broad, sub-
cordate or ovate, on long laterally compressed petioles ; aments pre-
ceding the leaves, — -the bracts and calyx similar in both kinds.

1. P. tremulQides, MX. Leaves cordate-orbicular, abruptly
acuminate, denticulate ; bracts deeply 3- or 4-lobed ; lobes linear.
TREMULA-LIKE POPULUS. American Aspen.

Stem 30 to 60 feet high, (tall and slender, when crowded,— shorter and round-
topped, when single), with a smoothish cinereous bark. Leaves about 2 inches in
length (on young plants, much larger), and rather wider than long ; petioles 2 to 3
inches long, slender, laterally much compressed (or vertically dilated) near the
leaf, — which compression subjects the leaf to a tremulous motion from the slightest
breeze. Pistillate aments 3 to 4 or 5 inches in length. Bracts deeply incised, and
fringed with long grey hairs. Stigmas dark purple.
Bab. Low grounds ; Brandy wine : not common. Fl. April. Fr. May.

Obs. This is sometimes cultivated, as an ornamental shade-tree;
and its bark is a popular tonic. The Quaking Aspen, of Europe (P.
tremula, X.)-^which ours resembles — is scarcely known, here.

2. P. grandidentata, MX. Leaves roundish-ovate, acute,
coarsely sinuate-dentate; bracts dentate, or 5- or 6-lobed; lobes
small, unequal.

LARGE-TOOTHED POPULUS.

Stem 30 to 50 feet high,— when growing singly, tUe top rather large and round-
ish ; bark smooth, greenish-gray. Leaves 3 to 4 or 5 inches long, and about as
wide as long ; petioles 2 to 3 inches in length. Pistillate aments 2 to 3 inches long.
Bracts slightly fringed, or somewhat coarsely dentate.
Sab. Moist woodlands: becoming rare. FL April. Fr. May.

3. P. lieteropliyl'la, L. Leaves roundish-oblong, or deltoid-
ovate, obtuse, uncinately serrate, often auriculately subcordate at
base with the sinus small, densely and softly tomentose while young.
VARIOUS-LEAVED POPULUS.

Stem 30 to 50 feet high, with a greyish-brown bark. Leaves 3 to 6 or 8 inches
long, and 2 to 6 inches wide; petioles 2 to 4 or 5 inches in length,— at first densely
clothed, like the leaves, with a soft cinereous (or often slightly tawny) tomentum.

4. P. GRAECA, Ait. Leaves cordate-ovate, acuminate, uncinately
serrate.

GREEK POPULUS. Athenian Poplar.

Stem 30 to 50 feet high, with irregular and rather spreading branches. Leaves
4 to 6 or 8 inches in length, and about as wide as long; petioles 1% to 3 inches
long. Pistillate aments 3 to 6 inches in length.
Hob. Streets, and yards. Fl. April. Fr. May.

Obs. This species was introduced, here, as a shade tree, early in
the present century; but it was not generally adopted,— and is now
nearly superseded by more eligible ones. We have only the pistil-
late plant ; and the cottony coma, from the bursting capsules, is so
abundant as to render the tree objectionable, in the immediate
vicinity of dwellings. It is stated in SELBT'S History of British
Forest Trees (1842), that the North American Continent is probably
the "real native country" of this Poplar, If so, AITON'S specific
name (Graeca,) was an unfortunate misnomer: a mistake, however,
not uncommon in vulgar names.

5. P. DILATXTA, Ait. Leaves much dilated, nearly deltoid, acumi-
nate, serrate, smooth on both sides.

DILATED POPULUS. Lombardy Poplar. Italian Poplar.

Stem 60 to 80 feet high ; branches numerous, nearly erect, forming a close
conical-oblong symmetrical top. Leaves 2 to 3 inches in length, and rather wider
than long; petioles about 2 inches in length. Staminate aments 2 to 3 inches long,
the bracts finely fringed.
Hob. Streets, and avenues, FL April. Fr.

Obs. This was a favorite ornamental tree, for a number of years ;
but is now (1852) nearly obsolete. Mr. WATSON, in his Annals of
Philadelphia, says it was introduced from England, in 1784, by
WILLIAM HAMILTON, Esqr., of the "Woodlands," near that City. —
The Botanical Editor of REES'S Cyclopaedia, however, thinks they
have only the pistillate plant in England, — whereas it was the stam-
inate plant that was introduced by Mr. HAMILTON ; and he may
have procured it from the Continent. SELBY, in his British Forest
Trees, says this Poplar was probably brought into Italy, from Per-
sia. It is called P. fastigiata, by DESFONTAINES ; and SELBY uses
the term fastigiate in its original sense of taper-pointed, conical or
pyramidal, — instead of level- or flat-topped, which is the meaning
attached to it by most modern Botanists.

6. P. ALBA, L. Leaves roundish-cordate, or often 3-lobed, coarsely
dentate, smooth and green above, mostly white and densely tomen-
tose beneath.

WHITE POPULUS. Silver Poplar. Abele-tree.

Stem 30 to 60 feet high, with spreading branches and a smooth greyish-white
bark. Leaves 2 to 3 inches long,— -when old, sometimes glabrous on both sides ;
petioles 1 to 2 inches in length. Aments 1 to 2 inches long,— the bracts finely
laciniate and ciliate with white hairs.
Bab. Streets, and yards. Nat. of Europe. Fl. April. Fr.

Obs. This is becoming somewhat frequent, as a cultivated shade
tree, — though its tendency to send up suckers, all around it, renders

SALICACEAE 288

it rather troublesome, It is this species to which that delightful
Poet of Nature, COWPER, refers, — where he mentions the
" Poplar, that with silver lines his leaf."

ORDER XCVI. PLATANACEAE.

Trees, with a watery juice; leaves alternate, petiolate, palmately nerved and lobed,
with sheathing intrapetiolar stipules, — the petioles tumid and hollow at base, con-
oealing the young buds; flowers monoicous, minute, densely crowded in separate
naked globose long-peduncled pendulous aments; calyx none: STAMINATE FLOWERS
in small deciduous heads ; stamens numerous, mixed with subclavate scales (of
ataminodia ?) : PISTILLATE FLOWERS in larger persistent heads ; ovaries numerous,
filiform-clavate, mixed with spatulate scales (abortive ovaries?); styles rather
lateral, simple, subulate ; fruit a 1-celled 1-seeded clavate coriaceous little nut^
which is invested at base, with tawny pappus-like hairs ; seed pendulous, with
fleshy albumen.

383. PI-AT'AWUS, L.

[Gr. Platys, broad; in allusion to the ample shade of its foliage.]
$g^ The Order consisting of a single Genus, the character of both
is necessarily the same. Large frees, with cinereous exfoliating
bark. .

1. P. occidental!*, L. Leaves roundish-pentagonal, sinuate-
lobed and dentate, clothed with a branching deciduous pubescence.
WESTERN PLATANUS. Button-wood. Plane-tree.

(Stem 60 to 100 feet high, and 3 to 5 feet, or more, in diameter, — with large spread-
ing branches, and a smoothish cinereous bark, which exfoliates in broad thinnish
plates. Leaves 4 to 6 or 8 inches in length, and rather wider than long, — the base
at first truncate, finally subcordate ; peiioUs 1 to 3 intb.es in length ; stipules some-
what salverform, sheathing the young branches immediately above the petioles,-—
the border foliaceous, coarsely and unequally toothed. Staminate heads small, on
peduncles 1 to 2 inches long. Pistillate heads about an inch in diameter, on
peduncles 3 to 5 inches long. Nuts about % of an inch in length, slender, sub-
terete, clavate. mucronate, the base acute.
Hob. Banks of streams, and roadsides : frequent. Fl. April. Fr. October.

Obs. This stately tree — originating from a very small seed — often
attains to a larger size than any other, east of the Rocky Mountains.
For a number years past, it has been affected with some disease,
which has materially impaired its luxuriant growth, — the nature,
or cause of which affection, seems not to be well ascertained.

ORDER XCVII. URTICA^CEAE.

Trees and shrubs with a milky juice,— or herbs with a watery juice ; leaves alternate,
or opposite, often stipulate; flowers monoicous, dioicous, or polygamous, furnished
with a regular calyx, — sometimes arranged in ament-like spikes, or fleshy heads;
gfamens as many as the calyx-lobes, and opposite them ; ovary free from the calyx,
mostly 1-celled, with a solitary ovule ; fruit an akene, or utricle, — often inclosed in
the fleshy calyx, and clustered so as to form a compound berry, — or all contained
in the cavity of the general receptacle ; embryo curved, or straight, — with, or with-
out albumen.

This is a comprehensive and important, though rather heterogeneous, order, —
comprising 4 subdivisions, which ENDUCHER has erected into as many distinct

284 APETALOUS EXOGENS

Orders, designated as the Bread-fruit, Mulberry, Hemp, and Nettle families. It
certainly contains plants of remarkably dissimilar aspect and properties ; such as
the Nettle and the Mulberry — the bitter Hop and the luscious Fig — the nutritious
Bread-fruit (Artocarpus ina'sa, i.) and the reputed deadly Upas (Antiaris toxicaria,
Leschtn). The celebrated Cow-tree, or Palo de Vaca (Brosimum Galactodendron,
Don), of South America — " which yields a copious supply of rich and wholesome
milk" — belongs to this Order; as also does the yellow-dye wood, called Fustic
(Madura tinctoria, Don), the wide-spreading Banyan tree (Ficus religiosa, Z.) of
India, &c.

SUBORDER I. MORE^AE. *

Trees, or shrubs, with a milky juice; leaves alternate, with deciduous stipules;
staminate and pistillate flowers sometimes intermixed, but usually in separate
epikes, or heads, — and occasionally (as in the Fig) included in the hollow recep-
tacle; the calyx, or receptacle, of the pistillate flowers, becoming succulent in fruit;
Stigmas 2 ; embryo curved, in copious albumen.

384. MACL.ITRA, Nuttall.

[Dedicated to William Maclure, — a munificent Patron of Natural Science.]
Flowers dioicous : STAM. FL. racemose. Calyx 4-parted. PISTIL-
LATE FL. densely crowded, and coalesced, on a globose receptacle.
Sepals 4, in opposite pairs, oblong, somewhat cucullate and fleshy.
Ovary 1-celled, sessile; style terminal, bifid, — one branch large,
much exserted, stigmatic on the inner side, — the other small, or
abortive. Akenes 1 -seeded, embraced by the sepals, and all coa-
lesced into a large compound globose lactescent yellowish-green
berry, with a glabrous, but uneven, irregularly tessellated surface.
Small trees, — the branches armed with very sharp slender spines.

1. M. AURANTIACA, Nutt. Leaves lance-ovate, acuminate, entire,
smooth and shining above, puberulent beneath ; berry subsessile,
axillary, solitary.
ORANGE-LIKE MACLURA. Osage Orange. Bow-wood.

Stem 20 to 30 feet high, with a much-branched spreading or bushy top, — the
branches virgate, but often inclined to droop or curve downward, armed with small
and very sharp spines, Leaves 4 to 6 inches long, subcoriaceous, mucronate;
petioles 1 to 2 inches in length ; stipules oblong, somewhat cucullate, caducous.—
Principal style-branch near an inch long, villous, purplish. Fruit coalesced in a
solid globose head which is 2 to 3 inches in diameter.
Hob. Yards; hedges, <fcc. Nat. of Arkansas. FL May. Fr. Oct.

Obs. The roots of this are of a bright orange color, — and so abun-
dant, and extensive, as to be troublesome, in gardens. The wood
shows an affinity with that of the Mulberry, — and therefore is
probably durable. It is said to have been highly valued for making
Bows, by the aboriginal hunters and warriors. I have observed
that Silk- worms feed greedily on its leaves ; and the young plants,
properly managed, promise to make a very neat and effective hedge, —
though I apprehend the roots would exhaust the soil to an injurious
extent on each side, in cultivated grounds.

*We have no plant belonging to the Suborder ARTOCARPEAE, or Bread-fruit
division, growing in this County. The nearest approach to the structure and
appearance of the Bread-fruit, is in the fruit of the Madura, or Osage Orange,—
which has been introduced from the South West.

t URTICAOEAB 285

385. ItlCTRVS, Tourmf.
[From Morea, — the Greek name of the Mulberry.]

Flowers mostly monoicous: calyx 4-parted. STAM. FL. in loose
ament-like spikes, — the spikes sometimes androgynous. PISTILLATE
FL. in short dense spikes. Ovary 2-celled, — one of the cells smaller,
and disappearing ; styles 2, filiform, stigmatic on the inner side. —
Akene compressed, ovate, covered by the persistent succulent calyx,
— the whole spike thus becoming a compound terete oblong berry. —
Leaves often lobed ; flowers greenish.

1. M. rrtbra, L. Leaves cordate-ovate, acuminate, sometimes 2-
or 3-lobed, scabrous above, pubescent beneath ; fruit dark purple.
RED MORUS. Red Mulberry.

Stem usually 15 to 25 feet high, with numerous spreading branches. Leaves 4
to 6 or 8 inches long, dentate-serrate, often lobed on young plants ; petioles 1 to 3
inches in length. Flowers numerous, in axillary pedunculate ament-like spikes,
— often androgynous, sometimes dioicous. Staminate spikes 1 to near 2 inches
long. Pistillate spikes about an inch long, — becoming juicy, sweet, and pleasantly
esculent when mature.
Hob, Rich woodlands ; fence-rows, &c. : frequent. FL May. Fr. July.

Obs. The wood of this small tree is very durable ; and the fruit
preferred to that of any other species, known here.

2. M. dlba, L. Leaves obliquely cordate-ovate, acute, somewhat
lobed, smoothish and shining ; fruit usually yellowish- white.
WHITE MORUS. White Mulberry.

Stem 10 to 20 or 25 feet high, branched, and spreading at top. Leaves 2 to 4
inches long (in young plants, much larger), unequally crenate-serrate, yellowish-
green; petioles % an inch to an inch in length. Pistillate spikes shorter and
smaller than in the preceding. Fruit straw-color, when mature, — rarely dark
purple or nearly black.
Sab. Fence-rows, &c. Nat. of Asia. FL May. Fr. July.

Obs. The White Mulberry was introduced into this County, nearly
a century since, with a view to the Silk-culture. The project, how-
ever, was soon abandoned ; for, in that early stage of the Colony —
with all manufacturing pursuits discountenanced by the Mother
Country — the sparsely settled Agriculturists soon found it more
profitable to attend to mammiferous animals, rather than Insects.—
But the tree became partially naturalized, — and is yet to be seen
about a number of old settlements. About fifteen years ago, a
variety of this species — of smaller stature and much larger leaves
(well-remembered by the name of Morus multicaulis] — was intro-
duced, as being still better adapted to the feeding of Silk- worms ;
and soon thereafter, a scene of speculation and infatuation was
exhibited, thoughout the U. States, which — like some of its Euro-
pean prototypes — bade defiance to all the suggestions of reason and
common sense. There was a sort of wild enthusiasm, or furor, so
universal and vehement, that it became positively ludicrous; and
was scarcely exceeded, in absurdity, by the nearly contemporaneous
epidemic, which led our excitable people, in a fit of political delirium, to
wage a destructive war upon their own currency. During the preva-
lence of the Moro-mania, every body was eagerly engaged in prop-

286 APETALOUS EXOGENS

agating myriads of trees to sell — without stopping to inquire whew
they could be sold, or who would be likely to buy ! Of course, it
was not very long until the bubble burst; — and the curious incident^
of the hallucination now only serve

" To point a moral, or adorn a tale."

At some future day, and under different circumstances, it is quite
possible that a portion of our population may find the Silk-culture
an eligible business, and the Morus multicaulis a valuable little tree.

386. BROUSS01VEVTIA, Vent.

[Dedicated to P. N. V. Broussonet,— a French Naturalist.]
Flowers dioicous : STAM. FL. in loose ament-like spikes? bracteate. —
Calyx 4-parted. PISTILLATE FL. in dense capitate clusters, mixed
with hairy scales. Calyx urceolate, 3- or 4-toothed. Ovary 1-
celled, pedicellate; style 1, filiform,, eccentric, stigmatic on one side.
Akene softly fleshy, elevated on the baccate pedicel, which is sup-
rounded at base by the calyx.

1. B. PAPYRIF'ERA, Vent. Leaves roundish-ovate, or subcordate,
acuminate, serrate, often lobed, roughish above, pubescent beneath.
PAPEB-PBODUCING BBOUSSONETIA. Paper Mulberry.

Stem 15 to 20 or 25 feet high, with spreading hranches, and tough bark on the
twigs. Leaves 3 to 6 or 8 inches long ; petioles 1 to 3 inches in length. Staminate
spikes about 2 inches long. Pistillate flowers densely crowded on a globose
receptacle.
ffab. Streets, and yards. Nat. of Japan. Fl. May. F.r.

Obs. The staminate plant was introduced, here, some 60 years
since, as a shade tree ; but it is inferior to many others in beauty, —
and so prolific in troublesome suckers, that it is now becoming ob-
solete. The pistillate plant (especially in fruit) is said to be a
handsomer tree ; but it has been introduced so recently, that its
character is scarcely known among us.

SUBORDER II. CANNABIN'EAE.

Herbs, with a watery juice; erect and annual, — or twining and perennial.
leaves usually opposite, and stipulate ; flowers dioicous, — the staminate ones race-
mose, or paniculate, with 5 sepals imbricated in the bud, — the pistillate ones
clustered, either with single bracts, or with numerous bracts imbricated in stro_
bile-like aments; stigmas 2, elongated; fruit a nut, or akene; embryo curved,
destitute of albumen,

387. CAflT'STABIS, Tournef.
[An ancient Greek name,— of obscure etymology.]

STAM. FL. in axillary compound racemes. PISTILLATE FL. spicate-
clustered, with single bracts. Calyx urceolate, acuminate, — con-
sisting of a single membranaceous sepal folded round the subglobose
ovary. Fruit a nut (or caryopsis), ovoid, 1-celled, 2-valved, inde-
hiscent, inclosed in the persistent calyx. Stem erect; upper leaves
often alternate ; flowers greenish.

pubesceut, often branched. Leaflets 3 to 5 inches long ; common petioles 1 to 3
inches in length. Staminate flowers in loose pedunculate axillary clusters, rather
crowded in a kind of dense panicle at summit. Pistillate flowers axillary, sessile;
mostly in pairs. Stigmas long, slender, densely pubescent, somewhat tawny.
flab. Fields, &c. : very rare. Nat. of Persia. Fl. June. Fr. Aug.

Obs. This plant — so important in Commerce and the Arts — was
formerly one of the regular crops, with many of our farmers; but
it is now scarcely entitled to be enumerated among the cultivated
plants of Chester County.

388. HITUUJMIS, L.

[Latin, Humus, mould, or moist earth ; in allusion to its place of growth.]
STAM. FL. in loose oblong axillary panicles. PISTILLATE FL. in
short axillary and solitary strobile-like aments ; bracts foliaceous,
imbricated in several rows, each 2-flowered. Calyx a single mem-
branaceous scale-like enlarging sepal, — its folded margin embracing
the ovary. Akene 1-celled, invested with the enlarged calyx, which
is sprinkled with orange-colored resinous atoms, and, together with
the bracts, forming a membranaceous cone, or ovoid-oblong ament.
Stem twining (with the sun — or E. S. West) ; upper leaves often alter-
nate ; flowers greenish.

1. H. LU^PULUS, L. Stem retrorsely aculeate ; leaves mostly 3-lobed,
cordate at base, petiolate, very rough.
LITTLE-WOLF HUMULUS. Common Hop. Hop-vine.

Perennial. Stem 10 to 15 or 20 feet long, several from the same root (or rhizoma),
slender, somewhat angular and twisted, branched above. Leaves 3 to 5 inches
long ; petioles 1 to 3 inches in length. Pistillate cones proverbially numerous and
crowded (" as thick as hops"), pendulous, 1 to 2 inches in length, at maturity ;
bracts broadly ovate, acuminate.
Sab. Gardens, &c. Fl. July. Fr. September.

Obs. This plant — though cultivated (i. e. the pistillate one) in
almost every garden — is undoubtedly indigenous along our streams.
The uses and value of the cones (or rather of the bitter resinous
atoms, with which they abound,) are well known. The pistillate
plant, in cultivation, being usually remote from the staminate, I
think the ovaries are commonly abortive.

SUBORDER III. URTPCEAE.

292 GYMNOSPERMOUS EXOGENS

Obs. This tree — though somewhat rare in Chester County — is so
generally diffused throughout North America, that it has been
adopted as emblematic, in Vignettes on Maps, and other devices,
having reference to this Continent. The timber is often cut into
lumber; but is much inferior in value to the White Pine. The
bark is used in tanning leather, — and MARSHALL says, the Aborigines
employed it to dye their splints, for baskets, of a red color. The
young plants, properly managed, make a very beautiful (though
not very effective) evergreen hedge.

the sacred volume — has been recently introduced, and bids fair to
become common, among us. The Deodar Cedar — a graceful Ever-
green, with drooping branches, less rigid and rather longer bluish-
green glaucous leaves — has been also introduced ; and apparently
belongs to this section.

Obs. The turnep-shaped rhizoma (called a Cormus,} is very acrid,
when recently gathered ; but that quality is dissipated, in great
measure, by boiling, or drying.

Swedes of that day, called it "Taw*-kee;" and that the Indians
plucked the seeds, and kept them for mating.

405. A'CORUS, L.

ENDOGENOUS PLANTS.

ORDER C. LEMNAVCEAE.

Minute stemless herbaceous aquatics, floating free on stagnant pools ; leaves, as well
as stem, substituted by a flat/rond, which produces 1 or 2 monoicous florets from a
chink at the edge, or upper surface, — and a few pendulous radicles from the under
surface; stamen 1 ; fruit utricular; embryo straight, in the axis of fleshy albumen.
Of this remarkable Order, Prof. A. GRAY observes: "Fructification much as in the
Arum Family, of which these plants are minute and greatly reduced forms."

4O6. LEM'tfA, L.

[An ancient Greek name; of uncertain meaning.]

Flowers 3 together, in a cleft in the edge of the frond, bursting
through a thin membranaceous urceolate spathe; two of them con-
sisting of single stamens (one preceding the other), with thread-like
filaments, and 2-celled anthers; the third floret a 1-celled ovary ;
ovule mostly solitary, erect; style elongated, recurved; stigma fun-
nel-form. Utricle 1 -seeded, indehiscent. Annuals. Fronds laterally
proliferous by a kind of buds formed in the chinks, as well as prop-
agated by seeds ; roots with a sheath-like appendage on the end ;
flowers microscopic, rarely found (never yet, in this country. Prof.
A. GEAY).

t Fronds learing single roots; ovule solitary.

!• tj» minor, L. Fronds roundish-obovate, or oval, sessile, thick-
ish, proliferous from near the base.
LESSER LEMNA. Duck's-meat. Duck-weed.

Fronds about a line, or line and half, in length, slightly convex beneath, some-
what succulent, green. Soot a solitary fibre, from the centre of the frond, rather
elongated.
Hob. Pools, and stagnant waters: frequent. Fl. Fr.

Obs. These singular little plants, as ENDLICHER remarks, are
"nemini non cognitae" — known to every body, — especially this
species; but they are so minute, that their organs are seldom seen,
and are imperfectly understood.

%. I*, trisulca, L. Fronds elliptic-oblanceolate, petiolate, thin,

THREE-FURROWED LEMNA.

Fronds % to % of an inch long, nearly pellucid, finally elongated and narrowed
at base to a slender tail, or petiole, obtuse at apex, proliferous from near the mid-
dle of the sides, so as to form crosses. While these lateral fronds remain sessile,
they present the appearance of a 3-lobed leaf.

ORDER CL TYPHACEAE. ,* 7

Marsh herls: leaves sessile, sheathing at base, narrow-ensifonn, or linear; flower*
monoicous. in a dense oylindric spadix-like spike, or glomerate in Twads, destitute
of proper floral envelopes; fruit nut-like, or a sort of dry drupe, indehiscent,
mostly 1-seeded; seed suspended; embryo straight, in copious albumen.

401. TYVPHA, Tournef.
[Or. Tiphos, a bog, or marsh; from its place of growth.]
Flowers in a long dense terminal cylindric interrupted spike, or
spadix, with an intervening caducous spathe, — the upper portion
consisting of stamens only, intermixed with simple hairs, — the lower
consisting of ovaries surrounded by numerous clavate bristles ; style
simple ; stigma unilateral, tongue-shaped. Nutlets minute, pedicel-
late. Smooth perennials: rhizoma creeping; stems, or culms, sim-
ple, without nodes (except at base, where the leaves originate) ;

long as the spike. Pistillate spike 4 to 6 inches long, % an inch to % in diameter,
greenish-brown.
Hob. Borders of pools: frequent. Fl. June. Fr. Sept.

Obs. The leaves of this plant were formerly used, by Coopers, to
secure the joints in the heads of casks from leaking; and the hairy
fruit, from the mature spikes, is sometimes collected by poor people
to fill their beds. It is, however, a miserable substitute for feath-
ers, or hair, — and even for clean oats chaif, corn-husks, or cut straw.

near the base ; staminate and pistillate portions of the spike a little
distant.

06s. This belongs to a notable tribe of inert medicinal plants,
which — once in an age, or so — dabblers in quackery have the address
to impose upon the credulous, as being endowed with marvellous
virtues, in incurable or desperate stages of disease. Some years
ago, — after Anagallis, and Scutellaria, had become rather obsolete,
as Newspaper cures for that terrible malady, Hydrophobia, — the
Alisma was proclaimed, through the Gazettes, as a certain remedy;
and persons who ventured to express a doubt, were scarcely tolera-
ted, by the editorial fraternity ! This specific, however, soon shared
the fate of its predecessors ; and will probably be no more heard of,
until a future race of Empirics, in the cycle of "Progress," shall

ously 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." The fertile scapes
then "coil spirally and draw the ovary under water to ripen." —
WILSON, in his Ornithology, says the root is a favorite food of the
Canvass-back Duck, — to which the peculiarly delicate flavor of the
flesh of that bird has been ascribed. The bunches of long dark-
green leaves, which are usually procumbently floating, afford a
hiding-place for Eels, — whence one of its common names. In refer-
ence to this plant, Dr. DARWIN indulges in the following imagina-
tive strains : —

" As dash the waves on India's breezy strand,

Her flush'd cheek press'd upon her lily hand,

VALUSNER sits, upturns her tearful eyes,

Calls her lost lover, and upbraids the skies ;

Tor him she breathes the silent sigh, forlorn,

Each setting day ; for him each rising morn :—

HYDROCHARIDACEAE 307

Bright orhs, that light yon high ethereal plain,
Or batfce your radiant tresses in the main;
Pale moon, that eilver'st o'er night's sable brow ;
For ye were witness to his parting vow !
Ye shelving rocks, dark waves, and sounding shore,—
Ye echoed sweet the tender words he swore ! —
Can stars or seas the sails of love retain?
0 ! guide my wanderer to my arms again ! "

My excellent Friend, E. I>URAND, has sent me the following Lines
by a French Poet and Botanist, which may be appropriately annexed
to the preceding : —

" Le Rhdne impgtueux, sous son onde Scumante,
Durant six mois entiers nous derobe une plante
Dont la tige s'allonge en la saison d'amour,
Monte au dessus des flots et brille aux yeux du jour.
Les males dans le fond jusqu'alors immobiles,
De leurs liens trop courts brisent les noeuds debiles,
Toguent vers leur amante, et libres dans leurs feux,
Lui forment sur le fleuve un cortege nombreux :
On diralt une fete ou le dieu d'hym6nee
Promene sur les flots sa pompe fortunSe ;
Mais les temps de Venus une fois accomplis,

La tige se retire en rapprochant ses plis,

Et va murir sous 1'eau sa sentence feconde." —

ORDER CV. ORCHIDACEAE.

Perennial herbs ; roots often bulb- or tuber-bearing, — sometimes fascicled, thick-
ened and fleshy ; stems or scapes mostly simple, often leafless or with mere sheaths ;
leaves alternate, parallel-nerved, entire, sheathing at base, often subradical and
crowded ; flowers perfect, irregular ; perianth adherent below to the ovary, — the
lorder of 6 divisions, in 2 sets ; the 3 outer (sepals) of the same petal-like appear-
jmce as the 3 inner (petals),— of which inner set, the upper, or posterior one— hut,
by the twisting of the ovary, or peduncle, generally appearing to be the lower, or
anterior one— differs more or less in shape or direction from the others, is often
spurred or appendaged, and is called the Up ; stamens normally 3, with but 1, or
rarely 2, perfect, gynandrous (i. e. adherent to the style, and forming together the
central column); potten either in waxy masses, or in loose granular, or mealy
clusters (pollinid) ; ovary 1-celled, with 3 parietal placentae ; fruit a £valved cap-
sule ; seeds numerous, minute, resembling fine saw-dust, destitute of albumen.

thin white shining membranaceous margin.
Hab. Thickets ; fence-rows, &c.: frequent. Fl. June. Fr. Octo.

Obs. I have observed, in the pistillate flowers, 6 abortive stamens,
or staminodia ; but do not know whether they are constant. The
fine tuberous rhizoma, known as the Yam, in tropical countries, is
afforded by a species of this genus (D. saliva, L.).

eter, on peduncles 3 to 5 inches long.
Hib. Meadows; fence-rows, &c. : frequent. F Z.May. Fr. Sept.

Obs. This plant is easily identified by the abominable foetor of
its flowers, — which, however, is completely dissipated by drying.

SUBORDER II. TRILLIA^CEAE.

Hob. Rich, moist, shaded grounds; thickets, &c.: frequent, Fl. May. Fr. Aug.

Obs. There seems still to be some confusion in the synonymy of
this plant, — in consequence of PURSH having mistaken it for the true

Obs. This foreigner has escaped from the gardens, in many
places, — and although it perfects but few seeds, it multiplies its
bulbs so rapidly, as to be a great annoyance to the tidy farmer.
The bulbs of this species are said to be much used for food, in the
Levant; and LINNAEUS imagined them to be the "Dove's Dung,"
which was sold so dear at the siege of Samaria, as mentioned in the
2nd book of Kings, Chap. VI. (See HOOKER & ABNOTT'S British
Flora). Some of our Agriculturists could furnish almost any quan-
tity,— and, I imagine, would gladly part with them, at a very low

Obs. Often cultivated, — as a domestic remedy for worms, in child-
ren. I suppose it to be the species so much esteemed by the
" garlic-eating Peasantry" of Spain. I incline to think these bulb-

Hob. Fields, and meadows. Nat. of Europe. Fl. June. Fr. Aug.

Obs. Tradition says, this species was brought by the first Welsh
Immigrants to Pennsylvania, for the purpose of supplying an early
spring pasture. It is now completely naturalized, — and, in some
districts, so abundant as to be quite a nuisance. It not only im-
parts a disgusting flavor to milk, butter, &c>, but, when the bulblets
are abundant among wheat, they seriously injure the flour, and
render the manufacture of it difficult.

To rain a shower of commanded tears,
An Onion will do well for such a shift;
Which in a napkin being close conveyed,
Shall in despite enforce a watery eye." — Taming of the Shrew.

Obs. Occasionally cultivated, in the Kitchen gardens, as an in-
gredient in soups, &c. It seems to be regarded as a sort of national
Emblem, by the Welsh ; and is thus noticed by the Poet, GAT :— r

Of Irish swains Potato is the cheer ;
Oats for their feasts the Scottish shepherds grind."

NARROW-LEAVED COMMELYNA. Day-flower.

Plant nearly glabrous, annual? Stem about a foot long (3 or 4 feet when sup-
ported, in hedges, &c.), terete. Leaves 2 to 4 or 5 inches long, and half an inch to

Obs. I have specimens of C> angustifolid, from the South, with
really narrow lance-linear leaves ; yet ours, with its lanceolate
leaves, seems to be referred to the same species. Three of the
anthers are completely abortive and cross-shaped, — and a fourth one
is partially so modified, or in process of metamorphosis to that
state. The authorities all appear to concur in calling the plant a
perennial : but I-am much mistaken if the one with us is not an
annual. It was accidentally introduced to this Borough, about
thirty years since, from the Garden of the late JOHN JACKSON, of
London Grove; and is gradually extending itself. Miss ABBY
KIMBER informs me, that it has also .been found at Kimberton, in
this County.

and closed round the culm so as to form an entire sheath, — sometimes the lamina,
or blade, wholly wanting; flowers perfect, or monoicous (rarely dioicous), in little
bracteate clusters (called spikelets),— usually one flower in the axil of each of the
glume-like imbricated bracts, or scales; perianth (in this Order, for convenience,
termed a perigynium,) none,— except in some pistillate diclinous flowers (as Garex),
where it is a membranous or glumaceous sac,— or sometimes, in perfect flowers,
the perianth seems to be substituted by some minute scales, or by a verticil of
hypogynous&mto,* or soft hairs; stamens usually 3 ; ovary 1-celled, with a single
erect ovule,— in fruit becoming an akene, or caryopsis, which is lenticular, or trique-
trous, according as the style is bifid, or trifid ; embryo minute, inclosed in the base
of copious farinaceous albumen. An Order comprising some 50 genera,— remark-
able for their little value to the Agriculturist; and also for their prevalence being
an indication of swampy, neglected, or unpromising soil.

TRIBE 1. CYPEREVAE.

[An ancient Greek name ; of obscure meaning.]

Spikelets usually compressed, variously aggregated and arranged. _
Scales often decurrent at base. Perigynium entirely wanting. _

*The distinguished Authors of the British Flora (ed. 6.) allege, that "those
bristles cannot be & perianth, because they are situated between the anther-bearing
stamens and the ovary."

and requires prompt attention, for it multiplies rapidly. It is, how-
ever, not quite so bad as the C. Hydra, of the South. Although

Obs. This pretty and rather remarkable species, was at one time
so rare, in European collections, that many applications were made
to Dr. MUHLENBERG for specimens, — which, he not being able to
furnish, led to the conclusion, with some, that no such plant existed.
It is, however, quite abundant in some localities in this County.

ORDER CXVIII. GRAMIN'EAE.

TRUE GRASSES: chiefly herbaceous; often cespitose; rhizomas slender, creeping,
ramifying, with filiform radicles ; culms terete, nodose and leafy, mostly hollow
between the nodes; leaves entire, with parallel nerves, distichously alternate,
apparently sessile, — the petioles being dilated, and sheathing the culm, but slit on
the side opposite the lamina, or blade, down to their origin at the nodes (i. e. their
margins are not united, as in the Cyperaceae) ; stipules axillary, adnate to the
petiole, with the scarious summit often free, and known as the ligule; flowers
perfect, polygamous, or monoicous (rarely dioicous), in little spikelets at the ends

GBAMINEAB 355

of the branches, and these spikelets disposed in loose panicles, or condensed into
racemes, or spikes ; spikelets 1- 2- or many-flowered, formed of distichously imbri-
cated chaffy bracts (stunted or modified sheaths of abortive leaves)*,— of which the
outer, or lower ones, are called glumes, and the two that immediately inclose each
floret are termed paleae (the inner, or upper palm usually 2-ribbed, and supposed
to consist of 2 united paleae) ; proper perianth none ; stamens 1 to 6, or more —
usually 3 ; anthers versatile ; ovary 1-celled, 1-ovuled, — usually with 2 minute
fleshy scales at base, somewhat analogous to the bristles or hairs (perigynium), in
the Cyperaceae ; styles or stigmas 2, plumose, or pencil-form, mostly with simple
hairs ; fruit a seed-like grain (called a caryopsis), free, or sometimes adherent to
the paleae, — the pericarp thin, and for the most part closely adnate to the seed ;
embryo at the base, and on the outside, of copious farinaceous albumen.

This vast Order is probably the most generally diffused, and the most important
to Man, of all the families of plants. The seeds, and herbage, furnish a principal
portion of the food of the human race, and of the more valuable domestic ani-
mals : Or, as it is expressed in the terse and classical Latinity of ENDLICHER— >

Hob. Swamps, and along sluggish rivulets : common. JFl. Aug. Fr. Sept.

Obs. A very rough, white-panicled grass, — common along slug-
gish streams ; rather a nuisance, than otherwise.

* The glumes and paleae (or what is called Chaff) of the Grasses are the crowded
vestiges of the sheaths of leaves. The awns, often found on the paleae, are the
midribs, or slender remains of the laminae, or blades of the leaves ; and when
these awns are apparently inserted more or less distant from the apex of the
paleae (or dorsal, as it is termed), it is probably owing to the extension and per
sistency of the ligult of the sheath,— which ligule thus becomes a portion of the
paleae.

long as the florets (though scarcely perceptible on the young panicle).
Sab. Swamps; Wynn's meadows, Brandy wine: rare. Fl. Aug. Fr. Sept.

Obs. This stout grass — which attains to the usual size of Broom,"
corn — seems to be common to both hemispheres. It is, however, of
little value in agriculture. A nearly allied plant (Arundo Donax, L.)
is often seen in the yards and gardens of the curious, under the

Obs. Cultivated to some extent, and naturalized among us. It is
more valued for pasture, than for hay. It is of quick growth, and
is speedily reproduced after being cut, or eaten down by Stock : so
much so, that we may almost literally apply to it the lines of
VIRGIL —

" Et quantum longis carpent armenta diebus
Exigua tantum gelidus ros nocte reponet." — Georg. 2.

4» P.pratensis, L. Culms erect, terete and, with the sheaths, smooth ;
ligule short, truncate; spikelets 3- to 5-flowered; florets conspicu-
ously webbed.
MEADOW POA. Smooth Meadow-grass. Green-Grass.

Perennial. Culms 1 to 2 or 3 feet high. Radical leaves often very numerous,
and very long (1 to 2 feet, or more, in rich soils), scarcely a line wide, and exactly
linear, terminating abruptly in a boat-shaped or keeled point, deep-green, — culm
leaves shorter than the sheaths. Panicle at first rather contracted, finally expand*
ing and pyramidal.
Sab. Fields, meadows, &c. Nat. of Europe. Fl. May. Fr. July.

Obs. This varies greatly, in size and appearance, when growing
in different soils and situations. It is believed to be a foreigner ;
but is thoroughly naturalized. In our best soils, the radical leaves
are very luxuriant, — when it is known by the name of "Green-
Grass." It is the profusion of the nutritious radical leaves, which
constitutes the chief excellence of this grass, — which is, indeed, the
most valuable known in our pastures. The slender culms afford a
good material for the manufacture of Leghorn hats.

5. P. compressa, L. Culms ascending, much compressed and, with
the sheaths, smooth ; panicle contracted, somewhat one-sided.
COMPRESSED POA. Blue-Grass. Wire-Grass.

Perennial. Rhizwnas branching and creeping. Culms 9 to 18 inches long,
oblique and geniculate, often procumbent and radicating at base. leaves 2 or 3 to
5 or 6 inches long, linear, keeled, and, with the culm, of a bluish-green, or glau-
cous hue. Panicle at first almost spicate, finally expanding; spikelets 5- or 6-flow-
ered, often purplish.
Sab. Fields, and pastures. Nat. of Europe. FL June. Fr. July.

Obs. This species is also thoroughly naturalized, and is universally
known, here, by the name of Blue-grass, — though, in Kentucky, that
name is given to the preceding (our Green- Grass). It affords much
less pasture than the Green-Grass, — and therefore is less valuable;
but what there is, is believed to be even more nutritious. The
rhizomas are exceedingly tenacious of life, — which renders the grass
rather troublesome, in cultivated grounds, among other crops.

486. ERAGROS'TIS, Beauvois.

Spikelets nearly as in Poa, few- or many-flowered, in an open panicle.
Glumes unequal. Lower palea 3-nerved, not webbed at base, — the
upper one persistent on the rachis. Chiefly annuals: culmt often
branching, geniculate and oblique, or sometimes creeping j ligult
ehort, often bearded.

Obs. This foreigner is a well-known intruder among our crops of
Wheat and Rye, — and often appears in the same fields, for a year
or two, after those crops ; but, being an annual, it is soon choked
out by the perennial grasses. The vulgar error, that this plant is
transformed Wheat, came to us with the earliest Immigrants, — and,
notwithstanding the boasted "march of mind," it yet prevails among
a certain class of our farmers, to a considerable extent. Any one,
however, who has had an opportunity to observe the uniformity and
constancy of the Laws which govern the development of living
bodies, and yet persists in believing in the transmutation of genera
and species, may be fairly placed in the category of him who be-
lieves in equivocal generation, — of whom it is said, in the Amoenitates

Obs. This has been introduced, as suitable for Lawns, &c. and

FLEET says, "many are tempted by the facility of procuring the
seed of this grass to lay down grounds near their houses, where
they want to have a fine turf with it ; for which purpose, unless
the soil be very rich, a worse grass cannot be sown, as it will
certainly die off in a very few years intirely."

florets shorter than the glumes, naked at base.
CULTIVATED AVENA. Common Oats.

Annual, Culm 2 to 4 feet high, smooth, and rather soft. Leaves 6 to 15 inches
long, rough; sheatlis smooth, somewhat loose; ligule lacerate. Spikelets all pedun-
culate ; lower floret mostly awned near the bifid apex ; upper floret awnless, — with
a pedicel at the base of the upper palea, bearing at its summit membranaceoua
rudiments of a third floret. Grain closely invested by the smooth, shining, sub-
coriaceous paleae, and slightly adherent to the upper one.
Hob. Fields. Native Country uncertain. Fl. July. Fr. Aug.

Obs. The great English Lexicographer defined Oats as being the
food of Horses, in England, — and of People, in Scotland. Dr. DARWIN,
also, seemed by the following couplet, to regard the plant as some-
what Scottish, in its associations: —

" Two Sister-nymphs, the fair AVENAS, lead
Their fleecy squadrons on the lawns of Tweed."

The Founders of the Edinburgh Review had reference to the same
Johnsonian idea, when they thought of adopting for a motto —
" Tenui Musam meditamur Avend."

And it was, doubtless, while those Reviewers were supping their
thin Parritch, that the interesting inquiry occurred to them — "Who
reads an American Book?"* On our side of the Atlantic, the
Avena is cultivated almost entirely as a pabulum for Farm Stock, —
and has, as yet, very little connection with our Literature.

DIVISION II. PHALARID'EAE.

Spikelets more or less panicled, somewhat 3-flowered, with the middle floret, only,
perfect, — the lower and terminal ones (or the apparently lateral ones) imperfect —
either staminate, rudimentary, or neutral ; or sometimes the terminal floret, per-
fect, and the two lower ones imperfect.

Jl. Middle floret perfect.
498. ARRHEtf ATHEVRIJM, Beauvois.

[Gr. Arrhen, male, and At her, awn ; the staminate floret being awned.]
Spikelets 2-flowered, with the rudiment of a third, terminal one ;
middle floret perfect, — the lower palea convex, with a short awn near
the slightly bifid apex ; lowest floret staminate only, — the lower
palea convex, bearing a long twisted awn on the back, below the
middle ; otherwise nearly as in Avena.

1. A. AVENACEUM, Beauv. Leaves flat; panicle linear-oblong, con-
tracted, finally spreading ; glumes unequal, — the lower one shorter
than the florets.

* Since that inquiry was made, however, it js believed that gome American
Books have been read ; and, it is said, some curious people have even been seen
going to look at an "American Statue."

378 ENDOGENOUS PLANTS

Obs. This has been introduced, and occasionally cultivated, under
the absurd misnomer of " Grass of the Andes;" but it is not likely
to become a favorite, with our farmers. It is partially naturalized,
in some neighborhoods.

499. HOI/CUS, L.

[An ancient Greek name, — of obscure meaning.]

Spikelets 2- to 3-flowered, — the florets pedicellate, so as to appear
side by side, shorter than the membranaceous glumes. Lowest floret
neutral, or obsolete ; middle one perfect, chartaceous, and awnless ;
upper one staminate only, awned near the tip. Grain free, smooth.

1.77. landtus, L. Softly hoary-pubescent; panicle oblong, rather

contracted ; awn of the staminate floret recurved, included in the

glume.

WOOLLY HOLCUS. Feather-grass. White Timothy.

Perennial. Culms \% to 2 feet high. Leaves 3 to 6 inches long; liguLe -white,
truncate, dentate. Panicle 2 to 4 inches long, somewhat dense, whitish, tinged
with purple ; glumes roughish-pubescent ; florets smooth and shining.
Hob. Moist meadows. Nat. of Europe. Fl. June. Fr. July.

Obs. Extensively naturalized ; but not esteemed by our Farmers.
§2. Terminal floret perfect, and awnless, — sometimes diandrous.

5OO. AtfTHOXAlVTIIUM, L. <K

[Or. Anfhos, flower, and anthon, of flowers ; flower of flowers', fide A. Gray.']
Spikelets in a condensed, oblong, spike-form panicle, — each spikelet
somewhat 3-flowered, but the lower two (or apparently lateral) florets
neutral, consisting merely of a narrow palea, which is hairy, and
awned on the back ; the terminal (or central) floret diandrous, with
2 short, smooth, shining paleae. Glumes very unequal, thin, acute,
keeled. Grain smooth, closely embraced by the paleae.

1. A. odordtum, L. Spikelets somewhat fascicled on short peduncles ;

paleae of the neutral florets ciliate.

FBAGRANT ANTHOXANTHUM. Sweet-scented Vernal-grass.

Perennial. Cidms 9 to 18 inches high, slender. Leaves 2 to 6 inches long,
pubescent; sTieaths nerved; ligule elongated. Panicle a sort of loose spike, 1 tOs
2 or 3 inches in length, becoming yellowish when mature.
Sab. Moist grounds. Nat. of Europe. Fl. May. Fr. July. fc».^ -

Obs. This has been much noticed, in Europe, as a fragrant
meadow-grass ; but it seems to affect a thin, moist soil, — and is by
no means regarded, here, as a grass of superior value. When cut,
and partly dry, it emits an agreeable odor — often remarkable in
new-mown hay. The culms have been used in the manufacture of
imitation Leghorn hats. This is the grass so fancifully referred to,
by Dr. DARWIN, in the following lines of the Botanic Garden.

" Two gentle shepherds, and their sister-wives,
With thee, ANTHOXA ! lead ambrosial lives ;
Where the wide heath in purple pride extends,
And scatter'd furze its golden lustre blends,
Clos'd in a green recess, unenvi'd lot !
The blue smoke rises from their turf-built cot ;
Bosom'd in fragrance blush their infant train,
Eye the warm sun, or drink the silver rain."

GRAMINEAE 379

501. PHAI/ARIS, L.

[Or. Phalos, shining; alluding to the shining florets, or paleae.]
Spikelets in a dense panicle (sometimes spiked), — each spikelet con-
sidered as 3-flowered, but the two lower (or lateral) florets mere
neutral rudiments, at the base of the perfect one. Glumes nearly
equal, boatshaped, nerved. Paleae shorter than the glumes, finally
coriaceous, and shining, closely investing the smooth grain.

1. P. arundin&cea, L. Panicle oblong, with the spikelets
clustered, and somewhat secund, on the branches ; glumes obtusely
keeled ; neutral rudiments hairy.
HEED-LIKE PHALARIS.

green nerves ; paleae, pilose with appressed hairs ; anthers yellow ; grain, obovate,
dark brown.
Hob. Swampy rivulets, and ditches : frequent. Fl. June. Fr. July.

Obs. This is a fine-looking, deep-green grass, — but is not regarded
as of much agricultural value. Is it really native ? The foreign
var. picta, with striped leaves — called Ribbon-grass — is often seen in
gardens. The P. Canariensis, L. with ovate spikes, is also some-
times cultivated, for the seeds, to feed birds.

DIVISION III. PANFCEAE.

Spikelets 2-flowered, but the lower floret always imperfect (either staminate, or
neutral),— often reduced to a single empty palea, or glume ; grain compressed, —
or sometimes grooved on the back, with the embryo at the bottom of the groove ;
flowers often polygamous, or monoicous.

TRIBE 7. PANFCEAE PROPER.

Paleae of the fertile florets coriaceous, or chartaceous, awnless, not keeled, em-
bracing the smooth grain, flattened parallel with the herbaceous glumes.

A. Spikelets appearing simply \-flowered, from, Vie suppression of ttie lower glume
(an empty palea occupying its place).

502. PAS'PAL,IJ]Tl, L.

[Gr. Paspalos ; said to be an ancient name for Millet.]
Spikelets racemose-spiked, usually in 2 rows, on one side of a
flattened continuous rachis, jointed with their very short pedicels,
plano-convex, and nearly orbicular. Glume and empty palea few
nerved. Perennials : culm erect, smoothish ; spikes single, digitate,

Spikelets sometimes spiked, or racemose, — usually panicled. Glumes
unequal, — the lower one short, or minute, sometimes wanting. —

of a single palea, which resembles the upper glume. Upper floret
perfect, coriaceous, inclosing the free and grooveless grain. Stamens

3. Stigmas plumose, usually purple.

gl. DIGITARIA: Annuals: Spikelets crowded 2 or 3 together, in simple one-sided
digitate-fascicled spikes; neutral floret with a single palea; lower glume

Hob. Gardens, and lota. Nat. of Europe. FL July. Fr. Aug.

Obs. The Grasses of this Section (Digitaria) are probably all
introduced, — at least into this region. This is a very troublesome
one, in the latter part of summer, in Gardens and cultivated lots ;
and, like the most of the Panicums, is little worth, in an agricul-
tural point of view.

2. P. glabrum, Gaudin. Culms procumbent and spreading, rarely
radicating ; spikes 2 or 3 to 6 ; upper glume nearly as long as the
floret.

Obs. This pestilent grass is, happily, yet rare in our County;
but is gradually extending itself, — and, if not vigilantly watched,
will one day be found a great nuisance, around our dwellings. It
is very abundant in the sandy districts of New Jersey ; but whether
indigenous there, I cannot say.

Obs. Long culture has produced several varieties of this noble
Grass, — with grains of differant form and color. There is also a
remarkable vanity— fre^nt, I believe, in the South west — in which
a kind of hu^k, or involucre, is developed around every grain, or
sp'kelet, on the receptac'e. The Goethean theory of the modification
of leaves, at the successive stages of the vegetable progress, from
cotyledons to flowers, is well illustrated by the envelope, or " husk,"
of an Etr of Indian Corn. Few heedless observers would be apt to
recognize the fact, that the several portions of that envelope are
the sheaths of abortive leaves : and yet nothing is more obvious, when
we examine them by the light of that theory. The spike of pistil-
late flowers is supported on a short axillary branch, with numerous
nodes, and very short internodes. As nodes are the points at which
leaves originate, we accordingly find a leaf — or rather the sheathing
petiole of an imperfect one^-at each node of this short flowering-
branch ; and as the nodes are very close together, the sheaths
necessarily over-lap one another,— and thus furnish a manifold
wrapper to the spike of flowers and fruit (i. e. the "Ear"). That
these several layers of the envelope are the sheathing portions of
abortive leaves, is demonstrated by the laminae, more or less de-
veloped, at their summits, — and which, indeed, are sometimes seen
expanded to nearly half the size of an ordinary full-grown blade. —
The sam3 doctrine applies to the chaff, or floral coverings, of all the
Grasses;* as it does, in fact, to those of all the flowering tribes.

upward by an axis or stem, emitting roofs downward, and usually
furnished with distinct leaves (sometimes the stem and foliage con-
fluent into a frond).

ORDER CXXIII. MUS'CL

Low tufted plants, mostly perennial, -with a stem and distinct (sessile) leaves, — pro-
ducing spore-cases (or capsules) which usually open by a terminal lid (operculum),
and contain simple spores only.^

SUBORDER I. BRYA^CEAE.

Calyptra, circumscissed at base ; fruit terminal, or lateral ; lid opening elastically,
or sometimes indehiscent ; orifice of the capsule naked, or more commonly with
aperistome; columetta manifest.

DIVISION I. ACROCAKPI : Pedicel or fruitstalk terminal.

* For the Mosses and Hepaticae of Chester — so far as they are yet known — I am
indebted to my friend THOMAS P. JAMES, of Philadelphia, — an acute and zealous
Bryologist, who (as his other engagements permitted,) has diligently explored the
ANOPHTTES of our ancient Bailiwick ; and has, morever, prepared and presented to
the CJiester County Cabinet of Natural Science, an elegant Collection of those in-
teresting little plants. The intelligent reader will perceive that the descriptions
are chiefly derived from the Contributions of that eminent Botanist, WILLIAM S.
SULIJVANT, Esq. to GRAY'S MANUAL.

t The reproductive organs of the MOSSES are of two kinds:—"!. The sterile flower ,
consisting of numerous (4 — 20) minute cylindrical sacs (antheridia), which dis-
charge from their apex a mucous fluid filled with oval particles, and then perish.
2. The fertile flower, composed of numerous (4—20) flask-like bodies (pistittidid),
each having a membranous covering (calyptra), terminated by a long cylindrical
funnel-mouthed tube (style). The ripened pistillidium (seldom more than one in
a flower maturing,) becomes the capsule, which is rarely iudehiscent, or splitting
by 4 longitudinal slits, but usually opens by a lid (operculum) : beneath the lid,
and arising from the mouth of the capsule, are commonly either one or two rows
of rigid processes (collectively the peristome), which are always some multiple of
4; those of the outer row are called teeth — of the inner, cilia. An elastic ring of
cells (annules) lies between the rim of the capsules and operculum. The powdery
particles filling the capsule are spores. The thread-like stalk (pedicel, or seta,)
supporting the capsule is inserted into the elongated torus (vaginula) of the
flower. The pedicel continued through the capsule forms the columella; enlarged
under the capsule it sometimes forms an apophysis. The calyptra, separating
early at its base, is carried up on the apex of the capsule ; if it splits on one side it is
hood-shaped or cuculliform, — if not, it is mitre-shaped or mitriform. Intermixed
with the reproductive organs are cellular jointed filaments (paraphyses). The
leaves surrounding the antheridia are called the perigonial leaves, those around
the pistillidia or pedicel the perichaetial leaves."— GRAY'S Manual.

spores usually mixed witfi elaters (thin thread-like cells, containing one or two
spiral fibres which uncoil elastically at maturity).*

SUBORDER I. JUNGERMANNIAVCEAE.

Annual, or perennial; frondose, or distinctly leafy, often stipulate (i. e. with
amphigastria); antheridia scattered, free, stipitate or immersed ; pistillidia solitary,
or rarely several, in involucres immediately arising from the stem, or frond, calyp-
trate; capsule mostly 4-valved, pedicellate; spores mixed with elaters, — the elaters
usually with 2 spiral fibres.

TRIBE 1. JUNGERMANNID'EAE.

* The Vegetation of the HEPATICAE is " 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 2 kinds, viz. antheridia and pistillidia, much as
in Mosses (which see), variously situated. The matured pistillidium forms the
capsule, which is either sessile or borne on a long cellular pedicel, and dehiscent
by irregular openings, by teeth at its apex, or lengthwise by 2 to 4 valves. A
columella is rarely present. The perianth is a tubular organ inclosing the calyptra,
which directly includes the pistillidium. Surrounding the perianth are involucral
leaves of particular forms. The antheridia in the foliaceous species are situated in
the axils of pcrigonial leaves."— GRAY'S Manual.

substance, called a thattus.* Some beautiful and valuable Dyes are affor Jed by
plants belonging to this order.

*Tbe following definitions, and cbaracteristic details, are from TUCKEKMAN'S
valuable Synojisis: —

" Perennial, aerial Algae, vegetating only under the influence of moisture,
which is imbibed by the whole surface, propagated by spores (sporidia), and also
by the cells (gonidia) of the green layer.

Thallus (universal receptacle, Ach.) composed of three layers, viz : the cortical,
the medullary, and the gonimous ; evolved from a hypothallus (the elementary
state in which the layers are confused, and discernible afterwards as cylindrical
cells, and also as fibres on the under side of foliaceous Lichenes, and forming the
base, closely adnate to the matrix, in crustaceous ones), typically horizontal or
vertical. The horizontal thallus is either crustaceous (often somewhat lobed at the
circumference or squamulose). or foliaceous (becoming sometimes in degenerate
states crustaceous). The vertical thallus is either compressed (sub foliaceous), or
terete (fruticulosR) ; of both of which the filamentous thallus and the pendulous
thallus are degenerations. In Cladouia and Stereocaulon a vertical thallug
(podetium) arises from the primary horizontal thallus, and is itself often be-
sprinkled with a kind of secondary horizontal thallus in the form of leaf-like scales.

Lichenes are reproduced in two ways; 1. by gonidia, the (normally green) cells
of the green (gonimous) layer, which appear on the surface as irregularly shaped
powdery masses (soredia), and propagate either on the original thallus, forming
foliaceous or squamulose expansions, — or external to the original thallus, forming
new individuals of the parent thallus; and 2. by sporidia, consisting of subglo-
bose or elliptical cells, which are either naked or contained in other elongated more
or less vertical cells (asci), and immersed in the thalamium (or fructification proper),
and propagate new individuals of the species. The thalamium is either rounded,
gelatinous-waxy, and the asci converging (nuclei form), — or flattened at length into
a rigid, persistent, or afterward collapsing lamina (subdisciform), — or originally
disciform (open) ; and is itself contained in a receptacle (exciple), either of the same
color with and like the thallus (thalline exciple), or of different color and nature
(proper exciple). The whole fructification constitutes the apothecium, which is
typically round, though also occurring normally oblong and linear (lirellaeform,)
and is either excavated with a contracted margin (urceolate), — or slightly concave
with an elevated margin (scutettaeform), — or very concave-scutellaeform (cyalhi-
form), — or very concave-scutellaeform and pervious (infundibuliform, — a term
applied also to the pervious cup-bearing podetia of Cladoniae), — or goblet-shaped
and stipitate (crateriform), — or dilated, flat, and without prominent margin
(peltaeform, of which the reniform is a variation). — or convex with repressed mar-
gin (cephaloid), — or between scutellaeform and peltaeform (disciform), — or between
gcutellaeform and cephaloid (tuberculate). When the thalline exciple is prolonged
below into a footstalk, it is said to be pedicellate ; a proper exciple in like manner
prolonged is said to be stipitate. When the proper exciple is originally and typi-
cally closed, the apothecium receives the name of perithecium. In the ANGIOCARPI,
several thalamia are sometimes contained in the same exciple (composite apothecia) ;
and in the GYMNOCARPI, in like manner, several disks are sometimes confluent
(symphycarpeous apothecia). The colors of the thallus in Lichens are disposed by
I'RIES In four series: — 1. from pale green becoming glaucous; 2. from yellowish
green becoming ochroleucous ; 3. from dark green becoming fuscous or olivaceous ;
4. from pale yellow-green becoming lemon -colored. Each series has its peculiar
variation.". The glaucous runs into pale green, ceruleseent, and white; the
fuscous into dark green, olivaceous, cinereous, greyish-fuscous, and dark chestnut;
the ochroleucous into yellowish green and albescent; the lemon-colored into pale
yellow, orange-red, and vermilion-red."

noted, as constituting the principal food of the Rein-deer, in Lapland.
"It is this," says Sir W. J. HOOKER, "which for the greater part
of the year, and especially in winter, is the support of the vast
herds of Rein-deer, — wherein consists all the wealth of the Lap-
landers. No vegetable, LINNAEUS tells us, grows throughout Lapland
in such abundance as this, — especially in woods of scattered pines,
where for very many miles together, the surface of the sterile soil
is covered with it, as with snow. On the destruction of forests by
fire, when no other vegetable will find nutriment, this Lichen
springs up and flourishes, and, after a few years, acquires its full
size. Here the Rein-deer are pastured ; and whatever may be the
depth of snow, during the long winters of that climate, these crea-
tures have the power of penetrating it, and obtaining their necessary
food."

planate, rimose-areolate, olivaceous ; perithecia with a wide base,

globose, emerging and conical at apex, becoming depressed and

umbilicate.

Hob. On limestone rocks : frequent.

Obs. There seems to be some obscurity about this plant ; but I
cannot tell where else to place it. Perhaps it may prove to be
V. nigrescens, Pers.

%. T. CestrenslS, Tuckerm. MS. [Chester'] : Crust conspicu-
ous, chinky, dark blackish- green ; perithecia dimidiate, the base
inflexed, much covered by the thallus, but prominent, globose-

Apoihecia verrucaeform, formed of the thallus, ostiolate-pertuae, containing >u
ono or more perithecia a deliquescent nucleus.

Obs. The term, Sarcothecium, has been employed by FEE, to
denote the medullary substance of the warts, in which the peri-
thecia nestle. It varies in color and intensity with the species, and
affords an obvious character.

We probably have other Trypethelia ; but they have not yet been
determined. It is chiefly a Southern genus.

THALLOPHYTES

Obs. The foregoing Catalogue of Chester County Lichen*, and
Collemas, contains about twenty species never before published in
this country,^ — one half of which are entirely new. For the deter-
mination and description of the most of these, the writer has availed
himself of the kind assistance of his friend E. TUCKERMAN, of
Cambridge, Mass, whose long and assiduous attention to this much-
neglected portion of Cryptogamic Botany has intitled him to be
called THE AMEEICAN LICHENIST.— *E. M.

Obs. A few years since, Messrs. R. KILVINGTON and
DAVIS GARRET, jr. detected a small and very remarkable
shrub, in Willistown, Chester County, which seems evi-
dently to be a Rhus, — but with bipinnate leaves about a
foot long, the pinnae 3 or 4 inches long, and the pinnules
1 to 2 inches in length, linear-lanceolate, more or less
falcate, entire or rarely incised-toothed, glaucous beneath,
the terminal one deeply incised or pinnatifid. Messrs.
KILVINGTON and GARRETT (both of them intelligent and
experienced Florists) are of opinion that the shrub is a
variety of Rhus glabra. If so, it is a curious monstrosity,
or sport of Nature. Although carefully cultivated by
those gentlemen, since its discovery, it has not yet pro-
duced either fruit or flowers ; but Mr. K. informs me,
that it propagates freely by the root.
