PUBLISHERS' PREFACE

TO

GRAY'S SCHOOL AND FIELD BOOK OF BOTANY.

THIS work consists of the " LESSONS IN BOTANY " and the " FIELD,
FOREST, AND GARDEN BOTANY," bound together in one complete volume,
forming a most popular and comprehensive SCHOOL BOTANY, adapted to
beginners and advanced classes, to Agricultural Colleges and Schools, as well
as to all other grades in which the science is taught. It is also adapted for
use as a handbook to assist in analyzing plants and flowers in field study of
botany either by classes or individuals.

The book is intended to furnish Botanical Classes and beginners with an
easier introduction to the Plants of this country, and a much more compre-
hensive work, than the MANUAL.

Beginning with the first principles, it progresses by easy stages until the
student who is at all diligent is enabled to master the intricacies of the
science.

It is a Grammar and Dictionary of Botany, and comprises the common
Herbs, Shrubs, and Trees of the Southern as well as the Northern and Middle
States, including the commonly cultivated as well as the native species in
fields, gardens, pleasure grounds, or house culture, and even the conservatory
plants ordinarily met with

PREFACE.

THIS .volume takes the place of the author's LESSONS IN BOTANY
AND VEGETABLE PHYSIOLOGY, published over a quarter of a cen-
tury ago. It is constructed on the same lines, and is a kind
of new and much revised edition of that successful work. While
in some respects more extended, it is also more concise and terse
than its predecessor. This should the better fit it for its purpose
now that competent teachers are common. They may in many cases
develop paragraphs into lectures, and fully illustrate points which
are barely, but it is hoped clearly, stated. Indeed, even for those
without a teacher, it may be that a condensed is better than a
diffuse exposition.

The book is adapted to the higher schools, " How Plants Grow
and Behave " being the " Botany for Young People and Common
Schools." It is intended to ground beginners in Structural Botany
and the principles of vegetable life, mainly as concerns Flowering
or Phanerogamous plants, with which botanical instruction should
always begin ; also to be a companion and interpreter to the Man-
uals and Floras by which the student threads his flowery way to
a clear knowledge of the surrounding vegetable creation. Such a
book, like a grammar, must needs abound in technical words,
which thus arrayed may seem formidable ; nevertheless, if rightly
apprehended, this treatise should teach that the study of bot-
any is not the learning of names and terms, but the acquisition
of knowledge and ideas. No effort should be made to com-
mit technical terms to memory. Any term used in describing a
plant or explaining its structure can be looked up when it is
wanted, and that should suffice» On the other hand, plans of

structure, types, adaptations, and modifications, once understood,
are not readily forgotten ; and they give meaning and interest to
the technical terms used in explaining them.

In these "Elements" naturally no mention has been made of
certain terms and names which recent cryptogamically-minded
botanists, with lack of proportion and just perspective, are en-
deavoring to introduce into phanerogamous botany, and which are
not needed nor appropriate, even in more advanced works, for the
adequate recognition of the ascertained analogies and homologies.

As this volume will be the grammar and dictionary to more than
one or two Manuals, Floras, etc., the particular directions for pro-
cedure which were given in the " First Lessons " are now relegated
to those works themselves, which in their new editions will pro-
vide the requisite explanations. On the other hand, in view of
such extended use, the Glossary at the end of this book has been
considerably enlarged. It will be found to include not merely the
common terms of botanical description but also many which are
unusual or obsolete ; yet any of them may now and then be encoun-
tered. Moreover, no small number of the Latin and Greek words
which form the whole or part of the commoner specific names are
added to this Glossary, some in an Anglicized, others in their Latin
form. This may be helpful to students with small Latin and less
Greek, in catching the meaning of a botanical name or term.

The illustrations in this volume are largely increased in number.
They are mostly from the hand of Isaac Sprague.

It happens that the title chosen for this book is that of the
author's earliest publication, in the year 1836, of which copies are
rarely seen ; so that no inconvenience is likely to arise from the
present use of the name.

ELEMENTS OF BOTANY.

SECTION I. INTRODUCTORY.

1. BOTANY is the name of the science of the vegetable kingdom in
general ; that is, of plants.

2. Plants may be studied as to their kinds and relationships. This
study is SYSTEMATIC BOTANY. An enumeration of the kinds of vegetables,
as far as known, classified according to their various degrees of resemblance
or difference, constitutes a general System of plants. A similar account of
the vegetables of any particular country or district is called a Flora.

3. Plants may be studied as to their structure and parts. This is
STRUCTURAL BOTANY, or ORGANOGRAPHY. The study of the organs or
parts of plants in regard to the different forms and different uses which
the same kind of organ may assume, — the comparison, for instance, of
a flower-leaf or a bud-scale with a common leaf, — is VEGETABLE MOR-
PHOLOGY, or MORPHOLOGICAL BOTANY. The study of the minute structure
of the parts, to learn by the microscope what they themselves are formed
of, is VEGETABLE ANATOMY, or HISTOLOGY ; in other words, it is Micro-
scopical Structural Botany. The study of the actions of plants or of their
parts, of the ways in which a plant lives, grows, and acts, is the province
of PHYSIOLOGICAL BOTANY, or VEGETABLE PHYSIOLOGY.

4. This book is to teach the outlines of Structural Botany and of the
simpler parts of the physiology of plants, that it may be known how
plants are constructed and adapted to their surroundings, and how they
iive, move, propagate, and have their being in an existence no less real,
although more simple, than that of the animal creation which they support.
Particularly, this book is to teach the principles of the structure and rela-
tionships of plants, the nature and names of their parts and their modifica-
tions, and so to prepare for the study of Systematic Botany ; in which the
learner may ascertain the name and the place in the system of any or all
of the ordinary plants within reach, whether wild or cultivated. And in
ascertaining the name of any plant, the student, if rightly taught, will come
to know all about its general or particular structure, rank, and relationship
to other plants.

iO ELEMENTS OF BOTANY. [SECTION 1,

5 The vegetable kingdom is so vast and various, and the difference is
so wide between ordinary trees, shrubs, and herbs on the one hand, and
mosses, moulds, and such like on the other, that it is hardly possible to
frame an intelligible account of plants as a whole without contradictions
or misstateinents, or endless and troublesome qualifications. If we say
that plants come from seeds, bear flowers, and have roots, stems, and
leaves, this is not true of the lower orders. It is best for the beginner,
therefore, to treat of the higher orders of plants by themselves, without
particular reference to the lower.

6. Let it be understood, accordingly, that there is a higher and a lower
series of plants ; namely : —

PHANEROGAMOUS PLANTS, which come from seed and bear fowers, es-
sentially stamens and pistils, through the co-operation of which seed is
produced. For shortness, these are commonly called PHANEROGAMS, or
Phanogams, or by the equivalent English name of FLOWERING PLANTS.*

CRYPTOGAMOUS PLANTS, or CRYPTOGAMS, come from minute bodies, which
answer to seeds, but are of much simpler structure, and such plants have
not stamens and pistils. Therefore they are called in English FLOWERLESS
PLANTS. Sucli are Ferns, Mosses, Algse or Seaweeds, Fungi, etc. These
sorts have each to be studied separately, for each class or order has a plan
of its own.

7. But Phanerogamous, or Flowering, Plants are all constructed on one
plan, or type. That is, taking almost any ordinary herb, shrub, or tree for
a pattern, it will exemplify the whole series : the parts of one plant answer
to the parts of any other, with only certain differences in particulars. And
the occupation and the delight of the scientific botanist is in tracing out
this common plan, in detecting the likenesses under all the diversities, and
in noting the meaning of these manifold diversities. So the attentive study
of any one plant, from its growth out of the seed to the flowering and
fruiting state and the production of seed like to that from which the plant
grew, would not only give a correct general idea of the structure, growth,
and characteristics of Flowering Plants in general, but also serve as a pat-
tern or standard of comparison. Some plants will serve this purpose of a
pattern much better than others. A proper pattern will be one that is
perfect in the sense of having all the principal parts of a phanerogamous
plant, and simple and regular in having these parts free from complications
or disguises. The common Flax-plant may very well serve this purpose.
Being an annual, it has the advantage of being easily raised and carried
in a short time through its circle of existence, from seedling to fruit and

* The name is sometimes Phanerogamous, sometimes Pheenogamous [Phanero-
gams, or Phten^gams}, terms of the same meaning etymologically ; the former of
preferable form, but the latter shorter. The meaning of sucL terms is explained
in the Glossary.

SECTION II. FLAX AS A PATTEEN PLANT.

8. Growth from the Seed. Phanerogamous plants grow from seed,
and their flowers are destined to the production of seeds. A seed has a
rudimentary plant ready formed in it, — sometimes with the two most
essential parts, i. e. stem and leaf, plainly discernible j sometimes with no
obvious distinction of organs until germination begins. This incipient
plant is called an EMBRYO.

9. In this section the Flax-plant is taken as a specimen, or type, and
the development and history of common plants in general is illustrated by
it. In flax-seed the embryo nearly fills the coats, but not quite. There
is a small deposit of nourishment between the seed-coat and the embryo :
this may for the present be left out of the account. This embryo consists
of a pair of leaves, pressed together face to face, and attached to an ex-
tremely short stem. (Fig. 2-4.) In this rudimentary condition the real
nature of the parts is not at once apparent ; but when the seed grows they
promptly reveal their character, — as the accompanying figures (Fig. 5-7)
show.

10. Before the nature of these parts in the seed was altogether under.
stood, technical names were given to them, which are still in use. These
initial leaves were named COTYLEDONS. The initial stem on which they
stand was called the RADICLE. That was because it gives rise to the first
root ; but, as it is really the beginning of the stem, and because it is the
stem that produces the root and not the root that produces the stem, it is
better to name it the CATJLICLE. Recently it has been named Hypocotyle;
which signifies something below the cotyledons, without pronouncing what
its nature is.

the other cut half away, bringing contained embryo into view. 3. Similar section
of a flax-seed more magnified and divided flatwise? turned round, so that the
stem-end (caulicle) of the embryo is below: the whole broad upper part is the

cotyledons, and the minute plumule between them. i. e. the minute bud on the

[SECTION 2.

11. On committing these seeds to moist and warm soil they soon sprout,
i. e. germinate. The very short stem-part of the embryo is the first to
grow. It lengthens, protrudes its root-end ; this turns downward, if not
already pointing in that direction, and while it is lengthening a root forms
at its point and grows downward into the ground. This root continues to
grow on from its lower end, and thus insinuates itself and
penetrates into the soil. The stem meanwhile is adding

to its length throughout ; it erects itself, and, seeking the
light, brings the seed up out of the ground. The mate-
rials for this growth have been supplied by the cotyledons
or seed-leaves, still in the seed : it was the store of nour-
ishing material they held which gave them their thickish
shape, so unlike that of ordinary leaves. Now, relieved of
a part of this store of food, which has formed the growth by
which they have been raised into the air
and light, they appropriate the remain-
der to their own growth. In enlarging ,
they open and throw off the seed-husk ; *
they expand, diverge into a horizontal
position, turn green, and thus become
a pair of evident leaves, the first foliage
of a tiny plant. This seedling, although
diminutive and most simple, possesses
and puts into use, all the ORGANS of
VEGETATION, namely, root, stem, and
leaves, each in its proper element, — the
root in the soil, the stem rising out of
it, the leaves in the light and open air.
It now draws in moisture and some
food-materials from the soil by its root,

conveys this through the stem into the leaves, where these materials, along
with other crude food which these imbibe from the air, are assimilated into
vegetable matter, i. e. into the material for further growth.

12. Further Growth soon proceeds to the formation of new parts, —
downward in the production of more root, or of branches of the main root,
upward in the development of more stem and leaves. That from which a
stem with its leaves is continued, or a new stem (i. e. branch) originated, is
a BUD. The most conspicuous and familiar buds are those of most shrubs
and trees, bearing buds formed in summer or autumn, to grow the following

leaves (cotyledons) at the other : minute bud (plumule) between these. 6. Same

spring. But every such point for new growth may equally bear the name.
When there is such a bud between the cotyledons in the seed or seedling
it is called the PLUMULE. This is conspicuous enough in a bean (Fig. 29.),
where the young leaf of the new growth looks like a little plume, whence the
name, plumule. In flax-seed this is very minute indeed, but is discernible
with a magnilier, and in the seedling it shows itself distinctly (Fig. 5, 6, 7).

13. As it grows it shapes itself into a second pair of leaves, which of
course rests on a second joint of stem, although in this instance that remains
too short to be well seen. Upon its

summit appears the third pair of
leaves, soon to be raised upon its
proper joint of stem ; the next leaf is
single, and is carried up still further
upon its supporting joint of stem ;
and so on. The root, meanwhile,
continues to grow underground, not
joint after joint, but continuously,
from its lower end ; and commonly
it before long multiplies itself by
branches, which lengthen by the
same continuous growth. But
stems are built up by a succession
of leaf-bearing growths, such as are
strongly marked in a reed or corn-
stalk, and less so in such an herb as
Flax. The word "joint " is ambigu-
ous : it may mean either the portion
between successive leaves, or their
junction, where the leaves are at-
tached. For precision, therefore,
the place where the leaf or leaves
are borne is called a NODE, and the
naked interval between two nodes,
an INTERNODB.

14. In this way a simple stem
with its garniture of leaves is de-
veloped from the seed. But besides

this direct continuation, buds may form and develop into lateral dtems, that
is, into branches, from any node. The proper origin of branches is from
the AXIL of a leaf, i. e. the angle between leaf and stem on the upper side ;
and branches may again branch, so building up the herb, shrub, or tree.
But sooner or later, and without long delay in an annual like Flax, instead
of this continuance of mere vegetation, reproduction is prepared for by

Fio. 8. Up,oer part of Flax-plant in blossom.

15. Blossoming. In Flax the flowers make their appearance at the
end of the stem and branches. The growth, which otherwise might con-
tinue them farther or indefinitely, now takes the form of blossom, and is
subservient to the production of seed.

16. The Flower of Flax consists, first, of five small green leaves,
crowded into a circle : this is the CALYX, or flower-cup. When its sepa-
rate leaves are referred to they are called SEPALS, a name which distin-
guishes them from foliage-leaves on the one hand, and from petals on the
other. Then come five delicate and colored leaves (in the Flax, blue), which
form the COROLLA, and its leaves are PETALS j then a circle of organs, in

9 10

which all likeness to leaves is lost, consisting of slender stalks with a knob
at summit, the STAMENS; and lastly, in the centre, the rounded body,
which becomes a pod, surmounted by five slender or stalk-like bodies.
This, all together, is the PISTIL. The lower part of it, which is to contain the
seeds, is the OVARY ; the slender organs surmounting this are STYLES ; the
knob borne on the apex of each style is a STIGMA. Going back to the sta-
mens, these are of two parts, viz. the stalk, called FILAMENT, and the body
it bears, the ANTHER. Anthers are filled with POLLEN, a powdery sub-
stance made up of minute grains.

17» The pollen shed from the anthers when they open falls upon or is
conveyed to the stigmas ; then the pollen-grains set up a kind of growth (to
be discerned only by aid of a good microscope), which penetrates the style :
this growth takes the form of a thread more delicate than the finest spider's
web, and reaches the bodies which are to become seeds (OVULES they are
called until this change occurs) ; these, touched by this influence, are in-
cited to a new growth within, which becomes an embryo. So, as the ovary
ripens into the seed-pod or capsule (Fig. 1, etc.) containing seeds, each
seed enclosing a rudimentary new plantlet, the round of this vegetable
existence is completed.

SECTION HI. MOKPHOLOGY OP SEEDLINGS.

18. Having obtained a general idea of the growth and parts of a pha-
nerogamous plant from the common Flax of the field, the seeds and seed-
lings of other familiar plants may be taken up, and their variations from the
assumed pattern examined.

19. Germinating Maples are excellent to begin with, the parts being
so much larger than in Flax that a common magnifying glass, although
convenient, is hardly necessary. The only disadvantage is that fresh seeds
are not readily to be had at all seasons.

20. The seeds of Sugar Maple ripen at the end of summer, and germi-
nate In early spring. The em-
bryo fills the whole seed, in

which it is nicely packed ; and
the nature of the parts is ob-
vious even before growth begins.
There is a stemlet (caulicle) and
a pair of long and narrow seed-
leaves (cotyledons), doubled up and coiled, green even in the seed, and in
germination at once unfolding into the first pair of Mage-leaves, though
of shape quite unlike those that follow.

21. Red Maple seeds are ripe and ready to germinate at the beginning of
lummer, and are therefore more convenient for study. The cotyledons are
crumpled in the seed, and not easy to straighten out until they unfold them-
selves in germination. The story of their development into the seedling is
told by the accompanying Fig. 14-20 ; and that of Sugar Maple is closely
similar. No plumule or bud appears in the embryo of these two Maples
until the seed-leaves have nearly attained their full growth and are acting
as foliage-leaves, and until a root is formed below. There is no great store
of nourishment in these thin cotyledons ; so further growth has to wait
until the root and seed-leaves have collected and elaborated sufficient ma-
terial for the formation of the second internode and its pair of leaves,
which lending their help the third pair is more promptly produced, and
so on.

22. Some change in the plan comes with the Silver or Soft White Maple.
(Fig. 21-25). This blossoms in earliest spring, and it drops its large and

a vestige of the habit of Maples in general. Their unusual thickness is due

to the large store of nutritive matter they contain, and this prevents their
developing into actual leaves. Correspondingly, their caulicle does not
lengthen to elevate them above the surface of the soil ; the growth below
the cotyledons is nearly all of root. It is the little plumule or bud between

them which makes the upward growth, and which, being well fed by the
cotyledons, rapidly develops the next pair of leaves and raises them upon
a long internode, and so on. The cotyledons all the while remain below,
in the husk of the fruit and seed, and perish when they have yielded up the
store of food which they contained.

23. So, even in plants so much alike as Maples, there is considerable
difference in the amount of food stored up in the cotyledons by which the
growth is to be made ; and there are corresponding differences in the ger-

mination. The larger the supply to draw upon, the stronger the growth,
and the quicker the formation of root below and of stem and leaves above.
This deposit of food thickens the
cotyledons, and renders them less
and less leaf-like in proportion to
its amount.

24. Examples of Embryos
with thickened Cotyledons.
In the Pumpkin and Squash (Fig.
26, 27), the cotyledons are well
supplied with nourishing matter,
as their sweet taste demonstrates.
Still, they are flat and not very
thick. In germination this store
is promptly utilized in the devel-
opment of the caulicle to twenty or
thirty times its length in the seed,
and to corresponding thickness, in
the formation of a cluster of roots
at its lower end, and the early pro-
duction of the incipient plumule ;
also in their own growth into effi-
cient green leaves. The case of
our common Be-in (Phaseolus vul-
garis, Fig. 28-30) is nearly the
same, except that the cotyledons

are much more gorged ; so that, although carried up into the air and light
upon the lengthening caulicle, and there acquiring a green color, they
never expand into useful leaves. Instead of this, they nourish into rapid
growth the plumule, which is plainly visible in the seed, as a pair of
incipient leaves; and these form the first actual foliage.

25. Very similar is the germination of the Beech (Fig. 31-33), except
that the caulicle lengthens less, hardly raising the cotyledons out of the
ground. Nothing would be gained by elevating them, as they never grow
out into efficient leaves ; but the joint of stem belonging to the plumule
lengthens well, carrying up its pair of real foliage-leaves.

26. It is nearly the same in the Bean of the Old World (Vicia Faba,
here called Horse Bean and Windsor Bean) : the caulicle lengthens very
little, does not undertake to elevate the heavy seed, which is left below or

upon the surface of the soil, the flat but thick cotyledons remaining m it,
and supplying food for the growth of the root below and the plumule
above. In its near relative, the Pea (Fig. 34, 35), this use of cotyledons

for storage only is most completely carried ont. For they are thickened
to the utmost, even into hemispheres ; the caulicle does not lengthen at all ;
merely sends out roots from the lower end, and develops its strong plu-
mule from the upper, the seed remaining unmoved underground. That is,
in technical language, the germination is hypogeeous.

27- There is sufficient nourishment in the cotyledons of a pea to make
a very considerable growth before any actual foliage is required. So it
is the stem-portion of the plumule which is at first conspicuous and strong-
growing. Here, as seen in Fig. 35, its lower nodes bear each a useless
leaf-scale instead of an efficient leaf, and only the later ones bear leaves
fitted for foliage.

28. This hypogaom germination is exemplified on a larger scale by the
Oak (Fig. 36, 37) and Horse-chestnut (Fig. 38, 39); but in these the
downward growth is wholly a stout tap-root. It is not the caulicle ; for

this lengthens hardly any. Indeed, the earliest growth which carries
the very short caulicle out of the shell comes from the formation of foot-
stalks to the cotyledons ; above these develops the strong plumule, below
grows the stout root. The growth is at first entirely, for a long time

mainly, at the expense of the great store of food in the cotyledons. These,
after serving their purpose, decay and fall away.

29. Such thick cotyledons never separate; indeed, they sometimes grow
together by some part of their contiguous faces ; so that the germination

seems to proceed from a solid bulb-like mass.
This is the case in a horse-chestnut.

30. Germinating Embryo supplied by its
own Store of Nourishment, i. e. the store in
the cotyledons. This is so in all the illustrations
thus far, essentially so even in the Flax. This
nourishment was supplied by the mother plant to
the ovule and seed, and thence taken into the
embryo during its growth. Such embryos, filling
f the whole seed, are comparatively large and strong,

and vigorous in germination in proportion to the
amount of their growth while connected with the parent plant.

Some seeds have very little of this deposit, but a comparatively large em-
bryo, with its parts more or less developed and recognizable. In others
this deposit forms the main bulk of the seed, and the embryo is small or
minute, and comparatively rudimentary. The following illustrations exem-
plify these various grades. When an embryo in a seed is thus surrounded
by a white substance, it was natural to liken the latter to the white of an
egg, and the embryo or germ to the yolk. So the matter around or bj
the side of the embryo was called the Albumen,
i. e. the white of the seed. The analogy is not
very good ; and to avoid ambiguity some botan-
ists call it the ENDOSPERM. As that means m
English merely the inwards of a seed, the new
name is little better than the old one ; and, since
we do not change names in botany except
when it cannot be avoided, this name of albu-
men is generally kept up. A seed with such a
deposit is albuminous, one with none is exal-
buminous.

32. The ALBUMEN forms the main bulk of
the seed in wheat, maize, rice, buckwheat, and
the like. It is the floury part of the seed.
Also of the cocoa-nut, of coffee (where it is dense
and hard), etc. ; while in peas, beans, almonds,
and in most edible nuts, the store of food, al-
though essentially the same in nature and in
use, is in the embryo itself, and therefore is not
counted as anything to be separately named.
In both forms this concentrated food for the
germinating plant is food also for man and for
animals.

33. For an albuminous seed with a well-developed embryo, the com-
mon Morning Glory (Ipomoea purpurea, Fig. 40-43) is a convenient exam-
ple, being easy and prompt to grow, and having all the parts well apparent,
The seeds (duly soaked for examination) and the germination should be
sompared with those of Sugar and Red Maple (19-21). The only essen-
tial difference is that here the embryo is surrounded by and crumpled up in
the albumen. This substance, which is pulpy or mucilaginous in fresb
and young seeds, hardens as the seed ripens, but becomes again pulpy in
germination; aud, as it liquifies, the thin cotyledons absorb it by their

whole surface. It supplements the nutritive matter contained in the
embryo. Both together form no large store, but sufficient for establishing
the seedling, with tiny root, stem, and pair of leaves for initiating its
independent growth; which in due time proceeds as in Tig. 44, 45.

34. Smaller embryos, less developed in the seed, are more dependent
upon the extraneous supply of food. The figures 46-53 illustrate fouf

grades in this respect. The smallest, that of the Peony, is still large enough
to be seen with a hand magnifying glass, and even its cotyledons may be
discerned by the aid of a simple stage microscope.

35. The broad cotyledons of Mirabilis, or Four-o'clock (Fig. 52, 53),
with the slender caulicle almost encircle and enclose the floury albumen,
instead of being enclosed in it, as in the other illustrations. Evidently
here the germinating embryo is principally fed by one of the leaf-like coty-
ledons, the other being out of contact with the supply. In the embryo of
Abronia (Fig. 54, 55), a near relative of Mirabilis, there is a singular
modification ; one cotyledon is almost wanting, being reduced to a rudi-
ment, leaving it for the other to do the work. This leads to the question
of the

constructed upon one and the same plan, namely, that of two leaves on a
caulicle or initial stem, — a plan which is obvious even when one cotyledon
becomes very much smaller than the other, as in the rare instance of Abro-
nia (Fig. 54, 55). la other words, the embryos so far examined are all

37. Dicotyledonous, that is, two-cotyledoned. Plants which are thus
similar in the plan of the embryo agree likewise in the leneral structure of

46 48 50 92

their stems, leaves, and blossoms ; and thus form a class, named from their
embryo DICOTYLEDONES, or in English, DICOTYLEDONOUS PLANTS. So long
a name being inconvenient, it may be shortened into DICOTYLS.

38. Polycotyledonous is a name employed for the less usual case in
which there are more than two cotyledons. The Pine is the most familiar
case. This occurs in all Pines, the number of cotyledons varying from three
to twelve ; in Fig. 56, 57 they are six. Note that they are all on the same
level, that is, belong to the same node, so as to form a circle or whorl at the
summit of the caulicle. When there are only three cotyledons, they divide
the space equally, are one third of the circle apart. When only two they
are 180° apart, that is, are opposite.

39. The case of three or more cotyledons, which is constant in Pines
and in some of their relatives (but not in all of them), is occasional among
Dicotyls. And the polycotyledonous is only a variation of the dicotyledonous
type, — a difference in the number of leaves in the whorl ; for a pair is a
whorl reduced to two members. Some suppose that there are really only

two cotyledons even in a Pine-embryo, but these divided or split up con.
genitally so as to imitate a greater number. But as leaves are often in
whorls on ordinary stems, they may be so at the very beginning.

40. Monoootyledorous (meaning with
single cotyledon) is the j lame of the one-coty-

/ledoned sort of embry). This goes along (f\
with peculiarities in stem, leaves, and flowers ; i
which all together asso- ;iate such plants into
a great class, called MONOCOTYLEDONOUS
PLANTS, or, for shortness, MONOCOTYLS. It
means merely that the leaves are alternate
from the very first.

41. In Iris (Fig. 58, 59) the embryo in
the seed is a small cylinder at one end of the
mass of the albumen, with no apparent dis-
tinction of parts. The end which almost
touches the see«{-coat is caulicle; the other
end belongs tc the solitary cotyledon. In

germination the whole lengthen? (but mainly the
cotyledon) only enough to push the proximate
end fairly out of the seed : from this end the root
is formed ; and from a little higher the plumule
later emerges. It would appear, therefore, that
the cotyledon answers to a miaute leaf rolled up,
and that a chink through 'vhich the plumule
grows out is a part of the w rolled edges. The
embryo of Indian Cora shows these parts on a
larger scale and in a more open state (Fig. 66-
68). There, in the seed, the cotyledon remains,
imbibing nourishment from rhe softened albu-
men, and transmitting it to xhe growing root
below and new-forming leaves above.

42. The general plan is the stme in the Onion (Fig. 60-65), but witn
a striking difference. The embryo is long, and coiled in the albumen of the
seed. To ordinary examination it shows no distinction of parts. • But
germination plainly shows that all except the lower end of it is cotyledon.

the cereal grains) it raises the comparatively light seed into the air, the
tip still remaining in the seed and feeding upon the albumen. When
this food is exhausted and the seedling is well es-
tablished in the soil, the upper end decays and the
emptied husk of the seed falss away.

43. In Maize or In-
dian Corn (Fig. 66-70),
the embryo is more de-
veloped in the seed, and
its parts can be made out.
It lies against the starchy
albumen, but is not
enclosed therein. The
larger part of it is the
cotyledon, thickish, its
edges involute, and its
back in contact with the
albumen ; partly enclosed
by it is the well-devel-
oped plumule or bud
which is to grow. For
the cotyledon remains in
the seed to fulfil its office
of imbibing nourishment
from the softened albu-
men, which it conveys to
the growing sprout ; the
part of this sprout which is visible is the first leaf of the plumule rolled up
into a sheath and enclosing the rudiments of the succeeding leaves, at the
base enclosing even the minute caulicle. In germination the first leaf of
the plumule develops only as a sort of sheath, protecting the tender parts
within; the second and the third form the first foliage. The caulicle never
lengthens: the first root, which is formed at its lower end, or from any
part of it, has to break through the enclosing sheath ; and succeeding roots
soon spring from all or any of the nodes of the plumule.

44. Simple-stemmed Plants are thus built up, by the continuous pro-
duction of one leaf-bearing portion of stem from the summit of the preced-
ing one, beginning with the initial stem (or caulicle) in the embryo. Some
Dicotyls and many Monocotyls develop only in this single line of growth (as
to parts above ground) until the flowering state is approached. For some
examples, see Cycas (Fig. 71, front, at the left) ; a tall Yucca or Spanish
Bayonet, and two Cocoa-nut Palms behind ; at the right, a group of Sugar-
canes, and a Banana behind.

BUDS.

SECTION IV. GBOWTH FfiOM BUDS : BRANCHING.

45. Most plants increase the amount of their vegetation by branching,
that is, by producing lateral shoots.

46. Roots branch from any part and usually without definite order.
Stems normally give rise to branches only at definite points, namely, at the
nodes,, and there only from the axils of leaves.

47. Buds (Fig. 72, 73). Every incipient shoot is a Bud (12). A
stem continues its growth by its terminal bud; it branches by the forma-
tion and development of lateral buds. As normal lateral buds occupy the
axils of leaves, they are called axillary buds. As leaves are symmetrically
arranged on the stem, the buds in their axils and the branches into which
axillary buds grow partake of this symmetry.

The most conspicuous buds are the scaly winter-
buds of most shrubs and trees of temperate and
cold climates ; but the name belongs as well to
the forming shoot or branch of any herb.

48. The Terminal Bud, in the most general
sense, may be said to exist in the embryo, — as
cotyledons, or the cotyledons and plumule, — and
to crown each successive growth of the simple
stem so long as the summit is capable of growth.
The whole ascending growth of the Palm, Cy-
cas, and the like (such as in Fig. 71) is from
a terminal bud. Branches, being repetitions of
the main stem and growing in the same way,
are also lengthened by terminal buds. Those of
Horse-chestnut, Hickory, Maples, and such trees,
being the resting buds of winter, are conspicu-
ous by their protective covering of scales.
These bud-scales, as will hereafter be shown,
are themselves a kind of leaves.

49. Axillary Buds were formed on these
annual shoots early in the summer. Occasion-
ally they grow the same season into branches ; at least, some of them are
pretty sure to do so whenever the growing terminal bud at the end of the
shoot is injured or destroyed. Otherwise they may lie dormant until the
following spring. In many trees or shrubs these axillary buds do not
show themselves until spring ; but if searched for, they may be detected,
though of small size, hidden under the bark. Sometimes, although early

formed, they are concealed all summer long under the base of the leaf-stalk,
which is then hollowed out into a sort of inverted cup, like a candle-
extinguisher, to cover them ; as in the Locust, the Yellow-wood, or more
strikingly in the Button- wood or Plane-tree (Fig. 74).

50. The leaf-scars, so conspicuous in Fig. 72, 73, under each axillary
bud, mark the place where the stalk of the subtending leaf was attached
until it fell in autumn.

51. Scaly Buds, which are well represented in Fig. 72, 73, commonly
belong to trees and shrubs of countries in which growth is suspended dur-
ing winter. The scaly coverings protect the tender young parts beneath,
not so much by keeping out the cold, which of course would penetrate the
bud in time, as by shielding the interior from the effects of sudden changes.
There are all gradations between these and

52. Naked Buds, in which these scales are inconspicuous or wanting,
as in most herbs, at least above ground, and most tropical trees and shrubs.
But nearly related plants of the same climate may differ widely in this re-
spect. Rhododendrons have strong and scaly winter-buds ; while in Kalmia
they are naked. One species of Viburnum, the Hobble-bush, has com-
pletely naked buds, what would be a pair of scales developing into the first
leaves in spring; while another (the Snowball) has conspicuous scaly buds.

53. Vigor of Vegetation from strong buds. Large and strong buds,
like those of the Horse-chestnut, Hickory, and the like, contain several
leaves, or pairs of leaves, ready formed, folded and packed away in small
compass, just as the seed-leaves of a strong embryo are packed away in the
seed : they may even contain all the blossoms of the ensuing season, plainly
visible as small buds. And the stems upon which these buds rest are filled
vrith abundant nourishment, which was deposited the summer before in the

FIG. 74. An axillary bud, concealed under the hollowed base of the leafstalk,

SECTION 4.J BUDfiL 29

wood or in the bark. Under the surface of the soil, or on it covered with
the fallen leaves of autumn, similar strong buds of our perennial herbs may
be found; while beneath are thick roots, rootstocks, or tubers, charged
with a great store of nourishment for their use. This explains how it is thai
vegetation from such buds shoots forth so vigorously in the spring of the
year, and clothes the bare and lately frozen surface of the soil, as well as
the naked boughs of trees, very promptly with a covering of fresh green,
and often with brilliant blossoms. Everything was prepared, and even
formed, beforehand : the short joints of stem in the bud have only to
lengthen, and to separate the leaves from each other so that they may un-
fold and grow. Only a small part of the vegetation of the season comes
directly from the seed, and none of the earliest vernal vegetation. This is
all from buds which have lived through the winter.

64. The Arrangement of Branches, being that of axillary buds, answers
to that of the leaves. Now leaves principally are either opposite or alternate.
Leaves are opposite when there are two from the same joint of stem, as in
Maples (Fig. 20), the two being on opposite sides of the stem ; and so the
axillary buds and branches are opposite, as in Fig. 75. Leaves are alter-
nate when there is only one from each joint of stem, as in the Oak, Lime-
tree, Poplar, Button- wood (Fig. 74), Morning-Glory (Fig. 45, — not
counting the seed-leaves, which of course are opposite, there being a pair
of them) ; also in Indian Corn (Fig. 70), and Iris (Fig. 59). Consequently
the axillary buds " are also alternate, as in Hickory (Fig. 73) ; and the
branches they form alternate, — making a different kind of spray from the
other mode, one branch shooting on one side of the stem and the next
on some other. For in the alternate arrangement no leaf is on the same
side of the stem as the one next above or next below it.

55. But the symmetry of branches (unlike that of the leaves) is rarely
complete. This is due to several causes, and most commonly to the

56. Non-development of buds. It never happens that all the buds
grow. If they did, there might be as many branches in any year as there
were leaves the year before. And of those which do begin to grow, a
/arge portion perish, sooner or later, for want of nourishment, or for want
of light, or because those which first begin to grow have an advantage,
which they are apt to keep, taking to themselves the nourishment of the
stem, and starving the weaker buds. In the Horse-chestnut (Fig. 72),
Hickory (Fig. 73), Magnolia, and most other trees with large scaly buds,
the terminal bud is the strongest, and has the advantage in growth ; and
next in strength are the upper axillary buds : while the former continues
the shoot of the last year, some of the latter give rise to branches, and
the rest fail to grow. In the Lilac also (Fig. 75), the uppermost axillary
buds are stronger than the lower ; but the terminal bud rarely appears at
all; in its place the uppermost pair of axillary buds grow, and so each
stem branches every year into two, — making a repeatedly two-forked
ramification, as in Fig. 76.

BUDS.

[SECTION 4,

57. Latent Buds. Axillary buds that do not grow at the proper season,
and especially those which make no appearance externally, may long remain
latent, and at length upon a favorable occasion start into growth, so form-
ing branches apparently out of place
as they are out of time. The new
shoots seen springing directly out
of large stems may sometimes orig-
inate from such latent buds, which
( have preserved their life for years.
But commonly these arise from

58. Adventitious Buds. These
are buds which certain shrubs and
trees produce anywhere on the sur-
face of the wood, especially where
it has been injured. They give ris&
to the slender twigs which often
feather the sides of great branches
of our American Elms. They some-
times form on the root, which natu-
rally is destitute of buds ; they are
even found upon some leaves ; and
they are sure to appear on the
trunks and roots' of Willows, Pop-
lars, and Chestnuts, when these are
wounded or mutilated. Indeed
Osier- Willows are pollarded, or out
off, from time to time, by the culti-
vator, for the purpose of produc-
ing a crop of slender adventitious twigs, suitable for basket-work. Such
branches, being altogether irregular, of course interfere with the natural
symmetry of the tree. Another cause of
irregularity, in certain trees and shrubs,
is the formation of what are called

59. Accessory or Supernumerary
Buds. There are cases where two, three,
or more buds spring from the axil of a
leaf, instead of the single one which is or-
dinarily found there. Sometimes -they are
placed one over the other, as in the Aris-
tolochia or Pipe- Vine, and in the Tartarean Honeysuckle (Fig. 77) ; also
in the Honey-Locust, and in the Walnut and Butternut (Fig. 78), where

the upper supernumerary bud is a good way out of the axil and above the

others. And this is here stronger than the others, and grows into a

branch which is considerably out of the axil, while the lower and smaller

ones commonly do not grow at all. In other cases

three buds stand side by side in the axil, as in the

Hawthorn, and the Red Maple (Fig. 79.) If these

were all to grow into branches, they would stifle each

other. But some of them are commonly flower-buds :

in the Red Maple, only the middle one is a leaf-bud,

and it does not grow until after those on each side of

it have expanded the blossoms they contain.

60. Sorts of Buds. It may be useful to enumerate
the kinds of buds which have been described or men-
tioned. They are

Terminal, when they occupy the summit of (or ter*
inmate) a stem,

Lateral, when they are borne on the side of a stem ;
of which the regular kind is the

Axillary, situated in the axil of a leaf. These are

Accessory or Supernumerary, when they are in v
addition to the normal solitary bud; and these are
Collateral, when side by side ; Superposed, when one
above another;

Extra-axillary, when they appear above the axil, as
some do when superposed, and as occasionally is the
case when single. »

Naked buds ; those which have no protecting scales.

Scaly buds ; those which have protecting scales,
which are altered leaves or bases of leaves.

Leaf-buds, contain or give rise to leaves, and develop into a leafy shoot.

Flower-buds, contain or consist of blossoms, and no leaves.

Mixed buds, contain both leaves and blossoms.

61. Definite annual Growth from winter buds is marked in most of
the shoots from strong buds, such as those of the Horse-chestnut and
Hickory (Fig. 72, 73). Such a bud generally contains, already formed in
miniature, all or a great part of the leaves and joints of stem it is to pro-
duce, makes its whole growth in length in the course of a few weeks, or
sometimes even in a few days, and then forms and ripens its buds for the
next year's similar growth.

62. Indefinite annual Growth, on the other hand, is well marked in
such trees or shrubs as the Honey-Locust, Sumac, and in sterile shoots of

FIG. 78. Butternut branch, with accessory buds, the uppermost above the axil.

FIG. 79. Red-Maple branch, with accessory buds placed side by side. The an-
nular lines toward the base in this and in Fig. 72 are scars of the bud-scales, and

the Hose, Blackberry, and Raspberry. That is, these shoots are apt to
grow all summer long, until stopped by the frosts of autumn or some other
cause. Consequently they form and ripen no terminal bud protected by
scales, and the upper axillary buds are produced so late in the season that
they have no time to mature, nor has their wood time to solidify and ripen.
Such stems therefore commonly die back from the top in winter, or at
least all their upper buds are small and feeble ; so the growth of the suc-
ceeding year takes place mainly from the lower axillary buds, which are
more mature.

63. Deliquescent and Excurrent Growth. In the former case, and
wherever axillary buds take the lead, there is, of course, no single main
stem, continued year after year in a direct line, but the trunk is soon lost

in the branches. Trees so formed commonly have rounded or spreading
tops. Of such trees with deliquescent stems, — that is, with the trunk
dissolved, as it were, into the successively divided branches, — the common
American Elm (Fig. 80) is a good illustration.

64. On the other hand, the main stem of Firs and Spruces, unless de-
stroyed by some injury, is carried on in a direct line throughout the whole
growth of the tree, by the development year after year of a terminal bud :
this forms a single, uninterrupted shaft, — an excurrent trunk, which can-
not be confounded with the branches that proceed from it. Of such spiry
or spire-shaped trees, the Firs or Spruces are characteristic and familiar
examples There are all gradations between the two modes.

65. It is a property of stems to produce roots. Stems do not spring
from roots in ordinary cases, as is generally thought, but roots from stems.
When perennial herbs arise from the ground, as they do at spring-time,
they rise from subterranean stems.

66. The Primary Root is a downward growth from the root-end o*
the caulicle, that is, of the initial stem of the embryo (Fig. 5-7, 81). H
it goes on to grow it makes a main or tap-root, as in Fig. 37, etc. Some
plants keep this main root throughout

their whole life, and send off only
small side branches ; as in the Carrot
and Radish : and in various trees, like
the Oak, it takes the lead of the
side-branches for several years, unless
accidentally injured, as a strong tap-
root. But commonly the main root
divides off very soon, and is lost in the
branches. Multiple primary roots now
and then occur, as in the seedling of
Pumpkin (Fig. 27), where a cluster
is formed even at the first, from the
root-end of the caulicle.

67. Secondary Roots are those
which arise from other parts of the
stem. Any part of the stem may

produce them, but they most readily come from the nodes. As a general
rule they naturally spring, or may be made to spring, from almost any
young stem, when placed in favorable circumstances, —that is, when
placed in the soil, or otherwise supplied with moisture and screened from
the light. For the special tendency of the root is to avoid the light, seek
moisture, and therefore to bury itself in the soil. Propagation by division,
which is so common and so very important in cultivation, depends upon
the proclivity of stems to strike root. Stems or branches which remain
underground give out roots as freely as roots themselves give off branches.
Stems which creep on the ground most commonly root at the joints ; so
will most branches when bent to the ground, as in propagation by layer-
ing; and propagation by cuttings equally depends upon the tendency of the
cut end of a shoot to produce roots. Thus, a piece of a plant which has
stem and leaves, either developed or in the bud, may be made to produce
roots, and so become an independent plant.

68. Contrast between Stem and Root Stems are ascending axes;
roots are descending axes. Stems grow by the successive development of
internodes (13), one after another, each leaf-bearing
at its summit (or node) ; so that it is of the essen-
tial nature of a stem to bear leaves. Roots bear no
leaves, are not distinguishable into nodes and inter-
nodes, but grow on continuously from the lower
end. They commonly branch freely, but not from
any fixed points nor in definite order.

69. Although roots
generally do not give
rise to stems, and there-
fore do not propagate
the plant, exceptions are
not uncommon. For as
stems may produce ad-
ventitious buds, so also
may roots. The roots of
the Sweet Potato among
herbs, and of the Osage
Orange among trees
freely produce adveuti-
' tious buds, developing
into leafy shoots ; and
so these plants are
propagated by root-cut-
tings. But most growths
of subterranean origin
which pass for roots are forms of stems, the common Potato for example.

70. Roots of ordinary kinds and uses may be roughly classed mi® fibrous
and fleshy.

71. Fibrous Boots, such as those of Indian Corn (Fig. 70), of most
annuals, and of many perennials, serve only for absorption : these are
slender or thread-like. Fine roots of this kind, and the fine branches which
most roots send out are called ROOTLETS.

72. The whole surface of a root absorbs moisture from the soil while fresh
and new ; and the newer roots and rootlets are, the more freely do they im-
bibe. Accordingly, as long as the plant grows above ground, and expands
fresh foliage, from which moisture largely escapes into the air, so long it
continues to extend and multiply its roots in the soil beneath, renewing and
increasing the fresh surface for absorbing moisture, in proportion to the
demand from above. And when growth ceases above ground, and the
leaves die and fall, or no longer act, then the roots generally stop growing,

FIG. 83-85. Forms of tap-root.

SECTION 5.]

35

and their soft arid tender tips harden. From this period, therefore, until
growth begins anew the next spring, is the best time for transplanting ;
especially for trees and shrubs.

73. The absorbing surface of young roots is much increased by the for-
mation, near their tips, of ROOT-HAIRS (Fig. 81f 82), which are delicate

tubular outgrowths from the surface, through the delicate walls of which
moisture is promptly imbibed.

74. Fleshy Roots are those in which the root becomes a storehouse of
nourishment. Typical roots of this kind are those of such biennials as the
turnip and carrot ; in which the food created in the first season's vege-
tation is accumulated, to be expended the next season in a vigorous growth
and a rapid development of flowers, fruit, and seed. By the time the seed
is matured the exhausted root dies, and with it the whole plant.

75. Fleshy roots may be single or multiple. The single root of the
commoner biennials is the primary root, or tap-root, which begins to
thicken in the seedling. Names are given to its shapes, such as

Conical, when it thickens most at the crown, or where it joins the stem,
and tapers regularly downwards to a point, as in the Parsnip and Carrot
(Fig. 84);

Turnip-shaped or napiform, when greatly thickened above, but abruptly
becoming slender below ; as the Turnip (Fig. 83) ; and

FIG. 86. Sweet-Potato plant forming thickened roots. Some in the middle are
just beginning to thicken; one at the left has grown more; one at the right is still
larger.

[SECTION 5.

Spindle-shaped, or Fusiform, when thickest in the middle and tapering to
both ends ; as the common Radish (Fig, 85).

76. These examples are of primary roots. It will be seen that turnips,
carrots, and the like, are not pure root throughout ; lor the caulicle, from
the lower end of which the root grew, partakes of the thickening, perhaps
also some joints of stem above : so the bud-bearing and growing top is
stem.

77. A fine example of secondary roots (67), some of which remain fibrous
for absorption, while a few thicken, ami store up food for the next season's
growth, is furnished by the Sweet Potato (Fig. 86). As stated above,
these are used for propagation by cuttings; for any part will produce ad-
ventitious buds and shoots. The Dahlia produces fascicled (i. e, clustered)
fusiform roots of the same kind, at the base of the stem (Fig. 87) : but
these, like most roots, do not produce adventitious buds. The buds by
which Dahlias are propagated belong to the surviving base of the stem

78. Anomalous Roots, as they may be sailed, are those which subserve
other uses than absorption, food-storing, and fixing the plant to the soil.

Aerial Roots, i. e. those that strike from stems in the open air, are
common in moist and warm
climates, as in the Mangrove
which reaches the coast of
Florida, the Banyan, and, less
strikingly, in some herbace-
ous plants, such as Sugar
Cane, and even in Indian
Corn. Such roots reach the
ground at length, or tend to
do so.

Aerial Rootlets are abun-
dantly produced by many
climbing plants, such as the
Ivy, Poison Ivy, Trumpet
Creeper, etc., springing from
the side of stems, which they
fasten to trunks of trees,
walls, or other supports.
These are used by the plant
fir climbing.

79. Epiphytes, or Air-
Plants (Fig. 88), are called by the former name because commonly growing

upon the trunks or limbs of other plants ; by the latter because, having no
connection with the soil, they must derive their sustenance from the air
only. They have aerial roots, which do not reach the ground, but are used
to fix the plant to the surface upon which the plant grows : they also take
a part in absorbing moisture from the air.

80. Parasitic Plants, of which there are various kinds, strike their
roots, or what answer to roots, into the tissue of foster plants, or form at-
tachments with their surface, so as to prey upon their juices. Of this sort
is the Mistletoe, the seed of which germinates on the bough where it
falls or is left by birds ; and the forming root penetrates the bark and en.
grafts itself into the wood, to which it becomes united as firmly as a natural
branch to its parent stem ; and indeed the parasite lives just as if it were
a branch of the tree it grows and feeds on. A most common parasitic herb
is the Dodder; which abouuds in low grounds in summer, and coils its
long and slender, leafless, yellowish stems — resembling tangled threads of
yarn — round and round the stalks of other plants ; wherever they touch
piercing the bark with minute and very short rootlets iu the form of
suckers, which draw out the nourishing juices of the plants laid hold of.
Other parasitic plants, like the Beech-drops and Pine-sap, fasten their roots
under ground upon the roots of neighboring plants, and rob them of theii
juices.

81. Some plants are partly parasitic ; while most of their roots act in
the ordinary way, others make suckers at their tips which grow last to the

roots of other plants and rob them of nourishment. Some of our species of
Gerardia do this (Fig. 89).

82. There are phanerogamous plants, like Monotropa or Indian Pipe,
the roots of which feed mainly on decaying vegetable matter in the soil.
These are SAPROPHYTES, and they imitate Mushrooms and other Fungi in
their mode of life.

83. Duration of Roots, etc. Roots are said to be either annual, bien-
nial, or perennial. As respects the first and second, these terms may be
applied either to the root or to the plant.

84-. Annuals, as the name denotes, live for only one year, generally for

only a part of the year. They are of course herbs ; they spring from the
seed, blossom, mature their fruit and seed, and then die, root and all. An-
nuals of our temperate climates with severe winters start from the seed in
spring, and perish at or before autumn. Where the winter is a moist and
growing season and the summer is dry, winter annuals prevail ; their seeds
germinate under autumn or winter rains, grow more or less during winter,
blossom, fructify, and perish in the following spring or summer. Annuals
are fibrous-rooted.

85. Biennials, of which the Turnip, Beet, and Carrot are familiar ex-
amples, grow the first season without blossoming, usually thicken their
roots, laying up in them a stock of nourishment, are quiescent during the
winter, bnt shoot vigorously, blossom, and seed the next spring or summer,
mainly at the expense of the food stored up, and then die completely.
Annuals and biennials flower only once; hence they have been called
Monocarpic (that is, once-fruiting) plants.

86. Perennials live and blossom year after year. A perennial herb, in
a temperate or cooler climate, usually dies down to the ground at the end
of the season's growth. But subterranean portions of stem, charged with
buds, survive to renew the development. Shrubs and trees are of course
perennial ; even the stems and branches above ground live on and grow
year after year.

87. There are all gradations between annuals and biennials, and between
these and perennials, as also between herbs and shrubs ; and the distinc-
tion between shrubs and trees is quite arbitrary. There are perennial herbs
and even shrubs of warm climates which are annuals when raised in a cli-
mate which has a winter, — being destroyed by frost. The Castor-oil plant
is an example. There are perennial herbs of which only small portions
survive, as off-shoots, or, in the Potato, as tubers, etc.

SECTION VI. STEMS.

88. The Stem is the axis of the plant, the part which bears all the
other organs. Branches are secondary stems, that is, stems growing out of
stems. The stem at the very beginning produces roots, in most plants a
single root from the base of the embryo-stem, or caulicle. As this root
becomes a descending axis, so the stem, which grows in the opposite direc-
tion is called the ascending axis. Rising out of the soil, the stem bears
leaves; and leaf-bearing is the particular characteristic of the stem. But
there are forms of stems that remain underground, or make a part of their
growth there. These do not bear leaves, in the common sense; yet they
bear rudiments of leaves, or what answers to leaves, although not in the
form of foliage. The so-called stemless or acaulescent plants are those
which bear no obvious stem (caulis) above ground, but only flower-stalks,
and the like.

SECTION 6.) STEMS. 39

89. Stems above ground, through differences fa duratvn, texture, and
size, form herbs, shrubs, trees, etc., or in other terms are

Herbaceous, dying down to the ground every year, or after blossoming.

Suffrutescent) slightly woody below, there surviving from year to year.

Suffruticose or Frutescent, when low stems are decidedly woody below,
but herbaceous above.

Fruticose or Shrubby, woody, living from year to year, and of considerable
size, — uot, however, more than three or four times the height of a man.

Arborescent, when tree-like in appearance or mode of growth, or ap»
proaching a tree in size.

Arboreous, when forming a proper tree-trunk.

90. As to direction taken in growing, stems may, instead of growing
upright or erect, be

Diffuse, that is, loosely spreading in all directions.
Declined, when turned or bending over to one side.
Decumbent, reclining on the ground, as if too weak to stand.
Ass-urgent or Ascending, rising obliquely upwards.
Procumbent or Prostrate, lying flat on the ground from the first.
Creeping or Repent, prostrate on or just beneath the ground, and striking
root, as does the White Clover, the Partridge-berry, etc.

Climbing or Scandent, ascending by clinging to other objects for support,
whether by tendrils, as do the Pea, Grape- Vine, and Passion-flower and
Virginia Creeper (Fig. 92, 93) ; by their twisting leaf-stalks, as the Virgin's
Bower; or by rootlets, like the Ivy, Poison Ivy, and Trumpet Creeper.

Twining or Voluble, when coiling spirally around other stems or
supports; like the Morning-Glory (Tig. 90) and the Hop.

91. Certain kinds
, of stems or branches,
appropriated to sp&
cial uses, have re-
ceived distinct substantive names ; such as the following :

92. A Culm, or straw-stem, such as that of Grasses
and Sedges.

93. A Caudex is the old name for such a peculiar
trunk as a Palm-stem ; it is also used for an upright and
thick rootstock.

94. A Sucker is a branch rising from stems under
ground. Such are produced abundantly by the Rose,
Raspberry, and other plants said to multiply "by the
root." If we uncover them, we see at once the great
difference between these subterranean branches and real
roots. They are only creeping branches under ground.

Remarking how the upright shoots from these branches become separate

plants, simply by the dying off of the connecting under-ground stems, the
gardener expedites the result by cutting them through with his spade.
That is, he propagates the plant " by division."

95. A Stolon is a branch from above ground, which reclines or becomes
prostrate and strikes root (usually from the nodes) wherever it rests on the
soil. Thence it may send up a vigorous shoot, which has roots of its own,
and becomes an independent plant when the connecting part dies, as it
does after a while. The Currant and the Gooseberry naturally multiply in
this way, as well as by suckers (which are the same thing, only the connect-
ing part is concealed under ground). Stolons must .have suggested the
operation of layering by bending down and covering with soil branches
which do not naturally make stolons ; and after they have taken root, as
they almost always will, the gardener cuts through the connecting stem,
and so converts a rooting branch into a separate plant.

96. An Offset is a short stolon, or sucker, with a crown of leaves at the
end, as in the Houseleek (Fig.

91), which propagates abundantly
in this way.

97. A Runner, of which the
Strawberry presents the most fa-
miliar and characteristic example,
is a long and slender, tendril-like
stolon, or branch from next the
ground, destitute of conspicuous
leaves. Each runner of the Straw-
berry, after having grown to its full

length, strikes root from the tip, which fixes it to the ground, then forms
a bud there, which develops into a tuft of leaves, and so gives rise to a new
plant, which sends out new runners to act in the same way. In this
manner a single Strawberry plant will spread over a large space, or produce
a great number of plants, in the course of the summer, all connected at
first by the slender runners ; but these die in the following winter, if not
before, and leave the plants as so many separate individuals.

98. Tendrils are branches of a very slender sort, like runners, not destined
like them for propagation, and therefore always destitute of buds or leaves,
being intended only for climbing. Simple tendrils are such as those of
Passion-flowers (Fig. 92). Compound or branching tendrils are borne by
the Cucumber and Pumpkin, by the Grape-Vine, Virginia Creeper, etc.

99. A tendril commonly grows straight and outstretched until it reaches
some neighboring support, such as a stem, when its apex hooks around it
to secure a hold ; then the whole tendril shortens itself by coiling up
spirally, and so draws the shoot of the growing plant nearer to the sup-
porting object. But the tendrils of the Virginia Creeper (Ampelopsis, Fig.

Fio. 91. Houseleek (Sempervivum), with offsets

41

93), as also the shorter ones of the Japanese species, effect the object differ-
ently, namely, by expanding the tips of the tendrils into a flat disk, with
an adhesive face. This is applied to the supporting object, and it adheres

firmly ; then a
shortening of
the tendril and

its branches by coiling brings up the growing
shoot close to the support. This is an adapta-
tion for climbing mural rocks or walls, or the
trunks of trees, to which ordinary tendrils are
unable to cling. The Ivy and Poison Ivy attain
the same result by means of aerial rootlets (78).

100. Some tendrils are leaves or parts of
leaves, as those of the Pea (Fig. 35). The na-
ture of the tendril is known by its position. A
tendril from the axil of a leaf, like that of Pas-
sion-flowers (Fig. 92) is of course a stem, i. e.
a branch. So is one which terminates a stem,
as in the Grape-Vine.

101. Spines or Thorns (Fig. 95, 96) are
commonly stunted and hardened branches
or tips of stems or branches, as are those of
Hawthorn, Honey-Locust, etc. In the Pear
and Sloe all gradations occur between spines
and spine-like (spinescent) branches. Spinel

iaay be reduced and indurated leaves; as in the Barberry, where theii
nature is revealed by their situation, underneath an axillary bud. But

prickles, such as those of Blackberry and Roses, are only excrescences
of the bark, and not branches.

102. Equally strange forms of
stems are characteristic of the
Cactus family (Fig. 111). These
may be better understood by com-
parison with

103. Subterranean Stems
and Branches. These are very
numerous and various ; but they
are commonly overlooked, or else
are confounded with roots. From
their situation they are out of or-
dinary sight ; but they will well
repay examination. For the veg-
etation that is carried on under
ground is hardly less varied or
important than that above ground.
All their forms may be referred to
four principal kinds : namely, the
Rhizoma (Rhizome) or Rootstock,
the Tuber, the Corm or solid bulb,
and the true Bulb.

10*. The Rootstock, or Rhi-
zoma, in its simplest form, is
merely a creeping stem or branch
growing beneath the surface of the soil, or partly covered by it. Of
this kind are the so-called creeping, running, or scaly roots, such as those

by which the Mint (Fig. 97), the Couch-grass, or Quick-grass, and man\
other plants, spread so rapidly and widely, — " by the root," as it is said.
That these are really stems, and not roots, is evident from the way in which

they grow ; from their consisting of a succession of joints ; and from the
leaves which they bear on each node, in the form of small scales, just like
the lowest ones on the upright stem next the ground. They also pro-
duce buds in the axils of these scales, showing the scales to be leaves ;
whereas real roots bear neither leaves nor axillary buds. Placed as
they are in the damp and dark soil, such stems naturally produce roots,
just as the creeping stem does where it lies on the surface of the
ground.

105. It is easy to see why plants with these running rootstocks take
such rapid and wide possession of the soil, and why they are so hard to
get rid of. They are always perennials ; the subterranean shoots live over
the first winter, if not longer, and are provided with vigorous buds at every
joint. Some of these buds grow in spring into upright stems, bearing
foliage, to elaborate nourishment, and at length produce blossoms for re-
production by seed ; while many others, fed by nour-
ishment supplied from above, form a new generation

of subterranean shoots ; and this is repeated over and
over in the course of the season or in succeeding
years. Meanwhile, as the subterranean shoots in-
crease in number, the older ones, connecting the suc-
cessive growths, die off year by year, liberating the
already rooted side-branches as so many separate plants ; and so on indefi-
nitely. Cutting these running rootstocks into pieces, therefore, by the hoe
or the plough, far from destroying the plant, only accelerates the propaga
tion ; it converts one many -branched plant into a great number of separate
individuals. Cutting into pieces only multiplies the pest ; for each piece
' (Fig. 98) is already a plantlet, with its roots and with a bud in the axil of
its scale-like leaf (either latent or apparent), and with prepared nourishment
enough to develop this bud into a leafy stem ; and so a single plant is all the
more speedily converted into a multitude. Whereas, when the subterra-
nean parts are only roots, cutting away the stem completely, destroys
the plant, except in the rather rare cases where the root freely produces
adventitious buds.

106. Rootstocks are more commonly thickened by the storing up of
considerable nourishing matter in their tissue. The common species of
Iris (Fig. 164) in the gardens have stout rootstocks, which are only partly
covered by the soil, and which bear foliage-leaves instead of mere scales,
closely covering the upper part, while the lower produces roots. As the
leaves die, year by year, and decay, a scar left in the form of a ring marks
the place where each leaf was attached, that is, marks so many nodes,
separated by very short internodes.

107. Some rootstocks are marked with large round scars of a different

sort, like those of the Solomon's Seal (Fig. 99), which gave this name to
the plant, from their looking somewhat like the impression of a seal upon

wax. Here the
rootstock sends up
every spring an
herbaceous stalk or
stem, which bears
the foliage aud
flowers, and dies
in autumn. The
teal is the circular

scar left by the death and separation of the base of the stout stalk from the
living rootstock. As but one of these is formed each year, they mark
the limits of a year's growth. The bud at the end of the rootstock in the
6gure (which was taken in summer) will grow the next .spring into the
stalk of the season, which, dying in autumn, will
leave a similar scar, while another bud will be formed
farther on, crowning the ever-advancing summit or
growing end of the stem.

108. A? each year's growth of stem makes its
own roots, it soon becomes independent of the older
parts. A.nd after a certain age, a portion annually
dies off behind, about as fast as it increases at the
growing eud, death following life with equal aud cer-
tain step, with only a narrow interval. In vigorous
plants of Solomon's Seal or Iris, the living rootstock
is several inches or a foot in length ; while in the
short rootstock of Trillium or Birthroot (Fig. 100)
life is reduced to a narrower span.

109. An upright or short rootstock, like this of Trillium, is commonly
called a GAUDEX (93) ; or when more shortened and thickened it would
become a corm.

110. A Tuber may be onderstood to be a portion of a rootstock thick-
ened, and with buds (eyes) on the sides. Of course, there are all grada
tions between a tuber and a rootstock. Helianthus tuberosus, the so-called
Jerusalem Artichoke (Fig. 101), and the common Potato, are typical aud
familiar examples of the tuber. The stalks by which the tubers are at-
tached to the parent stem are at once seen to be different from the roots,
both in appearance and manner of growth. The scales on the tubers are the
rudiments of leaves ; the eyes are the buds in their axils. The Potato-plant

has three forms of branches : 1. Those that bear ordinary leaves expanded
in the air, to digest what they gather from it and what the roots gather
from the soil, and convert it into nourishment. 2. After a while a second
set of branches at the summit of the plant bear flowers, which form fruit
and seed out of a portion of the nour-
ishment which the leaves have pre-
pared. 3. But a larger part of this
nourishment, while in a liquid state,
is carried down the stem, into a third
sort of branches under ground, and
accumulated in the form of starch at
their extremities,
which become tu-
bers, or deposito-
ries of prepared
solid food, — just
as in the Turnip,
Carrot, and Dah-
lia (Fig. 83-87),
it is deposited in

"Jie root. The use of the store of food is obvious enough. In the autumn
the whole plant dies, except the seeds (if it formed them) and the tubers ;
and the latter are left disconnected in the ground. Just as that small
portion of nourishing matter which is deposited in the seed feeds the
embryo when it germinates, so the much larger portion deposited in the
tuber nourishes its buds, or eyes, when they likewise grow, the next
spring, into new plants. And the great supply enables them to shoot
with a greater vigor at the beginning, and to produce a greater amount
of vegetation than the seedling plant could do in the same space of time ;
which vegetation in turn may prepare and store up, in the course of a
few weeks or months, the largest quantity of solid nourishing material,
in a form most available for food. Taking advantage of this, man has
transported the Potato from the cool Andes of Chili to other cool climates,
and makes it yield him a copious supply of food, especially important in
countries where the season is too short, or the summer's heat too little, for
profitably cultivating the principal grain-plants.

111. The Conn or Solid Bulb, like that of Cyclamen (Fig. 103), and
of Indian Turnip (Fig. 104), is a very short and thick fleshy subterranean
stem, often broader than high. It sends off roots from its lower end, or rather
face, leaves and stalks from its upper. The corm of Cyclamen goes on to
enlarge and to produce a succession of flowers and leaves year after year.

[SECTION 6.

That of Indian Turnip is formed one year and is consumed the next. Fig.
104 represents it in early summer, having below the corm of last year, from
which the roots have fallen. It is partly consumed by the growth of the

stem for the season, and the
corm of the year is forming
at base of the stem above
the line of roots.

112. The corm of Crocus
(Fig. 105, 106), like that
of its relative Gladiolus, is
also reproduced annually,
the new ones forming upon
the summit and sides of the old. Such a corm is like a tuber in bud-
ding from the sides, i. e. from the axils of leaves ; but these leaves, instead
of being small scales, are the sheathing bases of fo-
liage-leaves which covered the surface. It resem-
bles a true bulb in having these sheaths or broad
scales ; but in the corm or solid bulb, this solid part
or stem makes up the principal bulk.

113. The Bulb, strictly so-called, is a stem like
a reduced corm as to its solid part (or plate) ;
while the main body consists of thickened scales,
which are leaves or leaf-bases. These are like bud-
scales ; so that in fact a bulb is a bud with fleshy
scales on an exceedingly short stem. Compare a
White Lily bulb (Fig. 107) with the strong scaly
buds of the Hickory and Horse-chestnut (Fig. 72
and 73), and the resemblance will appear. In
corms, as in tubers and rootstocks, the store of
food for future growth is deposited in the stem ;
while in the bulb, the greater part is deposited in
the bases of the leaves, changing them into thick
scales, which closely overlap or enclose one another.

114. A Scaly Bulb (like that of the Lily, Fig. 107, 108) is one in which
the scales are thick but comparatively narrow.

115. A Tunicated or Coated Bulb is one in which the scales enwrap
each other, forming concentric coats or layers, as in Hyacinth and Onion.

116. Bulblets are very small bulbs growing out of larger ones ; or
small bulbs produced above ground on some plants, as in the axils of the
leaves of the bulbiferous Lilies of the gardens (Fig. 110), and often in the
flower-clusters of the Leek and Onion. They are plainly
buds with thickened scales. They never grow into
branches, but detach themselves when full grown, fall to
the ground, and take root there to form new plants.

117« Consolidated Vegetation. An ordinary herb,
shrub, or tree is evidently constructed on the plan
developing an extensive surface. In fleshy rootstocks,

I

tubers, corms, and bulbs, the more enduring portion of the plant is con-
centrated, and reduced for the time of struggle (as against drought, heat,
or cold) to a small amount of
exposed surface, and this mostly
sheltered in the soil. There are
many similar consolidated forms
which are not subterranean.
Thus plants like the Houseleek
(Fig. 91) imitate a bulb. Among
Cactuses the columnar species of
Cereus (Fig. Ill, 6), may be lik-
ened to rootstocks. A green rind serves the purpose of foliage ; but the
surface is as nothing compared with an ordinary leafy plant of the same
bulk. Compare, for instance, the largest Cactus known, the Giant Cereus
of the Gila River (Fig. Ill, in the background), which rises to the height
of fifty or sixty feet, with a common leafy tree of the same height, such
as that in Fig. 89, and estimate how vastly greater, even without the foli-
age, the surface of the latter is than that of the former. Compare, in the

same view, an Opuntia or Prickly-Pear Cactus, its stem and branches
formed of a succession of thick and flattened joints (Fig. Ill, a), which
may be likened to tubers, or an Epipliyllum (^), having short and flat
joints, with an ordinary leafy shrub or herb of equal size. And finally,
in Melon-Cactuses, Echinocactus (c), or other globose forms (which may
be likened to permanent corms), with their globular or bulb-like shapes,
we have plants in the compactest shape; their spherical figure being such
as to expose the least possible amount of substance to the air. These are
adaptations to climates which are very dry, either throughout or for a part
of the year. Similarly, bulbous and corm-bearing plants, and the like, are
examples of a form of vegetation which in the growing season may expand a
large surface to the air and light, while during the period of rest the living
vegetable is reduced to a globe, or solid form of the least possible surface;
and this protected by its outer coats of dead and dry scales, as well as by
its situation under ground. Such are also adapted to a season of drought.
They largely belong to countries which have a long hot season of little or
no rain, when, their stalks and foliage above and their roots beneath early
perishing, the plants rest securely in their compact bulbs, filled with
nourishment and retaining their moisture with great tenacity, until the
rainy season comes round. Then they shoot forth leaves and flowers with
wonderful rapidity, and what was perhaps a desert of arid sand becomes
green with foliage and gay with blossoms, almost in a day.

SECTION 7.) ORDINARY LEAVES. 45

SECTION VII. LEAVES.

118. STEMS bear leaves, at definite points (nodes, 13) ; and these are
produced in a great variety of forms, and subserve various uses. The
commonest kind of leaf, which therefore may be taken as the type or
pattern, is an expanded green body, by means of which the plant exposes
to the air and light the matters which it imbibes, exhales certain portions,
and assimilates the residue into vegetable matter for its nourishment and
growth.

119. But the fact is already familiar (10-30) that leaves occur under
other forms and serve for other uses, — for the storage of food already
assimilated, as in thickened seed-leaves and bulb-scales ; for covering, as in
bud-scales ; and still other uses are to be pointed out. Indeed, sometimes
they are of no service to the plant, being reduced to mere scales or rudi-
ments, such as those on the rootstocks of Peppermint (Eig. 97) or the
tubers of Jerusalem Artichoke (Fig. 101). These may be said to be of
service only to the botanist, in explaining to him the plan upon which a
plant is constructed.

120. Accordingly, just as a rootstock, or a tuber, or a tendril is a kind
of stem, so a bud-scale, or a bulb-scale, or a cotyledon, or a petal of a flower,
is a kind of leaf. Even in respect to ordinary leaves, it is natural to use
the word either in a wider or in a narrower sense ; as when in one sense
we say that a leaf consists of blade and petiole or leaf-stalk, and in another
sense say that a leaf is petioled, or that the leaf of Hepatica is three-lobed.
The connection should make it plain whether by leaf we mean leaf-blade
only, or the blade with any other parts it may have. And the student will
readily understand that by leaf in its largest or morphological sense, the
botanist means the organ which occupies the place of a leaf, whatever be
its form or its function.

§ 1. LEAVES AS FOLIAGE.

121. This is tautological; for foliage is simply leaves: but it is very
convenient to speak of typical leaves, or those which serve the plant for
assimilation, as foliage-leaves, or ordinary leaves. These may first be
considered.

122. The Parts of a Leaf. The ordinary leaf, complete in its parts,
consists of blade, foot-stalk, or petiole, and a pair of stipules.

123. Eirst the BLADE or LAMINA, which is the essential part of ordinary
leaves, that is, of such as serve the purpose of foliage. In structure it con-
sists of a softer part, the green pulp, called parenchyma, which is traversed
and supported by a fibrous frame, the parts of which are called ribs or veins,
on account of a certain likeness in arrangement to the veins of animals',

50

LEAVES.

[SECTION T.

The whole surface is covered by a transparent skin, the Epidermis, not
unlike that which covers the surface of all fresh shoots.

124. Note that the leaf-blade expands horizontally, — that is, normally
presents its faces one to the sky, the other to the ground, or when the
leaf is erect the upper face looks toward the stem that bears it, the lower
face away from it. Whenever this is not the case there is something to be
explained.

125. The framework consists of wood, — a fibrous and tough material
which runs from the stem through the leaf-stalk, when there is one, in the

form of parallel threads or bundles of fibres ;
and in the blade these spread out in a hori-
zontal direction, to form the ribs and veins
of the leaf. The stout main branches of
the framework are called the Ribs. When
there is only one, as in Fig. 112, 114, or a
middle one decidedly larger than the rest,
it is called the Midrib. The smaller divi-
sions are termed Feins; and their still
smaller subdivisions, Veinlets. The latter
subdivide again and again, until they be-
come so fine that they are invisible to the
naked eye. The fibres of which they are
composed are hollow; forming tubes by
which the sap is brought into the leaves
and carried to every part.

126. Venation is the name of the mode
of veining, that is, of the way in whicli the
veins are distributed in the blade. This is
tf two principal kinds ; namely, the parallel-veined, and the netted-veined.

127. In Netted-veined (also called Reticulated) leaves, the veins branch
off from the main rib or ribs, divide into finer and finer veinlets, and the
branches unite with each other to form meshes of network. That is, they
anastomose, as anatomists say of the veins and arteries of the body. The
Quince-leaf, in Fig. 112, shows this kind of veining in a leaf witli a single
rib. The Maple, Basswood, Plane or Buttonwood (Fig. 74) show it in
leaves of several ribs.

128. In parallel-veined leaves, the whole framework consists of slender
ribs or veins, which run parallel with each other, or nearly so, from the
base to the point of the leaf, — not dividing and subdividing, nor forming-
meshes, except by minute cross-veinlets. The leaf of any grass, or that of
the Lily of the Valley (Fig. 113) will furnish a good illustration. Such
parallel veins Linnaeus called Nerves, and parallel-veined leaves are still
eommonlv called nerved leaves, while those of the other kind are said to be

51

veined, — terms which it is convenient to use, although these "nerves"
and " veins " are all the same thing, and have no likeness to the nerves and
little to the veins of animals.

129. Netted-veined leaves belong to plants which have a pair of seed-
leaves or cotyledons, such as the Maple (Fig. 20, 24,), Beech (Fig. 33), and

tne fifce ; white parallel-veined or nerved leaves belong to plants with one
cotyledon or true seed-leaf; such as the Iris (Fig. 59), and Indian Corn
(Fig. 70). So chat a mere glance at the leaves generally tells what the
structure of the embryo is, and refers the plant to one or the other of these
two grand classes, — which is a great convenience. For when plants differ
from each other in some one important respect, they usually differ corres-
pondingly in other respects also.

130. Parallel- veined leaves are of two sorts, — one kind, and the com-
monest, having the ribs or nerves all running from the base to the point of
the leaf, as in the examples already given ; while in another kind they run
from a midrib to the margin, as in the common Pickerel-weed of our
ponds, in the Banana, in Calla (Fig. 114), and many similar plants of
warm climates.

131. Netted-veined leaves are also of two sorts, as in the examples al-
ready referred to. In one case the veins all rise from a single rib (the
midrib), as in Fig. 112, 116-127. Such leaves are called Feather-veined
or Penni-veined, i. e. Pinnately-veined ; both terms meaning the same thing,
namely, that the veins are arranged on the sides of the rib like the plume
of a feather on each side of the shaft.

[SECTION 7.

132. In the other case (as in Fig. 74, 129-132), the veins branch off
from three, five, seven, or nine ribs, which spread from the top of the leaf-
stalk, and run through the blade like the toes of a web-footed bird. Hence
these are said to be Palmately or Digitately veined, or (since the ribs di-
verge like rays from a centre) Radiate-veined.

133. Since the general outline of leaves accords with the frame-work or
skeleton, it is plain that feather-veined (or penni-veined} leaves will incline-
to elongated shapes, or at least to be longer than broad ; while in radiate-
veined leaves more rounded forms are to be expected. A glance at the
following figures shows this.

134. Forms of Leaves as to General Outline. It is necessary to give
names to the principal shapes, and to define them rather precisely, since
they afford easy marks for distinguishing species. The same terms are used

for all other flattened parts as well, such as petals ; so that they make up a
great part of the descriptive language of Botany. It will be a good exer-
cise for young students to look up leaves answering to these names and
definitions. Beginning with the narrower and proceeding to the broadest
forms, a leaf is said to be

Linear (Pig. 115), when narrow, several times longer than wide, and of
the same breadth throughout.

Lanceolate, or Lance-shaped, when conspicuously longer than wide, and
tapering upwards (Fig. 116), or both upwards and downwards.

Oblong (Fig. 117), when nearly twice or thrice as long as broad.

Elliptical (Fig. 118) is oblong with a flowing outline, the two ends alike
in width.

Oval is the same as broadly elliptical, or elliptical with the breadth con-
siderably more than half the length.

Ovate (Fig. 119), when the outline is like a section of a hen's egg
lengthwise, the broader end downward.

Orbicular, or Rotund (Fig. 132), circular in outline, or nearly so.

135. A leaf which tapers toward the base instead of toward the apex
may be

Oblanceolate (Fig. 121) when of the lance-shaped form, only more tapering
toward the base than in the opposite direction.

Spatulate (Fig. 122) when more rounded above, but tapering thence to a
narrow base, like an old-fashioned spatula.

FIG. 115-120. A series of shapes of feather-veined leaves.

53

Obovate (Fig. 123) or inversely ovate, that is, ovate with the narrower

end down.

Cuneate or Cuneiform, that is,
Wedge-shaped (Fig. 124), broad
above and tapering by nearly
straight lines to an acute angle at
the base.

136. As to the Base, its shape
characterizes several forms, such as
Cordate or Heart-shaped (Fig.
120, 129), when a leaf of an ovate form, or something like it, has the out-
line of its rounded base
turned in (forming a
notch or sinus) where the
stalk is attached.

Reniform, or Kidney-
shaped (Fig. 131), like
the last, only rounder and
broader than long.

Auriculate, or Eared,
4 having a pair of small
126 126 127 and blunt projections, or

ears, at the base, as in one species of Magnolia (Fig. 126).

Sagittate, narrow-shaped,
where such ears are acute
and turned downwards,
while the main body of the
blade tapers upwards to a
point, as in the common
Sagittaria or Arrow-head,
and in the Arrow-leaved
Polygonum ^Fig. 125).
Hastate, or Halberd-shaped,
when such lobes at the base j
point outwards, giving the
shape of the halberd of the
olden time, as in another
Polygonum (Fig. 127).

Peltate, or Shield-shaped (Fig. 132), is the name applied to a curious
modification of the leaf, commonly of a rounded form, where the footstalk
is attached to the lower surface, instead of the base, and therefore is natu.

rally likened to a shield borne by the outstretched arm. The common
Watershield, the Neluinbium, and the White Water-lily, and also the Man-
drake, exhibit this sort of leaf. On comparing the shield-shaped leaf of
the common Marsh Pennywort (Fig. 132) with that of another common
species (Fig. 130), it is at once seen that a shield-shaped leaf is like a
kidney-shaped (Fig. 130, 131) or other rounded leaf, with the margins at
the base brought together and united.

137. As to the Apex, the following terms express the principal varia-
tions : —

Acuminate, Pointed, or Taper-pointed, when the summit is more or less
prolonged into a narrowed or tapering point; as in Fig. 133.

Acute, ending in an acute angle or not prolonged point ; Fig. 134.

Obtuse, with a blunt or rounded apex ; as in Fig. 135, etc.

Truncate, with the end as if cut off square ; as in Fig. 136.

Uetme, with rounded summit slightly indented, forming a very shallow
notch, as in Fig. 137.

Emarginate, or Notched, indented at the end more decidedly; as in
Fig. 138.

Obcordate, that is, inversely heart-shaped, where an obovate leaf is more
deeply notched at the end (Fig. 139), as in White Clover and Wood-sorrel ;
so as to resemble a cordate leaf inverted.

Cuspidate, tipped with a sharp and rigid point ; as in Fig. 140.

Mucronate, abruptly tipped with a small and short point, like a mere
projection of the midrib ; as in Fig. 141.

Aristate, Awn-pointed, and Bristle-pointed, are terms used when this
mucronate point is extended into a longer bristle-form or slender appen-
dage.

The first six of these terms can be applied to the lower as well as to the
upper end of a leaf or other organ. The others belong to the apex only.

140 141

138. As to degree and nature of Division, there is first of all the dif-
ference between

Simple Leaves, those in which the blade is of one piece, however much
it may be cut up, and

Compound Leaves, those in which the blade consists of two or more sep-
arate pieces, upon a common leaf-stalk or support. Yet between these two
kinds every intermediate gradation is to be met with.

139. As to Particular Outlines of Simple Leaves (and the same
applies to their separate parts), they are

Entire, when their general outline is completely filled out, so that the
margin is an even line, without teeth or notches.

Serrate, or Saw-toothed, when the margin only is cut into sharp teeth,
like those of a saw, and pointing forwards : as in Fig. 142.

Dentate, or Toothed,
when such teeth point
outwards, instead of
forwards ; as in Fig
143.

Crenate, or Scal-
loped, when the teeth
are broad and round- I
ed ; as in Fig. 144. \

Repand, Undulate, \
or Wavy, when the \ -
margin of the leaf \\
forms a wavy line, 1
bending slightly in-
wards and outwards in succession; as in Fig. 145.

Sinuate, when the margin is more strongly sinuous or turned inwards
and outwards ; as in Fig. 146.

Incised, Cut, or Jagged, when the margin is cut into sharp, deep, and
irregular teeth or incisions ; as in Fig. 147-

Lobed, when deeply cut. Then the pieces are in a general way called
LOBES. The number of the lobes is briefly expressed by the phrase two-
lobed, three~lobed,five-lobed, many-lobed, etc., as the case may be.

140. When the depth and character of the lobiug needs to be more par-
ticularly specified, the following terms are employed, viz. : —

Lobed, in a special sense, when the incisions do not extend deeper than
about half-way between the margin and the centre of the blade, if so far,
and are more or less rounded ; as in the leaves of the Post-Oak, Fig. 148,
and the Hepatica, Fig. 152.

Cleft, when the incisions extend half way down or more, and especially
when they are sharp ; as in Fig. 149, 153. And the phrases two-cleft, or,
in the Latin form, bifid, three-cleft or trifid, four-cleft or quadrifid, five-
cleft or quinquefid, etc., or many-cleft, in the Latin form, mnltifid, — express
the number of the Segments, or portions.

Parted, when the incisions are still deeper, but yet do not quite reach
to the midrib or the base of the blade; as in Fig. 150, 154. And
the terms two-parted, three-parted, etc., express the numfcer of such
divisions.

Divided, when the incisions extend quite to the midrib, as in the lower
part of Fig. 151, or to the leaf-stalk, as in Fig. 155 ; which really makes the

FIG. 142-147. Kinds of margin of leaves.

[SECTION 7

leaf compound. Here, using the Latin form, the leaf is said to be bisected,
trisected (Eig. 155), etc., according to the number of the divisions.

141. The Mode of Loblng or Division corresponds to that of the
veining, whether pinnately veined or palmately veined. In tne former the
notches or incisions, or sinuse*, coming between the principal veins or ribs
are directed toward the midrib : in the latter they are directed toward the
apex of the petiole ; as the figures show.

142. So degree and mode of division may be tersely expressed in brief
phrases. Thus, in the four upper figures of pinnately veined leaves, the
first is said to be pinnately lobed (in the special sense), the second pinnately
cleft (or pinnatifid in Latin form), the third pinnately parted, the fourth
pinnately divided, or pinnatisected.

143. Correspondingly in the lower row, of palmately veined leaves, the
first is palmately lobed, the second palmately cleft, the third palmately
parted, the fourth palmately divided. Or, in other language of the same
meaning (but now less commonly employed), they are said to be digitately
lobed, cleft, parted, or divided.

144. The number of the divisions or lobes may come into the phrase.
Thus in the four last named figures the leaves are respectively palmately

three-lobcd, firee-cleft (or trtyd), three-parted, three-divided, or better (in
Latin form), trisected. And so for higher numbers, 2iSjive-lobed,five-ckft,

etc., up to many-lobed, many-cleft or multifid, etc. The same mode of ex-

-parted, etc.

145. The divisions, lobes, etc., may themselves be entire (without teeth
or notches), or serrate, or otherwise toothed or incised; or lobed, cleft,
parted, etc. : in the latter cases making twice pinnatifid, twice palmately or
pinnately lobed,, parted, or divided leaves, etc. From these illustrations
one will perceive how the botanist, in two or three words, may describe
any one of the almost endlessly diversified shapes of leaves, so as to give a
clear and definite idea of it.

146. Compound Leaves. A compound leaf is one which has its blade
in entirely separate parts, each usually with a stalklet of its own; and the
stalklet is often jointed (or articulated} with the main leaf-stalk, just as this

is jointed with the stem. When this is the case, there is no doubt that
the leaf is compound. But when the pieces have no stalklets, and are not
jointed with the main leaf-stalk, it may be considered either as a divided
simple leaf, or a compound leaf, according to the circumstances. This is
a matter of names where all intermediate forms may be expected.

147. While the pieces or projecting parts of a simple leaf-blade are
called Lobes, or in deeply cut leaves, etc., Segments, or Divisions, the sep-
arate pieces or blades of a compound leaf are called LEAFLETS.

148. Compound leaves are of two principal kinds, namely, the Pinnate
and the Palmate; answering to the two modes of veining in reticulated
^caves. and to the two sorts of lobed or divided leaves (141).

140. Pinnate leaves are those in which the leaflets are arranged on the
sides of a main leaf-stalk : as in Fig. 156-158. They answer to the

Fio. 156-158. Pinnate leaves, the first with an odd leaflet (odd-pinnate)*, the
second with a tendril in place of uppermost leaflets ; the third abruptly pinnate.

feather-veined (i. e. pinnately-veined) simple leaf; as will be seen at once
on comparing the forms. The leaflets of the former answer to the lobes or
divisions of the latter ; and the continuation of the petiole, along which the
leaflets are arranged, answers to the midrib of the simple leaf.

150. Three sorts of pinnate leaves are here given. Fig. 156 is pinnate
with an odd or end leaflet, as in the Common Locust and the Ash. Pig.
157 is pinnate with a tendril at the end, in place of the odd leaflet, as in
the Vetches and the Pea. Tig. 158 is evenly or abruptly pinnate, as in the
Honey-Locust.

151. Palmate (also named Digitate) leaves are those in which the leaf-

lets are all borne on the tip of the" leaf,
stalk, as in the Lupine, the Common
Clover, the Virginia Creeper (Fig. 93),
and the Horse-chestnut and Buckeye
(Fig. 159). They evidently answer to
the radiate-veined or palmately -veined
simple, leaf. That is, the Clover-leaf of
three leaflets is the same as a palmately
, three-ribbed leaf cut into three separate
leaflets. And such a simple five-lobed
leaf as that of the Sugar-Maple, if
more cut, so as to separate the parts,

would produce a palmate leaf of five leaflets, like that of the Horse-chestnut

or Buckeye.

152. Either sort of compound leaf may have any number of leaflets ; yet
palmate leaves cannot well have a great many, since they are all crowded
together on the end of the main leaf-stalk. Some Lupines have nine or
eleven j the Horse-chestnut has seven, the Sweet Buckeye more commonly
five, the Clover three. A pinnate leaf often has only seven or five leaflets,
or only three, as in Beans of the genus Phaseolus, etc. ; in some rarer cases
only fesro; in the Orange and Lemon and also in the common Barberry
there is only one ! The joint at the place where the leaflet is united with
the petiole distinguishes this last case from a simple leaf. In other specie*
of these genera the lateral leaflets also are present.

153. The leaflets of a compound leaf may be either entire (as in Fig.
126-128), or serrate, or lobed, cleft, parted, etc. ; in fact, may present all
the variations of simple leaves, and the same terms equally apply to them.

154. When the division is carried so far as to separate what would be
one leaflet into two, three, or several, the leaf becomes doubly or twice
compound, either pinnately or palmately, as the case may be. For example,
while the clustered leaves of the Honey-Locust are simply pinnate, that is,
mce pinnate, those on new shoots are bipinnate, or twice pinnate, as in
Fig. 160. When these leaflets are again divided in the same way, the leaf

. 159. Palmate (or digitate) leaf of five leaflets of the Sweet Buckeye,

becomes thrice pinnate, or tripinnate, as in many Acacias. The first divi-
sions are called Pinnae ; the others, Pinnules ; and the last, or little blades
themselves, Leaflets.

155. So the palmate leaf, if again
compounded in the same way, be-
comes twice palmate, or, as we say
when the d'visions are in threes,
twice ternate (in Latin form biter-
nate) ; if a third time compounded,
thrice ternate or triternate. But
if the division goes still further,
or if the degree is variable, we
simply say that the leaf is decom-
pound; either palmately or pin-
nately decompound, as the case
may be. Thus, Fig. 161 repre-
sents a four times ternately com-
pound (in other words a ternately
decompound] leaf of a common
Meadow Rue.

156. When the botanist, in de-
scribing leaves, wishes to express
the number of the leaflets, he
may use terms like these : —

Unifoliolate, for a compound
leaf of a single leaflet ; from the
Latin urntm, one, and foliolvm,
leaflet.

Bifoliolate, of two leaflets, from the Latin bis, twice, vn.<\.foliolum, leaflet.
Trifoliolate (or ternats), of three leaf-
lets, as the Clover ; and so on.

Palmately bifoliolate, tnfoliolate,
quadrifoliate, plurifoliolate (of several
leaflets), etc. : or else

Pinnately bi-, tri-, quadri-, or pluri-
foliolate (that is, of two, fciiree, four,
! five, or several leaflets), as the case
may be: these are terse ways of de-
noting in single phrases both the num-
ber of leaflets and the kind of com-
161 pounding.

157. Of foliage-leaves having certain peculiarities in structure, the
following may be noted: —

158. Perfoliate Leav««, In these the stem that bears them seems to
run through the blade of the leaf, more or less above its base. A commoD

Bellwort (Uvularia perfohata, Fig,
162) is a familiar illustration. The
lower and earlier leaves show it
distinctly. Later, the plant is apt
to produce some leaves merely
clasping the stem by the sessile
and heart-shaped base, and the
latest may be merely sessile. So
the series explains the peculiarity :
in the formation of the leaf the
bases, meeting around the stem, grow together there.

159. Connate-perfoliate. Such are the upper leaves of true Honey-
suckles. Here (Fig. 163) of the opposite and sessile leaves, some pairs,
especially the uppermost, in the course of their formation unite around the
stem, which thus seems to run through the disk formed by their union.

160. Equitant Leaves While ordinary leaves spread horizontally, and
present one face to the sky and the other to the earth, there are some that
present their tip to the sky, and their faces right and left to the horizon.
Among these are the equitant leaves of the Iris or Flower-de-Luce. In-
spection shows that each leaf was formed as it folded together lengthwise,

so that what would be the upper surface is within, and all grown together,
except next the bottom, where each leaf covers the next younger one. It
was from their straddling over each other, like a man on horseback (as is
seen in the cross-section, Fig. 165), that Linnaeus, with his lively fancy,
called these Equitant leaves.

161. Leaves with no distinction of Petiole and Blade. The leaves
of Iris just mentioned show oue form of this. The flat but narrow leaves
of Jonquils, Daffodils, and the cylindrical leaf of Onions

are other instances. Needle-shaped leaves, like those of
the Pine, Larch, and Spruce, and the awl-shaped as well >
as the scale-shaped leaves of Junipers, Red Cedar, and
Arbor- Vitae (Fig. 166), are examples.

162. Phyllodia. Sometimes an expanded petiole takes
the place of the blade; as in numerous New Holland
Acacias, some of which are now common in greenhouses.
Such counterfeit blades are called phyllodia, — meaning
leaf-like bodies. They may be known from true blades
by their standing edgewise, their margins being directed
upwards and downwards ; while in true blades the faces
look upwards and downwards; excepting in equitant
leaves, as already explained.

163. Falsely Vertical Leaves. These are apparent
exceptions to the rule, the blade standing edgewise in-
stead of flatwise to the stem ; but this position comes

I by a twist of the stalk or the base of the

blade. Such leaves present the two
faces about equally to the light. The
Compass-plant (Silphium laciniatum) is
an example. So also the leaves of Bolto*
nia, of Wild Lettuce, and of a vast nun>
ber of Australian Myrtaceous shrubs
and trees, which much resemble the
phyllodia of the Acacias of the same
country. They are familiar in Calliste-
mon, the Bottle-brush Flower, and in
Eucalyptus. But in the latter the
leaves of the young tree have the nor
mal structure and position.

164. Cladophylla, meaning branch-
leaves. The foliage of Ruscus (the Butcher's Broom of Europe) and of
Myrsiphyllum of South Africa (cultivated for decoration under the false

name of Smilax) is peculiar and puzzling. If these blades (Fig. 167, 168)

are really leaves, they are most anomalous in occupying the axil of another
leaf, reduced to a little scale. Yet they have an upper and lower face, as
leaves should, although they soon twist, so as to stand more or less edge-
wise. If they are branches which have assumed exactly the form and
office of leaves, they are equally extraordinary in not making any further
development. But in Ruscus, flowers are borne on one face, in the axil
of a little scale : and this would seem to settle that they are branches. In
Asparagus just the same things as to position are thread-shaped and
branch-like.

§ 2. LEAVES OP SPECIAL CONFORMATION AND USB.

165. Leaves for Storage. A leaf may at the same time serve botb
ordinary and special uses. Thus in those leaves of Lilies, such as the
common White Lily, which spring from the bulb, the upper and green part

serves for foliage
and elaborates
nourishment, while
the thickened por-
tion or bud-scale
beneath serves for
the storage of this
nourishment. The
thread -shaped leaf
of the Onion ful-
fils the same office,
and the nourishing
matter it prepares
is deposited in
its sheathing base,
forming one of the
concentric layers of
the onion. When

these layers, so thick and succulent, have given up their store to the grow-
ing parts within, they are left as thin and dry husks. In a Houseleek,
an Aloe or an Agave, the green color of the surface of the fleshy leaf indi-
cates that it is doing ihe work of foliage ; the deeper-seated white por-
tion within is the storehouse of the nourishment which the green surface
has elaborated. So, also, the seed-leaves or cotyledons are commonly used
for storage. Some, as in one of the Maples, the Pea, Horse-chestnut,
Oak, etc., are for nothing else. Others, as in Beech and in our common

Beans, give faint indications of service as foliage also, chiefly in Tain. Still
others, as iu the Pumpkin and Flax, having served for storage, develop
into the first efficient foliage. Compare
11, 22-30, and the accompanying figures.

flowers remain until

166. Leaves as Bud-Scales serve to
protect the forming parts within. Hav-
ing fulfilled this purpose they commonly
fall off when the shoot develops and
foliage-leaves appear. Occasionally, as
in Pig. 170, there is a transition of bud-
scales to leaves, which reveals the nature
of the former. The Lilac also shows a
gradation from bud-scale to simple leaf.
In Cornus florida (the Flowering Dog-
wood), the four bud-scales which through
the winter protect the head of forming
and then the base of each grows out into

a large and very showy petal-like leaf; the original dry scale is apparent
in the notch at the apex.

167. Leaves as Spines occur in several plants. A familiar instance is
that of the common Barberry (Fig. 171). In almost any summer shoot,
most of the gradations may be seen between the ordinary leaves, with
sharp bristly teeth, and leaves which are reduced to a branching spine or
thorn. The fact that the spines of the Barberry produce a leaf-bud in
their axil also proves them to be leaves.

168. Leaves for Climbing are various in adaptation. True foliage-
leaves serve this purpose ; as in Gloriosa, where the attenuated tip of a sim-
ple leaf (otherwise like that of a Lily) hooks around a supporting object ;
or in Solanum jasminoides of the gardens (Fig. 172), and in Maurandia,
etc., where the leaf-stalk coils round and clings to a support ; or in the
compound leaves of Clematis and of Adlumia, in which both the leaflets
and their stalks hook or coil around the support.

169. Or in a compound leaf, as in the Pea and most Vetches, and in
Coba3a, while the lower leaflets serve for foliage, some of the uppermost
are developed as tendrils for climbing (Fig. 167). In the common Pea this
is so with all but one or two pairs of leaflets.

170. In one European Vetch, the leaflets are wanting and the whole
petiole is a tendril, while the stipules become the only foliage (Fig. 173).

171. Leaves as Pitchers, or hollow tubes, are familiar in the common
Pitcher-plant or Side-saddle Flower (Sarracenia, Fig. 174) of our bogs.
These pitchers are generally half full of water, in which flies and other in-
sects are drowned, often in such numbers as to make a rich manure for the
plant. More curious are some of the southern species of Sarracenia, which
seem to be specially adapted to the capture and destruction of flies and
•other insects.

172. The leaf of Nepenthes (Fig. 175) combines three structures and
uses. The expanded part below is foliage : this tapers into a tendril for

climbing ; and this bears a pitcher with a lid. Insects are caught, and per-
haps digested, in the pitcher.

173. Leaves as Fly-traps. Insects are
caught in another way, and more expertly,
by the most extraordinary of all the plants
of this country, the Dionaa or Venus's Fly-
trap, which grows in the sandy bogs around
Wilmington, North Carolina. Here (Fig.
176) each leaf bears at its summit an appen- j
dage which opens and shuts, in shape some- '
thing like a steel-trap, and operating much
like one. For when open, no sooner does
a fly alight on its surface, and brush against
any one of the two or three bristles that grow
there, than the trap suddenly closes, captur-
ing the intruder. If the fly escapes, the trap
soon slowly opens, and is ready for another
capture. When retained, the insect is after
a time moistened by a secretion from mi-
nute glands of the inner suiface, and is
digested. In the various species of Drosora or Sundew, insects are caught

The use of such adaptations and operations may be explained in another
place.

$8. STIPULES.

174. A leaf complete in its parts consists of blade, leaf-stalk or petiole^
and a pair of stipules. But most leaves have either fugacious or minute
stipules or none at all; many have no petiole (the blade being sessile or
stalkless) ; some have no clear distinction of blade and petiole ; and many
of these, such as those of the Onion and
all phyllodia (166), consist Oi petiole only
175. The base of the petiole is apt to
be broadened and flattened, sometimes
into thin margins, sometimes into a sheath
which embraces the stem at the point of
attachment.

176. Stipules are such appendages, either wholly or partly separated
from the petiole. When quite separate they are said to ^ free, as in Fig.
112. When attached to the base of the petiole, as in the Rose and in

Clover (Fig. 177), they are adnate. When the two stipules 'unite and
sheathe the stem above the insertion, as in Polygonum (Fig. 178), this
sheath is called an Ocrea, from its likeness to a greave or leggin.

177- In Grasses, when the sheathing base of the leaf may answer to
petiole, the summit of the sheath commonly projects as a thin and short
membrane, like an ocrea : this is called a LIGULA or LIGULE.

178. When stipules are green and leaf-like they act as so much foliage.
In the Pea they make up no small part of the actual foliage. In a related
pknt (Lathyrus Aphaca, Fig. 173), they make the whole of it, the remainder
of the leaf being tendril.

179. In many trees the stipules are the bud-scales, as in the Beech, and
very conspicuously in the Fig-tree, Tulip-tree, and Magnolia (Fig. 179).
These fall off as the leaves unfold.

180. The stipules are spines or prickles in Locust and several other
Leguminous trees and shrubs ; they are tendrils in Smilax or Greenbrier

| 4. THE ARRANGEMENT OP LEAVES.

181. Phyllotaxy, meaning leaf-arrangement, is the study of the position
o* leaves, or parts answering to leaves, upon the stem.

182. The technical name for the attachment of leaves to the stem is

the insertion. Leaves (as already noticed, 54) are inserted in three modes.
They are

Alternate (Fig. 181), that is, one after another, or in other words, with
only a single leaf to each node ;

FIG. 181. Alternate leaves, in Linden, Lime-tree, or BasswocxJ.
FIG. 182. Opposite leaves, ID Red Maple.

LEAVES,

[SECTION 7.

Opposite (Fig. 182), when there is a pair to each node, the two leaves in
this case being always on opposite sides of the stem ;

Whorled or Verticillate (Fig. 183) when there are more than two leaves
on a node, in whicu case they divide the circle
equally between them, forming a Verticel or whorl.
When there are three leaves in the whorl, the
leaves are one third of the circumference apart ;
when four, one quarter, and so on. So the plan of
opposite leaves, which is very common, is merely
that of whorled leaves, with the fewest leaves to the
whorl, namely, two.

183. In both modes and in all their modifica-
tions, the arrangement is such as to distribute the
leaves systematically and in a way to give them a
good exposure to the light.

The so-

184. No two or more leaves ever grow from the same point.
called Fascicled or Clustered leaves are
the leaves of a branch the nodes of
which are very close, just as they are
in the bud, so keeping the leaves in a
cluster. This is evident in the Larch
(Fig. 184), in which examination shows
each cluster to be made up of nume-
rous leaves crowded on a spur or short
axis. In spring there are only such
clusters ; but in summer some of them
lengthen into ordinary shoots with scat-
tered alternate leaves. So, likewise,
each cluster of two or three needle-
shaped leaves in Pitch Pines (as in Fig. 185), or of five leaves
in White Pine, answers to a similar extremely short branch,
springing from the axil of a thin and slender scale, which
represents a leaf of the main shoot. For Pines produce two
kinds of leaves, — 1. primary, the proper leaves of the shoots,
not as foliage, but in the shape of delicate scales in spring,
which soon fall away; and 2. secondary, the fascicled leaves,
from buds in the axils of the former, and these form the
actual foliage.

185. Phyllotaxy of Alternate Leaves. Alternate leaves are distrib-
uted along the stem iu an order which is uniform for each species. The
arrangement in all its modifications is said to be spiral, because, if we
draw a line from the insertion (i. e. the point of attachment) of one leaf to
that of the next, and so on, this line will wind spirally around the stem as
it rises, and in the same species will always bear the same number of leaves
for each turn round the stem. That is, any two successive leaves will
always be separated from each other by an equal portion of the circum-
ference of the stem. The distance in height between any two leaves may
vary greatly, even on the same shoot, for that depends upon the length of
the internodes, or spaces between the leaves ; but the distance as measured
around the circumference (in other words, the Angular Divergence, or angle
formed by any two successive leaves) is uniformly the same.

186. Two-ranked. The greatest possible di-
vergence is, of course, where the second leaf stands
on exactly the opposite side of the stem from the
first, the third on the side opposite the second, and
therefore over the first, and the fourth over the
second. This brings all the leaves into two ranks,
one on one side of the stem and one on the other,
and is therefore called the Two-ranked arrangement.
It occurs in all Grasses, — in Indian Corn, for in-
stance ; also, in the Basswood (Fig. 181). This
is the simplest of all arrangements, and the one
which most widely distributes successive leaves, but
which therefore gives the fewest vertical ranks.
Next is the

187. Three-ranked arrangement, — that of all
Sedges, and of White Hellebore. Here the second
leaf is placed one third of the way round the stem,
the third leaf two thirds of the way round, the fourth
leaf accordingly directly over the first, the fifth over
the second, and so on. That is, three leaves occur
in each turn round the stem, and they are separated
from each other by one third of the circumference.
(Fig. 186, 187.)

188. Five-ranked is the next in the series, and

the most common. It is seen in the Apple (Fig. 188), Cherry, Poplar,
and the greater number of trees and shrubs. In this case the line traced
from leaf to leaf will pass twice round the stem before it reaches a leaf

situated directly over any below (Fig. 189). Here the sixth leaf is over
the first ; the leaves stand in five perpendicular ranks, with equal angular
distance from each other; and this distance between any two successive
leaves is just two fifths of the circumference of the stem.

189. The five-ranked arrangement is expressed by the fraction f . This

fraction denotes the divergence of Ig9

the successive leaves, i. e. the an-
gle they form with each other : the
* numerator also expresses the num-
ber of turns made round the stem
by the spiral line in completing
one cycle or set of leaves, namely, * d
•; two ; and the denominator gives
the number of leaves in each cy-
cle, or the number of perpendic-
ular ranks, namely, five. In the
same way the fraction J stands for
the two-ranked mode, and J for
the three-ranked : and so these
different sorts are expressed by

ibe series of fractions J, J, f . Other cases follow in

the same numerical progression, the next being the

190. Eight-ranked arrangement. In this the ninth /
leaf stands over the first, and three turns are made i
around the stem to reach it; so it is expressed by
the fraction f . This is seen in the Holly, and in the
common Plantain. Then comes the

191. Thirteen-ranked arrangement, in which the

fourteenth leaf is over the first, after five turns around the stem. The
common Houseleek (Fig. 191) is a good example.

192. The series so far, then, is £, J, f , f , ^ ; the numerator and the
denominator of each fraction being those of the two next preceding ones
added together. At this rate the next higher should be ^r, then £f , and
so on ; and in fact just such cases are met with, and (commonly) no others.
These higher sorts are found in the Pine Family, both in the leaves and
the cones and in many other plants with small and crowded leaves. But
in those the number of the ranks, or of leaves in each cycle, can .only rarely

be made out by direct inspection. They may be indirectly ascertained, how-
ever, by studying the secondary spirals, as they are called, which usually
become conspicuous, at least two series of them, one
turning to the right and one to the left, as shown in
Fig. 191. For an account of the way in which the
character of the phyllotaxy may be deduced from the
secondary spirals, see Structural Botany, Chapter IV.
193. Phyllotaxy of Opposite and whorled Leaves.
This is simple and comparatively uniform. The leaves
of each pair or whorl are placed over the intervals
between those of the preceding, and therefore under
the intervals of the pair or whorl next above. The
whorls or pairs alternate or cross each other, usually
at right angles, that is, they decussate. Opposite
leaves, that is, whorls of two leaves only, are far com-
moner than whorls of three or four or more members.
This arrangement in successive decussating pairs gives
an advantageous distribution on the stem in four verti-
cal ranks. Whorls of three give six vertical ranks,
and so on. Note that in descriptive botany leaves in
whorls of two are simply called opposite leaves ; and
that the term verticillate or whorled, is employed only
for cases of more than two, unless the latter number
is specified.

194. Vernation or Praefoliation, the disposition
of the leaf-blades in the bud, comprises two things ; 1st,
the way in which each separate leaf is folded, coiled,
or packed up in the bud; and 3d, the arrangement
of the leaves in the bud with respect to one another.
The latter of course depends very much upon the

phyllotaxy, i. e. thfe position and order of the leaves upon the stem. The
same terms are used for it as for the arrangement of the leaves of the
flower in the flower-bud. See, therefore, " ^Estivation, or Prafloration."

195. As to each leaf separately, it is sometimes straight and open in
vernation, but more commonly it is either bent, folded, or rolled up. When
the upper part is bent down upon the lower, as the young blade in the
Tulip-tree is bent upon the leafstalk, it is said to be Inflexed or Reclined in
vernation. When folded by the midrib so that the two halves are placed
face to face, it is Conduplicate (Fig. 193), as in the Magnolia, the Cherry,
and the Oak. When folded back and forth like the plaits of a fan, it is

SECTION VIII. FLOWERS.

196. Flowers are for the production of seed (16). Stems and branches,
which for a time put forth leaves for vegetation, may at length put forth
flowers for reproduction.

f 1. POSITION AND ARRANGEMENT OP FLOWEKS, OR INFLOR-
ESCENCE.

197. Flower-buds appear just where leaf -buds appear ; that is, they are
either terminal or axillary (47-49). Morphologically, flowers answer to
shoots or branches, and their parts to leaves.

198. In the same species the flowers are usually from axillary buds only,
or from terminal buds only; but in some they are both axillary and
terminal.

199. Inflorescence, which is the name used by Linnaeus to signify mode
of flower-arrangement, is accordingly of three classes : namely, Indeterminate,
when the flowers are in the axils of leaves, that is, are from axillary buds;
Determinate, when they are from terminal buds, and so terminate a stem
or branch ; and Mixed, when these two are combined.

200. Indeterminate Inflorescence (likewise, and for the same reason,
called indefinite inflorescence} is so named because, as the flowers all come
from axillary buds, the terminal bud may keep on growing and prolong the
stem indefinitely. This is so in Moneywort (Fig. 199).

SECTION 8.J

INFLORESCENCE.

73

201. "When Sowers thus arise singly from the axils of ordinary leaves,
they are axillary and solitary, not collected into flower-clusters.

202. But when several or many flowers are produced near each other,
the accompanying leaves are

apt to be of smaller size, or of
different shape or character :
then they are called BRACTS,
and the flowers thus brought ;
together form a cluster. The
kinds of flower-clusters of the
indeterminate class have re-
ceived distinct names, according to their form and disposition. They are
principally Raceme, Corymb, Umbel, Spike, Head, Spadix, Catkin, and
Panicle.

203. In defining these it will be necessary to use some of the following
terms of descriptive botany which relate to inflorescence. If a flower is
stalkless, i. e. sits directly in the axil or other support, it is said to be
sessile. If raised on a naked stalk of its own (as in Fig. 199) it is pedun-
culate, and the stalk is a PEDUNCLE.

204. A peduncle on which a flower-cluster is raised is a
Common peduncle. That which supports each separate flower
of the cluster is a Partial peduncle, and is generally called a
PEDICEL. The portion of the general stalk along which
flowers are disposed is called the Axis of inflorescence, or,
when covered with sessile flowers, the Rhachis (back-bone),
and sometimes the Receptacle. The leaves of a flower-cluster
generally are termed BRACTS. But when bracts of different
orders are to be distinguished, those on the common pedun-
cle or axis, and which have a flower in their axil, keep the
name of bracts ; and those on the pedicels or partial flower-
stalks, if any, that of BRACTLETS or Bracteoles. The for-
mer is the preferable English name.

205. A Raceme (Fig. 200) is that form of flower-cluster
in which the flowers, each on their own foot-stalk or pedicel,
are arranged along the sides of a common stalk or axis of
inflorescence; as in the Lily of the Valley, Currant, Bar-
berry, one section of Cherry, etc. Each flower comes from
the axil of a small leaf, or bract, which, however, is often
so small that it might escape notice, and even sometimes (as
in the Mustard Family) disappears altogether. The lowest blossoms of a

raceme are of course the oldest, and therefore open first, aud the order of
blossoming *s ascending from the bottom to the top. The summit, never
being stopped by a terminal flower, may go on to grow, and often does
so (as in the common Shepherd's Purse), producing lateral flowers one
after another for many weeks.

206. A Corymb (Fig. 202) is the same as a raceme, except that it is
flat and broad, either convex, or level-topped. That is, a raceme becomes
a corymb by lengthening the lower pedicels while the uppermost remain

shorter. The axis of a corymb is short in proportion to the lower pedicels
By extreme shortening of the axis the corymb may be converted into

207. An Umbel (Fig. 203) as in the Milkweed, a sort of flower-cluster
where the pedicels all spring apparently from the same point, from the top
of the peduncle, so as to resemble, when spreading, the rays of an umbrella ;
whence the name. Here the pedicels are sometimes called the
Rays of the umbel. And the bracts, when brought in this way
into a cluster or circle, form what is called an INVOLUCKE.

208. The corymb and the umbel being more or less level-
topped, bringing the flowers into a horizontal plane or a con-
vex form, the ascending order of development appears as Cen-
tripetal. That is, the flowering proceeds from the margin or
circumference regularly towards the centre ; the lower flowers
of the former answering to the outer ones of the latter.

209. In these three kinds of flower-clusters, the flowers are
raised on conspicuous pedicels (204) or stalks of their own. The
shortening of these pedicels, so as to render the flowers sessile
or nearly so, converts a raceme into a Spike, and a corymb or an
umbel into a Head*

210. A Spike is a flower-cluster with a more or less length-
ened axis, along which the flowers are sessile or nearly so ; as in

804 the Plantain (Fig. 204).

which are sessile on a very short axis or receptacle, as in the Button-ball,
Button-bush (Fig. 205), and Red Clover. It is just what a spike would

become if its axis were shortened ; or an umbel, if its pedicels were all

shortened until the flowers became sessile. The head

of the Button-bush is naked ; but that of the Thistle,

of the Dandelion, and the like, is surrounded by empty

bracts, which form an Involucre. Two particular forms

of the spike and the head have received particular

name?, namely, the 3padix and the Catkin.

212. A Spadix is a fleshy spike or head, with small,
and often imperfect flowers, as in the Calla, Indian
Turnip, (Fig. 206), Sweet Flag, etc. It is commonly
surrounded or embraced by a peculiar enveloping leaf,
called a SPATHE. r

213. A Catkin, or Ament, is the name given to the
scaly sort of spike of the Birch (Fig. 207) and Alder,
the Willow and Poplar, and one sort of flower-clusters
of the Oak, Hickory, and the like, — the so-called Amen-
taceous trees.

214. Compound flower-clusters of these kinds are
not uncommon. When the stalks which in the sim-
ple umbel are the pedicels of single flowers themselves
branch into an umbel, a Compound Umbel is formed.

FLOWERS.

[SECTION 8.

This is the inflorescence of Caraway (Fig. 208), Parsnip, and almost all of
the great family of Umbelliferous (umbel-bearing) plants.

215. The second-
ary or partial umbels
of a compound um-
bel are UMBELLETS.
When the umbellets
are subtended by an
involucre, this sec-
ondary involucre is
208 called an INVOLUCEL.

216. A Compound raceme is a cluster of racemes
racemosely arranged, as in Smilaciua racemosa. A
compound corymb is a corymb some branches of which
branch again in the same way, as in Mountain Ash. A
compound spike is a spicately disposed cluster of spikes.

217. A Panicle, such as that of Oats and many
Grasses, is a compound flower-cluster of a more or less
open sort which branches with apparent irregularity,
neither into corymbs nor racemes. Fig. 209 repre-
sents the simplest panicle. It is, as it were, a raceme
of which some of the pedicels have branched so as to
bear a few flowers on pedicels of their own, while

others remain simple. A compound panicle is one that 209

branches in this v/ay again and again.

218. Determinate Inflorescence is that in which the flowers are from
terminal buds. The simplest case is that of a solitary terminal flower, as

in Fig. 210. This stops the growth of the stem ; for its terminal bud, be-
coming a blossom, can no more lengthen in the manner of a leaf-bud. Any

further growth must be from axillary buds developing into branches. If
such branches are leafy shoots, at length terminated by single blossoms,
the inflorescence still consists of solitary flowers at the summit of stem and
branches. But if the flowering branches bear only bracts in place of ordi-
nary leaves, the result is the kind of flower-cluster called

219. A Cyme. This is commonly a flat-topped or convex flower cluster,
like a corymb, only the blossoms are from terminal buds. ,.
Fig. 211 illustrates the simplest cyme in a plant with oppo- ^ 0jT 'fy
site leaves, namely, with three flowers. The middle flower, ^l jr
a, terminates the stem ; the two others, b b, terminate branches, V /
one from the axil of each of the uppermost leaves ; and being

later than the middle one, the flowering proceeds from the
centre outwards, or is Centrifugal. This is the opposite of
the indeterminate mode, or that where all the flower-buds are
axillary. If flowering branches appear from the axils below,
the lower ones are the later, so that the order of blossoming
continues centrifugal or, which is the same thing, descending,
as in Fig. 213, making a sort of reversed raceme or false ra-
cent, — a kind of cluster which is to the true raceme just
what the flat cyme is to the corymb.

220. Wherever there are bracts or leaves, buds may be 213
produced from their axils and appear as flowers. Fig. 212 represents the
case where the brandies, b b, of Fig. 211, each with a pair of small leaves
or bracts about their middle, have branched again, and produced the
branchlets and flowers c c, on each side. It is the continued repetition of
this which forms the full or compound cyme, such as that of the Laures-
tiuus, Hobble-bush, Dogwood, and Hydrangea (Fig. 214).

221. A Fascicle (meaning a bundle), like that of the Sweet William
and Lychnis of the gardens, is only a cyme with the flowers much crowded.

222. A Glomerule is a cyme still more compacted, so as to imitate a
head. It may be known from a true head by the flowers not expanding
centripetally, that is, not from the circumference towards the centre.

223. The illustrations of determinate or cymose inflorescence have been
taken from plants with opposite leaves, which give rise to the most regular
cymes. But the Rose, Cinquefoil, Buttercup, etc., with alternate leaves,
furnish also good examples of cymose inflorescence.

224. A Cymule (or diminutive cyme) is either a reduced small cyme of
few flowers, or a branch of a compound cyme, i. e. a partial cyme.

225. Scorpioid or Helicoid Cymes, of various sorts, are forms of de-
terminate inflorescence (often puzzling to the student) in which one half of
the ramification fails to appear. So that they may be called incomplete
cymes. The commoner forms may be understood by comparing a complete

branches, which if present would

kinds of false racemes (219). When
the bracts are also wanting in such
cases, as in many Borragineous
plants, the true nature of the in-
florescence is very much disguised.

SECTION 8.J ORGANS OF THE FLOWER. 79

226. These distinctions between determinate and indeterminate inflores-
cence, between corymbs and cymes, and between the true and the false
raceme and spike, were not recognized by botanists much more than half
a century ago, and even now are not always attended to in descriptions.
It is still usual and convenient to describe rounded or flat-topped and open
ramification as corymbose, even when essentially cymose; also to call the
reversed or false racemes or spikes by these (strictly incorrect) names.

227. Mixed Inflorescence is that in whicli the two plans are mixed or
combined in compound clusters. A mixed panicle is one in which, while
the primary ramification is of the indeterminate order, the secondary or
ultimate is wholly or partly of the determinate order. A contracted or
elongated inflorescence of this sort is called a THYRSUS. Lilac and Horse-
chestnut afford common examples of mixed inflorescence of this sort. When
loose and open such flower-clusters are called by the general name of
Panicles. The heads of Composite are centripetal; but the branches o|
peduncles which bear the heads are usually of centrifugal order.

§2. PARTS OR ORGANS OF THE FLOWER.

228. These were simply indicated in Section II. 16. Some parts are
necessary to seed-bearing ; these are Essential Organs, namely, the Stamens
and Pistils. Others serve for protection or for attraction, often for both.
Such are the leaves of the Flower, or the Floral Envelopes.

229. The Floral Envelopes, taken together, are sometimes called the
PERIANTH, also Perigone, in Latin form Perigonium. In a flower which
possesses its full number of organs, the floral envelopes are of two kinds,
namely, an outer circle, the CALYX, and an inner, the COROLLA.

230. The Calyx is commonly a circle of green or greenish leaves, but
not always. It may be the most brightly colored part of the blossom.
Each calyx-leaf or piece is called a SEPAL.

231. The Corolla is the inner circle of floral envelopes or flower-leaves,
usually of delicate texture and colored, that is, of some other color than
'green. Each corolla-leaf is called a PETAL.

1 232. There are flowers in abundance whbli consist wholly of floral envel-
opes. Such are the so-called full double flowers, of which the choicer roses
and camellias of the cultivator are familiar examples. In them, under the
gardener's care and selection, petals have taken the place of both stamens
and pistils. These are monstrous or unnatural flowers, incapable of pro-
ducing seed, and subservient only to human gratification. Their common
name of double flowers is not a sensible one : except that it is fixed by
custom, it were better to translate their Latin name, fores pleni, and call
them full flowers, meaning full of leaves.

233. Moreover, certain plants regularly produce neutral flowers, consisv-
mg of floral envelopes only. In Fig. 214, some are seen around the margin

of the cyme in Hydrangea. They are likewise familiar in the Hobble-bush
and in Wild-Cranberry tree, Viburnum Oxycoccus ; where they form an
attractive setting to the cluster of small and comparatively inconspicuous

perfect flowers which they adorn. In the Guelder Rose, or Snow-ball of
ornamental cultivation, all or most of the blossoms of this same shrub ara
transformed into neutral flowers.

234. The Essential Organs are likewise
of two kinds, placed one above or within
the other ; namely, first, the STAMENS or
fertilizing organs, and second, the PISTILS,
which are to be fertilized and bear the

235. A Stamen consists of two parts,
namely, the FILAMENT or stalk (Fig. 219 a),
and the ANTHER (£). The latter is the only

essential part. It is a case, commonly with two lobes or cells, each opening
lengthwise by a slit, at the proper time, and discharging a powder or dust-
like substance, usually of a yellow color. This powder is the POLLEN, or
fertilizing matter, to produce which is the office of the stamen.

236. A Pistil (Fig. 220, 221) when complete, has three parts; OVAEY,
STYLE, and STIGMA. The Ovary, at base, is the hollow portion, which con-
tains one or more OVULES or rudimentary seeds. The Style is the tapering

portion above : the Stigma is a portion of the style, usually its tip, with
moist naked surface, upon which grains of pollen may
lodge and adhere, and thence make a growth which ex-
tends down to the ovules. When there is no style then
the stigma occupies the tip of the ovary.

237. The Torus or Receptacle is the end of the
flower-stalk, or the portion of axis or stem out of which
the several organs of the flower grow, upon which they
are borne (Fig. 223).

238. The parts of the flower are thus disposed on the
receptacle or axis essentially as are leaves upon a very
short stem ; first the sepals, or outer floral leaves ; then
the petals or inner floral leaves ; then the stamens ; lastly,
at summit or centre, the pistils, when there are two or
more of them, or the single pistil, when only one. Fig.
223 shows the organs displayed, two of each kind, of such
a simple and symmetrical flower as that of a Sedum or
Stonecrop, Fig. 222.

221
§ 3. PLAN OF FLOWER.

239. All flowers are formed upon one general plan, but with almost In-
finite variations, and many disguises. This common plan is best understood
by taking for a type, or standard for comparison, some perfect, complete,

regular, and symmetrical blossom, and one as simple as such a blossom
could well be. Flowers are said to be

Perfect (hermaphrodite), when provided with both kinds of essential or-
gans, i. e. with both stamens and pistils.

Complete, when, besides, they have the two sets of floral envelopes, namely,

calyx and corolla. Such are completely furnished with all that belongs to

a flower.

Regular, when all the parts of each set are alike in shape and size.
Symmetrical, when there is an equal number of parts in each set or circle

of organs.

240. Flax-flowers were taken for a pattern in Section II. 16. But in

them the five pistils have their ovaries as it were consolidated into one body.
Sedum, Fig. 222, has the pistils and all the other parts
free from such combination. The flower is perfect,
complete, regular, and symmetrical, but is not quite
as simple as it might be ; for there are twice as many
stamens as there are of the other organs. Crassula,
a relative of Sedum, cultivated in the conservatories
for winter blossoming (Fig. 224) is simpler, being
isostemonous, or with just as many stamens as petals or
sepals, while Sedum is diplostemonous, having double
that number : it has, indeed, two sets of stamens.

241. Numerical Plan. A certain number either
rmis ^irouSn tne flower or is discernible in some of
^s Par^s< This number is most commonly either five
or three, not very rarely four, occasionally two. Thus
the ground-plan of the flowers thus far used for illus-
tration is five. That of Trillium (Fig. 226, 227) is

three, as it likewise is as really, if not as plainly, in Tulips and Lilies, Crocus,

Iris, and all that class of blossoms. In some Sedums all the flowers are

in fours. In others the first flowers are

on the plan of five, the rest mostly on

the plan of four, that is, with four sepals,

four petals, eight

stamens (i. e. twice

four), and four pis-
tils. Whatever the

ground number may

be, it runs through

the whole in symmet-
rical blossoms.
242. Alternation of the successive Circles. In these flowers the

parts of the successive circles alternate ; and such is the rule. That is,

the petals stand over the intervals between the sepals ; the stamens, when
of the same number, stand over the intervals between the petals ; or when
twice as many, as in the Trillium, the outer set alternates with the petals,
and the inner set, alternating with the other, of course stands before the
petals ; and the pistils alternate with these. This i's just as it should be on
the theory that the circles of the blossom answer to whorls of leaves, which
alternate in this way. While in such flowers the circles are to be regarded
as whorls, in others they are rather to be regarded as condensed spirals of
alternate leaves. But, however this may be, in the mind of a morphological
botanist,

243. Flowers are altered Branches, and their parts, therefore, altered
leaves. That is, certain buds, which might have grown and lengthened
into a leafy branch, do, under other circumstances and to accomplish other
purposes, develop into blossoms. In these the axis remains short, nearly
as it is in the bud ; the leaves therefore remain close together in sets or
circles ; the outer ones, those of the calyx, generally partake more or less
of the character of foliage ; the next set are more delicate, and form the co-
rolla, while the rest, the stamens and pistils, appear under forms very dif-
ferent from those of ordinary leaves, and are concerned in the production
of seed. This view gives to Botany an interest which one who merely no-
tices the shape and counts the parts of blossoms, without understanding
their plan, has no conception of.

244. That flowers answer to branches may be shown, first, from their
position. As explained in the section on Inflorescence, flowers arise from
the same places as branches, and from no other ; flower-buds, like leaf-buds,
appear either on the summit of a stem, that is, as a terminal bud, or in the
axil of a leaf, as an axillary bud. And, as the plan of a symmetrical flower
shows, the arrangement of the parts on their axis or receptacle is that ol
leaves upon the stem.

245. That the sepals and petals are of the nature of leaves is evident
from their appearance ; they are commonly called the leaves of the flower.
The calyx is most generally green in color, and foliaceous (ieaf-like) in
texture. And though the corolla is rarely green, yet neither are proper
leaves always green. In our wild Painted-cup, and in some scarlet Sages,
common in gardens, the leaves just under the flowers are of the brightest
red or scarlet, often much brighter-colored than the corolla itself. And
sometimes (as in many Cactuses, and in Carolina Allspice) there is such a
regular gradation from the last leaves of the plant (bracts or bractlets) into
the leaves of the calyx, that it is impossible to say where the one ends and
the other begins. If sepals are leaves, so also are petals ; for there is no
clearly fixed limit between them. Not only in the Carolina Allspice and
Cactus (Fig. 229), but in the Water-Lily (Fig. 228) and in a variety of
flowers with more than one row of petals, there is such a complete transi-
tion between calyx and corolla that no one can surely tell how many of the
leaves belong to the one and how many to the other.

84

FLOWERS.

[SECTION 8.

246. That stamens are of the same general nature as petals, and there-
fore a modification of leaves, is shown by the gradual transitions that occur

between the one and the
other in many blos-
soms; especially in cul-
tivated flowers, such as
Roses and Camellias,
when they begin to
double, that is, to change
their stamens into pet-
s. Some wild and
natural flowers show
the same interesting
transitions. The Caro-
lina Allspice and the
White Water-Lily ex-
hibit complete grada-

228 tions not only between

sepals and petals, but

between petals and stamens. The sepals of our Water-Lily are green out-
side, but white and petal-like on the inside ; the petals, in many rows,
gradually grow narrower towards the centre of the flower ; some of these
are tipped with a trace of a yellow
anther, but still are petals ; the
next are more contracted and sta-
men-like, but with a flat petal-like
filament; and a further narrow-
ing of this completes the genuine
stamen.

247. Pistils and stamens now
and then change into each other in
some Willows ; pistils often turn
into petals i« cultivated flowers ;
and in the Double Cherry they
are occasionally replaced by small
green leaves. Sometimes a whole
blossom changes into a cluster of
green leaves, as in the "green
roses " occasionally noticed in gar-
dens, and sometimes it degenerates into a leafy branch. So the botanist
regards pistils also as answering to leaves ; that is, to single leaves when
simple and separate, to a whorl of leaves when conjoined.

SECTION 8.J MODIFICATIONS OF THE TYPE.

§ 4. MODIFICATIONS OF THE TYPE.

248. The Deviations, as they may be called, from the assumed type or
pattern of flower are most various and extensive. The differences between
one species and another of the same genus are comparatively insignificant ;
those between different genera are more striking ; those between different
families and classes of plants more and more profound. They represent
different adaptations to conditions or modes of life, some of which have
obvious or probable utilities, although others are beyond particular expla-
nation. The principal modifications may be conveniently classified. First
those which in place of perfect (otherwise called hermaphrodite or bisexual)
flowers, give origin to

249. Unisexual, or Separated, or Diclinous Flowers, imperfect flow-
ers, as they have been called in contradistinction to perfect flowers ; but that

term is too ambiguous. In
these some flowers want the
stamens, while others want the pistils. Taking
hermaphrodite flowers as the patten;, it is natural
to say that the missing organs are suppressed. This
expression is justified by the very numerous cases
in which the missing parts are abortive, that is,
are represented by rudiments or vestiges, which
serve to exemplify the plan, although useless as

to office. Unisexual flowers are
Monoecious (or Monoicous, i. e. of one household), when flowers of both

sorts or sexes are produced by the same individual plant, as in the Ricinus

or Castor-oil Plant, Fig. 230.

Dioecious (or Dioicous, i. e. of separate households), when the two kinds

are borne on different plants ; as in Willows, Poplars, Hemp, and Moon-

seed, Fig. 231, 232.

Polygamous, when the flowers are some of them perfect, and some

staminate or pistillate only.

FLOWERS.

[SECTION 8,

250. A blossom having stamens and no pistil is a Staminate or Male
flower. Sometimes it is called a Sterile flower, not appropriately, for other
flowers may equally be sterile. One having pistil but no stamens is a
Pistillate or Female flower.

251. Incomplete Flowers are so named
in contradistinction to complete : they want
either one or both of the floral envelopes.
Those of Fig. 230 are incomplete, having ca-
lyx but no corolla. So is the flower of Anem-
one (Fig. 233), although

i its calyx is colored like a
corolla. The flowers of
Saururus or Lizard's-tail, 233

although perfect, have neither calyx nor corolla (Fig.
234). Incomplete flowers, accordingly, are

Naked or Achlamydeous, destitute of both floral en-
velopes, as in Fig. 234, or
Apetalous, when wanting only the corolla. . The case of corolla present
and calyx wholly wanting is extremely rare, although there are seeming
instances. In fact, a single or simple perianth is taken to be a calyx,
unless the absence or abortion of a calyx can be made evident.

252. In contradistinction to
regular and symmetrical, very
many flowers are

Irregular, that is, with the
members of some or all of the
floral circles unequal or dissim-
ilar, and

Unsymmetrical, that is, when
the circles of the flower or
some of them differ in the num-
ber of their members. (Sym-
metrical and unsymmetrical are
used in a different sense in some
recent books, but the older use
should be adhered to.) Want
of numerical symmetry and
irregularity commonly go to-
gether; and both are common.
Indeed, few flowers are entirely

symmetrical beyond calyx, corolla, and perhaps stamens ; and probably no
irregular blossoms are quite symmetrical.
853. Irregular and Unsymmetrical Flowers may therefore be illus-

trated together, beginning with cases
which are comparatively free from other
complications. The blossom of Mustard,
\ and of all the very natural family which
\ it represents (Fig. 235, 236), is regular
J I) but unsymmetrical in the stamens. There
/ are four equal sepals, four equal petals ;
but six stamens, and only two members
in the pistil, which for the present may

be left out of view. The want of symmetry is in the stamens. These are in
two circles, an outer and an inner. The outer circle consists of two stamens
only; the inner has its proper number of four. The flower of Violet, which
is on the plan of five, is symmetrical in calyx, corolla, and stamens, inas-
much as each of these circles consists of five members ; but it is conspicu-
ously irregular in the corolla, one of the petals being very different from the
rest.

254. The flowers of Larkspur, and of Monkshood or Aconite, which are
nearly related, are both strikingly irregular in calyx and corolla, and con-
siderably unsymmetrical. In Larkspur (Fig. 239-241) the irregular calyx
consists of five sepals, one of which, larger than the rest, is prolonged be-
uind into a large sac or spur; but the corolla is of only four petals (of two
shapes), — the fifth, needed to complete the symmetry, being left out. And
the Monkshood (Fig. 242-244) has five very dissimilar sepals, and a corolla
of only two very small and curiously-shaped petals, — the three needed to
make up the symmetry being left out. The stamens in both are out of
symmetry with the ground-plan, being numerous. So are the pistils, which
are usually diminished to three, sometimes to two or to one.

255. Flowers with Multiplication of Parts are very common. The

stamens are indefinitely numerous
in Larkspur and in* Monkshood
(Fig. 242, 243), while the pistils
are fewer than the ground-plan
\ suggests. Most Cactus -flowers
have all the organs much in-
creased in number (Fig. 229),
and so of the Water-Lily. In
Anemone (Fig. 233) the stamens
and pistils are multiplied while
the petals are left out. In Buttercups or Crowfoot, while the sepals and
petals conform to the ground-plan of five, both stamens and pistils are indefi-
nitely multiplied (Fig. 245).

256. Flowers modified by Union of Parts, so that these parts more
or less lose the appearance of separate leaves or other organs growing out
of the end of the stem or receptacle, are extremely common. There are two
kinds of such union, namely : —

Coalescence of parts of the same circle by their contiguous margins; and
Adnation, or the union of adjacent circles or unlike parts.

257. Coalescence is not rare in leaves, as in the upper pairs of Honey-
suckles, Fig. 163. It may all the more be expected in the crowded circles
or whorls of flower-leaves. Datura or Stramonium (Fig. 246) shows this
coalescence both in calyx and corolla, the five sepals and the five petals be-
ing thus united to near their tips, each into a tube or long and narrow cup.
These unions make needful the following terms : —

FIG. 245. Flower of Ranunculus bulbosus, or Buttercup, in section.

SECTION 8.] MODIFICATIONS OF THE TYPE.

89

Gamopetalous, said of a corolla the petals of which are thus coalescent
into one body, whether only at base or higher. The union may extend to
the very summit, as in Morning Glory and
the like (Fig. 247), so that the number of
petals hi it may not be apparent. The old
name for this was Monopetalous, but that
means " oue-petalled ; " while gamopetalous
means " petals united," and therefore is the
proper term.

Polypetalous is the counterpart term, to
denote a corolla of distinct, that is, separate
petals. As it means " many petalled/' it is
not the best possible name, but it is the old
one and in almost universal use.

Gamosepalous applies to the calyx when
the sepals are in this way united.

Polysepalous, to the calyx when of sepa-
rate sepals or calyx-leaves.

258. Degree of union or of separation in
descriptive botany is expressed in the same
way as is the lobing of leaves (139). See
Fig. 249-253, and the explanations.

259. A corolla when gamopetalous com-
monly shows a distinction (well marked in
Fig. 249-251) between a contracted tubular
portion below, the TUBE, and the spread-
ing part above, the BORDER or LIMB. The
junction between tube and limb, or a more
or less enlarged upper portion of the tube
between the two, is the THROAT. The
same is true of the calyx.

260. Some names are given to partic-
ular forms of the gamopetalous corolla,
applicable also to a gamosepalous calyx,
such as

Wheel-shaped, or Rotate; when spread-
ing out at once, without a tube or with
a very short one, something in the shape
of a wheel or of its diverging spokes, Fig.
252, 253.

Salver-shaped, or Salver-form ; when a flat-spreading border is raised on

a narrow tube, from which it diverges at right angles, like the salver rep-

Bell-shaped, or Campanulate ; where
a short and broad tube widens upward,
in the shape of a bell, as in Fig. 254.

Funnel-shaped, or Funnel-form ; grad-
ually spreading at the summit of a tube which is narrow below, in the

91

Tubular ; when prolonged into a tube, with little or no spreading at the
border, as in the corolla of the Trumpet Honeysuckle, the calyx of Stra-
monium (Fig. 246), etc.

261. Although sepals and petals are usually all blade or lamina (123),
1'ke a sessile leaf, yet they may have a contracted and stalk-like base, an-
swering to petiole. This
is called its CLAW, in
Latin Unguis. Unguicu-
late petals are universal
and strongly marked in
the Pink tribe, as in
Soapwort (Fig. 248).

262. Such petals, and
various others, may have
260 an outgrowth of the in-

ner face into, an appendage or fringe, as in Soapwort, and in Silene (Fig.
259), where it is at the junction of
claw and blade. This is called a
CROWN, or Corona. In Passion-
flowers (Fig. 260) the crown consists
of numerous threads on the base of
each petal.

263. Irregular Flowers may be
polypetalous, or nearly so, as in the
papilionaceous corolla; but most of
them are irregular through coales-
cence, which often much disguises
the numerical symmetry also. As
affecting the corolla the following
forms have received particular names :

264. Papilionaceous Corolla,
Fig. 261, 262. This is polypetalous,
except that two of the petals cohere,
usually but slightly. It belongs only
to the Leguminous or Pulse family.
The name means butterfly-like; but
the likeness is hardly obvious. The
names of the five petals of the
papilionaceous corolla are curiously
incongruous. They are,

FLOWERS.

[SECTION 8>

The STANDARD or Banner (Vexilluni), the large upper petal which is

external in the bud and wrapped around the others.
The WINGS (Alee), the pair of side petals, of quite different shape from

the standard.
The KEEL (Carina), the two lower and usually smallest petals ; these are

lightly coalescent into a body which bears some likeness, not to the keel,

but to the prow of a boat ; and this encloses the stamens and pistil. A

Pea-blossom is a typical example ; the present illustration is from a species

of Locust, Robinia hispida.

265. Labiate Corolla (Fig. 256-258), which would more properly have
been called Bilabiate, that is, two-lipped.
This is a common form of gamopetalous co-
rolla ; and the calyx is often bilabiate also.
These flowfers are all on the plan of five ;
and the irregularity in the corolla is owing
to unequal union of the petals as well as to
diversity of form. The two petals of the
upper or posterior side of the flower unite
with each other higher up than with the
lateral petals (in Fig. 256, quite to the top),
forming the Upper lip : the lateral and the
lower similarly unite to form the Lower lip.
The single notch which is generally found
at the summit of the upper lip, and the two
notches of the lower lip, or in other words
the two lobes of the upper and the three of
the lower lip, reveal the real composition.
So also does the alternation of these five
parts with those of the calyx outside. When
the calyx is also bilabiate, as in the Sage,
this alternation gives three lobes or sepals
to the upper and two to the lower lip. Two
forms of the labiate corolla have been desig-
nated, viz. : —

Eingent or Gaping, when the orifice is
wide open, as in Fig. 256.

Personate or Masked, when a protube-
rance or intrusion of the base of the lower
lip (called a Palate) projects over or closes

the orifice, as in Snapdragon and Toad-Flax, Fig. 257, 258.

266. There are all gradations between labiate and regular corollas. In
those of Gerardia, of some species of Pentstemon, and of Catalpa (Fig.
263-265), the labiate character is slight, but is manifest on close inspection.
In almost all such flowers the plan of five, which is obvious or ascertain-
able in the calyx and corolla, is obscured in the stamens by the abortion or
suppression of one or three of their number.

267. Ligulate Corolla. The ligulate or Strap-shaped corolla mainly
belongs to the family of Composite, in which numerous small flowers are

gathered into a head, within an involucre that imitates a calyx. It is best
exemplified in the Dandelion and in Chiccory (Fig. 266). Each one of
these straps or Ligules, looking like so many petals, is the corolla of a dis-

tinct flower : the base is a short tube, which opens out into the ligule : the
five minute teeth at the end indicate the number of constituent petals. So
this is a kind of gamopetalous corolla, which is open along one side nearly

to the base, and outspread. The nature of such a corolla (and of the sta-
mens also, to be explained in the next section) is illustrated by the flower
of a Lobelia, Fig. 285.

268. In Asters, Daisies, Sunflower, Coreopsis (Fig. 268), and the like,
only the marginal (or Ray) corollas are ligulate ; the rest (those of the

Disk) are regularly gamopetalous,
tubular, and five-lobed at summit ;
' but they are small and individually
inconspicuous, only the ray-fowers
iking a show. In fact, those of
Coreopsis and of Sunflower are
simply for show, these ray -flowers
being not only sterile, but neutral,
that is, having neither stamens
nor pistil. But in Asters, Daisies,
Golden-rods, and the like, these ray-flowers are pistillate and fertile, serving

therefore for seed-bearing as well as for show. Let it not be supposed thax
the show is useless. See Section XIII.

269. Adnation, or Consolidation, is the union of the members of parts
belonging to different circles of the flower (256). It is of course under-
stood that in this (as likewise in coalescence) the parts are not formed and
then conjoined, but are produced in union. They are born united, as the
term adnate implies. To illustrate this kind of union, take the accompany
ing series of flowers (Fig. 270-274), shown in vertical section. In the
first, Fig. 270, Flax-flower, there is no adnation; sepals, petals, and sta-
mens, are free as well as distinct, being separately borne on the receptacle,
3ne circle within or above the next j only the five pistils have their ovaries
coalescent. In Fig. 271, a Cherry flower, the petals and stamens are borne
on the throat of the calyx-tube ; that is, the sepals are coalescent into a cup,
and the petals and stamens are adnate to the inner face of this ; in other

words, the sepals, petals, and stamens are all consolidated up to a certain
height. In Fig. 272, a Purslane-flower, the same parts are adnate to or
consolidated with the ovary up to
;ts middle. In Fig. 273, a Haw-
thorn-flower, the consolidation has I
extended over the whole ovary; I
and petals and stamens are adnate
to the calyx still further. In Fig.
274, a Cranberry-blossom, it is the
same except that all the parts are
free at the same height; all seem
to arise from the top of the ovary.

270. In botanical description,
to express tersely such differences
in the relation of these organs to
the pistil, they are said to be

Hypogynous (i. e. under the pis»
til) when they are all/ra?, that is,
not adnate to pistil nor connate
with each other, as in Fig. 270.

Perigynous (around the pistil)
when connate with each other,
that is, when petals and stamens
are inserted or borne on the calyx,
whether as in Cherry -flowers (Fig.
271) they are free from the pistil, f"
or as in Purslane and Hawthorn v
(Fig. 272, 273) they are also ad-
nate below to the ovary.

Epigynom (on the ovary) when
so adnate that all these parts ap-
pear to arise from the very summit of the ovary, as in Fig. 274. The
last two terms are not very definitely distinguished.

271. Another and a simpler form of expression is to describe parts of
the flower as being

Free, when not united with or inserted upon other parts.

Distinct, when parts of the same kind are not united. This term is the
counterpart of coalescent, as free is the counterpart of adnate. Many
writers use the term " free " indiscriminately for both ; but it is better to
distinguish them.

FLOWERS.

[SECTION 8.

Connate is a term common for either not free or not distinct, that is, foi
parts united congenitally, whether of same or of different kinds.
Adnate, as properly used, relates to the union of dissimilar parts.

272. In still another form of ex-
\ $^ \!ftl I/XT tffc^~^ pression, the terms superior and

MR Ull/ll ®?. , £ferior have been mjh used iu

) the sense of above and below.

Superior is said of the ovary of
Max-flower, Cherry, etc., because
above the other parts ; it is equiv-
alent to "ovary free/' Or it is
said of the calyx, etc., when above
the ovary, as in Eig. 273-275.

Inferior, when applied to the
ovary, means the same as " calyx
adnate ; " when applied to the flo-
ral envelopes, it means that they
are free.

273. Position of Flower or
of its Parts. The terms superior
and inferior, or upper and lower,
are also used to indicate the relative
position of the parts of a flower in
reference to the axis of inflores-
cence. An axillary flower stands between the bract or leaf which sub-
tends it and the axis or stem which bears this bract

or leaf. This is represented in
sectional diagrams (as in Fig. 275,
276) by a transverse line for the
bract, and a small circle for the axis
of inflorescence. Now the side of
the blossom which faces the bract
is the

Anterior, or Inferior, or Lower side ;
while the side next the axis is the
Posterior, or Superior, or Uppir side of the flower.
274. So, in the labiate corolla (Fig. 256-258), the lip which is composes
of three of the five petals is the Anterior, or inferiort or lower lip; the other
is the posterior, or superior, or upper lip.

275. In Violets (Fjg. 238, 276), the odd sepal is posterior (next the
axis) ; the odd petal is therefore anterior, or next the subtending leaf. In
the papilionaceous flower (Fig. 261, and diagram, Fig. 275), the odd sepal is
anterior, and so two sepals are posterior; consequently, by the alternation,
the odd petal (the standard) is posterior or upper, and the two petals form-
ing the keel are anterior or lower.

§ 5. ARRANGEMENT OF PARTS IN THE BUD.

276. ^Estivation was the fanciful name given by Linnaeus to denote
the disposition of the parts, especially the leaves of the flower, before An-
thesis, i. e. before the blossom opens. Prtefloration, a better term, is some-
times used. This is of importance in distinguishing different families or
genera of plants, being generally uniform in each. The aestivation is best
seen by making a slice across the flower-bud ; and it may be expressed in
diagrams, as in the accompanying figures.

277. The pieces of the calyx or the corolla either overlap each other in
the bud, or they do not. When they do not overlap, the eestivation is

Valvate, when the pieces meet each other by their
abrupt edges, without any infolding or overlapping;
as the calyx of the Linden or Basswood (Tig. 277).
Induplicate, which is valvate with the margins of
each piece projecting inwards, as in the calyx of a
common Virgin's-bower, Fig. 278, or

Involute^ which is the same but the margins rolled
inward, as in most of the large-flowered species of
Clematis, Fig. 279.

Heduplicate, a rarer modification of valvate, is similar but with margins
projecting outward.

Open, the parts not touching in the bud, as
the calyx of Mignonette.

278. When the pieces overlap in the bud, it
is in one of two ways ; either every piece has
one edge in and one edge out, or some pieces
are wholly outside and others wholly inside. In
the first case the aestivation is

Convolute, also named Contorted or Twisted, as in Fig. 280, a cross-sec-
tion of a corolla very strongly thus convolute or rolled up together, and in
the corolla of a Flax-flower (Fig. 281), where the petals only moderately
overlap in this way. Here one edge of every petal covers the next before

margin covered by the first while the \
other overlaps the third or innermost
piece: this is the arrangement of alternate three- 281

ranked leaves (187). When there are five pieces, as in the corolla of Fig.
825, and calyx of Fig. 281, as also of Fig. 241, 276, two are external,
two are internal, and one (the third in the spiral) has one edge covered
by the outermost, while its other edge covers the in-
nermost; which is just the five-ranked arrangement of
' alternate leaves (188). When the pieces are four, two
are outer and two are inner ; which answers to the ar-
rangement of opposite leaves.

279. The imbricate and the convolute modes some-
times vary one into the other, especially in the corolla.

280. In a gamopetalous corolla or gamosepalous calyx,
the shape of the tube in the bud may sometimes be notice-
able. It may be

Plicate or Plaited, that is, folded lengthwise ; and the
plaits may either be turned outwards, forming projecting
ridges, as in the corolla of Campanula; or turned in-
wards, as in that of Gentian Belladonna ; or

Supervolute, when the plaits are convolutely wrapped
round each other, as in the corolla of Morning Glory and of Stramonium,
Fig. 882.

SECTION IX. STAMENS IN PARTICULAR.

282. Insertion, or place of attachment. The stamens usually go with
the petals. Not rarely they are at base

Epipetalous, that is, inserted
on (or adnate to) the corolla, as
in Pig. 283. When free from
the corolla, they may be

Hypogynons, inserted on the
receptacle under the pistil or
gyncecium.

Perigynous, inserted on the
calyx, that is, with the lower
part of filament adnate to the
calyx-tube.

Epigynons, borne apparently on the top of the ovary; all which is ex-
plained in Fig. 270-274

Gynandrous is another term relating to insertion of rarer occurrence,
that is, where the stamens are
inserted on (in other words,
adnate to) the style, as in
r Lady's Slipper (Fig. 284), and
hi the Orchis family generally.
283. In Relation to each
a Other, stamens are more com-
monly

Distinct, that is, without any
union with each other. But
when united, the following
technical terms of long use 286
indicate their modes of mutual connection : —

Monadelphous (from two Greek words, meaning " in one brotherhood "),
when united by their filaments into one set, usually into a ring or cup
below, or into a tube, as in the Mallow Family (Fig. 286), the Passion-
flower (Fig. 260), the Lupine (Fig. 287), and in Lobelia (Fig. 285).

Diadelphous (meaning in two brotherhoods), when united by the fila-
ments into two sets, as in the Pea and most of its near relatives (Fig. 288),
usually nine in one set, and one in the other.

Triadelphous (three brotherhoods), when the filaments are united in three
sets or clusters, as in most species of Hypericum

Pentadelphous (five "brotherhoods), when in five sets, as in some species
of Hypericum and in American Linden (Fig. 277, 289).

Polyadelphous (many or several
brotherhoods) is the term generally
employed when these sets are several,
or even more than two, and the par-
ticular number is left unspecified.
These terms all relate to the fila-

wiwm^ \ \\\ \ \ meilts'

J7 yjSEl I \\ \ SI Syngenesious is the term to denote

that stamens have their anthers united,
coalescent into a ring or tube ; as in
Lobelia (Fig. 285), in Violets, and in
all of the great family of Composite.

284. Their Number in a flower is commonly expressed directly, but
sometimes adjectively, by a series of terms which were the name of classes
in the Linnsean artificial system, of which the following names, as also the
preceding, are a survival : —

Monandrous, i. e. solitary-stamened, when the flower has only one stamen,

Diandrous, when it has two stamens only,

Triandrous, when it has three
stamens,

Tetrandrous, when it has four
stamens,

Pentandrous, when it has
five stamens,

Hexandrous, when with six
stamens, and so on to

Polyandrous, when it has
many stamens, or more than a dozen.

285. For which terms, see the Glossary. They are all Greek numerals
prefixed to -andria (from the Greek), which Linnaeus used for andrcerium,
and are made into an English adjective, -androus. Two other terms, of
same origin, designate particular cases of number (four or six) in con-
nection with unequal length. Namely, the stamens are

Didynamous, when, being only four, they form two pairs, one pair longer
than the other, as in the Trumpet Creeper, in Gerardia (Fig. 263), etc.

ANTHERS.

I

Tetrad t/namous, when, being only six, four of them surpass the other
two, as in the Mustard-flower audall the Cruciferous family, Fig. 235.

286. The Filament is a kind of stalk to the anther, commonly slender
or thread-like : it is to the anther nearly what the petiole is to the blade of
a leaf. Therefore it is not an essential part. As a leaf may be without
a stalk, so the anther may be Sessile, or without a filament.

287. The Anther is the essential part of the stamen. It is a sort of
case, filled with a fine powder, the Pollen, which serves to fertilize the pis-
til, so that it may perfect seeds. The anther is said to be

Innate (as in Fig. 292), when it is attached by its base to the very apex
of the filament, turning neither inward nor outward ;

Adnate (as in Fig. 293), when attached
as it were by one face, usually for its whole
length, to the side of a continuation of the
filament; and

Versatile (as in Fig. 294), when fixed' by
or near its middle only to the very point of
the filament, so as to swing loosely, as in
the Lily, in Grasses, etc. Versatile or ad-
nate anthers are

Introrse, or Incumbent, when facing in-
ward, that is, toward the centre of the flow-
er, as in Magnolia, Water-Lily, etc.

Extrorse, when facing outwardly, as in the Tulip-tree.

288. Rarely does a stamen bear any resemblance to a leaf,
or even to a petal or flower-leaf. Nevertheless, the botanist's
idea of a stamen is that it answers to a leaf developed in a
peculiar form and for a special purpose. In the filament he
sees the stalk of the leaf; in the anther, the blade. The
blade of a leaf consists of two similar sides ; so the anther
consists of two LOBES or CELLS, one answering to the left, the
other to the right, side of the blade. The two lobes are often
connected by a prolongation of the filament, which answers
to the midrib of a leaf ; this is called the CONNECTIVE. This
is conspicuous in Fig. 292, where the connective is so broad
that it separates the two cells of the anther to some distance.

289. A simple conception of the morphological relation of
an anther to a leaf is given in Fig. 295, an ideal figure, the lower part rep-
resenting a stamen with the top of its anther cut away ; the upper, the
corresponding upper part of a leaf.

290. So anthers are generally two-celled. But as the pollen begins to
form in two parts of each cell (the anterior and the posterior), sometimes
these two strata are not confluent, and the anther even at maturity may be
four-celled, as in Moonseed (Fig. 296) ; or rather, in that case (the word
cell being used for each lateral half of the
organ), it is two-celled, but the cells bilocel-
late.

291. But anthers may become one-celled,
and that either by confluence or by suppres
sion.

292. By confluence, when the two cells
run together into one, as they nearly do in
most species of Pentstemou (Fig. 297), more
so in Monarda (Fig. 300), and completely

in the Mallow (Fig. 298) and all the Mallow family.

293. By suppression m certain cases the anther may be reduced to one
cell or halved. In Globe Amaranth (Fig. 299) there is a single cell without
vestige of any other. Different species of Sage and of the White Sages of
California show various grades of abortion of one of the anther-cells, along
with a singular lengthening of the connective (Fig. 302-305).

294. The splitting open of an anther for the discharge of its pollen is
termed its Dehiscettce.

295. As the figures show, this is commonly by a line along the whole
length of each cell, either lateral or,

when the anthers are extrorse, often
along the outer face, and when introrse,
along the inner face of each cell. Some-
times the opening is only by a chink, hole,
or pore at the top, as in the Azalea, Py-
rola (Fig. 307), etc. ; sometimes a part of
the face separates as a sort of trap-door
(or valve), hinged at the top, and open-
ing to allow the escape of the pollen,
as in the Sassafras, Spice-bush, and Barberry (Fig. 308).

296. Pollen, This is the powdery matter, commonly of a yellow color,
which fills the cells of the anther, and is discharged during blossoming,

809 810 811 812 818

after which the stamens generally fall or wither away. Under the micro
scope it is found to consist of grains, usually round or oval, and all alike
in the same species, but very different in different plants. So that the

plant may sometimes be recognized from the pollen alone. Several forms
are shown in the accompanying figures.

297. An ordinary pollen-grain has two coats ; the outer coat chickish,
but weak, and frequently adorned with lines or bands, or studded with
points ; the inner coat is extremely thin and delicate, but extensible, and
its cavity when fresh contains a thickish protoplasmic fluid, often rendered
turbid by an immense number of minute particles that float in it. As the
pollen matures this fluid usually dries up, but the protoplasm does not lose
its vitality. When the grain is wetted it absorbs water, swells up, aud is
apt to burst, discharging the contents. But when weak

syrup is used it absorbs this slowly, and the tough in-
ner coat will sometimes break through the outer and
begin a kind of growth, like that which takes place when
the pollen is placed upon the stigma.

298. Some pollen - grains are, as it
were, lobed (as in Tig. 315, 316), or
formed of four grains united (as in the
Heath family, Fig. 317) : that of Pine
(Fig. 318) has a large rounded and empty
bladder-like expansion upon each side.
This renders such pollen very buoyant,
and capable of being trans-
ported to a great distance

by the wind.

299. In species of Acacia
simple grains lightly cohere
into globular pellets. In
Milkweeds and in most
Orchids all the pollen of an

anther-cell is compacted or coherent into one mass, called a Potten-mass, o
POLLINIUM, plural POLLINIA. (Fig. 319-322.)

SECTION 10.] PISTILS. 105

SECTION X. PISTILS IN PARTICULAR.

§ 1. ANOIOSPERMOUS OR ORDINARY GYNOSCIUM.

300. Gyncecium is the technical name for the pistil or pistils of a
flower taken collectively, or for whatever stands in place of these. The
various modifications of the gyncecium and the terms which relate to
them require particular attention.

301. THE PISTIL, when only one, occupies the centre of the flower;
when there are two pistils, they stand facing each other in the centre of
the flower ; when several, they commonly form a ring or circle ; and when
very numerous, they are generally crowded in rows or spirals on the sur-
face of a more or less enlarged or elongated receptacle. Their number
gives rise to certain terms, the counterpart of those used for stamens (284-),
which are survivals of the names of orders in the Linnsean artificial system.
The names were coined by prefixing Greek numerals to -gynia used for
gynoecium, and changed into adjectives in the form of -gynous. That is, a
flower is

Monogynous, when it has a single pistil, whether that be simple or com-
pound ;

Digynous, when it has only two pistils ; Trigynous, when with three ;
Tetragynous, with four ; Pentagynous, with five ; Hexagynous, with six ;
and so on to Polygynous, with many pistils.

302. The Parts of a Complete Pistil, as already twice explained (16,
236), are the OVARY, the STYLE, and the STIGMA. The ovary is one es-
sential part: it contains the rudiments of seeds, called OVULES. The
stigma at the summit is also essential : it receives the pollen, which fer-
tilizes the ovules in order that they may become seeds. But the style,
commonly a tapering or slender column borne on the summit of the ovary,
and bearing the stigma on its apex or its side, is no more necessary to a
pistil than the filament is to the stamen. Accordingly, there is no style in
many pistils : in these the stigma is sessile, that is, rests directly on the
ovary (as in Fig. 326). The stigma is very various in shape and appear-
ance, being sometimes a little knob (as in the Cherry, Fig. 271), sometimes
a point or small surface of bare tissue (as in Fig. 327-330), and sometimes
a longitudinal crest or line (as in Fig. 324, 341-343), or it may occupy the
whole length of the style, as in Fig. 331.

303. The word Pistil (Latin, Pistillum) means a pestle. It came into
use in the first place for such flowers as those of Crown Imperial, or Lily,
iu which the pistil in the centre was likened to the pestle, and the perianth
around it to the mortar, of the apothecary.

304. A pistil is either simple or compound. It is simple when it answers
to a single flower-leaf, compound when it answers to two or three, or a
fuller circle of such leaves conjoined.

106

SIMPLE PISTILS.

[SECTION 10.

305. Carpels. It is convenient to have a name for each flower-leaf of
the gyncecium ; so it is called a Carpel, in Latin Carpellum or Carpidium.
A simple pistil is a carpel. Each component flower-leaf of a compound
pistil is likewise a carpel. When a flower has two or more pistils, these
of course are simple pistils, that is, separate carpels or pistil-leaves. There
may be only a single simple pistil to the flower, as in a Pea or Cherry
blossom (Fig. 271) ; there may be two such, as in many Saxifrages ; or
many, as in the Strawberry. More commonly the single pistil in the
centre of a blossom is a compound one. Then there is seldom much
difficulty in ascertaining the number of carpels or pistil-leaves that com-
pose it.

306. The Simple Pistil, viewed morphologically, answers to a leaf,
blade with margins incurved and united where they meet, so forming a
closed case or pod (the ovary), and bearing ovules at the suture or junction
of these margins : a tapering upper portion with margins similarly inrolled,
is supposed to form the style ; and these same margins, exposed at the tip
or for a portion of the length, become the stigma. Compare, under this
view, the three accompanying figures.

307. So a simple pistil should have a one-celled ovary, only one line of

attachment for the ovules, a single style,
and a single stigma. Certain variations
from this normal condition which some-
times occur do not invalidate this mor-
phological conception. For instance, the
stigma may become two-lobed or two-
ridged, because it consists of two leaf-
margins, as Fig. 324; shows; it may
become 2-locellate by the turning or grow-
ing inward of one of the sutures, so as to
divide the cavity.

308. There are two or three terms which primarily relate to the parts
of a simple pistil or carpel, and are thence carried on to the compound
pistil, viz. : —

VENTRAL SUTURE, the line which answers to the united margins of the
carpel-leaf, therefore naturally called a suture or seam, and the ventral
or inner one, because in the circle of carpel-leaves it looks inward or to the
centre of the flower.

DORSAL SUTURE is the line down the back of the carpel, answering tc

FIG. 323. An inrolled small leaf, such as in double-flowered Cherry blossoms is
often seen to occupy the place of a pistil.

FIG. 324. A simple pistil (of Isopyrum), with ovary cut across ; the inner (ven«
tral) face turned toward the eye : the ovules seem to be borne on the ventral suture,

PISTILS.

107

the midrib of the leaf, — not a seam therefore ; but at maturity many fruits,
such as pea-pods, open by this dorsal as well as by the ventral line.

PLACENTA, a name given to the surface, whatever it be, which bears
the ovules and seeds. The name may be needless when the ovules grow
directly on the ventral suture, or from its top or bottom ; but when there
are many ovules there is usually some expansion of an ovule-bearing
or seed-bearing surface; as is seen in our Mandrake or Podophyllum,
Kg. 326.

309. A Compound Pistil is a combination of two, three, or a greater
number of pistil-leaves or carpels in a circle, united into one body, at least

by their ovaries. The annexed figures should make it clear. A series
of Saxifrages might be selected the gynoscium of which would show every
gradation between two simple pistils, or separate carpels, and their com-
plete coalescence into one compound and two-celled ovary. Even when
the constituent styles and stigmas are completely coalescent into one, the
nature of the combination is usually revealed by some external lines or
grooves, or (as in Fig. 328-330) by the internal partitions, or the number
of the placentae. The simplest case of compound pistil is that

310. With two or more Cells and Axile Placentae, namely, with as
many cells as there are carpels, that have united to compose the organ.

108

COMPOUND PISTILS.

[SECTION 10.

Such a pistil is just what would be formed if the simple pistils (two, three,

or five in a circle, as the case may be), like those of a Pseony or Stonecrop

(Fig. 224, 225), pressed together in the centre of the flower,

were to cohere by their contiguous parts. In such a case

the placentae are naturally axile, or all brought together in

the axis or centre ; and the ovary has as many DISSEPIMENTS,

or internal Partitions, as there are carpels in its composition.

For these are the contiguous and coalescent walls or sides of

the component carpels. When such pistils ripen into pods,

they often separate along these lines into their elementary

carpels.

311. One-celled, with free Central Placenta. The
commoner case is that of Purslane (Fig. 272) and of the
Pink and Chick weed families (Fig. 331, 332). This is ex-
plained by supposing that the partitions (such as those of
Fig. 329) have early vanished or have been suppressed. In-
deed, traces of them may often be detected in Pinks. On the other hand,
it is equally supposable that in the Primula family the free central is de
rived from parietal placentation by the carpels bearing ovules

only at base, and forming a consolidated common placenta
in the axis. Mitella and Dion&a help out this conception.

312. One-celled, with Parietal Placentae. In this not
uncommon case it is conceived that the two or three or
more carpel-leaves of such a compound pistil coalesce by
their adjacent edges, just as sepal-leaves do to form a gamo-

sepalous calyx,

or petak to f°rm

a gamopetalous
corolla, and as
is shown in the
diagram, Fig.
333, and in an
actual cross-sec-

tion, Fig. 334. Here each carpel is an open leaf, or with some introflexion,
bearing ovules along its margins ; and each placenta consists of the con

tiguous margins of two pistil-leaves grown together. There is every grada-
tion between this and the three-celled ovary with the placentae in the axis,
even in the same genus, sometimes even in different stages in the same
pistil (Fig. 335, 336).

§ 2. QYMNOSPEEMOUS GYNCECIUM.

313. The ordinary pistil has a closed ovary, and accordingly the pollen
can act upon the contained ovules only indirectly, through the stigma
This is expressed in a term of Greek derivation, viz. : —

Angiospermous, meaning that the seeds are borne in a sac or closed
vessel. The counterpart term is

Gymnospermous, meaning naked-seeded. This kind of pistil, or gyno>
cium, the simplest of all, yet the most peculiar, characterizes the Pine
family and its relatives.

814-. While the ordinary simple pistil is conceived by the botanist to
^M^ be a leaf rolled together into a closed pod (306), those of the
Pine, Larch (Fig. 337), Cedar, and Arbor-Vitse (Fig. 338,
339) are open leaves, iu the form of scales, each bearing two
or more ovules on the inner face, next the base. At the time
387 of blossoming, these pistil-leaves of the young cone diverge,
and the pollen, so abundantly shed from the stam-
inate blossoms, falls directly upon the exposed/
ovules. Afterward the scales close over each^
other until the seeds are ripe. Then they sepa-
rate that the seeds may be shed. As the pollen
acts directly on the ovules, such pistil (or organ
acting as pistil) has no stigma.

315. In the Yew, and in Torreya and Gingko,
the gynoecium is reduced to extremest simplicity,
that is, to -a naked ovule, without any visible
carpel.

316. In Cycas the large naked ovules are borne

on the margins or lobes of an obvious open leaf. All GYMNOSPERMOUS
plants have other peculiarities, also distinguishing them, as a class, from
ANGIOSPERMOUS plants.

110 OVULES. [SECTION 11

SECTION XL OVULES.

317. Ovule (from the Latin, meaning a little egg) is the technical name
of that which in the flower answers to and becomes the seed.

318. Ovules are naked in gymnospermous plants (as just described) ; iu
all others they are enclosed in the ovary. They may be produced along the

whole length of the cell or cells of the ovary, and then they are
apt to be numerous ; or only from some part of it, generally
' the top or the bottom. In this case tuey are usually few or
single (solitary •, as in Fig. 34)1-343). They may be sessile,
i. e. without stalk, or they may be attached by a distinct stalk,
340 the FUNICLE or FUNICULUS (Fig. 340).

319. Considered as to their position and direction in the ovary, they are
Horizontal, when they are neither turned upward nor downward, as in

Podopbyllum (Fig. 326) ;

Ascending^ when rising obliquely upwards, usually from the side of the
cell, not from its very base, as in the But-
tercup (Fig. 341), and the Purslane (Fig.
272);

Erect t when rising upright from the
very base of the cell, as in the Buck-
wheat (Fig. 342) ;

Pendulous, when hanging from the 341 342

side or from near the top, as in the Flax (Fig. 270) ; and

Suspended, when hanging perpendicularly from the very summit of the
cell, as in the Anemone (Fig. 343). All these terms equally apply to
seeds.

320. In structure an ovule is a pulpy mass of tissue, usually with one
or two coats or coverings. The following parts are to be noted ; viz : —

KERNEL or NUCLEUS, the body of the ovule. In the Mistletoe and some
related plants, there is only this nucleus, the coats being wanting.

TEGUMENTS, or coats, sometimes only one, more commonly two. When
two, one has been called PRIMINE, the other SECUNDINE. It will serve all
purposes to call them simply outer and inner ovule-coats.

ORIFICE, or FORAMEN, an opening through the coats at the organic apex
of the ovule. In the seed it is Micropyle.

CHALAZA, the place where the coats and the kernel of the ovule blend.

HILUM, the place of junction of the fnniculus with the body of the ovule.

321. The Kinds of Ovules. The ovules in their growth develop in
three or four different ways, and thereby are distinguished into

Orthotropous or Straight, those which develop without curving or turn-

ing, as in Fig. 344. The chalaza is at the insertion or base ; the foramen
or orifice is at the apex. This is the simplest, but the least common kind of
ovule.

Campylotropous or Incurved, in which, by the greater growth of one side,

the ovate curves into a kidney-shaped outline, so bringing the orifice down
close to the base or chalaza; as in Fig. 345.

Amphitropous or Half-Inverted, Fig. 346. Here
the forming ovule, instead of curving perceptibly,
keeps its axis nearly straight, and, as it grows, turns
round upon its base so far as to become transverse to
its funiculus, and adnate to its upper part for some
distance. Therefore in this case the attachment of
the funiculus or stalk is about the middle, the chal-
aza is at one end, the orifice at the other.

Anatropous or Inverted, as in Fig. 347, the com-
monest kind, so called because in its growth it has
as it were turned over upon its stalk, to which it has continued adnate.
The organic base, or chalaza, thus becomes the apparent summit, and the

orifice is at the base, by the side of the hilum or place of attachment. The
adnate portion of the funiculus, which appears as a ridge or cord extending
from the hilum to the chalaza, and which distinguishes this kind of ovule,
is called the RHAFHJS. The amphitropous ovule (Fig. 346) has a short or
incomplete rhaphe.

322. Tig. 348-352 show the stages through which an ovule becomes
anatropous in the course of its growth. The annexed two figures are sec-
tions of such an ovule at maturity ; and Fig. 355 is Fig. 353 enlarged,
with the parts lettered.

SECTION XII. MODIFICATIONS OF THE RECEPTACLE.

323. The Torus or Receptacle of the flower (237, Fig. 223) is the por-
tion which belongs to the stem or axis. In all preceding illustrations it is
small and short. But it sometimes lengthens, sometimes thickens or vari-
ously enlarges, and takes on various forms. Some of these have received
special names, very few of which are in common use. A lengthened por-
tion of the receptacle is called

A STIPE. This name, which means simply a trunk or stalk, is used in

botany for various stalks, even for the leaf-stalk in Ferns. It is also applied
to the stalk or petiole of a carpel, in the rare cases when there is any, as in

FIG. 356. Longitudinal section of flower of Silene Pennsylvania, showing stipe
between calyx and corolla.

FIG. 357. Flower of a Cleome of the section Gynandropsis, showing broadened
receptacle to bear petals, lengthened stipe below the stamens, and another between
these and pistil.

Goldthread. Then it is technically distinguished as a THECAPHOEE. When
there is a stalk, or lengthened internode of receptacle, directly under a
compound pistil, as in Stanleya and some other Cruciferse, it is called a
GYNOPHORE. When the stalk is developed below the stamens, as in most
species of Sileue (Fig. 356), it has been called an ANTHOPHORE or GONO-
PHORE. In Fig. 357 the torus is dilated above the calyx where it bears
the petals, then there is a long internode (gonophore) between it and the
stamens ; then a shorter one (gynophore) between these and the pistil.

324. A Carpophore is a prolongation of receptacle or axis between the
carpels and bearing them. Umbelliferous plants and Geranium (Fig. 358,
359) afford characteristic examples.

325. Flowers with very numerous simple pistils generally have the re-
ceptacle enlarged so as to give them room ; sometimes becoming broad and
flat, as in the Flowering Raspberry, sometimes elongated, as in the Black-

berry, the Magnolia, etc. It is the receptacle in the Strawberry (Fig. 360),
much enlarged and pulpy when ripe, which forms the eatable part of the
fruit, and bears the small seed-like pistils on its surface. In the Rose
(Fig. 361), instead of being convex or conical, the receptacle is deeply
concave, or urn-shaped. Indeed, a Rose-hip may be likened to a straw-
berry turned inside out, like the finger of a glove reversed,
and the whole covered by the adherent tube of the calyx.
The calyx remains beneath in the strawberry.

326. In Nelumbium, of the Water-Lily family, the singu-
lar and greatly enlarged receptacle is shaped like a top, and
bears the small pistils immersed in separate cavities of its flat '
upper surface (Fig. 362).

327. A Disk is an enlarged low receptacle or an out-
growth from it, hypogynous when underneath the pistil, as in
Rue and the Orange (Fig. 363), and perigynous when adnate

to calyx-tube (as in Buckthorn, Fig. 364, 365), and Cherry (Fig. 271), or

to both calyx-tube and ovary, as in Hawthorn (Fig. 273). A flattened

hypogyuous disk, underlying the ovary
or ovaries, and from which they fall
away at maturity, is sometimes called
a GYNOBASE, as in the Rue family.
In some Borragineous flowers, such as
Houndstongue, the gynobase runs up
in the centre between the carpels into

a carpophore. The so-called epigynous disk (or STYLOPODIUM) crowning

the summit of the ovary in flowers of Umbelliferse, etc., cannot be said to

belong to the receptacle.

SECTION XIII. FERTILIZATION.

328. The end of the flower is attained when the ovules become seeds.
A flower remains for a certain time (longer or shorter according to the
species) in anthesis, that is, in the proper state for the fulfilment of this
end. During anthesis, the ovules have to be fertilized by the pollen ; or at
Ibast some pollen has to reach the stigma, or in gymnospermy the ovule
itself, and to set up the peculiar growth upon its moist and permeable tis-
sue, which has for result the production of an embryo in the ovules. By
this the ovules are said to be fertilized. The first step is pollination, or,
so to say, the sowing of the proper pollen upon the stigma, where it is to
germinate.

§ 1. ADAPTATIONS FOR POLLINATION OF THE STIGMA.

329. These various and ever-interesting adaptations and processes are
illustrated in the "Botanical Text Book, Structural Botany," chap. VI.
sect, iv., also in a brief and simple way in " Botany for Young People, How
Plants Behave." So mere outlines only are given here.

330. Sometimes the application of pollen to the stigma is left to chance,
as in dioecious wind-fertilized flowers ; sometimes it is rendered very sure,
as in flowers that are fertilized in the bud ; sometimes the pollen is prevented
from reaching the stigma of the same flower, although placed very near to
it, but then there are always arrangements for its transference to the stigma
of some other blossom of the kind. It is among these last that the most
exquisite adaptations are met with.

331. Accordingly, some flowers are particularly adapted to close or self-
fertilization ; others to cross fertih'zation ; some for either, according to
circumstances.

FIQ. 365. Vertical section of same flower

SECTION 13.J FERTILIZATION. 115

Close Fertilization occurs when the pollen reaches and acts upon a stigma
of the very same flower (this is also called self-fertilization), or, less closely,
upon other blossoms of the same cluster or the same individual plant.

Cross Fertilization occurs when ovules are fertilized by pollen of other
individuals of the same species.

Hybridization occurs when ovules are fertilized by pollen of some other
(necessarily some nearly related) species.

332. Close Fertilization would seem to be the natural result in ordi-
nary hermaphrodite flowers ; but it is by no means so in all of them. More
commonly the arrangements are such that it takes place only after some
opportunity for cross fertilization has been afforded. But close fertiliza-
tion is inevitable in what are called

Cleistogamous Flowers, that is, in those which are fertilized in the flower-
bud, while still unopened. Most flowers of this kind, indeed, never open
at all ; but the closed floral coverings are forced off by the growth of the
precociously fertilized pistil. Common examples of this are found in the
earlier blossoms of Specularia perfoliata, in the later ones of most Violets, es-
pecially the stemless species, in our wild Jewel weeds or Impatiens, in the
subterranean shoots of Amphicarpsea. Every plant which produces these
cleistogamous or bud-fertilized flowers bears also more conspicuous and
open flowers, usually of bright colors. The latter very commonly fail to
set seed, but the former are prolific.

333. Cross Fertilization is naturally provided for in dioecious plants
(249), is much favored in monoecious plants (249), and hardly less so in
dichogamous and in heterogonous flowers (338). Cross fertilization depends
upon the transportation of pollen ; and the two principal agents of convey-
ance are winds and insects. Most flowers are in their whole structure
adapted either to the one or to the other.

334. Wind-fertilizable or Anemophilous flowers are more commonly
dioecious or monoecious, as in Pines and all coniferous trees, Oaks, and
Birches, and Sedges ; yet sometimes hermaphrodite, as in Plantains and
most Grasses ; they produce a superabundance of very light pollen, adapted
to be wind-borne; and they offer neither nectar to feed winged insects,
nor fragrance nor bright colors to attract them.

335. Insect-fertilizable or Entomophilous flowers are those which
are sought by insects, for pollen or for nectar, or for both. Through their
visits pollen is conveyed from one flower and from one plant to another.
Insects are attracted to such blossoms by their bright colors, or their fra-
grance, or by the nectar (the material of honey) there provided for them.
While supplying their own needs, they carry pollen from anthers to stigmas
and from plant to plant, thus bringing about a certain amount of cross fer-
tilization. Willows and some other dioecious flowers are so fertilized,
chiefly by bees. But most insect- visited flowers have the stamens and pis-
tils associated either in tke same or in contiguous blossoms. Even when
in the same blossom, anthers and stigmas are very commonly so situaW

116 FERTILIZATION. [SECTION 13.

that under insect-visitation, some pollen is more likely to be deposited upon
other than upon own stigmas, so giving a chance for cross as well as for
close fertilization. On the other hand, numerous flowers, of very various
kinds, have their parts so arranged that they must almost necessarily be cross-
fertilized or be barren, and are therefore dependent upon the aid of insects.
This aid is secured by different exquisite adaptations and contrivances,
which would need a volume for full illustration. Indeed, there is a good
number of volumes devoted to this subject.1

336. Some of the adaptations which favor or ensure cross fertilization
are peculiar to the particular kind of blossom. Orchids, Milkweeds, Kal-
mia, Iris, and papilionaceous flowers each have their own special contriv-
ances, quite different for each.

337. Irregular flowers (253) and especially irregular corollas are usu
ally adaptations to insect-visitation. *So are all Nectaries, whether hollow
spurs, sacs, or other concavities in which nectar is secreted, and all nectar-
iferous glands.

338. Moreover, there are two arrangements for cross fertilization com-
mon to hermaphrodite flowers in various different families of plants, which
have received special names, Dichogamy and Heterogony.

339. Dichogamy is the commoner case. Elowers are dichogamous when
the anthers discharge their pollen either before or after the stigmas of that
flower are in a condition to receive it. Such flowers are

Proterandrous, when the anthers are earlier than the stigmas, as in Gen-
tians, Campanula, Epilobium, etc.

Proterogynous, when the stigmas are mature and moistened for the re-
ception of pollen, before the anthers of that blossom are ready to supply
it, and are withered before that pollen can be supplied. Plantains or
Ribworts (mostly wind-fertilized) are strikingly proterogynous : so is Amor-
pha, our Papaws, Scrophularia, and in a less degree the blossom of Pears,
Hawthorns, and Horse-chestnut.

340. In Sabbatia, the large-flowered species of Epilobium, and strikingly
in Clerodendron, the dichogamy is supplemented and perfected by move-
ments of the stamens and style, one or both, adjusted to make sure of
cross fertilization.

341. Heterogony. This is the case in which hermaphrodite and fer-
tile flowers of two sorts are produced on different individuals of the same
species ; one sort having higher anthers and lower stigmas, the other hav-
ing higher stigmas and lower anthers. Thus reciprocally disposed, a visit-
ing insect carries pollen from the high anthers of the one to the high stigma
of the other, and from the low anthers of the one to the low stigma of the
other. These plants are practically as if dioecious, with the advantage that

Darwin, " On the Various Contrivances by which Orchids are fertilized ty Insects,"
*nd in succeeding works.

SECTION 14.] FRUIT. 117

both kinds are fruitful. Houstonia and Mitchella, or Partridge-berry, are
excellent and familiar examples. These are cases of

Heterogone Dimorphism, the relative lengths being only short and long
reciprocally.

Heterogone Trimorphism, in which there is a mid-length as well as a long
and a short set of stamens and style; occurs in Lythruin Salicaria and some
species of Oxalis.

342. There must be some essential advantage in cross fertilization or
cross breeding. Otherwise all these various, elaborate, and exquisitely
adjusted adaptations would be aimless. Doubtless the. advantage is the
same as that which is realized in all the higher animals by the distinction
of sexes.

§ 2. ACTION OF POLLEN, AND FORMATION OF THE EMBRYO.

343. Pollen-growth. A grain of pollen may be justly likened to one
of the simple bodies (spores) which answer for seeds in Cryptogamous plants.
Like one of these, it is capable of germination. When deposited upon the
moist surface of the stigma (or in some cases even when at a certain dis-
tance) it grows from some point, its living inner coat breaking through the
inert outer coat, and protruding in the form of a delicate tube. This as it
lengthens penetrates the loose tissue of the stigma and of a loose conduct-
ing tissue in the style, feeds upon the nourishing liquid matter there pro-
vided, reaches the cavity of the ovary, enters the orifice of an ovule, and
attaches its extremity to a sac, or the lining of a definite cavity, in the
ovule, called the Embryo-Sac.

344. Origination of the Embryo. A globule of living matter in the
embryo-sac is formed, and is in some way placed in close proximity to the
apex of the pollen tube ; it probably absorbs the contents of the latter ; it
then sets up a special growth, and the Embryo (8-10) or rudimentary
plantlet in the seed is the result.

SECTION XIV. THE FRUIT.

345. Its Nature. The ovary matures into the Fruit. In the strictest
sense the fruit is the seed-vessel, technically named the PERICARP. But
practically it may include other parts organically connected with the peri-
carp. Especially the calyx, or a part of it, is often incorporated with the
ovary, so as to be undistinguishably a portion of the pericarp, and it even
forms along with the receptacle the whole bulk of such edible fruits as
apples and pears. The receptacle is an obvious part in blackberries, and
is the whole edible portion in the strawberry.

346. Also a cluster of distinct carpels may, in ripening, be consolidated
or compacted, so as practically to be taken for one fruit. Such are raspber-

118

FRUIT.

[SECTION 14,

ries, blackberries, the Magnolia fruit, etc. Moreover, the ripened product
of many flowers may be compacted or grown together so as to form a single
compound fruit.

347. Its kinds have therefore to be distinguished. Also various names
of common use in descriptive botany have to be mentioned and defined.

348. In respect to composition, accordingly, fruits may be classified
into

Simple, those which result from the ripening of a single pistil, and con-
sist only of the matured ovary, either by itself, as in a cherry, or with
calyx-tube completely incorporated with it, as in a gooseberry or cranberry.
Aggregate, when a cluster of carpels of the same flower are crowded into
a mass ; as in raspberries and blackberries.

Accessory or Anthocarpons, when the surroundings or supports of the
pistil make up a part of the mass ; as does
the loose calyx changed into a fleshy and
berry-like envelope of our Wintergreen
(Gaultheria, Fig. 366, 367) and Buffalo-
berry, which are otherwise simple fruits.
In an aggregate fruit such as the straw-
berry the great mass is receptacle (Fig.
360, 368) ; and hi the blackberry (Fig. 369) the juicy receptacle forms the
central part of the savory mass.

Multiple or Collective, when formed from several flowers consolidated
into one mass, of which the common
receptacle or axis of inflorescence,
$$/ the floral envelopes, and even the
bracts, etc., make a part. A mul-
berry (Fig. 408, which superficially
much resembles a
blackberry) is of this
multiple sort. Apine-
apple is another ex-
ample.

349. In respect to
texture or consist-
ence, fruit* may be
distinguished into three kinds, viz. : —

Meshy Fruits, those which are more or less soft and juicy throughout ;

119

Stone Fruits, or Drupaceous, the outer part fleshy like a berry, the inner
hard or stony, like a nut ; and

Dry Fruits, those which have no flesh or pulp.

350. In reference to the way of disseminating the contained seed, fruits
are said to be

Indehiscent when they do not open at maturity. Fleshy fruits and stone
fruits are of course indehiscent. The seed becomes free only through
decay or by being fed upon by animals. Those which escape digestion are
thus disseminated by the latter. Of dry fruits many are indehiscent ; and
these are variously arranged to be transported by animals. Some burst
irregularly; many are

Dehiscent, that is, they split open regularly along certain lines, and
discharge the seeds. A dehiscent fruit almost always contains many or
several seeds, or at least more than one seed.

871 372 373 374

351. The principal kinds of fruit which have received substantive names
and are of common use in descriptive botany are the following. Of fleshy
fruits the leading kind is

352. The Berry, such as the gooseoerry and currant, the blueberry
and cranberry (Fig. 371), the tomato, and the grape. Here the whole
flesh is soft throughout. The orange is a berry with a leathery rind.

353. The Pepo, or Gourd-fruit, is a hard-rinded berry, belonging to
the Gourd family, such as the pumpkin, squash, cucumber, and melon,
Fig. 372, 373.

354. The Pome is a name applied to the apple, pear (Fig. 374), and
quince ; fleshy fruits, like a berry, but the principal thickness is calyx, only

the papery pods arranged like a star in the core really belonging to the
carpels. The fruit of the Hawthorn is a drupaceous pome, something be-
tween pome and drupe.

355. Of fruits which are externally fleshy and internally hard the lead-
ing kind is

356. The Drupe, or Stone-fruit ; of which the cherry, plum, and peach

(Pig. 375) are familiar examples. In this the
outer part of the thickness of the pericarp be-
comes fleshy, or softens like a berry, while the
inner hardens, like a nut. From the way in which
the pistil is constructed, it is evident that the
fleshy part here answers to the lower, and the
stone to the upper face of the component leaf.
The layers or concentric portions of a drupe, or
of any pericarp which is thus separable, are named,
when thus distinguishable into three portions, —
Epicarp, the external layer, often the mere skin of the fruit,
Mesocarp, the middle layer, which is commonly the fleshy part, and
Endocarp, the innermost layer; the stone. But more commonly only two
portions of a drupe are distinguished, and are named, the outer one

Sarcocarp or Exocarp, for the flesh, the first name referring to the fleshy
character, the second to its being an external layer ; and
Putamen or Endocarp, the Stone, within.

357. The typical or true drupe is of a single carpel. But, not to multiply
technical names, this name is extended to all such fruits when

fleshy without and stony within, although of compound pistil,
— even to those having several or separable stones, such as the
fruit of Holly. These stones in such drupes, or drupaceous
fruits, are called Pyren<B> or Nucules, or simply Nutlets of
the drupe.

358. Of Dry fruits, there is a greater diversity of kinds hav-
ing disiinct names. The indehis-

cent sorts are commonly one-

359. The Akene or Ache-
nium is a small, dry and indehis-
cent one-seeded fruit, often so
seed-like in appearance that it is
popularly taken for a naked seed.

case a simple carpel), is apparent by its bearing the remains of a style or
stigma, or a scar from which this has fallen. It may retain the style and
use it in various ways for dissemination (Fig. 378).

360. The fruit of Composite (though not of a single carpel) is also an
akene. In this case the pericarp is invested
by an adherent calyx-tube ; the limb of which,
when it has any, is called the PAPPUS. This
name was first given to the down like that of \
the Thistle, but is applied to all forms under
which the limb of the calyx of the " compound
flower " appears. In Lettuce, Dandelion (Pig.

384), and the like, the achenium as it matures tapers upwards into a slendei

beak, like a stalk to the pappus.

361. A Cremocarp (Fig. 385), a name given to the fruit of Umbelli
fera3, consists as it were of a pair of akenes united com-
pletely in the blossom, but splitting apart when ripe (
into the two closed carpels. Each of these is a Meri-
carp or Hemicarp, names seldom used.

362. A Utricle is the same as an akene, but with
a thin and bladdery loose pericarp; like that of the
Goosefoot or Pigweed (Fig. 386). When ripe it may
burst open irregularly to discharge the seed ; .or it may
open by a circular line all round, the upper part fall-
ing off like a lid ; as in the Amaranth (Fig. 387).

363. A Caryopsis, or Grain, is like an akeue with
the seed adhering to the thin pericarp throughout, so

that fruit and seed are incorporated into one body ; as in wheat, Indian
corn, and other kinds of grain.
364. A Nut is a dry and indehiscent fruit, commonly one-celled and one.

involucre, in the form of a cup at the base, is called the
CUPULE. In the Chestnut the cupule forms the bur; in
the Hazel, a leafy husk.

365. A Samara, or Key-fruit, is either a nut or an
akene, or any other iudehiscent fruit, furnished with a wing,
like that of Ash (Fig. 389), and Elm (Fig. 390). The
Maple-fruit is a pair of keys (Fig. 391).

366. Dehiscent Fruits, or Pods, are of two classes, viz.,
those of a simple pistil or carpel, and those of a compound

pistil. Two common sorts of the first are named as follows : —

367. The Follicle is a fruit of a simple carpel, which dehisces down one
side only, i. e. by the inner or ventral suture. The i

and Milkweed are of this kind.

368. The Legume or true Pod, such as the peapod \
(Fig. 393), and the fruit of the Leguminous or Pulse
family generally, is one which opens along the dorsal as

well as the ventral suture. The two pieces

into which it splits are called VALVES. A LOMENT is a legume which is
constricted between the seeds, and at length breaks up crosswise into dis-
tinct joints, as in Fig. 394.

369. The pods or dehiscent fruits belonging to a compound ovary have
several technical names : but they all may be regarded as kinds of

370. The Capsule, the dry and dehiscent fruit of any compound pistil.
The capsule may discharge its seeds through chinks or pores, as in the

Poppy, or burst irregularly in some part, as in Lobelia and the Snapdragon ;
but commonly it splits open (or is dehiscent) lengthwise into regular pieces,
called VALVES

371. Regular Dehiscence in a capsule takes place in two ways, which are
best illustrated in pods of two or three cells. It is either

Loculicidal, or, splitting directly into the loculi or cells, that is, down
the back (or the dorsal suture) of each cell or carpel, as in
Iris (Fig. 395) ; or

Septicidal, that is, splitting through the partitions or septa,
as in St. Jolm's-wort (Fig. 396), Rhododendron,
etc. This divides the capsule into its compo-
nent carpels, which then open by their ventral
suture.

372. In loculicidal dehiscence the valves nat-
urally bear the partitions on their middle ; in
the septicidal, half the thickness of a partition
is borne on the margin of each valve. See the
annexed diagrams. A variation of either mode
occurs when the valves break away from the
partitions, these remaining attached in the axis of
the fruit. This is caPed Septifragal deliiscence.
One form is seen in the Morning-Glory (Fig.
400).

373. The capsules of Rue, Spurge, and some others, are both loculi
cidal and septicidal, and so split ^

into half-carpellary valves or pieces, f

FRUIT.

[SECTION 14.

376. The Pyxis is a pod which opens by a circular horizontal Hue, the
upper part forming a lid, as in Purslane (Fig. 404), the Plantain, Hen-
bane, etc. In these the dehiscence extends all round, or is cir-
cumscissile. So it does in Amaranth (Fig. 387), forming a one-
seeded utricular pyxis. In Jeffersouia, the line does not separate
quite round, but leaves a portion for a hinge to the lid.

377. Of Multiple or Collective Fruits, which are properly
masses of fruits aggregated
into one body (as is seen in
the Mulberry (Fig. 408), Pine-
apple, etc.), there are two kinds
with special names and of pe-
culiar structure.

378. The Syconium or Fig-

402 404 fruit (Fig. 405, 406) is a fleshy

axis or summit of stem, hollowed out, and lined within by a multitude of
minute flowers, the whole becoming pulpy, and in the common fig, luscious,

379. The Strobile or Cone (Fig. 411), is the peculiar multiple fruit
of Pines, Cypresses, and the like: hence named Conifera, viz. cone-bearing

plants. As already shown (313), these cones are open pistils, mostly in
the form of flat scales, regularly overlying each
other, and pressed together in a spike or head.
Each scale bears one or two naked seeds on its
inner face. When ripe and dry, the scales turn
back or diverge, and in the Pine the seed peels
off and falls, generally carrying with it a wing, a
part of the lining of the scale,
which facilitates the disper-
sion of the seeds by the wind
(Fig. 412, 413). In Arbor-
Vitse, the scales of the small

cone are few, and not very
unlike the leaves. In Cy-
press they are very thick at
the top and narrow at the

base, so as to make a peculiar sort of closed cone. In Jumper and Red
Cedar, the few scales of the very small cone become fleshy, and ripen into
a fruit which closely resembles a berry.

SECTION XV. THE SEED.

380. Seeds are the final product of the flower, to which all its parts and
offices are subservient. Like the ovule from which it originates, a seed
consists of coats and kernel.

381. The Seed-coats are commonly two (320), the outer and the inner.
Fig. 414 shows the two, in a seed cut through lengthwise. . _

The outer coat is often hard or crustaceous, whence it is
called the Testa, or shell of the seed ; the inner is almost al-
ways thin and delicate.

382. The shape and the markings, so various in different
seeds, depend mostly on the outer coat. Sometimes this fits

the kernel closely ; sometimes it is expanded into a wing, as in the Trum-
pet-Creeper (Fig. 415), and occasionally this wing is cut up into shreds
or tufts, as in the Catalpa (Fig. 416) ; or instead of a wing it may bear a
Coma, or tuft of long and soft hairs, as in the Milkweed or Silkweed (Fig.
417). The use of wings, or downy tufts is to render the seeds buoyant

SEEDS.

[SECTION 18.

for dispersion by the winds. This i» clear, not only from their evident
adaptation to this purpose, but also from the fact that winged and tufted
seeds are found only in fruits that split open at maturity, never in those
that remain closed. The coat of some seeds is beset with
long hairs or wool. Cotton, one of the most important vege-
table products, since it forms the principal clothing of the

larger part of the human race, consists of the long and woolly hairs which
thickly cover the whole surface of the seed. There are also crests or other
appendages of various sorts on certain seeds. A few seeds
have an additional, but more or less incomplete covering, out-
side of the real seed-coats called an

383. Aril, or Arillus. The loose and transparent
bag which encloses the seed of the White Water-Lily
(Fig. 418) is of this kind. So is the mace of the
nutmeg ; and also the scarlet pulp around the seeds
of the Waxwork (Celastrus) and Strawberry-bush
(Euonymus). The aril is a growth from the ex-
tremity of the seed-stalk, or from the placenta when
there is no seed-stalk.

384. A short and thickish appendage at or close to the hilum in certain
seeds is called a CARUNCLE or STROPHIOLE (Fig. 419).

385. The various terms which define the position or direc-
tion of the ovule (erect, ascending, etc.) apply equally to the
seed : so also the terms anatropous, orthotropous, campylotro-
pous, etc., as already defined (320, 321), and such terms as

HILUM, or Scar left where the seed-stalk or funiculus falls
away, or where the seed was attached directly to the placenta
when there is no seed-stalk. 419

RHAPHE, the line or ridge which runs from the hilum to the chalaza in
anatropous and amphitropous seeds.

CHALAZA, the place where the seed-coats and the kernel or nucleus are
organically connected, — at the hilum in orthotropous and campylotropous
seeds, at the extremity of the rhaphe or tip of the seed in other kinds.

SECTION 15.] EMBRYO. 127

386. The Kernel, or Nucleus, is the whole body of the seed within the

coats. Iii many seeds the ker-
nel is all Embryo ; in others
a large part of it is the Al-
bumen. For example, in Fig.
423, it is wholly embryo; in

Fig. 422, all but the small 420 428 421 ~422

speck (^) is albumen.

387. The Albumen or Endosperm of the seed is sufficiently charac-
terized and its office explained in Sect. III., 31-35.

388. The Embryo or Germ, which is the rudimentary plantlet and the
final result of blossoming, and its development in germination have been
extensively illustrated in Sections II. and III. Its essential parts are the
Radicle and the Cotyledons.

389. Its Radicle or Caulicle (the former is the term long and gener-
ally used in botanical descriptions, but the latter is the more correct one,
for it is the initial stem, which merely gives origin to the root), as to its
position in the seed, always points to and lies near the micropyle. In re-
lation to the pericarp it is

Superior, when it points to the apex of the fruit or cell, and
Inferior, when it points to its base, or downward.

390. The Cotyledons have already been illustrated as re-
spects their number, — giving the important distinction of Dicoty-
ledonous, Polycotyledonous and Monocotyledonous embryos (36-43),
— also as regards their thickness, whether foliaceous or fleshy ;

and some of the very various shapes and adaptations to the seed have been
figured. They may be straight, or folded, or rolled up. In the latter
case the cotyledons may be rolled up as it were from one margin, as
in Calycanthus (Fig. 424), or from apex to base in
a flat spiral, or they may be both folded (plicate)
and rolled up (convolute), as in Sugar Maple (Fig.
11.) In one very natural family, the Cruciferse, two
different modes prevail in the way the two cotyledons
are brought round against the radicle. In one series
425 426 they are

128 VEGETABLE LIFE AND WORK, [SECTION 16.

Accumbent, that is, the edges of the flat cotyledons lie against the radicle,
as in Fig. 425, 426. In another they are

Incumbent, or with the plane of the cotyledons brought up in the opposite
direction, so that the back of one of them lies against
the radicle, as shown in Fig. 427, 428.

391. As to the situation of the embryo with respect
to the albumen of the seed, when this is present in any
quantity, the embryo may be Axile, that is occupying
427 428 the axis or centre, either for most of its length, as iu

Violet (Fig. 429), Barberry (.Fig. 48), and
Pine (Fig. 56) ; and in these it is straight.
But it may be variously curved or coiled
in the albumen, as in Helianthemum
(Fig. 430), in a Potato-seed (Fig. 50),
or Onion-seed (Fig. 60), and Linden
(Fig. 414) ; or it may be coiled around 429 430 430 a

the outside of the albumen, partly or into a circle, as in Chickweed (Fig.
431, 432) and in Mirabilis (Fig. 52). The latter mode prevails in Campy lo-
tropous seeds. In the cereal grains, such as Indian
Corn (Fig. 67) and Rice, 430 «), and in all other
Grasses, the embryo is straight and applied to the
"UsST outside of the abundant albumen.
392. The matured seed, with embryo ready to germinate and reproduce
the kind, completes the cycle of the vegetable life in a phanerogamous
plant, the account of which began with the seed and seedling.

of the beings which compose so large a part of organic nature. Those who

Physiological Botany of the " Botanical Text Book," by Professor Goodale,
or some similar book.

SECTION 16.1 STRUCTURE AND GROWTH. 129

$ 1. ANATOMICAL STRUCTURE AND GROWTH.

394. Growth is the increase of a living thing in size and substance* It
appears so natural that plants and animals should grow, that one rarely
thinks of it as requiring explanation. It seems enough to say that a thing
is so because it grew so. Growth from the seed, the germination and de-
velopment of an embryo into a plantlet, and at length into a mature plant
(as illustrated in Sections II. and III.), can be followed by ordinary obser-
vation. But the embryo is already a miniature plantlet, sometimes with
hardly any visible distinction of parts, but often one which has already
made very considerable growth in the seed. To investigate the formation
and growth of the embryo itself requires well-trained eyes and hands, and
the expert use of a good compound microscope. So this is beyond the
reach of a beginner.

395. Moreover, although observation may show that a seedling, weigh-
ing only two or three grains, may double its bulk and weight every week
of its early growth, and may in time produce a huge amount of vegetable
matter, it is still to be asked what this vegetable matter is, where it came
from, and by what means plants are able to increase and accumulate it, and
build it up into the fabric of herbs and shrubs and lofty trees.

396. Protoplasm. All this fabric was built up under life, but only a
small portion of it is at any one time alive. As growth proceeds, life is
passed on from the old to the' new parts, much as it has passed on from
parent to offspring, from generation to generation in unbroken continuity.
Protoplasm is the common name of that plant-stuff in which life essentially
resides. All growth depends upon it; for it has the peculiar power of
growing and multiplying and building up a living structure, — the animal
no less than the vegetable structure, for it is essentially the same in both.
Indeed, all the animal protoplasm comes primarily from the vegetable,
which has the prerogative of producing it ; and the protoplasm of plants
furnishes all that portion of the food of animals which forms their flesh
and living fabric.

397. The very simplest plants (if such may specifically be called plants
rather than animals, or one may say, the simplest living things) are mere
particles, or pellets, or threads, or even indefinite masses of protoplasm of
vague form, which possess powers of motion or of changing their shape,
of imbibing water, air, and even other matters, and of assimilating these
into plant-stuff for their own growth and multiplication. Their growth
is increase in substance by incorporation of that which they take in and
assimilate. Their multiplication is by spontaneous division of their sub-
stance or body into two or more, each capable of continuing the process.

398. The embryo of a phanerogamous plant at its beginning (344) is es»
sentially such a globule of protoplasm, which soon constricts itself into two
and more such globules, which hold together inseparably in a row ; then
the last of the row divides without separation in the two other planes, to

130

VEGETABLE LIFE AND WORK. [SECTION 16.

433

form a compound mass, each grain or globule of which goes on to double
itself as it grows ; and the definite shaping of this still increasing mass
builds up the embryo into its form.

399. Cell- walls. While this growth was going on, each grain of the
forming structure formed and clothed itself with a coat, thin and trans-
parent, of something different from protoplasm, — something which hardly
^•^ and only transiently, if at all, partakes of the life and action.
The protoplasm forms the living organism ; the coat is a kind
of protective covering or shell. The protoplasm, like the
flesh of animals which it gives rise to, is composed of four
chemical elements: Carbon, Hydrogen, Oxygen, and Nitro-
gen. The coating is of the nature of wood (is, indeed, that
which makes wood), and has only the three elements, Car-
bon, Hydrogen, and Oxygen, in its composition.

400. Although the forming structure of an embryo in
the fertilized ovule is very minute and difficult to see, there
are many simple plants of lowest grade, abounding in pools
of water, which more readily show the earlier stages or sim-
plest states of plant-growth. One of these, which is common
in early spring, requires only moderate magnifying power
to bring to view what is shown in Tig. 437. In a slimy
mass which holds all loosely together, little spheres of green
vegetable matter are seen, assembled in fours,
and these fours themselves in clusters of fours.
A transient inspection shows, what prolonged
watching would confirm, that each sphere di-
vides first in one plane, then in the other, to
make four, soon acquiring the size of the original, and so on,
producing successive groups of fours. These pellets each
form on their surface a transparent wall, like that just des-
cribed. The delicate wall is for some time capable of expan-
sive growth, but is from the first much firmer than the
protoplasm within; through it the latter imbibes sur-
rounding moisture, which becomes a watery sap, occupy-
ing vacuities in the protoplasmic mass which enlarge or
run together as the periphery increases and distends.
When full grown the protoplasm may become a mere lining
to the wall, or some of it central, as a nucleus, this usually connected with
the wall-lining by delicate threads of the same substance. So, when full
grown, the wall with its lining — a vesicle, containing liquid or some

solid matters and in age mos^y air — naturally came to be named a CELL.
Bat the name was suggested by, and first used only for, cells in combination
or built up into a fabric, much as a wall is built of bricks, that is, into a

401. Cellular Structure or Tissue. Suppose numerous cells like
those of Fig. 437 to be heaped up like a pile of cannon-balls, and as they
grew, to be compacted together while soft and yielding ; they would flatten
where they touched, and each sphere,
being touched by twelve surrounding
ones would become twelve-sided. Kg.
438 would represent one of them.
Suppose the contiguous faces to be
united into one wall or partition be-
tween adjacent cavities, and a cellular
structure would be formed, like that
shown in Fig. 439. Roots, stems, leaves,
and the whole of phan-
erogamous plants are a
fabric of countless num-
bers of such cells. No
such exact regularity in
size and shape is ever
actually found ; but a nearly truthful magnified view of a small portion of
a slice of the flower-stalk of a Calla Lily (Fig. 440) shows a fairly corres-

ponding structure ; except that, owing to the great air-spaces of the interior,
the fabric may be likened rather to a stack of chimneys than to a solid
fabric. In young and partly transparent parts one may discern the cel-
lular structure by looking down directly on the surface, as of a form-
ing root. (Fig. 82, 441, 442).

402. The substance of which cell-walls are mainly composed is called
CELLULOSE. It is essentially the same in the stem of a delicate leaf or
petal and in the wood of an Oak, except that in the latter the walls are

much thickened and the calibre small. The protoplasm of each living cell
appears to be completely shut up and isolated in its shell of cellulose ; but
microscopic investigation has brought to view, in many cases, minute
threads of protoplasm which here and there traverse
the cell-wall through minute pores, thus connecting
the living portion of one cell with that of adjacent
cells. (See Fig. 447, &c.)

403. The hairs of plants are cells formed on the
surface ; either elongated single cells
(like the root-hairs of Fig. 441, 442),
or a row of shorter cells. Cotton
fibres are long and simple cells grow-
ing from the surface of the seed.

404. The size of the cells of which
common plants are made up varies
from about the thirtieth to the thou-
sandth of an inch in diameter. An
ordinary size of short or roundish
cells is from -g^y to yj-j- of an inch ; so that there may generally be from
27 to 125 millions of cells in the compass of a cubic inch !

405. Some parts are built up as a compact structure ; in others cells
are arranged so as to build up regular air-

channels, as in the stems of aquatic and other
water-loving plants (Fig. 440), or to leave
irregular spaces, as in the lower part of most
leaves, where the cells only here and there
come into close contact (Fig. 443).

406. All such soft cellular tissue, like
this of leaves, that of pith, and of the green
bark, is called PARENCHYMA, while fibrous
and woody parts are composed of PBOSEN-
CHYMA, that is, of peculiarly transformed

407. Strengthening Cells. Common cellular tissue, which makes UT>
the whole structure of all very young plants, and the whole of Mosses
and other vegetables of the lowest grade, even when full grown, is too
tender or too brittle to give needful strength and toughness for plants
which are to rise to any considerable height and support themselves. In
these needful strength is imparted, and the conveyance of sap through the
plant is facilitated, by the change, as they are formed, of some cells into
thicker-walled and tougher tubes, and by the running together of some of

these, or the prolongation of others, into hollow fibres or tubes of various size.
Two sorts of such transformed cells go together, and essentially form the

408. Wood. This is found in all common herbs, as well as in shrubs
and trees, but the former have much less of it in proportion to the softer
cellular tissue. It is formed very early in the growth of the root, stem,
and leaves, — traces of it appearing in large embryos even while yet in the
seed. Those cells that lengthen, and at the same time thicken their walls
form the proper WOODY FIBRE or WOOD-CELLS ; those of larger size and
thinner walls, which are thickened only in certain parts so as to have
peculiar markings, and which often are seen 444 445 447

to be made up of a row of cylindrical cells, f\
with the partitions between absorbed or bro-
ken away, are called DUCTS, or sometimes
VESSELS. There are all gradations between
wood-cells and ducts, and between both these
and common cells. But in most plants the
three kinds are fairly distinct.

409. The proper cellular tissne, or paren-
chyma, is the ground-work of root, stem, and
leaves ; this is traversed, chiefly lengthwise,
by the strengthening and conducting tissue,
wood-cells and duct-cells, in the form of
bundles or threads, which, in the stems and
stalks of herbs are fewer and comparatively
scattered, but in shrubs and trees so numer-
rous and crowded that in the stems and
all permanent parts they make a solid mass
of w ood. They extend into and ramify in
the leaves, spreading out in a horizontal
plane, as the framework of ribs and veins,
which supports the softer cellular portion or
parenchyma,

410. Wood-Cells, or Woody Fibres,
consist of tubes, commonly between one and

two thousandths, but in Pine-wood sometimes two or three hnndredths,
of an inch in diameter. Those from the tough bark of the Basswood,

shown in Fig. 444, are only the fifteen-hundredth of an inch wide. Thosa
of Buttonwood (Fig. 447) are larger, and are here highly magnified besides.
The figures show the way wood-cells are commonly put together, namely,
with their tapering ends overlapping each other, — spliced together, as it
were, — thus giving more strength and toughness. In hard woods, such
as Hickory and Oak, the walls of these tubes are very thick, as well as
dense ; while in soft woods, such as White-Pine and Basswood, they are
thinner.

411. Wood-cells in the bark are generally longer, finer, and tougher
than those of the proper wood, and appear more like fibres. For example,
Fig. 446 represents a cell of the wood of Basswood of average length, and
Fig. 444 one (and part of another) of the fibrous bark, both drawn to the
same scale. As these long cells form the principal part of fibrous bark, or
bast, they are named Bast-cells or Bast-fibres. These give the great tough-
ness and flexibility to the inner bark of Basswood (i. e. Bast-wood) and of
Leatherwood; and they furnish the invaluable fibres of flax and hemp;

the proper wood of their stems
being tender, brittle, and de-
stroyed by the processes which
separate for use the tough and
slender bast-cells. In Leather-
wood (Dirca) the bast-cells are
remarkably slender. A view of
one, if magnified on the scale
of Fig. 444, would be a foot
and a half long.
412. The wood-cells of Pines,

A

449

and more or less of all other Coniferous trees, have on two of their sides
very peculiar disk-shaped markings (Fig. 448-450) by which that kind cf
wood is recognizable.

413. Ducts, also called VESSELS, are mostly larger
than wood-cells : indeed, some of them, as in Red Oak,
have calibre large enough to be discerned on a cross
section by the naked eye. They make the visible porosity
of such kinds of wood. This is particularly the case with

Dotted ducts (Fig. 451, 452), the surface of which
appears as if riddled with round or oval pores. Such
ducts are commonly made up of a row of large cells more
or less confluent into a tube.

Scalariform ducts (Fig. 458, 459), common in Ferns,
and generally angled by mutual pressure in the bundles,

have transversely elongated thin places, parallel with each other, giving
a ladder-like appearance, whence the name.

Annular ducts (Fig. 457) are marked with cross lines or rings, which
are thickened portions of the cell-wall.

466 457

Spiral ducts or vessels (Pig. 453-455) have thin walls, strengthened by
a spiral fibre adherent within. This is as delicate and as strong as spider-
web : when uncoiled by pulling apart,
it tears up and annihilates the cell-
wall. The uncoiled threads are seen
by gently pulling apart many leaves,
such as those of Amaryllis, or the
stalk of a Strawberry leaflet.

Laticiferous ducts, Vessels of the
Latex, or Milk-vessels are peculiar
branching tubes which hold latex or
milky juice in certain plants. It is
very difficult to see them, and more
so to make out their nature. They
are peculiar in branching and inosculating, so as to make a net-work of
tubes, running in among the cellular tissue; and they are very small,
except when gorged and old (Fig. 460, 461).

136 VEGETABLE LIFE AND GROWTH. [SECTION 16.

| 2. CELL-CONTENTS.

414;. The living contents of young and active cells are mainly protoplasm
with water or watery sap which this has imbibed. Old and effete cells are
often empty of solid matter, containing only water with whatever may be
dissolved in it, or air, according to the time and circumstances. All the
various products which plants in general elaborate, or which particular
plants specially elaborate, out of the common food which they derive from
the soil and the air, are contained in the cells, and in the cells they are
produced.

415. Sap is a general name for the principal liquid contents, — Crude sap,
for that which the plant takes in, Elaborated sap for what it has digested or
assimilated. They must be undistinguishably mixed in the cells.

416. Among the solid matters into which cells convert some of their
elaborated sap two are general and most important. These are Chlorophyll
and Starch.

417. Chlorophyll (meaning leaf-green) is what gives the green color to
herbage. It consists of soft grains of rather complex nature, partly wax-
like, partly protoplasmic. These abound in the cells of all common leaves
and the green rind of plants, wherever exposed to the light. The green
oolor is seen through the transparent skin of the leaf and the walls of the
containing cells. Chlorophyll is essential to ordinary assimilation in plants :
by its means, under the influence of sunlight, the plant converts crude sap
into vegetable matter.

418. Far the largest part of all vegetable matter produced is that which
goes to build up the plant's fabric or cellular structure, either directly or
indirectly. There is no one good name for this most important product of
vegetation. In its final state of cell-walls, the permanent fabric of herb
and shrub and tree, it is called Cellulose (408) : in its most soluble form
it is Sugar of one or another kind ; in a less soluble form it is Dextrine, a
kind of liquefied starch : in the form of solid grains stored up in the cells
it is Starch. By a series of slight chemical changes (mainly a variation in
the water entering into the composition), one of these forms is converted
into another.

419. Starch (Farina or Fecula) is the form in which this common plant
material is, as it were, laid by for future use. It consists of solid grains,
somewhat different in form in different plants, in size varying from -^ to
^^ of an inch, partly translucent when wet, and of a pearly lustre. From
the concentric lines, which commonly appear under the microscope, the
grains seem to be made up of layer over layer. When loose they are com-
monly oval, as in potato-starch (Fig. 462) : when much compacted the
grains may become angular (Fig. 463).

420. The starch in a potato was produced in the foliage. In the soluble
form of dextrine, or that of sugar, it was conveyed through the cells of the
herbage and stalks to a subterranean shoot, and there stored up in the

SECTION 16.)

CELL-CONTENTS.

137

tuber. "When the potato sprouts, the starch in the vicinity of developing

buds or eyes is changed back again, first into mucilaginous dextrine, then

into sugar, dissolved

in the sap, and in this

form it is made to

flow to the growing

parts, where it is laid

down into cellulose

or cell-wall.

421. Besides these cell-contents which are in obvious and essential rela-
tion to nutrition, there are others the use of which is problematical. Of
such the commonest are

422. Crystals. These when slender or needle-shaped are called
RHAPHIDES. They are of inorganic matter, usually of oxalate or phosphate
or sulphate of lime. Some, at least of the latter, may be direct crystalliza^

tions of what is taken in dissolved in the water absorbed, but others must
be the result of some elaboration in the plant. Some plants have hardly
any ; others abound in them, especially in the foliage and bark. In Locust-
bark almost every cell holds a crystal ; so that in a square inch not thicker
than writing-paper there may be over a million and a half of them. When

needle-shaped (rhaphides), as in stalks of Calla-Lily, Rhubarb, or Four-

| 3. ANATOMY OF ROOTS AND STEMS.

423. This is so nearly the same that an account of the internal structure
of stems may serve for the root also.

424. At the beginning, either in the embryo or in an incipient shoot
from a bud, the whole stem is of tender cellular tissue or parenchyma.
But wood (consisting of wood-cells and ducts or vessels) begins to be
formed in the earliest growth ; and is from the first arranged in two ways,
making two general kinds of wood. The difference is obvious even in
herbs, but is more conspicuous in the enduring stems of shrubs and
trees.

425. On one or the other of these two types the stems of all phanero-
gamous plants are constructed. In one, the wood is made up of separate
threads, scattered here and there throughout the whole diameter of the
stem. In the other, the wood is all collected to form a layer (in a slice
across the stem appearing as a ring) between a central cellular part which
has none in it, the Pith, and an outer cellular part, the Bark.

An Asparagus-shoot and a Corn-stalk for herbs, and a rattan for a
woody kind, represent the first kind. To it
belong all plants with monocotyledonous em-
bryo (40). A Bean-stalk
and the stem of any com-
mon shrub or tree rep-
resent the second; and

to it belong all plants with dicotyledonous or polycotyledonous embryo.
The first has been called, not very properly, Endogenous, which means in-
side-growing ; the second, properly enough, Exogenous, or outside-growing.
427. Endogenous Stems, those of Monocotyls (40), attain their
greatest size and most characteristic development in Palms and Dragon-
trees, therefore chiefly in warm climates, although the Palmetto and some

Yuccas become trees along the southern borders of the United States. la
such stems the woody bundles are more numerous and crowded toward the
circumference, and so the harder wood is outside ; while in an exogenous
stem the oldest and hardest wood is toward the centre. An endogenous
stem has no clear distinction of pith, bark, and wood, concentrically ar-
ranged, no silver grain, no annual layers, no bark that peels off clean from
the wood. Yet old stems of Yuccas and the like, that continue to increase
in diameter, do form a sort of layers and a kind of scaly bark when old.
Yuccas show well the curving of the woody bundles (Fig. 471) which
below taper out and are lost at the rind.

428. Exogenous Stems, those of Dicotyls (37), or of plants coming
from dicotyledonous and also polycotyledonous embryos, have
a structure which is familiar in the wood of our ordinary
trees and shrubs. It is the same in an herbaceous shoot
(such as a Flax-stem, Fig. 474) as in a Maple-stem of the
first year's growth, except that the woody layer is com-
monly thinner or perhaps reduced to a circle of bundles.
It was so in the tree-stem at the beginning. The wood all
forms in a cylinder, — in cross section a ring — around a cen-
tral cellular part, dividing the cellular core within, the pith, from a cellu
lar bark without. As the wood-bundles increase in number and in size,

they press upon each other and become wedge-shaped in the cross sec-
tion ; and they continue to grow from the outside, next the bark, so that
they become very thin wedges or plates. Between the plates or wedges
are very thin plates (in cross section lines) of much compressed cellular
tissue, which connect the pith with the bark. The plan of a one-year-old
woody stem of this kind is exhibited in the figures, which are essentially
diagrams.
429. When such a stem grows on from year to year, it adds annually a

layer of wood outside the preceding one, between that and the bark. This
is exogenous growth, or outside-growing, as the name denotes.
430. Some new bark is formed every year, as well as new wood, the

former inside, as the latter
is outside of that of the
year preceding. The ring
or zone of tender forming
tissue between the bark
and the wood has been
called the Cambium Layer.
Cambium is an old name
of the physiologists for
nutritive juice. And this
thin layer is so gorged
with rich nutritive sap
when spring growth is re-
newed, that the bark then
seems to be loose from
the wood and a layer of
viscid sap (or cambium) to
be poured out between the
two. But there is all
the while a connection of
the bark and the wood by
delicate cells, rapidly mul-
tiplying and growing.

431. The Bark of a
year-old stem consists of
three parts, more or less distinct, namely, — beginning next the wood, —

1. THE LIBER or FIBROUS BARK, the Inner Bark. This contains some
wood-cells, or their equivalent, commonly in the form of bast or bast-cells
(411, Fig. 444), such as those of Basswood or Linden, and among herbs
those of flax and hemp, which are spun and woven or made into cordage.
It also contains cells which are named sieve-cells, on account of numerous
slits and pores in their walls, by which the protoplasm of contiguous cells
communicates. In woody stems, whenever a new layer ot wood is formed,
some new liber or inner bark is also formed 01 t^ide of it.

ANATOMY OF STEMS.

141

2. THE GREEN BARK or Middle Bark. This consists of cellular tissue
only, and contains the same green matter (chlorophyll, 417) as the leaves.
In woody stems, before the season's growth is completed, it becomes cov-
ered by

3. THE CORKY LAYER or Outer Bark, the cells of which contain no
chlorophyll, and are of the nature of cork. Common cork is the thick
corky layer of the bark of the Cork-Oak of Spain. It is this which gives
to the stems or twigs of shrubs and trees the aspect and the color peculiar
to each, — light gray in the Ash, purple in the Red Maple, red in several
Dogwoods, etc.

4. THE EPIDERMIS, or skin of the plant, consisting of a layer of thick-
sided empty cells, which may be considered to be the outermost layer, or
in most herbaceous stems the only layer, of cork-cells.

481

432. The green layer of bark seldom grows much after the first season.
Sometimes the corky layer grows and forms new layers, inside of the old,
for years, as in the Cork-Oak, the Sweet Gum-tree, and the White and the
Paper Birch. But it all dies after a while ; and the continual enlargement
of the wood within finally stretches it more than it can bear, and sooner or
later cracks and rends it, while the weather acts powerfully upon its sur-
face ; so the older bark perishes and falls away piecemeal year by year.

433. So on old trunks only the inner bark remains. This is renewed
every year from within and so kept alive, while the older and outer layers
die, are fissured and rent by the distending trunk, weathered and worn, and
thrown off in fragments, — in some trees slowly, so that the bark of old
trunks may acquire great thickness ; in others, more rapidly. In Honey-
suckles and Grape-Vines, the layers of liber loosen and die when only a
year or two old. The annual layers of liber are sometimes as distinct as
those of the wood, but often not so.

142 VEGETABLE LIFE AND WORK. [SECTION 16.

4-34. The Wood of an exogenous trunk, having the old growths covered
by the new, remains nearly unchanged in age, except from decay. Wherever
there is an annual suspension and renewal of growth, as in temperate cli-
mates, the annual growths are more or less distinctly marked, in the form
of concentric rings on the cross section, so that the age of the tree may be
known by counting them. Over twelve hundred layers have been counted
on the ptumps of Sequoias in California, and it is probable that some trees
now living antedate the Christian era.

435. The reason why the annual growths are distinguishable is, that the
wood formed at the beginning of the season is more or less different in the
size or character of the cells from that of the close. In Oak, Chestnut, etc.,
the first wood of the season abounds in dotted ducts, the calibre of which
is many times greater than that of the proper wood-cells.

436. Sap-wood, or Alburnum. This is the newer wood, living or
recently alive, and taking part in the conveyance of sap. Sooner or later,
each layer, as it becomes more and more deeply covered by the newer ones
aud farther from the region of growth, is converted into

437. Heart-wood, or Duramen. This is drier, harder, more solid,
and much more durable as timber, than sap-wood. It is generally of a
different color, and it exhibits in different species the hue peculiar to each,
such as reddish in Red-Cedar, brown in Black- Walnut, black in Ebony, etc.
The change of sap-wood into heart-wood results from the thickening of the
walls of the wood-cells by the deposition of hard matter, lining the tubes
and diminishing their calibre; and by the deposition of a vegetable coloring-
matter peculiar to each species. The heart- wood, being no longer a living
part, may decay, and often does so, without the least injury to the tree,
except by diminishing the strength of the trunk, and so rendering it more
liable to be overthrown.

438. The Living Parts of a Tree, of the exogenous kind, are only
these : first, the rootlets at one extremity ; second, the buds and leaves of
the season at the other ; and third, a zone consisting of the newest wood
and the newest bark, connecting the rootlets with the buds or leaves, how-
ever widely separated these may be, — in the tallest trees from two to foui
hundred feet apart. And these parts of the tree are all renewed every year.
No wonder, therefore, that trees may live so long, since they annually re-
produce everything that is essential to their life and growth, and since only
a very small part of their bulk is alive at once. The tree survives, but
nothing now living has been so long. In it, as elsewhere, life is a transi-
tory thing, ever abandoning the old, and renewed in the young.

| 4. ANATOMY OF LEAYEa

439. The wood in leaves is the framework of ribs, veins, and rcinlets

(125), serving not only to strengthen them, but also to bring in the sap,
distribute it throughout rrery part. The cellular portion is the

143

green pulp, and is nearly the same as the green layer of the bark. So that
the leaf may properly enough be regarded as a sort of expansion of the
fibrous and green layers of the bark. It has no proper corky layer ; but
the whole is covered by a transparent skin or epidermis, resembling that
of the stem.

440. The cells of the leaf are of various forms, rarely so compact as to
form a close cellular tissue, usually loosely arranged, at least in the lower
part, so as to give copious intervening spaces or air passages, communi-
cating throughout the whole interior (Fig. 443, 483). The green color is
given by the chlorophyll (417), seen through the very transparent walls of
the cells and through the translucent epidermis of the leaf.

441. In ordinary leaves, having an upper and under surface, the green
cells form two distinct strata, of different arrangement. Those of the
upper stratum are oblong or cylindrical, and stand endwise to the surface
of the leaf, usually close together, leaving hardly any vacant spaces ; those
of the lower are commonly irregular in shape, most of them with their
longer diameter parallel to the face of the leaf, and are very loosely ar-
ranged, leaving many and wide air-chambers. The green color of the
lower is therefore diluted, and paler than that of the upper face of the leaf.
The upper part of the leaf is so constructed as to bear the direct action

of the sunshine ; the lower so as to afford freer circulation of air, and to
facilitate transpiration. It communicates more directly than the upper
with the external air by means of Stomates.

442. The Epidermis or skin of leaves and all young shoots is best
seen in the foliage. It may readily be stripped off from the surface of a
Lily-leaf, and still more so from more fleshy and soft leaves, such as those

Fia. 483. Magnified section of a leaf of White Lily, to exhibit the cellular

of Houseleek. The epidermis is usually composed of a single layer, occa
sionally of two or three layers, of empty
cells, mostly of irregular outline. The sin-
uous lines which traverse it, and may be dis-

cerned under low powers of the microscope (Fig. 487), are the boundaries
of the epidermal cells.

443. Breathing-pores, or Stomates, Stomata (singular, a Stoma, —
literally, a mouth) are openings through the epidermis into the air-chambers
or intercellular passages, always between and guarded by a pair of thin-
walled guardian cells. Although most abundant in leaves, especially on
their lower face (that which is screened from direct sunlight), they are
found on most other green parts. They establish a direct communication
between the external air and that in the loose interior of the leaf. Their
guardian cells or lips, which are soft and delicate, like those of the green
pulp within, by their greater or less turgidity open or close the orifice as the
moisture or dryness varies.

444. In the White Lily the stomata are so remarkably large that they
may be seen by a simple microscope of moderate power, and may be dis-
cerned even by a good hand lens. There are about 60,000 of them to the
square inch of the epidermis of the lower face of this Lily-leaf, and only
about 3000 to the same space on the upper face. It is computed that an
average leaf of an Apple-tree has on its lower face about 100,000 of these
mouths.

$5. PLANT FOOD AND ASSIMILATION.

445. Only plants are capable of originating organizable matter, or the
materials which compose the structure of vegetables and animals. The es-
sential and peculiar work of plants is to take up portions of earth and air
(water belonging to both) upon which animals cannot live at all, and to
convert them into something organizable ; that is, into something that,
under life, may be built up into vegetable and animal structures. All the
food of animals is produced by plants. Animals live upon vegetables,

directly or at second hand, the carnivorous upon the herbivorous; and
vegetables live upon earth and air, immediately or at second hand.

446. The Food of plants, then, primarily, is earth and air. This is
evident enough from the way in which they live. Many plants will flourish
111 pure sand or powdered chalk, or on the bare face of a rock or wall,
watered merely with rain. And almost any plant may be made to grow
from the seed in moist sand, and increase its weight many times, even if it
will not come to perfection. Many naturally live suspended from the
branches of trees high in the air, and nourished by it alone, never hav-
ing any connection with the soil ; and some which naturally grow en the
ground, like the Live-forever of the gardens, when pulled up by the roots
and hung in the air will often flourish the whole summer long.

447. It is true that fast-growing plants, or those which produce much
vegetable matter in one season (especially in such concentrated form as
to be useful as food for man or the higher animals) will come to maturity
only in an enriched soil. But what is a rich soil ? One which contains
decomposing vegetable matter, or some decomposing animal matter ; that
is, in either case, some decomposing organic matter formerly produced b^
plants. Aided by this, grain-bearing and other important vegetables will
grow more rapidly and vigorously, and make a greater amount of nourish-
ing matter, than they could if left to do the whole work at once from the
beginning. So that in these cases also all the organic or organizable matter
was made by plants, and made out of earth and air. Far the larger and
most essential part was air and water.

448. Two kinds of material are taken in and used by plants ; of which
the first, although more or less essential to perfect plant-growth, are in a
certain sense subsidiary, if not accidental, viz. : —

• Earthy constituents, those which are left in the form of ashes when a leaf
or a stick of wood is burned in the open air. These consist of some potash
(or soda in a marine plant), some mlex (the same as flint), and a little lime,
alumine, or magnesia, iron or manganese, sulphur, phosphorus, etc., — some
or all of these in variable and usually minute proportions. They are such
materials as happen to be dissolved, in small quantity, in the water taken
up by the roots ; and when that is consumed by the plant, or flies off pure
(as it largely does) by exhalation, the earthy matter is left behind in the
cells, — just as it is left incrusting the sides of a. teakettle m which much
hard water has been boiled. Naturally, therefore, there is more earths
matter (i. e. more ashes) in the leaves than in any other part (sometimes
as much as seven per cent, when the wood contains only two per cent) ;
because it is through the leaves that most of the water escapes from the
plant. Some of this earthy matter incrusts the cell-walls, some goes to
form crystals or rhaphides, which abound in many plants (422), some
enters into certain special vegetable products, and some appears to be ne-
cessary to the well-being of the higher orders of plants, although forming
no necessary part of the proper vegetable structure.
10

146 VEGETABLE LIFE AND WORK. [SECTION 16,

The essential constituents of the organic fabric are those which are dissi-
pated into a;r and vapor in complete burning. They make up from 88 to
99 per cent of the leaf or stem, and essentially the whole both of the cellu-
lose of the walls and the protoplasm of the contents. Burning gives these
materials of the plant's structure back to the air, mainly in the same condi-
tion in which the plant took them, the same condition which is reached
more slowly in natural decay. The chemical elements of the cell-walls (or
cellulose, 402), as also of starch, sugar, and all that class of orgauizable
cell-material, are carbon, hydrogen, and oxygen (399). The same, with
nitrogen, are the constituents of protoplasm, or the truly vital part of
vegetation.

449. These chemical elements out of which organic matters are com-
posed are supplied to the plant by water, carbonic acid, and some combina-
tions of nitrogen.

Water, far more largely than anything else, is imbibed by the roots ; also
more or less by the foliage in the form of vapor. Water consists of oxygen
and hydrogen; and cellulose or plant- wall, starch, sugar, etc., however
different in their qualities, agree in containing these two elements in the
same relative proportions as in water.

Carbonic acid gas (Carbon dioxide) is one of the components of the atmos-
phere, — a small one, ordinarily only about a^00 of its bulk, — sufficient
for the supply of vegetation, but not enough to be injurious to animals, as it
would be if accumulated. Every current or breeze of air brings to the leaves
expanded in it a succession of fresh atoms of carbonic acid, which it absorbs
through its multitudinous breathing-pores. This gas is also taken up by
water. So it is brought to the ground by rain, and is absorbed by the roots
of plants, either as dissolved in the water they imbibe, or in the form of
gas in the interstices of the soil. Manured ground, that is, soil containing
decomposing vegetable or animal matters, is constantly giving out this gas
into the interstices of the soil, whence the roots of the growing crop absorb
it. Carbonic acid thus supplied, primarily from the air, is the source of the
carbon which forms much the largest part of the substance of every plant
The proportion of carbon may be roughly estimated by charring some wood
or foliage ; that is, by heating it out of contact with the air, so as to decom-
pose and drive off all the other constituents 0* the fabric, leaving the large
bulk of charcoal or carbon behind.

Nitrogen, the remaining plant-element, is a gas which makes up more
than two thirds of the atmosphere, is brought into the foliage and also to
the roots (being moderately soluble in water) in the same ways as is car-
bonic acid. The nitrogen which, mixed with oxygen, a little carbonic acid,
and vapor of water, constitutes the air we breathe, is the source of this
fourth plant-element. But it is very doubtful if ordinary plants can use
any nitrogen gas directly as food ; that is, if they can directly cause it to
combine with the other elements so as to form protoplasm. But when com-
bined with hydrogen 'forming ammonia), or when combined with oxygen

SECTION 16.] PLANT FOOD AND ASSIMILATION. 147

(nitric acid and nitrates) plants appropriate it with avidity. And several
natural processes are going on in which nitrogen of the air is so combined
and supplied to the soil in forms directly available to the plant. The most
efficient is nitrification, the formation of nitre (nitrate of potash) in the soil,
especially in all fertile soils, through the action of a bacterial ferment.

450. Assimilation in plants is the conversion of these inorganic sub-
stances — essentially, water, carbonic acid, and some form of combined or
combinable nitrogen — into vegetable matter. This most dilute food the
living plant concentrates and assimilates to itself. Only plants are capable
of converting these mineral into organizable matters ; and this all-important
work is done by them (so far as all ordinary vegetation is concerned) only

451. Under the light of the sun, acting upon green parts or foliage, that
is, upon the chlorophyll, or upon what answers to chlorophyll, which these
parts contain. The sun in some way supplies a power which enables the
living plant to originate these peculiar chemical combinations, — to organ-
ize matter into forms which are alone capable of being endowed with life.
The proof of this proposition is simple ; and it shows at the same time, in
the simplest way, what a plant does with the water and carbonic acid it
consumes. Namely, 1st, it is only in sunshine or bright daylight that the
green parts of plants give out oxygen gas, — then they regularly do so ;
and 2d, the giving out of this oxygen gas is required to render the chemical
composition of water and carbonic acid the same as that of cellulose, that
is, of the plant's permanent fabric. This shows why plants spread out so
large a surface of foliage. Leaves are so many workshops, full of ma-
chinery worked by sun-power. The emission of oxygen gas from any
sun-lit foliage is seen by placing some of this under water, or by using an
aquatic plant, by collecting the air bubbles which rise, and by noting that
a taper burns brighter in this air. Or a leafy plant in a glass globe may
be supplied with a certain small percentage of carbonic acid gas, and after
proper exposure to sunshine, the air on being tested will be found to con-
tain less carbonic acid and just so much the more oxygen gas.

452. Now if the plant is making cellulose or any equivalent substance,
— that is, is making the very materials of its fabric and growth, as must
generally be the case, — all this oxygen gas given off by the leaves comes
from the decomposition of carbonic acid taken in by the plant. For cellu-
lose, and also starch, dextrine, sugar, and the like are composed of carbon
along with oxygen and hydrogen in just the proportions to form water.
And the carbonic acid and water taken in, less the oxygen which the carbon
brought with it as carbonic acid, and which is given off from the foliage in
sunshine, just represents the manufactured article, cellulose.

453. It comes to the same if the first product of assimilation is sugar,
or dextrine which is a sort of soluble starch, or starch itself. And in the
plant all these forms are readily changed into -one another. In the tiny
seedling, as fast as this assimilated matter is formed it is used in growth,
that is, in the formation of cell-walls. After a time some or much 01

148 VEGETABLE LIFE AND WORK, [SECTION 16.

the product may be accumulated in store for future growth, as in the root
of the turuip, or the tuber of the potato, or the seed of corn or pulse.
This store is mainly in the form of starch. When growth begins anew,
this starch is turned into dextrine or into sugar, in liquid form, and used
to nourish and build up the germinating embryo or the new shoot, where
it is at length converted into cellulose and used to build up plant-structure.

454. But that which builds plant-fabric is not the cellular structure
itself; the work is done by the living protoplasm which dwells within the
walls. This also has to take and to assimilate its proper food, for its own
maintenance and growth. Protoplasm assimilates, along with the other
three elements, the nitrogen of the plant's food. This comes primarily from
the vast stock in the atmosphere, but mainly through the earth, where it is
accumulated through various processes in a fertile soil, — mainly, so far as
concerns crops, from the decomposition of former vegetables and animals.
This protoplasm, which is formed at the same time as the simpler cellulose,
is essentially the same as the flesh of animals, and the source of it. It is
the common basis of vegetable and of animal life.

455. So plant-assimilation produces all the food and fabric of animals.
Starch, sugar, the oils (which are, as it were, these farinaceous matters
more deoxidated), chlorophyll, and the like, and even cellulose itself, form
the food of herbivorous animals and much of the food of man. When
digested they enter into the blood, undergo various transformations, and are
at length decomposed into carbonic acid and water, and exhaled from the
lungs in respiration, — in other words, are given back to the air by the ani-
mal as the very same materials which the plant took from the air as its food,
— are given back to the air in the same form that they would have taken if
the vegetable matter had been left to decay where it grew, or if it had been
set on fire and burned ; and with the same result, too, as to the heat, — the
heat in this case producing and maintaining the proper temperature of the
animal.

456. The protoplasm and other products containing nitrogen (gluten,
legumine, etc.), and which are most accumulated in grains and seeds (for
the nourishment of their embryos when they germinate), compose the most
nutritious vegetable food consumed by animals; they form their proper
flesh and sinews, while the earthy constituents of the plant form the earthy
matter of the bones, etc. At length decomposed, in the secretions and
excretions, these nitrogenous constituents are through successive changes
finally resolved into mineral matter, into carbonic acid, water, and ammonia
or some nitrates, — into exactly or essentially the same materials which the
plants took up and assimilated. Animals depend upon vegetables abso-
lutely and directly for their subsistence ; also indirectly, because

457. Plants purify the air for animals. In the very process by which they
create food they take from the air carbonic acid gas, injurious to animal res-
piration, which is continually poured into it by the breathing of all animals,
by all decay, by the burning of fuel and all other ordinary combustion; and

SECTION 16.] MOVEMENTS. 149

they restore an equal bulk of life-sustaining oxygen needful for the respiration
of animals, — needful, also, in a certain measure, for plants in any work they
do. for in plants, as well as in animals, work is done at a certain cost

$ 6. PLANT WORK AND MOVEMENT.

458. As the organic basis and truly living material of plants is identical
with that of animals, so is the life at bottom essentially the same ; but in
animals iomething is added at every rise from the lowest to highest organ-
isms. Action and work in living beings require movement.

459. Living things move; those not living are only moved. Plants
move as truly as do animals. The latter, nourished as they are upon or-
ganized food, which has been prepared for them by plants, and is found
only here and there, must needs have the power of going after it, of collect-
ing it, or at least of taking it in ; which requires them to make spontaneous
movements. But ordinary plants, with their wide-spread surface, always
in contact with the earth and air on which they feed, — the latter every-
where the same, and the former very much so, — might be thought to have
no need of movement. Ordinary plants, indeed, have no locomotion ; some
float, but most are rooted to the spot where they grew. Yet probably all
of them execute various movements which must be as truly self-caused as
are those of the lower grades of animals, — movements which are over-
looked only because too slow to be directly observed. Nevertheless, the
motion of the hour-hand and of the minute-hand of a watch is not less real
than that of the second-hand.

460. Locomotion. Moreover, many microscopic plants living in water
are seen to move freely, if not briskly, under the microscope ; and so like-
wise do more conspicuous

aquatic plants in their embryo-
like or seedling state. Even at
maturity, species of Oscillaria
(such as in Fig. 488, minute
worm-shaped plants of fresh
waters, taking this name from
their oscillating motions) freely «88

execute three different kinds

of movement, the very delicate investing coat of cellulose not impeding the
action of the living protoplasm within. Even when this coat is firmer and
hardened with a siliceous deposit, such crescent-shaped or boat-shaped
one-celled plants as Closterium or Navicula are able in some way to move
along from place to place in the water.

461. Movements in Cells, or Cell-circulation, sometimes called Cy-
closis, has been detected in so many plants, especially in comparatively

Fia. 488. Two individuals of an Oscillaria, magnified.

transparent aquatic plants and in hairs on the surface of land plants (where
it is easiest to observe), that it may be inferred to take place in all cells
during the most active part of their life. This motion is commonly a
streaming movement of threads of protoplasm, carrying
along solid granules by which the action may be ob-
served and the rate measured, or in some cases it is a
rotation of the whole protoplasmic contents of the cell.
A comparatively low magnifying power will show it in
the cells of Nitella and Chara (which are cryptogamous
plants) ; and under a moderate power it is well seen in
the Tape Grass of fresh water, Vallisneria, and in Naias
flexilis (Fig. 489). Minute particles and larger green-
ish globules are seen to be carried along, as if in a cur-
rent, around the cell, passing up one side, across the
end, down the other and across the bottom, completing
the circuit sometimes within a minute or less when well
warmed. To see it well in the cell, which like a string
of beads form the hairs on the stamens of Spiderwort,
a high magnifying power is needed.

462. Transference of Liquid from Cell to Cell,
and so from place to place in the plant, the absorption
of water by the rootlets, and the exhalation of the
greater part of it from the foliage, — these and similar
operations are governed by the physical laws which
regulate the diffusion of fluids, but are controlled by the
action of living protoplasm. Equally under vital control
are the various chemical transformations which attend
assimilation and growth, and which involve not only molecular movements
but conveyance. Growth itself, which is the formation and shaping of
new parts, implies the direction of internal activities to definite ends.

463. Movements of Organs. The living protoplasm, in all but the
lowest grade of plants, is enclosed and to common appearance isolated in
separate cells, the walls of which can only in their earliest state be said to
be alive. Still plants are able to cause the protoplasm of adjacent cells
to act in concert, and by their combined action to effect movements in
roots, stems, or leaves, some of them very slow and gradual, some manifest
and striking. Such movements are brought about through individually
minute changes in the form or tension in the protoplasm of the innumera-
ble cells which make up the structure of the organ. Some of the slower
movements are effected during growth, and may be explained by inequality
of growth on the two sides of the bending organ. But the more rapid
changes of position, and some of the slow ones, cannot be so explained.

464. Root-movements. In its growth a root turns or bends away
from the light and toward the centre of the earth, so that in lengthening
it buries itself in the soil where it is to live and act. Every one must
have observed this in the germination of seeds. Careful observations have
shown that the tip of a growing root also makes little sweeps or short
movements from side to side. By this means it more readily insinuates
itself into yielding portions of the soil. The root-tips will also turn
toward moisture, and so secure the most favorable positions in the soil.

465. Stem-movements. The root end of the caulicle or first joint of
stem (that below the cotyledons) acts like the root, in turning downward
in germination (making a complete bend to do so if it happens to point
upward as the seed lies in the ground), while the other end turns or
points skyward. These opposite positions are taken in complete dark-
ness as readily as in the light, in dryness as much as in moisture : there
fore, so far as these movements are physical, the two portions of the same
internode appear to be oppositely affected by gravitation or other in-
fluences.

466. Rising into the air, the stem and green shoots generally', while
young and pliable, bend or direct themselves toward the light, or toward
the stronger light when unequally illuminated; while roots turn toward the
darkness.

467. Many growing stems have also a movement of Nutation, that is,
of nodding successively in different directions. This is brought about by
a temporary increase of turgidity of the cells along one side, thus bowing
the stem over to the opposite side ; and this line of turgescence travels
round the shoot continually, from right to left or from left to right accord-
ing to the species : thus the shoot bends to all points of the compass in
succession. Commonly this nutation is slight or hardly observable. It is
most marked in

468. Twining Stems (Fig. 90). The growing upper end of such
stems, as is familiar in the Hop, Pole Beans, and Morning-Glory, turns
over in an inclined or horizontal direction, thus stretching out to reach a
neighboring support, and by the continual change in the direction of the
nodding, sweeps the whole circle, the sweeps being the longer as the stem
lengthens. When it strikes against a support, such as a stem or branch of
a neighboring plant, the motion is arrested at the contact, but continues
at the growing apex beyond, and this apex is thus made to wind spirally
around the supporting body.

469. Leaf-movements are all but universal. The presentation by
most leaves of their upper surface to the light, from whatever direction
that may come, is an instance ; for when turned upside down they twist or
bend round on the stalk to recover this normal position. Leaves, and the
leaflets of compound leaves, change this position at nightfall, or when the
light is withdrawn ; they then take what is called their sleeping posture,
resuming the diurnal position when daylight returns. This is very striking

152 VEGETABLE LIFE AND WORK. [SECTION 16.

in Locust-trees, in the Sensitive Plant (Fig. 490), and in Woodsorrel.
Yonng seedlings droop or close their leaves at night iu plants which are
not thus affected in the adult foliage. All this is thought to be a protec-
tion against the cold by nocturnal radiation.

470. Various plants climb by a coiling movement of their leaves or their
leaf-stalks. Familiar examples are seen in Clematis, Maurandia, Tropseo-
lum, and in a Solanum which is much cultivated in greenhouses (Fig. 172).
In the latter, and in other woody plants which climb in this way, the
petioles thicken and harden after they have grasped their support, thus
securing a very firm hold.

471. Tendril movements. Tendrils are either leaves or stems (98,
168), specially developed for climbing purposes. Cobsea is a good exam.
pie of partial transformation ; some of the leaflets are normal, some of the
same leaf are little tendrils, and some intermediate in character. The
Passion-flowers give good examples of simple stem-tendrils (Fig. 92) ;
Grape-Vines, of branched ones. Most tendrils make revolving sweeps, like
those of twining stems. Those of some Passion-flowers, in sultry weather,
are apt to move fast enough for the movement actually to be seen for a part
of the circuit, as plainly as that of the second-hand of a watch. Two
herbaceous species, Passiflora gracilis and P. sicyoides (the first an annual,
the second a strong-rooted perennial of the easiest

cultivation), are admirable for illustration both of
revolving movements and of sensitive coiling.

472. Movements under Irritation. The most
familiar case is that of the Sensitive Plant (Fig. 490).
The leaves suddenly take their nocturnal position
when roughly touched or when shocked by a jar.
The leaflets close in pairs, the four outspread par-
tial petioles come closer together, and the common
petiole is depressed.

The seat of the move-
ments is at the base of
the leaf-stalk and stalk-
lets. Schrankia, a near
relative of the Sensitive
Plant, acts in the same
way, but is slower.
These are not anoma-
lous actions, but only
extreme manifestations of a faculty more or less common in foliage. In
Locust and Honey-Locusts for example, repeated jars will slowly pro
duce similar effects.

473. Leaf-stalks and tendrils are adapted to their uses in climbing by a
similar sensitiveness. The coiling of the leaf-stalk is in response to a
kind of irritation produced by contact with the supporting body. This
may be shown by gentle rubbing or prolonged pressure upon the upper
face of toe leaf-stalk, which is soon followed by a curvature. Ten-
drils are still more sensitive to contact or light friction. This causes the
free end of the tendril to coil round the support, and the sensitiveness,
propagated downward along the tendril, causes that side of it to become
less turgescent or the opposite side more so, thus throwing the tendril into
coils. This shortening draws the plant up to the support. Tendrils which
have not laid hold will at length commonly coil spontaneously, in a simple
coil, from the free apex downward.

In Sicyos, Echinocystis, and the
above mentioned Passion-flowers
(471), the tendril is so sensitive,
under a high summer temperature,
that it will curve and coil prompt-
ly after one or two light strokes
by the hand.

474. Among spontaneous move-
ments the most singular are those
of Desmodium gyrans of India,
sometimes called Telegraph-plant,
which is cultivated on account of
this action. Of its three leaflets,
the larger (terminal) one moves
only by drooping at nightfall and
rising with the dawn. But its two
small lateral leaflets, when in a
congenial high temperature, by day
and by night move upward and
downward in a succession of jerks,
stopping occasionally, as if to re-
cover from exhaustion. In most
plant-movements some obviously
useful purpose is subserved : this
of Desmodium gyrans is a riddle.

475. Movements in Flowers are very various. The most remarkable
are in some way connected with fertilization (Sect. XIII.). Some occur
under irritation : the stamens of Barberry start forward when touched at
the base inside : those of many polyandrous flowers (of Sparmannia very
strikingly) spread outwardly when lightly brushed : the two lips or lobes

FIG. 491. Portion of stem and leaves of Telegraph-plant (Desmodium gyrans^

of the stigma in Mimulus close after a touch. Some are automatic and
are connected with dichogamy (339) : the style of Sabbatia and of large-
flowered species of Epilobium bends over strongly to one side or turns down-
ward when the blossom opens, but slowly erects itself a day or two later.

476. Extraordinary Movements connected with Capture of In-
sects. The most striking cases are those of Drosera and Dionaa; for an
account of which see "How Plants Behave," and Goodale's " Physiological
Botany."

477. The upper face of the leaves of the common species of Drosera,
or Sundew, is beset with stout bristles, having a glandular tip. This tip
secretes a drop of a clear but very viscid liquid, which glistens like a dew-
drop in the sun ; whence the popular name. When a fly or other small
insect, attracted by the liquid, alights upon the leaf, the viscid drops are so
tenacious that they hold it fast. In struggling it only becomes more com-
pletely entangled. Now the neighboring bris-
tles, which have not been touched, slowly bend
inward from all sides toward the captured in-
sect, and bring their sticky apex against its
body, thus increasing the number of bonds.
Moreover, the blade of the leaf commonly aids
in the capture by becoming concave, its sides
or edges turning inward, which brings still
more of the gland-tipped bristles into contact
with the captive's body. The insect per-
ishes ; the clear liquid disappears, apparently

by absorption into the tissue of
the leaf. It is thought that the
absorbed secretion takes with it
some of the juices of the insect
or the products of its decompo-
j sition.

478. Dionsea muscipula, the
most remarkable vegetable fly-trap
(Eig. 176, 492), is related to the
Sundews, and has a more special
and active apparatus for fly-
catching, formed of the summit
of the leaf. The two halves of this rounded body move as if they were
hinged upon the midrib; their edges are fringed with spiny but not
glandular bristles, which interlock when the organ closes. Upon the face
are two or three short and delicate bristles, which are sensitive. They do
not themselves move when touched, but they propagate the sensitiveness to
the organ itself, causing it to close with a quick movement. In a fresh

FIG, 492. Plant of Dionaea muscipula, or Venus's Fly-trap, reduced iu size.

SECTION 16.] TRANSFORMING MATERIAL AND ENERGY. 16$

and vigorous leaf, under a high summer temperature, and when the trap
lies widely open, a touch of any one of the minute bristles on the face, by
the finger or any extraneous body, springs the trap (so to say), and it
closes suddenly ; but after an hour or so it opens again. When a fly or
other small insect alights on the trap, it closes in the same manner, and so
quickly that the intercrossing marginal bristles obstruct the egress of the
insect, unless it be a small one and not worth taking. Afterwards and
more slowly it completely closes, and presses down upon the prey ; then
some hidden glands pour out a glairy liquid, which dissolves out the juices
of the insect's body ; next all is re-absorbed into the plant, and the trap
opens to repeat the operation. But the same leaf perhaps never captures
more than two or three insects. It ages instead, becomes more rigid and
motionless, or decays away.

479. That some few plants should thus take animal food will appear
less surprising when it is considered that hosts of plants of the lower grade,
known as Fungi, moulds, rusts, ferments, Bacteria, etc., live upon animal
or other organized matter, either decaying or living. That plants should
execute movements in order to accomplish the ends of their existence is
less surprising now when it is known that the living substance of plants
and animals is essentially the same ; that the beings of both kingdoms par-
take of a common life, to which, as they rise in the scale, other and higher
endowments are successively superadded.

480. Work uses up material and energy in plants as well as in ani-
mals. The latter live and work by the consumption and decomposition
of that which plants have assimilated into organizable matter through an
energy derived from the sun, and which is, so to say, stored up in the as-
similated products. In every internal action, as well as in every movement
and exertion, some portion of this assimilated matter is transformed and
of its stored energy expended. The steam-engine is an organism for con-
verting the sun's radiant energy, stored up by plants in the fuel, into me-
chanical work. An animal is an engine fed by vegetable fuel in the same
or other forms, from the same source, by the decomposition of which it
also does mechanical work. The plant is the producer of food and accumu-
lator of solar energy or force. But the plant, like the animal, is a con-
sumer whenever and by so much as it does any work except its great work
of assimilation. Every internal change and movement, every transforma-
tion, such as that of starch into sugar and of sugar into cell-walls, as well
as every movement of parts which becomes externally visible, is done at
the expense of a certain amount of its assimilated matter and of its stored
energy ; that is, by the decomposition or combustion of sugar or some such
product into carbonic acid and water, which is given back to the air, just
as in the animal it is given back to the air in respiration. So the respira-
tion of plants is as real and as essential as that of animals. But what plants
consume or decompose in their life and action is of insignificant amount in
comparison with what they compose.

i56 CRYPTOGAMOUS OR FLOWERLESS PLANTS. [SECTION 17.

SECTION XVII. CBYPTOGAMOUS OB FLOWEBLESS
PLANTS.

*81. Even the beginner in botany should have some general idea of
what cryptogamoua plants are, and what are the obvious distinctions of the
principal families. Although the lower grades are difficult, and need special
books and good microscopes for their study, the higher orders, such as
Ferns, may be determined almost as readily as phanerogamous plants.

482. Linna3us gave to this lower grade of plants the name of Crypto-
gamia, thereby indicating that their organs answering to stamens and
pistils, if they had any, were recondite and unknown. There is no valid
reason why this long-familiar name should not be kept up, along with the
counterpart one of Phanerogamic/, (6), although organs analogous to stamens
and pistil, or rather to pollen and ovule, have been discovered in all the
higher and most of the lower grades of this series of plants. So also
the English synonymous name of Flowerless Plants is both good and con-
venient : for they have not flowers in the proper sense. The essentials of
flowers are stamens and pistils, giving rise to seeds, and the essential of a
seed is an embryo (8). Cryptogamous or Flowerless plants are propagated
by SPORES; and a spore is not an embryo-plantlet, but mostly a single
plant-cell (399).

483. Vascular Cryptogams, which compose the higher orders of this
series of plants, have stems and (usually) leaves, constructed upon the
general plan of ordinary plants ; that is, they have wood (wood-cells and
vessels, 408) in the stem and leaves, in the latter as a frame work of veins.
But the lower grades, having only the more elementary cellular structure,
are called Cellular Cryptogams. Tar the larger number of the former are
Ferns : wherefore that class has been called

484. Pteridophyta, Pteridophytes in English form, meaning Fern-
plants,— that is, Ferns and their relatives. They are mainly Horsetails,
Ferns, Club-Mosses, and various aquatics which have been called Hydrop~
terides, i. e. Water-Ferns.

485. Horsetails, Equisetacea, is the name of a family which consists
only (among now-living plants) of Equisetum, the botanical name of Horse-
tail and Scouring Rush. They have hollow stems, with partitions at the
nodes ; the leaves consist only of a whorl of scales at each node, these
coalescent into a sheath : from the axils of these leaf-scales, in many species,
branches grow out, which are similar to the stem but on a much smaller
scale, close-jointed, and with the tips of the leaves more apparent. At the
apex of the stem appears the fructification, as it is called for lack of a better
term, in the form of a short spike or head. This consists of a good num-
ber of stalked shields, bearing on their inner or under face several wedge.
shaped spore-cases. The spore-cases when they ripen open down the innef

to he well seen by a hand-glass. The spores are aided in their discharge

and dissemination by four club-shaped threads attached to one part of them
These are hygrometric : when moist they are rolled
ap over the spore ; when dry they straighten,
and exhibit lively movements, closing over the
spore when breathed upon, and unrolling promptly
a moment after as they dry. (See Fig. 493-498.)
486. Ferns, or Filices, a most attractive family
of plants, are very numerous and varied. In warm
and equable climates some rise into forest-trees,
with habit of Palms ; but most of them are peren-
nial herbs. The wood of a Fern-trunk is very dif-
ferent, however, from that of a palm, or of any exogenous stem either. A
section is represented in Fig. 500. The curved plates of wood each ter-

always called a Fern-leaf a FROND, and its petiole a STIPE. Usage con-

surface of the leaf or frond, or over the whole surface when there are no
proper leaf-blades to the frond, but all is reduced to stalks. Commonly the
spore-cases occupy only detached spots or iines, each of which is called a
SOB,US} or in English merely a Fruit-dot. In many Ferns these fruit-dots
are naked ; in others they are produced under a scale-like bit of membrane,
called an INDUSIUM. In Maidenhair-Perns a little lobe of the leaf is folded
back over each fruit-dot, to serve as its shield or indusium. In the true
Brake or Bracken (Pteris) the whole edge of the fruit-bearing part of the
leaf is folded back over it like a hem.

488. The form and structure of the spore-cases can be made out with
a common hand magnifying glass. The commonest kind (shown in Fig.
503) has a stalk formed of a row of jointed cells, and is itself composed
of a layer of thin-walled cells, but is incompletely surrounded by a border of
thicker-walled cells, forming the RING. This extends from the stalk up
one side of the spore-case, round its summit, descends on the other side,
but there gradually vanishes. In ripening and drying the shrinking of the
cells of the ring on the outer side causes it to straighten ; in doing so it
tears the spore-case open on the weaker side and
discharges the minute spores that fill it, com-
monly with a jerk which scatters them to the
wind. Another kind of spore-case (Fig. 507)

is stalkless, and has its

ring-cells forming a kind

of cap at the top : at ma-
turity it splits from top

to bottom by a regular

dehiscence. A third kind

is of firm texture and.

opens across into two -

valves, like a clam-shell

(Fig. 508°) : this kind

makes an approach to the

next family.

489. The spores germi-
nate on moistened ground.

In a conservatory they

may be found germinating
on a damp wall or on the edges of a well- watered flower-pot. Instead oi
directly forming a fern-plantlet, the spore grows first into a body which

closely resembles a small Liverwort. This is named a PROTHALLTJS (Tig.
509) : from some point of this a bud appears to originate, which produce*
the first fern-leaf, soon followed by a second and third, and so the stem
and leaves of the plant are set up.

490. Investigation of this prothallus under the microscope resulted ii
the discovary of a wholly unsuspected kind of fertilization, taking place at

this germinating stage of the plant. On the under side of the prothallus
two kinds of organs appear (Fig. 510). One may be likened to an open
and depressed ovule, with a single cell at bottom answering to nucleus ;
the other, to an anther; but instead of pollen, it discharges corkscrew-
shaped microscopic filaments, which bear some cilia of extreme tenuity, by
the rapid vibration of which the filaments move freely over a wet surface.
These filaments travel over the surface of the prothallus, and even to other
prothalli (for there are natural hybrid Ferns), reach and enter the ovule

like cavities, and fertilize the cell. This thereupon sets up a growth, forms
a vegetable bud, and so develops the new plant.

491. An essentially similar process of fertilization has been discovered
in the preceding and the following families of Pteridophytes ; but it is
mostly subterranean and very difficult to observe.

492. Club-Mosses or Lycopodiums. Some of the common kinds,
called Ground Pine, are familiar, being largely used for Christmas wreaths
and other decoration. They are low evergreens, some creeping, all with
considerable wood in their stems : this thickly beset with small leaves. In
the axils of soice of these leaves, or more commonly, in the axils of pecu-
liar leaves changed into bracts (as in Fig. 511, 512) spore-cases appear, as
roundish or kidney-shaped bodies, of firm texture, opening round the top
into two valves, and discharging a great quantity of a very fine yellow
powder, the spores.

493. The Selaginellas have been separated from Lycopodium, which
they much resemble, because they produce two kinds of spores, in sepa-
rate spore-cases. One kind (MicnospOREs) is just that of Lycopodium ;
the other consists of only

four large spores (MACRO-
SPORES), in a spore-case
which usually breaks in
pieces at maturity (Fig.
513-515).

494. The Quillworts,
Isoetes (Fig. 516-519),
are very unlike Club Mos-
ses in aspect, but have been
associated with them. They
look more like Rushes, and
live in water, or partly out
of it. A very short stem,
like a corm, bears a cluster
of roots underneath ; above
it is covered by the broad
bases of a cluster of awl-
shaped or thread-shaped
leaves. The spore-cases
are immersed in the bases
of the leaves. The outer

leaf-bases contain numerous raacrospores ; the inner are filled with innu-
merable TLicrospores.

495. The Pillworts (Marsilia and Pilularia) are low aquatics, which

PIG. 520. Plant of Marsilia quadrifoliata, reduced in size \ at the right a pair of

162 CRYPTOGAMOUS OR FLOWERLESS PLANTS. [SECTION IT.

besx globular or pill-shaped fruit (SPOROCABPS) on the lower part of then
leaf-stalks or on their slender creeping stems. The leaves of the commoner
species of Marsilia might be taken for four-leaved Clover. (See Fig. 520.)
The sporocarps are usually raised on a short stalk. Within they are
divided lengthwise by a partition, and then crosswise by several partitions.
These partitions bear numerous deh'cate sacs or spore-cases of two kinds,
intermixed. The larger ones contain each a large spore, or macrospore ;
the smaller contain numerous microspores, immersed in mucilage. At
maturity the fruit bursts or splits open at top, and the two kinds of spores
are discharged. The large ones in germination produce a small prothallus ;
upon which the contents of the microspores act in the same way as in
Ferns, and with a similar result.

496. Azolla is a little floating plant, looking like a small Liverwort or
Moss. Its branches are covered with minute and scale-shaped leaves.
On the under side of the branches are found egg-shaped thin- walled sporo-
carps of two kinds. The small ones open across and discharge micro-
spores ; the larger burst irregularly, and bring to view globose spore-cases,
attached to the bottom of the sporocarp by a slender stalk. These delicate
spore-cases burst and set free about four macrospores, which are ferti-
lized at germination, in the manner of the Pillworts and Quillworts.
(See Fig. 521-526.)

497. Cellular Cryptogams (483) are so called because composed,
even in their higher forms, of cellular tissue only, without proper wood-
cells or vessels. Many of the lower kinds are mere plates, or ribbons,
or simple rows of cells, or even single cells. But their highest orders
follow the plan of Ferns and phanerogamous plants in having stem and
leaves for their upward growth, and commonly roots, or at least rootlets,

to attach them to the soil, or to trunks, or to other bodies on which they
grow. Plants of this grade are chiefly Mosses. So as a whole they take
the name of

498. Bryophyta, Bryophytes in English form, Bryum being the
Greek name of a Moss. These plants are of two principal kinds : true
Mosses (Musci) which is their Latin name in the plural) ; and Hepatic
Mosses, or Liverworts (Hepaticce).

499. Mosses or Musci. The pale Peat-mosses (species of Sphagnum,
the principal component of sphagnous bogs) and the strong-growing Hair-
cap Moss (Polytrichum) are among the lar-
ger and commoner representatives of this

numerous family; while Fountain MossfFon-
tinalis) in running water sometimes attains the
length of a yard or more. On the other hand,
some are barely individually distinguishable
to the naked eye. Fig. 52J' represents a com-
mon little Moss, enlarged to about twelve
times its natural size ; and by its side is part
of a leaf, much magnified, showing that it is
composed of cellular tissue (parenchyma-cells)
only. The leaves of Mosses are always sim-
ple, distinct, and sessile on the stem. The
fructification is an urn-shaped spore-case, in
this as in most cases raised on a slender stalk.
The spore-case loosely bears on its summit
a thin and pointed cap, like a candle-extin-
guisher, called a Calyptra. Detaching this, it
is found that the spore-case is like a pyxis
(376), that is, the top at maturity comes off
as a lid (Operculum} ; and that the interior is
filled with a green powder, the spores, which
are discharged through the open mouth. In
most Mosses there is a fringe of one or two
rows of teeth or membrane around this mouth e28 B27

or orifice, the Peristone. When moist the peristome closes hygrometri-
cally over the orifice more or less; when drier the teeth or processes
commonly bend outward or recurve ; and then the spores more readily es-
cape. In Hair-cap Moss a membrane is stretched quite across the mouth,
like a drum-head, retaining the spores until this wears away. See Figures
527-541 for details.

500. Fertilization in Mosses is by the analogues of stamens and pistils,
wrhich are hidden in the axils of leaves, or in the cluster of leaves at the

end of the stem. The analogue of the anther (Antheridium) is a cellulai
sac, which in bursting discharges innumerable delicate cells floating in a
mucilaginous liquid; each of these bursts and sets free a vibratile self-

moving thread. These threads, one or more, reach the orifice of the pistil-
shaped body, the Pistillidium, and act upon a particular cell at its base
within. Tliis cell in its growth develops into the spore-case and its stalk
(when there is any), carrying on its summit the wall of the pistillidium,
which becomes the calyptra.

501. Liverworts or Hepatio Mosses (Hepatic*) in some kinds re.
semble true Mosses, having distinct stem and leaves, although their leaves
occasionally run together ; while in others there is no distinction of stem
and leaf, but the whole plant is a leaf-like body, which produces rootlets on
the lower face and its fructification on the upper. Those of the moss-like
kind (sometimes called Scale-Mosses) have their tender spore-cases splitting
into four valves ; and with their spores are intermixed some slender spiral

and very hygrometric threads (called Slaters) which are thought to aid in
the dispersion of the spores. (Fig. 542-544.)

502. Marchantia, the commonest and largest of the true Liverworts,
forms large green plates or fronds on damp and shady ground, and sends up
from some part of the upper face a stout stalk, ending in a several-lobed
umbrella-shaped body, under the lobes of which hang several thin-walled
spore-cases, which burst open and discharge spores and elaters. Riccia
natans (Fig. 545) consists of wedge-shaped or heart-shaped fronds, which
float free in pools of still water. The under face bears copious rootlets ; in
the substance of the upper face are the spore-cases, their pointed tips

544

merely projecting: there they burst open, and discharge their spores,
These are comparatively few and large, and are in fours ; so they are very
like the macrospores of Pillworts or Quillworts.

503. Thallophyta, or Thallophytes in English form. This is the name
for the lower class of Cellular Cryptogams, — plants in which there is no
marked distinction into root, stem, and leaves. Roots in any proper sense
they never have, as organs for absorbing, although some of the larger
Seaweeds (such as the Sea Colander, Fig. 553) have them as holdfasts.
Instead of axis and foliage, there is a stratum of frond, in such plants
commonly called a THALLUS (by a strained use of a Greek and Latin word
which means a green shoot or bough), which may -have any kind of form,
leaf-like, stem-like, branchy, extended to a flat plate, or gathered into a
sphere, or drawn out into threads, or reduced to a single row of cells, or
even reduced to single cells. Indeed, Thallophytes are so multifarious, so
numerous in kinds, so protean in their stages and transformations, so re-
condite in their fructification, and many so microscopic in size, either of

the plant itself or its essential organs, that they have to be elaborately
described in separate books and made subjects of special study.

504. Nevertheless, it may be well to try to give some general idea of
what Algae and Lichens and Fungi are. Linnaeus had them all under the
orders of Algae and Fungi. Afterwards the Lichens were separated; but
646 646 647

of late it has been made most probable that a Lichen consists of an Alga
and a Fungus conjoined. At least it must be so in some of the ambiguous
forms. Botanists are in the way of bringing out new classifications of the
Thallophytes, as they come to understand their structure and relations
better. Here, it need only be said that

505. Lichens live in the air, that is, on the ground, or on rocks, trunks,
walls, and the like, and grow when moistened by rains. They assimilate air,
water, and some earthy matter, just as do ordinary plants. Algae, or Sea.

Fungi, whatever medium they inhabit, live as animals do, upon organic mat-
ter, — upon wfyat other plants have assimilated, or upon the products of

fcheir decay. True as these general distinctions are, it is no less true that
these orders run together in their lowest forms ; and that Algse and Fungi
may be traced down into forms so low and simple that no clear line can be
drawn between them ; and even into forms of which it is uncertain whether
they should be called plants or animals. It is as well to say that they are
not high enough in rank to be distinctively either the one or the other. On
the other hand there is a peculiar group of plants, which in simplicity of
composition resemble the simpler Algse, while in fructification and in the
arrangements of their simple cells into stem and branches they seem to be
of a higher order, viz. : —

506. Oharaces9. These are aquatic herbs, of considerable size, abound-
ing in ponds. The simpler kinds (Nitella) have the stem formed of a
single row of tubular cells, and at the nodes, or junction of the cells, a
whorl of similar branches. Chara (Fig. 550-552) is the same, except that
the cells which make up the stem and the principal branches are strength-
ened by a coating of many smaller tubular cells, applied to the surface
of the main or central cell. The fructifr
cation consists of a globular sporocarp
of considerable size, which is spirally

enwrapped by tubular cells twisted aronnd it : by the side of this is a
smaller and globular antheridium. The latter breaks up into eight shield-

shaped pieces, with an internal stalk, and bearing long and ribbor. -shaped
filaments, which consist of a row of delicate cells, each of which dis-
charges a free-moving microscopic thread (the analogue of the pollen or
pollen-tube), nearly in the manner of Ferns and Mosses. One of these
threads reaches and fertilizes a cell at the apex of the nucleus or solid
body of the sporocarp. This subsequently germinates and forms a new
individual.

507. Algae or Seaweeds. The proper Seaweeds may be studied by
the aid of Professor Farlow's " Marine Algffi of New England ; " the

fresh-water species, by Prof. H. C. Woods's " Fresh- water Alg« of North
America/' a larger and less accessible volume. A few common forms are
here very briefly mentioned and illustrated, to give an idea of the family.
But they are of almost endless diversity.

508. The common Rockweed (Fucus vesiculosus, Fig. 554, abounding
between high and low water mark on the coast), the rarer Sea Colander
(Agarum Turneri, Fig. 553), and Laminaria, of which the larger forms
are called Devil's Aprons, are good representatives of the olive green or
brownish Seaweeds. They are attached either by a disk-like base or by
root-like holdfasts to the rocks or stones on which they grow.

509. The hollow and inflated places in the Fucus vesiculosus or Rock-
weed (Fig- 554) are air-bladders for buoyancy. The fructification forms
in the substance of the tips of the frond : the rough dots mark the places
where the conceptacles open. The spores and the fertilizing cells are in
different plants. Sections of the two kinds of conceptacles are given in Fig.
555 and 556. The contents of the conceptacles are discharged through

a small orifice which in each figure is at the margin of the page. The large
spores are formed eight together in a mother-cell. The minute motile
filaments of the antheridia fertilize the large spores after injection into the
water: and then the latter promptly acquire a cell- wall and germinate.

5 10. The Floridese or Rose-red series of marine Algae (which, however,
are sometimes green or brownish) are the most attractive to amateurs.
The delicate Porphyra or Laver is in some countries eaten as a delicacy, and
the cartilaginous Cliondrus crispus has
been largely used for jelly. Besides their
conceptacles, which contain true spores
(Fig. 560), they mostly have a fructifi-
cation in Tetmspores, that is, of spores
originating in fours (Fig. 559).

511. The Grass-green Algae sometimes form broad membranous fronds,
such as those of the common Ulva of the sea-shore, but most of them form

mere threads, either simple or branched. To this division belong almost

all the Fresh-water Algae, such as those which constitute the silky threads
or green slime of running streams or standing pools, and which were all
called Confervas before their immense diversity was known. Some are
formed of a single row of cells, developed each from the end of another.
Others branch, the top of one cell producing more than one new one
(Fig. 564). Others, of a kind which is very common
in fresh water, simple threads made of a line of cells,
have the chlorophyll and protoplasm of each cell ar-
ranged in spiral lines or bands.
They form spores in a peculiar
way, which gives to this family the
designation of conjugating Algae.

512. At a certain time two par-
allel threads approach each other
more closely ; contiguous parts of

a cell of each thread bulge or grow out, and unite when they meet ; the
cell-wall partitions between them are absorbed so as to open a free commu-
nication; the spiral band of green matter in both cells breaks up ; the whole
of that of one cell passes over into the other ; and of the united contents
a large green spore is formed. Soon the old cells decay, and the spore

the life of two individuals to make a single new one would be fatal to the
species if there were not a provision for multiplication by the prompt divi-
sion of the new-formed individual into two, and these again into two, and
so on in geometrical ratio. And the costly process would be meaningless
if there were not some real advantage in such a fresh start, that is, in
sexes.

composed of slender sacs (Asci), having thread-shaped cells intermixed ;
and each ascus contains tew or several spores, which are commonly double
or treble. Most Lichens are flat expansions of grayish hue ; some of them
foliaceous in texture, but never of bright green color; more are crusta-
ceous ; some are wholly pulverulent and nearly formless. But in several

cells lengthen and branch, growing by the absorption through their whole
surface of the decaying, or organizable, or living matter which they feed
upon. In a Mushroom (Agaricus), a knobby mass is at length formed,
which develops into a stout stalk (Stipe), bearing the cap (P ileus) : the
under side of the cap is covered by the Hymenium, in this genus consisting
of radiating plates, the gills or Lamellae; and these bear the powdery spores
in immense numbers. Under the microscope, the gills are found to be
studded with projecting cells, each of which, at the top, produces four
stalked spores. These form the powder which collects on a sheet of paper
upon which a mature Mushroom is allowed to rest for a day or two. (Fig.
581-586.)

SECTION 18.] CLASSIFICATION. 175

SECTION XVIII. CLASSIFICATION AND NOMENCLATURE.

519. Classification, in botany, is the consideration of plants in respect
to their kinds and relationships. Some system of Nomenclature, or nam-
ing, is necessary for fixing and expressing botanical knowledge so as to
make it available. The vast multiplicity of plants and the various degrees
of their relationship imperatively require order and system, not only as to
names for designating the kinds of plants, but also as to terms for defining
their differences. Nomenclature is concerned with the names of plants.
Terminology supplies names of organs or parts, and terms to designate
their differences.

§ 1. KINDS AND RELATIONSHIP.

520. Plants and animals have two great peculiarities : 1st, they form
themselves ; and 2d, they multiply themselves. They reproduce their kind
in a continued succession of

521. Individuals. Mineral things occur as masses, which are divisible
into smaller and still smaller ones without alteration of properties. But
organic things (vegetables and animals) exist as individual beings. Each
owes its existence to a parent, and produces similar individuals in its turn.
So each individual is a link of a chain; and to this chain the natural-
historian applies the name of

522. Species. All the descendants from the same stock therefore com-
pose one species. And it was from our observing that the several sorts of
plants or animals steadily reproduce themselves, or, in other words, keep
up a succession of similar individuals, that the idea of species originated.
There are few species, however, in which man has actually observed the
succession for many generations. It could seldom be proved that all the
White Pine trees or White Oaks of any forest came from the same stock.
But observation having familiarized us with the general fact that indi-
viduals proceeding from the same stock are essentially alike, we infer from
their close resemblance that these similar individuals belong to the same
species. That is, we infer it when the individuals are as much like each
other as those are which we know, or confidently suppose, to have sprung
from the same stock.

523. Identity in species is inferred from close similarity in all essential
respects, or whenever the differences, however considerable, are not known
or reasonably supposed to have been originated in the course of time under
changed conditions. No two individuals are exactly alike ; a tendency to
variation pervades all living things. "In cultivation, where variations are
looked after and cared for, very striking differences come to light ; and if
in wild nature they are less common or less conspicuous, it is partly be-
cause they are uncared for. When such variant forms are pretty well
marked they are called

176 CLASSIFICATION. [SECTION 18.

524«. Varieties. The White Oak, for example, presents two or three
varieties in the shape of the leaves, although they may be all alike upon
each particular tree. The question often arises, and it is often hard to
answer, whether the difference in a particular case is that of a variety, or
is specific. If the former, it may commonly be proved by finding such
intermediate degrees of difference in various individuals as to show that
no clear distinction can be drawn between them ; or else by observing the
variety to vary back again in some of its offspring. The sorts of Apples,
Pears, Potatoes, and the like, show that differences which are permanent
in the individual, and continue unchanged through a long series of gen-
erations when propagated by division (as by offsets, cuttings, grafts,
bulbs, tubers, etc.), are not likely to be reproduced by seed. Still they
sometimes are so, and perhaps always tend in that direction. For the
fundamental law in organic nature is that offspring shall be like parent.

RACES are such strongly marked varieties, capable of coming true to
seed. The different sorts of Wheat, Maize, Peas, Radishes, etc., are
familiar examples. By selecting those individuals of a species which have
developed or inherited any desirable peculiarity, keeping them from min-
gling with their less promising brethren, and selecting again the most
promising plants raised from their seeds, the cultivator may in a few
generations render almost any variety transmissible by seed, so long as it is
cared for and kept apart. In fact, this is the way the cultivated domesti-
cated races, so useful to man, have been fixed and preserved. Races, in
fact, can hardly, if at all, be said to exist independently of man. But
man does not really produce them. Such peculiarities — often surprising
enough — now and then originate, we know not how (the plant sports, as
the gardeners say) ; they are only preserved, propagated, and generally
further developed, by the cultivator's skilful care. If left alone, they are
likely to dwindle and perish, or else revert to the original form of the
species. Vegetable races are commonly annuals, which can be kept up
only by seed, or herbs of which a succession of generations can be had
every year or two, and so the education by selection be completed without
great lapse of time. But all fruit-trees could probably be fixed into races
in an equal number of generations.

BUD-VARIETIES are those which spring from buds instead of seed.
They are uncommon to any marked extent. They are sometimes called
Sports, but this name is equally applied to variations among seedlings.

CROSS-BREEDS, strictly so-called, are the variations which come from
cross-fertilizing one variety of a species with another.

HYBRIDS are the varieties, if they may be so called, which come from
the crossing of species (331). Only nearly related species can be hybridized;
and the resulting progeny is usually self-sterile, but not always. Hybrid
plants, however, may often be fertilized and made prolific by the pollen
of one or the other parent. This produces another kind of cross-breeds.

525, Species are the units in classification. Varieties, although of

SECTION 18.] KINDS AND RELATIONSHIP. 177

utmost importance in cultivation and of considerable consequence in the
flora of any country, are of less botanical significance. For they are apt
to be indefinite and to shade off one form into another. But species, the
botanist expects to be distinct. Indeed, the practical difference to the
botanist between species and varieties is the definite limitation of the one
and the indefiniteness of the other. The botanist's determination is partly
a matter of observation, partly of judgment.

526. In an enlarged view, varieties may be incipient species ; and nearly
related species probably came from a common stock in earlier times. For
there is every reason to believe that existing vegetation came from the
more or less changed vegetation of a preceding geological era. However
that may be, species are regarded as permanent and essentially unchanged
in their succession of individuals through the actual ages.

527. There are, at nearly the lowest computation, as many as one hun-
dred thousand species of phanerogamous plants, and the cryptogamous
species are thought to be still more numerous. They are all connected by
resemblances or relationships, near and remote, which show that they are
all parts of one system, realizations in nature, as we may affirm, of the con-
ception of One Mind. As we survey them, they do not form a single and
connected chain, stretchiug from the lowest to the highest organized
species, although there obviously are lower and higher grades. But the
species throughout group themselves, as it were, into clusters or constel-
lations, and these into still more comprehensive clusters, and so on, with
gaps between. It is this clustering which is the ground of the recognition
of kinds of species, that is, of groups of species of successive grades or
degree of generality ; such as that of similar species into Genera, of genera
into Families or Orders, of orders into Classes. In classification the se-
quence, proceeding from higher or more general to lower or special, is always
CLASS, ORDER, GENUS, SPECIES, VARIETY (if need be).

528. Genera (in the singular, Genus) are assemblages of closely related
species, in which the essential parts are all constructed on the same partic-
ular type or plan. White Oak, Red Oak, Scarlet Oak, Live Oak, etc.,
are so many species of the Oak genus (Latin, Quercus). The Chestnuts
compose another genus; the Beeches another. The Apple, Pear, and
Crab are species of one genus, the Quince represents another, the various
species of Hawthorn a third. In the animal kingdom the common cat, the
wild-cat, the panther, the tiger, the leopard, and the lion are species of the
cat kind or genus ; while the dog, the jackal, the different species of wolf,
and the foxes, compose another genus. Some genera are represented by
a vast number of species, others by few, very many by only one known
species. For the genus may be as perfectly represented in one species as
in several, although, if this were the case throughout, genera and species
would of course be identical. The Beech genus- and the Chestnut genus
would be just as distinct from the Oak genus even if but one Beech and
one Chestnut WPJ-A Vnpwp ; as indeed was once the case.

178 CLASSIFICATION. [SECTION 18.

529. Orders are groups of genera that resemble each other ; that is,
they are to genera what genera are to species. As familiar illustrations,
the Oak, Chestnut, and Beech genera, along with the Hazel genus and the
Hornbeams, all belong to one order. The Birches and the Alders make
another; the Poplars and Willows, another; the Walnuts (with the But-
ternut) and the Hickories, still another. The Apple genus, the Quince
and the Hawthorns, along with the Plums and Cherries and the Peach,
the Raspberry with the Blackberry, the Strawberry, the Rose, belong
to a large order, which takes its name from the Rose. Most botanists
use the names "Order" and "Family" synonymously; the latter more
popularly, as "the Rose Family," the former more technically, as
"Order Rosacece"

530. But when the two are distinguished, as is common in zoology,
Family is of lower grade than Order.

531. Classes are still more comprehensive assemblages, or great groups.
Thus, in modern botany, the Dicotyledonous plants compose one class,
the Monocotyledonous plants another (36-40).

532. These four grades, Class, Order, Genus, Species, are of universal
use. Variety comes in upon occasion. For, although a species may have
no recognized varieties, a genus implies at least one species belonging to
it ; every genus is of some order, and every order of some class.

533. But these grades by no means exhaust the resources of clas-
sification, nor suffice for the elucidation of all the distinctions which
botanists recognize. In the first place, a higher grade than that of class
is needful for the most comprehensive of divisions, that of all plants into
the two Series of Phanerogamous and Cryptogamous (6) ; and in natu-
ral history there are the two Kingdoms or Realms, the Vegetable and
the Animal.

534. Moreover, the stages of the scaffolding have been variously ex-
tended, as required, by the recognition of assemblages lower than class but
higher than order, viz. Subclass and Cohort ; or lower than order, a Sub-
order; or between this and genus, a Tribe ; or between this and tribe, a
Subtribe ; or between genus and species, a Subgenus ; and by some a
species has been divided into Subspecies, and a variety into Subvarieties.
Last of all are Individuals, Suffice it to remember that the following are
the principal grades in classification, with the proper sequence ; also that
only those here printed in small capitals are fundamental and universal
in botany:—-

SECTION 18.J NOMENCLATURE. 179

{ 2. NAMES, TERMS, AND CHARACTERS,

535. The name of a plant is the name of its genus followed by that of
the species. The name of the genus answers to the surname (or family
name) ; that of the species to the baptismal name of a person. Thus Quer-
cm is the name of the Oak genus ; Quercus alba, that of the White Oak,
Q. rubra, that of Red Oak, Q. nigra, that of the Black-Jack, etc. Botani-
cal names being Latin or Latinized, the adjective name of the species
comes after that of the genus.

536. Names of Genera are of one word, a substantive. The older
ones are mostly classical Latin, or Greek adopted into Latin; such as
Quercus for the Oak genus, Fagus for the Beech, Corylus, the Hazel, and
the like. But as more genera became known, botanists had new names to
make or borrow. Many are named from some appearance or property of
the flowers, leaves, or other parts of the plant. To take a few examples
from the early pages of the " Manual of the Botany of the Northern United
States," — the genus Hepatica comes from the shape of the leaf, resembling
that of the liver. Myosurus means mouse-tail. Delphinium is from del-
phin, a dolphin, and alludes to the shape of the flower, which was thought
to resemble the classical figures of the dolphin. Xanthorrhiza is from two
Greek words meaning yellow-root, the common name of the plant. Cimi-
cifuga is formed of two Latin words meaning to drive away bugs, i. e.
Bugbane, the Siberian species being used to keep away such vermin.
Sanguinaria, the Bloodroot, is named from the blood-like color of its juice.
Other genera are dedicated to distinguished botanists or promoters of
science, and bear their names: such are Magnolia, which commemorates
the early French botanist, Magnol ; and Jejfersonia, named after President
Jefferson, who sent the first exploring expedition over the Rocky Moun-
tains. Others bear the name of the discoverer of the plant ; as, Sarra-
cenia, dedicated to Dr. Sarrazin, of Quebec, who was one of the first to
send the common Pitcher-plant to the botanists of Europe ; and Claytonia,
first made known by the early Virginian botanist Clayton.

537. Names of Species, The name of a species is also a single word,
appended to that of the genus. It is commonly an adjective, and therefore
agrees with the generic name in case, gender, etc. Sometimes it relates to
the country the species inhabits ; as, Claytonia Virginica, first made known
from Virginia; Sanguinaria Canadensis, from Canada, etc. More com-
monly it denotes some obvious or characteristic trait of the species ; as,
for example, in Sarracenia, our northern species is named purpurea, from
the purple blossoms, while a more southern one is named flava, because
its petals are yellow ; the species of Jeffersonia is called diphylla, meaning
two-leaved, because its leaf is divided into two leaflets. Some species are
named after the discoverer, or in compliment to a botanist who has made
them known ; as, Magnolia Fraseri, named after the botanist Eraser, one

180 NOMENCLATURE. [SECTION 18.

of the first to find this species ; and Sarracenia Drummondii, for a Pitcher-
plant found by Mr. Drummond in Florida. Such personal specific names
are of course written with a capital initial letter. Occasionally some old
substantive name is used for the species ; as Magnolia Umbrella, the Um-
brella tree, and Ranunculus Flammula. These are also written with a
capital initial, and need not accord with the generic name in gender. Geo-
graphical specific names, such as Canadensis, Caroliniana, Americana, in
the later usage are by some written without a capital initial, but the older
usage is better, or at least more accordant with English orthography.

538. Varietal Names, when any are required, are made on the plan of
specific names, and follow these, with the prefix var. Ranunculus Flam-
mula, var. reptansy the creeping variety: R. abortivus, var. micranthus,
the small-flowered variety of the species.

539. In recording the name of a plant it is usual to append the name,
or an abbreviation of the name, of the botanist who first published it ; and
in a flora or other systematic work, this reference to the source of the
name is completed by a further citation of the name of the book, the
volume and page where it was first published. So " Ranunculus acris,
L.," means that this Buttercup was first so named and described by Lin-
neeus ; " R. multijidus, Pursh," that this species was so named and pub-
lished by Pursh. The suffix is no part of the name, but is an abbreviated
reference, to be added or omitted as convenience or definiteness may re-
quire. The authority for a generic name is similarly recorded. Thus,
" Ranunculus, L.," means that the genus was so named by Linnaeus ;
" Myosurus, Dill.," that the Mouse- tail was established as a genus under
this name by Dillenius ; Caulophyllum, Michx., that the Blue Cohosh was
published under this name by Michaux. The full reference in the last-
named instance would be, " in Flora Boreali-Americana, first volume, 205th
page," — in the customary abbreviation, "Michx. Fl. i. 205."

540. Names of Orders are given in the plural number, and are com.
monly formed by prolonging the name of a genus of the group taken as a
representative of it. For example, the order of which the Buttercup or
Crowfoot genus, Ranunculus, is the representative, takes from it the name
of Ranunculacea ; meaning Plantee Ranunculacea when written out in
full, that is, Ranunculaceous Plants. Some old descriptive names of
orders are kept up, such as Crucifem for the order to which Cress and
Mustard belong, from the cruciform appearance of their expanded corolla,
and Umbelliferee, from the flowers being in umbels.

541. Names of Tribes, also of suborders, sabtribes, and the like, are
plurals of the name of the typical genus, less prolonged, usually in eee,
*ne&, idea, etc. Thus the proper Buttercup tribe is Ranunculea, of the
Clematis tribe, Clematidea. While the Rose family is Rosaceee, the special
Rose tribe is Roseau.

542. Names of Classes, eto. For these see the following synopsis of
khe actual classification adopted, p. 183,

SECTION 18.] TERMINOLOGY. 181

543. So a plant is named in two words, the generic and the specific
names, to which may be added a third, that of the variety, upon occasion.
The generic name is peculiar : obviously it must not be used twice over in
botany. The specific name must not be used twice over in the same genus,
but is free for any other genus. A Quercns alba, or White Oak, is no
hindrance to Betwla alba, or White Birch ; and so of other names.

544. Characters and Descriptions. Plants are characterized by a
terse statement, in botanical terms, of their peculiarities or distinguishing
marks. The character ot the order should include nothing which is com-
mon to the whole class U belongs to ; that of the genus, nothing which is
common to the ordev ; that of the species nothing which is shared with
all other species ot' the genus; and so of other divisions. Descriptions
may enter into complete details of the whole structure.

545. Terminology, also called Glossology, is nomenclature applied to
organs or p*\rts, and their forms or modifications. Each organ or special
part has P substantive name of its own : shapes and other modifications of
an organ or part are designated by adjective terms, or, when the forms
are peculiar, substantive names are given to them. By the correct use
of such botanical terms, and by proper subordination of the characters
under the order, genus, species, etc., plants may be described and deter-
mined with much precision. The classical language of botany is Latin.
While modern languages have their own names and terms, these usually
lack the precision of the Latin or Latinized botanical terminology. For-
tunately, this Latinized terminology has been largely adopted and incor.
porated into the English technical language of botany, thus securiug pre-
cision. And these terms are largely the basis of specific names of plants.

546. A glossary or vocabulary of the principal botanical terms used in
phanerogamous and vascular cryptogamous botany is appended to this
rolume, to which the student may refer, as occasion arises.

§ 3. SYSTEM.

547. Two systems of classification used to be recognized in botany, — the
artificial and the natural ; but only the latter is now thought to deserve
the name of a system.

548. Artificial classifications have for object merely the ascertaining
of the name and place of a plant. They do not attempt to express relation-
ships, but serve as a kind of dictionary. They distribute the genera and
species according to some one peculiarity or set of peculiarities (just as a
dictionary distributes words according to their first letters), disregarding
all other considerations. At present an artificial classification in botany
is needed only as a key to the natural orders, — as an aid in referring an
unknown plant to its proper family ; and such keys are still very needful,
at least for the beginner. Formerly, when the orders themselves were
not clearjy made out, an artificial classification was required to lead the

182 SYSTEM. [SECTION 18.

student down to the genus. Two such classifications were long in vogue :
First, that of Tournefort, founded mainly on the leaves of the flower, the
calyx and corolla : this was the prevalent system throughout the first half
of the eighteenth century ; but it has long since gone by. It was suc-
ceeded by the well-known

549. Artificial System of Linnaeus, which was founded on the sta-
mens and pistils. It consists of twenty-four classes, and of a variable
number of orders ; the classes founded mainly on the number and dispo-
sition of the stamens ; the orders partly upon the number of styles or stig-
mas, partly upon other considerations. Useful and popular as this system
was down to a time within the memory of still surviving botanists, it is
now completely obsolete. But the tradition of it survives in the names of
its classes, Monandria, Diandria, Triandria, etc., which are familiar in
terminology in the adjective terms monandrous, diandrous, triandrous, etc.
(284) ; also of the orders, Monogynia, Digynia, Trigynia, etc., preserved in
the form of monogynous, digynous, trigynous, etc. (301) j and in the name
Cryptogamia, that of the 24th class, which is continued for the lower series
in the natural classification.

550. Natural System. A genuine system of botany consists of the
orders or families, duly arranged under their classes, and having the tribes,
the genera, and the species arranged in them according to their relation-
ships. This, when properly carried out, is the Natural System ; because
it is intended to express, as well as possible, the various degrees of relation-
ship among plants, as presented in nature ; that is, to rank those species
and those genera, etc., next to each other in the classification which are
really most alike in all respects, or, in other words, which are constructed
most nearly on the same particular plan.

551. There can be only one natural system of botany, if by this term
is meant the plan according to which the vegetable creation was called into
being, with all its grades and diversities among the species, as well of past
as ;Of the present time. But there may be many natural systems, if we
mean the attempts of men to interpret and express that plan, — systems
which will vary with advancing knowledge, and with the judgment and
skill of different botanists. These must all be very imperfect, bear the
impress of individual minds, and be shaped by the current philosophy of
the age. But the endeavor always is to make the classification answer to
Nature, as far as any system can which has to be expressed in a definite
and serial arrangement.

552. So, although the classes, orders, genera, etc., are natural, or as
natural as the systematist can make them, their grouping or order of
arrangement in a book, must necessarily be in great measure artificial.
Indeed, it is quite impossible to arrange the orders, or even the few classes,
in a single series, and yet have each group stand next to its nearest relatives
on both sides.

553. Especially it should be understood that, although phanerogamous

SECTION itt.J SYSTEM. 183

plants are of higher grade than cryptogamous, and angiospermous or or-
dinary phanerogamous higher than the gymnospermous, yet there is no
culmination in the vegetable kingdom, nor any highest or lowest order of
phanerogamous plants.

554. The particular system most largely used at present in the classi-
fication of the orders is essentially the following : —

SERIES I. PH ANEROGAMIA : PHANEROGAMOUS OR FLOWERING PLANTS.

CLASS I. DICOTYLEDONES ANGIOSPERME.E, called for shortness

in English, DICOTYLEDONS or DICOTYLS. Ovules in a closed ovary.

Embryo dicotyledonous. Stem with exogenous plan of growth. Leaves

reticulate-veined,

Artificial Division I. POLYPETAI^E, with petals mostly present and

distinct. Orders about 80 in number, Ranunculacea to Cornacece.
Artificial Division II. GAMOPETALJS, with gamopetalous corolla.

Orders about 45, Caprifoliaceae to Plantaginacece.
Artificial Division III. APETALE or INCOMPLETE, with perianth,
when present, of calyx only. Orders about 35 in number, from
Nyctaginaceee to Salicacea.

OLASS II. DICOTYLEDONES GYMNOSPERME^), in English GYM-
NOSPERMS. No ovary or pericarp, but ovules and seeds naked, and no
proper calyx nor corolla. Embryo dicotyledonous or polycotyledonous.

SECTION XIX. BOTANICAL WORK.

555. Some hints and brief instructions for the collection, examination,
and preservation of specimens are added. They are especially intended
for the assistance of those who have not the advantage of a teacher. They
apply to phanerogamous plants and Ferns only, and to systematic botany.1

§ 1. COLLECTION, OB HERBORIZATION.

556. As much as possible, plants should be examined in the living state,
or when freshly gathered. But dried specimens should be prepared for
more leisurely examination and for comparison. To the working botanist
good dried specimens are indispensable.

557. Botanical Specimens, to be complete, should have root or root-
stock, stem, leaves, flowers, both open and in bud, and fruit. Some-
times these may all be obtained at one gathering ; more commonly two or
three gatherings at different times are requisite, especially for trees and
shrubs.

558. la Herborizing, a good knife and a narrow and strong trowel are
needed ; but a very strong knife will serve instead of a trowel or small pick
for digging out bulbs, tubers, and the like. To carry the specimens, either
the tin box (yasculum) or a portfolio, or both are required. The tin box is
best for the collection of specimens to be used fresh, as in the class-room ;
also for very thick or fleshy plants. The portfolio is indispensable for long
expeditions, and is best for specimens which are to be preserved in the
herbarium.

559. The Vasculum, or Botanical Collecting-box, is made of tin, in shape
like a candle-box, only flatter, or the smaller sizes like an English sandwich-
case ; the lid opening for nearly the whole length of one side of the box.
Any portable tin box of convenient size, and capable of holding specimens
a foot or fifteen inches long, will answer the purpose. The box should shut
close, so that the specimens may not wilt : then it will keep leafy branches
and most flowers perfectly fresh for a day or two, especially if slightly
moistened. They should not be wet.

560. The Portfolio is best made of two pieces of solid binder's-board,
covered with enamel cloth, which also forms the back, and fastened by
straps and buckles. It may be from a foot to twenty inches long, from
nine to eleven or twelve inches wide. It should contain a needful quantity
of smooth but strong and pliable paper (thin so-called Manilla paper is
best), either fastened at the back as in a book, or loose in folded sheets
when not very many specimens are required. As soon as gathered, the
specimens should be separately laid between the leaves or in tba folded
sheets, and kept under moderate pressure in the closed portfolio.

SECTION 19.] HERBORIZATION. 185

561. Of small herbs, especially annuals, the whole plant, root and all,
should be taken for a specimen. Of larger ones branches will suffice, with
some leaves from near the root. Enough of the root or subterranean part
of the plant should be collected to show whether it is an annual, a
biennial, or a perennial. Thick roots, bulbs, tubers, or branches of speci-
mens intended to be pressed should be thinned with a knife, or cut into
slices. Keep the specimens within the length of fifteen or sixteen inches,
by folding, or when that cannot be done, by cutting into lengths.

562. For Drying Specimens a good supply of soft and unsized
paper is wanted; and some convenient means of applying considerable
pressure. To make good dried botanical specimens, dry them as rapidly
as possible between many thicknesses of sun-dried paper to absorb their
moisture, under as much pressure as can be given without crushing the
more delicate parts. This pressure may be had by a botanical press, of
which various forms have been contrived; or by weights placed upon a
board, — from forty to eighty or a hundred pounds, according to the
quantity of specimens drying at the time. Tor use while travelling, a
good portable press may be made of thick binders' boards for the sides,
and the pressure may be applied by strong straps with buckles. Still
better, on some accounts, are portable presses made of wire network,
which allow the dampness to escape by evaporation between the meshes.
For herborization in a small way, a light wire-press may be taken into
the field and made to serve also as a portfolio.

563. It is well to have two kinds of paper, namely, driers of bibulous
paper, stitched into pads (or the pads may be of thick carpet-paper, cut to
size) and thin smooth paper, folded once ; the specimens to be laid into the
fold, either when gathered or on returning from the excursion. These
sheets are to hold the specimens until they are quite dry. Every day, or
at first even twice a day, the specimens, left undisturbed in their sheets,
are to be shifted into fire-dried or sun-dried fresh driers, and the pressure
renewed, while the moist sheets are spread out to dry, so as to take their
turn again at the next shifting. This course must be continued until the
specimens are no longer moist to the touch. Good and comely specimens
are either made or spoiled within the first twenty-four or thirty-six hours.
After that, wheil plenty of driers are used, it may not be necessary to
change them so frequently.

664. Succulent plants, which long refuse to part with life and moisture,,
and Spruces and some other evergreens which are apt to cast oft" their
leaves, may be plunged for a moment into boiling water, all but the flowers.
Delicate flowers may be encased in tliin tissue paper when put into the press.
Thick parts, like the heads of Sun-flowers and Thistles, may be cut in two
or into slices.

565. Dried specimens may be packed in bundles, either in folded paper
or upon single half-sheets. It is better that such paper should not be
bibulous. The packages should be well wrapped or kept in close cases.

186 BOTANICAL WORK. [SECTION 19.

566. Poisoning is necessary if specimens are to be permanently pre-
served from the depredation of insects. The usual application is an almost
saturated solution of corrosive sublimate in 95 per cent alcohol, freely ap-
plied with a large and soft brush, or the specimens dipped into some of the
solution poured into a large and flat dish; the wetted specimens to be
transferred for a short time to driers.

§ 2. HERBARIUM.

567. The botanist's collection of dried specimens, ticketed with their
names, place, and time of collection, and systematically arranged under
their genera, orders, etc., forms a Hortm Siccus or Herbarium. It com.
prises not only the specimens which the proprietor has himself collected,
but those which he acquires through friendly exchanges, or in other ways.
The specimens of an herbarium may be kept in folded sheets of paper;
or they may be fastened on half-sheets of thick and white paper, either
by gummed slips, or by glue applied to the specimens themselves. The
former is best for private and small herbaria; the latter for large ones
which are much turned over. Each sheet should be appropriated to one
species ; two or more different plants should never be attached to the same
sheet. The generic and specific name of the plant should be added to
the lower right-hand corner, either written on the sheet, or on a ticket
pasted down; and the time of collection, the locality, the color of the
flowers, and any other information which the specimens themselves do
not afford, should be duly recorded upon the sheet or the ticket. The
sheets of the herbarium should all be of exactly the same dimensions.
The herbarium of Linnseus is on paper of the common foolscap size, about
eleven inches long and seven wide. This is too small. Sixteen and three
eighths inches by eleven and a half inches is an approved size.

568. The sheets containing the species of each genus are to be placed
in ffenm-covers, made of a full sheet of thick paper (such as the strong-
est Manilla-hemp paper), to be when folded of the same dimensions as the
species-sheet but slightly wider: the name of the genus is to be writ-
ten on one of the lower corners. These are to be arranged under the
orders to which they belong, and the whole kept in closed cases or cabi-
nets, either laid flat in compartments, like " pigeon-holes," or else placed
in thick portfolios, arranged like folio volumes. All should be kept, as
much as practicable, in dust-proof and insect-proof cases or boxes.

569. Fruits, tubers, and other hard parts, too thick for the herbarium,
may be kept in pasteboard or light wooden boxes, in a collection apart.
Small loose fruits, seeds, detached flowers, and the like may be conven.
iently preserved in paper capsules or envelopes, attached to the herbarium
thefts.

SECTION 19.] INVESTIGATION AND DETERMINATION. 187

§3. INVESTIGATION AND DETERMINATION OF PLANTS.

570. The Implements required are a hand magnifying glass, a pocket
lens of au inch or two focus, or a glass of two lenses, one of the lower
and the other of the higher power ; and a sharp penknife for dissection.
With these and reasonable perseverance the structure of the flowers and
fructification of most phanerogamous plants and Ferns can be made out.
But for ease and comfort, as well as for certainty and right training, the
student should have some kind of simple stage microscope, and under
this make all dissections of small parts. Without it the student will be
apt to fall into the bad habit of guessing where he ought to ascertain.

571. The simple microscope may be reduced to a good lens or doublet,
of an inch focus, mounted over a glass seage, so that it can be moved up
and down and also sidewise, and with (or without) a little mirror under-
neath. A better one would have one or two additional lenses (say x>f half
and of a quarter inch focus), a pretty large stage, on the glass of which
several small objects can be placed and conveniently brought under the
lens ; and its height or that of the lens should be adjustable by a rack-
work; also a swivel-mounted little mirror beneath, which is needed for
minute objects to be viewed by transmitted light.

572. For dissecting and displaying small parts on the stage of the
microscope, besides a thin-bladed knife, the only tools needed are a good
stock of common needles of various sizes, mounted in handles, and one or
more saddler's-needles, which, being triangular, may be ground to sharp
edges convenient for dissection. Also a pair of delicate-pointed forceps ;
those with curved points used by the dentist are most convenient. A
cup of clean water is indispensable, with which to moisten or wet, or
in which occasionally to float delicate parts. Small flowers, buds, fruits,
and seeds of dried specimens can be dissected quite as well as fresh ones.
They have only to be soaked in warm or boiling water.

573. The compound microscope is rarely necessary except in crypto-
gamic botany and vegetable anatomy ; but it is very useful and convenient,
especially for the examination of pollen. To the advanced botanist it is a
necessity, to all students of botany an aid and delight.

574. Analysis. A few directions and hints may be given. The most
important is this : In studying an unknown plant, make a complete ex-
amination of all its parts, and form a clear idea of its floral structure
and that of its fruit, from pericarp down to the embryo, or as far as the
materials in hand allow, before taking a step toward finding out its name
and relationship by means of the keys or other helps which the Manuals
and Floras provide. If it is the name merely that is wanted, the shorter
way is to ask some one who already knows it. To verify the points of
structure one by one as they happen to occur in an artificial key, without
any preparatory investigation, is a usual but is not the best nor the surest

18$ BOTANICAL WORK. [SECTION 19.

way. It is well to make drawings or outline sketches of the smaller parts,
and especially diagrams of the plan of the flower, such as those of Fig.
225, 227, 241, 244, 275-277. For these, cross sections of the flower-bud
or flower are to be made : and longitudinal sections, such as Fig. 270-274,
are equally important. The dissection even of small seeds is not difficult
after some practice. Commonly they need to be soaked or boiled.

575. The right appreciation of characters and terms used in description
needs practice and calls for judgment. Plants do not grow exactly by
rule and plummet, and measurements must be taken loosely. Difference
of soil and situation are responded to by considerable variations, and other
divergences occur which cannot be accounted for by the surroundings, nor
be anticipated in general descriptions. Annuals may be very depauperate
in dry soils or seasons, or very large when particularly well nourished.
Warm and arid situations promote, and wet ones are apt to diminish pubes-
cence. Salt water causes increased succulence. The color of flowers is
apt to be lighter in shade, and brighter in open and elevated situations.
A color or hue not normal to the species now and then occurs, which
nothing in the conditions will account for. A white-flowered variation q/
any other colored blossom may always be expected; this, though it may be
notable, no more indicates a distinct variety of the species than an albino
would a variety of the human species. The numerical plan is subject to
variation in some flowers ; those on the plan of five may now and then vary
to four or to six. Variations of the outline or lobing of leaves are so familiar
that they do not much mislead. Only wider and longer observation suf-
fices to prevent or correct mistakes in botanical study. But the weighing
of evidence and the balancing of probabilities, no less than the use of the
well-ordered and logical system of classification, give as excellent training
to the judgment as the search for the facts themselves does to the observing
powers.

} 4. SIGNS AND ABBREVIATIONS.

576. For a full account of these, whether of former or actual use, see
" Structural Botany " of the " Botanical Text Book," pp. 367, 392, as also
for the principles which govern the accentuation of names. It is needful
here to explain only those used in the Manuals and Floras of this country,
for which the present volume is an introduction and companion. They
are not numerous.

577. In arranging the species, at least those of a large genus, the divi-
sions are denoted and graduated as follows : The sign § is prefixed to sec-
tions of the highest rank : these sections when they have names affixed to
them (as PRUNUS § CERASUS) may be called subgenera. When the divi-
sions of a genus are not of such importance, or when divisions are made
under the subgenus itself, the most comprehensive ones are marked by as-
terisks, * for the first, * * for the second, and so on. Subdivisions are

SECTION 19.] SIGNS AND ABBBEVIATIONS. 189

marked with a prefixed •+- ; those under this head with -M- ; and those,
under this with =, if there be so many grades. A similar notation is fol-
lowed in the synopsis of the genera of an order.

578. The interrogation point is used in botany to indicate doubt. Thus
Clematis crispa, L. ? expresses a doubt whether the plant in question is
really the Clematis crispa of Linna3us. Clematis ? polypetala expresses
a doubt whether the plant so named is really a Clematis. On the other
hand the exclamation point (!) is used to denote certainty whenever there
is special need to affirm this.

579. Tor size or height, the common signs of degrees, minutes, and
seconds, have been used, thus, 1°, 2', 3", stand respectively for a foot,
two inches, and three lines or twelfths of an inch. A better way, when
such brevity is needed, is to write lft. 2ta. 31.

580. Signs for duration used by Linnseus were Q for an annual, $ for
a biennial, 2£ for a perennial herb, 5 f°r a shrub or tree. DeCandolle
brought in 0 for a plant that died after once flowering, (l) if annual, ®
if biennial.

581. To indicate sexes, 5 means staminate or male plant or blossom;
9 , pistillate or female ; g , perfect or hermaphrodite.

582. To save room it is not uncommon to use oo in pi ace of "many;" thus,
" Stamens oo," for stamens indefinitely numerous : "co flora " for pluriflora
or many-flowered. Still more common is the form " Stamens 5-20," or
" Calyx 4-5-parted," for stamens from five to twenty, calyx four-parted or
five-parted, and the like. Such abbreviations hardly need explanation.

583. The same may be said of such abbreviations as Cat. for calyx,
Cor. for corolla, Pet. for petals, St. for stamens, Pist. for pistil, Had. for
habitat, meaning place of growth, Herb, for herbarium, Hort. for garden.
Also L c., loco citato, which avoids repetition of volume and page.

584. "Structural Botany" has six pages of abbreviations of the names
of botanists, mostly of botanical authors. As they are not of much
consequence to the beginner, while the more advanced botanist will know
the names in full, or know where to find them, only a selection is here
appended*

PREFACE TO THE FIRST EDITION.

THIS book is intended to furnish botanical classes and beginners
generally with an easier introduction to the plants of this country
than the Manual, and one which includes the common cultivated as
well as the native species. It is made more concise and simple, first,
by the use of somewhat less technical language ; second, by the omis-
sion, as far as possible, of the more recondite and, for the present
purpose, less essential characters; and also of most of the obscure,
insignificant, or rare plants which students will not be apt to meet
with or to examine, or which are quite too difficult for beginners ;
such as the Sedges, most Grasses, and the crowd of Golden Rods,
Asters, Sunflowers, and the like, which require very critical study.
On the other hand, this small volume is more comprehensive than
the Manual, since it comprises the common herbs, shrubs, and trees
of the Southern as well as the Northern and Middle States, and all
which are commonly cultivated or planted, for ornament or use, in
fields, gardens, pleasure grounds, or in house culture, including even
the conservatory plants ordinarily met with.

It is very desirable that students should be able to use exotic as
well as indigenous plants in analysis; and a scientific acquaintance
with the plants and flowers most common around us in garden, field,
and greenhouse, and which so largely contribute to our well-being
and enjoyment, would seem to be no less important than in the case
of our native plants. If it is worth while so largely to assemble
around us ornamental and useful trees, plants, and flowers, it is cer-
tainly well to know what they are and what they are like. To stu-
dents in agricultural schools and colleges this kind of knowledge will
be especially important.

One of the main objects of this book is to provide cultivators,
gardeners, and amateurs, and all who are fond of plants and flowers,
with a simple guide to a knowledge of their botanical names and

structure. There is, I believe, no sufficient work of this kind in the
English language, adapted to our needs, and available even to our
botanists and botanical teachers — for whom the only resource is to a
botanical library beyond the reach and means of most of these, and
certainly quite beyond the reach of those whose needs I have here
endeavored to supply, so far as I could, in this small volume. The
great difficulties of the undertaking have been to keep the book within
the proper compass, by a rigid exclusion of all extraneous and unneces-
sary matter, and to determine what plants, both native and exotic, are
common enough to demand a place in it, or so uncommon that they
may be omitted. It is very unlikely that I can have chosen wisely in
all cases and for all parts of the country, and in view of the different
requirements of botanical students on the one hand and of practical
cultivators on the other — the latter commonly caring more for
made varieties, races and crosses, than for species, which are the
main objects of botanical study.

But I have here brought together, within less than 350 pages, brief
and plain botanical descriptions or notices of 2650 species, belonging
to 947 genera ; and have constructed keys to the natural families, and
analyses of their contents, which I hope may enable students, who
have well studied the First Lessons, to find out the name, main char-
acters, and place of any of them which they will patiently examine in
blossom, and, when practicable, in fruit also. If the book answers
its purpose reasonably well, its shortcomings as regards cultivated
plants may be made up hereafter. As to the native plants omitted,
they are to be found, and may best be studied, in the Manual of the
Botany of the Northern United States, and in Chapman's Flora of the
Southern United States.

This book is designed to be the companion of the First Lessons in
Botany, which serves as grammar and dictionary ; and the two may
be bound together into one compact volume, forming a comprehensive
School Botany.

For the account of the Ferns, and the allied families of Cryptoga-
mous Plants I have to record my indebtedness to Professor D. C.
Eaton of Yale College. These beautiful plants are now much cul-
tivated by amateurs; and the means here so fully provided for
studying them will doubtless be appreciated.

PREFACE TO THE REVISION.

THREE motives have dominated the course of this revision ; First,
to preserve, so far as possible, the method of the original ; it is still
Asa Gray's botany, and the reviser has attempted nothing more
than to bring it down to date. Second, it is a companion to the
Manual, and, therefore, the nomenclature is made to conform strictly
with that volume ; and the authorities have been added for the purpose
of identifying the names, and to distinguish them from other systems
of nomenclature which are now advocated. Third, it is primarily a
school book, and there has been no attempt to include either all the
wild or all the cultivated plants of its territory, but rather to consider
those species which are most readily accessible for demonstration,
and which are most likely to attract the attention of a beginner in
botany. If it is said that many conspicuous wild plants are omitted,
the reviser will answer that all such plants are described in the
Manual, and Chapman's Flora of the Southern States, while there is no
other account of our domesticated flora. Therefore, in cases of doubt
as to the relative importance, to this volume, of wild and cultivated
species, the cultivated rather than the native plants have been inserted.

A preliminary draft of this revision, through the family Legumi-
nosae, was made by Professor Charles R. Barnes, of the University of
Wisconsin, of which I have been glad to avail myself.

SIGNS AND EXPLANATIONS.

THE SIGNS AND ABBREVIATIONS employed in this work are few. The
signs are : —

(f) for an annual plant.
(2) for a biennial plant.
H for a perennial plant.

The signs for degrees, minutes, and seconds are used for feet, inches,
and lines, the latter twelve to the inch. ' Thus 1° means a foot in length
or height, &c. ; 2', two inches ; 5", five lines, or five-twelfths of an inch.

The dash between two figures, as 5- 10 means from five to ten, &c.

The character co means many.

Fl. stands for flowers or flowering.

Cult, stands for cultivated.

Nat. stands for naturalized.

N., E., S., W. stand for North, East, South, and West.

The geographical abbreviations, such as Eu. for Europe, and the com-
mon abbreviations for the names of the States, need no particular expla-
nation.

Species printed in heavy-faced Roman type are indigenous to some
part of our territory (the U. S., East of the 100th meridian).

Those in heavy-faced Italic type are not indigenous to this territory, and
they exist in our region only in cultivation or as introduced weeds.

The species and varieties in SMALL CAPITAL KOMAN LETTERS are hor-
ticultural forms or hybrids. When in parenthesis, they are simply
synonyms.

Pronunciation. — In accordance with the usage in Gray's botanies, it
is intended that the Latin names in this volume shall be pronounced after
the English method. The accent marks designate both the accentuation
(or most emphatic syllable), and the length of the vowel. The grave (')
designates a long vowel, and the acute (') a short one. The letters 01,
like to, representing the Greek ending -oddrjs, should properly be pro-
nounced separately. If the i, in this case, is the penultimate syllable
(next to the last), it should be pronounced long, as inprino-ides, usneo-
ides ; but if it is the antepenultimate (third syllable from the end) , it is
pronounced short, as rhomb o -idea. In names derived from dioicus and
* (dioecious and monoecious), bi is a true diphthong, as in choice.
27

28 STATISTICS.

The diphthong au is given its customary English sound. The pupil should
bear in mind that the final e in the names of plants should always be
pronounced (taking the sound of short f)» a* in officina-le, vulga-re,
commu-ne.

NOMENCLATURE.

THE first part of the name of a plant designates the genus to
which it belongs, or is generic; the second part belongs to the
particular species, or is specific; but both words are necessary
for the designation of the plant or species. The literature of
systematic botany is so voluminous, however, that, in order to
identify the plant names and to aid in tracing them to their
origins, it is necessary to cite the author of the name along with
the name itself. In accordance with the method in Gray's
botanies, this author is understood to be the one who first used
the two names together ; that is, he is the author of the com-
plete name or combination and not necessarily of either part
of it. The full names of the authors most frequently cited in

SERIES I.

FLOWERING OR PELENOGAMOUS PLANTS.

Plants bearing true flowers ; that is, having stamens and
pistils, and producing seeds containing an embryo.

CLASS I. ANGIOSPERMS.

Plants having a closed ovary which contains the ovules :
includes all but the Pine and Cycas families.

SUBCLASS I. DICOTYLEDONS (or EXOGENS).

Distinguished by having the woody strands of the stem
in a circle around a pith ; the wood often increasing by
yearly layers when the stem is more than one year old ;
the embryo with a pair of cotyledons or seed leaves;
leaves generally net-veined ; parts of the flower seldom
in threes, most commonly in fives or fours. See Lessons,
pp. 23, 139. This class includes all our ordinary trees and
shrubs, and the greater part of our herbs.

I. POLYPETALOUS DIVISION.

Includes the families which have, at least in some
species, both calyx and corolla, the latter with the petals
not united with each other. Yet some plants of almost all
these families have apetalous flowers, and in some species
the petals are more or less united.

34 CROWFOOT FAMILY.

I. BANUNCULACEjE, CROWFOOT FAMILY.

Not perfectly distinguished by any one or two particular
marks, but may be known, on the whole, by having numerous
stamens, and usually more than one pistil, all the parts of the
flower distinct, and inserted on the receptacle. The calyx is
often colored like a corolla, when the latter is wanting. The
bulk of the seed is hard albumen, the embryo being very small.
The plants are herbs with an acrid watery juice (not milky or
colored), or a few barely shrubby. Many are cultivated for
ornament.

Aquatic, perennial herbs, from strong, horizontal rootstocks,
with the leaves which float on the surface of the water or rise
above it mostly peltate or roundish heart-shaped (dissected
and immersed in No. 1), their margins in- rolled in the bud,
long-petioled ; axillary 1-flowered peduncles ; sepals and petals
hardly ever 5, the latter usually numerous and imbricated in
many rows. The genera differ so widely in their botanical
characters that they must be described separately. One of
them is the famous Amazon Water Lily, VICTORIA REGIA, with
floating leaves, 3 feet or more in diameter, and the magnificent
flowers almost in proportion ; while the dull flowers of Water-
Shield are only half an inch long.

52 WATER LILY FAMILY.

§ 2. Sepals andpetais numerous, in several rows and passing into each other. Sta*
mens many. Pistils several, each sunken in the obconical and nearly flat-topped
receptacle, the imbedded nut-like fruits appearing like seeds in separate open
cells.

8. NELUMBO. Upper part of the receptacle enlarged into a top-shaped body, bearing a
dozen or more ovaries, each tipped with a flat stigma and separately immersed in as
many hollows. (Lessons, p. 113, Fig. 362.) In fruit these form 1-seeded nuts, resem-
bling small acorns. The whole kernel of the seed is embryo, a pair of fleshy and fari-
naceous cotyledons inclosing a plumule of 2 or 3 rudimentary green leaves.
§3. Sepals 4-6. Petals and stamens numerous in many rows. Pistil 1, compound.

4. NYMPH^A. Sepals 4, green outside. Petals numerous, many times 4, passing some-

what gradually into the numerous stamens (Lessons, p. 84, Fig. 228) ; both organs
grow attached to the globular many-celled ovary, the former to its sides which they
cover, the latter borne on its depressed summit. Around a little knob at the top of
the ovary the numerous stigmas radiate as in a poppy-head, ending in long and narrow
incurved lobes. Fruit like the ovary enlarged, still covered by the decaying persistent
bases of the petals ; numerous seeds cover the partitions. Kipe seeds each in an aril-
lus, or bag, open at the top. (Lessons, p. 126, Fig. 418.) Embryo, like that of Nelumbo
on a very small scale, but inclosed in a bag, and at the end of the kernel, the rest of
which is mealy albumen.

5. NUPHAK. Sepals usually 6 or 5, partly green outside. Petals many small and thickish

bodies inserted under the ovary along with the very numerous short stamens. Ovary
naked, truncate at the top, which is many-rayed by stigmas, fleshy in fruit ; the inter-
nal structure as in Nymphaea, only there is no arillus to the seeds.

BEAN of the Orient, now commonly cult., has pink flowers and blunt
anthers, and the high flower and leaf-stalks studded with prickly warts.

4. NYMPHJEA, WATER LILY, POND LILY. (Dedicated to the
water nymphs.) Long prostrate rootstocks, often as thick as one's
arm, send up floating leaves (rounded and with a narrow cleft nearly
or quite to the petiole) and large handsome flowers, produced all sum-
mer ; these close in the afternoon ; the fruit ripens under water.

sepals, 4 petals, with their upper part generally spreading above
the calyx in the form of a cross) ; tetradynamous stamens
(i.e. 6, 2 of them shorter than the other 4 ; rarely 4 or 2) ; a
single 2-celled pistil with 2 parietal placentae, forming in
fruit a silique, or when short a silicle. (See Lessons, Figs.
235, 236, for the flower, Figs. 401-403 for the fruit, and Figs.

has the radicle bent against the cotyledons. Flowers in ra-
cemes, which are at first short, like simple corymbs, but
lengthen in fruiting ; no bracts below the pedicels. The blos-
soms are all nearly alike throughout the family ; so that the
genera are mainly known by the fruit and seed, which are,
therefore, indispensable and may usually be had before all
tjie flowers l^ave passed.

yellow, sweet-scented small blossoms, on slender peduncles, all winter and
spring ; a sort of woody perennial, with slender and spreading or hang-

characterized as a whole in any short and easy way, including
as it does Geraniums, Nasturtiums, Wood Sorrels, Balsams,
etc.,which have to be separately described.

§ 1. Flowers regular ; leaves simple, variously lobed or even dissected ; glands of the
disk 5, alternate with the petals. Herbs.

* Sepals imbricate,- ovary 5-celled, \0-ovuled; fruit dehiscent, the \-seeded carpels

splitting elastically from a prolonged axis. (Lessons, Figs. 353, 359.)

1. GERANIUM. Flowers 5-merous ; sepals usually slender-pointed; stamens with

anthers 10 (rarely 5) ; the recurving bases of the styles or tails of the carpels in fruit
naked inside. Leaves with stipules. Herbage scented.

2. EROD1UM. Stamens with anthers only 5. Styles when they split off from the beak,

bearded inside, often twisting spirally ; otherwise as Geranium.

* * Sepals valvate; ovary 5-celled, 5-ovuled ; the carpels fleshy and indehiscent, break'

ing away from a very short axis ; leaves pinnately divided.

8. LIMNANTHES. Sepals and petals 5, the latter convolute in the b,.d. Stamens 10,
separate at the base. Style 1, 5-lobed at the apex, rising from the center of thrf
5 ovaries, which in fruit become thickish and warty nutlets.

4. FLCERKEA. Sepals, small petals, stigmas, and lobes of the ovary 8 ; and stamens 6;

otherwise like Limnanthes.

§ 2. Flowers regular; leaves compound, of 3 obcordate leaflets ; disk glands 0. Herbs.

5. OXALIS. Sepals and petals 5, the former imbricated, the latter convolute in the bud.

Stamens 10, monadelphous at base, the alternate ones shorter. Styles 5, separate on
a 5-celled ovary, which becomes a membranaceous several-seeded pod. Juice sour
and watery. Flowers usually open only in sunshine.

§ 3. Flowers somewhat irregular, Geranium like, the base of one sepal extending down'
ward on one side of the pedicel, forming a narrow tube or adherent spur.
Shrubby or fleshy stemmed.

6. PELARGONIUM. Sepals and petals 5 ; the two petals on the upper side of the flower

differing from the rest more or less in size or shape. Stamens with anthers fewer than
10, commonly 7. Pistil, etc., as in Geranium. Herbage scented. Leaves with stipules.

§4. Flowers very irregular, and unsymmetrical ; spur free. Tender herbs.

7. TROP^EOLUM. Sepals 5, united at the base, and on the upper side of the flower ex-

tended into a long, descending spur. Petals 5, or sometimes fewer, usually with claws ;
the two upper more or less different from the others and inserted at the mouth of the
spur. Stamens 8, unequal or dissimilar; filaments usually turned downwards and
curving. Ovary of 3 lobes surrounding the base of a single style, in fruit becoming
8 thick and fleshy closed, separate carpels, each containing a single large seed. Herbs,
often climbing by their long leafstalks ; the watery juice with the pungent odor and
taste of Cress. Leaves alternate ; stipules none or minute. Peduncles axillary, 1-
flowered.

8. IMPATIENS. Sepals and petals similarly colored, the parts belonging to each not

readily distinguished. There are 2 small outer pieces, plainly sepals, on the sides of
the flower ; then below (as it hangs, but really on the upper side) a third sepal form-

94 GERANIUM FAMILY.

hig a large sac contracted at the bottom into a spur or little tail ; opposite the sac
is a notched petal, and within are 2 small, unequally 2-lobed petals, one each side of
the sac ; these each represent 2 united, petals. Stamens 5, short, conniving or lightly
cohering around and covering the 5-celled ovary, which in fruit becomes a several-
seeded pod ; this bursts elastically, flying in pieces at the touch, scattering the seeds,
separating into 5 twisting valves and a thickish axis. Style none. Seeds rather large.
Erect, branching, succulent-stemmed herbs, with simple leaves and no stipules.

116 PULSE FAMILY.

XXXVI. LEGUMINOS^E, PULSE FAMILY,

Distinguished by the papilionaceous corolla (Lessons, Figs.
261, 262), usually accompanied by 10 monadelphous or diadel-
phous or rarely distinct stamens (Lessons, Figs. 287, 288) and
the legume (Lessons, Figs. 393, 394). These characters are
combined in the proper Pulse Subfamily. In the two other
great divisions the corolla becomes less papilionaceous or
wholly regular. Alternate leaves, chiefly compound, entire
leaflets, and stipules, are almost universal in this great family.

I. PULSE SUBFAMILY. Flower (always on the plan
of 5, and stamens not exceeding 10) truly papilionaceous, i.e.
the standard outside of and in the bud enwrapping the other
petals, or only the standard present in Amorpha. (For the
terms used to denote the parts of this sort of corolla, see
Lessons, p. 91.) Sepals united more or less into a tube or
cup. Leaves never twice compound, alternate in mature plants.

A. Stamens separate to the base. (Plants not twining or climbing.)
* Leaves simple or of 3 digitate leaflets.

1. CHORIZEMA. Somewhat shrubby, with simple and spiny-toothed leaves, scarcely any

stipules, and orange or copper-red flowers. Standard rounded, kidney-shaped ; keel
straight, much shorter than the wings. Pod ovoid, turgid, several-seeded.

2. BAPT1SIA. Herbs, with simple entire sessile leaves and no stipules, or mostly of 3

leaflets with deciduous or persistent stipules. Flowers yellow, blue, or white.
Standard erect, with the sides turned back, about equaled by the oblong and straight-
ish wings and keel. Pod inflated, coriaceous, stalked in the calyx, many-seeded.

3. THEKMOPSIS. Pod linear, flat. Flowers yellow. Leaflets obovate or oblong. Other-

wise as Baptisia. * * Leaves odd-pinnate.

4. CLADRASTIS. Trees, with large leaflets, no obvious stipules, and hanging terminal

panicles of white flowers. Standard turned back ; the nearly separate straightish
keel-petals and wings oblong, obtuse. Pod short-stalked in the calyx, linear, very
flat, thin, marginless, 4-6-seeded. Base of the petioles hollow and covering the
axillary leaf-buds of the next year.

5. SOPHORA. Trees, shrubs, or herbs, with numerous leaflets, and mostly white or yel-

low flowers in terminal racemes or panicles. Keel-petals and wings oblong, obtuse,
usually longer than the broad standard. Pod commonly stalked in the calyx, terete,
several-seeded, fleshy or almost woody, hardly ever opening, but constricted across
into mostly 1-seeded portions.

B. Stamens monadelphous or diadelphous.

§ 1. Herbs, shrubs, or one a small tree, never twining, trailing, or tendril bearing,
with leaves simple or of 3 or more digitate leaflets^ monadelphous stamens, and
the alternate 3 anthers differing in size and shape from the other 5; pod
usually several-seeded.

ROSE FAMILY.

XXXVII. ROSACES, ROSE FAMILY.

Trees, shrubs, or herbs with alternate stipulate leaves and
regular flowers, with usually indefinite unconnected stamens
inserted on the calyx, one, few, or many simple separate pistils
(except in the division to which the Pear belongs), and single,
few, or occasionally numerous seeds ; these filled with a.
straight embryo. Calyx usually of 5 sepals, but sometimes
reinforced by a row of sepal-like bracts beneath. Petals as
many as the sepals, or sometimes wanting. Destitute of
noxious qualities (excepting the bark, leaves, and kernels of
some Cherries, the Almond, etc.), and furnishing the most
important fruits of temperate climates, as well as the queen of
flowers. We have three principal great divisions.

I. ALMOND or PLUM SUBFAMILY ; consists of trees
or shrubs, with simple leaves, stipules free from the petiole
(often minute or early deciduous, so that there may appear to
be none), a calyx which is deciduous after flowering, and a
single pistil, its ovary superior and tipped with a slender style
(Lessons, p. 95, Fig. 271), containing a pair of ovules, and
becoming a simple drupe or stone-fruit. (Lessons, p. 120,
Fig. 375.)

1. PKUNUS. Calyx with a bell-shaped or urn-shaped tube and 5 spreading lobes. Petals

5, and stamens 3-5 times as many, or indefinitely numerous, inserted on the throat
of the calyx. Flowers white or rose-color.

II. EOSE SUBFAMILY PROPER: consists of herbs or
shrubs, with stipules either free from or united with the base
of the petiole, calyx persisting below or around the fruit,
which is composed of sometimes one, but commonly several or
many distinct pistils.

§ 1. Calyx not a fleshy tube or cup, nor closed over the fruit.

* Ovaries about 5 (2-12), becoming little pods, mostly several-(l-lQ-) seeded ; calyx with
only 5 or rarely 4 lobes.

2. SPIK^EA. Shrubs or perennial herbs, with stipules sometimes minute or obsolete,

sometimes conspicuous, and white or rose-purple, sometimes dioecious flowers.
Calyx open and short, mostly 5-cleft, not inclosing the pods. Petals equal, com-
monly broad. Stamens 10-50. Pods not inflated, 1-valved. Seeds linear.

3. PHYSOCARPUS. Shrubs, differing from Spiraea by inflated 2-valved pods, and round-

ish seeds.

4. EXOCHORDA. Shrubs with large white flowers, 5 bony 2-valved carpels joined to a

common axis, each with one large flat winged seed.

142 ROSE FAMILY.

5. GILLENTA. Herbs, with nearly white flowers and almost sessile leaves of 3 leaflets.

Calyx narrow, oblong, 5-toothed, enclosing the 5 pistils (which at first lightly cohere

§ 3. EVERGREEN ROSES; naturalized in the Southern States from China;
flowering in spring ; the flowers not double.

R. Icevigata, Michx. (or R. SfNiCA of Aiton). CHEROKEE ROSE. Planted
for garden hedges, etc., also run wild S. ; disposed to climb high, armed
with strong hooked prickles, very smooth, with bright green and glossy
evergreen leaves of mostly only 3 leaflets, and single flowers at the end
of the branches, with bristly calyx cup and large pure- white petals.
Occasional in greenhouses N.

R. bracteata, Wendl. BRACTED ROSE. In hedges far S., not common ;
has downy branches armed with strong, hooked prickles, 5-9 roundish
leaflets, and single large white flowers on very short peduncle, the calyx
covered by leafy bracts.

§ 4. EXOTIC GARDEN ROSES proper ; from Europe and Asia. Merely the
principal types ; the greater part of the modern garden roses much
mixed by crossing and changed by variation.

long, rambling shoots, or disposed to climb.

R. sempervirens, Linn. EVERGREEN ROSE, of S. Not hardy or hold-
ing its leaves N. ; with coriaceous, bright-green, oblong leaflets, curved
prickles, and nearly solitary white flowers, not double. The AYRSHIRE
ROSE is evidently 'an offshoot of R. arvensis, a closely related species.

R. multiflbra, Thunb. MANY-FLOWERED ROSE. A well-known half-
climbing species, from Japan and China, hardy in Middle States, with
branches, peduncles, and calyx more or less tomentose ; 5 or 7 soft and
somewhat rugose leaflets, slender, scattered prickles, and full corymbs of
small flowers, white, pale red, or rose-purple, not sweet-scented. The
double form is an old garden rose, but the single form is not common.
The POLYANTHA ROSES are offshoots of this, chiefly through hybridization
with Rosa Indica.

158 ROSE FAMILY.

R. moschata, Mill. MUSCAT or MUSK ROSE. Not climbing, with slender
curved prickles ; leaves of 5 or 7 lanceolate and pointed leaflets, a
corymb of white flowers, with a yellowish base to the petals, very sweet
scented, especially at evening.

mostly 3 (3-5) rather coriaceous and shining leaflets.

R. Indica, Linn. INDIA or CHINA ROSES. Includes the TEA, PERPETUAL
or BENGAL, BOURBON, and NOISETTE ROSES ; and the BENGAL POMPONS,
etc., are miniature forms of similar origin. A plant of upright habit,

or with a few purplish spines, hispid peduncles, erect and solitary
blush flowers, and a more or less pendulous, orange-red, oblong or obovate
fruit. The BOURSALT ROSES are derived from this, probably crossed with
the China Rose, and are mostly smooth-stemmed plants of somewhat
climbing habit and large double flowers.

edges, peduncle and calyx clammy, with odorous glands, the hip bristly
and glandular ; the flowers mostly nodding, large, and full-double, rose-
purple, or of various shades, rarely white ; fruit oblong. POMPON ROSES
are miniature varieties. Moss ROSES are abnormal states (var. Musc6sA)
with the glands and bristles of the calyx and peduncle developed into a
moss-like substance. Petals used for rose-water, essence of roses, etc.

R. Damascena, Mill. DAMASK ROSE. Known from the foregoing by
the greener bark, larger curved prickles, corymbed flowers oblong in the
bud, and with the long sepals (some of them pinnatifid or lobed) reflexed
during flowering, the hip oblong and pulpy ; petals rose-purple, white,
etc. ; used in preference for attar-of-roses and rose-water. HYBRID PER-
PETUAL ROSES are largely derived from this through hybridization with
forms of R. Indica and others.

MYKTLE FAMILY. 175

XLIII. HALORAGE^l, WATER MILFOIL FAMILY.

Contains a few insignificant aquatic or marsh plants, with
very small greenish flowers, sessile in the axils of the (often
whorled) leaves or bracts, a single ovule and seed suspended
in each of the 1-4 cells of the ovary, and 1-8 stamens ; all of
, them too obscure and unimportant for record here. The
species are fully treated in the Manual.

XLIV. MYRTACE^E, MYRTLE FAMILY.

Trees or shrubs, with simple, entire, and mostly aromatic
leaves, punctate with pellucid or resinous dots, no stipules,
perfect flowers, calyx-tube adherent to the ovary, its throat,
or a disk bordering it, bearing the petals and numerous
stamens ; style and stigma single. A large family in the
tropics and southern hemisphere, here commonly known only
by a few house-plants, or grown for fruit or ornament far S.,
which may be briefly noted as follows : —

1. Myrtus communis, Linn. COMMON MYRTLE. From the Mediter-
ranean region ; smooth, with ovate or lance-ovate, opposite, shining
leaves, small in the variety usually cultivated ; peduncles in their axils
bearing a small white or rose-tinged flower (sometimes full double), fol-
lowed by a black berry, containing several kidney-sliaped seeds.

2. Eugenia Jdmbos, Linn. ROSE APPLE. From India ; smooth, with
opposite, shining, long, and lanceolate leaves, and clusters of large white
flowers, with their long stamens most conspicuous ; the calyx tube
dilated and prolonged beyond the ovary, which forms a large edible
berry, like a small apple, scentless, but when eaten, of a rose-like savor ;
seeds very few, large.

3. Psidium Guyava, Linn. GUAVA. With oval, feather-veined, opposite
leaves, pubescent beneath, and one or two white flowers at the end of an
axillary peduncle ; the fruit a large and pear-shaped yellowish berry,
which is edible, and from which G-uava jelly is made in the West Indies.
The WHITE, PEAR, and APPLE GUAVAS are of this species. P. POMf-
FERUM and P. PYR^FERUM are forms of this species. The plant is prob-
ably native to tropical America, although now widely distributed.

P. Catt/eianum, Sabine. CATTLEY GUAVA. Has obovate, and thick,
and shining leaves, and a small reddish fruit, which lacks the muskiness
of the common sorts.

4. Callistemon lanceoldtus, Sweet. Of Australia, called BOTTLE BRUSH,
on account of the appearance of the flowers (sessile all round the stem
below the later leaves) with their very long, deep red stamens ; the 5
petals small and falling early ; the fruit a small, many-seeded pod, open-
ing at the top; the alternate lanceolate leaves remarkable for being
turned edgewise by a twist at their base, as in many related Myrtaceous
plants of Australia.

threads ; flower tube flaring, the lobes pointed and erect.

C. Pepo, Linn. PUMPKIN. Cult., as now, along with Indian Corn, by
the North American Indians before the coming of the whites. The chief
types are: the common FIELD PUMPKIN used for pies and fed to stock ;
the BUSH SCALLOP SQUASHES with white or yellow fruit flattened endwise
and the vines scarcely running ; the SUMMER CROOK-NECK or WARTY
SQUASHES, with white or yellow J-shaped fruits, and vines seldom run-
ning ; the GOURDS, small, very hard-shelled fruits of many shapes and
colors borne on slender running vines.

length or breadth, the hard flesh yellow or orange. The crowned or
TURBAN SQUASHES have the top of the fruit projecting beyond an encir-
cling line or constriction which marks the margin of the adherent calyx
tube. Here belong the best fall and winter squashes, as HUBBARD,
BOSTON MARROW, etc.

1. BEGONIA, ELEPHANT'S EAR, BEEFSTEAK GERANIUM.

(Named for M. Begon, Governor of St. Domingo 200 years ago.)
Flowers with the calyx and corolla colored alike, sometimes dull but
usually handsome, both kinds commonly in the same cyme, and flat in

cluster of numerous stamens with short filaments ; in the fertile are 3
styles with thick or lobed stigmas. Ovary and pod triangular, often
3-winged. These curious plants are remarkable for the beauty of the
leaves of many species, as well as for flowers of many colors and
patterns. There are very many species and hybrids. Following are
some of the commonest : —

I. TUBEROUS BEGONIAS. Low or even stemless plants, arising from a .
bulb-like tuber, and bearing very large (2'-4' across) showy 'flowers,

200 PARSLEY FAMILY.

LIV. UMBELLIFEBJE, PARSLEY FAMILY.

Herbs, some innocent and many of them aromatic, others
acrid-narcotic poisons, with small flowers in umbels, calyx
adherent to the 2-celled ovary, which has a single ovule hang-
ing from the summit of each cell, 5 minute calyx teeth or
none, 5 petals, 5 stamens, and 2 styles ; the dry fruit usually
splitting into 2 seed-like portions or akenes ; seed with hard
albumen and a minute embryo. Eryngium and one or two
others have the flowers in heads instead of umbels. Stems
usually hollow. Leaves alternate, more commonly compound
or decompound. Umbels mostly compound; the circle of
bracts often present at the base of the general umbel is called
the involucre; that at the base of an'umbellet, the involucel.
The flowers are much alike in all, and the characters are taken
from the form of the fruit, and much stress is laid upon the
receptacles of aromatic oil (vittce or oil tubes) which are found
in most species and give characteristic flavor. The family is
too difficult for the beginner ; so that only the common culti-
vated species, and the most conspicuous or noteworthy wild
ones are given here.

2. SANICULA. Flowers greenish or yellowish, so short-stalked or nearly sessile that the

umbellets appear like little heads, each with some perfect and fertile and some
staminate flowers. Fruits ovoid or globular, not readily splitting in two, not ribbed,
completely covered with short, hooked prickles. Leaves palulately parted.

3. DAUCUS. Flowers white or cream-color, in a regular compound umbel ; the petals

unequal, or those of the marginal flowers larger. Prickles in rows on the ribs o/
the short fruit, which splits in two when ripe. Leaves pinnately compound or
decompound.

§ 3. Fruits naked (not prickly) , splitting when ripe and dry into two one-seeded pieces
or carpels, each usually with 5 ribs or some of them may be wings. Fruits
mostly with oil tubes in the form of lines or stripes one or more in the intervals
between the ribs, and some on the inner face, sometimes also under the ribs,

* Fruit wingless.
+- Marginal flowers larger and irregular.

4. CORIANDRUM. Fruit globular, not readily splitting in two, indistinctly many-ribbed ;.

family, — from which it differs in the separate stamens, hang-
ing seed, etc. All are natives of the Old World.

1. DIPSACUS. Coarse and stout herbs, with stems and midrib of leaves often prickly,

and the heads with rigid prickly-pointed bracts or chaff under each flower, under the
whole a conspicuous leafy involucre. Each flower has an involucel in the form of a
little calyx-like body inclosing the ovary and akene. Calyx continued beyond the
ovary into a mere truncate, short cup-like, border. Corolla slender, with 4 short
lobes. Stamens 4. Style slender.

2. SCABIOSA. Less coarse, not prickly ; the short heads surrounded by a softer green

involucre ; a short scale or soft bristle for a bract under each flower. Corolla funnel-
form, 4-5-cleft, oblique or irregular ; the outer ones often enlarged. Stamens 4.
Style slender. Involucel inclosing the ovary and the calyx various.

1. DIPSACUS, TEASEL. (Greek: to thirst; the united bases of the
leaves in some species catch rain water.) Flowers summer.

D. sy/Kesfr/s, Mill. Stem 4°-5° high, prickly, with lance-oblong leaves,
the upper ones united round the stem ; heads large, oblong ; corollas pur-
plish or lilac ; slender-pointed, straight chaff under each flower, (g)
Along roads.

D. Fullbnum, Linn. FULLER'S T. Less prickly than the other, with
involucre hardly longer than the flowers, the awn-like tips of the rigid
chaff hooked at the end, which makes the teasel useful for carding
woollen cloth ; cultivated in central N. Y. for this purpose, sometimes
escaping into waste places and roadsides. (2)

2. SCABIOSA, SCABIOUS. (Latin name.) Flowers summer. One
European species is commonly cultivated for ornament, —

S. atropurpurea, Linn. SWEET S. Or when with dark purple or crimson
flowers, called MOURNING BRIDE ; the flowers are sometimes rose-colored
or even white ; plant l°-2° high, with obovate or spatulate and toothed
root leaves, pinnately -parted stem leaves, the cup or involucel inclosing
the ovary 8-grooved, calyx proper with 5 long bristles surmounting the
akene : outer corollas enlarged. 0

LXI COMPOSITE, COMPOSITE FAMILY.

Herbs, or a very few shrubs, known at once by the " com-
pound flower," as it was termed by the older botanists, this
consisting of several or many flowers in a head, surrounded
by a set of bracts (formerly likened to a calyx) forming an
involucre, the stamens as many as the lobes of the corolla
(almost always 5) and inserted on its tube, their anthers
syngenesious, i.e. united in a ring or tube through which the
style passes. (Lessons, Figs. 290, 291.) Calyx with its tube
incorporated with the surface of the ovary, its limb or border
(named the pappus) consisting of bristles, either rigid or
downy, or of teeth, awns, scales, etc., or of a cup or crown, or
often none at all. (Lessons, Figs. 379-384.) Corollas either
tubular or funnel-form and lobed, or strap-shaped (ligulate),
or sometimes both sorts in the same head, when the outermost
or marginal row has the strap-shaped corollas, forming rays
(which answered to the corolla of the supposed compound
flower), the separate flowers therefore called ray flowers; those
of the rest of the head, or disk, called disk flowers. The
dilated end of the stalk or branch upon which the flowers are
borne is called the receptacle. The bracts, if there are any,
on the receptacle (one behind each flower) are called the chaff
of the receptacle. The bracts or leaves of the involucre out-
side the flowers are commonly called scales. Style 2-cleft at
the apex. Ovary 1-celled, containing a single ovule, erect from
its base, in fruit becoming an akene. Seed rilled by the embryo
alone. (For the flowers, and the particular terms used in
describing them, see Lessons, pp. 93, 94, Figs. 266-269 ; for the
fruit, see p. 121, Figs. 379-384.)

The largest family of Flowering Plants, generally too diffi-
cult for the beginner; but most of the common kinds, both
wild and cultivated, are here briefly sketched. For fuller
details as to the wild ones, with all the species, the student
will consult the Manual, and Chapman's Southern Flora. The
following synopsis is arranged to aid the beginner, but the
genera are numbered in systematic sequence.

LXIV. ERICACEAE, HEATH FAMILY.

A very large family, of shrubs, herbs, or even small trees,
difficult to define as a whole ; the leaves are simple and mostly
alternate (sometimes reduced to white or colored scales) ; the
flowers almost all regular, and with as many or twice as many
stamens as there are petals or lobes of the corolla ; their
anthers 2-celled, each cell more commonly opening by a pore
or hole at the end ; ovary mostly with as many cells as there
are lobes to the corolla ; style only one, and seeds small. The
HEATH and HEATHER (the former cult, in some greenhouses
in several species, and the latter sparingly wild E.) belong to
this family, and are distinguished by small or needle-like ever-
green leaves, the corolla becoming dry and persisting, its lobes,
and those of the calyx, 4 ; stamens 8.

I. WHORTLEBEBKY SUBFAMILY, known by having
the tube of the calyx adherent to the ovary, on which the
monopetalous corolla and the stamens are therefore mounted.
All are shrubs, with scaly buds. Fruit a berry or berry-like.

1. GAYLUSSACIA. Stamens 10 ; anthers with the cells opening by a chink at the blunt

or tapering top. Ovary 10-celled with one ovule in each cell, forming a berry-like
fruit containing 10 apparent seeds, or properly little stones. Flowers in lateral ra-
cemes ; branchlets and leave.s beset with resinous or clammy dots.

2. VACCIN1UM. Stamens 10 or 8 ; anthers tapering up into a tube with a hole at the

top. Ovary with several or many ovules in each cell, forming a pulpy many-seeded
(rarely rather few-seeded) berry.

HEATH FAMILY. 263

3. CHIOGENES. Stamens 8 ; anthers with short cells minutely 2-pointed, and opening

by a large chink down to the middle. Ovary 4-celled, in fruit a white many-seeded

5-lobed or cleft ; anthers short, without aicns or other appendages, opening only
by holes at the top ; filaments long and slender, as is also the style ; pod septi-
cidal; leaves entire.

= No scaly buds; bracts green, firm and persistent.

11. KALMIA. Corolla broadly open, slightly 5-lobed, and with 10 pouches in which the

nected with the stigma, their pollen collected into firm waxy
or granular masses (mostly 10), the short filaments (monad el-
phous except in the last genus) commonly bearing curious
appendages behind the anthers, forming what is called a crown,
and the corolla more commonly valvate in the bud. The flowers
are rather too difficult for the beginner readily to understand
throughout. For a particular study of them the Manual must
.be used.

§ 1. Erect herbs, with ordinary foliage, and deeply 5-parted calyx and corolla. Flowers

a ring or tube, bearing behind each anther a curious erect and hood-like or ear-like
appendage, with a horn projecting out of the inside of it ; the 5 broad anthers closely
surrounding and partly adhering to the very thick stigma, a membranous appendage
at their tip inflected over it. Each of the 2 cells of the anther has a firm waxy pear-
shaped pollen mass in it; and the two adjacent masses from two contiguous anthers
are suspended by a stalk from a dark gland ; these 5 glands, borne o^ the margin of
the flat top of the stigma, stick to the legs of insects, and are carried off, each gland
taking with it 2 pollen masses, the whole somewhat resembling a pair of saddle bags.
Leaves mostly opposite.

LXXVIIL BORRAGINACE^E, BORAGE FAMILY.

Mostly rough or rough.-h.airy plants, known from all related
monopetalous orders by having a deeply 4-lobed ovary, or
apparently 4 ovaries around the base of a common style, each
1-ovuled, ripening into akenes or nutlets, along with regular
flowers (Echium excepted), stamens as many as the lobes of
the corolla (5) and alternate with them, and alternate (mostly
entire) leaves. In the Heliotrope tribe, however, the ovary is
not lobed, but the fruit at maturity separates into 2 or 4
nutlets. Stigmas 1 or 2. Embryo filling the seed ; no albu-
men. Mowers disposed to be on one side of the stem or
branches, or of the branches of cymes, the raceme-like clusters
coiled at the end and straightening as the flowers expand.
Herbage not aromatic ; juice commonly bitterish, often some-
what mucilaginous. Koots of several are red and used for dye.

about the length of the rounded lobes ; throat closed by the blunt scales. Nutlets
bur-like, oblique on the expanded base of the style, to which they are fixed by their
apex, roughened all over with short barbed or hooked prickles. Coarse and strong-
scented plants, with racemed flowers, the lower sometimes bracted, otherwise
bractless.

LXXXIX. LABIATE, MINT FAMILY.

Chiefly herbs, with aromatic herbage, square steins, opposite
simple leaves, more or less 2-lipped corolla (whence the name
of the order), either 4 didynamous or only 2 stamens inserted
on the corolla tube, 2-lobed stigma, and at once distinguished
from all the related families by the deeply 4-parted ovary (as
if 4 ovaries around the base of a common style), ripening into
as many seed-like nutlets (never prickly) or akenes, each con-
taining a single seed. Embryo usually rilling the seed. As
in all these families containing bilabiate plants, there are 2
lobes belonging to the upper and 3 to the lower lip of the
corolla. Flowers from the axils of the leaves or bracts, usually
in cymose clusters, or running into terminal racemes or spikes.
The peculiar stamens of this family are shown in Lessons,
Figs. 300-305.

of the corolla. Nutlets reticulated and pitted, obliquely fixed by the inner side
near the base.

III. APETALOUS DIVISION.

Includes the families with flowers destitute of corolla,
or of both corolla and calyx. Various apetalous genera
and species are, however, distributed through the poly-
pe talo us and monopetalous families, where they evidently
belong. These three divisions are entirely artificial.

XCL NYCTAGINACEJJ, FO UK-O'CLOCK FAMILY.

Here represented by a few herbs with tubular or funnel-
form calyx colored like a corolla, and falling away from a per-
sistent lower portion which closes completely over the 1-celled
1-ovuled ovary and seed-like fruit; forming a hard and dry
covering which would be mistaken for a true pericarp. Sta-
mens 2-5, the long slender filaments hypogynous, but apt to
adhere somewhat to the sides of the calyx tube above. Embryo
coiled around some mealy albumen. (Lessons, Figs. 52-55.)

Stamens 5 and style included.

* * Involucral bracts united at the base.

2. OXYBAPHUS. Flowers small, a few together surrounded by a 5-lobed involucre,

which enlarges and becomes thin, membranaceous, reticulated, and wheel-shaped

ing into a bell-shaped 5-lobed corolla-like border, open only for a day. Stamens
(mostly 3) and slender style protruding. Fruit (persistent base of calyx) akene-like,
strongly ribbed.

3. MIKABILIS. Flower large, in the common species only a single one in the cup-shaped

5-cleft green involucre, which thus exactly imitates a calyx, as the tubular funnel-
shaped or almost salver-shaped delicate calyx does a corolla. 5 stamens, and especially
the style (tipped with a shield-shaped stigma) protruded. Fruit ovoid, smooth and
nearly even.

XCIII. AMARANTACEjE, AMARANTH FAMILY.

Weeds and some ornamental plants, chiefly herbs, essentially
like the next family, but the flowers provided with dry and
mostly scarious crowded persistent bracts, and the fruit some-
times several-seeded. The filaments are often united into a
tube or cup. The cultivated sorts are ornamental, like Im-
mortelles, on account of their colored dry bracts which do not
wither.

* Flowers, both staminate and pistillate, really destitute both of calyx and corolla ; a
pistillate and numerous staminate ones surrounded by a cup-like involucre
which imitates a calyx, so that the whole may be taken for one perfect flower.

1. EUPHORBIA. These plants may be known, mostly, by having the 3-lobed ovary

raised out of the cup, on a curved stalk, its 3 short styles each 2-cleft, making 6
stigmas. Fruit when ripe bursting into the 3 carpels, and each splitting into 2 valves,
discharging the seed. What seems to be a stamen with a jointed filament is really
a staminate flower, in the axil of a slender bract, consisting of a single stamen on a
pedicel, the joint being the junction.

+- +- flowers of both kinds provided with a distinct calyx.

•*•+ Stamens 5 or more.
= Flowers in cymose (2^5-forked) panicles ; stamens 10 or more.

2. JATROPHA. Fertile flowers in the main forks of the panicle. Calyx colored like a

corolla, in the sterile flowers mostly salver-shaped and 5-lobed, enclosing 10-30 sta-
mens, somewhat monadelphous in two or more ranks ; in the fertile 5-parted. Styles
8, united below, once or twice forked at the apex. Pod 3-celled, 3-seeded. Leaves
alternate, long-petioled, with stipules.

«= = flowers in terminal racemes or spikes.

I Leaves scarcely or not at all lobed, often entire.

o Ovary and fruit 1 -celled.

8. CEOTONOPSIS. Flowers monoecious, in very small terminal or lateral spikes or clus-
ters, the lower ones fertile. Sterile flowers with an equally 5-parted calyx, 5 spatu-
late petals, and 5 stamens opposite the petals. Fertile flowers with unequally
3-6-parted calyx, 0 petals, but 5 petal-like scales opposite the divisions of the calyx.

o o Ovary 2-4 (commonly 3-) celled, or rarely ^-celled in No. 6.

4. CROTON. Flowers monoecious or dkecious, generally in racemes or spikes. Sterile

flowers with a normally 5-parted calyx, as many petals or rudiments as there are calyx
lobes and alternating with lobes of the disk, the stamens 5 or more. Fertile flowers
with a 5-10-cleft or parted calyx, the petals 0 or very small rudiments.

5. CODI^EUM. Flowers monoecious. Sterile flowers with a membrana'ceous 3-6-parted

calyx, the divisions imbricated and becoming reflexed, five short scale-like petals
alternating with as many glands, and many or numerous stamens. Fertile flowers
with a 5-cleft calyx but no petals, the ovary surrounded by 5 scales.

6. ACALYPHA. Flowers in small clusters disposed in spikes, staminate above, fertile at

base ; or sometimes the two sorts in separate spikes. Calyx of sterile flowers, 4-
parted, of fertile 3-5-parted. Stamens 8-16, short, monadelphous at base ; the 2 cells
of the anther long and hanging. Styles 8, cut-fringed on the upper face, red. Pod
of 3 (rarely 2 or 1) lobes or cells. Fertile flower clusters embraced by a leaf-like cut-
lobed bract. Leaves alternate, petioled, with stipules, serrate.

•H- -H- Stamens 2 or 3.

8. TRAGIA. Flowers monoecious and apetalous, in racemes. Sterile flowers with 3-5-

cleft calyx. Fertile flowers with 8-8-parted persistent calyx. Calyx lobes valvate i»
the bud. Plants pubescent or hairy.

CV, URTICACE.fi, NETTLE FAMILY.

This family, taken in the largest sense, includes very various
apetalous plants, with monoecious or dioecious flowers (except
in the Elm Subfamily), having a distinct calyx free from the
1-seeded (but sometimes 2-celled) fruit. Stamens as many as
the lobes of the calyx and opposite them, or sometimes fewer.
Inner bark generally tough. Leaves with stipules, which are
sometimes early deciduous.

I. ELM SUBFAMILY. Trees, the juice not milky. Leaves
alternate, 2-ranked, simple ; stipules small and falling early.

NETTLE FAMILY,. 385

Flowers monoeciously polygamous, or perfect, with the fila-
ments not iuflexed in the bud, and 2 diverging styles or long
stigmas. Ovary 1-2-celled, with 1 or 2 hanging ovules, in
fruit always 1-celled and 1-seeded.

* Fruit dry, winged or nut-like. Anthers turned outwards.

1. ULMUS. Calyx bell-shaped, 4-9-cleft. Stamens 4-9 ; filaments long and slender.

on a slender peduncle.

II. HEMP SUBFAMILY. Bough herbs, with watery
juice and tough fibrous bark. Leaves mostly opposite and
palmately lobed or compound. Flowers dioecious, greenish ;
the sterile in axillary loose compound racemes or panicles, the
fertile in close clusters or catkins ; calyx of the former with
5 sepals, of the latter 1 scale-like sepal embracing the ovary
and akene. Stigmas or hairy styles 2, long.

with milky or colored acrid or poisonous juice. Leaves alter-
nate. Flowers strictly monoecious or dioecious. Styles or
stigmas commonly 2.

* Flowers of both kinds mixed, lining the inside of a closed fleshy receptacle, or hollow

flower stalk, which ripens into what seems to be a sort of berry.

6. FICUS. Receptacle in which the flowers are concealed borne in the axil of the leaves.

Akene seed-like. Stipules large, successively enveloping the young leaves in the
bud, falling off as the leaves expand. (Lessons, Figs. 405, 406, 407.)

* * Flowers of the two kinds mostly separate; the fertile crowded in catkin-like spikes

or heads, which become fleshy in fruit ; filaments inflexed in the bud, spreading
elastically when the calyx expands.

7. MACLURA. Flowers dioecious ; the sterile in racemes, and nearly like those of Mul-

berry; the fertile densely crowded in a large spherical head, its calyx of 4 unequal
sepals, in fruit inclosing the small akene ; the whole head ripening into a fleshy
yellow mass, resembling an orange with a roughish surface.

402 FBOGBIT FAMILY.

SUBCLASS II. MONOCOTYLEDONS (or ENDOGENS).

Distinguished by having the woody matter of the stem in
distinct bundles scattered without obvious order through-
out its whole breadth, never so arranged as all to come m
a circle; when abundant enough to form proper wood, as
in Palms and the like, this is hardest and the bundles most
crowded toward the circumference. Embryo with a sin-
gle cotyledon; the first leaves in germination alternate.
Leaves mostly, but not always, parallel-veined. Parts of
the flower almost always in threes, never in fives. See
Lessons, p. 138, and for style of vegetation, p. 26, Fig. 71.

The plants of this class may be arranged under three
generally well-marked divisions.

I. PETALOIDEOTJS DIVISION.

Flowers with a perianth (calyx and corolla) which is
usually (except in Rush-like plants) colored, not on a

CXI. HYDROCHARIDACEjE, FBOG3IT FAMILY.

Water plants, with dioecious, monoecious, or polygamous
flowers on scape-like peduncles from a sort of spathe of one
or two leaves, or sessile, the perianth in the fertile flowers of
6 parts united below into a tube which is coherent with the
surface of a compound ovary ; stamens 3-12, sometimes mono-
delphous ; stigmas 3 or 6. Fruit ripening under water.

* Growing under water, the fertile flowers only rising to the surface ; the sterile (not
often detected) breaking off their short stalks, and floating on the surf ace around
the pistillate flowers.

1. ELODEA. Steins leafy and branching. Fertile flowers rising from a tubular spathe ;

the perianth prolonged into an exceedingly slender stalk-like tube, 6-lobed at top,
commonly bearing 3-9 apparently good stamens ; ovary 1-celled with a few ovules on
the walls ; style coherent with the tube of the perianth ; stigmas 3, notched.

2. VALLISNEKIA. Stemless ; leaves all in tufts from creeping rootstocks. Fertile

flowers with a tubular spathe, raised to the surface of the water on an extremely long
and slender scape ; tube of the perianth not prolonged beyond the 1-celled ovary, with
8 obovate outer lobes (sepals) and 3 small inner linear ones (petals), and no stamens.
Ovules very numerous, lining the walls. Stigmas 3, sessile, 2-lobed. Fruit cylindrical,
berry-like.

ORCHIS FAMILY. 403

* * Floating, spreading by proliferous shoots;- leaves long petioled, rounded heart-
shaped.

8. LIMNOBIUM. Flowers monoecious or diu'cious, from sessile or short-stalked leaf-like
spathes, the sterile spathe of one leaf surrounding 3 long-pediceled staminate flowers ;
the fertile 2-leaved, with one short-pediceled flower. Perianth of 3 outer oval lobes
(calyx) and 8 narrow inner ones (petals). A cluster of 6-12 unequal monadelphous
stamens in the sterile flower ; some awl-shaped rudiments of stamens and a 6-9-celled
ovary in the fertile flower; stigmas 6-9, each 2-parted. Fruit berry-like, many-
seeded.

1. ELODEA (or ANACHARIS), WATER WEED. (Greek: marshy?)
Flowers summer. 2/

E. Canadensis, Michx. Slow streams and ponds ; a rather homely
weed, with long branching stems, beset with pairs or whorls of pellucid
and veinless, 1-neryed, minutely serrulate, sessile leaves ($'-!' long),
varying from linear to ovate-oblong, the thread-like tube of the yellowish
perianth often several inches long.

2. VALLISNERIA, TAPE GRASS, EELGRASS of fresh water.
(Named for A. Vallisneri, an early Italian botanist.) Flowers late
summer. 11

V. spiralis, Linn. In clear ponds and slow streams, with bright green
and grass-like linear leaves (l°-2° long), delicately nerved and netted;
fertile scapes rising 2°-4° long, according to the depth of the water, after-
wards coiling up spirally and drawing the fruit under water to ripen.
The leaves of this and the preceding are excellent to show cyclosis.

3. LIMNOBIUM, FROGBIT. (Greek: living in pools.} Flowers
whitish, the fertile ones larger, in summer. 2/

L. Sp6ngia, Richard. Floating free on still water, N. J., W. and S. ;
rooting copiously ; leaves l'-2' long, purple beneath, tumid at base, with
spongy air cells.

CXII. OKCHIDACEJE, ORCHIS FAMILY.

Herbs, with perfect flowers of peculiar structure, the perianth
adherent to the 1-celled ovary (which has numberless minute
ovules on 3 parietal placentae), its chiefly corolla-like 6 parts
irregular, 3 in an outer set answering to sepals, 3 within and
alternate with these answering to petals, one of these, generally
larger and always different from the others, called the labellum
or lip ; the 1 or 2 stamens are gynandrous, being borne on or
connected with the style or stigma (Lessons, Fig. 284) ; the
pollen is mostly coherent in masses of peculiar appearance,
celled pollinia (Lessons, Figs. 320, 321, 322). All perennials,
and all depend more or less upon insects for fertilization.
Beginners will not very easily comprehend the remarkable
structure of most Orchideous flowers. There are numerous

species and hybrids in cultivation in choice greenhouses, but
only the commonest or most conspicuous wild species are
mentioned here.

choicest conservatories. We have one genus in the most Southern States.

1. EPLDENDRUM. The 8 sepals and 2 petals nearly alike and widely spreading ; the odd

petal or lip larger and 3-lobed, its base united with the style, which bears a lid-like
anther, containing 4-stalked pollen masses, over the glutinous stigma.

* * TERRESTRIAL ORCHIDS, growing in the soil, in woods or low grounds, but sometimes

leafless and parasitic on roots.

+- Anther only one, but of 2 cells, ivhich when separated (as in Orchis) must not be mis-
taken for two anthers ; pollen collected into one or more masses in each cell ;
stigma a glutinous surface.

leafless scape ; pollen masses 4, globular, soft-waxy.
8. APLECTRUM. Flowers as in the next, but no trace of a spur or sac, larger. Scape

rising from a large solid bulb or conn, which also produces, at a different season, a

broad and many-nerved green leaf.

4. COEALLOKHIZA. Flowers with sepals and petals nearly alike; the lip broader, 2-

ridged on the face below, from its base descending a short sac or obscure spur which
adheres to the upper part of the ovary. Scape with sheaths in place of leaves ; the
root or rootstock thickish, much branched and coral-like.
«= = Flowers rather large; pollen masses soft, of lightly -connected poiodery grains.

5. ARETHUSA. Flower only one, on a naked scape ; the 3 sepals and 2 petals lanceolate

and nearly alike, all united at the base, ascending and arching over the top of the
long and somewhat wing-margined style, on the petal-like top of which rests the
helmet-shaped hinged anther, over a little shelf, the lower face of which is the stigma.
Lip broad, erect, with a recurving rounded apex and a bearded crest down the face.
Pollen masses 4, 2 in each cell of the anther.

6. CALOPOGON. Flowers 2, 3, or several, in a raceme-like loose spike; the lip turned

towards the axis, diverging widely from the slender (above wing-margined) style,

8. SPIRANTHES. Flowers oblique on the ovary, all the parts of the perianth erect or

conniving, the lower part of the lip involute around the style and with a callosity on
each side of the base, its narrower tip somewhat recurved and crisped. Pollen masses
2 (one to each cell), each 2-parted into a thin plate (composed of grains lightly united
by delicate threads), their summits united to the back of a narrow boat-shaped sticky
gland set in the beaked tip over the stigma. Leaves not variegated.

each cell all connected by elastic threads with a central axis or stalk ; the loivef
end of which is a sticky gland or disk, by adhesion to which the whole mass of
pollen is dragged from the opening anther and carried off by insects.

10. OKCHIS. The 3 sepals and 2 petals are conniving and arched on the upper side of the

flower; the lip turned downwards (i.e. as the flower stands on its twisted ovary).
Anther erect, its two cells parallel and contiguous ; the 2 glands side by side just
over the concave stigma, and inclosed in a sort of pouch or pocket opening at the
top.

11. HABENARIA. Flower generally as in Orchis, but the lateral sepals commonly spread-

ing; the glands attached to the pollen masses naked and exposed.

•*- -i- Anthers 2 (Lessons, Fig. 284), borne one on each side of the style, and a trowel-
shaped body on the tipper side answers to the third stamen, the one that alone is
present in other Orchids; pollen powdery or pulpy; stigma roughish, not
glutinous.

12. CYP1IIPED1UM. Sepals in appearance generally only 2, and petals 2, besides the lip

which is a large inflated sac, into the mouth of which the style, bearing the stamens
and terminated by the broad terminal stigma, is declined. Pollen sticky on the sur-
face, as if with a delicate coat of varnish, powdery or at length pulpy underneath.

1. EPIDENDRUM. (Name in Greek means upon a tree, i.e. an epi-
phyte.)

E. condpseum, Ait. S. Car., S. and W., on the boughs of Magnolia,
etc., clinging to the bark by its matted roots, its tuberous rootstocks
bearing thick and firm lanceolate leaves (!'— 3' long), and scapes 2'-6'

destitute of spur. )

A. hyemale, Nutt. Woods, in rich mold, N. Eng. to Minn., and S.
in the mountains ; scape and dingy flowers in early summer ; the large
oval and plaited-nerved petioled leaf appears towards autumn and lasts
over winter ; solid bulbs one each year, connected by a slender stalk,
those of at least two years found together (whence one of the popular
names), 1' thick, filled with strong glutinous matter, which has been used
for cement, whence the other name.

4. CORALLORHIZA, CORAL ROOT (which the name means in
Greek). No green herbage ; plants probably parasitic on roots.

grass-like leaf, and at the summit 2-6 beautiful pink-purple flowers (!'
broad), the lip as if hinged at its base, bearded with white, yellow, and
purple club-shaped hairs. Bogs, N. ; one of the common orchids.

Orchises, viz.,

O. spectdbilis, Linn. SHOWY ORCHIS. Plant with 2 oblong-obovate,
thick, glossy leaves (3'-5' long) from the fleshy-fibrous root, and a leafy -
bracted scape 4'-7' high, bearing in a loose spike a few pretty flowers,

11. HABENARIA, REIN ORCHIS. (Latin habena, a rein or thong,
from the shape of the lip of the corolla in some species.) Flowers in
a terminal spike, each in the axil of a bract, in late spring and summer.
In all but one species the ovary twists and the lip occupies the lower
or anterior side of the flower. (Lessons, Figs. 320-322.) The follow-

(Greek name for Venus, joined to that for a slipper or buskin.) Among
the most ornamental and curious of our wild flowers, blooming in
spring and early summer. Rootstocks very short and knotty, produc-
ing long and coarse fibrous roots. Many tropical species and hybrids
are in cultivation. (Lessons, Fig. 284.)

C. arietinum, R.Br. RAM'S-HEAD L. The smallest species, with
slender stem 6'-10' high, oblong lanceolate leaves, and a dingy, purplish,
drooping flower, the sac conical and in some positions resembling a ram's
head, one sepal lance-ovate, the two others and the two petals linear.

long, wliite flowers with the globular lip (!£' long) painted with pink-
purple, in July. One of the handsomest and most interesting of all wild
flowers.

H- •*- Scape naked, bearing a small bract and one flower at summit.

C. acatile, Ait. STEMLESS L. Moist or sandy ground N., mostly in
the shade of evergreens ; scape 8'-12' high ; sepals and petals greenish or

oblong-obovate, drooping sac, which is split down the front but nearly
closed ; flowers in spring.

CXni, SCITAMLNEJE, BANANA FAMILY.

A group of tropical or subtropical perennial plants, with
leaves having distinct petiole and blade, the latter traversed
by nerves running from the midrib to the margin; flowers
irregular, with a perianth of at least two ranks of divisions,
below all combined into a tube which is adherent to the 3-celled
ovary ; the stamens 1-6 and distinct. We have two wild
representatives on our southeastern borders ; the many culti-
vated ones are chiefly grown for their ornamental foliage, and
some of them are rarely seen in blossom. They are therefore
seldom available for botanical study.

I. GINGER SUBFAMILY. Seeds, rootstocks, or roots
hot-aromatic. Stamen 1, with a 2-celled anther, commonly
embracing the style, but not united with it; staininodia some-
times present. GINGER is the dried rhizomes of ZINGIBER
OFFICINALE of the tropics.

1. HEDYCHIUM. Flowers with a slender tube bearing- 6 divisions which may be likened
to those of an Orchideous flower, one (answering to the lip) much larger and broader
than the 5 others, and a very long, protruding, reddish filament terminated by a yellow
unappendaged anther sheathing the style up almost to the stigma.

II. ARROWROOT or INDIAN SHOT SUBFAMILY.

No hot-aromatic properties, the thick rootstocks, etc., com-
monly containing much starch, from which genuine arrowroot
is produced. Stamen 1, with a 1-celled anther. ARROWROOT
is the product of species of MARANTA.

BANANA FAMILY. 411

* Capsule \-celled and \-seeded.

2. THALIA. Stemless herbs, with an elongated scape and radical long-stalked leaves.

qual (the anterior division broad and hooded, one elongated and clawed and one partly
adnate to the stamen and furnished with two bristles on one side). Stigma 2-lipped.
* * Ovary 3-celled (rarely 2-celled), the cells \-ovuled.

3. CALATHEA. Strong-growing ornamental-leaved plants with flowers in imbricated

bracteate heads or cone-like spikes or rarely in somewhat lax spikes. Outer 3 seg-
ments of perianth lanceolate, the 3 inner ones irregular and obtuse. Corolla tube often
slender. Staminodia present and petal-like.

* * * Capsule o-celled, the cells several-** -seeded.

4. CANNA. Mostly tall plants with showy flowers in an erect spike or raceme terminating

the stem. Stamen a petal-like filament with the anther upon one side.

III. BANANA SUBFAMILY PROPER. Not aromatic or
pungent. Stamens 5 with 2-celled anthers, and an abortive
naked filament.

5. MUSA. Strong somewhat palm-like plants with flowers In long nodding bracteate

spikes or racemes. Calyx tubular and elongated, 3-5-toothed and inclosing the small
corolla. Fruit fleshy and indehiscent.

6. STEELITZIA. One cultivated species, wHh the scape bearing at apex an oblique or

horizontal and rigid conduplicate spathe, from which several large and strange-looking
blossoms appear in succession ; the 3 outer divisions of the perianth 3'-4' long, orange-
yellow, one of them conduplicate and taper-pointed, and somewhat like the two larger
of the bright blue inner set, or true petals, which are united and cover the stamens,
the other petal inconspicuous.

late or oblong, clasping, 2-ranked; flowers light yellow, fragrant, in a
large terminal spike. India.

H. coronarium, Kcern. Plant 2°-5°, with 2-ranked, oblong, sessile
leaves, and large, snow-white, sweet flowers, the lip nearly 2' wide.

3. CALATHEA. (Greek : a basket, alluding either to the basket-
shaped stigma or to the use of the leaves in basket-making in S. Amer.)
The plants are generally known as MARANTAS. Natives of trop. Amer.
Following are the commonest in greenhouses.

* Leaves marked only by transverse bars.

C. ze6r?.*?a, Lindl. The oblong leaves 2 or 3 feet long, purple beneath,
the uppp.r surface satiny and with alternating stripes of deep and pale
green : flowers dull purple, inconspicuous, in a bracted head or spike

with a feathery stripe of yellow-green running from base to apex upon
either side of the midrib.

4. CANNA, INDIAN SHOT. (Name obscure.) The 3 small green
leaves which remain on the capsule are the sepals. The showy parts
of the flower, inside the petals, are the petal-like staminodia, the upper
two or three of which are very prominent. Tropical (mostly American)
plants, now much used in lawn decorations. The cultivated forms,
which are much confused, are chiefly from the following :

* Corolla lobes and staminodia united into a short tube, the two or three

upper staminodia being developed.

-*- Upper staminodia 3.

C. /ndica, Linn. INDIAN SHOT. First species introduced ; stem slender,
glabrous and green, 3°-5° high ; leaves oblong, acute, green, lower ones
a foot long ; flowers in a loose, simple raceme, with suborbicular green
bracts; sepals green; petals pale green, lanceolate, 1^' or less long;
staminodia bright red, lip reddish-yellow, spotted with red. The Cannas
known as C. LIMBA.TA or AtiRKo-viTT\TA (the upper staminodia red bor-
dered with yellow), and C. coccfNEA (with red-tinged sepals and petals,
and often bordered staminodia) are evidently forms of this species.

2' long, lanceolate, red-tinged ; staminodia oblanceolate, bright red,
large, the lip plain red and notched at the apex.

C. glatica. Linn. Stem 5°-6°, green and glaucous, as are the leaves ;
the latter oblong-lanceolate and very acute, the lower ones 1.]° long;
racemes lax, either simple or forked ; sepals lanceolate, small, green ;
petals 2' or less long, lanceolate, yellowish-green; staminodia clear pale
yellow, 3' or less long, the lip linear and notched, pale yellow. C. ANNASI
is an offshoot or hybrid of this, and was the parent of many of the older
tall Cannas.

-»- +- Upper staminodia usually 2.

C. ftitea, Miller. (Comprising C. PALLIDA with the upper staminodia
pale yellow and red-spotted ; and C. ATIRANTIACA with red-tinged petals,

and distinctly notched.

C. speciosa, Roscoe. Stem 5°-6° high, green and glabrous ; leaves green,
broad-oblong and acute, the lowermost often 2° long ; panicle deeply
forked ; sepals lanceolate and pale red ; petals 2' long, lanceolate, pale
red ; staminodia notched, bright red, 3' long, the lip also notched at the
apex, and bright reddish-yellow. Himalayas.

C. discolor, Lindl. Stem 5°-10° high, glabrous and glaucous, purple;
leaves broad, oblong and acute, claret-brown, the lowermost sometimes
3° long ; panicle deeply forked, the bracts orbicular ; sepals small, lance-
olate and green ; petals lanceolate, pale green ; staminodia oblanceolate
and entire, bright red, 22° long ; lip lanceolate and notched, brick-red.

* * Corolla tube 2' or more long; upper staminodia 3, clawed; lip

orbicular.

C. fldccida, Salisb. Wild in swamps, S. Car., S.; 2°-4° high, with
ovate-lanceolate, pointed leaves, and yellow flowers 3'-4' long; all the
inner divisions obovate and wavy, lax, the 3 corolla lobes reflexed.

slightly pubescent beneath, bright green ; panicle composed of several
drooping racemes ; sepals 1'long, lanceolate, green ; corolla lobes lance-
olate, red-brown ; staminodia 3, somewhat longer than the corolla lobes,

C. EHEMANNI of gardens is a hybrid of this and probably C. Warsce-
wiczii. The modern race of dwarf and Crozy "flowering" Cannas is
mostly sprung from this garden form again crossed, the red-flowered ones
being mainly hybrids of C. Ehemanni and C. Warscewiczii, and the yel-
low-flowered ones largely of C. Ehemanni and C. glauca.

C. liliifldra, Warsc. Similar to C. iridiflora in habit, but the flowers
white and fragrant. Not yet common, but it will undoubtedly play an
important part in garden forms in the future.

5. MUSA, BANANA, PLANTAIN. (Antonius Musa, physician to
Augustus.)

13. SPARAXIS. (Greek: to tear, referring to the torn spathes.)
Cape of Good Hope.

S. grand/flora, Ker. (S. FIMBRI\TA, S. LACERA, S. LILIAGO, S. ATRO-
puRrtjREA, and others.) Stem terete and erect, 6'-2° high, simple or
branched, with a few linear or lanceolate leaves near the base ; flowers
yellow or purple (but variable in cultivation) , the segments 1' or more long.

5. tricolor, Ker. (S. vERsfcoLOH, S. LINEATA, and others.) Differs
from the last in always having a bright yellow throat and a dark blotch
at the base of each segment.

14. GLADIOLUS, CORN FLAG. (Name a diminutive of the Latin
word for sword, from the leaves.) A genus of about 130 species, many
of which are in cultivation. The commonest garden forms are hybrids,
derived from the following, in which the perianth tube is funnel-shaped,
and the segments are not distinctly narrowed into claws.

* Leaves subterete or linear.

two long ; stem slender and terete, l°-2° high ; flowers 3-4, yellowish-
white, in a loose secund spike, fragrant ; flower 2'-3' long, the tube curved
and longer than the oblong and acute falcate segments. Cape of Good
Hope. G. COXCOLOR is a form with paler flowers, noted as being one of
the parents of the garden race, G. CoLvfLLEi (see G. cardinalis).

G. cuspidatus, Jacq. Leaves 3-4, flax but linear ; stems l°-2° high ;
flowers white or pale pink with a spade-shaped blotch in the center of the
3 outer segments, 4-8 in a very lax, nearly or quite equilateral spike ;

Cape of Good Hope. Parent, with G. cardinalis, of the hybrid class G.
GANDAVENSIS, to which belong most of the older bright-flowered and late
varieties. The upper segment, in these varieties, is usually horizontal

One parent (with G. tristis) of G. CoLvfLLEi, a race with bright scarlet
nearly erect flowers and oblong acute segments, the lower 3 having a long-
blotch of yellow at the base. A white-flowered form of this race is in
cultivation (known as the BRIDE). G. cardinalis is also one parent of
G. Gandavensis, G. ramosus, and G. pudibundus (see above).

G. Saundersii, Hook. f. Leaves 4-6, rigid and strongly ribbed ; stem
l|°-2° high; spike very lax and 6-8-flowered ; flower bright scarlet, with

456 BUSH FAMILY.

Four small families, mostly of rush-like plants, are some-
what related to the foregoing, but they are unattractive to the
beginner and are rather too recondite for description here.
For their study, the Manual should be consulted. These are

CXXIII. XYEIDACE^], YELLOW-EYED GKASS F.

Small, rush-like herbs, with equitant leaves, like Bulrushes
in having flowers in a head or spike, one under each firm
glume-like bract, but with a regular perianth of 3 sepals and
3 colored (yellow) petals ; also a 1-celled many-seeded ovary
and pod with 3 parietal placentae, and a 3-cleft stigma. Over
a dozen species of XYRIS in our territory, mostly in boggy
places or pine barrens.

CXXIV. MAYACKE, MAYACA FAMILY.

Moss-like aquatic plants, densely clothed with narrow-linear,
sessile, and pellucid leaves, and bearing axillary, naked, 1-
flowered peduncles, the perfect white flower 3-androus. One
species, MAYACA MICHAUXII, in shallow water, Va., S.

CXXV. ERIOCAULONACE^l, PIPEWOET FAMILY.

Another small group of marsh or aquatic herbs, of rush-like
appearance, with a head of monoecious, white-bearded flowers,
in structure somewhat like the Yellow-eyed Grass, terminat-
ing a naked scape, at the base of which is a tuft of grassy awl-
shaped, linear, or. lanceolate leaves of loose cellular texture,
not equitant, but the upper surface concave. A half dozen spe-
cies in the genera ERIOCATJLON, P^PALANTHUS, LACHNOCAULON.

CXXVI. JUNCACE^:, BUSH FAMILY.

Plants with the appearance and herbage of Sedges and
Grasses, yet with flowers of the structure of the Lily Family,
having a complete perianth of 6 parts, 3 outer and 3 inner,
but greenish and glume-like. Stamens 6 or 3, style 1 ; stigmas 3.

1. JUNCUS. Ovary and pod 3-celled or almost 3-celled, many-seeded. Herbage smooth ;

stems often leafless, generally pithy.

2. LUZULA. Ovary and pod 1-celled, with 3 parietal placentae, and one seed to each.

Stems and leaves often soft-hairy.

The only conspicuous species is JtiNcus EFFUSUS, Linn., the COMMON
BULRUSH, in low grounds ; has soft and pliant stems in clumps, 2°-4°
high ; panicle of many greenish flowers ; 3 stamens ; and very blunt poa.

ARUM FAMILY. 457

II. SPADICEOUS DIVISION.

Flowers either naked, i.e. destitute of calyx and corolla,
or these, if present, not brightly colored, collected in the
sort of spike called a spadix, which is embraced or sub-
tended by the kind of developing bract termed a spathe.
The most familiar examples of this division are offered by
the Arum Family. There are various exceptions to this
style of inflorescence, and the division, like all others, is
merely artificial, but it will serve to aid the beginner.
The first two families are too difficult for the beginner.

CXXVII. NAIADACE^E, PONDWEED FAMILY.

Marsh or aquatic plants with steins mostly leafy and jointed,
the leaves stipulate or sheathing, the flowers (sometimes not
spathaceous) perfect or unisexual, with 4 or 6 distinct incon-
spicuous segments, or the perianth tubular, or even wanting.
Stamens 1-6. Ovaries 1-6, distinct or nearly so, 1-celled and
usually 1-ovuled, the fruit follicular or fleshy. Our genera are
TRIGLOCHIN, SCHEUCHZERIA, with bladeless leaves, allied to
the water Plantain Family, the former with naked, scape-like
stems ; and POTAMOGETON, the POISTDWEEDS, with many diffi-
cult species, RUPPIA and ZOSTERA, grass-like immersed plants
on the seacoast, ZANNICHELLIA, a similar plant in fresh water,
and NAIAS, slender and inconspicuous branchy plants, mostly
in fresh water.

CXXVIII. LEMNACE^E, DUCKWEED FAMILY.

Minute, stemless plants reduced to a floating leaf-like body
three fourths inch or less long (in LEMNA) or even to minute,
green grains (in WOLFFIA). The least of flowering plants.

CXXIX. ARACE^E, AEUM FAMILY.

Perennial herbs with pungent or acrid watery juice, leaves
often with veins reticulated so as to resemble those of Dicoty-
ledons, small perfect or imperfect flowers in a fleshy head or
spike called a spadix, usually furnished with the colored or
peculiar enveloping bract called a spathe. Floral envelopes

458 ARUM FAMILY.

4-6, or 0. Fruit generally a berry. A large family in the
tropics, and comprising many plants of choice collections, cul-
tivated for the foliage, or for the showy, so-called " flowers,"
which are really colored spathes.

* Plants with expanded leaf blade (never linear) , and with spreading nerves or veins.

+- Spadix surrounded by a conspicuous, generally colored, spathe.

-M- Leaves (in ours) compound.

1. AEIS.iEMA. Leaves only one or two, with stalks sheathing the simple stem, which

rises from a fleshy conn, and terminates in a long spadix bearing nude flowers only
at its base, where it is enveloped by the convolute lower part of the greenish or pur-
plish spathe. Sterile flowers above the fertile, each of a few sessile anthers ; the
fertile each a 1-celled 5-6-ovuled ovary, in fruit becoming a scarlet berry ; commonly
dioecious, the stamens being abortive in one plant, the pistils abortive in the other.
•H- -H- Leaves simple.

= Foliage of ordinary size, the leaves arrow-shaped or heart-shaped, or sometimes
nearly lanceolate.

H Spathe convolute (its margins overlapping below) about the spadix.

2. ARUM. Leaves hastate or sagittate, with the scape from a thick rhizome. Spathe

convolute below, large, the blade ovate or ovate-lanceolate, mostly dark-colored,
spotted or green. Spadix shorter than the spathe, sessile. Flowers without enve-
lopes, monoecious, the staminate above. Ovary oblong and obtuse, 1-celled, 6-00 -
seeded. Berry obovoid, many-seeded.

anthers each of 5 or 6 cells, opening by a hole at the top, below with 1-celled ovaries
bearing several erect ovules, in fruit a 1-3-seeded fleshy bag. Seeds obovate, sur-
rounded by a tenacious jelly.

4. EICHAKDIA. Leaves arrow-shaped ; these and the long scape from a short tuberous

rootstock. Spathe broad, spreading above, convolute at base around the slender
cylindrical spadix, which is densely covered above with yellow anthers, below with
ovaries, each incompletely 3-celled, and containing several hanging ovules. Flowers
with no envelopes.

1 II Spathe shell-form or hooded, inclosing the globular spadix, in which thefloioers are
as it were nearly immersed.

5. SYMPLOCARPUS. Leaves ovate, very large and veiny, short-petioled, appearing

much later than the flowers from a fibrous-rooted conn or short rootstock. Spathe
ovate, incurved, thick, barely raised out of the ground. Each flower has 4 hooded
. sepals, 4 stamens with 2-celled anthers turned outwards, and a 1-celled, 1-ovuled
ovary tipped with a short awl-shaped stj'le ; the fruit is the enlarged spongy spadix
under the rough surface of which are imbedded large fleshy seeds.

H 1 || Spathe open and spreading (not rolling around the spadix).

6. CALLA. Leaves heart-shaped, on long petioles ; these and the peduncles from a creep-

ing rootstock. Spathe open, the upper face bright white, spreading widely at the
base of the oblong spadix, whiph is wholly covered with the nude flowers ; the lower
ones perfect, having 6 stamens around a 1-celled ovary ; the upper often of stamens
only. Berries red, containing a few oblong seeds, surrounded with jelly.

SEDGE FAMILY. 466

III. GLUMACEOUS DIVISION.

Flowers inclosed or subtended by glumes or husk-like
bracts ; no proper calyx or corolla, except sometimes mi-
nute bristles or scales which represent the perianth. Stems
of the straw-like sort, called culms.

CXXXIH CYPERACE^l, SEDGE FAMILY.

Some rush-like, others grass-like plants, with flowers in
spikes or heads, one in the axil of each glume, the glume
being a scale-like or husk-like bract. No calyx nor corolla,
except some vestiges in the form of bristles or occasionally
scales, or a sac which imitates a perianth; the 1-celled 1-
ovuled ovary in fruit an akene. Divisions of the style 2 when
the akene is flattish or lenticular, or 3, when it is usually tri-
angular. Leaves, when present, very commonly 3-ranked, and
their sheath a closed tube; the stem not hollow. A large
family, to be studied in the Manual, and too difficult for the
beginner. The most prominent genera are the following:

* Flowers commonly all perfect.

•*- Spikelets usually many-flowered witli only one or two of the lower
scales without flowers.

•«• Scales 2-ranked, the spikelet therefore flat.
= No bristles about the akene, and no beak at its top.

1. CYFERUS. Spikelets few-many-flowered, mostly flat and slender,
in simple or compound terminal umbels or heads. Culms mostly tri-
angular and simple, most of the leaves at the base. Many species in
low grounds ; three should be mentioned here :

C. rotdnduB, Linn. NUT GRASS, Coco GRASS. A bad weed in sandy
lands from L. I., S. ; early leaves grass-like and tufted, 3'-6' high, 'followed
later in the season by a single, leafless, triangular culm, 6'-20' high ;
umbel simple or slightly compound, about equaling its involucral leaves,
its rays few, and each one bearing 4-9 dark-chestnut, 12-40-flowered,
acute spikelets ; scales nerveless. The plant is introduced in the N.
It persists in the soil by means of little, nut-like tubers which are borne
from several inches to 4° away from the base of plant, on stolons.

C. escul^ntus, Linn. CHUFA. Cultivated, especially at the S., for
its edible tubers, which are clustered about the base of the plant, and
also wild ; early leaves 15'-30' high, slightly rough, about as long as the
stem ; umbel 4-7 -rayed, sometimes compound, much shorter than the
involucral leaves ; spikelets numerous and light colored, 1 2-30-flowered,
the scales nerved. The cultivated form rarely flowers in the N.

466 SEDGE FAMILY.

C. alternifo/iuSj Linn. UMBRELLA PLANT. A greenhouse aquatic from
Madagascar ; culms in clumps, 2°-6° tall, smooth and triangular, leafless
below, but bearing a leafy, many-rayed, great involucre at the top, from
the axils of which spring slender-peduncled small clusters of flowers.

C. Papyrus, Linn. (PAPYRUS ANTIQUORUM). EGYPTIAN PAPER PLANT.
Sometimes grown in aquaria, not hardy N. ; sends up a jointless triangular
stem 4°-10° high, which is terminated by a great involucre of very narrow
drooping or bending leaves.

= = Bristles about the akene, which is beaked on top.

2. DTJLICHIUM. Spikelets 6-10-flowered, sessile in 2 ranks on axil-
lary peduncles springing from the sheaths of the leaves. Perianth com-
posed of 6-9 barbed bristles. .

One species, D. spathaceum, Pers., in bogs and on borders of ponds,
remarkable in the family for having terete and hollow culms, l°-2° high.

++ +H- Scales not '2-ranked, the spikelet therefore terete.
= Bristles 0 ; culm leafy.

3. FIMBRISTYLIS. Spikelets umbelled, the involucral leaves 2-o.
Small plants of either low or dry grounds, of about a half dozen species
in our territory.

= = Bristles generally present ; culm leafy or naked.

II /Style somewhat thickened or bulbous at the base, and persistent upon the
top of the akene.

4. ELEOCHARIS. Spike one, and without involucre, terminating a
slender, simple, leafless culm. Many species (mostly small) in moist
grounds and borders of ponds.

|| || Style not swollen at the base, deciduous.

5. SCIRPUS. Spikelets generally clustered in a compound umbel.
Bristles (sometimes 0) barbed. Mostly tall, rush-like, leafy, common
plants, but in some species the stems are slender and leafless, and the
spike is single and terminal, thus approaching Eleocharis, but the invo-
lucre is present in the form of a scale or small leaf. This genus now
includes ISOLEPIS, to which the slender species with a solitary terminal
spike, leafless and jointless culms, have been referred.

6. ERIOFHORUM. Like Scirpus, but the bristles not barbed and
often becoming silky and long exserted in fruit. A few plants in bogs,
mostly distinguished when mature by the white, or rusty, woolly heads.

H_ +. Spikelets only l-2-flowered, and 2 or many of the lower scales flower-
less.

7. RHYNCHOSFORA. Spikelets flattish, clustered, or panicled,
often whitish or rusty in color. Bristles usually surrounding the
beaked or tubercle-topped akene. A score of critical species, mostly
small and slender plants, in bogs.

8. CLADIUM. Spikelets terete. Akene not tubercled, and no bris-
tles. A single species, C. mariscoldes, Torr., l°-2° high, in wet
places, with small, rusty cymes of capitate spikelets.

GRASS FAMILY. 467

•

# * Flowers unisexual (plants monoecious or dioecious').

9. SCLERIA. Monoecious. No bristles, and the bony or crustaceous
akene naked. About a score of small plants known as NUT RUSH.

10. CAREX. Monoecious or dioecious. Ordinarily no bristles, but the
lenticular or triangular akene inclosed in a sac or perigynium. A vast
genus, comprising over 200 species in our region, much too difficult for

CXXXIV. GRAMINEJ1, GKASS FAMILY.

Grasses, known from other glumaceous plants by their 2-
ranked leaves having open sheaths, the jointed stems com-
monly, but not always hollow, and the glumes in pairs, viz. a
pair to each spikelet even when it consists of a single flower
(these called glumes proper), then a succeeding pair (flowering
glumes), rarely one of them wanting, these each inclosing a
thinner scale or palet. Flower, when perfect, as it more com-
monly is, consisting of 3 stamens (rarely 1, 2, or 6), and a
pistil, with 2 styles or a 2-cleft style, and 2 either hairy or
plumose-branched stigmas; ovary 1 -celled, 1-ovuled, becoming
a caryopsis (the thin pericarp adnate to the seed and seeming
to be an integral part of it) ; the floury part is the albumen of
the seed, outside of which lies the embryo (Lessons, Figs.
66-70).

The real structure and arrangement of the flowers and spike-
lets of Grasses are too difficult and recondite for a beginner.
For their study the Manual must be used ; in which the gen-
era both of this and the Sedge Family are illustrated by plates.
Here is offered merely a short way of reaching the names of
the commonest or most conspicuous species.

IV. LAWN AND PASTURE GRASSES. The best and the commonest lawn
grass North and East is June Grass or Kentucky Blue Grass, already
described, and it is the commonest basis of old pastures. Eedtop is
also common in lawns and pastures, but it is generally run out after a
time by June Grass. Sweet Vernal and Orchard Grass are often found
in lawns. Other common lawn and pasture Grasses are the following :

CLASS II. GYMNOSPERMS.

Plants with no closed ovary, style, or stigma, but ovules
and seeds naked on a scale or some other sort of trans-
formed leaf, or in Yew at the end of a scaly-bracted stalk ;
the mouth of the ovule receiving the pollen directly.
Leaves not netted-veined. Cotyledons often more than 2.
(Lessons, Figs. 56, 57, 337-339, 411-413.)

GXXXV. CONIFERS, PINE FAMILY.

Trees or shrubs, with wood of homogeneous fiber (no ducts),
resinous juice, commonly needle-shaped or awl-shaped leaves
(mostly evergreen), and monoscious or sometimes dioecious
flowers destitute of both calyx and corolla, and in catkins, or
the like.

Aside from the species here described, there are the follow-
ing, amongst others, in cultivation: ARAUCARIAS, particularly
A. IMBRICATA, Pav., the MONKEY PUZZLE, from Peru, with
ovate-lanceolate, pointed, stiff, keeled leaves, grown under glass,
and in the open S. ; SCIADOPITYS VERTICILLATA, Sieb. & Zucc.,
PARASOL TREE, from Japan, grown out of doors, with long,
linear, verticillate leaves ; CEPHALOTAXUS DRUPACEA, Sieb. &
Zucc. (known also as C. FORTUNI), a straggling shrub planted
from Japan in the middle and southern states with dioecious,
flat, linear, 2-rowed leaves, and a drupe-like fruit the size of a
small plum which ripens the second year.

I. PINE SUBFAMILY, PROPER. These are true Coniferce,
or cone-bearing trees, the fertile flowers being in a scaly catkin
which becomes a strobile or scaly cone. The scales are each
in the axil of a bract (which is sometimes evident and pro-
jecting, but often concealed in the full-grown cone), and bear
a pair of ovules adhering to their inner face next the base, the
orifice downwards, and the 2-winged seeds peel off the scale
as the latter expands at maturity. They all have scaly buds.
Leaves scattered or fascicled.

PINE FAMILY. 477

« Cones maturing the second year, and the scales becoming thick and corky.

1. PINUS. Leaves persistent, long and needle-shaped, 2, 3, or 5 in a cluster from the axil

of dry bud scales, developed after the scaly shoot of the season lengthens. Sterile
catkins clustered at the base of the shoot of the season ; each stamen answers to
a flower, reduced to a 2-celled anther, with hardly any filament. Cone woody, mostly
large, maturing in the autumn of the second year. Cotyledons of the embryo
several. (See Lessons, Figs. 56, 57, 184, 185, 411-413.)
« * Cones maturing the first year (except in No. 6), the scales remaining thin.

+- Leaves persistent ; i.e., evergreen.
-H- With cones pendulous or reflexed, their scales persistent.

2. PICEA. Cones terminal. Sterile flowers mostly axillary (sometimes terminal), on

branchlets of the preceding year. Leaves needle-shaped and 4-angled, sessile, scat-
tered or spirally disposed.

8. TSUGA. Cones on the ends of last year's branchlets. Sterile flowers in a sub-globose
cluster springing from the axils of last year's leaves. Leaves short, flat and whitened
beneath, short-petioled, 2-ranked.

4. PSEUDOTSUGA. Cones large, the bracts more or less exserted and spreading or

reflexed, causing the cones to appear fringed. Leaves flat, short-petioled, 2-ranked.
-H- -H- With cones erect, the scales at length deciduous.

5. ABIES. Canes on the upper side of spreading branches, the bracts mostly exserted.

Sterile flowers from the axils of last year's leaves. Leaves flat, whitened, and with
the midrib prominent beneath, sessile, scattered, but appearing 2-ranked on hori-
zontal branches.

6. CEDRUS. Leaves as in Larix, but rigid and persistent. Cones globular, large, of very

broad thin scales. +. ^ Leave8 deciduous.

1. LARIX. Leaves all falling in autumn, soft, short-needle-shaped, in spring, developed
very many in a dense cluster from axillary buds of the previous summer, those on
shoots of the season similar but scattered. Cones as in Abies, the scales persistent.
(Lessons, Figs. 184, 337.)

II. CYPRESS SUBFAMILY. These have both kinds of
flowers in short, often globular, catkins of few scales ; the fer-
tile making a globular or ovate, small cone, which is often
fleshy when young, sometimes imitating a berry. The branches
appear and the shoots grow on without the intervention of
any scaly buds. Leaves often opposite or whorled, sometimes
scale-like and adnate to the branch.

* Scales of the globular cone with a pointed bract behind each wedge-shaped scale, partly
cohering with its back.

8. CRYPTOMERIA. Cone terminating a leafy branch, the recurved tip of the bract and

awl-shaped lobes of the top of the scales projecting.

* * Scales of the fruit simple, no bract behind them.

-*- Fruit a sort of cone, dry and hard when mature ; flowers monoecious, rarely dioecious.
•H- Leaves deciduous, thin and delicate, flat.

9. TAXODIUM. Two kinds of flowers on the same branches ; the sterile catkin spike-

panicled, of few stamens ; the fertile in small clusters. Cone globular, firmly closed
till mature, of several very thick-topped and angular shield-shaped scales, a pair of
erect 8-angled seeds on their stalk.

•M--H- Leaves evergreen, linear and aid-shaped, alternate, free, destitute of glands.
10. SEQUOIA. Catkins globular, the scales of the fertile ones bearing several ovules.
Cone woody ; the shield-shaped scales closed without overlapping, and bearing 8-5
flat wing-margined seeds hanging from the upper part of their stalk -like base.

478 PINE FAMILY.

•H- -n- -n- Leaves evergreen, opposite, awl shaped and scale shaped (the former on the
more vigorous lengthening shoots, the latter closely imbricated and decussate
on the succeeding branchlets), commonly with a resinous gland on the back.
Seeds and ovules erect ; cotyledons only -i or o.

11. CUPEESSUS. Cones spherical ; the shield-shaped scales closing by their well-fitted

margins, not overlapping, separating at maturity, each scale bearing many ovules
and narrowly-winged seeds, its broad summit with a central boss or short point.

12. CHAM^ECYPAEIS. Cone globose, terminal, firmly closed, but opening at maturity,

the scales peltate. Sterile flowers composed of shield-shaped, scale-like filaments
bearing 2-4 anther cells. Leaves small and scale-like, appressed or spreading. Seeds
2-3 below each scale, in which it differs chiefly from Cnpressus.

13. THUJA. Cones oblong or globular, the scales not shield-shaped, but concave and fixed

by their base, overlapping in pairs, pointed if at all from or near their summit,
spreading open at maturity, each bearing a single pair of ovules and winged seeds.
(Lessons, Figs. 338, 339.)

-*- +- Fruit berry like; flowers commonly diwcious.

14. JTJNIPEEUS. Catkins very small, lateral ; the fertile catkin of 3-6 fleshy scales grow-

ing together, and ripening into a sort of globular berry, containing 1-3 bony seeds.
Leaves evergreen, opposite or whorled.

III. YEW SUBFAMILY. Distinguished by having the
fertile catkin, if it may be so called, reduced to a single, ter-
minal flower, consisting of an ovule only, surrounded by some
bracts or a fleshy disk, ripening into a nut-like or drupe-like
seed ; cotyledons only 2. There is nothing answering to the
scales of a pine cone. Leaf buds scaly as in the true Pine
Family. Flowers mostly dioecious, axillary.

15. TAXUS. Leaves linear, appearing more or less 2-ranked, green both sides. Both kinds

of catkins, if such they may be called, are small axillary buds imbricated with per-
sistent scales, bearing at the apex, one a few naked stamens each Avith 3-8 anther
cells under a somewhat shield-shaped apex, the other an ovate ovule. This in fruit
becomes a nut-like blackish seed, resting in the bottom of a berry-like red cup.

16. TOEEEYA. Leaves, catkins, etc., nearly as in Taxus. Stamens more scale-shaped

at top, each bearing 4 hanging anther cells. Naked seed resembling a thin-fleshed
drupe or when dry a nut, with no cup around it, as large as a nutmeg, which it
resembles also in the brain-like interior structure.

17. GINKGO. Leaves wedge-shaped and fan-shaped, deeply 2-cleft and the lobes wavy-

toothed and somewhat cleft at the broad truncate end, traversed with straight simple
or forking nerves or veins, like a Fern. Flowers not often seen. Sterile catkins
slender and loose. Seed drupe-like, and with a fleshy short cup around its base.

18. PODOCAEPUS. The fleshy seed raised on a sort of stalk. Leaves sometimes much

unlike those of other Coniferous trees, being large, linear, lanceolate, or even ovate,
and veinless, except the midrib.

1. PINUS, PINE. (The classical Latin name.) Flowers In late
spring.

* WHITE PINES, with soft leaves 5 in the cluster, their sheath and the
scale underneath early deciduous; cones long, cylindrical, terminal,

T. occidentalis, Linn. AMERICAN ARBOR VIT^E, or WHITE CEDAR

(incorrectly) of the N. and of lumbermen. Common tree N., in swamps
and cool, moist woods, much planted, especially for hedges and screens ;
leaves mostly of the scale-shaped sort, blunt, and adnate ; cones oblong,
rather soft, the oblong scales pointless, and bearing 2 thin-winged seeds.
Many nursery varieties, some of which, especially var. ERICOIDES or
HEATH-LIKE A., have the loose, awl-shaped sort of leaves. SIBERIAN
ARBOR VIT.^E is a form of it.

T. orientalis, Linn. (Bi6rA ORIENTALS). CHINESE A. Not hardy far
N. ; small tree, with even the scale-shaped leaves acute ; cone larger,
with thicker scales tipped with a recurving, horn-like apex or appendage,
each 2-seeded, and the seeds hard-shelled and wingless. Numerous forms
are cultivated.

T. dolabrata, Linn. (THUYOPSIS DOLABRA.TA). Japan. Remarkable for
its very flat spray, broad and very blunt, large leaves (sometimes \' long)
green above and white beneath ; the cone with thick and rounded scales,
each with 5 wing- margined seeds.

14. JUNIPERUS, JUNIPER. (Classical Latin name.) Flowers late
spring.

* Leaves like those of Cypress and Arbor Vitce (both scale-like and awl-

shaped, small, the former sort minute and very adnate).

J. Virginiana, Linn. RED CEDAR, SAVIN. A familiar shrub and
small or large tree, with most durable and valuable, reddish, odorous
wood ; the small fruit dark with a white bloom, erect on the short sup-
porting branchlet.

J. Sablna, Linn., var. procumbens, Pursh. Rocky banks, trailing
over the ground along our northern borders, with the scale-shaped leaves
less acute, and the fruit nodding on the short, peduncle-like, recurved
branchlet.

J. Chinensis, Linn. Low or medium-sized, dioecious tree of upright
habit ; male plant with numerous branches, the upper ones ascending or
erect, the leaves generally in 3's, stiff and spreading, green or glau-
cous ; female plant with longer and more distant branches, the leaves
shorter and more appressed and in pairs; berries dull-violet, small.
China to Nepaul.

* * Leaves all of one sort, in whorls of 3, jointed with the stem, linear
with an awl-shaped, prickly point ; the midrib prominent, also the rib-
like margins.

J. commfriiis. Linn. COMMON JUNIPER. Erect or spreading shrub,
with very sharp-pointed leaves, green below and white on the upper face ;
berries large and smooth. The wild, low, much spreading variety is com-
mon N. in sterile or rocky ground. Var. HIBERNICA, a very erect, tree-
like shrub, forming a narrow column, is most planted for ornament
From Eu. Many cult, forms.

CYCAD FAMILY. 485

15. TAXUS, YEW. (Classical name, from the Greek for a bow : the
tough wood was chosen for bows.) Flowers early spring.

7". baccata, Linn. EUROPEAN YEW. Low tree, with thick, upright
trunk, spreading, short branches, and pointed, dark-green leaves about 1'
long ; when planted in this country forms only a shrub. Var. FASTIGIATA,
IHISH YEW. A singular form, making a narrow column, the branches
appressed ; the leaves shorter, broader, and scarcely in two ranks.

T. tarc/)va, Laws. (T. ADPRESSA). Low tree or shrub, with no dis-
tinct leader, and therefore making a flat top ; leaves short, ovate-oblong,
and very dark-green, 2-rowed ; berries pale-pink. Said to have come from
Japan, but probably only a form of T. baccata.

T. cusp/data, Sieb. & Zucc. Small tree or hardy bush, with the habit of
T. baccata, but looser ; leaves broader and abruptly pointed, leathery in
texture and lighter-colored, 2-ranked on the branchlets, but scattered on
the older growth. Japan.

SERIES II.

FLOWERLESS OR CRYPTOGAMOUS PLANTS.1

Those which fructify without true flowers; that is, with-
out stamens and pistils, and produce spores (simple cells)
in place of seeds.

distinct axis, or stem, growing from the apex, containing
woody matter and ducts, and bearing leaves, or something
answering to leaves.

mostly hollow, furrowed, many -jointed, with mere scales at
the joints united into a sheath in place of leaves ; either
simple or with branches in whorls about the joints ; fructifica-
tion in terminal cone-like spikes, composed of 5-angled, short-
stalked, and shield-shaped scales, each bearing on the under
surface about 6 one-celled spore cases. Contains but one
genus, EQUISETUM, the HORSETAILS or SCOURING RUSHES,
in low places. For the species the student should consult the
Manual. (Lessons, Figs. 493-498.)

trunks, bearing distinct leaves (fronds) on stalks (or stipes)
which are rolled up (drcinate) in the bud, and bear commonly

1 The account of the Flowerless Plants in the original edition was prepared by Professor
D. C. Eaton of Yale College.

FEEN FAMILY. 487

on the under surface or on the edges the simple fructification,
consisting of 1-celled spore cases (technically called sporangia)
variously grouped in dots, lines, or masses (called sori or fruit
dots) and containing but one kind of minute, 1-celled, powdery,
numerous spores, which are discharged when the sporangia
finally split open. A large family, most abundant in warm
and moist 'regions.

[The divisions of a pinnafifid frond are properly called segments; of
a pinnate frond, pinnae ; of a 2-3-4-pinnate frond, pinnules or ultimate
segments. The stalk of the frond is a stipe; its continuation through the
frond, the rhachis ; its branches, partial or secondary rhachises. A rha-
chis bordered by the leafy portion becomes a midrib, which may be primary,
secondary, etc.']

I. POL YPODIUM SUBFAMILY. Characterized by stalked
spore cases, having a vertical, incomplete, many-jointed, elastic
ring, which straightens at maturity, breaking open the spore
case transversely, and so discharging the spores. Spore cases
rarely if ever on very narrow thread-like branches ; the fruit
dots often covered by a scale-like involucre (the indusium).

§ 1. No definite fruit dots, but the spore cases in large patches on the under surface of
the fertile frond, or entirely covering the under surface ; no indusium.

1. ACROSTICHUM § CHRYSODIUM. Fronds simple or pinnately branched, with retic-

ulated veins ; spore cases covering the whole under surface of the frond, or of its
upper divisions.

2. PLATYCERIUM. Fronds irregularly forking ; veins reticulated ; spore cases in large

patches on special portions of the under surface.

(sori) placed on the veins or at the ends of the veins, but without indusium of
any kind.

3. POLYPODIUM. Fronds simple or pinnate, rarely twice pinnate ; veins free or retic-

ulated ; fruit dots round or roundish, at the ends of the veins, or at the point where
several veins meet (anastomose). Stalk articulated to the rootstock, and leaving a
distinct scar when decayed away.

SELAGINELLA FAMILY. 508

CXLI SELAGINELLACE^l, SELAGINELLA FAMILY.

Low, moss-like, often creeping plants, with scale-like leaves
(mostly 4-rowed, the alternate rows often of smaller leaves),
differing from the last family chiefly in having 1-celled spore
cases which contain two kinds of spores (the nature of which
need not be explained here). (Lessons, Figs. 513-515.) One
genus :
1. SELAGINELLA. (Name a diminutive of Selago, a species of

Lycopodium.) Species over 200; the greater part tropical.
§ 1. Native species.

S. nip^stris, Spring. Exposed rocks ; a common moss-like little
evergreen; stems and densely tufted branches l'-2' high; leaves awl-
shaped, marked with a narrow furrow on the back, and tipped with a
minute bristly point ; spikes four-cornered.

S. apus, Spring. Damp places in meadows; common, especially S.;
very delicate ; stems 2'-4' high, sparingly branched ; leaves 4-rowed, those
of the side rows spreading horizontally, scarcely 1" long, ovate with the
upper side larger, minutely serrulate ; intermediate ones half as large,
erect, very acute ; spikes 2 "-6" long. Often cult, as S. densa.

§ 2. Cultivated, mostly tropical species, seen in conservatories; much
branched ; leaves of the branches four-rowed, two side rows of spreading
leaves set apparently edgewise, and two upper rows of smaller appressed
leaves. Spike four-cornered, at the ends of the branchlets.

* Stems trailing, sending out rootlets nearly up to the end.
S. Kraussiana, A.Br. (LTCOP6DIUM DENTICUL\TUM of the florists.) The
commonest conservatory species, used for edgings, etc. ; stems very long,
articulated beneath each branch ; branches distant, bearing a few short
forked branchlets, which are 2r-3" broad, their leaves closely placed in
each row ; leaves bright green, the larger ones oblong-ovate, acute, rounded
ou the upper side, nearly straight on the lower, minutely denticulate ;
smaller ones with longer often reflexed points.

* * Stems ascending, only the lower part bearing long rootlets.

S. Martensii, Spring. (LvcordDiuM STOLONfFERUM of florists). Stems
6'-10' long, much branched from the base ; branches bipinnate, with
copious branchlets 2"-3" or even 4" wide ; larger leaves crowded,
obliquely ovate, the upper side broadest, obtuse, entire ; smaller ones
ovate, with a slender often recurved point.

* * * Stems erect, or nearly so, rooting only at the very base.

S. erypthropus, Spring. Stalk 2 '-6' high, bright red, having a few closely
appressed red leaves, and bearing at the top a broad frond-like stem pin-
riately or pedately divided into a few 2-3 times pinnate branches, with
very numerous extremely crowded branchlets l/'-lo" wide ; leaves closely
imbricated, obliquely ovate-oblong, curved upward, rather obtuse, ciliate ;
smaller ones ovate, with long straight points.

* # # # Stems in a dense, nest-like tuft, not rooting j branches often curl-
ing up when dry.

S. lepidophy/la, Spring. BIRD'S-NEST Moss, RESURRECTION PLANT. It

is a nest-like ball when dry, but when moist it unfolds and displays the
densely 2-3-pinnate, elegant, fern-like branches radiating from a coiled-
up central stem ; the leaves white-margined, closely imbricated, round-
ovate, obtuse. Texas, W. and S,

The Botanist's Microscope

Designed to be used with
the Botanical Text-
Books published by
the American Book
Company.

This convenient instrument,
devised and manufactured first
for the use of the students in
Harvard University, has
given so great satisfaction there, and elsewhere, that we have
made arrangements by which we are able to offer it to students
in all parts of the country at a very reasonable price.

A thousand things about forest, field, or garden afford
objects of intense interest for daily study, and a good Micro-
scope furnishes the best means for unlocking their secrets. Of
this Microscope the late Dr. GRAY said : "I do not think any-
thing better can be made for the money."

This Microscope is attached to a box, one and a half inches
high and less than four inches long, into which it is neatly
folded when not in use. The needles are used for dissecting
flowers or other objects too small to be otherwise handled for
analysis.

OUTLINES OF BOTANY
$i.po

By ROBERT GREENLEAF LEAVITT, A.M., of

the Ames Botanical Laboratory. Prepared at the request
of the Botanical Department of Harvard University

Edition with Gray's Field, Forest, and Garden Flora $1.80

Edition with Gray's Manual of Botany 2.25

THIS book covers the college entrance requirements in
botany, providing a course in which a careful selection
and a judicious arrangement of matter is combined with
great simplicity and definiteness in presentation.
*|[ The course offers a series of laboratory exercises in the
morphology and physiology of phanerogams ; directions for a
practical study of typical cryptogams, representing the chief
groups from the lowest to the highest ; and a substantial
body of information regarding the forms, activities, and re-
lationships of plants and supplementing the laboratory studies.
*|J The work begins with the study of phanerogams, taking
up in the order the seed, bud, root, stem, leaf, flower, and
fruit, and closing with a brief but sufficient treatment of
cryptogams. Each of the main topics is introduced by a
chapter of laboratory work, followed by a descriptive chapter.
Morphology is treated from the standpoint of physiology and
ecology. A chapter on minute structure includes a discussion
of the cell, while another chapter recapitulates and simplifies
the physiological points previously brought out.
^| The limitations of the pupil, and the restrictions of high
school laboratories, have been kept constantly in mind. The
treatment is elementary, yet accurate ; and the indicated
laboratory work is simple, but so designed as to bring out
fundamental and typical truths. The hand lens is assumed
to be the chief working instrument, yet provision is made for
the use of the compound microscope where it is available.

A BRIEF COURSE IN
GENERAL PHYSICS

$1.20

By GEORGE A. HOADLEY, A.M., C.E.,
Professor of Physics, Swarthmore College

A COURSE, containing a reasonable amount of work for
an academic year, and covering the entrance require-
ments of all of the colleges. It is made up of a reliable
text, class demonstrations of stated laws, practical questions
and problems on the application of these laws, and laboratory
experiments to be performed by the students.
^[ The text, which is accurate and systematically arranged,
presents the essential facts and phenomena of physics clearly
and concisely. While no division receives undue prominence,
stress is laid on the mechanical principles which underlie the
whole, the curve, electrical measurements, induced currents,
the dynamo, and commercial applications of electricity.
*f[ The illustrative experiments and laboratory work, intro-
duced at intervals throughout the text, are unusually numerous,
and can be performed with comparatively simple apparatus.
Additional laboratory work is included in the appendix, to-
gether with formulas and tables.

HOADLEY'S PRACTICAL MEASUREMENTS IN
MAGNETISM AND ELECTRICITY. $0.75

THIS book, which treats of the fundamental measurements in elec-
tricity as applied to the requirements of modern life, furnishes a satis-
factory introduction to a course in electrical engineering for secondary
and manual training schools, as well as for colleges. Nearly 100 experiments
are provided, accompanied by suggestive directions. Each experiment is
followed by a simple discussion of the principles involved, and, in some
cases, by a statement of well-known results.

Elementary Chemistry . $1.10

Laboratory Manual . . $o 50

THESE two books are designed to form a course in
chemistry which is sufficient for the needs of secondary
schools. The TEXT-BOOK is divided into two parts,
devoted respectively to inorganic and organic chemistry.
Diagrams and figures are scattered at intervals throughout the
text in illustration and explanation of some particular experi-
ment or principle. The appendix contains tables of metric
measures with English equivalents.

^| Theory and practice, thought and application, are logically
kept together, and each generalization is made to follow the
evidence upon which it rests. The application of the science
to human affairs, its utility in modern life, is also given its
proper place. A reasonable number of experiments are in-
cluded for the use of teachers by whom an organized laboratory
is unobtainable. Nearly all of these experiments are of the
simplest character, and can be performed with home-made
apparatus.

«jj The LABORATORY MANUAL contains 127 experi-
ments, among which are a few of a quantitative character. Full
consideration has been given to the entrance requirements of
the various colleges. The left hand pages contain the experi-
ments, while the right hand pages are left blank, to include
the notes taken by the student in his work. In order to aid
and stimulate the development of the pupil's powers of observa-
tion, questions have been introduced under each experiment.
The directions for making and handling the apparatus, and
for performing the experiments, are simple and clear, and are
illustrated by diagrams accurately drawn to scale.

LESSONS IN PHYSICAL
GEOGRAPHY

By CHARLES R. DRYER, M.A., F.G.S.A., Professor
of Geography, Indiana State Normal School

$1.20

SIMPLICITY and accuracy constitute two of the chief
merits of this text-book. Moreover, much of the gene-
ralization, which is the bane of all text-books, has been
avoided. The physical features of the earth are grouped
according to their causal relations and the functions which they
perform in the world economy. The characteristics of each
group are presented by means of a typical example, which is
described in unusual detail. Many realistic exercises are in-
troduced to direct the student how to study the thing itself,
whenever practicable, or some experimental or pictorial repre-
sentation of it. These exercises include both field and labora-
tory work, and should be made fundamental rather than
supplemental.

^[ The order of general topics is the Planet Earth, the Land,
the Sea, the Atmosphere, and Life, and each topic is treated
with such fullness that it enables the teacher who has not
had a special course in geography to teach the subject in-
telligently. At intervals throughout the book there are in-
troduced discussions of the consequences which follow the
conditions described, and chapters upon Life, containing a full
treatment of the controls exerted by geographical conditions
upon plants, animals, and men.

^j The book is eminently readable. The style is less formal
and dogmatic than is usual in a scientific text-book, and
approaches that which a teacher uses in conversation. The
appendix contains directions for laboratory exercises, full in-
formation in regard to the best material for the equipment of
a geographical laboratory, and a reference list of the available
literature upon the subject. The book is profusely illustrated.

THESE volumes correspond to the four subdivisions re-
quired by the College Entrance Examination Board,
and by the New York State Education Department.
Each volume is designed for one year's work. Each of the
writers is a trained, historical scholar, familiar with the con-
ditions and needs of secondary schools.

^[ The effort has been to deal only with the things which
are typical and characteristic; to avoid names and details
which have small significance, in order to deal more justly
with the forces which have really directed and governed man-
kind. Especial attention is paid to social history, as well as
to the movements of sovereigns and political leaders.
^\ The books are readable and teachable, and furnish brief
but useful sets of bibliographies and suggestive questions.
No pains have been spared by maps and pictures, to furnish
a significant and thorough body of illustration, which shall
make the narrative distinct, memorable, and clear.

CATALOGUE OF HIGH
SCHOOL AND COLLEGE

TEXT-BOOKS

Published Complete and in Sections

WE issue a Catalogue of High School and College Text-
Books, which we have tried to make as valuable and
as useful to teachers as possible. In this catalogue
are set forth briefly and clearly the scope and leading charac-
teristics of each of our best text-books. In most cases there
are also given testimonials from well-known teachers, which
have been selected quite as much for their descriptive qualities
as for their value as commendations.

^[ For the convenience of teachers this Catalogue is also
published in separate sections treating of the various branches of
study. These pamphlets are entitled : English, Mathematics,
History and Political Science, Science, Modern Languages,
Ancient Languages, and Philosophy and Education.
^j In addition we have a single pamphlet devoted to Newest
Books in every subject.

^j Teachers seeking the newest and best books for their
classes are invited to send for our Complete High School and
College Catalogue, or for such sections as" may be of greatest
interest.

^[ Copies of our price lists, or of special circulars, in which
these books are described at greater length than the space
limitations of the catalogue permit, will be mailed to any
address on request.
