PREFAUE. 



Among the happiest days of our childhood were those devoted to the 
study of Botany. Pure sunshine rests upon the memory of those rambles 
in the fields and woods, amid the opening flowers of Spring, and then in 
the gay profusion of advancing Summer, in which we made acquaintance 
with many a floral gem before unknown. We love to think of that wild 
woodland lake where first we saw the sparkling Sundew, the quaint 
Sarracenia, and the fair Nymphaea, resting on the bosom of the waters ; 
or of that lowly dell by the brookside, where the Yellow Violet, the 
Hepatica, and the Bloodroot bloomed ; or of that craggy mountain, 
where, among the rocks, the Columbine hung out its scarlet flowers. 
Then returning home with our gathered treasures, how we entered with a 
will upon the work of Analysis, toiling for hours as no schoolmaster could 
have compelled us to do, being attracted to the task by the very love of it 
alone. Here, then, we have at least one department in learning whose 
earnest pursuit is so congenial to the affections and tastes of the mind as 
to be no irksome task, but a pastime, — a perpetual feast; and this not 
only to maturer minds, but to the season of early youth even in a higher 
degree, since then the objects of nature are especially invested with the 
charms of novelty. 

Let it not be said, however, that Botany attracts such willing votaries 
because it requires no labor, no persevering effort. No science is more 
intricate or profound. It cannot be understood except by vigorous and 
persevering effort. Consequently, in its successful pursuit there is disci- 
pline for the mind as well as for the body; and since the subject itself is 
replete with refinement and beauty, and fresh from the hand of God, its 
pursuit must also conduce to the invigoration of the moral nature. 

If, then, it be desirable to preoccupy the minds of our children with 
controlling ideas of purity, refinement, and moral beauty, — with exalted 



PREFACE. 



thoughts of God, habits of mental activity, strength of judgment, and 
decision of character; and, moreover, to do all this by means of a study 
whose path, in a double sense, is strovvn with flowers, then is the study 
of Botany desirable; and that labor is not in vain which is bestowed 
upon the preparation of a work designed, like the present, for primary 
classes, from the ages often to fourteen. 

As the title implies, we have aimed to represent to the eye nearly every 
subject or form treated of, or described in these Lessons. But, notwith- 
standing the copiousness of these illustrations, neither the teacher nor the 
pupil will be satisfied to rely upon their aid alone. Nature alone can 
afford the proper illustrations in the study of Nature's works, and it is 
only by comparison with the living specimen that eitlur the picture or 
the description becomes intelligible. Therefore let specimens in unlimited 
number accompany every botanical recitation. 

Most of the figures are original. Others have been derived from Maout, 
Payer, Richard, Balfour, Lindley, and a few, by permission, from Darl- 
ington's u Weeds and Useful Flants." 

Finally, to the children and youth of our country, gathered in schools 
of every name, this humble volume is dedicated, with confident belief that 
it will prove to many of them a source of intellectual and moral culture 
as well as of pure and rational delight.

LESSON I. 

THE LEAF, AND ITS PARTS. 




blade. 



Fig. 1. Leaf of the Quince. 

1. We have before us the picture of a Quince leaf, care- 
fully drawn from nature. It is of a rich green color, very 
pleasant to the eye. Its outlines are full, even, and grace- 
fully curved, and its upper surface is smooth and naked. 
Although it is indeed but one leaf, yet it seems to be made 
up of three parts — £, p, ss. 

2. The upper part, b^i& broad and thin, and is called the 



10 OBJECT LESSONS IN BOTANY. 



blade. The upper end of the blade is the apex, and the 
lower end is the base. You see at once that the outline of 
this blade represents a certain form or figure, with an even 
margin, rounded, and broader at the base than at the apex, 
like the figure of an egg. So it is called an egg-shaped leaf; 
or, to use a softer word, ovate. 

3. Now see how this blade is supported. At the base it is 
suddenly narrowed to a foot-stalk, which is properly called 
the petiole. You see that this part of the leaf is narrow and 
slender, and in this leaf terete, or cylindrical, in form. But in 
some kinds of leaves it is flattened. Remember its name, — 
petiole. 

4. Lastly, at the base of the petiole you notice a pair of 
little leaf-like bodies, one on this side and one on that. These 
we call the stipules. Stipules, then, are always in pairs, and 
placed at the base of the petiole. Their shape is quite 
various. 

5. Thus, when a leaf is complete, it consists of a blade, a 
petiole, and a pair of stipules. But you will not find every 
kind of leaf complete. Many sorts have no stipules at all. 
Can you find stipules on the leaves of the Lilac? Some 
leaves, moreover, have not even a petiole. See the leaves of 
Phlox. Such leaves are said to be sessile, that is, sitting. 

1. What is the color of the leaf cf the Quince bush? What is the color 
of leaves generally ? Ans. Green, of lighter or darker shade. What of the 
outline of this leaf? — its upper surface? 

2. What is the blade t — the apex ? — the base ? What is the figure of th* 
blade? 

3. How is the blade supported? Describe the foot-stalk. Tell its real 
name. 

4. Describe the stipules. 

5. Now state the three parts of a complete leaf. Do aU kinds of leaves 
have stipules ? Do the leaves of the Lilac ? — of St. Johnswort, &c. ?— of the 



VEINS OF THE LEAP.

LESSON II. 

VEINS AND VENATION OF THE LEAF. 

6. The blade of the Quince leaf (Fig. 2) shows many veine 
running through it, and branching all over it. Examine 




Fig. 2. Leaf of the Quince, showing the veins. 

them. First, the petiole seems to be extended and continued 
right through, from the base to the apex, forming the largest 
vein in the leaf. This is the midvein. 

7. Next observe several large branches sent off from this 
midvein on both sides, right and left. These are the vei&ilels. 
Now, looking at these veins, their arrangement reminds us of 
a feather, and we call such leaves feather-veined. Therefore, 

Violet? Do all kinds of leaves have petioles? — of Phlox, for example! 
VVhat do you understand by sessile leaves ? 

6. Describe the midvein of the Quince leaf. 

7. Describe the veinlets. What is the feat her- veined venation ? 



12 



OBJECT LESSONS IN BOTANY. 



we may say that the feather- veined venation consists of one 
midvein branching into veinlets. This is very common. 

8. Thirdly, the veinlets themselves send off little branches 
(branchlets) on their right and left, and we call these the 
veinulets. These again and again may divide, and finally, all 
the little divisions unite again, forming a complete net-work 
all over the leaf. Thus we learn what a net-veined leaf is. 




Fig, 8. The Willow leaf. Some of the veinulets are shown. 

9. Here is a picture of the Willow leaf (Fig. 3). You can 
point out all its parts, and the three kinds of veins in it. In 




Fig. 4. Leaf of the Red-bud (Gercis). 



8. What are the veinulets? When is a leaf said to be net veined? 



VENATION OF THE LEAF. 



13 



the next cut (Fig. 4), representing the Judas-tree or Red- 
bud leaf, you see a different venation. 

10. At the base of the blade the petiole seems to divide 
all at once into five large veins, each running through, one 
to the apex, and four to the margin. In this case the vein- 
ing (that is, the venation) is compared to the division of the 
hand (or palm of the hand) into fingers, and so named pair 




Fig, 4 <z. Leaf of Sweet-gum {Liquidambar). 

mate venation. Therefore, you may say that the palmate 
venation consists of about five veins starting together at the 
base of the blade, each one branching into veinlets and 
veinulets. Fig. 4 a is a lobed leaf of the Liquidambar tree

with palmate venation. Maple leaves are very familiar ex 
amples of the same. 

11. Our next figure (5) represents the leaf of 
the Tulip. How very different is its venation ! 
How smooth, even, and polished its surface ! The 
veins all run side by side, from base to apex, in 
graceful and regular curves. They are so nearly 
parallel, that this kind of venation is called the 
parallel venation. Look at the grass leaves, the 
Corn leaves, and the Palm leaves, and see the 
same kind of venation.

Fig. 6. Leaf of the Climbing Fern. 



12. Let us examine one other kind of venation, and the 
list will be complete. Here is a cut showing the leaf of

Now repeat the names of the five or six kinds of venation.

Climbing Fern (Fig. 6). To say nothing of the five veins 
(which are palmate, as in the leaves of Sweet-gum, Fig. 4 a), 
you may notice the veinlets, how they fork and run to the 
maigin, without uniting again to form a net-work. This is 
the forked venation. Yon will find this sort in nearly ail 
the Ferns. 



LESSON III. 

FORMS AND FIGURES OF LEAVES. 

13. You have already noticed that the form of the Quince 
leaf, and of most others, is a thin, flat expansion, presenting 
a large surface to the air. A few plants have thick, solid 
leaves, as the leaves of the Live-forevers and Ice-plants 




Fig. 7. Eepresents a branch of Juniper, with awl-shaped leaves (subulate). 
Fig. 8. Leaves of the Fleur-de-lis (Iris) ; they are sword-shaped (ensiform). 
Fig. 9. Leaves of the Scotch Pine; they are needle-shaped (acerose). 

Other plants have slender leaves, as the Pines. See Figs. 
?, 8, and 9. 

13. What is the general form of leaves ? What plants have thick and 
solid leaves? What form of leaves has the Pine? the Iris? the Juniper? 



16 OBJECT LESSONS IN BOTANY. 



14. We also spoke of the figure of the outline of the 
Quince leaf, which is ovate. But you must have observed 
that there is a very great variety in the figure of leaves, af- 
fording a very interesting study. First, we will examine, one 
by one, the figures of the feather-veined leaves (Figs. 10-21.) 




Fig. 10. Ovate leaf of the Pear-tree. 
Fig. 11. Lanceolate leaf of the Flowering Almond. 
Fig. 12. Narrow lanceolate leaf of the Weeping Willow. 
Fig. 13. Deltoid leaf of the White Birch. 

15. The leaf of the Flowering Almond (Fig. 11) is lanceo- 
late. It is narrower than ovate, shaped like a lance, having 
the lower half wider than the upper. This Willow leaf (Fig. 
12) is narrowly lanceolate. The leaf of the Lombardy Pop- 
lar, or of the White Birch (Fig. 13), is so broad at the base 
as to form a three-sided figure, like the Greek letter (A) delta. 
Hence it is a deltoid leaf. 

1 4. What is the figure of the Quince leaf? 

15. Describe the figure of the leaf of Flowering Almond ; of the Weepjag 
WiUow ; of the Lombardy Poplar, &c 



LEAF-FORMS AND FIGURES. 



17 



16. In the next four kinds of leaves you will notice that 
the broadest place is midway between the base and apex. 
Thus the orbicular (Fig. 14), or rounded, leaf is about as 
broad as it is long. The oval leaf (Fig. 15) is about one-third 
longer than broad. This Plum leaf is an example. The el- 
liptical (Fig. 16) is about twice longer than broad, and the 
oblong (Fig. 17) is three or four times longer than broad. 
Here are examples.

Fig. 15. Oval leaf of the Plum-tree. 
Fig. 16. Elliptical leaf of Block Ilaw. 
Fig. 17. Oblong leaf of a Willow. 

17. We next have four varieties of forms which are broader 
towards the apex than base. First, the obovate (Fig. 18), 
like this leaf of the Smoke-tree. Its outline is like that of

the egg inverted. A similar form, but narrower, is the oh 
lanceolate ; that is, the inverted lance-shaped, like the ,ea\ 
of Papaw, or Fig. 19. Next, still narrower, is the spatulate, 
a figure compared to the surgeon's spatula (Fig. 21); and 
lastly, the wedge-shaped, or cuneate, tapering from a broad 
apex to a slender base, as in Fig. 20.

LESSON IV 

FORMS AND FIGURES OF LEAVES. 

19. In many kinds of leaves we find the parts at the base 
more or less enlarged backwards, as you see in this picture

of the Morning-glory leaf (Fig. 22). This is the heart 
shaped, or, more properly, the cordate ]eaf. It is truly an

elegant figure in this and in the Lilac, &c. But sometimes 
this peculiar enlargement at base becomes excessive, and the 
figures more curious than elegant. Such is the arrow-shaped 
figure, called sagittate, having long-pointed base lobes, as 
seen in the Arrow-head (Fig. 47), the Scratch Knot-grass, &c. 
(Fig. 26.)

ed, giving to them a kidney-shaped form, that is, re?iiform ) 
as you see in this Wild Ginger leaf (Fig. 23), and in the 
Pennywort (Fig. 24). The peltate, or shield-shaped leaf (Fig 
25 — another Pennywort) has its base lobes united, and its pet 
iole fixed to the under side. See, also, Nasturtion leaves. 

21. We will next study a class of forms with deeply lobed 
or cleft blades, not well filled up between the veinlets.

lobcd leaf (Fig. 32), the Mossy-cup Oak has a lyrate leaf, 
having its terminal lobe larger than any other (Fig. 34). 
22. Fig. 35 is the leaf of a kind of Milkweed, called Mid- 

gedium, with sharp lobes pro- 
jecting at right angles to the 
raidvein ; and Fig. 3(5 is of the 
Wild Lettuce, with lobes point- 
ing or hooking backwards. 
Such leaves are called run- 
cinate. The Dandelion has 
I "^/^ v also runcinate leaves. When 

jp=/ a leaf has only shallow lobes, 

as you see in Fig. 33, it ap- 
pears with a wavy outline, 
called undulate. It is a leaf of that beautiful tree called at 
the West, Jack Oak. 




Fig. 36. Leaf of Lactuca elongate, or

LESSON V. 

OTHER FORMS AND FIGURES. 

23. It is now time to learn the difference between a sim- 
ple and a compound leaf. The simple leaf has but one 
blade, as the Quince leaf, and all the leaves which we have 
hitherto noticed. We have now before us a compound leaf, 
one plucked from a Rose-bush (Fig. 39), consisting of several 
distinct blades on one petiole. It has also one pair of stip-

ules, like a simple leaf. This Clover leaf is also compound 
(Fig. 37), having stipules (s), as well as this simple leaf of 
the Shining Willow (Fig. 38). 

24. But here is a leaf, the Celandine (Fig. 40), which is 
almost, but not quite, compound. The blade is feather- 
veined, and deeply divided into several parts, called segments. 
Such a leaf is called pinnatifid. In Fig. 31, the leaf of a 
garden weed (Ambrosia), you observe that the segments are 
themselves pinnatifid, so that the leaf is twice or Tji-pinnatifid 



24. Please define the pinnatifid leaf. The bi pinnatifid. 



24

25. But what form of 
leaf is this (Fig. 41) of 
the Fennel-flower, with 
such a multitude of nar- 
row segments ? You may- 
call it pin-nat-i-sect,& long 
word which signifies dis- 
sected in a pinnatifid 
manner. The Thistle leaf 
is also pinnatisect, al- 
though quite different in 
form.

a pedate leaf of a Pas-

its veins bearing a seg- 
ment, and each lower

figures similar to the net veined, as lanceo- 
late (Fig. 44), orbicular (Fig. 45), cordate 
(Fig. 46), sagittate (Fig. 47), &c. ; but the 
most usual form is the linear , like the Grass 

leaf (Fig. 48), which is long 
and narrow, with sides nearly 
parallel. The sword-shaped 
leaf, or ensiform, differs from 
the linear in having its edges 
vertical, not horizontal as 
other leaves. See the Iris. 8.

margins entire and even, as in the Quince leaf, or the LilyT 

But most leaves are notched in various ways. For example,

like a saw, with the teeth projecting forward. Such a mar- 
gin is said to be serrate, or, if the teeth are quite small, ser- 
rulate. When the teeth point neither forward nor back- 
ward, but outward, we call the margin dentate, or toothed ; 
and if the teeth are quite small, denticulate. See Figs. 49, 
50, 51, &c. 

31. Some leaves are margined with rounded and blunt 
teeth, and we call them crenate (Fig. 52) ; or, if such teeth 
are very small, crenulate. 

32. In Figs. 13 and 50, you see that the teeth themselves 
are again toothed, an arrangement called doiibly serrate. 
So we may find leaves doubly dentate or doubly crenate. 
Thus we have described seven modes or styles of border- 
ing. Several other modes are found described in the larger 

botanies.

33. It is also necessary to be acquainted with the vari« 
ous forms of the apex of leaves. This diagram (Fig. 56) 
will assist the memory. The apex may be acuminate, end- 
ing in a long, tapering point; or cuspidate, suddenly con- 
tracted to a sharp, slender point; mucronate, tipped with 
a spiny point ; acute, simply ending with an angle ; obtuse, 
blunt. 

34. Or the leaf may end without a point, being truncate, 
as if cut square off; retuse, wdth a rounded and slightly de- 
pressed end where the point should be ; emarginate, having 
a small notch at the end ; obcordate, having a deep inden- 
tation at the end. See also, and explain, the diagram of 
the bases of leaves (Fig. 57). 



LESSON VII. 

COMPOUND LEAVES. 

35. A compound leaf consists of several distinct blades 
borne on one petiole. (See Lesson V., first paragraph.) 
These separate blades are called leaflets. You notice that in 
Fig. 39 each of the five leaflets has its own foot-stalk, called 
petiolule, and its own midvein, &c. 

36. The Rose leaf (Fig. 58) is pinnately compound, or sim-

ply pinnate, having several leaflets 
arranged along both sides of the com- 
inon stalk. This common stalk, an- 
swering to the mid vein of a simple 
leaf, is called the rachis. 

37. Among pinnate leaves, there 
are, at least, three important distinc- 
tions. Observe the Figs. 59, 60, and 
61. One of them ends with an odd 
leaflet, and is called odd-pinnate. 
Another ends with a pair of leaflets, 
and is equally pinnate. Another still 
has its alternate leaflets smaller, and is interruptedly pinnate,

38. Every one knows that the number of leaflets in the 
Clover is three; also in the Bean, and in this figure (62) of 
the Desmodium leaf. Such leaves are called ternate. Bat 
here the pupil will notice another important distinction. In 
this Desmodium leaf, the odd leaflet is stalked, and is said 
to be pinnately ternate ; in Clover, the 
odd leaflet is nearly sessile, like the 
other leaflets ; this is palmately ternate. 




Fig. 64. Honey Locust. 



Fig. 65. Poison Hemlock. 



39. Fig. 64 represents a li-joinnate (that is, twice pinnate) 
ieaf of Honey Locust. The simple leaflets seem to have 
each become itself a pinnate leaf. And still more compound 
is this Poison Hemlock leaf, being tri-pinnate, or thrice pin- 
nate (Fig. 65). In the same manner, we have bi-ternate and 
tri-ternate.

tiately and the palraately ternate ?

leaf? A tri-ternate ? 



FORMS AND FIGURES OF LEAVES.

40. All the above forms of com- 
pound leaves, except the Clover, 
are founded on the pinnate vena- 
tion ; but the palmate venation 
gives us the palmately ternate 
(Clover, already described) ; the 
quinate^ with five leaflets; the sep- 
tinate, with seven leaflets, &c. 
See the leaves of Horse-chestnut, 
of Hemp, and of this Lupine (Fig.

LESSON VIII. 

SESSILE LEAVES— FORMS OF STIPULES. 

41. We have already stated (Lesson I., § 5) that many 
-eaves are without petioles (foot-stalks), or, in other words, are 
sessile. The figures presented on page 33 exhibit some of the 
modes of attachment peculiar to sessile leaves. In Fig. 80 
(an Aster) you see leaves of the form called spatulate (Lesson 
III., § 5), having large base lobes nearly clasping the stem 
at the point of attachment. Such leaves are said to be am- 
plexicaul (stem-clasping). 

42. In the next figure (81, Bellwort) the leaves are ellipti- 
cal, parallel- veined, and not only clasp the stem at base, but 
the lobes there grow together on the opposite side, appearing 
?s if the stem passed through the leaf; that is, perfoliate. 

40. What kind of venation have all these forms ? On the palmate vena 
tion what forms are founded ? 

41. When are leaves said to be sessile? Define an amplexicarl lea£ 

42. Can yon define a perfoliate leaf?

43. In Fig. 82 (Trumpet Honeysuckle) the leaves placed 
opposite are joined together by pairs, base to base. Such 
are connate leaves. 

44. The forms of the petiole, when the petiole exists, are 
also various. Generally, it is merely a rounded, slender 
stem, but you will often find it flattened. Have you ever 
noticed the structure of the Aspen (Poplar) leaf, which so 
easily flutters in the gentlest breeze ? Its petiole is flattened 
vertically, so that its edges turn sky-ward and earth-ward. 
Such a form of leaf-stalk is called compressed, and it must be 
very nicely balanced in order to hold the blade at rest. 

43. When are leaves said to be connate ? 

44. What is the usual form of the petiole ? Carefully describe the petiole 
«f the Aspen.

45. A winged petiole is flattened horizontally. A sheath- 
ing petiole embraces the stem with its winged edges like a 
sheath. Yon can find plenty of examples of these forms.

46. Let us now study more particularly the varying forms 
of the stipules. We have already defined them. (See Les-

and a pair of small, narrow stipules (s). Fig. 86 is a Knot-

LESSON IX. 

ARRANGEMENT OF LEAVES AND BUDS. 

48. If you carefully notice how the leaves are distributed 
over any plant, — the Corn plant, for example, — you w T ill soon 
admire their order and exactness in this respect. At first 
view, we might suppose their positions all accidental ; but it 
is not so, and much of the peculiar aspect of the plant de- 
pends upon this circumstance. 

49. In the Corn plant, or in this figure of Lady's-slipper 
(89), we find the leaves alternate, — that is, one on this side, 
the next one higher and on that side, and so on. So it is in 

46. Stipules ; can you repeat the definition? Describe the stipules of the 
Rose. Describe the stipules of the Pansy. 

47. Describe the stipules of the Pear. Stipules of Knot-grass — what 
called ? Stipules of Grass — what called ?

the Elm, Cherry, Willow, and many other plants. But it 
would be more accurate to say that the arrangement, in all 
these cases, is spiral. (See Class Book, § 224.)

50. In the Maple, Lilac, Phlox, and in this figure of the 
Synandra (90), a wild western plant, the leaves are opposite ; 
that is, two opposite ones stand at each joint. The Meadow 
Lily, and this Medeola (Fig. 92) of the New England woods, 
have whorled ovverticillate leaves; that is, several in a circle 
at each joint. Again, look at this Larch (Fig. 91), the Pines, 
<fcc, whose leaves, gathered in little tufts or bundles, are 
fasciculate.

VERNATION.— LEAF-BUD 



37 




51. In early spring, before the leaves are expanded, we 
find them folded up in the buds. This is called the verna- 
tion of the leaves (from the Latin vernus, spring). In this 
condition the young leaves are closely packed in many curi- 
ous modes, which are described in the Class 
look, §§209-211. 

52. If we dissect and carefully examine a 
swelling leaf-bud in early spring, we observe 
in the midst of it a tender point of a growing 
pith, bearing and covered by many circles of 
little leaves and scales, packed as close as 
possible. Fig. 91 shows a twig with two 
buds as if split through the axis, exhibiting 
the pith, growing point, young leaves, and 
scales. 

53. According to this figure and the next 
(91), buds are either terminal (£), situated at 
the end of the stem or twig, or lateral (a), 
situated on the side. But we must more care- 
fully define the position of the lateral buds, 
you that they are amllary^ or located in the axil of a leaf, 
you would not understand, until knowing that the axil of a 
leaf is the upper angle between the leaf-stalk and the stem. 
(See J, Fig. 90.) Now, remember this rule, which you may 
soon confirm by your own observation, that there is a hud at 
the termination of every sUm or branch, and in the azril of 
every leaf.

APPENDAGES, ETC. 

54. The tendril is a very common appendage. Yon ha^c 
Been it in the Grape-vine, the Pea-vine, the Greenbrier, <tc 
It is like a stout, green thread, reaching out its curved point 
like a finger, until it touches some object; then it quickly 
entwines itself around it, and soon acquires a firm hold. We 
do not find tendrils on any plants except such as, like vines, 
are too weak to stand without support.

55. But tendrils are quite various in habit. Those of the 
Pea (Fig. 96) grow from the extremity of the rachis. Those 
of the Greenbrier (Fig. 95), from the base of the leaf-stalk, in 
the place of stipules ; those of the Grap£-Vines are opposite the 
leaves, in the place of clusters.

prickles, as if in self defence. See the Thorn-bush (Fig. 99). 
where the long straight thorns come from the axils of the 
leaves, and are woody. The 
terrible thorns of the Honey 
Locust (Fig. 100) are branched. 
Those of the common Locust 
are in the place of stipules. 
Those last mentioned, and all 
others which originate with 
the leaves (as in Berberis, 
Thistle, &c), are more prop- 
erly called spines. 

57. As for the Rose and 
Bramble, they are armed with 
prickles, which are horny in 
substance, connected with the 
bark only, not with the wood. 
(See Fig. 101.) 

58. Glands are little wart-like bodies which secrete the 
peculiar fluids of the plant, sometimes imbedded in the leaf 
or the rind of the fruit, as in the Lemon, where it is filled 
with a fragrant volatile oil ; sometimes raised on a hair 
(Figs. 102, 103), as in Sundew, exuding a clammy liquid. 

59. Stings are piercing hairs, having a bag at the base 
filled with an acrid fluid. "When touched the tip breaks off, 
the hair penetrates the skin, and the poison is injected into 
the wound. (See Fig. 106.)

ORGANS OF THE FLOWER. 



03. To-day we commence the study of the beautiful flower 
We have before us the Meadow Lily (Fig. 107), whose or- 
gans are large and perfectly 
distinct. Observe, in the first 
place, that its brighter colors 
form a striking contrast with 
the soft green of the leaves. 
The coloring, the structure,

and the fragrance of the flower are all worthy of its Infinite 
Creator, and remind us of his wisdom and goodness. 

64. As to the structure of the flower, it is always com- 
pound, being composed of several or many pieces nicely 
adapted to each other. In this Lily, for example, you may 
count thirteen pieces, or organs, attached in a close order to 
the summit of the flower-stalk (Fig, 113, a). You may call 
the flower-stalk the peduncle, and the point of attachment (r) 
the torus, or receptacle. The former is the better name. 

65. Two circles of leaf-like organs form the envelopes of 
this flower, and each circle consists of three pieces. The 
outer circle is the calyx, and the three pieces which compose 
it are called sepals (s, s, s). The inner circle is the corolla, 
and the three pieces which compose it are called petals 
(p,p,p). In the Lily and some other flowers the calyx is 
colored like the corolla. But it is not so generally. In the 
Rose, Strawberry, Pink, and in this Trillium (Fig. 108), the 
calyx is green, while the corolla is almost always distin- 
guished by some brighter color. 

66. Now, taking both calyx and corolla together as a 
whole, we call them the perianth (a Greek word, meaning 
around the jtower). This name is very convenient when we 
speak of such flowers as this, where the calyx and corolla are 
not much different. 

63. What is the subject of to-day's lesson ? What do you notice as to the 
color of the flower ? 

64. What is said of the compound nature of the flower? Of how many 
pieces is the flower of the Lily composed? What is the peduncle? Wliwt 
is the torus ? 

65. Will you point out and define the calyx? sepals? Will you point 
out and define the corolla ? petals ? What of the colors of these organs ? 

68. What is the use of the word perianth ? Will you point out and define 
the stamens ? What of their number ? What is the pistil ? How many ? 



OF THE CALYX AND COROLLA. 43 



67. Next within the perianth of the Lily we find six long, 
slender organs of peculiar form and color, called stamens. 
In the Rose yon find a larger number (perhaps one hundred) 
of stamens, while in the Speedwell you find but two. But 
the most common number is five. Count them in the Morn- 
ing-glory, the Bellwort, Primrose, &c. 

68. Lastly, this central, club-shaped body (j?), here as long 
as the stamens, but of totally different- structure, is thepistil. 
Other flowers have mox*e than one pistil, as the Pink, which 
lias two , the Rose, which has many. 

69. Thus, we have learned that the flower — at least this 
flower — is compounded of four kinds of organs, those of 
each kind being arranged in a circle by themselves. The 
outer circle, of sepals, constituting the calyx ; the second 
circle, of petals, constituting the corolla ; the third circle, 
the stamens ; the fourth circle, the pistils. 



LESSON XII. 

MORE ABOUT THE CALYX AND COROLLA. 

70. Let us examine the flower of the Pink (Fig. 112), the 
Strawberry (Fig. Ill), the Crowfoot, the Single Rose. In 
either you observe five green sepals, and the same number 
of colored petals. Notice also the positions of those organs, 
— how the petals stand alternating with the sepals, and that 
they are all distinct and separate. This is the general rule, 
but there are many exceptions. 

67. Lastly, review the whole arrangement.

rule as to their relative position, &c.V

71. Often in the petal, and sometimes in the sepal, you 
can distinguish two parts, — namely, the broad, expanded 
part above, called the lamina, and the narrow part at base 
by which it is attached to the torus ; this is the claw (Fig. 
116, c). The petal of the Pink has a long claw; of the Rose 
or Buttercup (Fig. 119), a short one.

like the leaf; as ovate, orbicular, oblong, &c, and some-

calyx (c) appears as a green tube, with five notches or teeth 
at the top. It is evident that this is made up of five sepals

similar words, used in the same sense. Opposed to these

though composed of several pieces, is described as a single 
organ, and its lower part, formed by the united claws,

LESSON XIII. 

ABOUT ADHESIONS. 



78, The pupil will here find discussions more important 
and intricate. But if lie bring to the task eyes determined to 
soe, and a mind determined to understand, the difficulties 
will soon vanish. 

79. Cohesion^ as taught in the last lesson, implies the union 
of organs of the same kind, as sepals with sepals, petals with 
petals; but adhesion implies the union of one kind of organ 
with another kind.

81. Now we take it for granted that all the organs of the 
flower have their starting-point or origin at the same one 
point, namely, at the torus (2, Fig. 129), hence in this figure 
of the Golden Currant, it is understood that from t to u the 
calyx, corolla, stamens, and pistil, adhere together ; from ?. 
to v, the calyx, corolla, and stamens, adhere ; and at v, a I 
the organs are separate, that is, free. Observe the saint * 
structure in the Ear-drop (Fig. 130). 

82. In this and like cases, the calyx is said to be superior, 
because it seems to stand upon the pistil (ovary) and fruit, 
but the more correct term is, calyx adherent.

quainted with now. When the stamens adhere to the calyx

meaning " around the pistil"). Otherwise, w T hen free, they 
arc said to be hypogynous, meaning " under the pistil." 

84. Now study attentively these figures, or rather, the 
flowers themselves. The figures are sections, i. #., show the 
flowers as if split. Fig. 132 (the Violet) shows the stamens 
hypogynous and the organs all free. Fig. 133 (the Pear] 
shows the stamens perigynous, adhering to the calyx. Fig. 
131 (the Saxifrage) shows the stamens perigynous and the 
calyx half adherent. Do not fail to examine many flowers 
until these troublesome terms become familiar, for these 
distinctions are very important. 



LESSON XIV. 

FORMS OP PERIANTH. 

85. While all flowers agree in certain general characteris- 
tics, so that you are never at a loss to recognize any one of 
them as a flower, yet in form and fashion they appear in 
infinite variety, each form endowed with its own peculiar 
grace. It is impossible to describe or name every form, but 
we will endeavor to reduce them to a few classes of forms. 

86. Notice first that all forms are either polypetalous or 
gamopetalous, as already described (§ 75). Again, they are 
either regular or irregular. Compare the flower of Flax

and Pea. The former is equally and similarly developed all 
around, and each petal is like all the other petals. It is a 
'regular flower. The Pea flower (Fig. 13S) is unequally 
developed, some of the petals differing in form and size from 
the others, as shown in Fig. 139 ; therefore it is irregular. 

87. The figures at the head of this page represent four 
different styles of corollas which are polypetalous and regu- 
lar. Fig. 134 (Wild Apple) is a rosaceous corolla, that is, 
rose-like, having five short-clawed petals. Fig. 135 (Wall- 
flower) is a cruciform (cross-shaped) corolla, with four long 
clawed petals.

(Atamasco Lily) is a liliaceous corolla, having a six-leaved

alike.

above, very large, called the banner, two smaller petals 
below (&), called the keel, and two lateral petals {a, a), called 
the wings. 

90. We next propose to examine the principal forms of 
gamopetalous corollas. Here we have a beautiful array of 
them. Among the regular forms is, first, the Rotate, wheel- 
shaped or star-shaped, having a very short tube, and a fiat, 
spreading border; as Fig. 141 (Campanula Americana).

95. Tubular, when the corolla is nearly all a slender tube 
with a small border or none at all, as in the Trumpet Honey 
suckle (Fig. 146). 

96. Ligulate (from the Latin ligula, tongue), as if formed 
by splitting the tubular on one side. The notches at the end 
plainly indicate the number of united petals which compose 
it, as also do the parallel seams. See the flowers of the Dan- 
delion (Fig. 147), also of Cichory. 

97. Labiate (Latin labium, lip), resembles the mouth of an 
animal. It is a very irregular corolla, having the petals of 
dissimilar shape and dissimilarly united. See (Fig. 148) a 
flower of Synandra, or Catmint, or Catalpa. In Fig. 149 
(Snap-dragon), the mouth is closed and said to be personate, 
which means mashed. 



LESSON XV. 

CONCERNING THE STAMENS. 

98. Safely infolded within the perianth, we find a number 
of delicate, thread-shaped organs, quite unlike the sepals and 
petals. They are arranged in one or more circles, and called 
the essential organs, because they are absolutely necessary to 
the perfection of the seed. 

94. Describe the salver-form. 95. The tubular. 96. Ligulate.

The central organ (or organs) is the pistil. AVe now propose

pears that the stamen consists of three members. See them

101. The filament is usually of a thread like form (as its 
name, from the Latin filum^ a thread, implies), longer than 
the anther, and more or less elastic. But the filament is no 
more necessary than the stem of a leaf, and is often wanting. 

102. The anther is an oblong body at the top of the lila- 
ment, consisting of two hollow lobes joined to each other 
and to the filament by the oanneetiU (V), which an bo the 
midvein of the leaf. The two lobes are usually marked along 
their outer edge by a seam, which at length opens into the 
cells. This opening, however it takes place, is called the 
dehiscence. If there be no filament, the anther is ses-

103. But dehiscence takes place very variously. When all 
regular, it is a chink running lengthwise along the outer edge, 
as you see in this stamen of a Buttercup (Fig. 163). But 
here, in this stamen of Iris (Fig. 165), it appears on the back 
of the anther (looking towards the petals), and we say that 
the anthers are extrorse, that is, turned outwards. A term 
of opposite meaning is introrse, denoting that the lines of 
dehiscence turn inwards towards the pistil, or at least do not 
turn outwards. For example, the anthers of the Violet 
(Fig. 173). 

104. Moreover, other modes of dehiscence besides chinks 
are occasionally found. The anthers of Berberis, Sassafras, 
fcc. (see Figs. 171, 172), open by lids hinged at the top. The

of the Heath family, open through two little tubes at the top. 
The former is opercular dehiscence, the latter porous. (See 
Figs. 169, 170.) 

105. It is also interesting to notice how the anther is at- 
tached to the filament in various ways. Generally, it is 
innate, that is, seeming to stand erect on the top of the fila- 
ment. Again, it is adnate, which means, attached by its 
back to the side of the filament, as in Buttercups. And 
thirdly, it is joined by a single point in its back to the slender 
tip of the filament, as if lightly balanced upon it. This is the 
versatile anther, common in the Grasses (Figs. 150, 166).

MORE ABOUT THE STAMENS. 

106. The careful student will find a great and interesting 
variety in the number, arrangement, and form of the stamens. 
In regard to number, as we have already seen, the Lily has 
six stamens, the Pink has ten, the Speedwell two, the Indian 
Shot only one. Some flowers have numerous stamens, as the 
Rose with forty, fifty, or one hundred, and the Cactus with

two hundred. Let us learn how to distinguish between 
flowers with definite and with indefinite stamens. Definite, 
when they are not more than ten, indefinite, when more than 
ten, or not readily counted. 

107. The stamens are usually separate and distinct, as in 
the Lily, Rhododendron, &c. (Figs. 150, 152), while in the 
Mallow (Fig. 179), Pea, and other flowers, they grow together, 
forming a tube around the pistil ; in other words, they are 
monadelphous (Greek, monos, one, adelphos, broth orhood). 
The Pea, or Dielytra, is diadelphous, — the stamens in two 
sets ; and the St. Johns wort, polyadelphous, — in three or more 
sets. Another mode of cohesion is seen in the floret of Dan- 
delion (Fig. 180), where the anthers cohere while the fila- 
ments are distinct, i. e., syngenecious.

LESSON XVII. 

THE PLAN OF THE FLOWER. 

112. It is very instructive and delightful to study the 
symmetry of flowers in the way mentioned in the last lesson. 
We are thus led to the discovery of a truth in the science of 
botany at once beautiful and sublime, — worthy of the wis- 
dom of the Infinite Creator. That truth or principle is, that 
all flowers, though infinitely various in form and fashion, 



111. What a symmetrical flower? How is the Lily symmetrical?

are built upon one only plan, and that plan founded in the 
science of numbers. 




Fig. 192. Flower of Hippuris, — one-parted. 

Fig. 193. Circsea Lutetiana ; flower two- parted. 

Fig. 194. Yellow-eyed Grass (Xyris) ; flower three-parted. 

113. Let us, then, examine the Flax. Here all the organs 
are in fives. The Circe has them all in twos ; the Iris, in 
threes. And every plant is distinguished in this way by 
some number which we call the radical number, according 
to which its organs are parted. Now in the Mock Orange, 
or Philadelphus, although the stamens seem to be indefinite, 
still the radical number is four. The stamens occur in many 
circles, with four in each circle, so that these are also in fours. 
As for the pistils, they are evidently four, but so united as 
to form apparently but one. Examine also the Bloodroot. 
Its stamens will be found in fours, the radical number, and 
the stamens of the Apple will be found in fives. So the 
petals of Bloodroot are twice four (8), and of the Magnolia 
twice three (6), or three times three (9). 

114. It is therefore a general law, that when any organ is

multiplied, its new number is only a repetition of the radical 
number. 

115. Also, when any organ is diminished in number, we 
find generally that the deficiency is only apparent, and doee 
not interfere with the law of the radical number. Thus in 
Philadelphus, the one pistil proves to be four growing to- 
gether. In the Lady's-slipper, the radical number is three, 
and the sepals are three, although the two lower ones are 
united almost to the tip into what seems but one. Thus the 
true number is often curiously disguised by cohesions.

mint, while five-parted, the flowers have generally bnt four 
stamens; but on close observation we often find a small 
rudiment of the fifth stamen in its proper place, as if its 
growth had been early stopped. And in Monarda and Catal- 
pa, only two stamens grow up to maturity, while three are 
mere rudiments (Fig. 202). Nevertheless, such flowers are 
said to be unsymmetrical. So the flowers of the Mustard 
tribe. The stamens are in two rows of four in each ; but ol 
the outer row (or circle) two were checked in growth (or 
suppressed, as the botanists say) at the outset. (See Fig. 97.) 
The tendency to symmetry is manifest in all these cases. 

117. We must carefully distinguish between the terms 
unsymmetrical and irregular. The former refers to number 

only, the latter to form and size 
(Less. XIV.). The Mustard 
flower is unsymmetrical but 
not irregular. The Orchis is 
irregular, but not unsymmet- 
rical. Snap-dragon is both 
irregular and unsymmetrical.

how the form of the slender stamen gradually changes to 
the broad petal, the anther becoming smaller and smaLer. 
One can scarcely say where it ceases to be a stamen and 
begins to be a petal. So, also, the petals gradually pass into 
sepals, and in other plants, Peony for instance, the sepals 
just as gradually pass 
into leaves. (See Class 
Book of Botany, § 113.) 

119. This transforma- 
tion of one sort of organ 
into another (always 
from stamen back to- 
wards the leaf) is quite 
common among culti- 
vated plants. It is in 
this mannei that the 
Rose, Carnation, Peony, 
&c, become double, viz., 
by the stamens, and oft- 
en the pistils too, becom- 
ing petals : for in the 
wild state these flowers 
have but five petals. 

120. From these ex- 
amples and others like 
them, we conclude that the different organs of the flower, and 
the leaf also, although commonly very different, have all one 
common nature and origin* or, in other words, the organs of 
the flower may all be considered as transformed leaves.

LESSON XVIII. 

OF THE PISTILS. 




jtlg. 202. Section of flower of Strawberry, — ovaries many, on a raised tome. 
Fig. 203. Section of a Kose, — ovaries sunk into a hollow torus. 

121. The pistils occupy the centre of the flower, at the end 
or centre of the torus. Their number varies in different 
plants from one to one hundred, or ^aore. When they are 
several they stand arranged in a circle like the other organs. 
When they are many they are commonly heaped together in 
a spiral manner, and raised on the conical torus, as in Butter- 
cup, Strawberry, or sunk into the cavity of a hollow one, as 
in Eose. (See Figs. 202, 203.) 

122. The pistil consists, plainly, of three parts, as may be 
seen in Fig. 204. At the top is the stigma (s), at base is the 
ovary (0), and between them is the style {sty). The style

being a mere stalk, like the filament of a stamen or 
the petiole of a leaf, may, like them also, be wanting, 
without loss to the pistil. In this case the stigma is 
sessile (sitting) upon the ovary, as in the pistils c/ 
Anemone (Fig. 207), and of Trillium (Fig. 206).

Fig. 207. Pistils of Eue Anemone (A, thalidroides), — stigmas sessile. 

123. The ovary is a kind of sac or case, enclosing the 
ovules (see Fig. 215, where there is but one, or in Fig. 209, 
where there are five, and Fig. 202, where there are many 
ovaries.) When full grown, the ovary becomes the fruit, and 
the ovules the seeds. 

124. It is very important to distinguish between the simple 
and the compound pistil, for when there are several in the 
same flower they often grow together, forming a single body 
with members more or less distinct. As the petals grow

together, forming a monopetalous corolla, so the pistils may 
combine into a compound pistil. The parts of such a pistil 
are conveniently called carpels. 

125. As to the extent of this union of the pistils, it is found 
in all possible degrees, always beginning at base and pro- 
ceeding upwards. For example, in Columbine (Fig. 209), 
the live carpels (pistils) are entirely distinct ; in Early Saxi- 
frage (Fig. 214), the two carpels are united at the base ; in 
Fink (Fig. 213), the two unite to the top of the ovary, leav- 
ing the styles distinct; so also in Flax (Fig. 212); in Even- 
ing Primrose, the four pistils cohere to the top of the style, 
leaving the stigmas distinct ; and finally, in the Lily, the 
three carpels are united throughout. (See Figs. 209-214.) 

126. We may know the number of carpels in a compound

pistil by the number of separate styles, or by the separate 
stigmas, or by the lobes of the stigma or ovary, or by the 
number of cells in the ovary, or (when only one cell) by the 
number of seed-rows. Thus the three-lobed stigma or ovary 
of the Lily indicates a triple pistil, also the three stigmas ot 
the Spring Beauty, and the three seed-rows in the Violet 
(See Fig. 229.)

simple, with one seed-row. 

127. But when the pistils remain separate and distinct we 
call each one a simple pistil. Thus in Columbine (Fig. 209) 
there are five simple pistils ; in Anemone (Fig. 207), and in 
Buttercups, many ; while in Cherry, Peach, Bean, Alchemilla, 
and Jeffersonia, there is just one simple pistil in each flower. 
Such a pistil is usually of an irregular form, with its style 
lateral (on one side), and only one seed or seed-row. (See Figs. 
215, 216.) 



126. Please tell us how you detect the number of carpels in the compound 
ovary of Spring Beauty ; of Lily ; of Violet.

TWO KINDS OF BUDS.

LESSON XIX. 

HOW THE LEAVES ARE FOLDED IN THE BUD 




^Estivation.— Fig. 217. Valvate calyx, as of Mallow. Fig. 218. Sepals of Holly- 
hock, — valvate-reduplieate. Fig. 219. Sepals of Clematis, — valvate-induplicate.

Fig. 222. Petals and sepals of Lily or Tulip. Fig. 223. Petals of Wall-flower,— 
convolute. Fig. 224. Petals of Pea,— vexillary. 

128. There is the leaf -hud, consisting of many scales and 
young leaves, folded up in such a manner as to occupy as 
little space as possible ; and the flcwer-hud, consisting of the 
organs of the flower in their early state, also closely packed. 
Now if you study the arrangement of the pieces composing 
the bud of either sort, you will be surprised and delighted 
with its variety and elegance. As each species of plant has 
the same invariable mode of folding in all its buds, this stud j 
well becomes a matter of science. 



Less. XIX. — What is the subject of this Lesson? 
V4S. Two kinds of buds ; please describe each. 



72 OBJECT LESSONS IN BOTANY. 



129. With a sharp knife let us make a cross-section (that 
is, a cut square across) of a flower-bud just ready to open : 
we may thus obrain some such view T s as are here drawn. 
For example, in Fig. 217, we have the valvate arrangement. 
Here the pieces composing the circle barely touch each other 
by the edges, as in the sepals of Mallows, petals of Lilac, 
valves of a seed-vessel. (See, also, Figs. 218, 219.) 

130. In the Phlox, Flax, Oleander, we find a twisted or 
contorted arrangement of the petals (Fig. 220), where each 
piece overlaps the next, all in one direction. 

131. The bud is said to be imbricated, when some of the 
pieces are wholly outside, covering by the two edges others 
which are wholly inside. But this may take place in various 
ways. See how it is in the petals of the Eglantine, or Apple 
(Fig. 221). Here two petals are outside, two inside, and one 
partly both. In the Tulip, one sepal is outside, one inside, 
and one partly both. And just so with its three petals 
(Fig. 222). 

132. The bud is convolute when each leaf wholly involves 
all that are within it, as do the petals of Magnolia and Wall- 
flower (Fig. 223) ; and it is vexillary in the Pea tribe, where 
only the outside petal, larger than the rest, infolds them all 
(Fig. 224). 

133. The plicate arrangement is found in monopetalous 
flowers, as in Thornapple, Potato, where the corolla is folded 
in a manner somewhat like a fan. 

129. How do we prepare a bud for examination ? What do you under- 
etand by a cross-section ? Define the valvate arrangement, with examples. 

130. What aestivation do we find in Flax, Phlox, &c. ? 

131. What is the imbricated aestivation? Describe it in the petals of 
Tulip ; Apple ; Eglantine. 

132. How are the petals arranged in the bud of Wall-flower ? 

133. How in the flower of Thornapple ? or Potato ? 



VERNATION. 



13-i. The pupil should make himself well acquainted with 
these seven modes of cestivation (so the botanists call it). 
Other modes are described in larger works. (Class Book of 
Botany, p. 79.) 

135. Also in the leaf-bud we find similar modes of leaf- 
folding (here called vernation, from the Latin vermis^ spring, 
as (Estivation is from cestivus, summer). The figures follow- 
ing represent cross-sections of various sorts of leaf-buds. In 
the bud of Sycamore the infolding scales are imbricate, but 
the young leaves within are somewhat plicate. 

136. In the leaf-bud of Cherry (Fig. 230) we find the con- 
volute vernation, similar to the cestivation of Wall-flower. 
The leaf-bud of Lilac (Fig. 231) gives us another form o\ 
imbricate.

its opposite leaf.

the bud of Balm-of-Gilead (Fig. 234) they are involute, or 
rolled inwards from both edges. This is best seen under a 
microscope of one lens, i. e., a single microscope. 

140. In the bud of Tulip tree (Fig. 225) each leaf is recti- 
nate^ being bent over forward and infolding all within it ; 
and in the Fern (Fig. 226) it is circinate, or coiled from the 
top downwards, like a watch-spring.

LESSON XX. 

HOW THE FLOWERS ARE ARRANGED ON THE PLANT. 

*41. We may now devote one or two lessons to the arrange 
ment and position of the flowers upon the plant, a subject to 
which botanists give the name of inflorescence. 




Fig. 235. Staphylea trifolia; a pendulous, paniculate cyme. 
Fig. 236. Catalpa ; a panicle. 

142. Every one has observed such facts as the follow 
mg, namely, that flowers are sometimes alone, and often li* 
clusters ; that they are sometimes raised on stalks, and some

142. What common facts in inflorescence does everybody notice? 



76 OBJECT LESSONS IN BOTANY. 



times sessile (or without stalks); and 'that they may arise 
from terminal buds, or from axillary. With the meaning of 
the words terminal and axillary you were made acquainted 
in Lesson IX. 

143. The stalk which supports the flower, or the cluster of 
flowers, we call peduncle. Now the peduncle may be either 
simple, bearing a single flower, or divided into branches and 
bearing a cluster of flowers. In the latter case, the branches 
or branchlets are called pedicels. 

14i. When the peduncle arises from terminal buds it 
seems like a continuation of the main stem, as in Foxglove, 
Horse-chestnut ; and when from axillary buds, it comes out 
from the side of the stem just above a leaf, as in the Cur- 
rant. Sometimes it arises from the root or some under- 
ground part of the stem, and then we generally call it a 
scape. Thus the flower-stalk of Tulip is a scape ; also of the 
Dodecatheon. 

145. The flower is said to be solitary, not only when alone 
on the plant, but also when alone in the axil of a leaf, as in 
Fuchsia, Morning-glory, Petunia. 

146. Among clustered flowers, you will often meet w T ith 
the following twelve varieties of inflorescence, which we 
must now try to represent and describe. We begin with the 
spike, such a cluster as we see in the Plantain, Mullen, &c. 
We may define it thus : A long peduncle (called rachis), 
having sessile flowers arranged along its sides. But before 
we go further with inflorescence, we must examine the tracts 
which accompany it. 

143. Please define peduncle ; also pedicel. 

144. When are the flowers terminal ? axillary ? Define scape. 

145. Why is the flower called solitary in Fuchsia, Petunia, &c. ?. 

146. Define a spike. Explain to us the rachis.

Bracts (&, £, b). Fig. 237. Cornus Canadensis, with an involucre of four colored 
biacts. Fig. 238. Hepatica triloba, with an involucre of three green bracts. Fig. 
239. Calla palustris, with a colored spathe of one bract, inclosing the spadix. 



147. Bracts are evidently of the same nature as leaves, 
differing only in their diminished size, and in their position 
on the flower-stalks, or near the flowers. They are some- 
times colored as brightly as flowers, as in Painted-cup, or in 
Balm. When several bracts are arranged in a whorl at the 
base of the cluster of flowers, an involucre is formed, such as 
we find in Carrot, and most of the Umbelworts (Fig. 244). 
In the Flowering Dogwood the large involucre is colored 
white. 

148. Next in resemblance to the spike is the spadix, an 
inflorescence seen in the Calla (Fig. 237), Golden-club (Fig. 
241), and Cat-tail. It may be defined as a thickened, club- 
shaped spike, often with a large bract (called spathe) at base, 
as in Jack-in- the-pulpit, or without a spathe, as in Fig. 241. 

147. What sort of leaves grow on the peduncles, if any ? Define bracts

149. An amenta called also catkin, is a more slender and 
delicate spike, filled with colored scales and flowers, and all 
falling together without separating, such as adorn the Birches 
(Fig. 242), Willows, and Poplars in early spring. The Hop 
also bears aments. 



LESSON XXI. 

THE INFLORESCENCE, CONTINUED. 

150. The flowers of the Black Cherry, Currant, Foxglove 
Locust, and Moth-mullen are in racemes. The raceme, then, 
is a rachis bearing its flowers on distinct, simple pedicels

151. Tlie corymb differs from the raceme in having the 
lower pedicels lengthened so as to elevate all the flowers to 
about the same level, as in the Yarrow or "Wild Thorn. 

152. The umbel appears in Milkweed, Onion, Ginseng, Szc. 
It consists of several pedicels of similar length, all arising 
from the same point at top of the peduncle. But in Car- 
away, Carrot, and most of the Umbelworts (Fig. 244), the 
umbels are compound, as if each of the pedicels had become

itself an umbel. These secondary 
umbels we call amhellets. At the 
hase of the umbel there is usually a 
whorl of bracts forming an involucre 
(a), and often also at the base of 
each umbellet (5), when we call it an 
involucel. 

153. The fine flowers of the Ca- 
talpa are in panicles (Fig. 235), also 
the flowers of Oats. We may describe 
a panicle as if a raceme should have 
its pedicels irregularly branched. 

154. A cluster resembling a pani- 
cle, but more compact, such as you 
see in Lilac, is called a thyrse. 

155. A head of flowers, such as we 
see in Clover or the Button-bush, 
hardly needs description. We might say that the head is a 
reduced umbel, having its flowers all sessile at the top of the 
peduncle. 

156. The great family of the Asterworts has all its flowers 
in heads, so dense and so nicely arranged as to be easily mis- 
taken for a single flower. But if you carefully examine such 
a head, say of an Aster, or especially of a Sunflower, you 
will see that it is composed of many little flowers or florets. 
The florets of the outer row are enlarged and open, so as to

CONCERNING THE FRUIT. 

161. The flower is of short duration. After a few hours 
or a few days of blooming beauty, it fades and disappears.

The stamens and petals have accomplished their work, and 
are dead. The sepals also, when colored like petals, are 
dead. But the pistil, especially the ovary, yet remains in its 
place, living and growing until the seeds which it contains 
are perfect. 

162. Thus the fruit is the ovary or pistils brought to per- 
fection. 

163. During the growth and ripening of the pistil, great 
and manifold changes occur, so that at last the fruit is very 
different in form, size, substance, and color. The little pistil 
in the flower of the Cherry must undergo a great alteration 
in becoming a plump Ox heart !

164. In the fruit we see the end and 
aim of plant-life accomplished, accord- 
ing to the wise and good design of the 
great Creator. While it serves to re- 
produce and keep alive the plants upon 
the earth, it also serves as food for ani- 
mals and for man. 

165. It is curious to observe how dif- Fig 266> Drupe _ a ripe

Appie, we eat the calyx which here 

adheres to the ovary, and in ripening was thickened and en- 
larged by the nutritious substance. In the Strawberry, we 
eat the enlarged, pulpy 
torus, which bears, all 
over its surface, the little 
dry, seed-like fruit. In 
Peach, the luscious mor-

the ovary itself; and in 
the Orange, it is the in-

Pea, Wheat, and most 
plants, the nourishing 
matter is laid up in the seeds, while the carpels ripen into 
a dry fruit.

Fruits that open we will call dehiscent fruits, and those 
which do not open, indehiscent. We will first study some oi 
the forms of indehiscent fruits, arranged as follows : 

167. First Division : Fruits indehiscent, one-seeded, dry ; 
namely, Achenium, Samara, Glans. 

166. Of what two parts docs the fruit consist ? What is a dehiscent fruit 1 
Indehiscent ? 



OF THE FRUIT 



87 



279 



Second Division: Fruits indehiscent, one-seeded, fleshy ; 
namely, Drupe, Tryma, Et^erio. 

Third Division : Fruits indehiscent, several-seeded ; name- 
ly, Berry, Pepo, Pome. 

168. The achenium is such a fruit as we find in Butter- 
cups, Anemone, Sage. Usually there are several produced 
together from one flower. We must not mistake them for 
seeds. They are pericarps, each inclosing one seed, as you 
see in the figures. The grain of Wheat or Corn (called cariop- 
sis) is much the same, but the one seed cannot be separated 
from the pericarp. 

169. The samara u mere- 
ly an achenium with a wing, 
as in Ash, Elm, Maple. The 
latter fruit is a double sa- 



mara. 

170. A glans (or nut) is 
such a fruit as Acorn, Chest- 
nut, Hazelnut, much like 
achenium, but larger, and 
seated in a cup or invo- 
lucre. 

171. A drupe is such a 
fleshy fruit as the Cherry 
or Peach. It is well called 
a stone-fruit. The stone in- 
closes the One Seed, and is larged view, showing the seeds lying in 

itself inclosed in a juicy %ffi S2m Fruit of Henbane,

172. Tryma is the name for such fruits as Walnut, Cocoa- 
nnt. Like the drupe, it lias a stony seed- shell, but its outer 
coat is rather woody than pulpy. 

173. Such fruit as the Raspberry or Blackberry we call 
etuerio. It consists of many little fleshy drupes growing fast 
together or to the torus. In the Blackberry they grow to 
the torus (Fig. 268). 

174. The berry is a thin-skinned, pulpy fruit, holding its 
several seeds loose in the pulp, as Currant, Grape (Fig. 261). 
The Orange, &c, is much like a berry, but on account of its 
thick rind has been called by another name (hesperidium). 

175. Pejpo is such a fruit as Squash, many-seeded, with a 
hard, crusty rind. 

176. Pome, the Apple, Pear, Haw, a fleshy fruit with sev- 
eral distinct cells. Here the fleshy calyx grows fast to the 
ovaries ; while in the Hip, or Rose-fruit, the fleshy calyx 
merely incloses the ovaries, as seen in Fig. 203. 



LESSON XXIII. 

FRUITS, CONTINUED. 

177. The dehiscent pericarp, — that is, those which open to 
discharge the seeds, — are generally dry fruits, known as pods. 
The various forms have the following names : Pyxis, Folli- 
cle, Legume, Silique, Capsule. 

168-176. The student will now please define and name the fruit of Butter- 
caps, Corn, Ash, Maple, Oak, Hazel, Plum, Walnut, Raspberry, Grape, 
Orange, Squash, Pear, Haw, and Rose. 

177. Please give the names of the dehiscent pericarps. 



FORMS OF FRUITS.

178. The pyxis is the most curious and singular of all pods. 

It opens crosswise by a lid, like a snuff-box. Fig. 284 is the 

likeness of the pyxis of Rheumatism-root, common in Ohio, 

It is formed of one carpel only. Fig. 282 is the pyxis of 

Henbane, formed of two carpels. So the pyxis 

of Poor-manVweather-glass (Anagallis, Fig. 

344.) is formed of several carpels.

Fig. 287. A jointed legume, or loment, — fruit of Desmodium. 

Fig. 288. A silicle, — fruit of Shepherd's-purse. 

179. Follicle is the name of such pods as those of Colum- 
bine (Fig. 208), Milkweed (Fig. 2S3), and of Dogbane (Fig. 
285). They are formed of a single carpel, and open length- 
wise, on one side only. It is easy to see the resemblance 
between the follicle and a leaf, the leaf being folded so as to 
bring its two margins together. (See Fig. 207.)

opening by two valves (Fig. 286). Such a pod is sometimes 
divided crosswise by joints (as in Fig. 287, Desmodium); we 
then call it a loment. 

181. Silique is a two-carpeled pod, such 
as we find in Mustard. It has two cells, 
separated by a thin partition, and two 
rows of seeds (Fig. 291). A short silique, or 
one not much longer than wide, such as 
we find in Pepper-grass or ShepherdVpurse 
(Fig. 288), is called a silicle. (See Fig. 290). 

182. Capsule (the word means casket). 

This name is applied to all 
other forms of dry, compound 
fruits, formed of several unit- 
ed carpels. In opening, they 
commonly split into several valves, as in Iris; 
or divide into several parts (carpels) like so 
many follicles, as in St. Johnswort ; or they 
open by small pores, as in Poppy.

183. We should not omit altogether to notice the aggre 
gated fruits, such as the Pine-cone (Fig. 300), Pine-apple, 
etc. These fruits are composed not merely of the pistil, but 
of the entire flower, or even of the whole inflorescence, bracts 
and all, grown thick, and consolidated into one fleshy mass. 
This is evidently the nature of the Pine-apple and of the 
Mulberry.

185. But there are some kinds of fruit almost or qi.ite des- 
titute of a pericarp, consisting of naked seeds. On the pre- 
ceding page is a figure (301) of the Canada Yew, a trailing 
shrub of New England and Canada. The fruit is a single 
naked black seed, seated in a fleshy, coralline-red cup. Tho 
cone (of Pine, Fir, &c.) is made up of thick woody bracts, each 
covering in their axils two or more winged seeds (Fig. 300). 



LESSON XXIV. 

CONCERNING THE SEEDS. 

186. Last and most important is the seed, the perfected 
ovule, containing the germ of a new plant like its parent 
plant. The seed consists of a kernel and its shell. Place a 
bean in w r ater, and soon its softened shell or skin is easily 
separated from the kernel. 

187. The shell of a seed may be of any color, as white, 
black, yellow, red, &c. ; may be polished and shining, or dull 
and rough; may be of any shape, as round, or oval, or egg- 
shaped ; may be winged, as in Catalpa, or may be clothed 
with long hairs, called coma. The silk of Silk-grass (Ascle- 
pias) is the coma of the seed, and cotton is the coma of 
Cotton seed. The seed of Poplar (cotton- wood) or Willow 
is also furnished with coma. 

185. What plants have no pericarps? Please describe a cone of Pine 
fruit of Yew. 

186. What is the seed, and what does it contain ? Of what two parts 
does it consist ? 

187. ^V^lat do you remember concerning the color and shape ? Describe 
the coma of a seed 



CONCERNING THE PAPPUS.

Fig. 310. Achenium of Wild Lettuce; with pappus raised on a beak 



188. The learner must distinguish between the coma of a 
seed and the pappus of a fruit. The down of Thistle or Dan- 
delion is pappus, for the little fruit on which it grows is not 
merely a seed, but a pericarp (achenium), also containing one 
seed. In a word, the seed may be fledged with a coma, but 
the fruit is fledged with a pappus, both intended as wings 
to bear away the seed to distant places. (See Class Book oi 
Botany, § 485.) 



188. AHiat is the distinction between coma and pappus?

189. As to the seed-kernel, 
it may concist of two parts, 
namely, the germ and albu- 
men, or it may be all germ. 

190. In the Bean (Fig. 311) 
l is all germ. A better name 
for the germ is embryo. JSTow 
in all seeds, the embryo is, in 
fact, a miniature plant, consist- 
ing of three parts, viz., radi- 
cle, plumule, cotyledons. In 

this Bean, V is the radicle, p radicle; p, the plumule

and become root. The plumule is the young bud destined 
to expand upwards and become stem and leaves. The cotyle- 
dons are two young leaves, thick and bulky, full of starchy 
matter to feed the embryo when it shall awake and begin to 
grow. 

192. In the Wheat-seed (Fig. 312) we find, besides the 
embryo, a white, mealy mass (a), well known when ground 
into flour. This mass is evidently intended to answer the 
same purpose as the starchy cotyledons of the Bean — to 
nourish the embryo. The radicle (>), the plumule (p\ the 
cotyledon (<?), and the albumen (a), are clearly shown. Fig. 
313 (seed of Four-o'clock) also shows albumen ; here the em- 
bryo is coiled into a ring around the albumen. Thus we see 
that the food of the young plantlet is laid up somewhere in 
every seed, either in the bulky cotyledons of the embryo 
itself, or in the albumen outside the embryo. 

193. We have, then, seeds albuminous, and seeds exalbu- 
minous ; seeds two-cotyledoned, and seeds one-cotyledoned. 



LESSON XXV. 

THE SEED BECOMING A PLANT. 

191. We have seen that the ripened seed is a miniature 
plant, living, but sleeping; packed and sealed up for trans- 
portation. It may continue to sleep, perhaps, for years, if

kept dry ; but if exposed to moisture, it soon 
awakes and commences its wonderful course of 
development. 

195. In the Spring of the year the melting snows 
or the warm rains supply the proper moisture to 
fie needs which have fallen to the ground, and 
they may be seen everywhere swelling, bursting 
and growing. The young botanist must not fail to 
watch their development. 

196. Beneath some Oak, for example, 
buried in the old leaves, we find acorns 
in all stages of growth, showing at one 
view all the steps in the process of ger- 
mination. Here is an acorn wif 
its shell softened and its kernel 
little swollen. We divide it lengt

198. J n the next stage of growth 
(Fig. 320) the two stalks of the cotyle- 
dons (s, petioles, Less. I.), make their 
appearance, and from between them, at 
the top of the rootlet, the plumule 
shoots forth, a little stem with a bud 
at the top, directing its course up- 
wards. The rootlet, meanwhile, has 
grown longer, entered the soil, and 
divided itself into branches and fibres 
all covered over with fine white hairs. 
These hairs, called fibrils, may be 
seen under a microscope, as in Fig. 
322, which represents the end of a F ^ 322 - The extreme end

199. Up to this stage, the growing rootlet and bud have 
drawn all their nourishment from the store of food laid up 
beforehand in the thick cotyledons for this very purpose ; but 
now the rootlet has reached the soil, and by means of its 
numerous fibrils, which are so many little mouths, it is begin- 
ning to draw its nourishment from the earth.

in the soil, while the bud has mounted higher, unfolding 
itself into stem and leaves, and spreading itself in the air and 
light. 

201. The young plant has now become independent of the 
seed, which will soon wither and perish. The cotyledons, in 
this case, are never able to throw off the shell, but perish

joints (called nodes and internodes) of the stem, its outer 
scales into leaves, and is itself continually renewed from 
within. Thus the ascending stem, or axis^ is always termi- 
nated by a bud.

203. Soon other buds appear. There is one in the axil of 
each leaf. So long as the terminal bud only is developed, 
the plant grows up a simple stem. But by the growth of 
these axillary buds, if they grow at all, branches are pro- 
duced ; and these branches, from their axillary buds, produce 
branchlets, and so on.

LESSON XXVI. 

LIFE OP THE PLANT, OR ITS BIOGRAPHY. 

204. The water which the plant imbibes by its roots be- 
comes sap in the stem, and circulates in every part as the 
blood circulates in the animal frame. The leaves, by their 
broad, thin forms, serve as lungs, to bring all the sap which 
passes through them into contact with the air and light. 

205. By this means the sap is changed into a nourishing 
food, fitted to sustain the growth of the plant in every part. 
Thus the leaves are designed, not only as an ornamental robe, 
but as organs of breathing and digestion. 

206. In the second stage of growth, when the plant depends 
no longer upon the seed for nourishment, it goes on increas- 
ing in stature and multiplying its leaves and branches. It 
now consists of three parts, namely, root, stem, and leaves. 
These are called the organs of vegetation. 

207. The third stage of plant-life is the period of flowering. 
Before this period, all its activity was devoted to its own 
nourishment and growth. Now it begins to live and act for 
the continuance of its own kind after it upon the earth, 
according to the Divine decree in Genesis, i., 11. Some of 
its buds undergo a striking change, and open each a flower 
instead of a leafy branch. 

208. A flower is therefore a leafy branch transformed (as

shown in the Class Book, p. 23), having its axis undeveloped 
its leaves in crowded circles, moulded into more delicate 
forms and tinned with brighter colors, not onlv to adorn the 
face of nature, but to prepare the way for fruit. 

209. The fourth stage of plant-life is the period of its fruit 
bearing. The flowers have gradually faded and disappeared 
but the pistil, having received the quickening pollen (see Class 
Book of Botany, p. 148), remains in its place, holds fast alJ 
the nourishing matter which continues to flow into it through 
the flower-stem, grows, and finally ripens into the perfected 
fruit and seed. 

210. The fifth and last stage in the biography of the plant 
is its hibernation (winters sleep), or its death. If the event 
of flowering and fruit-bearing occur within the first or second 
year of the life of the plant, it is generally followed by its 
speedy death. In all other cases it is followed by a state of 
needful repose, wherein it is commonly stripped of its leaves, 
and gives few, if any, indications of life, until awaked, with 
renewed vigor, in the following Spring. 

211. According to their different terms of life, we distin- 
guish plants as annuals, biennials, and perennials. An an- 
nual herb completes its whole history in one year. In the 
Spring it germinates ; in Summer it grows, blooms, bears 
fruit; and in Autumn its work and life are ended. The 
Mustard, Maize, and Morning-glory are such.

germinates, grows, and bears leaves only ; and in its second 
year it blossoms, bears fruit, and dies. Such are the Beet 
and Radish. 

213. A perennial plant survives several or many yearp. 
There are herbaceous perennials and woody perennials. The 
herbaceous perennials, or perennial herbs, are such as survive 
the winter only by their roots or their parts which grow 
underground. These in Spring send up leaves, flowers, and 
and often stems, all of which perish in Autumn, leaving only 
the parts underground alive as before. Such are the Hop, 
Asters, Violets. 

214. Woody perennials survive the winter by their stems 
as well as roots, and usually grow several years before flow- 
ering, and thence flower annually during their existence. 
Accoiding to their size, such plants are trees, shrubs, under- 
shrubs. A tree is^he largest among plants, having a perma- 
nent, woody stem, usually unbranched below, and dividing 
into branches above. The Oaks, Elms, and Pines are famil 
iar examples. 

215. A bhrub is smaller than a tree, usually growing in 
clusters from one underground mass of roots. The Lilacs, 
Roses, Alders, are shrubs. Small shrubs, about of our own 
stature, as the Currants, Brambles, we call bushes. Yery 
low shrubs, as the Blueberries, Box, &c, are undershrubs.

or bod j of the plant around 
which the brandies and 
other organs are arranged. 
As we have already no- 
ticed, the axis grows and 
extends in two directions, 
— upwards and downwards. 
The ascending part is the 
stem, the descending part 
is the root. The former 
loves and seeks the air and 
light, the latter the dark, 
damp bosom of the earth. 

217. The Root serves the 
twofold purpose of fixing 
the plant firmly in its place, 
and of imbibing the neces- 
sary food from the soil. 
The food when thus im- 
bibed is never in a solid

sists of certain earths, alkalies, and 
gases. (See Part II., Chap. 7, Class 
Book of Botany.) 

218. It is the nature of the root to 
divide itself into branches, and the only 
organs which properly belong to it are 
branches, fibres, and fibrils. It puts 
forth no buds nor leaves unless the 
plant be in some unnatural state. 

219. The roots of woody plants, es- 
pecially, are hranching roots. Year 
after year they multiply and extend in 
branches and branchlets beneath the

ground, in proportion to the growth of the branches and 
twigs of the stem above. The axis itself may not descend 
to any great depth, and after a few years may be found far 
exceeded in growth by its own branches which extend hori- 
zontally in a better soil. The greater the growth of the root? 
the more firm will be its hold upon the ground, and the great- 
er its capacity foi* drinking in liquid nourishment for the tree. 

220. The roots of herbaceous 
plants take a great variety of 
forms. Some are tuberous, some 
fibrous. The tuberous are such as 
consist of a large axis or body, witn . 
small branches ; as in the Beet, 
Ground-nut, Spring Beauty, and 
many other biennial plants. 

221. The fibrous are such as con- 
sist mostly of fibres, with scarcely 
any axis ; as in Buttercups, Grass- 
es. In such cases the axis ceased

226. It is the nature of the stem to produce buds, as it is oi 
the root to produce none. At first the stem is itself a bud, 
and as it grows it bears this bud always at the summit and 
produces a new bud in the axil of every new leaf.

the leaves severally come out are the nodes, and the portion 
of stem between, the internodes. In the bud the internodes 
are quite undeveloped, and the nodes close together ; but as 
it develops into a regular leaf-stem, the internodes grow, and 
the nodes with their respective leaves are separated.

stems. 

229. Several varieties of scale-stems must be distinguished ; 
as, bulb, corm, rhizome, creeper, tuber, &c. 

230 The Tulip, Hyacinth, Onion, Lily, have bulbs ; you 
see (Figs. 346, 347), they consist of roundish masses of thick 
scales with a small axis — in fact, an overgrown bud. The 
corm is like it in shape, but has a thick axis with thin scales 
or none. (Fig. 345.) 

231. The rhizome, or root-stock, is a fleshy, underground 
stem, often scaly and marked with scars, as you see in tho 
Bloodroot, Solomon's Seal (Figs. 348, 349).

232. The creeper is more slender, much branched, many- 
jointed and many-scaled, as seen in this figure of the Witch- 
grass. It sends out rootlets from its joints, and is very tena- 
cious of life, binding the soil into turf wherever it abounds. 

233. The tuber, such as grows on the underground stemy 
of the Potato-plant, is evidently a stem (not a root), for it al« 
ways produces buds.

234. Of the leaf-stem class we must describe three kinds, 
the trunk, caulis, and vine. Trunk is the name given to the 
stems of woody, erect plants, especially of trees. They are 
the representatives of loftiness and strength, in poetic phrase, 
lifting their summits to the skies and doing battle with the 
storm. There are, indeed, few objects in nature possessed of 
a truer grandeur than the White Pine's trunks of the North 
ern forests. 

235 Caulis, is the general name given by botanists to the 




Vines. Fig. 351. Passion-flower {Passiflora lutea), climbing by tendrils. Fig 
$52. Morning-glory, twining from left to right. Fig. 353. Hop, twining from righ 
to left.

stems of Kerbs. From this word come two adjectives much 
used and quite convenient, viz., caulescent and acaulescent / 
the former denoting the presence of stems above-ground, the 
latter of only underground stems. Thus the Buttercup is 
caulescent, while the Pitcher-plant is acaulescent ; the Garden 
Violet or Pansy is caulescent, while the wild Blue Violet is 
acaulescent. 

236. Vine, as every one knows, denotes a slender stem, too 
weak to stand alone, and supporting itself by the aid of other 
plants or objects. Some vines are woody, some herbaceous; 
The Hop twines itself around its supporter, turning from 
right to left, as in Fig. 353. The Morning-glory, also, but 
it turns from left to right (Fig. 352). Thirdly, the Grape 
and Passion-flower (Fig. 351) climb by special organs, the 
tendrils, of wonderful adaptation, showing their Maker's de- 
sign more truly than if by an audible voice.

LESSON XXIX. 

PLANTS TO BE ARRANGED IN CLASSES. 

PLAXT may be studied by 
itself, as an individual, separate 
from other plants or objects: 
or it mav be considered in its re- 
lations to other plants, as consti- 
tuting a part of a system. In 
this latter view we discover one 
vast design embracing the innu- 
merable millions of plants as one 
kingdom, leading us to adore the 
wisdom and goodness of him 
who planned and created the 
world. For we see that he has 
not only made each plant with 
so much loveliness and perfec- 
tion in itself, but has assigned 
to each its proper rank in the 
/ system, and endowed it with just 

that nature, habit, and style of beauty, which adapts It to 

that rank. 

238. To study plants as constituting a system, as we now 

propose to do, is useful in two ways : first, it gives us a 

larger and truer conception of the Vegetable Kingdom ; and 

237. What two modes of studying the plant are mentioned ? In the sec 
ond mode what discovery is made ? 

238. In the systematic study of plants what two other advantages?

Clover 



114 OBJECT LESSONS IN BOTANY. 



secondly, it teaches us bow to recognize by name the plants 
with which we meet, so as to avail ourselves of all that has 
been recorded concerning the same by botanists before us. 

239. Suppose the pupil, in his study, has dropped a single 
Flax-seed on a lock of cotton floating in water in a bulb- 
glass. It grows, filling the clear water with its silvery radi- 
cles, while its stem shoots upwards covered with leaves and 
finally blooming with flowers. This is an individual plant. 
He studies its organs, colors, portrait, and carefully writes its 
history. 

240. Meanwhile, other Flax-seeds, by thousands, have been 
sown in the fields, and from each, also, a plant has arisen. 
The student finds them in flower, tinging all the plain in 
ocean blue. Now, shall he, as a botanist, repeat his study 
over each of all these millions ? Certainly not. lie finds 
himself already acquainted with them, for each bears an ex- 
act resemblance to that which he has already described. His 
knowledge of one individual Flax-plant, therefore, avails him 
for each and all the myriads of Flax-plants growing every- 
where. 

241. In this manner we obtain the idea of a Species. Thus, 
a species of plants consists of many individuals of the same 
kind, having descended from a common stock, and resem- 
bling each other and their common parent in every feature. 

242. The common Blue Flax, of which linen is made, is a 
species / the wild Yellow Flax is another; and the Purple 
Flax of the gardens is another. The White Clover is a spe- 

239. Can you give us an idea of an individual plant ? 

240. Having studied one individual Flax-plant, why do we not need to 
study the others ?

242. Please illustrate your idea of a species. 



THE NATURAL SYSTEM. 115 



cies with its progeny of millions of plants ; the Red Clover is 
another ; the Yellow Clover another ; the Buffalo Clover 
another. In like manner all the plants of the globe are 
grouped into species, and this is the first step in classification. 

243, The second step carries us to the genus, which we 
may thus define : A Genus is an assemblage of species which 
are much alike ; especially in their flowers and fruit. Thus, 
Flax is a genus made up of the several species mentioned 
above, and other similar species. Clover is a genus com- 
posed of 150 species, some of which we have just mentioned. 
Every one notices the resemblance between White Clover, 
Red Clover, &c. Pine is a genus, embracing as species 
White Pine, Yellow Pine, Pitch Pine, Long leaved Pine, and 
many others. 

244. Individuals of the same species may differ somewhat 
amono; themselves, and these differences constitute varieties. 
Thus Apple-trees differ in their fruit, and there are hundreds 
of varieties although only one species. Roses differ in their 
form, color, and fragrance of their flowers, forming many va- 
rieties under each species. Probably no two plants of any 
species were ever exactly alike. Sameness, or monotony, is 
not a characteristic of Nature.

ences, botanists have formed a system called the Natural Sys- 
tem. Let us now briefly notice this system of classification. 

246. We have already stated that the plants of the globe 
are all created in species, and that this is the first step in 
classification. Then, in the second place, the species are 
grouped into genera. Now the number of species of plants 
already known is about 100,000, and the genera 20,000. 

247. The third step in our system carries us forward to the 
Natural 0\v krs. These are made up of genera. As we as- 
sociate similar species to form a genus, so we associate 
similar genera to form the natural orders. The number of 
orders described in the Natural System is about three hun- 
dred. For example, the natural order Crucifirae, or the 
Crucifers, embraces such genera as Mustard, Cress, Cabbage, 
Turnip, Radish, Wall-flower, which every one sees to bear 
resemblance to each other in many respects. 

248. How then shall we define a natural order? It is a 
group of similar genera ; or, a group of genera closely re- 
lated to each other. Therefore, individuals form species; 
species form genera ; genera form orders. But how shall we 
classify these three hundred orders ? 

249. Suppose we take an excursion into the mountains. 
We walk beneath the forest trees, and among the shrubs. 
W^e tread upon the lesser herbs, the matted grasses, and the 
mosses and lichens which cover the rocks. Everywhere we 
see plants, and behold the domain of the vegetable kingdom. 

245. What is the subject of this Lesson XXX. ? 

246, 247. What is the first step in classification ? the second ? the third ? 
What number of species known in all the vegetable world ? What numbei 
of genera ? of orders ? (Ans. 303.) 

248. Define a natural order. Please review these three steps 

249. Show how we may divide the vegetable kingdom. 



THE NATURAL SYSTEM. 



117 



Now riewing this as one grand whole, we want to divide it 
into two subkingdoms. How shall we do it ? 

250. Every attentive observer has noticed that some of 
these plants produce no flowers ; as, e. g., the Ferns and 
Mosses. Let us then take all such plants and consider them 
as forming one sub-kingdom, viz., the Flowerless Plants 
All other plants will of course constitute the other sub -king 
dom, viz., the Flowering Plants. Botanists call the latter 
the Phsenogamia, and the former, the Ciyptogamia (Greek 
words of the same import). 

251. Now these two sub-kingdoms have other 
distinctions besides flowering and not-flowering. 
See the fruit-clots growing on the back of Fern 
leaves. The microscope shows them to be clusters 
of hollow cases, and each case tilled with a fine 
'yellow dust. But this dust is not seeds, with 
embryo, radicle, &c. (Less. 24), but little sacs, 
containing a fluid, similar to the pollen grains 
(Less. 15). AYe call them Spores. See, also, the 
Mushrooms having no leaves, and the Lichens

often, also, without stems. Hence we may say of the Cryp- 
togams that they are not only jlowerless, but seedless, and 
often leafless and stemless. 

252. We wall now dismiss the Cryptogams for the present 
and consider the Flowering Plants (Phsenogams), as one sub 
kingdom; — how shall this be divided? Every one notices a 
striking difference between plants with parallel-veined leaves 
and those with net- vein eel leaves. The former have their 
flowers three-parted, w T hile the latter have their fhywers two, 
four, or five-parted, &c, — the former have seeds one-lobed 
(monocotyledoned, Less. 15), the latter, two-lobed (dicotyle- 
doned, Less. 15). Let us, then, divide the Phsenogamia into 
two provinces ; as Nature lias already done. 





Fig. 359. Cross-section of an exogenous stem (Elm), of two years growth: 1, the 
pith ; 2, 3, two layers of wood ; 4, the bark. Fig. 360. Cross-section of an endoge- 
nous stem (Corn), showing no distinction of layers. 

253. We may call these two provinces severally, the Exo- 
gens and the Endogens : — two Greek words denoting outside 
growers, inside-growers, referring to their modes of growth. 

254. Now, taking such an Exogen as the Apple-tree, and 
Luch an Endogen as the Indian Corn, we may distinguish 
them thus : The Exogen has its wood, if any, arranged in con- 
centric rings, or layers, as seen in Fig. 360 ; — the outer **ing 



252. Show how the Flowering Plants are divided. 253. Please give t he

being the youngest ; the leaves net-veined; the flowers sel 
dom (or never completely) three-parted ; and the seeds two 
lobed. On the contrary : 

255. The Endogen has its wood, if any, confused, the inner 
portions being the newest; — its leaves parallel-veined ;- -its 
flowers three-parted ; and its seeds or.e-lobed. 



LESSON XXXI. 

MORE ABOUT THE NATURAL SYSTEM. 

256. Thus Exogens and Endogens are so clearly defined 
that you may know them as far off as you can see them. 
The next step in the analysis is, to subdivide each of these 
provinces. First, as to the Exogens : We know that they 
generally have pistils in their flowers, with the young seeds 
(ovules) inclosed in their ovaries. But there are exceptions 
to this rule. The Pines, Yews, &c, have no pistils at all, or, 
at least, no stigmas, and produce naked seeds, not inclosed in 
seed-vessels. Hence, we have two classes of Exogens : the 
naked-seeded and the vessel-seeded. The botanists call the lat- 
ter the Angiosperms (Greek, angios, a vessel ; sperma, seed) ; 
and the former, the Gymnosperms (Greek, gyrnnos, naked). 

257. Secondly, the Endogens: here consider the peculiar 
forms and flowers of the Grasses. Their flowers are all en- 
veloped in green, alternate scales, called glumes, instead of 

254 Is the Lily an Exogen or Endogen ? The Buttercup ? The Maple, &c. ?

257. Show the subdivision of the Endogens. What of the Petaliferre !

120 OBJECT LESSONS IN BOTANY. 



the circles of petals common in other flowers. Hence we 
have a class of Glume-plants and of Glumeless-plants, or, as 
the botanists say, Glumiferje and Pktaliferje. Thus we 
divide all the Flowering Plants into four Classes, viz.: 

1. Angiosperms / Exogens bearing stigmas and seed-vessels. 

2. Gymnosperms / Exogens with no stigmas, and with naked 
geeds, as the Pines, Firs, Larches, Cedars, Cypresses,Yews, &c. 

3. Petaliferce / Endogens with no glumes and ordinary 
flowers. 

4. Glumiferce / Endogens with glumes instead of petals, as 
the Grasses, Sedges, Grains. 

258. Again, each of these Classes are to be subdivided into 
Cohorts, as follows : the Angiosperms are divided (not very 
naturally) into three cohorts, viz. : 

1. The Dialypetalce, or Polypetalous Exogens, having flow- 
ers with the petals distinct and separate, as in the Buttercup, 
Rose, Mustard. 

2. The Gamopetalce, having flowers with the petals united 
into one piece, as in the Phlox, Morning-glory, Foxglove. 

3. The Apeialm, having flowers without petals, either 
naked, or with only one circle of floral envelopes (which must 
then be considered as sepals, whatever be the color) ; as Gin- 
ger-root (Asarum), Poke (Phytolacca), and Pig-weed (CAeno- 
podium). 

4. Next, the Gymnosperms are regarded as forming one 
cohort, called the Conoids, having the fruit usually in cones. 
(Less. XXIIL) 

258 After tlie classes, what is tlie next step in analysis? How are tie 
Angiosperms subdivided? Please define tlie Polypetalous Exogens; the 
Oaniopetalous; the Apetalous. What cohort do the Gymnosperms form? 
Why ? What two cohorts do the Petaliferous Endogens form ? Define the 
fifth cohort. Define the sixth cohort. What cohort do the Glumiferoup 
Endogens constitute? 



THE NATURAL SYSTEM. 121 



The Endogenous Petaliferse are divided into two cohorts, viz. ; 
5 The Spadiciflorce, having the flowers on a spadix, as in 
the Egyptian Calla and Jack-in-the-pulpit. 

6. The Floridice, having the flowers separate, not on* a 
spadix, as in Tulip, Gladiolus. 

7. The Class Glamiferse constitutes the seventh cohort, 
ander the name Graminoids, i. e., the Grass-like plants. 

Six other cohorts are formed from the flowerless plants, 
but we cannot notice them in this work. 

259. Lastly, the cohorts are themselves divided into, or 
composed of, the Natural Orders, w r hich we defined in Les-

LESSON XXXII. 

OF THE ANALYSIS OF PLANTS. 

263. To study any subject by the separate examination of 
the parts of which it is composed, is a process called analysis. 
For example, in Grammar, we analyze a sentence when wo 
point out and separately consider the subject, predicate, 

?62. Of Table III. 263. What is the general meaning of analysis ? Illustrate 



BOTANICAL ANALYSIS. 123 



object, &c, In Chemistry, we analyze water when we sep- 
arate its two elements, oxygen and hydrogen, and examine 
each by itself. 

264. In Botany, however, we use the word analysis in a 
wider sense. It implies not only the separate study of each 
particular organ composing the plant, but doing all this in 
connection with certain tables, in order to determine its name 
and history. 

265 This kind of analysis is the constant and delightful pur- 
suit of the active botanist. Without it, the study of books loses 
half its pleasure and usefulness. The student can acquire a 
better knowledge of a species by the study of a living specimen, 
than by memorizing the longest description found in books. 

266. During the flowering months, he will often meet with 
species in blossom which are yet unknown to him. If he is 
duly interested in his study, he will not fail to seize and 
analyze each new specimen, and even extend his walk in 
search of more. In this manner, he may in a few seasons 
become acquainted with every species in his locality. 

267. But we do not expect that all this will be accomplished 
by our young friends while using as their only text-book this 
little work. We only aim now to furnish them with the 
means of making &fair begijining, so that they may be able, 
in future seasons, to advance rapidly with the " Class Book," 
or other works of that rank. 

268. In the following pages we present the pupil with 
numerous tables, designed to conduct our inquiries in every 
process of botanical analysis; also accompanied by a plain, 
miniature Flora, or a partial description of all the flowering 
plants in the United States. 

264. What is its signification in botany ? 



124 OBJECT LESSONS IN BOTANY 



269. Specimens gathered for analysis should have flowere 
in full bloom, full-grown leaves, and also, if possible, the 
mature fruit. If it be an herb, it is well to have the whole 
of it as the root and lower leaves often afford characters by 
which the species is known. Suppose you now have good 
specimens of some one unknowm plant, gathered for analysis, 
—how will you proceed with them ? 

270. We first examine the several parts of the plant, begin- 
ning with the root and ending with the pistil or ovary, deter- 
mining the character of each according to the definitions 
given in the former lessons. After this, w 7 e refer to the table 
commencing on page 121, entitled, "Review of the Natural 
System," and read, compare, and decide according to the 
directions contained in Lesson XXXIIL, in order to determine 
the Natural Order to which the specimen belongs. Having 
determined the Order, we next turn to that Order, and deter- 
mine the Genus and Species by means of other similar tables. 

271. In examining the specimen, previous to the use of the 
tables, the first inquiries may be somew T hat as follows : 

As to the plant — whether it be an herb, shrub, or tree. 

As to the root — whether tuberous, fibrous, or fibro- tuberous. 

As to the stem — whether a scale-stem or leaf-stem ; bul- 
bous, rhizome, or erect, &c. 

As to the leaves — whether alternate or opposite; parallel- 
veined or net- veined ; whether the figure be ovate, lanceo- 
late, oblong, &c. 

269. What kinds of specimens are to be preferred for analysis ? 

270. Please state the first thing to be done with them. After you hav 
found the Order, what then ? 

271. What special care should be taken? As to character, what do we 
inquire concerning plants? What concerning the root? the stem? the 
leaves ? the stipules ? What concerning the flowers ? the calyx ? the corol 
la ? stamens ? What concerning the pistil or fruit ? 



CTSE OF THE ANALYTICAL TABLES. 125 



As to stipules — whether present or absent. 

As to the flowers — whether symmetrical or unsymmetrical ; 
regular or irregular; whether the calyx be free or adherent ; 
the petals, whether distinct or united; the stamens, whether 
hypogynous or perigynous, whether opposite to the petals or 
alternate with them. 

As to the pistil and fruit, — whether the carpels be more 
than one, and whether distinct or united. (See Lesson 

xvni.) 



LESSON XXXIII. 

HOW TO ANALYZE A PLANT BY THE TABLES. 

272. Our readers are already informed that the Flora 
which accompanies these instructions is not intended to 
make them acquainted with the plants of the country, but 
simply to teach the pupil how to analyze. Hence they will 
not expect to find in it any thing like a full account of all 
our flora, but a few plain exercises by which they may trace 
every flowering plant in the country to its Natural Order, 
about one in every two to its Genus, and about one in every 
live to its Species. In conducting an exercise in this Flora 
with a class of pupils who have well studied the former part 
of the work, some method like the following would be inter- 
esting and profitable. 

273. Suppose the class present, and each furnished with a spe- 
cimen of some one unknown species, both in flower and fruit. 

Teacher. Are you all ready? Turn to the Flora and let us find out to- 
gether the family relations and the names of this fine plant. We will 
commence at the "Analysis of the Natural Orders" (page 132), and read 
the first pair of lines, which we will call a couplet.

John {reads). "Plants bearing flowers (Phsenogamia). 

"Plants not bearing flowers (Cryptogamia)." 

Teacher. To which of these sub-kingdoms does your specimen belong \ 

John. To the flowering plants, for it has both flowers and fruit 

Teacher. Now tell us to which couplet we shall next pass. 

John. To the second. 

Teacher. Very well. Edward, you may read and determine the second 
couplet in the same manner. 

Edward. "Leaves net- veined. Flowers never completely three-parted. 

"Leaves parallel-veined (rarely net- veined). Flowers three-parted." 
This specimen seems to answer to the first line, having net-veined leaves 
and five-parted flowers. It is, then, an Exogen. Pass to No. 3. 

Teacher. Now let it pass along, and if a wrong decision is made, let the 
observer signify it by raising his hand. 

Sarah. " Stigmas present. Seeds inclosed in seed-vessels. 

" Stigmas none. Seeds naked." These flowers have pistils and stig- 
mas. I think it is an Angiosperm. Pass to No. 5. 

Eliza. " Corolla with distinct petals. 

" Corolla with united petals. 

" Corolla none ; sepals sometimes none." My specimen has five distinct 
petals, and five sepals. It is therefore Polypetalous. Pass over to A. 

Jane. "Herbs. 

" Shrubs, trees, or undershrubs." This plant is an herb. Pass on to 
No. 2. 

Mary. " Leaves alternate or all radical. 

"Leaves opposite, on the stem." The leaves of the stem are alternate, 
but many are radical. Pass to No. 15. 

Louisa. " Flowers regular or nearly so. Fruit never a legume. 

"Flowers irregular," &c. I do not remember the legume. (Several 
hands are raised.) 

Teacher. Edward will define a legume. 

Edward. A legume, sir, is a fruit like a pea-pod. 

Teacher. Can Mary improve this definition? 

Mary. The legume is a simple, or one-carpeled fruit, with two valves 
and one cell. 

Louisa. But this plant has regular flowers, in any case. See No. 17. 

Nancy. " Stamens numerous." &c. I count more than twenty stamens 
here. Turn to No. 21.

Lvcy. "Stamens on the torus," &c. I think they are on the torus, and 
not on (he calyx. Next to No. 22. 

Emily. "Pistils few or many, distinct (at least as to the styles). 

"Pistils (styles, also, if any), completely united." I see many litt 1 e 
green pistils, quite distinct, in the centre of the flower. Go to No. 23. 

Caroline. "Petals rive or more, deciduous. Leaves not peltate," &c 
This flower has five petals, but I do not know whether they are deciduous 
or not. 

Teacher. Will some of you relieve Caroline's doubts? 

Emily, I think they are deciduous, for they have already fallen off from 
several of my flowers. 

Teacher. True. Then what is Caroline's decision? 

Caroline. I suppose, then, that the plant belongs to the "Order of the 
Crowfoots," which is the first natural order. 

Teacher. Well done. This brings us to the order of which our plant 
seems to be a member. Let us now turn to that order and learn the 
genus of the plant. But before we look into the " Analysis of the Gen- 
era," we should carefully compare our plant with the characters of the 
order, so that we may be sure that we have not erred in our conclusion. 
John will read aloud these characters, and the class will consider whether 
their specimens answer to each. 

John (reads). "Herbs, rarely shrubs, with a colorless, acrid juice" (&c., 
to the end). 

Teacher. Since we are now confident that we have a plant belonging 
to the order of the Crowfoots, let us commence the "Analysis of tlm 
Genera." Edward, the first couplet. 

Edward. " Sepals four, valvate in the bud. Achenia tailed. 

"Sepals imbricate in the bud." The sepals are imbricate. No. 2. 

Sarah. " Ovaries one-seeded, achenia in fruit. 

"Ovaries with two or more seeds." I find one seed in each ovary,— 
indeed, the ovary is itself like a little seed. Pass to No. 3. 

Eliza (after reading the couplet). The greenish sepals are quite diffc r 
snt from the yellow petals. Go to the triplet marked d. 

Jane (after reading the three lines). As this plant has leaves on the 
stem, and a little scale with honey at the base of each petal, I must pro 
nounce it a Crowfoot, genus No. 4. 

Teacher. We now turn to that genus (page 147), and read its character 
for the sake of confirmation and a better knowledge.

Mary (reads the character of the genus Ranunculus aloud). 

Teacher. We are now ready for the analysis of the species. Mary is next. 

Mary, u Petals yellow. Seeds (carpels) rough with prickles. Flowern 
small. South 

44 Petals yellow, seeds smooth and even 

u Petals white (claws yellow). Seeds wrinkled crosswise." This spe 
tfimen has smooth seeds and yellow petals. Pass to a. 

Louisa. " Leaves more or less divided," &c. This second line cf th* 
triplet describes the plant. Pass on to b. 

Nancy. M Root leaves neither divided nor cleft, merely crenate. 

"Lower leaves three-cleft, but not divided to the base. 

u Leaves all ternately divided and much cleft." Pask to c. 

Lucy. " Sepals reflexed in flower. Plants erect. 

"Sepals spreading in flower, shorter than the petals." The sepals arc 
reflexed. Read Nos. 14, 15. 

Emily, after reading both descriptions, finally concludes that she holds 
in her haud a specimen of the Bulbous Crowfoot, or Ranunculus bulbosus. 
in which conclusion all concur. 



LESSON XXXLV 

VARIOUS SUGGESTIONS AND CAUTIONS. 

274. The work of analysis is often attended with ditiicul 
ties which severely try the skill and perseverance of the 
young botanist. So it often is in the study of Algebra, or ol 
Logic; indeed, in nearly every valuable branch of learning 
His decisions may be wrong through a want of a thorough 
acquaintance with botanical terms, or through his ignorance 
of the real characters of his specimens. Of course his success 
will always be in proportion to the accuracy of his knowl 
edge, — here, as well as in all other pursuits. 

274. Mention two sources of error in the analysis of plants 



DIFFICULTIES IN ANALYSIS. 129 



275. But the minuteness of the organs or parts to oe 
studied is often discouraging even to the accurate student, 
much more to the careless one. To overcome this, skill in 
dissection and a dauntless courage in observation are indis 
pensable. Moreover, there is often much ambiguity in the 
nature of the subject. For example, whether the Geraniums 
are herbs or shrubs; whether the flowers of Petunia are reg- 
ular or irregular; whether the Pear leaf is ovate or oval, 
&e. Experience will at length diminish this difficulty. 

276. The exact limits between the classes, the cohorts, &c, 
are not always easily defined. For example, is Trillium an 
Exogen or an Endogen? Its netted leaves indicate the for- 
mer, but its flowers being three-parted throughout, and its 
seeds with one cotyledon, prove it to be an Endogen, Again, 
is Spring Beauty an Exogen or an Endogen? Its leaves 
seem, at flrst, parallel-veined, but as its flowers are five-parted 
it is an Exogen. 

277. Angiosperms will be readily distinguished from Gym- 
nosperms, if we remember that almost all the latter are ever- 
green trees, like the Pines, Cedars, Larches, &c. 

278. The industrious student w T ill very soon find himself 
so well acquainted with the different characters of the cohorts 
that he will in analysis refer his plant at once to its right 
cohort, without consulting the previous parts of the table. 
This is desirable; and a thorough acquaintance with the

THE FLORA: 



OR, 

ELECTIONS FROM THE NATIVE AND CULTIVATED PLANTS 
OP THE UNITED STATES. 

Designed as first exercises in Analytical Botany. 



Explanations.— The Tables in this work are designed to be complete, that is, each Ordinal 
Table includes all the genera belonging to that order known within the limits of the Flora (1 e., the 
States east of the Rocky Mountains); and each Generic Table includes, in like manner, all its 
known species. The numbers annexed to the genera in the Ordinal Tables, refer to the descrip- 
tions immediately following. If no number be annexed, the pupil will understand that that genus 
is not further noticed. 



COHORT I. 

THE FOLYPETALOUS EXOGENS. 

Iksential Character. — Flowering Plants (Ph^enogamia), 
with their stems growing by additions to their outside in 
layers (Exogens), their seeds inclosed in a seed-vessel or peri- 
carp (Angiosperms), their flowers with a double perianth and 
their petals distinct (Polypetaljs). (But to this last condition 
there are many exceptions.) 

Order I. RANUNCULACE^E. The Crowfoots 

Herbs, rarely shrubs, with a colorless, acrid juice, with 

leaves mostly alternate and mnch divided, without stipules; 

upals 3-15, deciduous, distinct, and colored when apetalous; 

vetals 3-15, distinct, often deformed or contracted or wanting; 

itamem oo, distinct, hypogynous ; 

pistils en (rarely 1 or few), distinct, becoming in 

fruit either achenia, follicles, or berries.

Order LXX.— COMPOSITE. Asterworts. 

An immense family of herbs or shrubby plants, with compound flowers, 
that is, the flowers {or florets) collected into close heads upon a common 
receptacle, and surrounded by an involucre of many bracts (called scales), 
with 5 stamens which have their anthers united into a tube around the 
Btyle, with the calyx tube closely adhering to the 1 -celled ovary (an ache- 
nium in fruit), and the calyx limb crowning the ovary in the form of a 
fappus consisting of scales, awns, bristles, or hairs, or else entirely want- 
ing; the corolla consisting of 5 united petals, either strap-shaped (ligulate 
or tubular, and the style 2-cleft at the top. 

In this Order the pupil wiH remember that the heads are called radiate, 
vhen the outer florets only have rays or are ligulate (see Fig. 498) ; radi-

ant, when all the florets are ligulate (Fig. 504) ; discoid, when all the florets 
are tubular, there being no rays (Fig. 509). The receptacle is the broad 
top of the stalk on which the florets sit (Fig. 499). It is chaff y when there 
are scales or bracts growing among the florets, and naked when none. 

The tubular florets constitute the disk, and the ligulate, if any, the ray ; 
the disk is generally yellow, while the ray is about as often cyanic (that is, 
blue, red, white, or any color except yellow) as yellow.
