THIS book is intended for the use of beginners, and for classes in the common and higher schools, — in which the elements of Botany, one of the most generally interesting of the Natural Sciences, surely ought to be taught, and to be taught correctly, as far as the instruction proceeds. While these Lessons are made as plain and simple as they well can be, all the subjects treated of have been carried far enough to make the book a genuine Grammar of Botany and Vegetable Physiology, and a sufficient introduction to those works in which the plants of a country — especially of our own — are described. Accordingly, as respects the principles of Botany (including Vege- table Physiology), this work is complete in itself, as a school-book for younger classes, and even for the students of our higher seminaries. For it comprises a pretty full account of the structure, organs, growth, and reproduction of plants, and of their important uses in the scheme of creation, — subjects which certainly ought to be as generally understood by all educated people as the elements of Natural Philosophy or Astron- omy are ; and which are quite as easy to be learned. The book is also intended to serve as an introduction to the author's Manual of the Botany of the Northern United States (or to any similar work describing the plants of other districts), and to be to it what a grammar and a dictionary are to a Classical author. It consequently con- tains many terms and details which there is no necessity for young stu- dents perfectly to understand in the first instance, and still less to commit to memory, but which they will need to refer to as occasions arise, when they come to analyze flowers, and ascertain the names of our wild plants. To make the book complete in this respect, a full Glossary, or Diction- ary of Terms used in describing Plants, is added to the volume. This con- tains very many words which are not used in the Manual of Botany; but as they occur in common botanical works, it was thought best to in- troduce and explain them. All the words in the Glossary which seemed to require it are accented. IV PREFACE. It is by no means indispensable for students to go through the volume before commencing with the analysis of plants. When the proper season for botanizing arrives, and when the first twelve Lessons have been gone over, they may take up Lesson XXVIII. and the following ones, and pro- ceed to study the various wild plants they find in blossom, in the manner illustrated in Lesson XXX., &c., — referring to the Glossary, and thence to the pages of the Lessons, as directed, for explanations of the various distinctions and terms they meet with. Their first essays will necessarily be rather tedious, if not difficult ; but each successful attempt smooths the way for the next, and soon these technical terms and distinctions will become nearly as familiar as those of ordinary language. Students who, having mastered this elementary work, wish to extend their acquaintance with Vegetable Anatomy and Physiology, and to con- sider higher questions about the structure and classification of plants, will be prepared to take up the author's Botanical Text-Book, an Introduction to Structural Botany, or other more detailed treatises. No care and expense have been spared upon the illustrations of this volume; which, with one or two exceptions, are all original. They were drawn from nature by Mr. Sprague, the most accurate of living botanical artists, and have been as freely introduced as the size to which it was needful to restrict the volume would warrant. To append a set of questions to the foot of each page, although not un- usual in school-books, seems like a reflection upon the competency or the faithfulness of teachers, who surely ought to have mastered the lesson be- fore they undertake to teach it; nor ought facilities to be afforded for teaching, any more than learning, lessons by rote. A full analysis of the contents of the Lessons, however, is very convenient and advantageous. Such an Analysis is here given, in place of the ordinary table of con- tents. This will direct the teacher and the learner at once to the leading ideas and important points of each Lesson, and serve as a basis to ground proper questions on, if such should be needed. ASA GRAY.

THE subjects of Natural History are, the earth itself and the beings that live upon it. 2. The Inorganic World, or Mineral Kingdom, 'The earth itself, with; the air that surrounds it, and all things naturally belonging to them which are destitute of life, make up the mineral kingdom, or in- organic world. These are called inorganic, or unorganized, because they are not composed of organs, that is, of parts which answer to one another, and make up a whole, such as is a horse, a bird, or a plant. They were formed, but they did not grow, nor proceed from previous bodies like themselves, nor have they the power of pro- ducing other similar bodies, that is, of reproducing their kind. On the other hand, the various living things, or those which have pos- sessed life, compose 3. The Organic World, — the world of organized beings. These consist of organs ; of parts which go to make up an individual, a being. And each individual owes its existence to a preceding one like itself, that is, to a parent. It was not merely formed, but produced. At first small and imperfect, it grows and develops by powers of its own ; it attains maturity, becomes old, and finally dies. It was formed of inorganic or mineral matter, that is, of earth and air, indeed ; but only of this matter under the influence of life : and after life departs, sooner or later, it is decomposed into earth and air again. 1 BOTANY, WHAT IT RELATES TO. [LESSON 1. 4.) The organic world consists of two kinds of beings; namely, 1. Plants or Vegetables, which make up what is called the Vegetable Kingdom ; and, 2. Animals, which compose the Animal Kingdom. ?>. The Differences between Plants and Animals seem at first sight so obvious and so great, that it would appear more natural to inquire how they resemble rather than how they differ from each other. What likeness does the cow bear to the grass it feeds upon ? The one moves freely from place to place, in obedience to its own will, as its wants or convenience require : the other is fixed to the spot of earth where it grew, manifests no will, and makes no movements that are apparent to ordinary observation. The one takes its food into an internal cavity (the stomach), from which it is absorbed into the system : the other absorbs its food directly by its surface, by its roots, leaves, &c. Both possess organs; but the limbs or members of the animal do not at all resemble the roots, leaves, blossoms, &c. of the plant. All these distinctions, however, gradu- ally disappear, as we come to the lower kinds of plants and the lower animals. Many animals (such as barnacles, coral-animals, and polyps) are fixed to some support as completely as the plant is to the soil ; while many plants are not fixed, and some move from place to place by powers of their own. All animals move some of their parts freely ; yet in the extent and rapidity of the motion many of them are surpassed by the common Sensitive Plant, by the Venus's Fly-trap, and by some other vegetables ; while whole tribes of aquatic plants are so freely and briskly locomotive, that they have until lately been taken for animals. It is among these microscopic tribes that the animal and vegetable kingdoms most nearly approach each other, — so nearly, that it is still uncertain where to draw the line between them. 6. Since the difficulty of distinguishing between animals and plants occurs only, or mainly, in those forms which from their minuteness are beyond ordinary observation, we need not further eoneern ourselves with the question here. One, and probably the most absolute, difference, however, ought to be mentioned at the outset, because it enables us to see what plants are made for. It is this : — 7. Vegetables are nourished by the mineral kingdom, that is, by the ground and the air, which supply all they need, and which they are adapted to live upon ; while animals are entirely nourished by N<0'<-ta!>l.-s. The great use of plants therefore is, to take portions of LESSON 1.] BOTANY, WHAT IT RELATES TO. 3 earth and air, upon which animals cannot subsist at all, and to con- vert these into something upon which animals can subsist, that is, into food. All food is produced by plants. Hqw this is done, it is the province of Vegetable Physiology to explain. 8. Botany is the name of the science of the vegetable kingdom in general. 0. Physiology is the study of the way a living being lives, and grows, and performs its various operations. The study of plants in this view is the province of Vegetable Physiology. The study of the form and structure of the organs or parts of the vegetable, by which its operations are performed, is the province of Structural Botany. The two together constitute Physiological Botany. With this de- partment the study of Botany should begin; both because it lies at the foundation of all the rest, and because it gives that kind of knowledge of plants which it is desirable every one should possess ; that is, some knowledge of the way in which plants live, grow, and fulfil the purposes of their existence. To this subject, accordingly, a large portion of the following Lessons is devoted. 10. The study of plants as to their kinds is the province of Sys- tematic Botany. An enumeration of the kinds of vegetables, as far as known, classified according to their various degrees of resemblance Dr difference, constitutes a general System of plants. A similar ac- count of the vegetables of any particular country or district is called a Flora of that country or district. 1 1 . Other departments of Botany come to view when — instead of regarding plants as to what they are in themselves, or as to their relationship with each other — we consider them in their relations to other things. Their relation to the earth, for instance, as respects their distribution over its surface, gives rise to Geographical Botany, or Botanical Geography. The study of the vegetation of former times, in their fossil remains entombed in the crust of the earth, gives rise to Fossil Botany. The study of plants in respect to their uses to man is the province of Agricultural Botany, Medical Botany, and the like. 4 GROWTH OF THE PLANT FROM THE SEED. [LESSON 2. LESSON II. THE GROWTH OF THE PLANT FROM THE SEED. 12. The Course Of Vegetation, We see plants growing from the seed in spring-time, and gradually developing their parts : at length they blossom, bear fruit, and produce seeds like those from which they grew. Shall we commence the study of the plant with the full-grown herb or tree, adorned with flowers or laden with fruit ? Or shall we commence with the seedling just rising from the ground ? On the whole, we may get a clearer idea of the whole life and structure of plants if we begin at the beginning, that is, with the plantlet springing from the seed, and follow it throughout its course of growth. This also agrees best with the season in which the study of Botany is generally commenced, namely, in the spring of the year, when the growth of plants from the seed can hardly fail to attract attention. Indeed, it is this springing forth of vegeta- tion from seeds and buds, after the rigors of our long winter, — clothing the earth's surface almost at once with a mantle of freshest verdure, — which gives to spring its greatest charm. Even the dullest beholder, the least observant of Nature at other seasons, can then hardly fail to ask : What are plants ? How do they live and grow ? What do they live upon ? What is the object and use of vegetation in general, and of its particular and wonderfully various forms ? These questions it is the object of the present Lessons to answer, as far as possible, in a simple way. 13. A reflecting as well as observing person, noticing the re- semblances between one plant and another, might go on to inquire whether plants, with all their manifold diversities of form and aj>j>earanee, are not all constructed on one and the same general plan. It will become apparent, as we proceed, that this is the case; — that one common plan may be discerned, which each par- ticular plant, whether herb, shrub, or tree, has followed much more closely than would at first view be supposed. The differences, wide as they are, are merely incidental. What is true in a general way of any ordinary vegetable, will be found to be true of all, only with great variation in the details. In the same language, though in varied phrase, the hundred thousand kinds of plants repeat the same LESSON 2.] GROWTH OF THE PLANT FROM THE SEED, story, — are the living witnesses and illustrations of one and the same plan of Creative Wisdom in the vegetable world. So that the study of any one plant, traced from the seed it springs from round to the seeds it produces, would illustrate the whole subject of vege- table life and growth. It matters little, therefore, what particular plant we begin with. 14. The Germinating Plantlet, Take for example a seedling Maple. Sugar Maples may be found in abundance in many places, starting from the seed (i. e. germinating) in early spring, and Red Maples at the beginning of summer, shortly after the fruits of the season have ripened and fallen to the ground, f A pair of narrow green leaves raised on a tiny stem make up the whole plant at its first appearance (Fig. 4). Soon a root appears at the lower end of this stemlet ; then a little bud at its upper end, between the pair of leaves, which soon grows into a second joint or stem bearing another pair of leaves, Jresembling the ordinary leaves of the Red Maple, which the first did not. Figures 5 and 6 represent these steps in the growth. 15. Was this plantlet formed in the seed at the time of germination, something as the chick is formed in the egg during the process of incu- bation ? Or did it. exist before in the seed, ready formed ? To decide this question, we have only to inspect a sound seed, which in this instance requires no microscope, nor any other instrument than a sharp knife, by which the coats of the seed (previously soaked in water, if dry) may be laid open. We find within the seed, in this case, the little plantlet ready formed, and nothing else (Fig. 2) ; — namely, a pair of leaves like those of the earliest seedling (Fig. 4), only smaller, borne on a stemlet just like that of the seedling, only much shorter, and all snugly coiled up within the protecting seed-coat. The plant then exists beforehand in the seed, in miniature. It was not formed, but only devel- FIG. 1. A winged fruit of Red Maple, witli the seed-bearing portion cut open, to show the seed. 2. This seed cut open to show the embryo plantlet within, enlarged. 3. The embryo taken out whole, and partly unfolded. 4. The same after it has begun to grow ; of the natural size. 1* 6 GROWTH OF THE PLANT FROM THE SEED. [LESSON 2. oped, in germination ; when it had merely to unfold and grow, — to elongate its rudimentary stem, which takes at the same time an upright position, so as to bring the leaf-bearing end into the light and air, where the two leaves expand ; while from the opposite end, now pushed farther downwards into the soil, the root begins to grow. All this is true in the main of all plants that spring from real seeds, although with great diversity in the particulars. At least, there is hardly an excep- tion to the fact, that the plantlet exists ready formed in the seed, in some shape or other. 16. The rudimentary plantlet contained in the seed is called an Embryo. Its little stem is named the Radicle, because it was supposed to be the root, when the difference between the root and stem was not so well known as now. It were better to name it the Caulicle (i. e. little stem) ; but it is not expedient to change old names. The seed-leaves it bears on its sum- mit (here two in number) are technically called Cotyledons. The little bud of undeveloped leaves which is to be found between the co- tyledons before germination in many cases (as in the Pea, Bean, Fig. 17, &c.), has been named the Plumule. 17. In the Maple (Fig. 4), as also in the Morning-Glory (Fig. 28), and the like, this bud, or plumule, is not seen for some days after the seed-leaves are expanded. But soon it appears, in the Maple as a pair of minute leaves (Fig. 5), erelong raised on a stalk which carries them up to some distance above the cotyledons. The plantlet (Fig. 6) now consists, above ground, of two pairs of leaves, viz. : 1. the cotyledons or seed-leaves, borne on the summit of the original stemlet (the radicle) ; and 2. a pair of ordinary leaves, raised on a second joint of stem which has grown from the top of the first. Later, a third pair of leaves is formed, and raised on a third joint of stem, proceeding from the summit of the second (Fur. 7), just as that did from the first; and so on, until the germi- nating plant let becomes a tree. FIG. 5. Germinating Red Maple, which has produced its root beneath, and [a developing a second pair of lcav«s above. C. Same, further advanced. LESSON 2.] GROWTH OF THE PLANT FROM THE SEED. 18. So the youngest seedling, and even the embryo in the seed, is already an epitome of the herb or tree. It has a stem, from the lower end of which it strikes root : and it has leaves. The tree itself in its whole vegetation has nothing more in kind. To become a tree, the plantlet has only to repeat itself upwardly by producing more similar parts, — that is, new por- tions of stem, with new and larger leaves, in succession, — while beneath, it pushes its root deeper and deeper into the soil. 19. The Opposite Growth of Root and Stem began at the beginning of germi- nation, and it continues through the whole life of the plant. While yet buried in the soil, and perhaps in total darkness, as soon as it begins to grow, the stem end of the embryo points towards the light, — curving or turning quite round if it happens to lie in some other direction, — and stretches upwards into the free air and sunshine ; while the root end as uniformly avoids the light, bends in the opposite direction to do so if necessary, and ever seeks to bury itself more and more in the earth's bosom. How the plantlet makes these movements we cannot explain. But the object of this instinct is obvious. It places the plant from the first in the proper position, with its roots in the moist soil, from which they are to absorb nourishment, and its leaves in the light and air, where alone they can fulfil their office of digesting what the roots absorb. 20. So the seedling plantlet finds itself provided with all the organs of vegetation that even the oldest plant possesses, — namely, root, stem, and leaves ; and has these placed in the situation where each is to act, — the root in the soil, the foliage in the light and air. Thus established, the plantlet has only to set about its proper work. 21. The different Mode of Growth of Root and Stem may also be here mentioned. Each grows, not only in a different direction, but in a different way. The stem grows by producing a set of joints, each from FIG. 7. Germinating Red Maple, further developed. 8 GROWTH OF THE PLANT FROM Tilt: SEED. [LESSON 2. the summit of its predecessor ; and each joint elongates throughout every part, until it reaches its full length. The root is not composed of joints, and it lengthens only at the end. The stem in the embryo (viz. the radicle) has a certain length to begin with. In the pump- kin-seed, for instance (Fig. 9), it is less than an eighth of an inch long : but it grows in a few days to the length of one or two inches (Fig. 10), or still more, if the seed were deeper covered by the soil. It is by this elongation that the seed-leaves are raised out of the soil, so as to expand in the light and air. The length they acquire varies with the depth of the covering. When large and strong seeds are too deeply buried, the stemlet sometimes grows to the length of several inches in the endeavor to bring the seed-leaves to the sur- face. The lengthening of the succeeding joints of the stem serves to separate the leaves, or pairs of leaves, from one another, and to ex- pose them more fully to the light. 22. The root, on the other hand, begins by a new formation at the base of the embryo stem ; and it continues to increase in length solely by additions to the extremity, the parts once formed scarcely elongating at all afterwards. This mode of growth is well adapted to the circumstances in which roots are placed, leaving every part undisturbed in the soil where it was formed, while the ever-advan- cing points readily insinuate themselves into the crevices or looser portions of the soil, or pass around the surface of solid obstacles. LESSON 3.] GROWTH OF THE PLANT FROM THE SEED. 9 LESSON III. GROWTH OF THE PLANT FROM THE SEED. Continued. \23) So a plant consists of two parts, growing in a different manner, as well as in opposite directions. One part, the root, grows down- wards into the soil : it may, therefore, be called the descending axis. The other grows upwards into the light and air : it may be called the ascending axis. The root grows on continuously from the ex- tremity, and so does not consist of joints, nor does it bear leaves, or anything of the kind. The stem grows by a succession of joints, each bearing one or more leaves on its summit. Root on the one hand, and stem with its foliage on the other, make up the whole plantlet as it springs from the seed ; and the full-grown herb, shrub, or tree has nothing more in kind, — only more in size and number. Before we trace the plantlet into the herb or tree, some- other cases of the growth of the plantlet from the seed should be studied, that we may observe how the same plan is worked out under a variety of forms, with certain differences in the details. The mate- rials for this study are always at hand. We have only to notice what takes place all around us in spring, or to plant some common seeds in pots, keep them warm and moist, and watch their germination. 24. The Germinating Plantlel feeds on Nourishment provided beforehand. The embryo so snugly ensconced in the seed of the Maple (Fig. 2, 3, 4) has from the first a miniature stem, and a pair of leaves already green, or which become green as soon as brought to the light. It has only to form a root by which to fix itself to the ground, when it becomes a perfect though diminutive vegetable, capable of providing for itself. This root can be formed only out of proper material : neither water nor anything else which the plantlet is imbibing from the earth will answer the purpose. The proper material is nourish- ing matter, or prepared food, more or less of which is always pro- vided by the parent plant, and stored up in the seed, either in the embryo itself, or around it. In the Maple, this nourishment is stored up in the thickish cotyledons, or seed-leaves. And there is barely enough of it to make the beginning of a root, and to provide for the lengthening of the stemlet so as to bring up the unfolding seed-leaves where they may expand to the light of day. But when this is done, 10 GROWTH OF THE PLANT FROM THE SEED. [LESSON 3. the tiny plant is already able to shift for itself; — that is, to live and continue its growth on what it now takes from the soil and from the air, and elaborates into nourishment in its two green leaves, under the influence of the light of the sun. 25. In most ordinary plants, a larger portion of nourishment is provided beforehand in the seed ; and the plantlet consequently is not so early or so entirely left to its own resources. Let us examine a number of cases, selected from very common plants. Sometimes, as has just been stated, we find this 26. Deposit Of Food in the Embryo itself, And we may observe it in every gradation as to quantity, from the Maple of our first illus- tration, where there is very little, up to the Pea and the Horsechestnut, where there is as much as there possibly can be. If we strip off the coats from the large and flat seed of a Squash or Pumpkin, we find nothing but the em- bryo within (Fig. 9) ; and almost the whole bulk of this consists of the two seed-leaves. That these contain a good supply of nourishing matter, is evident from their sweet taste and from their thickness, although there is not enough to obscure their leaf-like appearance. It is by feeding on this supply of nour- ishment that the germinating Squash or Pumpkin (Fig. 10) grows so rapidly and so vigorously from the seed, — lengthening its stemlet to more than twenty times the length it had in the seed, and thickening it in proportion, — sending out at once a number of roots from its lower end, and soon developing the plumule (16) from its upper end into a third leaf : meanwhile the two cotyledons, relieved from the nourishment with which their tissue was gorged, have expanded into useful green leaves. 27. For a stronger instance, take next the seed of a Plum or Peach, or an Almond, or an Apple-seed (Fig. 11, 12), which shows FIG. 9. Embryo of a Pumpkin, of the natural size ; the cotyledons a little opened. 10. The same, when it has germinated- LESSON 3.] GROWTH OF THE PLANT FROM THE SEED. 11 the same tiling on a smaller scale. The embryo, which here also makes up the whole bulk of the kernel of the seed, differs from that of the Pumpkin only in having the seed-leaves more thickened, by the much larger quantity of nourishment stored up in their tissue, — so large and so pure in- deed, that the almond becomes an article of food. Fed by this abundant supply, the second, and even the third joints of the stem, with their leaves, shoot forth as soon as the stemlet comes to the surface oi the soil. The Beech-nut (Fig. 13), with its sweet and eatable kernel, consisting mainly of a pair of seed-leaves folded together, and gorged writh nourishing matter, offers another instance of the same sort : this ample store to feed upon enables the germinating plantlet to grow with remarkable vigor, and to develop a second joint of stem, with its pair of leaves (Fig. 14), before the first pair has expanded or the root has ob- tained much foothold in the soil. 28. A Bean affords a similar and more familiar illustration. Here the co- tyledons in the seed (Fig. 1C) are so thick, that, although they are raised out of ground in the ordinary way in ger- mination (Fig. 17), and turn greenish, yet they never succeed in becoming leaf- like, — never display their real nature of leaves, as they do so plainly in the Ma- ple (Fig. 5), the Pumpkin (Fig. 10), the Morning-Glory (Fig. 8, 26-28), &c. Turned to great account as magazines of food for the germinating plantlet, they fulfil this special office admirably, but FIG. 11. An Apple-seed cut through lengthwise, showing the embryo with its thickened cotyledons. 12. The embryo of the Apple, taken out whole, its cotyledons partly separated. FIG. 13.

[LESSON 3. they were so gorged and, as it were, misshapen, that they became quite unfitted to perform the office of foliage. This office is accordingly first performed by the succeeding pair of leaves, those of the plumule (Fig. 17, 18), which is put into rapid growth by the abundant nourishment contained in the large and thick seed-leaves. The latter, having fulfilled this office, soon wither and fall away. 29. This is carried a step farther in the Pea (Fig. 19, 20), a near relative of the Bean, and in the Oak (Fig. 21, 22), a near relative of the Beech. The differ- ence in these and many other similar cases is this. The cotyledons, which make up nearly the whole bulk of the seed are exces- sively thickened, so as to become nearly hemispherical in shape. They have lost all likeness to leaves, and all power of ever fulfilling the office of leaves. Ac- cordingly in germination they remain unchanged within the husk or coats of the seed, never growing themselves, but supplying abundant nourishment to the plumule (the bud for the forming stem) between them. This pushes forth from the seed, shoots upward, and gives rise FIG. If!.

LESSON 3.] GROWTH OF THE PLANT FROM THE SEED. 13 to the first leaves that appear. In most cases of the sort, the radicle, or short original stemlet of the embryo be- low the cotyledons (which is plainly shown in the Pea, Fig. 19), lengthens very little, or not at all ; and so the cotyledons remain under ground, if the seed was covered by the soil, as every one knows to be the case with Peas. In these (Fig. 20), as alsa in the Oak (Fig. 22), the leaves of the first one or two joints are imperfect, and mere small scales; but genuine leaves immedi- ately follow. The Horsechestnut and Buck- eye (Fig. 23, 24) furnish another instance of the same sort. These trees are nearly related to the Maple ; but while the seed- leaves of the Maple show themselves to be leaves, even in the seed (as we have already seen), and when they germinate fulfil the office of ordinary leaves, those of the Buckeye and of the Horsechestnut (Fig. 23), would never be suspected to be the same organs. Yet they are so, only in another shape, — exceedingly thickened by the accumulation of a great quantity of starch and other nourishing matter in their substance ; and besides, their contigu- ous faces stick together more or less firmly, so that they never open. But the stalks of these seed-leaves grow, and, as they lengthen, push the radicle and the plumule out of the seed, when the former develops downwardly the root, the latter upwardly the leafy stem and all it bears (Fig. 24). 30. Deposit of Food outside of the Embryo, Very often the nourish- ment provided for the seedling plantlet is laid up, not in the embryo itself, but around it. A good instance to begin with is furnished by the common Morning- Glory, or Convolvulus. The embryo, taken out of the seed and straightened, is shown in Fig. 26. it consists of a short stemlet and of a pair of very thin and delicate green leaves, having no stock of nourishment in them for sustaining the FIG. 21. An acorn divided lengthwise. 22. The germinating Oak. 2 14 GROWTH OF THE PLANT FROM THE SEED. [LESSON 3. earliest growth. On cutting open the seed, however, we find this embryo (considerably crumpled or folded together, so as to occupy less space, Fig. 25) to be surround- ed by a mass of rich, mucilaginous matter (becoming rather hard and solid when dry), which forms the principal bulk of the seed. Upon this stock the embryo feeds in ger- mination ; the seed-leaves absorbing it into their tissue as it is rendered soluble (through certain chemical changes) and dissolved by the wa- ter which the germinating seed im- bibes from the moist soil. Having by this aid as se lengthened its radicle into a stem of consider- able length, and formed the beginning of a root at its lower end, already imbedded in the soil (Fig. 27), the cotyledons now disengage themselves from the seed-coats, and ex- pand in the light as the first pair of leaves (Fig. 28). These immediately begin to elaborate, under the sun's influence, what the root imbibes from the soil, and the new nourishment so produced is used, partly to increase the size of the little stem, root, and leaves already existing, and partly to produce a second joint of stem with its le:if (Fig. 29), then a third with its leaf (Fjg. 8) ; and so on. ;;i. This mukTiKil store of food, deposited in the seed along with the embryo (but not in its substance), the old botanists likened to FIG. 23. Buckeye : a seed divided. 24. A similar seed in pc-mination.

Food of this sort for the plant is also food for animals, or for man ; and it is this albumen, the floury part of the seed, which forms the principal bulk of such important grains' as those of Indian Corn (Fig. 38 - 40), Wheat, Rice, Buck- wheat, and of the seed of Four-o'clock, (Fig. 36, 37), and the like. In all these last-named cases, it may be ob- served that the embryo is not enclosed in the albumen, but placed on one side of it, yet in close contact with it, so that the embryo may absorb readily from it the nourishment it requires when it begins to grow. Sometimes the embryo is coiled around the outside, in the form of a ring, as in the Purslane and the Four-o'clock (Fig. 36, 37) ; sometimes it is coiled within the albumen, as in the Potato (Fig. 34, 35) ; some- times it is straight in the centre of the albumen, occupying nearly its whole length, as in the Barberry (Fig. 32, 33), or much smaller and near one end, as in the Iris (Fig. 43) ; or some- times so minute, in the midst of the al- bumen, that it needs a magnifying-glass to find it, as in the But- 31 37 FIG. 99.

Nothing is more curious than the various shapes and positions of the embryo in the seed, nor more interesting than to watch its de- velopment in germination. One point is still to be noticed, since the botanist considers it of much importance, namely : — 32. The Kinds of Embryo as to the Number of Cotyledons, In all the figures, it is easy to see that the embryo, however various in shape, is constructed on one and the same plan ; — it consists of a radicle or stemlet, with a pair of cotyledons on its summit. Botanists there- fore call it dicotyledonous, — an inconveniently long word to express the fact that the embryo has two cotyledons or seed-leaves. In many cases (as in the Buttercup), the cotyledons are indeed so minute, that they are discerned only by the nick in the upper end of the little embryo ; yet in germination they grow into a pair of seed-leaves, just as in other cases where they are plain to be seen, as leaves, in the seed. But in Indian Corn (Fig. 40), in Wheat, the Onion, the Iris (Fig. 43), &c., it is well known that only one leaf appears at first from the sprouting seed : in these the embryo has only one cotyle- don, and it is therefore termed ky the botanists monocotyledo- 40 nous ; — an extremely long word, like the other, of Greek derivation, which means one-cotyle- doned. The rudiments of one or more other leaves are, indeed, commonly present in this sort of embryo, as is plain to see in Indian Corn (Fig. 38 - 40), but they form a bud situated above or within the cotyledon, and enclosed by it more or less completely ; so that they evidently belong to the plumule (1G) ; and these leaves appear in the seedling plantlet, each from within its predecessor, and there- fore originating higher up on the forming stem (Fig. 42, 44). This will readily be understood from the accompanying figures, with their explanation, which the student may without difficulty verify for him- FIG. 38. A grain of Indian Corn, flatwise, cut away a little, so as to show the embryo, lying on the albumen, which makes the principal bulk of the seed. FIG. 39. Another grain of Corn, cut through the middle in the opposite direction, divid- ing the embryo through its thick cotyledon and its plumule, the latter consisting of two J«TI\ •«•-, ciiu' enclosing the other.

LESSON 3.] GROWTH OF THE PLANT FROM THE SEED. 17 self, and should do so, by examining grains of Indian Corn, soaked in water, before and also during germination. In the Onion, Lily, and the Iris (Fig. 43), the monocotyledonous embryo is simpler, consisting apparently of a simple oblong or cylindrical body, in which no distinction of parts is visible : the lower end is radicle, and from it grows the root ; the rest is a cotyledon, which has wrapped up in it a minute plumule, or bud, that shows itself when the seeds sprout in germi- nation. The first leaf which appears above ground in all these cases is not the cotyledon. In all seeds with one coty- ledon to the embryo, this remains in the seed, or at least its upper part, while its lengthening base comes out, so as to extricate the plumule, which shoots upward, and de- velops the first leaves of the plantlet. These appear one above or within the other in succes- sion,— as is shown in Fig. 42 and Fig. 44, — the first commonly in the form of a little scale or imperfect leaf; the second or third and the 4l following ones as the real, ordinary leaves of the plant. Meanwhile, from the root end of the embryo, a root (Fig. 41, 44), or soon a whole cluster of roots (Fig. 42), makes its appearance. 33. In Pines, and the like, the embryo con- sists of a radicle or stemlet, bearing on its summit three or four, or often from five to ten slender cotyledons, arranged in a circle (Fig. 45), and expanding at once into a circle of as many green leaves in germination (Fig. 46). Such embryos are said to be polycotyledonous, that is, as the word denotes, many- cotyledoned. 34. Plan of Vegetation, The student 42 who has understandingly followed the growth of the embryo in the seed into the seedling plantlet, — com- posed of a root, and a stem of two or three joints, each bearing a FIG. 41. Grain of Indian Corn in germination. FIG. 42. The same, further advanced- 2* 18 GROWTH OF THE PLANT FROM THE SEED. [LESSON 3. leaf, or a pair (rarely a circle) of leaves, — will have gained a cor- rect idea of the plan of vegetation in general, and have laid a good foundation for a knowledge of the whole structure and physiology 43 of plants. For the plant goes on to grow in the same way throughout, by mere repetitions of what the early germinating plantlet displays to view, — of what was contained, in miniature or in rudiment, in the seed itself. So far as vegetation is concerned (leaving out of view for the present the flower and fruit), the full-grown leafy herb or tree, of whatever size, has nothing, and does nothing, which the seedling plantlet does not have and do. The whole mass of stem or trunk and foliage of the complete plant, even of the largest forest-tree, is composed of a succession or multiplication of similar parts, — one arising from the summit of another, — each, so to say, the offspring of the preceding and the parent of the next. /-• £ \35y In the same way that the earliest portions of the seedling stem, with the leaves they bear, are successively produced, so, joint by joint in direct succes- sion, a single, simple, leafy stem is developed and carried up. Of such a simple leafy stem many a plant consists (before flowering, at least), — many herbs, such as Sugar-Cane, Indian Corn, the Lily, the tall Banana, the Yucca, &c. ; and among trees the 44 Palms and the Cycas (wrongly called Sago Palm) exhibit the same simplicity, their stems, of whatever age, being unbranched columns 45 46 (Fig. 47). (Growth "._ diameter is of course to be considered, as well as growth in length. That, and the question how growth of any kind takes place, we will consider hereafter.) But more commonly, as soon as the plant has produced a main stem of a cer- tain length, and displayed a certain amount of foliage, it begins to FIG. 43.

THE GROWTH OF PLANTS FROM BUDS AND BRANCHES. 37. WE have seen how the plant grows so as to produce a root, and a simple stem with its foliage. Both the root and stem, how- ever, generally branch. (38. The branches of the root arise without any particular order. There is no telling beforehand from what part of a main root they will spring. But the branches of the stem, except in some extra- ordinary cases, regularly arise from a particular place. Branches or shoots in their undeveloped state are 39. Buds, These regularly appear in the axils of the leaves, — that is, in the angle formed by the leaf with the stem on the upper side ; and as leaves are symmetrically arranged on the stem, the buds, and the branches into which the buds grow, necessarily par- take of this symmetry. 40. We do not confine the name of bud to the scaly winter-buds which are so conspicuous on most of our shrubs and trees in winter and spring. It belongs as well to the forming branch of any herb, at its first appearance in the axil of a leaf. In growing, buds lengthen into branches, just as the original stem did from the plumule of the embryo (16) when the seed germinated. Only, while the original stem is implanted in the ground by its root, the branch is implanted on the stem. Branches, therefore, are repetitions of the main stem. They consist of the same parts, — namely, joints of stem and leaves, — growing in the same way. And in the axils of their leaves another crop of buds is naturally produced, giving rise to another generation of branches, which may in turn produce still another generation ; and so on, — until the tiny and simple seedling develops into a tall and spreading herb or shrub ; or into a massive tree, with its hundreds of annually increasing branches, and its thousands, prrliaj)- millions, of leaves. 1 1 . The herb and the tree grow in the same way. The difference is only in size and duration. An Herb dies altogether, or dies down to the ground, after it has ripened its fruit, or at the approach of winter. LESSON 4.] GROWTH OF PLANTS FROM BUDS. 21 An annual herb flowers in the first year, and dies, root and all, after ripening its seed : Mustard, Peppergrass, Buckwheat, &c., are examples. A biennial herb — such as the Turnip, Carrot, Beet, and Cabbage — grows the first season without blossoming, survives the winter, flowers after that, and dies, root and all, when it has ripened its seed. A perennial herb lives and blossoms year after year, but dies down to the ground, or near it, annually, — not, however, quite down to the root : for a portion of the stem, with its buds, still survives ; and from these buds the shoots of the following year arise. A Shrub is a perennial plant, with woody stems which continue alive and grow year after year. A Tree differs from a shrub only in its greater size. 42. The Terminal Bud, There are herbs, shrubs, and trees which do not branch, as we have already seen (35) ; but whose stems, even when they liva for many years, rise as a simple shaft (Fig. 47). These plants grow by the continued evolution of a bud which crowns the summit of the stem, and which is therefore called the terminal bud. This bud is very conspicuous in many branching plants also ; as on all the stems or shoots of Maples (Fig. 53), Horsechestnuts (Fig. 48), or Hickories (Fig. 49), of a year old. When they grow, they merely prolong the shoot or stem on which they rest. On these same shoots, however, other buds are to be seen, regularly arranged down their sides. We find them situated just over broad, flattened places, which are the scars left by the fall of the leaf-stalk the autumn previous. Before the fall of the leaf, they would have been seen to occupy their axils (39) : so they are named 43. Axillary Buds, They were formed in these trees early in the summer. Occasionally they grow at the time into branches : at least, some of them are pretty sure to do so, in case the growing terminal bud at the end of the shoot is injured or destroyed. Otherwise they lie dormant until the spring. In many trees shrubs (such for example as the Sumach and Honey-Locust) lese axillary buds do not show themselves until spring; but if FIG. 48. Shoot of Horsechestnut, of one year's growth, taken in autumn after the leaves ive fallen. 22 GROWTH OF PLANTS FROM BUDS. [LESSON 4. searched for, they may be detected, though of small size, hidden under the bark. Sometimes, although early formed, they are con- cealed all summer long under the base of the leaf- stalk, hollowed out into a sort of inverted cup, like a candle-extinguisher, to cover them ; as in the Locust, the Yellow-wood, or more strikingly in the Button- wood or Plane-tree (Fig. 50). 44. Such large and conspicuous buds as those of the Horsechestnut, Hickory, and the like, are scaly ; the scales being a kind of imperfect leaves. The use of the bud-scales is obvious ; namely, to protect the tender young parts beneath. To do this more effectually, they are often coated on the outside with a varnish which is impervious to wet, while within they, or the parts they enclose, are thickly clothed with down or wool ; not really to keep out the cold of winter, which will of course penetrate the bud in time, but to shield the interior against sudden changes from warm to cold, or from cold to warm, which are equally injurious. Scaly buds commonly belong, as would be expect- ed, to trees and shrubs of northern climates ; while naked buds are usual in tropical regions, as well as in herbs everywhere which branch during the summer's growth and do not endure the winter. 4.V But naked buds, or nearly naked, also occur in several of our own trees and shrubs ; sometimes pretty large ones, as those of Hob- FIG. 49, Annual shoot of the Phagbark Hickory. FIG. 50. Bud and leaf of tho Buttnnwood, or American Piano-tree. LESSON 4.] GROWTH OF PLANTS FROM BUDS. 23 blebush (while those of the nearly-related Snowball or High Bush- Cranberry are scaly) ; but more commonly, when naked buds occur in trees and shrubs of our climate, they are small, and sunk in the bark, as in the Sumac ; or even partly buried in the wood until they begin to grow, as in the Honey-Locust. 40. Vigor Of Vegetation from Buds, Large and strong buds, like those of the Horsechestnut, Hickory, and the like, on inspection will be found to contain several leaves, or pairs of leaves, ready formed, folded and packed away in small compass, just as the seed-leaves are packed away in the seed : they even contain all the blossoms of the ensuing season, plainly visible as small buds. And the stems upon which these buds rest are filled with abundant nourishment, which was deposited the summer before in the wood or in the bark. Under the surface of the soil, or on it, covered with the fallen leaves of autumn, we may find similar strong buds of our perennial herbs, in great variety ; while beneath are thick roots, rootstocks, or tubers, charged with a great store of nourishment for their use. As we regard these, we shall readily perceive how it is that vegetation shoots forth so vigorously in the spring of the year, and clothes the bare and lately frozen surface of the soil, as well as the naked boughs of trees, almost at once with a covering of the freshest green, and often with brilliant blossoms. Everything was prepared, and even formed, beforehand : the short joints of stem in the bud have only to lengthen, and to separate the leaves from each other so that they may unfold and grow. Only a small part of the vege- tation of the season comes directly from the seed, and none of the earliest vernal vegetation. This is all from buds which have lived through the winter. 47. This growth from buds, in manifold variety, is as interesting a subject of study as the growth of the plantlet from the seed, and is still easier to observe. We have only room here to sketch the general plan ; earnestly recommending the student to examine at- tentively their mode of growth in all the common trees and shrubs, when they shoot forth in spring. The growth of the terminal bud prolongs the stem or branch: the growth of axillary buds pro- duces branches. IS. The Arrangement of Branches is accordingly the same as of axillary buds ; and the arrangement of these buds is the same as that of the leaves. Now leaves are arranged in two principal ways : they are either opposite or alternate. Leaves are opposite when 24 GROWTH OF PLANTS FROM BUDS. [LESSON 4. there are two borne on the same joint of stem, as in the Horse- chestnut, Maple (Fig. 7), Honeysuckle (Fig. 132), Lilac, &c.; the two leaves in such cases being always opposite each other, that is, on exactly opposite sides of the stem. Here of course the buds in their axils are opposite, as we observe in Fig. 48, where the leaves have fallen, but their place is shown by the scars. And the branches into which the buds grow are likewise opposite each other in pairs. 49. Leaves are alternate when there is only one from each joint of stem, as in the Oak (Fig. 22), Lime-tree, Poplar, Buttonwood (Fig. 50), Morning- Glory (Fig. 8), — not counting the seed-leaves, which of course are opposite, there being a pair of them ; also in Indian Corn (Fig. 42), and Iris (Fig. 44). Consequently the axillary buds are also alternate, as in Hickory (Fig. 49) ; and the branches they form alternate, — making a different kind of spray from the other mode, — one branch shooting on the one side of the stem and the next on some other. For in the alternate arrangement no leaf is on the same side of the stem as the one next above or next below it. (50. Branches, therefore, are arranged with symmetry ; and the mode of branching of the whole tree may be foretold by a glance at the arrangement of the leaves on the seedling or stem of the first year. This arrangement of the branches according to that of the leaves is always plainly to be recognized ; but the symmetry of branches is rarely complete. This is owing to several causes ; mainly to one, viz.: — 51. It never happens that all the bud& grow. If they did, there would be as many branches in any year as there were leaves the year before. And of those which do begin to grow, a large portion perish, sooner or later, for want of nourishment or for want of light. Those which first begin to grow have an advantage, which they are apt to keep, taking to themselves the nourishment of the stem, and starving the weaker buds. 52. In the Horsechestnut (Fig. 48), Hickory (Fig. 49), Mag- nolia, and most other trees with large scaly buds, the terminal bud is the strongest, and has the advantage in growth, and next in strength are the upper axillary buds: while the former continues the shoot of the last year, some of the latter give rise to branches, while the rest fail to grow. In the Lilac also, the upper axillary buds are stronger than the lower ; but the terminal bud rarely LESSON 4.] GROWTH OF PLANTS FROM BUDS. 25 appears at all ; in its place the uppermost pair of axillary buds grow, and so each stem branches every year into two ; making a re- peatedly two-forked ramification. 53. In these and many similar trees and shrubs, most of the shoots make a definite annual growth. That is, each shoot of the season develops rapidly from a strong bud in spring, — a bud which gen- erally contains, already formed in miniature, all or a great part of the leaves and joints of stem it is to produce, — makes its whole growth in length in the course of a few weeks, or sometimes even in a few days, and then forms and ripens its buds for the next year's similar rapid growth. 54. On the other hand, the Locust, Honey-Locust, Sumac, and, among smaller plants, the Rose and Raspberry, make an indefinite annual growth. That is, their stems grow on all summer long, until stopped by the frosts of autumn or some other cause ; con- sequently they form and ripen no terminal bud protected by scales, and the upper axillary buds are produced so late in the season that they have no time to mature, nor has the wood time to solidify and ripen. Such stems therefore commonly die at the top in winter, or at least all their upper buds are small and feeble ; and the growth of the succeeding year takes place mainly from the lower axillary buds, which are more mature. Most of our perennial herbs grow in this way, their stems dying down to the ground every year : the part beneath, however, is charged with vigorous buds, well pro- tected by the kindly covering of earth, ready for the next year's vegetation. 55. In these last-mentioned cases there is, of course, no single main stem, continued year after year in a direct line, but the trunk is soon lost in the branches ; and when they grow into trees, these commonly have rounded or spreading tops. Of such trees with deliquescent stems, — that is, with the trunk dissolved, as it were, into the successively divided branches, the common American Elm (Fig. 54) furnishes a good illustration. 56. On the other hand, the main stem of Pines and Spruces, as it begins in the seedling, unless destroyed by some injury, is carried on in a direct line throughout the whole growth of the tree, by the development year after year of a terminal bud : this forms a single, uninterrupted shaft, — an excurrent trunk, which can never be eon- nded with the branches that proceed from it. Of such spiry or Ire-shaped trees, the Firs or Spruces are the most perfect and 3 26 GROWTH OF PLANTS FROM BUDS. [LESSON 4. familiar illustrations (Fig. 54) ; but some other trees with strong terminal buds exhibit the same character for a certain time, and in a less marked degree. 57. Latent Buds, Some of the axillary buds grow the following year into branches ; but a larger number do not (51). These do not necessarily die. Often they survive in a latent state for some years, visible on the surface of the branch, or are smaller and concealed under the bark, resting on the surface of the wood : and when at any time the other buds or branches happen to be killed, these older latent buds grow to supply their place ; — as is often seen when the foliage and young shoots of a tree are destroyed by insects. The new shoots seen springing directly out of large stems may sometimes originate from such latent buds, which have preserved their life for years. But commonly these arise from 58. Adventitious Buds, These are buds which certain shrubs and trees produce anywhere on the surface of the wood, especially where it has been injured. They give rise to the slender twigs which often feather so beautifully the sides of great branches or trunks of our American Elms. They sometimes form on the root, which naturally is destitute of buds ; and they are sure to appear on the trunks and roots of Willows, Poplars, and Chestnuts, when these are wounded or mutilated. Indeed Osier- Willows are pollarded, or cut off, from time to time, by the cultivator, for the purpose of producing a crop of slender adventitious twigs, suitable for basket-work. Such branches, being altogether irregular, of course interfere with the natural sym- metry of the tree (50). Another cause of irregularity, in certain trees and shrubs, is the formation of what are called 59. Accessory or -Supernumerary Buds, There are cases where two, three, or more buds spring from the axil of a leaf, instead of the single one which is ordinarily found there. Sometimes they are placed one over the other, as in the Aristolochia or Pipe- Vine, and in the Tartarian Honeysuckle (Fig. 51) ; also in the Honey-Locust, and in the Walnut and Butternut (Fig. 52), where the upper supernumerary bud is a good way out of the axil and above the others. And this is here stronger FIG. 51. Tartarian Honeysuckle, with three accessory buds in one axil. LESSON 4.] GROWTH OF PLANTS FROM BUDS. 27 , than the others, and grows into a branch which is considerably out of the axil, while the lower and smaller ones commonly do not grow at all. In other cases the three buds stand side by side in the axil, as in the Hawthorn, and the Red Maple (Fig. 53). If these were all to grow into branches, they would stifle or jostle each other. But some of them are commonly flower-buds : in the Red Maple, only the middle one is a leaf-bud, and it does not grow until after those on each side of it have ex- panded the blossoms they contain. 60. Sorts Of Buds, It may be useful to enumerate the kinds of buds which have now been mentioned, referring back to the paragraphs in which the pe- culiarities of each are explained. Buds, then, are either terminal or lateral. They are Terminal when they rest on the apex of a stem (42). The earliest terminal bud is the plumule of the embryo (16). Lateral, when they appear on the side of a stem : — of which the only regular kind is the Axillary (43), namely, those which are situated in he axils of leaves. Accessory or Supernumerary (59), when two or more occur in addition to the ordinary axillary bud. 53 Adventitious (58), when they occur out of the .axils and without order, on stems or roots, or even on leaves. Any of these kinds may be, either Naked, when without coverings; or scaly, when protected by scales (44, 45). Latent, when they survive long without growing, and commonly without being visible externally (57). Leaf-buds, when they contain leaves, and develop into a leafy shoot. Flower-buds, when they contain blossoms, and no leaves, as the FIG. 52. Butternut branch, with accessory buds, the uppermost above the axil. FIG. 53. Red-Maple branch, with accessory buds placed side by side. 28 MORPHOLOGY OF ROOTS. [LESSON 5. side-buds of the Red-Maple, or when they are undeveloped blossoms. These we shall have to consider hereafter. Figure 54 represents a spreading-topped tree (American Elm), the stem dividing off into branches ; and some spiry trees (Spruces on the right hand, and two of the Arbor- Vitae on the left) with ex- current stems. LESSON V. MORPHOLOGY (i.e. VARIOUS SORTS AND FORMS) OF ROOTS. 61. Morphology, as the name (derived from two Greek words) denotes, is the doctrine of forms. In treating of forms in plants, the botanist is not confined to an enumeration or description of the shapes or sorts that occur, — which would be a dull and tedious business, — but he endeavors to bring to view the relations between one form and another ; and this is an interesting study. G2. Botanists give particular names to all the parts of plants, and also particular terms to express their principal varieties in form. They use these terms with great precision and advantage in describ- ing the species or kinds of plants. They must therefore be defined and explained in our books. But it would be a great waste of time LESSON 5.] MORPHOLOGY OF ROOTS. 29 for the young student to learn them by rote. The student should rather consider the connection between one form and another ; and notice how the one simple plan of the plant, as it has already been illustrated, is worked out in the greatest variety of ways, through the manifold diversity of forms which each of its three organs of vege- tation — root, stem, and leaf — is made to assume. 63. This we are now ready to do. That is, having obtained a g neral idea of vegetation, by tracing the plant from the seed and the bud into the herb, shrub, or tree, we proceed to contemplate the principal forms under which these three organs occur in different plants, or in different parts of the same plant ; or, in other words, to study the morphology of the root, stem, and leaves. 64. Of these three organs, the root is the simplest and the least varied in its modifications. Still it exhibits some widely different kinds. Going back to the beginning, we commence with 65. The simple Primary Root, which most plants send down from the root-end of the embryo as it grows from the seed ; as we have seen in the Maple (Fig 5 - 7), Morning-Glory (Fig. 8 and 28), Beech (Fig. 14, 15), Oak and Buckeye (Fig. 22-24), &c. This, if it goes on to grow, makes a main or tap root, from which side- branches here and there proceed. Some plants keep this main root throughout their whole life, and send off only small side branches ; as in the Carrot (Fig. 58) and Radish (Fig. 59) : and in some trees, like the Oak, it takes the lead of the side-branches for many years, unless accidentally injured, as a strong tap-root. But commonly the main root divides off very soon, and is lost in the branches.. We have already seen, also, that there may be at the beginning 66. Multiple Primary Roots, We have noticed them in the Pump- kin (Fig. 10), in the Pea (Fig. 20), and in Indian Corn (Fig. 42).. That is, several roots have started all at once, or nearly so, from the seedling stem, and formed a bundle or cluster (a fascicled root, as it is called), in place of one main root. The Bean, as we observe in Fig. 18, begins with a main root ; but some of its branches soon overtake it, and a cluster of roots is formed. 67. Absorption of Moisture by Roots, The branches of roots as they grow commonly branch again and again, into smaller roots or rootlets ; in this way very much increasing the surface by which the plant connects itself with the earth, and absorbs moisture from it. The whole surface of the root absorbs, so long as it is fresh and new ; and the newer the roots and rootlets are, the more freely do they 3* MORPHOLOGY OF ROOTS. [LESSON 5. imbibe. Accordingly, as long as the plant grows above ground, and expands fresh foliage, from which moisture much of the time largely escapes into the air, so long it continues to extend and multiply its roots in the soil beneath, renewing and increasing the fresh surface for absorbing moisture, in proportion to the demand from above. And when growth ceases above ground, and the leaves die and fall, or no longer act, then the roots generally stop growing, and their soft and tender tips harden. From this period, therefore, until growth begins anew the next spring, is the best time for transplant- ing ; especially for trees and shrubs, and herbs so large that they cannot well be removed without injuring the roots very mnch. 68. We see, on considering a moment, that an herb or a tree consists of two great surfaces, with a narrow part or trunk between them, — one surface spread out in the air, and the other in the soil. These two surfaces bear a certain proportion to each other ; and the upper draws largely on the lower for moisture. Now, when the leaves fall from the tree in autumn, the vast sur- face exposed to the air is reduced to a very small part of what it was before ; and the remainder, being covered with a firm bark, cannot lose much by evap- oration. In common herbs the whole surface above ground perishes in au- tumn ; and many of the rootlets die at the same time, or soon afterwards. So that the living vegetable is reduced for the time to the smallest compass, — to the thousandth or hundred-thou- sandth part of what it was shortly before, — and what remains alive rests in a dormant state, and may now be transplanted without much danger of harm. If any should doubt whether there is so great a difference between the summer and the winter size of plants, let them compare a lily-bulb with the full-grown Lily, or calculate the surface of foliage which FIG. r>f). HocdliiiR Maple, of the natural size, showing the root-hairs. 56. A bit of the end of the root magnified. LESSON 5.] MORPHOLOGY OF ROOTS. 31 a tree exposes to the air, as compared with the surface of its twigs. 69. The absorbing surface of roots is very much greater than it appears to be, on account of the root-hairs, or slender fibrils, which abound on the fresh and new parts of roots. These may be seen with an ordinary magnifying-glass, or even by the naked eye in many cases ; as in the root of a seedling Maple (Fig. 55), where the surface is thickly clothed with them. They are not root- lets of a smaller sort ; but, when more magnified, are seen to be mere elongations of the surface of the root into slender tubes, which through their very delicate walls imbibe moisture from the soil with great avidity. They are com- monly much longer than those shown in Fig. 56, which represents only the very tip of a root moderately magnified. Small as they are indi- vidually, yet the whole amount of absorbing surface added to the rootlets by the countless numbers of these tiny tubes is very great. 70. Roots intend- ed mainly for ab- sorbing branch free- ly, and are slender or thread-like. When the root is prin- cipally of this character it is said to be fibrous ; as in Indian Corn (Fig. 42), and other grain, and to some extent in all annual plants (41). 71. The Root as a Storehouse of Food, In biennial and many perennial herbs (41), the root answers an additional purpose. In the course of the season it becomes a storehouse of nourishment, and enlarges or thickens as it receives the accumulation. Such roots are said to be fleshy ; and different names are applied to them according to FIG. 57, 58, 59. Forms of fleshy or thickened roots. 32 MORPHOLOGY OF ROOTS. [LESSON 5. their shapes. We may divide them all into two kinds ; 1st, those consisting of one main root, and 2d, those without any main root. 72. The first are merely different shapes of the tap-root ; which is Conical, when it thickens most at the crown, or where it joins the stem, and tapers regularly downwards to a point, as in the Common Beet, the Parsnip, and Carrot (Fig. 58) : Turnip-shaped or napiform, when greatly thickened above ; but abruptly becoming slender below ; as the Turnip (Fig. 57) : and, Spindle-shaped, or fusiform, when thickest in the middle and tapering to both ends ; as the common Radish (Fig. 59). 73. In the second kind, where there is no main root, the store of nourishing matter may be distributed throughout the branches or cluster of roots gener- ally, or it may be accumulated in some of them, as we see in the tuberous roots of the Sweet Potato, the common Peony, and the Dahlia (Fig. 60). 74. All but the last of these illustra- trations are taken from biennial plants. These grow with a large tuft of leaves next the ground, and accumulate nour- ishment all the first summer, and store up all they produce beyond what is wanted at the time in their great root, which lives over the winter. We know very well what use man and other animals make of this store of food, in the form of starch, sugar, jelly, and the like. From the second year's growth we may learn what use the plant itself makes of it. The new shoots then feed upon it, and use it to form with great rapidity branches, flower-stalks, blossoms, fruit, and seed; and, having used it up, the whole plant dies when the seeds have ripened. 75. In the same way the nourishment contained in the separate tuberous roots of the Sweet Potato and the Dahlia (Fig. 60) is fed upon in the spring by the buds of the stem they belong to ; and as they are emptied of their contents, they likewise die and decay. But meanwhile similar stores of nourishment, produced by the second year's vegetation, are deposited in new roots, which live through the FIG. 60. Clustered tuberous roots of the Dahlia, with the bottom of the stem they belong to. LESSON 5.] MORPHOLOGY OF ROOTS. 33 next winter, and sustain the third spring's growth, and so on ; — these plants being perennial (41), or lasting year after year, though each particular root lives little more than one year. 76. Many things which commonly pass for roots are not really roots at all. Common potatoes are tuberous parts of stems, while sweet potatoes are roots, like those of the Dahlia (Fig. 60). The dif- ference between them will more plainly appear in the next Lesson. 77. Secondary Roots. So far we have considered only the original or primary root, — that which proceeded from the lower end of the first joint of stem in the plantlet springing from the seed, — and its subdivisions. We may now remark, that any other part of the stem will produce roots just as well, whenever favorably situated for it ; that is, when covered by the soil, which provides the darkness and the moisture which is congenial to them. For these secondary roots, as they may be called, partake of the ordinary disposition of the organ : they avoid the light, and seek to bury themselves in the ground. In Indian Corn we see roots early striking from the second and the succeeding joints of stem under ground, more abundantly than from the first joint (Fig. 42). And all stems that keep up a connection with the soil — such as those which creep along on or beneath its surface — are sure to strike root from almost every joint. So will most branches when bent to the ground, and covered with the soil : and even cuttings from the branches of most plants can be made to do so, if properly managed. Propagation by buds depends upon this. That is, a piece of a plant which has stem and leaves, either developed or in the bud, may be made to produce roots, and so become an independent plant. 78. In many plants the disposition to strike root is so strong, that they even will spring from the stem above ground. In Indian Corn, for example, it is well known that roots grow, not only from all those joints round which the earth is heaped in hoeing, but also from those several inches above the soil : and other plants produce them from stems or branches high in the air. Such roots are called 79. Aerial Roots, All the most striking examples of these are met with, as we might expect, in warmer and damper climates than ours, and especially in deep forests which shut out much of the light ; this being unfavorable to roots. The Mangrove of tropical shores, which occurs on our own southern borders ; the Sugar Cane, from which roots strike just as in Indian Corn, only from higher up the stem ; the Pandanus, called Screw Pine (not from its resemblance to a 34 MORPHOLOGY OF ROOTS- [LESSON 5. Pine-tree, but because it is like a Yine-apple plant) ; and the famous Banyan of India, and some other Fig-trees, furnish the most remark- able examples of roots, which strike from the stem or the branches in the open air, and at length reach the ground, and bury them- selves, when they act in the same manner as ordinary roots. 80. Some of our own common plants, however, produce small aerial rootlets ; not for absorbing nourishment, but for climbing. By these rootlets, that shoot out abundantly from the side of the stems and branches, the Trumpet Creeper, the Ivy of Europe, and our Poison Rhus, — here called Poison Ivy, — fasten themselves firmly to walls, or the trunks of trees, often ascending to a great height. Here roots serve the same purpose that tendrils do in the Grape- Vine and Virginia Creeper. / Another form, and the most aerial of all roots, since they never reach the ground, are those of 81. Epiphytes, or Air-Plants, These are called by the first name (which means growing on plants), because they are generally found upon the trunks and branches of trees ; — not that they draw any nourishment from them, for their roots merely adhere to the bark, and they flourish just as well upon dead wood or any other con- venient support. JThey are called air-plants because they really live altogether upon what they get from the air, as they have no connection with the soil. Hundreds of air-plants grow all around us without attracting any attention, because they are small or hum- ble. Such are the Lichens and Mosses that abound on the trunks or boughs of trees, especially on the shaded side, and on old walls, fences, or rocks, from which they obtain no nourishment. But this name is commonly applied only to the larger, flower-bearing plants which live in this way. These belong to warm and damp parts of the world, where there is always plenty of moisture in the air. The greater part belong to the Orchis family and to the Pine-Apple family ; and among them are some of the handsomest flowers known. "VVe have two or three flowering air-plants in the Southern States, though they are not showy ones. One of them is an Epidendrum Crowing on the boughs of the Great-flowered Magnolia: another is the Long-Moss, or Black Moss, so called, — although it is no Moss at all, — which hangs from the branches of Oaks and Pines in all the warm parts of the Southern States. (Fig 61 represents both of these. The upper is the Epidendrum conopseum; the lower, the Black Moss, Tillaridsia usneoides.) 82. Parasitic Plants exhibit roots under yet another remarkable LESSON MORPHOLOGY OF ROOTS. 35 aspect. For these are not merely fixed upon other plants, as air- plants are, but strike their roots, or what answer to roots, into them, and feed on their juices. Not only Moulds and Blights (which are plants of very low organization) live in this predacious way, but many flowering herbs, and even shrubs. One of the latter is the Mistletoe, the seed of which germinates on the bough of the tree where it falls or is left by birds ; and the forming root penetrates the bark and engrafts itself into the wood, to which it becomes united as firmly as a natural branch to its parent stem ; and indeed the parasite lives just as if it were a branch of the tree it grows and feeds on. A most common parasitic herb is the Dodder; which abounds in low grounds everywhere in summer, and coils its long and slender leafless, yellowish stems — resembling tangled threads of yarn — round and round the stalks of other plants ; wherever they touch piercing the bark with minute and very short rootlets in the form of suckers, which draw out the nourishing juices of the plants laid hold of. Other parasitic plants, like the Beech-drops and Pine-sap, fasten their roots under ground upon the roots of neighboring plants, and rob them of their rich juices. 86 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON LESSON VI. MORPHOLOGY OF STEMS AND BRANCHES. 83. THE growth of the stem in length, and the formation of branches, have been considered already. Their growth in thick- ness we may study to more advantage in a later Lesson. The very various forms which they assume will now occupy our attention, — beginning with 84. The Forms of Stems and Branches above ground, The principal differences as regards size and duration have been mentioned before (41); namely, the obvious distinction of plants into herbs, shrubs, and trees, which depends upon the duration and size of the stem. The stem is accordingly Herbaceous, when it dies down to the ground every year, or after blossoming. Suffrutescent, when the bottom of the stem above the soil is a little woody, and inclined to live from year to year. Suffruticose, when low stems are decidedly woody below, but herbaceous above. Fruticose, or shrubby, when woody, living from year to year, and of considerable size, — not, however, more than three or four tunes the height of a man. Arborescent, when tree-like in appearance, or approaching a tree in size. Arboreous, when forming a proper tree trunk. 85. When the stem or branches rise above ground and are ap- parent to view, the plant is said to be caulescent (that is, to have a caulis or true stem). When there is no evident stem above ground, but only leaves or leaf-stalks and flower-stalks, the plant is said to be acauJescent, i. e. stemless, as in the Crocus, Bloodroot, common Violets, &c., and in the Beet, Carrot, and Radish (Fig. 59), for the first season. There is a stem, however, in all such cases, only it remains on or beneath the ground, and is sometimes very short. Of course leaves and flowers do not arise from the root. These concealed soils of stem we will presently study. 86. The direction taken by stems, &c., or their mode of growth, LESSON 6.] SUCKERS, STOLONS^ AND OFFSETS. 37 gives rise to several terms, which may be briefly mentioned: — such as Diffuse, when loosely spreading in all directions. Declined, when turned or bending over to one side. Decumbent, reclining on the ground, as if too weak to stand. Assurgent or ascending, when rising obliquely upwards. Procumbent or prostrate, lying flat on the ground from the first. Creeping, or repent, when prostrate stems on or just beneath the ground strike root as they grow ; as does the White Clover, the little Partridge-berry, &c. Climbing, or scandent, when stems rise by clinging to other ob- jects for support, — whether by tendrils, as do the Pea, Grape- Vine, and Virginia Creeper (Fig. 62) ; by their twisting leaf-stalks, as the Virgin's Bower ; or by rootlets, like the Ivy, Poison Ivy, and Trumpet Creeper (80). Twining, or voluble, when stems rise by coiling themselves spirally around other stems or supports ; like the Morning- Glory and the Bean. 87. Certain forms of stems have received distinct names. The jointed stem of Grasses and Sedges is called by botanists a culm ; and the peculiar scaly trunk of Palms and the like (Fig. 47) is sometimes called a caudex. A few forms of branches the gardener distinguishes by particular names ; and they are interesting from their serving for the natural propagation of plants from buds, and for suggesting ways by which we artificially multiply plants that would not propagate themselves without the gardener's aid. These are suckers, offsets, stolons, and runners. ( 88. Suckers are ascending branches rising from stems under ground, such" as are produced so abundantly by the Rose, Raspberry, and other plants said to multiply " by the root." If we uncover them, we see at once the great difference between these subterranean branches and real roots. They are only creeping branches under ground. Remarking how the upright shoots from these branches become separate plants, simply by the dying off of the connecting under-ground stems, the gardener expedites the result by cutting them through with his spade. That is, he propagates the plant " by division." 89. Stolons are trailing or reclining branches above ground, which strike root where they touch the soil, and then send up a vigorous shoot, which has roots of its own, and becomes an independent plant when the connecting part dies, as it does after a while. The Currant 4 38 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON 6. and the Gooseberry naturally multiply in this way, as well as by suckers (which we see are just the same thing, only the connecting part is concealed under ground). They must have suggested the operation of layering, or bending down and covering with earth branches which do not naturally make stolons ; and after they have taken root, as they almost always will, the gardener cuts through the connecting stem, and so converts a rooting branch into a sepa- rate plant. 90. Offsets, like those of the Houseleek, are only short stolons, with a crown of leaves at the end. 91. Runners, of which the Strawberry presents the most familiar example, are a long and slender, tendril-like, leafless form of creep- ing branches. Each runner, after having grown to its full length? strikes root from the tip, and fixes it to the ground, then forms a bud there, which develops into a tuft of leaves, and so gives rise to a new plant, which sends out new runners to act in the same way. In this manner a single Strawberry plant will spread over a large space, or produce a great number of plants, in the course of the summer ; — all connected at first by the slender runners ; but these die in the following winter, if not before, and leave the plants as so many separate individuals. 92. Tendrils are branches of a very slender sort, like runners, not destined like them for propagation, and therefore always destitute of buds or leaves, but intended for climbing. Those of the Grape- Vine, of the Virginia Creeper (Fig. 62), and of the Cucumber and FIG. G2. Piece of the stem of Virginia Creeper, bearing a leaf and a tendril. G3. Tips of a tendril, about the natural size, showing the disks by which they hold fast to walls, &,c. LESSON 6.] RUNNERS, TENDRILS, SPINES. 39 Squash tribe are familiar illustrations. The tendril commonly grows straight and outstretched until it reaches some neighboring support, such as a stem, when its apex hooks around it to secure a hold ; then the whole tendril shortens itself by coiling up spirally, and so draws the shoot of the growing plant nearer to the supporting object. "When the Virginia Creeper climbs the side of a building or the smooth bark of a tree, which the tendrils cannot lay hold of in the usual way, their tips expand into a flat disk or sucker (Fig. 62, 63), which adheres very firmly to the wall or bark, enabling the plant to climb over and cover such a surface, as readily as the Ivy does by means of its sucker-like little rootlets. The same result is effected by different organs, in the one case by branches in the form of ten- drils ; in the other, by roots. 93. Tendrils, however, are not always branches ; some are leaves, or parts of leaves, as those of the Pea (Fig. 20). Their nature in each case is to be learned from their position, whether it be that of a leaf or of a branch. In the same way 04. Spines or Thorns sometimes represent leaves, as in the Bar- berry, where their nature is shown by their situation outside of an axillary bud or branch. In other words, here they have a bud in their axil, and are therefore leaves ; so we shall have to mention them in another place. Most commonly spines are stunted and hardened branches, arising from the axils of leaves, as in the Haw- thorn and Pear. A neglected Pear-tree or Plum-tree shows every gradation between ordinary branches and thorns. Thorns sometimes branch, their branches partaking of the same spiny character : in this way those on the trunks of Honey-Locust trees (produced from adventitious buds, 58) become exceedingly complicated and horrid. The thorns on young shoots of the Honey-Locust may appear some- what puzzling at first view ; for they are situated some distance above the axil of the leaf. Here the thorn comes from the upper- most of several supernumerary buds (59). Prickles, such as those of the Rose and Blackberry, must not be confounded with thorns : these have not the nature of branches, and have no connection with the wood ; but are only growths of the bark. When we strip off the bark, the prickles go with it. 95. Still stranger forms of stems and branches than any of these are met with in some tribes of plants, such as Cactuses (Fig. 76). These will be more readily understood after we have considered some of the commoner forms of 40 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON 6. 96. Subterranean Stems and Branches, These are very numerous and various ; but they are commonly overlooked, or else confounded with roots. From their situation they are out of the sight of the superficial observer : but if sought for and examined, they will well repay the student's attention. For the vegetation that is carried on under ground is hardly less varied, and no less interesting and im- portant, than that which meets our view above ground. All their forms may be referred to four principal kinds ; namely, the Rhizo- ma or Rootstock, the Tuber, the Corm, and the Bulb. 97. The Rootstock, or Rhizoma, in its simplest form, is merely a creeping stem or branch (86) growing beneath the surface of the soil, or partly covered by it. Of this kind are the so-called creeping, running, or scaly roots, such as those by which the Mint (Fig. 64), the Scotch Rose, the Couch-grass or Quick-grass, and many other plants, spread so rapidly and widely, " by the root," as it is said. That these are really stems, and not roots, is evident from the way in which they grow; from their consisting of a succession of joints; and from the leaves which they bear on each joint (or node, as the botanist calls the place from which leaves arise), in the form of small scales, just like the lowest ones on the upright stem next the ground. Like other stems, they also produce buds in the axils of these scales, showing the scales to be leaves ; whereas real roots bear neither leaves nor axillary buds. Placed, as they are, in the damp and dark soil, such stems naturally produce roots, just as the creeping stem does where it lies on the surface of the ground ; but the whole appearance of these roots, their downward growth, and their mode of branching, are very different from that of the subter- ranean stem they spring from. '98. It is easy to see why plants with these running rootstocks take such rapid and wide possession of the soil, — often becoming great pests to farmers, — and why they are so hard to get rid of. They are FIG. 64. Rootstocks, or creeping subterranean branches, of the Peppermint. LESSON 6.] SUBTERRANEAN FORMS I ROOTSTOCKS. 41 always perennials (41) ; the subterranean shoots live over the first winter, if not longer, and are provided with vigorous buds at every joint. Some of these buds grow in spring into upright stems, bearing foliage, to elaborate the plant's crude food into nourishment, and at length produce blossoms for reproduction by seed ; while many oth- ers, fed by nourishment supplied from above, form a new generation of subterranean shoots ; and this is repeated over and over in the course of the season or in succeeding years. Meanwhile as the sub- terranean shoots increase in number, the older ones, connecting the series of generations into one body, die off year by year, liberating the already rooted side-branches as so many separate plants ; and so on indefinitely. Cutting these running rootstocks into pieces, therefore, by the hoe or the plough, far from destroying the plant, only accelerates the propagation ; it converts one many-branched plant into a great number of separate individuals. Even if you divide the shoots into as many pieces as there are joints of stem, each piece (Fig. 65) is already a plantlet, with its roots and with a bud in the axil of its scale-like leaf (either latent or apparent), and having prepared nourishment enough in the bit of stem to develop this bud into a leafy stem ; and so a single plant is all the more speedily converted into a multitude. Such plants as the Quick- grass accordingly realize the fable of the Hy- dra ; as fast as one of its many branches is cut 65 off, twice as many, or more, spring up in its stead. Whereas, when the subterranean parts are only roots, cutting away the stem com- pletely destroys the plant, except in the rather rare cases where the root produces adventitious buds (58). 99. The more nourishment rootstocks contain, the more readily do separate portions, furnished with buds, become independent plants. It is to such underground stems, thickened with a large amount of starch, or some similar nourishing matter stored up in their tissue, that the name of rhizoma or rootstock is commonly applied ; — such, for example, as those of the Sweet Flag or Calamus, of Ginger, of Iris or Flower-de-luce (Fig. 133), and of the Solomon's Seal (Fig. 66). 100. The rootstocks of the common sorts of Iris of the gardens usually lie on the surface of the ground, partly uncovered ; and they bear real leaves (Fig. 133), which closely overlap each other ; FIG. 65. A piece of the running rootstock of the Peppermint, with its node or joint, and an axillary bud read}' to grow. 4* 42 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON 6. the joints (i. e. the internodes, or spaces between each leaf) being very short. As the leaves die, year by year, and decay, a scar left in the form of a ring marks the place where each leaf was attached. Instead of leaves, rootstocks buried under ground com- monly bear scales, like those of the Mint (Fig. 64), which are im- perfect leaves. 101. Some rootstocks are marked with large round scars of a different sort, like those of the Solomon's Seal (Fig. 66), which gave this name to the plant, from their looking something like the impres- sion of a seal upon wax. Here the rootstock sends up every spring an herbaceous stalk or stem, which bears the foliage and flowers, and dies in autumn ; and the seal is the circular scar left by the death and separation of the dead stalk from the living rootstock. As but one of these is formed each year, they mark the limits of a year's growth. The bud at the end of the rootstock in the figure, which was taken in summer, will grow the next spring into the stalk of the season, which, dying in autumn, will leave a similar scar, while another bud will be formed farther on, crowning the ever-advancing summit or growing end of the stem. 102. As each year's growth of stem, in all these cases, makes its own roots, it soon becomes independent of the older parts. And after a certain age, a portion dies off behind, every year, about as fast as it increases at the grow- ing end ; — death following life with equal and certain step, with only a narrow interval be- tween. In vigorous plants of Solomon's Seal or Iris, the living rootstock is several inches or a foot in length ; while in the short rootstock of 67 FIG. 6(5. Rootstock of Solomon's Seal, with tho bottom of the stalk of the season, and the bud for tho next year's pnnvth. FIG. 67. The very short rootstock and bud of a Trillium or Birthroot. LESSON 6.] SUBTERRANEAN FORMS I TUBERS. 43 Trillium or Birthroot (Fig. 67) life is reduced to a very narrow span, only an inch or less intervening between death beneath and young life in the strong bud annually renewed at the summit. 103. A Tllbcr is a thickened portion of a rootstock. When slender subterranean branches, like those of the Quick-grass or Mint (Fig. 64), become enlarged at the growing end by the accumulation there of an abundance of solid nourishing matter, tubers are produced, like those of the Nut-grass of the Southern States (which accordingly be- comes a greater pest even than the Quick-grass), and of the Jerusalem Artichoke, and the Potato. The whole formation may be seen at a glance in Figure 68, which represents the subterranean growth of a Potato-plant, and shows the tubers in all their stages, from shoots just beginning to enlarge at the tip, up to fully-formed potatoes. And Fig. 69, — one of the forming tubers moderately magnified, — plainly shows the leaves of this thickening shoot, in the form of little scales. It is under these scales that the eyes appear (Fig. 70) : and these are evidently axillary buds (43). f Xy 104. Let us glance for a moment at the economy or mode of life of the Potato-plant, and similar vegetables, as shown in the mor- FIG, C8. Forming tubers of the Potato. G9.

[LESSON 6. plwloyy of the branches, — that is, in the different forms they appear under, and the purposes they serve. The Potato-plant has three principal forms of branches : — 1. Those that bear ordinary leaves, expanded in the air, to digest what they gather from it and what the roots gather from the soil, and convert it into nourishment. 2. After a while a second set of branches at the summit of the plant bear flowers, which form fruit and seed out of a portion of the nourishment which the leaves have prepared. 3. But a larger part of this nourishment, while in a liquid state, is carried down the stem, into a third sort of branches under ground, and accumulated in the form of starch at their extremities, which become tubers, or deposi- tories of prepared solid food; — just as in the Turnip, Carrot, Dahlia, &c. (Fig. 57-60), it is deposited in the root. The use of the store of food is obvious enough. In the autumn the whole plant dies, except the seeds (if it formed them) and the tubers ; and the latter are left disconnected in the ground. Just as that small portion of nourishing matter which is deposited in the seed (3, and Fig. 34) feeds the embryo when it germinates, so the much larger portion deposited in the tuber nourishes its buds, or eyes, when they likewise grow, the next spring, into new plants. And the great supply enables them to shoot with a greater vigor at the beginning, and to produce a greater amount of vegetation than the seedling plant could do in the same space of time ; which vegetation in turn may prepare and store up, in the course of a few weeks or months, the largest quantity 'of solid nourishing material, in a form most available for food. Taking advantage of this, man has transported the Potato from the cool Andes of South America to other cool cli- mates, and makes it yield him a copious supply of food, especially in countries where the season is too short, or the summer's heat too little, for profitably cultivating the principal grain-plants. 105. All the sorts of subterranean stems or branches distinguished by botanists pass into one another by gradations. We have seen how nearly related the tuber is to the rootstock, and there are many casi'-j in which it is difficult to say which is the proper name to use. So likewise, IOC. Tll3 Corm, OF Solid Blllb, like that of the Indian Turnip and the Crocus (Fig. 71), is just a very short and thick rootstock; as will be seen by comparing Fig. 71 with Fig. G7. Indeed, it grows go very little in length, that it is often much broader than long, as in the Indian Turnip, and the Cyclamen of our greenhouses. Corms LESSON 6.] SUBTERRANEAN FORMS : BULBS. 45 are usually upright, producing buds on their upper surface and roots from the lower. But (as we see in the Crocus here figured) buds may shoot from just above any of the faint cross lines or rings, which are the scars left by the death and decay of the sheathing bases of former leaves. That is, these are axillary buds. In these extraordinary (just as in ordinary) stems, the buds are either axillary or terminal. The whole mode of growth is just the same, only the corm does not increase in length faster than it does in thickness. After a few years some of the buds grow into new corms at the expense of the old one ; the young ones taking the nourishment from the parent, and storing up a large part of it in their own tissue. When exhausted in this way, as well as by flowering, the old corm dies, and its shrivelled and decaying remains may be found at the side of or beneath the present generation, as we see iii the Crocus (Fig. 71). 107. The corm of a Crocus is commonly covered with a thin and dry, scaly or fibrous husk, consisting of the dead remains of the bases of former leaves. When this husk consists of many scales, there is scarcely any distinction left between the corm and 108. The Bulb, This is an extremely short subterranean stem, usually much broader than high, producing roots from underneath, and covered with leaves or the bases of leaves, in the form of thick- ened scales. It is, therefore, the same as a corm, or solid bulb, only it bears an abundance of leaves or scales, which make up the greater part of its bulk. Or we may regard it as a bud, with thick and fleshy scales. Compare a Lily-bulb (Fig. 73) with the strong scaly buds of the Hickory and Horsechestnut (Fig. 48 and 49), and the resemblance will be apparent enough. 109. Bulbs serve the same purpose as tubers, rootstocks, or corms. The main difference is, that in these the store of food for future growth is deposited in the stem ; while in the bulb, the greater part is deposited in the bases of the leaves, changing them into thick scales, which closely overlap or enclose one another, because the stem does not elongate enough to separate them. That the scales FIG. 71. Corm or solid bulb of a Crocus. 72. The same, cut through lengthwise. 46 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON 6. Some of the bulb are the bases of leaves may be seen at once by follow- ing any of the ground-leaves (root-leaves as they are incorrectly call./" ^own to their origin in the bulb. Fig. 75 represents one of them from the White Lily ; the thickened base, which makes a scale, being cut off below, to show its thickness. After having lasted its time and served its purpose as foliage, the green leaf dies, down to the thickened base, which remains as a scale of the bulb. And year after year, as the bulb grows from the centre, to produce the vege- tation and the flowers of the season, the outer scales yield up their store of nourishment for the purpose, and perish. 110. Each scale, being a leaf, may have a bud in its axil, of these buds grow into leafy and flowering stems above ground : others grow into new bulbs, feeding on the parent, and at length destroying it, in the same way that corms do, as just described (10G). 111. When the scales are broad and enwrap all that is within so as to form a succession of coats, one over another, the bulb is said to be tunicated or coated. The Tulip, Hyacinth, Leek, and Onion afford such familiar examples of coated bulbs that no figure is needed. When the scales are narrow and separate, as in the Lily (Fig. 73), the bulb is said to be scaly. 112. BulbletS are small bulbs formed above ground on some plants ; as in the axils of the leaves of the common bulbiferous Lily of the gardens, and often in the flower-clusters of the Leek and Onion. They are plainly nothing but bulbs with thickened scales. They never grow into branches, but detach themselves when 75 full grown, and fall to the ground, to take root there and form jiew plants. 113.

LESSON 6.] CONSOLIDATED FORMS OF VEGETATION. 47 can hardly fail to obtain a good idea of what is meant by morphology in Botany ; and they will be able to apply its simple principles for themselves to all forms of vegetation. They will find it very inter- esting to identify all these various subterranean forms with the com- mon plan of vegetation above ground. There is the same structure, and the same mode of growth in reality, however different in ap- pearance, and however changed the form, to suit particular conditions, or to accomplish particular ends. It is plain to see, already, that the plant is constructed according to a plan, — a very simple one, — which is exhibited by all vegetables, by the extraordinary no less than by the ordinary kinds ; and that the same organ may appear under a great many different shapes, and fulfil very different offices. 114. These extraordinary shapes are not confined to subterra- nean vegetation. They are all repeated in various sorts of fleshy plants ; in the Houseleek, Aloe, Agave (Fig. 82), and in the many and strange shapes which the Cactus family exhibit (Fig. 76) ; shapes which imitate rootstocks, tubers, corms, &c. above ground. All these we may regard as 115. Consolidated Forms of Vegetation, While ordinary plants are constructed on the plan of great spread of surface (131), these are formed on the plan of the least possible amount of surface in proportion to their bulk. The Cereus genus of Cactuses, for ex- ample, consisting of solid columnar trunks (Fig. 76, #), may be likened to rootstocks. A green rind serves the purpose of foliage ; but the surface is as nothing compared with an ordinary leafy plant of the same bulk. Compare, for instance, the largest Cactus known, the Giant Cereus of the Gila River (Fig. 76, in the background), which rises to the height of fifty or sixty feet, with a common leafy tree of the same height, such as that in Fig. 54, and estimate how vastly greater, even without the foliage, the surface of the latter is than that of the former. Compare, in the same view, an Opuntia or Prickly-Pear Cactus, its stem and branches formed of a succes- sion of thick and flattened joints (Fig. 76, «), which may be likened to tubers, or an Epiphyllum (d), with shorter and flatter joints, with an ordinary leafy shrub or herb of equal size. And finally, in Melon-Cactuses or Echinocactus (e), with their globular or bulb-like shapes, we have plants in the compactest shape ; their spherical fig- ure being such as to expose the least possible amount of its bulk to the air. 116. These consolidated plants are evidently adapted and designed 48 MORPHOLOGY OF STEMS AND BRANCHES. [LESSON 6. for very dry regions ; and in such only are they found. Similarly, bulbous and corm-bearing plants, and the like, are examples of a form of vegetation which in the growing season may expand a large surface to the air and light, while during the period of rest the living vegetable is reduced to a globe, or solid form of the least possible surface ; and this is protected by its outer coats of dead and dry scales, as well as by its situation under ground. Such plants exhibit another and very similar adaptation to a season of drought. And they mainly belong to countries (such as Southern Africa, and parts of the interior of Oregon and California) which have a long hot season during which little or no rain falls, when, their stalks and foliage above and their roots beneath being early cut off by drought, the plants rest securely in their compact bulbs, filled with nourishment, and retaining their moisture with great tenacity, until the rainy season comes round. Then they shoot forth leaves and flowers with wonderful rapidity, and what was perhaps a desert of arid sand becomes green with foliage and gay with blossoms, almost in a day. This will be more perfectly understood when the nature and use of foliage have been more fully considered. (Fig. 76 represents several forms of Cactus vegetation.) LESSON 7.J MORPHOLOGY OF LEAVES. 49 LESSON VII. MORPHOLOGY OF LEAVES. 117. IN describing the subterranean forms of the stem, we have been led to notice already some of the remarkable forms under which leaves occur ; namely, as scales, sometimes small and thin, as those of the rootstocks of the Quick-grass, or the Mint (Fig. 64), sometimes large and thick, as those of bulbs (Fig. 73 - 75), where they are commonly larger than the stem they belong to. We have seen, too, in the second Lesson, the seed-leaves (or cotyledons) in forms as unlike foliage as possible ; and in the third Lesson we have spoken of bud-scales as a sort of leaves. So that the botanist recog- nizes the leaf under other forms than that of foliage. 118. We may call foliage the natural form of leaves, and look upon the other sorts as special forms, — as transformed leaves: by this term meaning only that what would have been ordinary leaves under other circumstances (as, for instance, those on shoots of Mint, Fig. 64, had these grown upright in the air, instead of creeping under ground) are developed in special forms to serve some particular purpose. For the Great Author of Nature, having designed plants upon one simple plan, just adapts this plan to all cases. So, when- ever any special purpose is to be accomplished, no new instruments or organs are created for it, but one of the three general organs of the vegetable, root, stem, or leaf, is made to serve the purpose, and- is adapted to it by taking some peculiar form. 119. It is the study of the varied forms under this view that con- stitutes Morphology (61), and gives to this part of Botany such great interest. We have already seen stems and roots under a great variety of forms. But leaves appear under more various and widely different forms, and answer a greater variety of purposes, than do both the other organs of the plant put together. We have to con- sider, then, leaves as foliage, and leaves as something else than foliage. As we have just been noticing cases of leaves that are not foliager we may consider these first, and enumerate the principal kinds. 120. Leaves as Depositories of Food, Of these we have had plenty of Instances in the seed-leaves, such as those of the Almond, Apple- 50 MORPHOLOGY OF LEAVES. [LESSON 7. seed (Fig. 11), Beech (Fig. 13-15), the Bean and Pea (Fig. 16- 20), the Oak (Fig. 21, 22), and Horsechestnut (Fig. 23, 24) ; where the food upon which the plantlet feeds when it springs from the seed is stored up in its cotyledons or first leaves. And we have noticed how very unlike foliage such leaves are. Yet in some cases, as in the Pumpkin (Fig. 10), they actually grow into green leaves as they get rid of their burden. 121. Bulb-Scales (Fig. 73-75) of- fer another instance, which we were considering at the close of the last Lesson. Here a part of the nourish- ment prepared in the foliage of one year is stored up in the scales, or subterranean thickened leaves, for the early growth and flowering of the next year ; and this enables the flowers to appear before the leaves, or as soon as they do ; as in Hyacinths, Snow- drops, and many bulbous plants. 122. Leaves as Bud-scales, £c, True to its nature, the stem produces leaves even under ground, where they cannot serve as foliage, and where often, as on rootstocks and tubers (97 - 103), they are not of any use that wre know of. In such cases they usually appear as thin scales. So the first leaves of the stems of herbs, as they sprout from the ground, are generally mere scales, such as those of an Asparagus shoot ; and such are the first leaves on the stem of the seedling Oak (Fig. 22) and the Pea (Fig. 20). Similar scales, however, often serve an im- portant purpose ; as when they form the covering of buds, where they protect the tender parts within (44). That bud-scales are PIG. 77. Leaves of a dnveloping bud of the Low Sweet Buckeye (jEsculus parviflora), showing a nearly complete set of gradations from a scale to a compound leaf of five leaflets. LESSON 7.] SPINES, TENDRILS, AND PITCHERS. 51 leaves is plainly shown, in many cases, by the gradual transition between them and the first foliage of the shoot. The Common Lilac and the Shell-bark Hickory are good instances of the sort. But the best illustration is fur- nished by the Low Sweet Buckeye of the Southern States, which is often cultivated as an ornamental shrub. From one and the same growing bud we may often find all the grada- tions which are shown in Fig. 77. 123. Leaves as Spines occur in several plants. The most familiar instance is that of the Com- mon Barberry. In almost any summer shoot, most of the gradations may be seen between the ordinary leaves, with sharp bristly teeth, and leaves which are reduced to a branching spine or thorn, as shown in Fig. 78. The fact that the spines of the Barberry produce a leaf-bud in their axil also proves them to be leaves. 124. Leaves as Tendrils are to be seen in the Pea and the Vetch (Fig. 20, 127), where the upper part of each leaf becomes a tendril, which the plant uses to climb by ; and in one kind of Vetch the whole leaf is such a tendril. 125. Leaves as Pitchers, or hollow tubes, are familiar to us in the common Pitcher- plant or Side-saddle Flower (Sarracenia, Fig. 79) of our bogs. These pitchers are generally half-full of water, in which flies and other insects are drowned, often in such numbers as to make a rich manure for the plant, no doubt ; though we can hardly imagine this to be the design of the pitcher. Nor do we per- ceive here any need of a contrivance to hold water, since the roots of these plants are always well supplied by the wet bogs where they grow. FIG. 78. Summer shoot of Barberry, showing the transition of leaves into spinea. FIG. 79. Leaf of Sarracenia purpurea, entire, and another with the upper part cut off. 52 MORPHOLOGY OF LEAVES. [LESSON 7. 126. Leaves as Fly-traps, Insects are caught in another way, and more expertly, by the most extraordinary of all the plants of this country, the Dionam or Venus's Fly- trap, which grows in the sandy bogs around Wilmington, North Carolina. Here (Fig. 81) each leaf bears at its summit an appendage which opens and shuts, in shape something like a steel- trap, and operating much like one. For when open, as it commonly is when the sun shines, no sooner does a fly alight on its surface, and brush against any one of the several long bristles that grow there, than the trap suddenly closes, often capturing the intruder, pressing it all the harder for its struggles, and com- monly depriving it of life. If the fly escapes, the trap soon slowly opens, and is ready for another capture. When retained, the insect is after a time moistened by a secretion from minute glands of the inner sur- face, and is apparently digested ! How such and various other movements are made by plants, — some as quick as in this case, others very slow, but equally wonderful, — must be considered in a future Lesson. 127. kaves serving both Ordinary and Special Purposes, Let us now remark, that the same leaf frequently answers its gen- eral purpose, as foliage, and some special purpose besides. For example, in the Dio- nasa, the lower part of the leaf, and prob- ably the whole of it, acts as foliage, while the appendage serves its mysterious purpose as a fly-catcher. In the Pea and Vetch (Fig. 20, 127), the lower part of the leaf is foliage, the upper a tendril. In the Pitcher-plants of the Indian Archipelago (Nepenthes, Fig. 80) which are not rare in conserva- tories, the lower part of the leaf is expanded and acts as foliage ; FIG. 80. Leaf of Nepenthes: leaf, tendril, and pitcher combined. FIG. 81. Leaves of Dionaea : the trap in one of them open, in the others closed. LESSON 7.] THICKENED AND FLESHY LEAVES. 53 farther on, it is contracted into a tendril, enabling the plant to climb ; the end of this tendril is then expanded into a pitcher, of five or six inches in length, and on the end of this is a lid, which exactly closes the mouth of the pitcher until after it is full grown, when the lid opens by a hinge ! But the whole is only one leaf. 128. So in the root-leaves of the Tulip or the Lily (Fig. 75), while the green leaf is preparing nourishment throughout the grow- ing season, its base under ground is thickened into a reservoir for storing up a good part of the nourishment for next year's use. 129. Finally, the whole leaf often serves both as foliage, to pre- pare nourishment, and as a depository to store it up. This takes place in all fleshy-leaved plants, such as the Houseleek, the Ice- plant, and various sorts of Mesembryanthemum, in the Live-for-ever of the gardens to some extent, and very strikingly in the Aloe, and in the Century-plant. In the latter it is only the green surface of these large and thick leaves (of three to five feet in length on a strong plant, and often three to six inches thick near the base) which acts as foliage ; the whole interior is white, like the interior of a potato, and almost as heavily loaded with starch and other nourish- ing matter. (Fig. 82 represents a young Century-plant, Agave Americana.) 5* 54 MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 8. LESSON VIII. MORPHOLOGY OF LEAVES AS FOLIAGE. 130. HAVING in the last Lesson glanced at some of the special or extraordinary forms and uses of leaves, we now return to leaves in their ordinary condition, namely, as foliage. We regard this as the natural state of leaves. For although they may be turned to account in other and very various ways, as we have just seen, still their proper office in vegetation is to serve as foliage. In this view we may regard 131. Leaves as a Contrivance for Increasing the Surface of that large part of the plant which is exposed to the light and the air. This is shown by their expanded form, and ordinarily slight thickness in comparison with their length and breath. While a Melon-Cactus (115, Fig. 76) is a striking example of a plant with the least pos- sible amount of surface for its bulk, a repeatedly branching leafy herb or tree presents the largest possible extent of surface to the air. The actual amount of surface presented by a tree in full leaf is much larger than one would be apt to suppose. Thus, the Wash- ington Elm at Cambridge — a tree of no extraordinary size — was some years ago estimated to produce a crop of seven millions of leaves, exposing a surface of 200,000 square feet, or about five acres, of foliage. 132. What is done by the foliage we shall have to explain in another place. Under the present head we are to consider ordinary leaves as to their parts and their shapes. 1-J3. The Parts Of the Leaf, The principal part of a leaf is the blade, or expanded portion, one face of which naturally looks toward the sky, the other towards the earth. The blade is often raised on a stalk of its own, and on each side of the stalk at its base there is sometimes an appendage called a stipule. A complete leaf, there- fore consists of a blade (Fig. 83, b), a foot-stalk or leaf -stalk, called the petiole (/>), and a pair of stipules (st). See also Fig. 136. 134. It is the blade which we are now to describe. This, as being the essential and conspicuous part, we generally regard as the leaf: and it is only when we have to particularize, that we speak of the blade, or lamina, of the leaf. LESSON 8.] THEIR VENATION. 135. Without here entering upon the subject of the anatomy of the leaf, we may remark, that leaves consist of two sorts of mate- rial, viz.: 1. the green pulp, or parenchyma; and 2. the fibrous framework, or skeleton, which extends throughout the soft green pulp and supports it, giving the leaf a strength and firmness which it would not otherwise possess. Besides, the whole surface is cov- ered with a transparent skin, called the epidermis, like that which covers the surface of the shoots, &c. 136. The framework consists of wood, — a fibrous and tough material which runs from the stem through the leaf-stalk, when there is one, in the form of parallel threads or bundles of fibres ; and in the blade these spread out in a horizontal direction, to form the ribs and veins of the leaf. The stout main branches of the framework (like those in Fig. 50) are called the ribs. When there is only one, as in Fig. 83, &c., or a middle one decid- edly larger than the rest, it is called the midrib. The smaller divisions are termed veins ; and their still smaller subdivisions, veinlets. 137. The latter subdivide again and again, until they become so fine that they are invisible to the naked eye. The fibres of which they are composed are hollow ; forming tubes by which the sap is brought into the leaves and carried to every part. The arrangement of the framework in the blade is termed the \|.38. Venation, or mode of veining. This corresponds so complete- ly with the general shape of the leaf, and with the kind of division when the blade is divided or lobed, that the readiest way to study and arrange the forms of leaves is first to consider their veining. 139. Various as it appears in different leaves, the veining is all reducible to two principal kinds ; namely, the parallel-veined and the netted-veined. 140. In netted-veined (also called reticulated) leaves, the veins branch off from the main rib or ribs, divide into finer and finer FIG. S3. Leaf of the Quince: b, blade ; p, petiole ; st, stipules. 5G MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 8. veinlets, and the branches unite with each other to form meshes of network. That is, they anastomose, as anatomists say of the veins and arteries of the body. The Quince-leaf, in Fig. 83, shows this kind of veining in a leaf with a single rib. The Maple, Basswood, and Buttonwood (Fig. 50) show it in leaves of several ribs. 141. In parallel-veined leaves, the whole framework consists of slender ribs or veins, which run parallel with each other, or nearly so, from the base to the point of the leaf, not dividing and sub- dividing, nor forming meshes, except by very minute cross-veinlets. The leaf of any grass, or that of the Lily of the Valley (Fig. 84) will furnish a good illustration. 142. Such simple, parallel veins Linnaeus, to distinguish them, called nerves, and parallel-veined leaves are still commonly called nerved leaves ; while those of the other kind are said to be veined; — terms which it is conven- ient to use, although these " nerves " and " veins " are all the same thing, and have no likeness to the nerves of animals. 143. Netted-veined leaves belong to plants which have a pair of seed-leaves or cotyledons, such as the Maple (Fig. 1 -7), Beech (Fig. 15), Pea and Bean (Fig. 18, 20), and most of the illustra- tions in the first and second Lessons. While parallel-veined or nerved leaves belong to plants with one cotyledon or true seed-leaf; such as the Iris (Fig. 134) and Indian Corn (Fig. 42). So that a mere glance at the leaves of the tree or herb enables one to tell what the structure of the embryo is, and to refer the plant to one or the other of these two grand classes, — which is a great convenience. For generally when plants differ from each other in some one important respect, they differ correspondingly in other respects as well. 144. Parallel-veined leaves are of two sorts ; one kind, and the commonest, having the ribs or nerves all running from the base to the point of the leaf, as in the examples already given ; while in another kind they run from a midrib to the margin ; as in the com- FIG. 84. A (parallel-veined) leaf of the Lily of the Valley. LESSON 8.] THEIR FORMS AS TO GENERAL OUTLINE. 57 mon Pickerel-weed of our ponds, in the Banana (Fig. 47), and many similar plants of warm climates. 145. Netted-veined leaves are also of two sorts, as is shown in the examples already referred to. In one case the veins all rise from a single rib (the midrib), as in Fig. 83. Such leaves are called feather-veined or pinnately-veined ; both terms meaning the same thing, namely, that the veins are arranged on the sides of the rib like the plume of a feather on each side of the shaft. 146. In the other case (as in the Button wood, Fig. 50, Maple, &c.), the veins branch off from three, five, seven, or nine ribs, which spread from the top of the leaf-stalk, and run through the blade like the toes of a web-footed bird. Hence these are said to be palmately or digitately veined, or (since the ribs diverge like rays from a centre) radiate-veined. 147. Since the general outline of leaves accords with the frame- work or skeleton, it is plain that feather-veined leaves will incline to elongated shapes, or at least will be longer than broad ; while in radiate-veined leaves more rounded forms are to be expected. A glance at the following figures shows this. Whether we consider the veins of the leaf to be adapted to the shape of the blade, or the green pulp to be moulded to the framework, is not very material. Either way, the outline of each leaf corresponds with the mode of spreading, the extent, and the relative length of the veins. Thus, in oblong or elliptical leaves of the feather-veined sort (Fig. 87, 88), the principal veins are nearly equal in length ; while in ovate and heart-shaped leaves (Fig. 89, 90), those below the middle are longest; and in leaves which widen upwards (Fig. 91-94), the veins above the middle are longer than the others. 148. Let us pass on, without particular reference to the kind of veining, to enumerate the principal 149. Forms of Leaves as to General Outline, It is necessary to give names to the principal shapes, and to define them rather precisely, since they afford the easiest marks for distinguishing species. The same terms are used for all other flattened parts as well, such as the petals of the flowers ; so that they make up a great part of the descriptive language of Botany. We do not mention the names of common plants which exhibit these various shapes. It will be a good exercise for young students to look them up and apply them. 150. Beginning with the narrower and proceeding to the broadest forms, a leaf is said to be 58 MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 8. Linear (Fig. 85), when narrow, several times longer than wide, and of the same breadth throughout. Lanceolate, or lance-shaped, when several times longer than wide, and tapering upwards (Fig. 8G), or both upwards and downwards. Oblong (Fig. 87), when nearly twice or thrice as long as broad. Elliptical (Fig. 88) is oblong with a flowing outline, the two ends alike in width. Oval is the same as broadly elliptical, or elliptical with the breadth considerably more than half the len'gth. Ovate (Fig. 89), when the outline is like a section of a hen's-egg lengthwise, the broader end downward. Orbicular, or rotund (Fig. 102), circular in outline, or nearly so. 151. When the leaf tapers towards the base, instead of upwards, it may be OUanceolate (Fig. 91), which is lance-shaped, with the more tapering end downwards ; Spatulate (Fig. 92), round- ed above and long and narrow below, like a spatula ; Obovate (Fig. 93), or in- versely ovate, that is, ovate with the narrower end down ; or Cuneate, or cuneiform, that is, wedge-shaped (Fig. 94), broad above and tapering by straight lines to an acute angle at the base. 152. As to lllC Base, its shape characterizes several forms, such as Cordate, or heart-shaped (Fig. 90, 99, 8), when a leaf of an ovate form, or something like it, has the outline of its rounded base turned in (forming a notch or sinus) where the stalk is attached. Renifovm, or kidney-shaped (Fig. 100), like the last, only rounder and broader than long. FIG. 85-90. Various forma of feather-veined leaves. FIG, 91.

LESSON 8.] THEIR PARTICULAR FORMS. 59 Auriculate, or eared, having a pair of small and blunt projections, or ears, at the base, as in one species of Magnolia (Fig. 96). Sagittate, or arrow-shaped, where such ears are pointed and turned downwards, while the main body of the blade tapers upwards to a point, as in the com- mon Sagittaria or Ar- row-head, and in the Arrow-leaved Polygo- num (Fig. 95). Hastate, or halberd- shaped, when such lobes at the base point outwards, giving the leaf the shape of the halberd of the olden time, as in another Polygonum (Fig. 97). Peltate, or shield-shaped, (Fig. 102,) is the name applied to a curious modification of the leaf, commonly of a rounded form, where the footstalk is attached to the lower surface, instead of the base, and 102 therefore is naturally likened to a shield borne by the outstretched arm. The common Watershield, the Nelumbium, and the White Water-lily, and also the Mandrake, exhibit this sort of leaf. On comparing the shield-shaped leaf of the common Marsh Pennywort 'Fig. 102) with that of another common species (Fig. 101), we see at once what this peculiarity means. A shield-shaped leaf is like a FIG. 95. Sagittate, 96. auriculate, 97. halberd-shaped, loaves. FIG. 98 - 102. Various forms of radiate-veined leaves. GO MORPHOLOGY OF LEAVES AS FOLIAGE.

Acuminate, pointed, or taper-pointed, when the summit is more or less prolonged into a narrowed or tapering point, as in Fig. 97. Acute, when ending in an acute angle or not prolonged point, as in Fig. 104, 98, 95, &c. Obtuse, when with a blunt or rounded point, as in Fig. 105, 89, &c. Truncate, with the end as if cut off square, as in Fig. 106, 94. Hetuse, with the rounded summit slightly indented, forming a very shallow notch, as in Fig. 107. Emarginate, or notched, indented at the end more decidedly, as in Fig. 108. Obcordate, that is, inversely heart-shaped, where an obovate leaf is more deeply notched at the end (Fig. 109), as in White Clover and Wood-sorrel ; so as to resemble a cordate leaf (Fig. 99) inverted. Cuspidate, tipped with a sharp and rigid point ; as in Fig. 110. Mucronate, abruptly tipped with a small and short point, like a projection of the midrib ; as in Fig. 111. Aristate, awn-pointed, and bristle-pointed, are terms used when this mucronate point is extended into a longer bristle-form or other slender appendage. The first six of these terms can be applied to the lower as well as to the upper end of a leaf or other organ. The others belong to the apex only. FIG. 103 - 111. Forms of the apex of leaves. LESSON 9.] SIMPLE AND COMPOUND LEASES. 61 LESSON IX. MORPHOLOGY OF LEAVES AS FOLIAGE. SIMPLE AND COM- POUND LEAVES, STIPULES, ETC. 154. IN the foregoing Lesson leaves have been treated of in their simplest form, namely, as consisting of a single blade. But in many cases the leaf is divided into a number of separate blades. That is, 155. Leaves are either Simple or Compound, They are sdd to be simple, when the blade is all of one piece : they are compound, when the blade consists of two or more separate pieces, borne upon a common leaf-stalk. And between these two kinds every interme- diate gradation is to be met with. This will appear as we proceed to notice the principal 15G. Forms of Leaves as to particular Outline or degree of division. In this respect, leaves are said to be Entire, when their general outline is completely filled out, so that the margin is an even line, without any teeth or notches ; as in Fig. 83, 84, 100, &c. Serrate, or saw-toothed, when the margin only is cut into sharp teeth, like those of a saw, and pointing forwards; as in Fig. 112; also 90, &c. 112 113 114 115 116 117 Dentate, or toothed, when such teeth point outwards, instead of forwards ; as in Fig. 113. FIG. 112 - 117. Kinds of margin of leares. a 62 MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 9. Crenate, or scalloped, when the teeth are broad and rounded ; as in Fig. 114, 101. Repand, undulate, or wavy, when the margin of the leaf forms a wavy line, bending slightly inwards and outwards in succession ; as in Fig. 115. Sinuate, when the margin is more strongly sinuous, or turned inwards and outwards, as in Fig. 116. Incised, cut, or jagged, when the margin is cut into sharp, deep, and irregular teeth or incisions, as in Fig. 117. 157. When leaves are more deeply cut, and with a definite number of incisions, they are said, as a general term, to be lobed ; the parts being called lobes. Their number is expressed by the phrase two- lobed, three-lobed, Jive-lobed, many-lobed, &c., as the case may be. When the depth and character of the lobing needs to be more par- ticularly specified, — as is often the case, — the following terms are employed, viz. : Lobed, when the incisions do not extend deeper than about half- way between the margin and the centre of the blade, if so far, and are more or less rounded ; as in the leaves of the Post-Oak, Fig. 118, and the Hepatica, Fig. 122. Cleft, when the incisions extend half-way down or more, and especially when they are sharp, as in Fig. 119, 123. And the phrases two-cleft, or, in the Latin form, bifid ; three-cleft, or trijid ; four-cleft, or quadrifid ; jive-cleft, or quinquefid, &c. ; or many-cleft, in the Latin form multifid, — express the number of the segments, or portions. ^ Parted, when the incisions are still deeper, but yet do not quite reach to the midrib or the base of the blade ; as in Fig. 120, 124. And the terms two-parted, three-parted, &c. express the number of such divisions. Divided, when the incisions extend quite to the midrib, as in the lower part of Fig. 121 ; or to the leaf-stalk, as in Fig. 125 ; which makes the leaf compound. Here, using the Latin form, the leaf is said to be bisected, trisected (Fig. 125), &c., to express the number of the divisions. 158. In this way the degree of division is described. We may likewise express the mode of division. The notches or incisions, being places where the green pulp of the blade has not wholly filled up the framework, correspond with the veining ; as we perceive on comparing the figures 118 to 121 with figures 122 to 125. The LESSON 9.] LOBED OR DIVIDED LEAVES. 63 upper row of figures consists of feather-veined, or, in Latin form, p innately-veined leaves (145) ; the lower row, of radiate-veined or palmately-veined leaves (146). 118 123 124 125 159. In the upper row the incisions all point towards the midrib, from which the main veins arise, the incisions (or sinuses) being between the main veins. That is, being pinnately veined, such lea\7es are pinnately lobed (Fig. 118), pinnately cleft, or pinnatijid (Fig. 119), pinnately parted (Fig. 120), or pinnately divided (Fig. 121), according to the depth of the incisions, as~just defined. 160. In the lower row of figures, as the main veins or ribs all proceed from the base of the blade or the summit of the leaf-stalk, so the incisions all point in that direction. That is, palmately-vemed leaves are palmately lobed (Fig. 122), palmately cleft (Fig. 123), palmately parted (Fig. 124), or palmately divided (Fig. 125). Some- times, instead of palmately, we say digitately cleft, &c., which means just the same. 161. To be still more particular, the number of the lobes, &c. may come into the phrase. Thus, Fig. 122 is a palmately three- lobed ; Fig. 123, a palmately three-cleft ; Fig. 124, & palmately three- parted ; Fig. 125, a palmately three-divided, or trisected, leaf. The FIG. 118-121.

Sugar-Maple and the Buttonwood (Fig. 50) have palmately Jive- lobed leaves ; the Soft White-Maple palmatcly five-parted leaves; and so on. And in the other sort, the Post-Oak has pinnately seven- to ninc-lobed leaves ; the Red-Oak commonly has pinnately seven- to nine-cleft leaves, &c., &c. 1G2. The divisions, lobes, &c. may themselves be entire (without teeth or notches, 156), as in Fig. 118, 122, &c. : or serrate (Fig. 124), or otherwise toothed or incised (Fig. 121 ); or else lobed, cleft, parted, &c. : in the latter cases making twice pinnalifid, twice pal- matcly or pinnately lobed, parted, or divided leaves, &c. From these illustrations, the student will perceive the plan by which the bota- nist, in two or three words, may describe any one of the almost endlessly diversified shapes of leaves, so as to convey a perfectly clear and definite idea of it. 163. Compound LeaTCS, These, as already stated (155), do not differ iri any absolute way from the divided form of simple leaves. A compound leaf is one which has its blade in two or more entirely separate parts, each usually with a stalklet of its own : and the stalk- let is often jointed (or articulated) with the main leaf-stalk, just as this is jointed with the stem. "When this is the case, there is no doubt that the leaf is compound. But when the pieces have no stalklels, and are not jointed with the main leaf-stalk, the leaf may be considered either as simple and divided, or compound, according to the circumstances. FIO. 12G. Pinnate with an odd leaflet, or odd-pinnate. 127. Pinnate with a tendril 128. Abruptly pinnate leaf. V ; LESSON 9.] COMPOUND LEAVES. 63 164. The separate pieces or little blades of a compound leaf are called leaflets. 165. Compound leaves are of two principal kinds, namely, the pinnate and the palmate ; answering to the two modes of veining in reticulated leaves (145- 147), and to the two sorts of lobed or di- vided leaves (158, 159). 166. Pinnate leaves are those in which the leaflets are arranged on the sides of a main leaf-stalk ; as in Fig. 126 — 128. They answer to the feather-veined (i. e. pinnately-veined) simple leaf; as will be seen at once, on comparing Fig. 126 with the figures 118 to 121. The leaflets of the former answer to the lobes or divisions of the latter ; and the continuation of the petiole, along which the leaflets are arranged, answers to the midrib of the simple leaf. 167. Three sorts of pinnate leaves are here given. Fig. 126 is pinnate with an odd or end leaflet, as in the Common Locust and the Ash. Fig. 127 is pinnate with a tendril at the end, in place of the odd leaflet, as in the Vetches and the Pea. Fig. 128 is abruptly pinnate, having a pair of leaflets at the end, like the rest of the leaf- lets ; as in the Honey-Locust. 1G8. Palmate (also named digitate) leaves are those in which the leaflets are all borne on the very tip of the leaf-stalk, as in the Lupine, the Common Clover (Fig. 136), the Virginia Creeper (Fig. 62), and the Horsechcstnut and Buckeye (Fig. 129). They answer to the radiate-veined or palmately- veined simple leaf; as is seen by comparing Fig. 136 with the figures 122 to 125. That is, the Clover- leaf of three leaflets is the same as Tpalmately three-ribbed leaf cut ito three separate leaflets. And such a simple five-lobed leaf as that of the Sugar-Maple, if more cut, so as to separate the parts, would pro- duce a palmate leaf of five leaflets, like that of the Horsechestnut or Buckeye (Fig. 129). 169. Either sort of compound leaf may have any number of leaf- lets ; though palmate leaves cannot well have a great many, since they are all crowded together on the end of the main leaf-stalk. FIG. 129. Palmate leaf of five leaflets, of the Sweet Buckeye. 6* G6 MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 9. Some Lupines have nine or eleven ; the Horsechestnut has seven, the Sweet Buckeye more commonly five, the Clover three. A pin- nate leaf often has only seven or five leaflets, as in the Wild Bean or Groundnut ; and in the Common Bean it has only three ; in some rarer cases only two ; in the Orange and Lemon only one! The joint at the place where the leaflet is united with the petiole alone distinguishes this last case from a simple leaf.* 170. The leaflets of a com- pound leaf may be either entire (as in Fig. 126-128), or ser- rate, or lobed, cleft, parted, &c. : in fact, they may pre- sent all the variations of simple leaves, and the same terms equally apply to them. 171. When this division is carried so far as to separate what would be one leaflet into two, three, or several, the leaf becomes doubly or twice com- pound, either pinnately orpal- 130 mately, as the case may be. For example, while some of the leaves of the Honey-Locust are simply pinnate, that is, once pinnate, as in Fig. 128, the greater part * When the botanist, in describing leaves, wishes to express the number of leaflets, he may use terms like these : — Unifdiolate, for a compound leaf of a single leaflet; from the Latin unum,ono, saulfuliolum, leaflet. BiJbUcbte, of two leaflets, from the Latin Us, twice, nmlfolidum, leaflet. Trifollolate (or ternate), of three leaflets, as the Clover; and so on. When he would express in one phrase both the number of leaflets and the way the leaf is compound, he writes : — ruhnnli-ly llfullolale, Irlfoliolate, plurifoliolate (of several leaflets), £e., or else Pinnnlrh/ It-, trl-, quailrt-, or pluri-folidate (that is, of two, three, four, five, or several leaflets), as the case may be. FIG. 130. A twico-pinnato (abruptly) leaf of the Hon^v-Locust LESSON 9.J PERFOLIATE LEAVES, ETC. C7 are bipinnate, i. e. twice pinnate, as in Fig. 130. If these leaflets were again divided in the same way, the leaf would become thrice pinnate, or tripinnate, as in many Acacias. (^The first divisions are called pinnae ; the others, pinnules ; and the last, or little blades, leaflets. 172." So the palmate leaf, if again compounded in the same way, becomes twice palmate, or, as we say when the divisions are in threes, twice ternate (in Latin form Alternate) ; if a third time com- pounded, thrice ternate or triternate. But if the division goes still further, or if the degree is variable, we simply say that the leaf is decompound ; either palmately or pinnately so, as the case may be. Thus, Fig. 138 represents a four times ternately compound, in other words a ternately decompound, leaf of our common Meadow Rue. 173. So exceedingly various are the kinds and shapes of leaves, that we have not yet exhausted the subject. "We have, however, mentioned the principal terms used in describing them. Many others will be found in the glossary at the end of the volume. Some peculiar sorts of leaves remain to be noticed, which the student might not well understand without some explanation ; such as 174. Perfoliate Leaves. A common and simple case of this sort is found in two species of Uvularia or Bellwort, where the stem appears to run through the blade of the leaf, near one end. If we look at this plant in summer, after all the leaves are formed, we may see the meaning of this at a glance. For then we often find upon the same stem such a series of leaves as is given in Fig. 131 : the low- er leaves are perfoliate, those next above less so ; then some (the fourth and fifth) rith merely a heart-shaped clasping base, and finally one that is merely sessile. The leaf, we perceive, becomes perfoliate by the union of the edges of the base with each other around the stem ; just as the shield-shaped leaf, Fig. 102, comes from the union of the edges of the base of such a leaf as Fig. 101. Of the same sort are the upper leaves of most of FIG. 131. Leaves of Uvularia (Bellwort) ; the lower ones perfoliate, the others merely clasping, or the uppermost only sessile. 68 MORPHOLOGY OF LEAVES AS FOLIAGE. [LESSON 9. the true Honeysuckles (Fig. 132) : but here it is a pair of oppo- site leaves, with their contiguous broad bases grown together, which makes what seems to be one round leaf, with the stem running through its centre. This is seen to be the case, by comparing together the upper and the lowest leaves of the same branch. Leaves of this sort are said to be connate-per foliate. 175. Equitant Leaves. While ordinary leaves spread horizontally, and present one face to the sky and the other to the earth, there are some that present their tip to the sky, and their faces right and left to the horizon. Among these are the equitant leaves of the Iris or Flower-de-Luce. On careful inspection we shall find that each leaf was formed folded together length- wise, so that what would be the upper surface is within, and all grown together, ex- cept next the bottom, where each leaf covers the next younger one. It was from their strad- dling over each other, like a man on horseback (as is seen in the cross-section, Fig. 134), that Linnaeus, with his lively fancy, called these equitant leaves. 176. Leaves with no distinction of Petiole and Blade, The leaves of Iris just mentioned show one form of tliis. The flat but narrow leaves of Jonquils, Daffodils, and the like, are other in- stances. Needle-shaped leaves, like those of the Pine (Fig. 140), Larch (Fig. 139), and Spruce, and the awl-shaped as well as the scale-shaped leaves of Junipers, Red Ce- FIG. 132.

LESSON 9.] PHILLODIA, STIPULES, ETC. 69 dar, and Arbor- Vitae (Fig. 135), are different examples. These last are leaves serving for foliage, but having as little spread of surface as possible. They make up for this, however, by their immense numbers. 177. Sometimes the petiole expands and flattens, and takes the place of the blade ; as in numerous New Holland Acacias, some of which are now common in greenhouses. Such counterfeit blades are called phyllodia, — meaning leaf-like bodies. They may be known from true blades by their standing edgewise, their margins being directed upwards and downwards ; while in true blades the faces look upwards and downwards ; excepting in equitant leaves, as al- ready explained, and in those which are turned edgewise by a twist, such as those of the Callis- temon or Bottle-brush Flower of our greenhouses, and other Dry Myrtles of New Holland, &c. 178. Stipules, the pair of appendages which is found at the base of the peti- ole in many leaves (133), should also be considered in respect to their very varied forms and appearances. More commonly they appear like little blades, on each side of the leaf-stalk, as in the Quince (Fig. 83), and more strikingly in the Hawthorn and in the Pea. Here they remain as long as the rest of the leaf, and serve for the same purpose as the blade. Very commonly they serve for bud-scales, and fall off when the leaves expand, as in the Fig-tree, and the Magnolia (where they are large and conspicuous), or soon FIG. 135.

Li the Pea the stipules make a very conspicuous part of the leaf; while in the Bean they are quite small ; and in the Locust they are reduced to bristles or prickles. Sometimes the stipules are separate and distinct (Fig. 83) : often they are united with the base of the leaf-stalk, as in the Rose and the Clover (Fig. 136) : and sometimes they grow together by both margins, so as to form a sheath around the stem, above the leaf, as in the Buttonwood, the Dock, and almost all the plants of the Polygonum Family (Fig. 137). 179. The sheaths of Grasses bear the blade on their summit, and therefore represent a form of the petiole. The small and thin ap- pendage which is commonly found at the top of the sheath (called a ligule) here answers to the stipule. FIG. 138. Ternately-decompouiN} leaf of Meadow Rue (Thalictrum Cornuti). LESSON 10.] ARRANGEMENT OF LEAVES. 71 LESSON X. THE ARRANGEMENT OF LEAVES. 180. UNDER this head we may consider, — 1. the arrangement of leaves on the stem, or what is sometimes called PHYLLOTAXY (from two Greek words meaning leaf-order) ; and 2. the ways in which they are packed together in the bud, or their VERNATION (the word meaning their spring state). 181. Phyllotaxy, As already explained (48, 49), leaves are ar- ranged on the stem in two principal ways. They are either Alternate (Fig. 131, 143), that is, one after another, only a single leaf arising from each node or joint of the stem ; or Opposite (Fig. 147), when there is a pair of leaves on each joint of the stem ; one of the two leaves being in this case always situ- ated exactly on the opposite side of the stem from the other. A third, but uncommon arrangement, may be added ; namely, the Whorled, or verticillate (Fig. 148), when there are three or more leaves in a circle (whorl or verticil) on one joint of stem. But this is only a variation of the opposite mode; or rather the latter ar- rangement is the same as the whorled, with the number of the leaves reduced to two in each whorl. 182. Only one leaf is ever produced from the same point. When two are borne on the same joint, they are always on opposite sides of the stem, that is, are separated by half the circumference ; when in whorls of three, four, five, or any other number, they are equally distributed around the joint of stem, at a distance of one third, one fourth, or one fifth of the circumfer- ence from each other, according to their number. So they always have the greatest possible divergence from each other. Two or more leaves be- longing to the same joint of stem never stand side by side, or one above the other, in a cluster. 183. What are called clustered or fascicled leaves, and which FIG. 139. Clustered or fascicled leaves of the Larch. 72 ARRANGEMENT OF LEAVES ON THE STEM [LESSON 10. appear to be so, are always the leaves of a whole branch which remains so very short that they are all crowded together in a bundle or rosette ; as in the spring leaves of the Barberry and of the Larch (Fig. 139). In these cases an examination shows them to be nothing else than alternate leaves, very much crowded on a short spur ; and some of these spurs are seen in the course of the season to lengthen into ordinary shoots with scattered alternate leaves. So, likewise, each cluster of two or three needle-shaped leaves in Pitch Pines (as in Fig. 140), or of five leaves in White Pine, answers to a similar, extremely short branch, springing from the axil of a thin and slender scale, which represents a leaf of the main shoot. For Pines produce two kinds of leaves; — 1. primary, the proper leaves of the shoots, not as foliage, but in the shape of delicate scales in spring, which soon fall away ; and 2. secondary, the fascicled leaves, from buds in the axils of the former, and these form the actual foliage. 184. Spiral Arrangement of Leaves, If we examine any alternate-leaved stem, we shall find that the leaves are placed upon it in symmetrical order, and in a way per- fectly uniform for each species, but different in different plants. If we draw a line from the insertion (i. e. the point of attachment) of one leaf to that of the next, and so on, this line will wind spirally around the stem as it rises, and in the same species will always have just the same number of leaves upon it for each turn round the stem. That is, any two successive leaves will always be separated from each other by just an equal portion of the circumference of the stem. The distance in height between any two leaves may vary greatly, even on the same shoot, for that depends upon the length of the internodes or spaces between each leaf; but the distance as measured around the circumference (in other words, the angular divergence, or angle formed by any two successive leaves) is uniformly the same. is.">. The greatest possible divergence is, of course, where the second leaf stands on exactly the opposite side of the stem from the first, the third on the side opposite the second, and therefore over the FIG. 140. Piere of a branchlet of Pitch Pine, with three leaves in a fascicle or bundle, in the axil of a thin pcalo which answers to a primary leaf. The bundle is surrounded at the base by a sljort sheath, formed of the delicate scales of the axillary bud. LESSON 10.] IN A SPIRAL ORDER. 73 first, and the fourth over the second. This brings all the leaves into two ranks, one on one side of the stem and one on the other ; and is therefore called the two-ranked arrangement. It occurs in all Grasses, — in Indian Corn, for instance ; also in the Spiderwort, the Bell wort (Fig. 131) and Iris (Fig. 132), in the Bass wood or Lime- tree^. &c. This is the simplest of all arrangements. 186. Next to this is the three-ranked arrangement, such as we seeln Sedges, and in the Veratrum or White Hellebore. The plan of it is shown on a Sedge in Fig. 141, and in a diagram or cross- section underneath, in Fig. 142. Here the second leaf is placed one third of the way round the stem, the third leaf two thirds of the way round, the fourth leaf accordingly directly over the first, the fifth over the second, and so on. That is, three leaves occur in each turn round the stem, and they are separated from each other by one third of the circumference. 187; The next and one of the most com- mon is the five-ranked arrangement; which is seen in the Apple (Fig. 143), Cherry, Poplar, and the greater part of our trees and shrubs. In this case the line traced from leaf to leaf will pass twice round the stem before it reaches a leaf situated di- rectly over any below (Fig. 144). Here the sixth leaf is over the first ; the leaves stand in five perpendicular ranks, equally distant from each other ; and the distance between any two successive leaves is just two fifths of the circumference of the stem. The five-ranked arrangement Is expressed by the fraction f . fraction denotes the divergence of the successive leaves, i. e. the angle they form with each other : the numerator also expresses the number of turns made round the stem by the spiral line in complet- ing one cycle or set of leaves, namely 2 ; and the denominator gives the number of leaves in each cycle, or the number of perpendicular FIG. 141.

In the same way the fraction J stands for the two-ranked mode, and £ for the three-ranked : and so these different 143 sorts are expressed by the series of fractions J, •£, |. And the other cases known follow in the same numerical progression. 189. The next is the eight-ranked arrange- ment, where the ninth leaf stands over the first, and three turns are made around the stem to reach it ; so it is expressed by the fraction -g. This is seen in the Holly, and in the common Plantain. Then comes the tldrteen-ranked ar- rangement, in which the fourteenth leaf is over the first, after five turns around the stem. Of this we have a good example in the common Ilouseleek (Fig. 146). (190. The series so far, then, is £, £, f , f , T5-j ; the numerator and the denomi- nator of each fraction being those of the two next pre- ceding ones added together. At this rate the next higher should be /T, then £f , and so on ; and in fact just such cases are met with, and (commonly) no others. These higher sorts are found in the Pine Fam- ily, both in the leaves and the cones (Fig. 324), and in many other plants with small and crowd- ed leaves. But the number of the ranks, or of leaves in each cycle, can here rarely be made out by direct inspection: they may be ascer- tained, however, by certain simple mathematical computations, which are rather too technical for these Lessons.

A young plant of tho Hoiiseleok, with the leaves (not yet expanded) numbered, and exhibiting tho P ranked arrangement* LESSON 10.] ARRANGEMENT OF LEAVES IN THE BUD. 75 191. The arrangement of opposite leaves (181) is usually very simple. The second pair is placed over the intervals of the first ; the third over the intervals of the second, and so on (Fig. 147) ; the successive pairs thus crossing each other, — commonly at right angles, so as to make four upright rows. And whorled leaves (Fig. 148) follow a similar plan. 192* So the place of every leaf on every plant is fixed beforehand by unerring mathematical rule. As the stem grows on, leaf after leaf ap- pears exactly in its predes- tined place, producing a per- fect symmetry ; — a symme- try which manifests itself not in one single monotonous pattern for all plants, but in a definite number of forms exhibited by different spe- cies, and arithmetically ex- pressed by the series of frac- tions, J, -£, f , f- , -fy, ^8T, &c., according as the formative energy in its spiral course up the developing stem lays down at corresponding intervals 2, 3, 5, 8, 13, or 21 ranks of alternate leaves. 103. Vernation, sometimes called Prcefoliation, relates to the way in which leaves are disposed in the bud (180). It comprises two things ; — 1st, the way in which each separate leaf is folded, coiled, or packed up in the bud ; and 2d, the arrangement of the leaves in the bud with respect to one another. The latter of course depends very much upon the phyllotaxy, i. e. the position and order of the leaves upon the stem. The same terms are used for it as for the arrange- ment of the leaves of the flower in the flower-bud : so we may pass them by until we come to treat of the flower in this respect. 194;. As to each leaf separately, it is sometimes straight and open in vernation, but more commonly it is either bent, folded, or rolled up. When the upper part is bent down upon the lower, as the young blade in the Tulip-tree is bent upon the leafstalk, it is said to be inflexed or reclined in vernation. When folded FIG. 147. Opposite leaves of the Spindle-tree or Burning-bush. FIG, 148. Whorled or verticillate leaves of Galium or Bedstraw. 76 ARRANGEMENT OF FLOWERS ON THE STEM. [LESSON 11. by the midrib so that the two halves are placed face to face, it is conduplicate (Fig. 149), as in the Magnolia, the Cherry, and the Oak : when folded back and forth like the plaits of a fan, it is plicate or plaited (Fig. 150), as in the Maple and Currant. If rolled, it may be so either from the tip downwards, as in Ferns and the Sundew (Fig. 154), when in unrolling it resembles the head of a crosier, and is said to be circihate ; or it may be rolled up parallel with the axis, either from one edge into a coil, when it is convolute (Fig. 151), as in the Apricot and Plum, or rolled from both edges towards the midrib; — sometimes inwards, when it is involute (Fig. 152), as in the Violet and Water-Lily ; sometimes outwards, when it is revolute (Fig. 153), in the Rosemary and Azalea. The figures are diagrams, representing sections through the leaf, in the way they were represented by Linna3us. LESSON XL THE ARRANGEMENT OF FLOWERS ON THE STEM, OR INFLO. RESCENCE. ] 05. THUS far we have been considering the vegetation of the plant, and studying those parts, viz. root, stem, and leaves, by which it increases in size and extent, and serves the purpose of its indi- vidual life. But after a time each plant produces a different set of organs, — viz. flowers, fruit, and seed, — subservient to a different purpose, that is, the increase in numbers, or the continuance of the LESSON 11.] INDETERMINATE INFLORESCENCE. 77 species. The plant reproduces itself in new individuals by seed. Therefore the seed, and the fruit in which the seed is formed, and the flower, from which the fruit results, are named the Organs of Reproduction or Fructification. These we may examine in succes- sion. We begin, of course, with the flower. And the first thing to consider is the 196. Inflorescence, or the mode of flowering, that is, the situation and arrangement of blossoms on the plant. Various as this arrange- ment may seem to be, all is governed by a simple law, which is easily understood. As the position of every leaf is fixed beforehand by a mathematical law which prescribes where it shall stand (192), so is that of every blossom ; — and by the same law in both cases. For flowers are buds, developed in a particular way ; and flower- buds occupy the position of leaf-buds, and no other As leaf-buds are either terminal (at the summit of a stem or branch, 42), or axillary (in the axil of a leaf, 43), so likewise 197. Flowers are either terminal or axillary. In blossoming as in vegetation we have only buds terminating (5. e. on the summit of) stems or branches, and buds from the axils of leaves. But while the same plant commonly produces both kinds of leaf-buds, it rarely bears flowers in both situations. These are usually either all axil- lary or all terminal; — giving rise to two classes of inflorescence, viz. the determinate and the indeterminate. (15&. Indeterminate Inflorescence is that where the flowers all arise from axillary buds; as in Fig. 155, 156, 157, &c. ; and the reason why it is called indetermi- nate (or indefinite) is, that while the axillary buds give rise to flowers, the terminal bud goes on to grow, and continues the stem indefinitely. 199. Where the flowers arise, as in Fig. 155, singly from the axils of the ordinary leaves of the plant, they do not form flower- clusters, but are axillary and solitary. But when several or many flowers are produced near each other, the accompanying leaves are usually of smaller size, and often of a different shape or character: then they are called bracts ; and the flowers thus brought together FIG. 155 Moneywort (Lysimachia nummularia) of tho gardens, with axillary flower* 7* 78 ARRANGEMENT OF FLOWERS ON THE STEM. [LESSON 11. form one cluster or inflorescence. The sorts of inflorescence of the indeterminate class which have received separate names are chiefly the following : viz. the Raceme, the Corymb, the Umbel, the Spike, the Head, the Spadix, the Catkin, and the Panicle. 200. Before illustrating these, one or two terms, of common oc- currence, may be defined. A flower (or other body) which has no stalk to support it, but which sits directly on the stem or axis it pro- ceeds from, is said to be sessile. If it has a stalk, this is called its peduncle. If the whole flower-cluster is raised on a stalk, this is called the peduncle, or the common peduncle (Fig. 156, p) ; and the stalk of each particular flower, if it have any, is called the pedicel or partial peduncle (p1). The portion of the general stalk along which flowers are dis- posed is called the axis of inflorescence, or, when cov- ered with sessile flowers, the rhachis (back-bone), and sometimes the receptacle. The leaves of a flower- cluster generally are termed bracts. But when we wish particularly to distinguish them, those on the peduncle, or main axis, and which have a flower in their axil, take the name of bracts (Fig. 156, b) ; and those on the pedicels or partial flower-stalks, if any, that ofbractlets (Fig. 156, b'). 201. A Raceme (Fig. 156, 157) is that form of flower- cluster in which the flowers, each on their ovni foot- stalk or pedicel, are arranged along a common stalk or axis of inflorescence ; as in the Lily of the Valley, Currant, Choke-Cherry, Barberry, &c. Each flower comes from the axil of a small leaf, or bract, which, however, is often so small that it might escape notice, and which sometimes (as in the Mustard Family) disappears alto- gether. The lowest blossoms of a raceme are of course the oldest, and therefore open first, and the order of blossoming is ascending, from the bottom to the top. The summit, never being stopped by a terminal flower, may go on to grow, and often does so (as in the common Shepherd's Purse), producing lateral flowers one after an- other the whole summer long. 202. All the various kinds of flower-clusters pass one into another FIG. 156. A Raceme, with a general peduncle (p), pedicels (p'), brarts (/'), and bract- lets (ft'). LESSON 11.] RACEME, CORYMB, UMBEL, ETC. 79 by intermediate gradations of every sort. For instance, if we lengthen the lower pedicels of a raceme, and keep the main axis rather short, it is converted into 203. A Corymb (Fig. 158). This is the same as a raceme, except that it is flat and broad, either convex, or level-topped, as in the Hawthorn, owing to the lengthening of the lower pedicels while the uppermost remain shorter. 204. The main axis of a corymb is short, at least in comparison with the lower pedicels. Only suppose it to be so much contracted that the bracts are all brought into a cluster or circle, and the corymb becomes 205. An Umbel (Fig. 159), — as in the Milkweed and Primrose, — a sort of flower-cluster where the pedicels all spring apparently from the same point, from the top of the peduncle, so as to resemble, when spreading, the rays of an umbrella, whence the name. Here the pedicels are sometimes called the rays of the umbel. And the bracts, when brought in this way into a cluster or circle, form what is called an involucre. 206. For the same reason that the order of blossoming in a ra- ceme is ascending (201), in the corymb and umbel it is centripetal, that is, it proceeds from the margin or circumference regularly to- wards the centre ; the lower flowers of the former answering to the outer ones of the latter. Indeterminate inflorescence, therefore, is said to be centripetal in evolution. And by having this order of ining, all the sorts may be distinguished from those of the er, or the determinate class. In all the foregoing cases the flowers are raised on pedicels. These, however, are very short in many instances, or are wanting altogether; when the flowers are sessile (200). They are so in blosso other, FIG. 157. A raceme. 158. A corymJ), 159. An umbel. 80 ARRANGEMENT OF FLOWERS ON THE STEM. [LESSON 11. 207. The Spike. This is a flower-cluster with a more or less lengthened axis, along which the flowers are sessile or nearly so; as in the Mullein and the Plantain (Fig. ICO), It is just the same as a raceme, therefore, without any pedicels to the flowers. 208. The Head is a round or roundish cluster of flowers which are sessile on a very short axis or receptacle, as in the Button-ball, Button-bush (Fig. 1G1), and Red Clover. It is just what a spike would become if its axis were shortened ; or an umbel, if its pedicels were all shortened until the flowers became sessile or apparently so. The head of the Button-bush (Fig. 161) is naked ; but that of the Thistle, of the Dandelion, the Cichory (Fig. 221), and the like, is surrounded by empty bracts, which form an involucre. Two particular forms of the spike and the head have received particular names, namely, the Spadix 160 and the Catkin. 209. A Spadix is nothing but a fleshy spike or head, with small and often imperfect flowers, as in the Calla, the Indian Turnip (Fig. 162), Swrot Flair, &c. It is commonly covered by a peculiar enveloping leaf, called a spathe. FIG. lf)0. Ppike of the common Plantain or Ribwort. FIG. 161. Iload of the Button-hush (Cephalanthus). FIG. 1G2. Spadix and spathe of the Indian Turnip ; the latter cut through belovr. LESSON 11.] DETERMINATE INFLORESCENCE. 81 210. A Catkin or Ament is the name given to the scaly sort of spike of the Birch and Alder, the Willow and Poplar, and one sort of flower-clusters of the Oak, Hickory, and the like ; — on which ac- count these are called Amentaceous trees. 211. Sometimes these forms of flower-clusters become compound. For example, the stalks which, in the simple umbel such as has been described (Fig. 159), are the pedicels of single flowers, may themselves branch in the same way at the top, and so each become the support of a smaller umbel ; as is the case in the Parsnip, Cara- way, and almost the whole of the great family of what are called Umbelliferous (i. e. umbel-bearing) plants. Here the whole is termed a compound umbel; and the smaller or partial umbels take the name in English of umbellets. The general involucre, at the base of the main umbel, keeps that name ; while that at the base of each umbellet is termed a partial involucre or an involucel. 212. So a corymb (Fig. 158) with its separate stalks branching again, and bearing smaller clusters of the same sort, is a compound corymb ; of which the Moun- tain Ash is a good example. A raceme where what would be the pedicels of single flowers . I ($ become stalks, along which flowers are disposed \ Y' on their own pedicels, forms a compound raceme, (TV\ £) a* in the Goat's-beard and the False Spikenard. But when what would have been a raceme or a. corymb branches irregularly into an open and more or less compound flower-cluster, we have what is called 213. A Panicle (Fig. 163); as in the Oat and in most common Grasses. Such a raceme as that of the diagram, Fig. 156, would be changed into a panicle like Fig. 163, by the production of a flower from the axil of each of the bractlets fr. 214. A Thyrsus is a compact panicle of a pyramr- idal or oblong shape ; such as a bunch of grapes, or the cluster of the Lilac or Horsechestnut. 215. Determinate Inflorescence is that in which the flowers are from terminal buds. The simplest case is where a stem bears a soli- tary, terminal flower, as in Fig. 163*. This stops the growth of FIG. 1C3. A Panicle 82 ARRANGEMENT OF FLOWERS ON THE STEM. [LESSON 11. the stem ; for its terminal bud, being changed into a blossom, can no more lengthen in the manner of a leaf-bud. Any further growth b a b c b c a e b must be from axillary buds developing into branches. If such branches are leafy shoots, at length terminated by single blossoms, the inflorescence still consists of solitary flowers at the summit of the stem and branches. But if the flowering branches bear only bracts in place of ordinary leaves, the result is the kind of flower-cluster called ^v 216. A Cymet This is commonly a flat-topped or con- \jj 3 a.

It is the con- tinued repetition of this which forms the full or compound cyme, such as that of the Laurustinus, Hobblebush, Dogwood, and Hy- drangea (Fig. 167). 218. A Fascicle, like that of the Sweet- William and Lychnis of the gardens, is only a cyme with the flowers much crowded, as it were, into a bundle. 219. A Gloinemle is a cyme still more compacted, so as to form a sort of head. It may be known from a true head by the flowers not expanding centripetally, that is, not from the circumference to- wards the centre, or from the bottom to the top. 220. The illustrations of determinate or cymose inflorescence have been taken from plants with opposite leaves, which give rise to the most regular cymes. But the Rose, Cinquefoil, Buttercup, and the like, with alternate leaves, furnish equally good examples of this class of flower-clusters. 221.

Even the two classes of inflorescence are often found com- bined in the same plant. For instance, in the whole Mint Family, 84 THE FLOWER. [LESSON 12.' the flower-clusters are centrifugal, that is, are cymes or fascicles ; but they are themselves commonly disposed in spikes or racemes, which are centripetal, or develop in succession from below up- wards. LESSON XII. THE FLOWER: ITS PARTS OR ORGANS. 223. HAVING considered, in the last Lesson, the arrangement of flowers on the stem, or the places from which they arise, we now direct our attention to the flower itself. (224. Nature and Use Of the Flower, The object of the flower is the production of seed. The flower consists of all those parts, or organs, which are subservient to this end. Some of these parts are neces- sary to the production of seed. Others serve merely to protect or support the more essential parts. FIG. 1G7. Cyme of the Wild Hydrangea (with neutral flowers in the border). LESSON 12.] ITS PARTS OR ORGANS* 85 225. The Organs Of the Flower are therefore of two kinds ; namely, first, the protecting organs, or leaves of the flower, — also called the floral envelopes, — and, second, the essential organs. The latter are situated within or a little above the former, and are enclosed by them in the bud. „ 220. TllC Floral Envelopes in a complete flower are double ; that is, they consist of two whorls (181), or circles of leaves, one above or within the other. The outer set forms the Calyx ; this more com- monly consists of green or greenish leaves, but not always. The inner set, usually of a delicate texture, and of some other color than green, and in most cases forming the most showy part of the blos- som, is the Corolla. 227. The floral envelopes, taken together, are sometimes called the Perianth. This name is not much used, however, except in cases where they form only one set, at least in appearance, as in the Lily, or where, for some other reason, the limits between the calyx and the corolla are not easily made out. 228. Each leaf or separate piece of the corolla is called a Petal ; each leaf of the calyx is called a Sepal. The sepals and the petals • — or, in other words, the leaves of the blossom — serve to protect, support, or nourish the parts within. They do not themselves make a perfect flower. 229. Some plants, however, naturally produce, besides their per- fect flowers, others which consist only of calyx and corolla (one or both), that is, of leaves. These, destitute as they are of the essential organs, and incapable of producing seed, are called neutral flowers. We have an example in the flowers round the margin of the cyme of the Hydrangea (Fig. 167), and of the Cranberry-Tree, or Snowball, in their wild state. By long cultivation in gardens the whole cluster has been changed into showy, but useless, neutral flowers, in these and some other cases. What are called double flowers, such as full Roses (Fig. 173), Buttercups, and Camellias, are blossoms which, under the gardener's care, have developed with all their essential organs changed into petals. But such flowers are always in an unnatural or monstrous condition, and are incapable of maturing seed, for want of 230. The Essential Organs. These are likewise of two kinds, placed one above or within the other ; namely, first, the Stamens or fertil- izing organs, and, second, the Pistils, which are to be fertilized and bear the seeds. 8 86 THE FLOWER. [LESSON 12. 231. Taking them in succession, therefore, beginning from below, or at the outside, we have (Fig. 168, 169), first, the calyx or outer circle of leaves, which are individually termed sepals (a) ; secondly, the corolla or inner circle of delicate leaves, called petals (b) ; then a set of stamens (c) ; and in the centre one or more pistils (d). The end of the flower-stalk, or the short 168 axis, upon which all these parts stand, is called the Torus or Receptacle. 232. We use here for illus- tration the flower of a spe- cies of Stonecrop (Sedum ter- natum), — which is a com- mon plant wild in the Middle States, and in gardens almost everywhere, — because, al- though small, it exhibits all the parts in a perfectly simple and separate state, and so answers for a sort of pattern flower, better than any larger one that is common c and well known. 233. A Stamen consists of two parts, namely, the Filament or stalk (Fig. 170, «), and the Anther (b). The latter is 0 the only essential part. It is a case, commonly with two lobes or cells, each opening lengthwise by a slit, at the proper time, and discharging a pow- der or dust-like substance, usually of a yellow color. This powder is the Pollen, or fertilizing matter, to produce which is the sole office of the stamen. "2'\\. A Pistil is distinguished into three parts ; namely, — beginning from below, — the Ovary, the Style, and the Stigma. The Ovary is the hollow case or young pod (Fig. 171, a), containing rudimentary seeds, called Ovules (d). Fig. 172, representing a pistil like that of FIG. 1C8.

LESSON 12.] ITS PARTS OR ORGANS. 87 Fig. 169, d, but on a larger scale, and with the ovary cut across, shows the ovules as they appear in a transverse section. The style (Fig. 171, b) is the tapering part above, sometimes long and slender, sometimes short, and not rarely altogether wanting, for it is not an essential part, like the two others. The stigma (c) is the tip or some other portion of the style (or of the top of the ovary when there is no distinct style), consisting of loose tissue, not cov- ered, like the rest of the plant, by a skin or epi- dermis. It is upon the stigma that the pollen falls ; and the result is, that the ovules contained in the ovary are fertilized and become seeds, by having an embryo (16) formed in them. To the pistil, therefore, all the other organs of the blos- som are in some way or other subservient : the stamens furnish pollen to fertilize its ovules ; the corolla and the calyx form coverings which pro- tect the whole. 234\ These are all the parts which belong to any flower. But these parts appear under a variety of forms and combinations, some of them greatly disguising their natural appearance. To understand the flower, therefore, under whatever guise it may assume, we must study its plan. 68 PLAN OF THE FLOWER. [LESSON 13. LESSON XIII. THE PLAN OF THE FLOWER. 235. THE FLOWER, like every other part of the plant, is formed upon a plan, which is essentially the same in all blossoms ; and the student should early get a clear idea of the plan of the flower. Then the almost endless varieties which different blossoms present will be at once understood whenever they occur, and will be regarded with a higher interest than their most beautiful forms and richest colors are able to inspire. 236. We have already become familiar with the plan of the vege- tation;— with the stem, consisting of joint raised upon joint, each bearing a leaf or a pair of leaves ; with the leaves arranged in sym- metrical order, every leaf governed by a simple arithmetical law, which fixes beforehand the precise place it is to occupy on the stem ; and we have lately learned (in Lesson 11) how the position of each blossom is determined beforehand by that of the leaves ; so that the shape of every flower-cluster in a bouquet is given by the same sim- ple mathematical law which arranges the foliage. Let us now con- template the flower in a similar way. Having just learned what parts it consists of, let us consider the plan upon which it is made, and endeavor to trace this plan through some of the various forms which blossoms exhibit to our view. 237. In order to give at the outset a correct idea of the blossom, we took, in the last Lesson, for the purpose of explaining its parts, a perfect, complete, regular, and symmetrical flower, and one nearly as simple as such a flower could well be. Such a blossom the botanist regards as :>:!*. A Typical Flower, that is, a pattern flower, because it well ex- emplifies the plan upon which all flowers are made, and serves as what is called a type, or standard of comparison. 239. Another equally good typical flower (except in a single re- spect, which will hereafter be mentioned), and one readily to be ob- tained in the summer, is that of the Flax (Fig. 174). The parts differ in shape from those of the Stonecrop ; but the whole plan is evidently just the same in both. Only, while the Stonecrop has ten stamens, or in many flowers eight stamens, — in all cases just twice LESSON 13.] PERFECT AND IMPERFECT FLOWERS. 89 as many as there are petals, — the Flax has only five stamens, or just as many as the petals. Such flowers as these are said to be Perfect, because they are provided with both kinds of essential organs (230), namely, stamens and pistils ; Complete, because they have all the sorts of organs which any flower has, namely, both calyx and corolla, as well as stamens and pistils ; Regular, because all the parts of each set are alike in shape and size ; and Symmetrical, because they have an equal number of parts of each sort, or in each set or circle of organs. That is, there are five sepals, five petals, five stamens, or in the Stonecrop ten stamens (namely, two sets of five each), and live pistils. 240. On the other hand, many flowers do not present this perfect symmetry and reg- ularity, or this completeness of parts, ingly, we may have 241. Imperfect, or Separated Flowers; which are those where the stamens and pistils are in separate blossoms ; that is, one sort of flowers has stamens and no pistils, and another has pistils and no sta- mens, or only imperfect ones. The blossom which has stamens but no pistils is called a staminate or sterile flower (Fig. 176) ; and the corresponding one with pistils but no stamens is called a pistil- late or fertile flower (Fig. 177). The two sorts may grow on distinct plants, from different roots, as they do in the Willow and Poplar, the Hemp, and the Moonseed FIG. 174. Flowers of the common Flax : a perfect, complete, regular, and symmetrical blossom, all its parts in fives. 175. Half of a Flax-flower divided lengthwise, and enlarged. FIG. 178.

(Fig. 176, 177) ; when the flowers are said to be dioecious (from two Greek words meaning in two households). Or the two may occur on the same plant or the same stem, as in the Oak, Walnut, Nettle, and the Castor-oil Plant (Fig. 178); when the flowers are said to be mo- noecious (that is, in one household). A flower may, however, be perfect, that is, have both stamens and pistils, and yet be incomplete. 242. Incomplete Flowers are those in which one or both sorts of the floral envelopes, or leaves of the blossom, are wanting. Some- times only one sort is wanting, as in the Castor-oil Plant (Fig. 178) and in the Anem- one (Fig. 179). In this case the missing sort is always supposed to be the inner, that is, the corolla ; and accordingly such flowers are said to be apetalous (meaning without petals). Occasionally both the corolla and the calyx are wanting, when the flower has no proper cover- ings or floral envelopes at all. It is then said to be naked, as in the Lizard's- tail (Fig. 180), and in the Willow. 243. Our two pattern flowers (Fig. 168, 174) are regular and symmetrical (239). We commonly expect this to be the case in living things. The corresponding parts of plants, like the limbs or members of ani- mals, are generally alike, and th<; whole arrange- ment is symmetrical. This symmetry pervades the blossom, especially. But the student may often fail to perceive FIG. 178.

LESSON 13.J IRREGULAR AND UNSYMMETRICAL FLOWERS 91 it, at first view, at least in cases where the plan is more or less obscured by the leaving out (obliteration) of one or more of the members of the same set, or by some in- equality in their size and shape. The latter circumstance gives rise to 244. Irregular Flowers, This name is given to blossoms in which the different members of the same sort, as, for exam- ple, the petals or the stamens, are unlike in size or in form. We have familiar cases of the sort in the Larkspur (Fig. 183, 184), and Monkshood (Fig. 185, 186); also in the Vio- let (Fig. 181, 182). In the latter it is the corolla principally which is ir- regular, one of the petals being larger than the rest, and extended at the base into a hollow protuberance or spur. In the Larkspur (Fig. 183), both the calyx and the corolla par- take of the irregularity. This and the Monkshood are likewise good ex- amples of 245. Unsymmetrfcal Flowers, We call them unsymmetrical, when the different sets of organs do not agree in the number of their parts. The irregular calyx of Larkspur (Fig. 183, 184) consists of five sepals, one of which, larger than the rest, is prolonged behind into a large spur; but the corolla is made of only four petals (of two shapes); FIG. 181. Flower of a Violet. 182. Its calyx and corolla displayed: the five smaller parts are the sepals ; the five intervening larger ones are the petals. FIG. 183. Flower of a Larkspur. 184.

And the Monkshood (Fig. 185, 18G) has five very dissimilar sepals, and a corolla of only two, very small, curiously-shaped petals ; the three need- ed to make up the symmetry being left out. For a flower which is unsymmet- rical but regular, we may take the com- mon Purslane, which has a calyx of only two sepals, but a corolla of five petals, from seven to twelve stamens, and about six styles. The Mustard, and all flowers of that family, are un- symmetrical as to the stamens, these being six in number (Fig. 188, while the leaves of the blossom (sepals and petals) are each only four (Fig. 187). Here the stamens are irregular also, two of them being shorter than the other four. 246. Numerical Plan of the Flower, Although not easy to make out in all cases, yet generally it is plain to see that each blossom is based upon a particular number, which runs through all or most of its parts. And a prin- cipal thing which a botanist notices when examin- ing a flower is its numerical plan. It is upon this that the symmetry of the blossom depends. Our two pattern flowers, the Stonecrop (Fig. 1C8) and the Flax (Fig. 174), are based upon the number five, •which is exhibited in all their parts. Some flowers of this same Stonecrop have their parts in fours, and then that number runs throughout ; namely, there are four sepals, four petals, eight stamens (two sets), and four pistils. The Mustard (Fig. 187, 188), Radish, FIG. 185. Flower of a Monkshood. ]Rfi. Its parts displayed : the five larper pieces are the nopals ; the two small ones under tlio hood are petals ; the stamens and pistils are in the centre. FIG. 187. Flower of Mustard. 188. Its stamens and pistil separate and enlarged. LESSON 13.] THE RELATIVE POSITION OF ITS PARTS. 93 &c., also have their flowers constructed on the plan of four as to the calyx and corolla, but this number is interfered with in the stamens, either by the leaving out of two sta- mens (which would complete two sets), or in some other way. Next to five, \ the most common number in flowers is three. On this number the flowers of Lily, Crocus, Iris, Spiderwort, and Trillium (Fig. 189) are constructed. In the Lily and Crocus the leaves of the flower at first view appear to be six in one set ; but the bud or just- 139 opening blossom plainly shows these to consist of an outer and an inner circle, each of three parts, namely, of calyx and corolla, both of the same bright color and delicate texture. In the Spiderwort and Trillium (Fig. 189) the three outer leaves, or sepals, are green, and dif- ferent in texture from the three inner, or the petals ; the stamens are six (namely, two sets of three each), and the pistils three, though partly grown together into one mass. 247. Alternation of Parts, The symmetry of the flower is likewise shown in the arrangement or relative position of successive parts. The rule is, that the parts of successive circles alternate with one another. That is, the petals stand over the intervals between the sepals ; the stamens, when of the same number, stand over the intervals between the petals ; or when twice as many, as in the Trillium, the outer set alternates with the petals, and the inner set, alternating with the other, of course stands before the petals ; and the pistils alter- nate with these. This is shown in Fig. 189, and in the diagram, or cross-section of the same in the bud, Fig. 190. And Fig. 191 is a similar diagram or ground-plan (in the form of a FIG. 189. Flower of Trillium erectum, or Birthroot, spread out a little, and viewed from above. FIG. 190.

[LESSON 13. eection made across the bud) of the Flax blossom, the example of a pattern symmetrical flower taken at the beginning of this Lesson, with its parts all in fives. 248. Knowing in this way just the position which each organ should occupy in the flower, it is readily understood that flowers often become unsymmetrical through the loss of some parts, which belong to the plan, but are obliterated or left out in the execution. For ex- ample, in the Larkspur (Fig. 183, 184), as there are five sepals, there should be five petals likewise. We find only four ; but the vacant place where the fifth belongs is plainly rec- ognized at the lower side of the flower. Also the similar plan of the Monkshood (Fig. 186) equally calls for five petals ; but three of them are entirely obliterated, and the two that remain are reduced to slender bodies, which look as unlike or- dinary petals as can well be imagined. Yet their position, answer- ing to the intervals between the upper sepals and the side ones, reveals their true nature. All this may perhaps be more plainly shown by corresponding diagrams of the calyx and corolla of the Larkspur and Monkshood (Fig. 192, 193), in which the places of the missing petals are indicated by faint dotted lines. The oblitera- tion of stamens is a still more common case. For example, the Snapdragon, Foxglove, Gerardia, and almost all flowers of the large Figwort family they belong to, have the parts of the calyx and corolla five each, but only four stamens (Fig. 194) ; the place on the upper side of the flower where the fifth stamen belongs is vacant. That there is in such cases a real obliteration of the miss- ing part is shown by the 2-1!). Abortive Organs, or vestiges which are sometimes met with; • — bodies which stand in the place of an organ, and represent it, although wholly incapable of fulfilling its office. Thus, in the Fig- wort family, the fifth stamen, which is altogether missing in Gerardia (Fig. 194) and most others, appears in the Figwort as a little scale, and in Pentstemon (Fig. 195) and Turtlehead as a sort of filament without any anther ; — a thing of no use whatever to the plant, but FIG. 192. Diagram of the calyx and corolla of a Larkspur. 193. Similar diagram of Monkshood. The dotted lines show where the petals are wanting ; one in the former, three in the latter. LESSON 13.1 ABORTIVE ORGANS. 95 very interesting to the botanist, since it completes the symmetry of the blossom. And to show that this really is the lost stamen, it now and then bears an anther, or the rudiment of one. So the flower of Catalpa should likewise have five stamens ; but we seldom find more than two good ones. Still we may generally discern the three others, as vestiges or half-obliterated stamens (Fig. 196). In separated flowers the rudiments of pistils are often found in the sterile blossom, and rudimentary sta- mens in the fertile blossom, as in Moon- seed (Fig. 177). 250. Multiplication of Parts, Quite in the opposite way, the simple plan of the flower is often more or less obscured by an increase in the number of parts. In the White Water-Lily, and in many Cactus-flowers (Fig. 197), all the parts are very numerous, so that it is hard to say upon what number the blos- som is constructed. But more com- monly some of the sets are few and definite in the number of their parts. The Buttercup, for instance, has five sepals and five petals, but many sta- mens and pistils ; so it is built upon the plan of five. The flowers of Mag- nolia have indefinitely numerous stamens and pistils, and rather numerous floral 195 envelopes ; but these latter are plainly distinguishable into sets o/ three ; namely, there are three sepals, and six petals in two circles, or nine in three circles, — showing that these blossoms are con- structed on the number three.

IN all the plant till we came to the blossom we found nothing but root, stem, and leaves (23, 118). However various or strange their shapes, and whatever their use, everything belongs to one of these three organs, and everything above ground (excepting the rare case of aerial roots) is either stem or leaf. We discern the stem equally in the stalk of an herb, the trunk and branches of a tree, the trailing or twining Vine, the straw of Wheat or other Grasses, the columnar trunk of Palms (Fig. 47), in the flattened joints of the Prickly-Pear Cactus, and the rounded body of the Melon Cactus (Fig. 76). Also in the slender runners of the Strawberry, the tendrils of the Grape-vine and Virginia Creeper, the creeping subterranean shoots of the Mint and Couchgrass, the tubers of the Potato and Artichoke, the solid bulb of the Crocus, and the solid part or base of scaly bulbs ; as is fully shown in Lesson 6. And in Lesson 7 and elsewhere we have learned to recognize the leaf alike in the thick seed-leaves of the Almond, Bean, Horsechestnut, and the like (Fig. 9-24), in the scales of buds (Fig. 77), and the thickened FIG. 197. A Cactus-flower, viz. of Mamillarla caespitosa of the Upucr Missouri LESSON 14.] ARRANGEMENT OF LEAVES IN THE BUD. 97 Scales of bulbs (Fig. 73-75), in the spines of the Barberry and the tendrils of the Pea, in the fleshy rosettes of the Houseleek, the strange fly-trap of Dionrca (Fig. 81), and the curious pitcher of Sar- racenia (Fig. 79). 252. Now the student who understands these varied forms or metamorphoses of the stem and leaf, and knows how to detect the real nature of any part of the plant under any of its disguises, may readily trace the leaf into the blossom also, and perceive that, as to their morphology, 253. Flowers are altered Branches, and their parts, therefore, altered leaves. That is, certain buds, which might have grown and length- ened into a leafy branch, do, under other circumstances and to ac- complish other purposes, develop into blossoms. In these the axis remains short, nearly as it is in the bud ; the leaves therefore remain close together in sets or circles ; the outer ones, those of the calyx, generally partake more or less of the character of foliage ; the next set are more delicate, and form the corolla, while the rest, the sta- mens and pistils, appear under forms very different from those of ordinary leaves, and are concerned in the production of seed. This is the way the scientific botanist views a flower ; and this view gives to Botany an interest which one who merely notices the shape and counts the parts of blossoms, without understanding their plan, has no conception of. 254. That flowers answer to branches may be shown first from their position. As explained in the Lesson on Inflorescence, flowers arise from the same places as branches, and from no othdr ; flower- buds, like leaf-buds, appear either on the summit of a &tem, that is, a terminal bud, or in the axil of a leaf, as antwxillary bud (196). And at an early stage it is often impossible to foretell whether the bud is to give rise to a blossom or to a branch. 255. That the sepals and petals are of the nature of leaves is evident from their appearance ; persons who are not botanists com- monly call them the leaves of the flower. The calyx is most gen- erally green in color, and foliaceous (leaf-like) in texture. And though the corolla is rarely green, yet neither are proper leaves always green. In our wild Painted-Cup, and in some scarlet Sages, common in gardens, the leaves just under the flowers are of the brightest red or scarlet, often much brighter-colored than the corolla itself. And sometimes (as in many Cactuses, and in Carolina All- spice) there is sueh a regular gradation from the last leaves of the 9 98 MORPHOLOGY OF THE FLOWER. [LESSON 14. plant (bracts or bractlets) into the leaves of the calyx, that it is im- possible to say where the one ends and the other begins. And if sepals are leaves, so also are petals ; for there is no clearly fixed limit between them. Not only m the Carolina Allspice and Cactus (Fig. 197), but in the Water-Lily (Fig. 198) and a variety of flowers with more than one row of petals, there is such a complete transition between calyx and corolla that no one can surely tell how many of the leaves belong to the one and how many to the other. 256. It is very true that the calyx or the corolla often takes the form of a cup or tube, instead of being in separate pieces, as in Fig. 194-196. It is then composed of two or more leaves grown together. This is no objection to the petals being leaves ; for the same thing takes place with the ordinary leaves of many plants, as, for instance, in the upper ones of Honeysuckles (Fig. 132). 257. That stamens are of the same general nature as petals, and therefore a modification of leaves, is shown by the gradual transitions that occur between the one and the other in many blossoms ; es- pecially in cultivated flowers, such as Roses and Camellias, when they begin to double, that is, to change their stamens into petals. Some wild and. natural flowers show the same interesting transitions. The Carolina Allspice and the White Water-Lily exhibit complete gradations not only between sepals and petals, but between petals and stamens. The sepals of the Water-Lily are green outside, but white and petal-like on the inside ; the petals, in many rows, grad- ually grow narrower towards the centre of the flower ; some of these are tipped with a trace of a yellow anther, but still are petals ; the next are more contracted and stamen-like, but with a flat petal-like filament ; and a further narrowing of this completes the genuine sta- men. A series of these stages is shown in Fig. 198. 258. Pistils and stamens now and then change into each other in some Willows ; pistils often turn into petals in cultivated flowers ; and in the Double Cherry they occasionally change directly into small green leaves. Sometimes a whole blossom changes into a cluster of green leaves, as in the " green roses " which are occa- sionally noticed in gardens, and sometimes it degenerates into a leafy branch. So the botanist regards pistils also as answering to leaves. And his idea of a pistil is, that it consists of a leaf with its margins curved inwards till they meet and unite to form a closed cavity, the ovary, while the tip is prolonged to form the style and bear the stigma ; as will be illustrated in the Lesson upon the Pistil. LESSON 15.] THE CALYX AND COROLLA. 99 259. Moreover, the arrangement of the parts of the flower answers to that of leaves, as illustrated in Lesson 10, — either to a succes- sion of whorls alternating with each other in the manner of whorled leaves, or in some regular form of spiral arrangement. LESSON XV. MORPHOLOGY OF THE CALYX AND COROLLA. 260. HAVING studied the flower as a whole, we proceed to con- sider more particularly its several parts, especially as to the principal differences they present in different plants. We naturally begin with the leaves of the blossom, namely, the calyx and corolla. And first as to 261. The Growing together Of Parts, It is this more than anything else which prevents one from taking the idea, at first sight, that the flower is a sort of very short branch clothed with altered leaves. For most blossoms we meet with have some of their organs grown together more or less. We have noticed it as to the corolla of Ge- rardia, Catalpa, &c. (Fig. 194-196), in Lesson 13. This growing PIG. 198. Succession of sepals, petals, gradations between petals and stamens, and tn» stamens, of the Nymph«a, or White Water-Lily. 100 THE CALYX AND COROLLA. [LESSON 15. together takes place in two ways : either parts of the same kind, or parts of different kinds, may be united. The first we may call simply the union, the second the consoli- dation) of parts. 2 62. Union OF Cohesion with one another of parts of the same sort. We very com- monly find that the calyx or the corolla is a cup or tube, instead of a set of leaves. Take, for example, the flower of the Stra- monium or Thorn- Apple, where both the calyx and the corolla are so (Fig. 199); likewise the common Morning-Glory, and the figures 201 to 203, where the leaves of the corolla are united into one piece, but those of the calyx are separate. Now there are numerous cases of real leaves growing together much in the same way, — those of the common Thorough- wort, and the upper pairs in Woodbines or Honeysuckles, for example (Fig. 132) ; so that we might expect it to occur in the leaves of the blossom also. And that this is the right view to take of it plainly appears from the transitions everywhere met with in different plants, between a calyx or a corolla of separate pieces and one forming a perfect tube or cup. Figures 200 to 203 show one complete set of such gradations in the corolla, and Fig. 204 to 206 another, in short and open corollas. How many leaves or petals each corolla is formed of may be seen by the number of points or tips, or of the notches (called sinuses) which answer to the inter- vals between them. 203. When the parts are united in this way, whether much or little, the corolla is said to be monopetalous, and the calyx mono- sepalous. These terms mean " of one petal," or " of one sepal " ; that is, of one piece. Wherefore, taking the corolla or the calyx as a whole, we say that it is parted when the parts are separate almost to the base, as in Fig. 204 ; cleft or lobcd when the notches do not extend below the middle or thereabouts, as in Fig. 205 ; FIG. 190. Flower of the common Stramonium ; both the calyx and the corolla with then parts united into a tub*. LESSON 15.] UNION OF PARTS. 101 toothed or dentate, when only the tips are separate as short points ; entire, when the border is even, without points or notches, as in the common Morning- Glory, and very nearly so in Fig. 203 ; and so on ; — the terms being just the same as those applied to leaves and all other flat bodies, and illustrated in Lessons 8 and 9. 264. There is a set of terms applied particularly to calyxes, corollas, or other such bodies of one piece, to express their general shape, which we see is very various. The following are some of the principal : — Wheel-shaped, or rotate ; when spreading out at once, without a tube or with a very short one, something in the shape of a wheel or of its diverging spokes, as in the corolla of the Potato and Bitter- sweet (Fig. 204, 205). Salver-shaped, or salver-form ; when a flat-spreading border ifl raised on a narrow tube, from which it diverges at right angles, like the salver represented in old pictures, with a slender handle beneath. The corolla of the Phlox (Fig. 208) and of the Cypress- Vine (Fig. 202) are of this sort. FIG. 200. Corolla of Soapvvort (the same in Pinks, &c.), of 5 separate, long-clawed petals. F[G. 201. Flower of Gilia or Ipomopsis coronopifolia ; the parts answering to the dawn of the petals of the last figure here all united into a tube. FIG. 202.

Flower of the small Scarlet Morning-Glory, the five petals it is composed of perfectly united into a trumpet-shaped tube, with the spreading border nearly even (or entire). FIG. 204. Wheel-shaped and five-parted corolla of Bittersweet (Solanum Dulcamara). FIG, 205. Wheel-shaped and five-cleft corolla of the common Potato. FIG. 206. Almost entire and very open bell-shaped corolla of a Ground Cherry (Physalis). 9* 102 THE CALYX AND COROLLA. [LESSON 15. Bell-shaped, or campanulate ; where a short and broad tube widens upward, in the shape of a bell, as in Fig. 207. Funnel-shaped, or funnel-form ; gradually spreading at the sum- mit of a tube which is narrow below, in the shape of a funnel or tunnel, as in the corolla of the common Morning-Glory, and of the Stramonium (Fig. 199). Tubular ; when prolonged into a tube, without much spreading at the border, as in .the corolla of the Trumpet Honeysuckle, the calyx of Stramonium (Fig. 199), &c. 210 211 265. In most of these cases we may distinguish two parts ; namely, the tube, or the portion all in one piece and with its sides upright or nearly so ; and the border or limb, the spreading portion or summit. The limb may be entire, as in Fig. 203, but it is more commonly lobed, that is, partly divided, as in Fig. 202, or parted down nearly to the top of the tube, as in Fig. 208, &c. 266. So, likewise, a separate petal is sometimes distinguishable into two parts ; namely, into a narrowed base or stalk-like part (a? in Fig. 200, where this part is peculiarly long), called the claw, and a spreading and enlarged summit, or body of the petal, called the lamina or blade. 267. When parts of the same set are not united (as in the Flax, Cherry, &c., Fig. 212-215), we call them distinct. Thus the sepals or the petals are distinct when not at all united with each other. As a calyx with sepals united into one body is called monosepalous (263, that is, one-sepalled), or sometimes monophyllous, that is, one-leaved ; so, on the other hand, when the sepals are distinct, it is said to be PIG. 207. Flower of the Harebell, with a rampannlate or hell-shaped corolla. 208. Of a Phlox, with salver-shaped corolla. 209. Of Dead-Nettie (Lamimn), with lahiatc ringent (or gaping) corolla. 210. Of Snapdragon, with labiate personate corolla. 211. Of Toad-Flax, with a similar corolla spurred at the base. LESSON 15.] CONSOLIDATION OF PARTS. 103 polysepalous, that is, composed of several or many sepals. And a corolla with distinct petals is said to be polypetalous. 268. Consolidation, the growing together of the parts of two or more different sets. In the most natural or pattern flower (as explained in Lessons 13 and 14), the several parts rise from the receptacle or axis in succes- sion, like leaves upon a very short stem ; the petals just above or within the sepals, the stamens just above or within these, and then the pistils next the summit or centre. Now when contiguous parts of different sorts, one within the other, unite at their base or origin, it obscures more or less the plan of the flower, by consolidating organs which in the pattern flower are entirely separate. 213 269. The nature of this con- solidation will be at once un- derstood on comparing the fol- lowing series of illustrations. Fig. 212 represents a flower of the common Flax, cut through lengthwise, so as to show the attachment (or what the bot- anist calls the insertion) of all the parts. Here they are all inserted on, that is grow out of, the receptacle or axis of the blossom. In other words, there is no union at all of the parts of contiguous circles. So the parts are said to be free. And the sepals, petals, and stamens, all springing of course from beneath the pistils, which are on the very summit of the axis, are said to be hypqqynom (a term composed of two Greek words, mean- ing "under the pistil"). •»• FIG. 212. A Flax-flower, cut through lengthwise. FIG. 213. Flower of a Cherry, divided in the same way. FIG. 214, Flower of the common Purslane, divided lengthwise. 104 THE CALYX AND COROLLA. [LESSON 15. 270. Fig. 213 is a flower of a Cherry, cut through lengthwise in the same way. Here the petals and the stamens grow out of, that is, are inserted on, the calyx ; in other words they cohere or are consolidated with the base of the calyx up to a certain height. In such cases they are said to be perigynous (from two Greek words, meaning around the pistil). The consolidation in the Cherry is con- fined to the calyx, corolla, and stamens : the calyx is still free from the pistil. One step more we have in 271. Fig. 214, which is a similar section of a flower of a Purslane. Here the lower part of the calyx (carrying with it of course the petals and stamens) is coherent with the surface of the whole lower half of the ovary. Therefore the calyx, seeming to rise from the mid- dle of the ovary, is said to be half superior, instead of being inferior, as it is when entirely free. It is better to say, however, calyx half-adherent to the ovary. Every gradation occurs between n such a case and that of a calyx altogether free or inferior, as we see in different Purslanes and Saxifrages. The consol- idation goes farther, 272. In the Apple, Quince, Hawthorn (Fig. 215), &c. Here the tube of the calyx is consolidated with the whole surface of the ovary ; and its limb, or free part, therefore appears to spring from its top, instead of underneath it, as it naturally should. So the calyx is said to be superior, or (more properly) adherent to, or coherent with, the ovary. In most cases (and very strikingly in the Evening Primrose), the tube of the calyx is continued on more or less beyond the ovary, and has the petals and stamens consolidated with it for some dis- tance; these last, therefore, being borne on the calyx, are said to be perigynous, as before (270). FIG. 215. Flower of a Hawthorn, divided lengthwise. FIG. 216. Flower of the Cranberry, divided lengthwise. LESSON 15.] IRREGULARITY OF PARTS. 105 273. But if the tube of the calyx ends immediately at the summit of the ovary, and its lobes as well as the corolla and stamens are as it were inserted directly on the ovary, they are said to be epigynous (meaning on the pistil), as in Cornel, the Huckleberry, and the Cran- berry (Fig. 216). 274. Irregularity Of Parts in the calyx and corolla has already been noticed (244) as sometimes obstructing one's view of the real plan of a flower. There is infinite variety in this respect ; but what has already been said will enable the student to understand these irreg- ularities when they occur. We have only room to mention one or two cases which have given rise to particular names. A very common kind, among polypetalous (267) flowers, is 275. The Papilionaceous flower of the Pea, Bean, and nearly all that family. In this we have an 21? irregular corolla of a peculiar shape, which Linnaeus likened to a butterfly (whence the term, papilio being the Latin name for a but- terfly) ; but the resemblance is not very obvious. The five pet- als of a papilionaceous corolla (Fig. 217) have received different names taken from widely different objects. The upper and larger petal (Fig. 218, 5), which is gen- erally wrapped round all the rest in the bud, is called the standard or banner. The two side petals (id) are called the ivings. And the two anterior ones (&), the blades of which commonly stick together a little, and which en- close the stamens and pistil in the flower, from their forming a body shaped somewhat like the keel, or rather the prow, of an ancient boat, are together named the keel. 276. The Labiate or bilabiate (that is, two-lipped) flower is a very common form of the monopetalous corolla, as in the Snapdragon FIG. 217. Front view of the papilionaceous corolla of the Locust-tree. 218. The parts of the same, displayed' 106 THE CALYX AND COROLLA. [LESSON 15. (Fig. 210), Toad-Flax (Fig. 211), Dead-Nettie (Fig. 209), Catnip, Horsemint, &c. ; and in the Sage, the Catalpa, &c., the calyx also is two-lipped. This is owing to unequal union of the different parts of the same sort, as well as to diversity of shape. In the corolla two of the petals grow together higher than the rest, sometimes to the very top, and form the upper lip, and the three remaining ones join on the other side of the flower to form the lower lip, which therefore is more or less three-lobed, while the upper lip is at most only two- lobed. And if the calyx is also two-lipped, as in the Sage, — since the parts of 'the calyx always alternate with those of the corolla (247), — then the upper lip has three lobes or teeth, namely, is com- posed of three sepals united, while the lower has only two ; which is the reverse of the arrangement in the corolla. So that all these flowers are really constructed on the plan of five, and not on that of two, as one would at first be apt to suppose. In Gerardia, &c. (Fig. 194, 195), the number five is evident in the calyx and corolla, but is more or less obscured in the stamens (249). In Catalpa this num- ber is masked in the calyx by irregular union, and in the stamens by abortion. A different kind of irregular flower is seen in 277. The Ligulate or strap- sltujH'd corolla of most com- pound flowers. "What was called the compound flower of a Dandelion, Succory (Fig. 221), Thistle, Sunflower, As- ter, Whiteweed, &c., consists of many distinct blossoms, closely crowded together into a head, and surrounded by an involucre (208). People who are not botanists commonly take the whole for one flower, the involucre for a calyx, and corollas of the outer or of all the flowers as petals. And this is a very natural mistake when the flowers around the edge have flat and open or strap-shaped corollas, while the rest are regular and tubular, but small, as in the Whiteweed, Sunflower, &c. Fig. 219 represents such a case in a Coreopsis, with the head, or so-called compound flower, cut through ; and in Fig. 220 we see one of the perfect flowers of the centre or di&k, with a reg- ular tubular corolla (a), and with the slender bract (b) from whose FIG. 219. Head of flowers (the so-called " compound flower ") of Coreopsis, divided lengthwise. LESSON 15.] SO-CALLED COMPOUND FLOWERS. 107 axil it grew-; and also one belonging to the margin, or ray, with a strap-shaped corolla (c), borne in the axil of a leaf or bract of 220 the involucre (d). Here the ray-flower consists merely of a strap- shaped corolla, raised on the small rudiment of an ovary; it is therefore a neutral flower, like those of the ray or margin of the cluster in Hydrangea (229, Fig. 167), only of a different shape. More commonly the flowers with a strap-shaped corolla are pis- tillate, that is, have a pistil only, and produce seed like the others, as in Whiteweed. But in the Dandelion, Succory (Fig. 221, 222), and all of that tribe, these flowers are perfect, that is, bear both stamens and pistils. And moreover all the flowers of the head are strap-shaped and alike. 278. Puzzling as these strap-shaped corollas appear at first view, an attentive inspection will generally reveal the plan upon which they are constructed. We can make out pretty plainly, that each one consists of five petals (the tips of which commonly appear as five teeth at the extremity), united by their contiguous edges, except on FIG. 220. A slice of Fig. 219, more enlarged, with one tubular perfect flower (a) left standing on the receptacle, with its bractlet or chaff (6), one ligulate, neutral ray-flower (c), and part of another: d, section of bracts or leaves of the involucre.

To prove that this is the. case, we have only to compare such a corolla (that of Coreopsis, Fig. 220, c, or one from the Succory, for instance) with that of the Cardinal-flower, or of any other Lobelia, which is equally split down along one side ; and this again with the less irregular corolla of the Woodbine, par- tially split down on one side. LESSON XVI. ESTIVATION, OR THE ARRANGEMENT OF THE CALYX AND CO- ROLLA IN THE BUD. 279. ESTIVATION or Prcefloration relates to the way in which the leaves of the flower, or the lobes of the calyx or corolla, are placed with respect to each other in the bud. This is of some importance in distinguishing different families or tribes of plants, being generally very uniform in each. The aestivation is best seen FIG. 221. Compound flowers, i. e. beads of flowers, of Succory, LESSON 16.] THEIR ARRANGEMENT IN THE BUD. 109 by making a horizontal slice of the flower-bud when just ready to open ; and it may be expressed in diagrams, as in Fig. 223, 224. 280. The pieces of the calyx or the corolla either overlap each other in the bud, or they do not. When they do not, the aestivation is commonly Yah-ate, as it is called when the pieces meet each other by their abrupt edges without any infolding or overlapping ; as the calyx of the Linden or Basswood (Fig. 223) and the Mallow, and the corolla of the Grape, Virginia Creeper, &c. Or it may be Induplicate, which is valvate with the margins of each piece pro- jecting inwards, or involute (like the leaf in Fig. 152), as in the calyx of Virgin's-Bower and the corolla of the Potato, or else Reduplicate, like the last, but the margins projecting outwards instead of inwards ; these last being mere vari- ations of the valvate form. 281. When the pieces overlap in the bud, it is in one of two ways : either every piece has one edge in and one edge out ; or some pieces are wholly outside and others wholly inside. In the first case the cestivation is Convolute or twisted, as in the corolla of Geranium (most com- monly, Fig. 224), Flax (Fig. 191), and of the Mallow Family. Here one edge of every petal covers the next before it, while its other edge is covered by the next behind it. In the second case it is Imbricated or imbricate, or breaking joints, like shingles on a roof, as in the calyx of Ge- ranium (Fig. 224) and of Flax (Fig. 191), and the corolla of the Linden (Fig. 223). In these cases the parts are five in number; and the regular way then is (as in the calyx of the figures above cited) to have two pieces en- tirely external (1 arid 2), one (3) with one edge covered by the first, while the other edge covers that of the adjacent one on the other side, and two (4 and 5) wholly within, their margins at least being covered by the rest. That is, they just represent a circle of five leaves spirally arranged on the five-ranked or f plan (187, 188, and Fig. 143 - 145), only with the stem shortened so as to bring the parts close together. The spiral arrangement of the parts of FIG. 223. Section across the flower-bud of Linden. FIG. 224. Section across the flower-bud of Geranium : the sepals numbered in their order- 10 110 ARRANGEMENT OF PARTS IN THE BUD. [LESSON 16. the blossom is the same as that of the foliage, — an additional evi- dence that the flower is a sort of branch. The petals of the Linden, with only one outside and one inside, as shown in Fig. 223, exhibit a gradation between the imbricated and the convolute modes. When the parts are four in number, generally two opposite ones overlap the other two by both edges. When three in number, then one is outer- most, the next has one edge out and the other covered, and the third is within, being covered by the other two; as in Fig. 190. This is just the three-ranked (£) spiral arrangement of leaves (186, and Fig. 171). 282. In the Mignonette, and some other flowers, the aestivation is open ; that is, the calyx and corolla are not closed at all over the other parts of the flower, even in the young bud. 283. When the calyx or the corolla is tubular, the shape of the tube in the bud has sometimes to be considered, as well as the way the lobes are arranged. For example, it may be Plaited or plicate, that is, folded lengthwise ; and the plaits may either be turned outwards, forming projecting ridges, as in the corolla of Campanula ; or turned inwards, as in the corolla of the Gentian, &c. When the plaits are wrapped round all in one direc- tion, so as to cover one another in a convolute manner, the aestivation is said to be Supervolute, as in the corolla of Stramonium (Fig. 225) and the Morning- Glory ; and in the Morning- Glory it is twisted besides. FIG. 225. Upper part of the corolla of a Stramonium (Datura meteloides), in the bud. Underneath is a cross-section of the same. LESSON 17.] THE STAMENS. Ill LESSON XVII. MORPHOLOGY OF THE STAMENS. 284. THE STAMENS exhibit nearly the same kinds of variation in different species that the calyx and corolla do. They may be dis- tinct (that is, separate from each other, 267) or united. They may be/ree (269), or else coherent with other parts : this concerns 285. Their Insertion, or place of attachment, which is most com- monly the same as that of the corolla. So, stamens are Hypogynous (269), when they are borne on the receptacle, or axis of the flower, under the pistils, as they naturally should be, and as is shown in Fig. 212. Perigynous, when borne on (that is coherent below with) the calyx ; as in the Cherry, Fig. 213. Epigynous, when borne on the ovary, appar- ently, as in Fig. 216. To these we may add Gynandrous (from two Greek words, answer- / A 'jMjJh - »tig. ing to "stamens and pistil united"), when the stamens are consolidated with the style, so as to be borne by it, as in the Lady's Slipper (Fig. 226) and all the Orchis Family. Also Epipetalous (meaning on the petals), when ey are borne by the corolla ; as in Fig. 194, and in most monopetalous blossoms. As to 286. Their Union With each Other, the stamens may be united by their filaments or by their anthers. In the former case they are Monadelphous (from two Greek words, meaning " in one brother- hood "), when united by their filaments into one set, usually into a ring or cup below, or into a tube, as in the Mallow Family, the Passion-flower, and the Lupine (Fig. 228). Diadelphous (in two brotherhoods), when so united in two sets, as in the Pea and almost all papilionaceous flowers (275) : here the stamens are nine in one set, and one in the other (Fig. 227). FIG. 226. Style of a Lady's Slipper (Cypripediurn), and stamens united with it : a, a, the anthers of the two good stamens ; st., an abortive stamen, what should be its anther changed into a petal-like body ; stig., the stigma. 112 THE STAMENS. [LESSON 17. Triadelphous, in three sets or parcels, as in the common St. Johns- wort ; or Polyadelphous, when in more numerous sets, as in the Loblolly Bay, where they are in five clusters. On the other hand, stamens are said to be Syngenesious, when united by their an- thers (Fig. 229, 230), as they are in Lobelia, in the Violet (slightly), and in what are called compound flowers, such as the Thistle, Sunflower, Coreopsis (Fig. 220), and Suc- cory (Fig. 222). In Lobelia, and in the Squash and Pumpkin, the stamens are united both by their anthers and their filaments. 287. Their Number in the flower is sometimes expressed by terms compounded of the Greek numerals and the word used to signify stamen ; as, monandrous, for a flower having only one stamen ; diandrous, one with two stamens ; triandrous, with three stamens ; te- trandrous, with four stamens ; pentandrous, with five stamens ; and so on, up to polyan- druus (meaning with many stamens), when there are twenty or a larger number, as in a Cactus (Fig. 197). All such terms may be found in the Glossary at the end of the book. 288. Two terms are used to express particular numbers with un, equal length. Namely, the stamens are didynamous when only four in number, two longer than the other two, as in the Mint, Catnip, Gerardia (Fig. 194), Trumpet-Creeper, &c. ; and tetradynamous, when they are six, with four of them regularly longer than the other two, as in Mustard (Fig. 188), and all that family. 2SO. Their Parts. As already shown (233), a stamen consists of two part?, the Filament and the Anther (Fig. 231). 290. The Filament is a kind of stalk to the anther : it is to the anther nearly what the petiole is to the blade of a leaf. Therefore it is not an essential part. As a leaf may be without a stalk, so the anther may be sessile, or without a filament. When present, ifSlG. 227. Diadelphous stamens of the Pea, &c. 228. Monadelphous stamens of the Lupine. FIG. 229.

LESSON 17.] THEIR STRUCTURE AND PARTS. 113 the filament may be of any shape ; but it is commonly thread-like, as in Fig. 231, 234, &c. 291. The Anther is the essential part of the stamen. It is a sort of case, filled with a fine powder, called Pollen, which serves to fertilize the pistil, so that it may perfect seeds. The anther may be considered, first, as to 292. Its Attachment to the filament. Of this there are three ways ; namely, the anther is Innate (as in Fig. 232), when it is attached by its base to the very apex of the filament, turning neither inwards nor outwards ; or Adnate (as in Fig. 233), when at- tached by one face, usually for its whole length, to the side of the fila- ment ; and Versatile (as in Fig. 234), when fixed by its middle only to the very point of the filament, so as to swing loosely, as we see it in the Lily, in Grasses, &c. 293. In both the last-named cases, 232 233 234 the anther either looks inwards or out- wards. When it is turned inwards, or is fixed to that side of the filament which looks towards the pistil or centre of the flower, the anther is incumbent or introrse, as in Magnolia and the Water-Lily. When turned outwards, or fixed to the outer side of the filament, it is extrorse, as in the Tulip-tree. 294. Its Structure, &c. There are few cases in which the stamen ,rs any resemblance to a leaf. Nevertheless, the botanist's idea of a stamen is, that it answers to a leaf developed in a peculiar form and for a special purpose. In the filament he sees the stalk of the leaf ; in the anther, the blade. The blade of a leaf consists of two similar sides ; so the anther consists of two lobes or cells, one answer- ing to the left, the other to the right, side of the blade. The two lobes are often connected by a prolongation of the filament, which answers to the midrib of a leaf • this is called the connective. It is very con- spicuous in Fig. 23*2, where the connective is so broad that it separates e two cells of the anther to some distance from each other. FIG. 231. A stamen : a, filament ; b, anther discharging pollen. FIG. 232. Stamen of Isopyrum, with innate anther. 233. Of Tulip-tree, with adnate (and extrorse) anther. 234. Of Evening Primrose, with versatile anther. 10* - 114 THE STAMENS. [LESSON 17. 295. To discharge the pollen, the anther opens (or is dehiscejit) at maturity, commonly by a line along the whole length of each cell, and which answers to the margin of the leaf (as in Fig. 231) ; but when the anthers are extrorse, this line is often on the outer face, arid when introrse, on the inner face of each cell. Sometimes the anther opens only by a chink, hole, or pore at the top, as in the Azalea, Pyrola or False Wintergreen (Fig. 235), &c. ; and sometimes a part of the face separates as a sort of trap-door (or valve), hinged at the top, and opening to allow the escape of the pollen, as in the Sassafras, Spice-bush, and Barberry (Fig. 236). Most anthers are really four-celled when young ; a slender partition running lengthwise through each cell and dividing it into two compartments, one answering to the upper, and the other to the lower, layer of the green pulp of the leaf. Oc- casionally the anther becomes one-celled. This takes place mostly by confluence, that is, the two cells running together into one, as they do slightly in Pentstemon (Fig. 237) and thoroughly in the Mallow Family (Fig. 238). But sometimes it occurs by the obliteration or disappear- ance of one half of the anther, as in the Globe Ama- ranth of the gardens (Fig. 239). 296. The way in which a stamen is supposed to be constructed out of a leaf, or rather on the plan of a leaf, is shown in Fig. 240, an ideal figure, the lower part representing a stamen with the top of its anther cut away ; the upper, the corresponding upper part of a leaf. — The use of the anther is to produce Pollen, This is the powder, or fine dust, commonly of a yel- low color, which fills the cells of the anther, and is discharged during blossoming, after which the stamens generally fall off or wither away.

LESSON 17.] POLLEN. 1J5 Under the microscope it is found to consist of grains, usually round or oval, and all alike in the same species, but very different in different plants. So that the plant may sometimes be recognized from the pollen alone. 298. A grain of pollen is made up of two coats ; the outer coat thickish, but weak, and frequently adorned with lines or bands, or studded with points ; the inner coat is extremely thin and delicate, birt extensible, and its cavity is filled with a thickish fluid, often rendered turbid by an immense number of minute grains that float in it. When wet, the grains absorb the water and swell so much that many kinds soon burst and discharge their contents. 299. Figures 241-250 represent some common sorts of pollen, magnified one or two hundred diameters, viz. : — A pollen-grain of the Musk Plant, spirally grooved. One of Sicyos, or One-seeded Cucumber, beset with bristly points and marked by smooth bands. One of the Wild Balsam- Apple (Echinocystis), grooved lengthwise.

MORPHOLOGY OF PISTILS. 300. THE PISTIL, when only one, occupies the centre of the flower ; when there are two pistils, they stand facing each other in the centre of the flower ; when several, they commonly form a ring or circle ; and when very numerous, they are generally crowded in rows or spiral lines on the surface of a more or less enlarged or elongated receptacle. 301. Their number in a blossom is sometimes expressed, in Sys- tematic Botany, by terms compounded of the Greek numerals and the Greek word used to signify pistil, in the following way. A flower with one pistil is said to be monogynous ; with two, digynous ; with three, trigynous ; with four, tetragynous ; with five, pentagynous, and so on ; with many pistils, polygynous, — terms which are explained in the Glossary, but which there is no need to commit to memory. 302. The Parts Of a Pistil, as already explained (234), are the Ovary, the Style, and the Stigma. The ovary is one essential part : it contains the rudiments of seeds, called Ovules. The stigma at the summit is also essential : it receives the pollen, which fertilizes the ovules in order that they may become seeds. But the style, the tapering or slender column commonly borne on the summit of the ovary, and bearing the stigma on its apex or its side, is no more neces- sary to a pistil than the filament is to the stamen. Accordingly, there is no style in many pistils : in these the stigma is sessile, that is, rests directly on the ovary. The stigma is very various in shape and appearance, being sometimes a little knob (as in the Cherry, Fig. 213), sometimes a small point, or small surface of bare, moist tissue (as in Fig. 254-256), and sometimes a longitudinal crest or line (as in Fig. 252, 258, 267, 269), and also exhibiting many other shapes. 303. The pistil exhibits an almost infinite variety of forms, and many complications. To understand these, it is needful to begin with the simple kinds, and to proceed gradually to the complex. And, first of all, the student should !. The Plan or Ideal Structure of the Pistil, or, in other words, of the way in which a simple pistil answers to a leaf. Pistils are either LESSON 18.] SIMPLE PISTILS. 117 simple or compound. A simple pistil answers to a single leaf. A compound pistil answers to two or more leaves combined, just as a monopetalous corolla (263) answers to two or more petals, or leaves of the flower, united into one body. In theory, accordingly, 305^ The Simple Pistil, Or Carpel (as it is sometimes called), consists of the blade of a leaf, curved until the margins meet and unite, form- ing in this way a closed case or pod, which is the ovary. So that the upper face of the altered leaf answers to the inner surface of the ovary, and the lower, to its outer surface. And the ovules are borne on what answers to the united edges of the leaf. The tapering sum- mit, rolled together and prolonged, forms the style, when there is any ; and the edges of the altered leaf turned outwards, either at the tip or along the inner side of the style, form the stigma. To make this perfectly clear, compare a leaf folded together in this way (as in Fig. 251) with a pistil of a Garden Pceony, or Larkspur, or with that in Fig. 252 ; or, later in the season, notice how these, as ripe pods, split down along the line formed by the united edges, and open out again into a sort of leaf, as in the Marsh- Marigold (Fig. 253). In the Double- flowering Cherry the pistil occasion ally is found changed back again into a small green leaf, partly folded, much as in Fig. 251. 306. Fig. 172 represents a simple pistil on a larger scale, th& ovary cut through to show how the ovules (when numerous) are attached to what answers to the two margins of the leaf. The Stonecrop (Fig. 168) has five such pistils in a circle, each with the side where the ovules are attached turned to the centre of the flower. 307. The line or seam down the inner side, which answers to the united edges of the leaf, and bears the ovules, is called the ventral or inner Suture. A corresponding line down the back of the ovary, and which answers to the middle of the leaf, is named the dorsal or outer Suture. 308. The ventral suture inside, where it projects a little into the FIG. 251. A ^eaf rolled up inwards, to show how the pistil is supposed to be formed. FIG. 252. Pistil of Isopyrum biternatum cut across, with the inner suture turned towards the eye. FIG. 253. Pod or ripe pistil of the Caltha, or Marsh-Marigold, after opening. 118 THE PISTILS. [LESSON 18. cavity of the ovary, and bears the ovules, is called the Placenta, Obviously a simple pistil can have but one placenta ; but this is in its nature double, one half answering to each margin of the leaf. And if the ovules or seeds are at all numerous, they will be found to occupy two rows, one for each margin, as we see in Fig. 252, 172, in the Marsh-Marigold, in a Pea-pod, and the like. 309. A simple pistil obviously can have but one cavity or cell ; except from some condition out of the natural order of things. But the converse does not hold true : all pistils of a single cell are not simple. Many compound pistils are one-celled. 310. A simple pistil necessarily has but one style. Its stigma, however, may be double, like the placenta, and for the same reason (305) ; and it often exhibits two lines or crests, as in Fig. 252, or it may even be split into two lobes. 311. The Compound Pistil consists of two, three, or any greater number of pistil-leaves, or carpels (305), in a circle, united into one body, at least by their ovaries. The Culti- vated Flax, for exam- ple (Fig. 212), has a compound pistil com- posed of five simple ones with their ovaries united, while the five styles are separate. •254 5255 ESS But in one of our wild species of Flax, the styles are united into one also, for about half their length. So the Common St. John's-wort of the fields has a compound ovary, of three united carpels, but the three styles are separate (Fig. 255), while some of our wild, shrubby species have the styles also combined into one (Fig. 256), although in the fruit they often split into three again. Even the ovaries may only partially combine with each other, as we see in different species of Saxifrage, some having their two pistils nearly separate, while in others they FIG, 254. Pistil of a Saxifrage, of two simple carpels or pistil-leaves, united at the base only, cut across both above and below. FIG. 255. Compound pistil of common St. John's-wort, cut across : styles separate. FIG. 256. The same of shrubby St. John's-wort ; the three styles united into one. LESSON 18.] COMPOUND PISTILS. 119 are joined at the base only, or else below the middle (as in Fig. 254), and in some they are united quite to the top. 312. Even when the styles are all consolidated into one, the stig- mas are often separate, or enough so to show by the number of their lobes how many simple pistils are combined to make the compound one. In the common Lily, for instance, the three lobes of the stigma, as well as the three grooves down the ovary, plainly tell us that the pistil is made of three combined. But in the Day-Lily the three lobes of the stigma are barely discernible by the naked eye, and in the Spiderwort (Fig. 257) they are as perfectly united into one as the ovaries and styles are. Here the number of cells in the ovary alone shows that the pistil is compound. These are all cases of 313. Compound Pistils with two or more Cells, namely, with as many cells as there are simple pistils, or carpels, that have united to compose the organ. They are just what would be formed if the simple pistils (two, three, or five in a circle, as the case may be), like those of a Pseony or Stonecrop, all pressed together in the centre of the flower, Were to cohere by their contiguous parts. 314. As each simple ovary has its placenta, or seed- bearing line (308), at the inner angle, so the resulting compound ovary has as many axile placenta (that is, as many placentas in the axis or centre) as there are pistil-leaves in its composition, but all more or less consolidated into one. This is shown in the cross-sections, Fig. 254-256, &c. 315. The partitions (or Dissepiments, as they are technically named) of a compound ovary are accordingly part of the walls or the sides of the carpels which compose it. Of course they are double, one layer belonging to each carpel ; and in ripe pods they often split into the two layers. 316. We have described only one, though the commonest, kind of compound pistil. There are besides 317. One-celled Compound Pistils, These are of two sorts, those with axile, and those with parietal placentae. That is, first, where the ovules or seeds are borne in the axis or centre of the ovary, and, secondly, where they are borne on its walls. The first of these ises, or that FIG. 257. Pistil of Spiderwort (Tradescantia) : the three-celled ovary cut across. 120 THE PISTILS. [LESSON 18. 318. With a Free Central Placenta, is what we find in Purslane (Fig. 214), and in most Chickweeds (Fig. 258, 259) and Pinks. The difference between this and the foregoing case is only that the delicate partitions have very early vanished ; and traces of them may often be detected. Or sometimes this is a variation of the mode 319. With Parietal Placentae, namely, with the ovules and seeds borne on the sides or wall (parietes^) of the ovary. The pistil of the Prickly Poppy, Bloodroot, Violet, Frost-weed (Fig. 261), Gooseberry, and of many Hypericums, are of this sort. To understand it perfectly, we have only to imagine two, three, or any number of carpel-leaves (like that of Fig. 251), arranged in a circle, to unite by their 259 contiguous edges, and so form one ovary or pod (as we have endeavored to show in Fig. 260) ; — very much as in the Stramonium (Fig. 199) the five petals unite by their edges to compose a mono- petalous corolla, and the five sepals to form a tubular calyx. Here each carpel is an open leaf, or partly open, bearing ovules along its margins ; and each placenta consists of the contiguous margins of two pistil-leaves grown together. 320. All degrees occur between this and the sev- eral-celled ovary with the placentae in the axis. Com- pare, for illustration, the common St. John's-worts, Fig. 255 and 256, with Fig. 262, a cross-section of the ovary of a different species, in which the three large placentae meet in the axis, but scarcely unite, and with Fig. 263, a similar section of the ripe pod of the same plant, showing three parietal placenta? borne on imperfect partitions projecting a little way into the general cell. Fig. 261 is the same in plan, but with hardly any trace of partitions ; that is, the united edges of the leaves only slightly project into the cell. FIG. 258. Pistil of a Sandwort, with the ovary divided lengthwise; and 259, the same divided transversely, to show the free central placenta. FIG. SCO.

FIG. 261. Cross-section of the ovary of Frost-weed (Hcliauthcmmn), with three parietal placentae bearing ovuk-s. LESSON 18.] OPEN PISTILS. 121 321. The ovary, especially when compound, is often covered by and united with the tube of the calyx, as has already been explained (272). We describe this by saying either " ovary adherent," or " calyx adherent," &c. Or we say " ovary inferior" when the tube of the calyx is adherent throughout to the surface of the ovary, so that its lobes, and all the rest of the flower, appear to be borne on its summit, as in Fig. 215 and Fig. 216; or "half- inferior" as in the Purslane (Fig. 214), where the calyx is adherent part way up ; or " superior" where the calyx and the ovary are not combined, as in the Cherry (Fig. 213) and the like, that is, where these parts are free. The term " ovary superior," therefore, means just the same as " calyx inferior " ; and " ovary inferior," the same as " calyx superior." 322. Open or Gymnospermous Pistil, This is what we have in the whole Pine family, the most peculiar, and yet the simplest, of all pistils. While the ordinary simple pistil in the eye of the botanist represents a leaf rolled together into a closed pod (305), those of the Pine, Larch (Fig. 264), Cedar, and Arbor- Vitse (Fig. 265, 266) are plainly open leaves, in the form of ^ scales, each bearing two or more ovules on the inner face, next the base. At the time of blossoming, these pistil-leaves of the young cone diverge, and the pollen, so abundantly shed from the staminate blossoms, falls di- rectly upon the exposed ovules. Afterwards the scales close over each other until the seeds are ripe. Then they separate again, that the seeds may be shed. As their ovules and seeds are not enclosed in a pod, all such plants are said to be Gymnospermous, that is, naked-seeded. FIG. 262. Cross-section of the ovary of Hypericum graveolens. 263.

These are the bodies which are to become seeds. They are either sessile, that is, stalkless, or else borne on a stalk, called the Funiculus. They may be produced along the whole length of the cell, or only at some part of it, generally either at the top or the bottom. In the former case they are apt to be numerous ; in the latter, they may be few or single (solitary, Fig. 267 - 2G9). As to their direction, ovules are said to be Horizontal, when they are neither turned upwards nor down- wards, as in Fig. 252, 261 ; Ascending, when rising obliquely upwards, usually from the side of the cell, not from its very base, as in the Buttercup (Fig. 267), and the Purslane (Fig. 214) ; Erect, when rising upright from the base of the cell, as in the Buck- wheat (Fig. 268) ; Pendulous, when hanging from towards the top, as in the Flax (Fig. 212); and Suspended, when hanging perpendicularly from the very sum- mit of the cell, as in the Anemone (Fig. 269), Dogwood, &c. All these terms equally apply to seeds. 324. An ovule consists of a pulpy mass of tissue, the Nucleus or kernel, and usually of one or two coats. In the nucleus the embryo is formed, and the coats become the skin or coverings of the seed. There is a hole ( Orifice or Foramen) through the coats, at the place which answers to the apex of the ovule. The part by which the ovule is attached is its base ; the point of attachment, where the ripe seed breaks away and leaves a scar, is named the Hilum. The place where the coats blend, and cohere with each other and with the nucleus, is named the Chalaza. We will point out these parts in illustrating the four principal kinds of ovule. These are not difficult to understand, although ovules are usually so small that a good mag- nifying-glass is needed for their examination. Moreover, their names, all taken from the Greek, are unfortunately rather formidable. 325. The simplest sort, although the least common, is what is called the Orthotropous, or straight ovule. The Buckwheat affords a good FIG. 2G7. Section of the ovary of a Buttercup, lengthwise, showing ita ascending ovule. FIG. 268, Section of the ovary of Buckwheat, showing the erect ovule. FIG. 269. Section of the ovary of Anemone, showing its suspended ovule. LESSON 18.] OVULES. 123 instance of it : it is shown in its place in the ovary in Fig. 268, also detached in Fig. 270, and a much more magnified diagram of it in Fig. 274. In this kind, the orifice (/) is at the top, the chalaza and the hilum (c) are blended at the base or point of attachment, which is at the opposite end ; and the axis of the ovule is straight. /._.. If such an ovule were to grow on one side more than on the other, and double up, or have its top pushed round as it enlarges, it would become a Campylotropous or curved ovule, as in Cress and Chickweed (Fig. 271). Here the base remains as in the straight kind, but its apex with the orifice is brought round close to it. — Much the most com- mon form of all is the Anatropous or inverted ovule. This is shown in Fig. 267, and 273 ; also a much enlarged section lengthwise, or diagram, in Fig. 275. To understand it, we have only to suppose the first sort (Fig. 270) to be inverted on its stalk, or rather to have its stalk bent round, applied to one side of the ovule lengthwise, and to grow fast to the coat down to near the orifice (jf) ; the hilum, therefore, where the seed-stalk is to break away (h), is close to the orifice ; but the chalaza (c) is here at the top of the ovule ; between it and the hilum runs a ridge or cord, called the Rhaphe (r), which is simply that part of the stalk which, as the ovule grew and turned over, adhered to its surface. — Lastly, the Amphitropous or half-anatropous ovule (Fig. 272) differs from the last only in having a shorter rhaphe, ending about half-way between the chalaza and the orifice. So the hilum or attachment is not far from the middle of one side, while the chalaza is at one end and the orifice at the other. 326.

MORPHOLOGY OF THE RECEPTACLE. THE RECEPTACLE (also called the Torus) is the axis, or stem, which the leaves and other parts of the blossom are attached to (231). It is commonly small and short (as in Fig. 1GO) ; but it sometimes occurs in more conspicuous and remarkable forms. 328. Occasionally it is elongated, as in some plants of the Caper family (Fig. 276), making the flower really look like a branch, hav- ing its circles of leaves, stamens, &c., separated by long spaces or internodes. 329. The Wild Geranium or Cranesbill has the receptacle pro- longed above and between the insertion of the pistils, in the form of a slender beak. In the blossom, and until the fruit is ripe, it is concealed by the five pistils united around it, and their flat stylos covering its whole surface (Fig. 277). But at maturity, the five small and one-seeded fruits separate, and so do their stylos, from the beak, and hang suspended from the summit. They split off elasti- LESSON 19.] THE RECEPTACLE. 125 cally from the receptacle, curving upwards with a sudden jerk, which scatters the seed, often throwing it to a considerable distance. 330. When a flower bears a great many pis- tils, its receptacle is gen- erally enlarged so as to give them room ; some- times becoming broad and flat, as in the Flow- ering Raspberry, some- times elongated, as in the Blackberry, the Mag- nolia, &c. It is the re- ceptacle in the Straw- berry (Fig. 279), much enlarged and pulpy when ripe, which forms the eatable part of the fruit, and bears the small seed-like pistils on its surface. In the Rose (Fig. 280), instead of being convex or conical, the receptacle is deeply con- cave, or urn-shaped. Indeed, a Rose-hip may be likened to a strawberry turned inside out, like the finger of a glove reversed, and the whole covered by the adherent tube of the calyx, which remains beneath in the strawberry. 331. A Disk is a part of the re- ceptacle, or a growth from it, en- larged under or around the pistil. It is hypogynous (269), when free from all union either with the pistil or the calyx, as in the Rue and the Orange (Fig. 281). It is perigy- nous (270), when it adheres to the 281 base of the calyx, as in the Bladder-nut and Buckthorn (Fig. 28 2", FIG. 27G.

Often it adheres both to the calyx and to the ovary, as in New Jersey Tea, the Apple, &c., consolidating the whole together. In such cases it is sometimes carried up and expanded on the top of the ovary, as in the Parsley and the Ginseng families, when it is said to be epigynous (273). 332. In Nelumbium, — a large Water-Lily, abounding in the wa- ters of our Western States, — the singular and greatly enlarged receptacle is shaped like a top, and bears the small pistils immersed in separate cavities of its flat upper surface (Fig. 284). LESSON XX. THE FRUIT. 333. THE ripened ovary, with its contents, becomes the Fruit. When the tube of the calyx adheres to the ovary, it also becomes a part of the fruit : sometimes it even forms the principal bulk of it, as in the apple and pear. (^3^i Some fruits, as they are commonly called, are not fruits at :ill in the strict botanical sense. A strawberry, for example (as we have just seen, 330, Fig. 282), although one of the choicest fruits in the common acceptation, is only an enlarged and pulpy receptacle, hearing the real fruits (that is, the ripened pistils) scattered over its FIG. 282.

And mulberries, figs, and pine-apples are masses of many fruits with a pulpy flower-stalk, &c. Passing these by for the present, let us now consider only 335. Simple Fruits, These are such as are formed by the ripening of a single pistil, whether simple (305) or compound (311). 336. A simple fruit consists, then, of the Seed-vessel (technically called the Pericarp), or the Avails of the ovary matured, and the seeds, contained in it. Its structure is generally the same as that of the ovary, but not always ; because certain changes may take place after flowering. The commonest change is the obliteration in the growing fruit of some parts which existed in the pistil at the time of flowering. The ovary of a Horsechestnut, for instance, has three cells and two ovules in each cell ; but the fruit never has more than three seeds, and rarely more than one or two, and only as many cells. Yet the vestiges of the seeds that have not matured, and of the wanting cells of the pod, may always be detected in the ripe fruit. This oblitera- tion is more complete in the Oak and Chestnut. The ovary of the first likewise has three cells, that of the second six or seven cells, each with two ovules hanging from the summit. We might there- fore expect the acorn and the chestnut to have as many cells, and two seeds in each cell. Whereas, in fact, all the cells and all the ovules but one are uniformly obliterated in the forming fruit, which thus becomes one-celled and one-seeded, and rarely can any vestige be found of the missing parts. 337. On the other hand, a one-celled ovary sometimes becomes several-celled in the fruit by the formation of false partitions, com- monly by cross-partitions, as in the jointed pod of the Sea-Rocket and the Tick-Trefoil (Fig. 304). 338. Their Kinds, In defining the principal kinds of simple fruits which have particular names, we may classify them, in the first place, into, — 1. Fleshy Fruits-, 2. Stone Fruits-, and 3. Dry Fruits. The first and second are of course indekiscent ; that is, they do not split open when ripe to discharge the seeds. 339. In fleshy fruits the whole pericarp, or wall of the ovary, thickens and becomes soft (fleshy, juicy, or pulpy) as it ripens. Of this the leading kind is 340. The Berry, such as the gooseberry and currant, the blueberry d cranberry, the tomato, and the grape. Here the whole flesh is equally soft throughout. The orange is merely a berry with a thery rind. mis and 128 THE FRUIT. [LESSON 20. /-\ 341. The Pepo, or Gourd-fruit, is the sort of berry which belongs to the Gourd family, mostly with a hard rind and the inner portion softer. The pumpkin, squash, cucumber, and melon are the prin- cipal examples. 342. The Pome is a name applied to the apple, pear, and quince ; fleshy fruits like a berry, but the principal thickness is calyx, only the papery pods arranged like a star in the core really belonging to the pistil itself (333). 343. Secondly, as to fruits which are partly fleshy and partly hard, one of the most familiar kinds is 344. The Drupe, or Stone-fruit ; of which the cherry, plum, and peach (Fig. 285) are familiar examples. In this the outer part of the thickness of the pericarp becomes fleshy, or softens, like a berry, while the inner hardens, like a nut. From the way in which the pistil is con- structed (305), it is evident that the fleshy part here answers to the lower, and the stone to the upper, side of the leaf; — a leaf always consisting of two layers of green pulp, an upper and an under layer, which are considerably different (439). 345. Whenever the walls of a fruit are separable into two layers, the outer layer is called the Exocarp, the inner, the Endocarp (from Greek words meaning "outside fruit" and " inside fruit"). But in a drupe the outer portion, being fleshy, is likewise called Sarcocarp (which means "fleshy fruit"), and the inner, the Putamen or stone. The stone of a peach, and the like, it will be perceived, belongs to the fruit, not to the seed. When the walls are separable into three layers, the outer layer is named either exocarp or Epicarp ; the middle one is called the Mesocarp (i. e. middle fruit) ; and the inner- most, as before, the Endocarp. ."•16. Thirdly, in dry fruits the seed-vessel remains herbaceous in texture, or becomes thin and membranaceous, or else it hardens throughout. Some forms remain closed, that is, are indehiscent (338) ; others are dehiscent, that is, split open at maturity in some regular way. Of indehiscent or closed dry fruits the principal kinds are the following. 347. The Achcnilim, or Akene, is a small, one-seeded, dry, indehis- FIG. 285. Longitudinal section of a poach, showing the flesh, the stone, and the seed. LESSON 20.] ITS KINDS. 129 cent fruit, such as is popularly taken for a naked seed : but it is plainly a ripened ovary, and shows the re- mains of its style or stigma, or the place sss from which it has fallen. Of this sort are the fruits of the Buttercup (Fig. 286, 287), the Cinque-foil, and the Strawberry (Fig. 279, 288) ; that is, the real fruits, botanically speaking, of the latter, which are taken for seeds, not the large juicy receptacle on the surface of which they rest (330). Here the akenes are simple pistils (305), very numerous in the same flower, and forming a head of such fruits. In the Nettle, Hemp, &c., there is only one pistil to each blossom. 348. In the raspberry and blackberry, each grain is a similar pistil, like that of the strawberry in the flower, but ripening into a miniature stone-fruit, or drupe. So that in the strawberry we eat the receptacle, or end of the flower-stalk ; in the rasp- berry, a cluster of stone-fruits, like cherries on a very small scale ; and in the blackberry, both a juicy receptacle and a cluster of stone-fruits covering it (Fig. 289, 290). 349. The fruit of the Composite family is also an achenium. Here the surface of the ovary is covered by an adherent calyx-tube, as is evident from the position of the corolla, apparently standing on its summit (321, and Fig. 220, a). Sometimes the limb or divisions of the calyx are entirely wanting, as in Mayweed (Fig. 291) and White weed. Sometimes the limb of the calyx forms a crown or cup on the top of the achenium, as in Succory (Fig. 292); in Coreopsis, it often takes the form of two blunt teeth or scales ; in the Sunflower (Fig. 293), it consists of two FIG. 286.

This is called the Pappus ; — a name which properly means the down like that of the Thistle ; but it is applied to all these forms, and to every other under which the limb of the calyx of the " compound flowers " appears. In Lettuce, Dandelion (Fig. 29G), and the like, the achenium as it matures tapers upwards into a slender beak, like a stalk to the pappus. 350. A Utricle is the same as an achenium, but with a thin and bladdery loose pericarp ; like that of the Goosefoot or Pigweed (Fig. 297). When ripe it bursts open irregularly to discharge the seed ; or sometimes it epens by a circular line all round, the upper part falling off like a lid ; as in the Amaranth (Fig. 298). 351. A Caryopsis, or Grain, differs from the last only in the seed adhering to the thin pericarp throughout, so that fruit and seed are in- corporated into one body; as in wheat, In- dian corn, and other kinds of grain. 352. A Ntlt is a dry and indehiscent fruit, commonly one-celled and one-seeded, with a hard, crus- taceous, or bony wall, such as the cocoanut, hazelnut, chestnut, and the acorn (Fig. 21, 299). Here the involucre, in the form of a cup at the base, is called the Cvpule. In the Chestnut it forms the bur ; in the Hazel, a leafy husk. FIG. 291. Achenium of Mayweed (no pappus). 292.

A Samara, Or Key-fruit, is either a nut or an achenium, or any other indehiscent fruit, furnished with a wing, like that of the Maple (Fig. 1), Ash (Fig. 300), and Elm (Fig. 301). 354. The Capsule, or Pod, is the general name for dry seed-vessels which split or burst open at maturity. But several sorts of pod are distin- guished by particular names. Two of them belong to simple pistils, namely, the Follicle and the Legume. 355. The Follicle is a fruit of a simple pistil opening along the inner suture (307). The pods of the Preony, Col- umbine, Larkspur, Marsh-Marigold (Fig. 302), and Milkweed are of this kind. The seam along which the follicle opens answers to the edges of the pistil-leaf (Fig. 251, 253). 35 G. The Legume or true Pod, like the Pea-pod (Fig. 303), is similar to the follicle, only it opens by the outer as well as the inner or ventral suture (307), that is, by what answers to the midrib as well as by what answers to the united margins of the leaf. It splits therefore into two pieces, which are called valves. The le- gume belongs to plants of the Pulse family, which are accordingly termed Leguminosce, that is, leguminous plants. So the fruits of this family keep the name of legume, whatever their form, and whether they open or not. A legume divided across into one-seeded joints, which separate when ripe, as in Tick-Trefoil (Fig. 304), is named a Lament. 357. The true Capsule is the pod of a compound pistil. Like the ovary it resulted from, it may be one-celled, or it may have as many cells as there are carpels in its composition. It may discharge its seeds through chinks or pores, as in the Poppy, or burst irregularly in some part, as in Lobelia and the Snapdragon ; but commonly it splits open (or is dehiscent) lengthwise into regular pieces, called valves.

Dehiscence of a pod resulting from a compound pistil, when regular, takes place in one of two principal ways, which are best shown in pods of two or three cells. Either the pod splits open down the middle of the back of each cell, when the dehiscence is loculicidal, as in Fig. 305 ; or it splits through the partitions, after which each cell ft generally opens at its inner angle, when it is septicidal, as in Fig. 306. These names are of Latin derivation, the first meaning " cutting into the cells " ; the second, " cut- ting through the partitions." Of the first sort, the Lily and Iris (Fig. 305) are good examples ; of the second, the Rhododen- dron, Azalea, and St. John's-wort. From the structure of the pistil (305-311) the student will readily see, that the line down the back of each cell answers to the dorsal suture of the carpel ; so that the pod opens by this when loculicidal, while it separates into its component carpels, which open as follicles, when septicidal. Some pods open both ways, and so split into twice as many valves as the carpels of which they are formed. 359. In loculicidal dehiscence the valves naturally bear the par- titions on their middle ; in the septicidal, half the thickness of a partition is borne on the margin of each valve. See the diagrams, Fig. 307-309. A variation of either mode sometimes occurs, as 307 shown in the diagram, Fig. 309, where the valves break away from the partitions. This is called septifragal dehiscence ; and may be seen in the Morning-Glory. SCO. Three remaining sorts of pods are distinguished by proper names, viz. : — FIG. 305. Capsule of Iris (with loculicidal dehiscence), below cut across. FIG. 306. Pod of a Marsh St. John's-wort, with septicidal dehiscence. FIG, 307. Diagram of septicidal ; 308, of loculicidal ; and 309, of septifragal dehiscence. LESSON 20.] MULTIPLE FRUITS. 133 361. The Silique (Fig. 310), the peculiar pod of the Mustard fam- ily ; which is two-celled by a false partition stretched across between two parietal placentas. It generally opens by two valves from below upwards, and the placentae with the partition are left behind when the valves fall off. 362. A Siliele or Pouch is only a short and broad silique, like that of the Shepherd's Purse, of the Candy-tuft, &c. 363. The Pyxis is a pod which opens by a circular hori- zontal line, the upper part forming a lid, as in Purslane (Fig. 311), the Plantain, Hen- bane, &c. In these the dehiscence extends all round, or is circumcissile. So it does in Fig. 298, which represents a sort of one- seeded pyxis. In Jeffersonia or Twin-leaf, the line does not separate quite round, but leaves a portion to form a hinge to the lid. 364. Multiple OF Collective Fruits (334) are, properly speaking, masses of fruits, resulting from several or many blossoms, aggre- gated into one body. The pine-apple, mulberry, Osage-orange, and the fig, are fruits of this kind. This latter is a peculiar form, how- ever, being to a mulberry nearly what a Rose-hip is to a strawberry (Fig. 279, 280), namely, with a hollow receptacle bearing the flowers concealed inside ; and the whole eatable part is this pulpy common receptacle, or hollow thickened flower-stalk. 365. A Strobile, or Cone (Fig. 314), is the pe- culiar multiple fruit of Pines, Cypresses, and the like ; hence named Coniferce, viz. cone- bearing plants. As already shown (322), these cones are made of open pistils, mostly in the form of flat scales, regularly overlying each other, and pressed together in a spike or head. 31* s13 Each scale bears one or two naked seeds on its inner face. When the cone is ripe and dry, the scales turn back or diverge, and the seed peels off and falls, generally carrying with it a wing, which was a part of the lining of the scale, and which facilitates the dispersion of the seeds by the wind (Fig. 312, 313). In Arbor-Vita?, the scales FIG. 310. Silique of Spring Cress (Cardamine rhomboidea), opening. FIG. 311. The pyxis, or pod, of the common Purslane. FIG. 312.

[LESSON 21. of the small cone are few, and not very unlike the leaves (Fig. 265). In Cypress they are very thick at the top and narrow at the base, so as to make a peculiar sort of closed cone. In Juniper and Red Ce- dar, the few scales of the very small cone become fleshy, and ripen into a fruit which might be taken for a berry. LESSON XXL THE SEED. 366. THE ovules (323), when they have an embryo (or unde- veloped plantlet, 16) formed in them, become seeds. 367. The Seed, like the ovule from which it originates, consists of its coats, or integuments, and a kernel. 36§. The Seed-COatS are commonly two (324), the outer and the inner. Fig. 315 shows the two, in a seed cut through lengthwise. The outer coat is often hard or crustaceous, whence it is called the Testa, or shell of the seed ; the inner is thin and delicate. 369. The shape and the markings, so various in dif- ferent seeds, depend mostly on the outer coat. Sometimes it fits FIG. 314. Cone of Pitch-Pino (Pinus rigida). FIG. 315.

We cannot divide them into similar smaller parts having the prop- erties of the whole, as we may any mineral body. We may cut them in pieces ; but the pieces are only mutilated parts of a cell. This is a peculiarity of organic things (2, 3) : it is organic structure. Being composed of cells, the main structure of plants is called 393. Cellular Tissue, The cells, as they multiply, build up the tissues or fabric of the plant, which, as we have said (389), may be likened to a wall or an edifice built of bricks, or still better to a honeycomb composed of ranges of cells (Fig. 340). 394. The walls of the cells 'are united where they touch each other ; and so the partition appears to be a simple membrane, although it is really double ; as may be shown by boiling the tissue a few minutes and then pulling the parts asunder. And in soft fruits the cells separate in ripening, although they were perfectly united into a tissue, when green, like that of Fig. 340. 395. In that figure the cells fit together perfectly, leaving no interstices, except a very small space at some of the corners. But in most leaves, the cells are loosely heaped together, leaving spaces or passages of all sizes (Fig. 356) ; and in the leaves and stems of aquatic and marsh plants, in particular, the cells are built up into narrow partitions, which form the sides of large and regular canals or passages (as shown in Fig. 341). These passages form the holes or cavities so conspicuous on cutting across any of these plants, and which are always filled with air. They may be likened to a stack of chimneys, built up of cells in place of bricks. 396. When small and irregular, the interstices are called inter- cellular spaces (that is, spaces between the cells). When large and regular, they are named intercellular passages or air-passages. 397. It will be noticed that in slices of the root, stem, or any tissue where the cells are not partly separate, the boundaries of the cells are usually more or less six-sided, like the cells of a honeycomb ; and this is apt to be the case in whatever direction the slice is made, whether crosswise, lengthwise, or obliquely. The reason of this is easy to see. The natural figure of the cell is globular. Cells which are not pressed upon by others are generally round or roundish (except when they grow in some particular direction), as we see in the green pulp of many leaves. When a quantity of spheres (such, for instance, as a pile of cannon-balls) are heaped up, each one in the interior of the heap is touched by twelve others. If the spheres be 144 VEGETABLE FABRIC. [LESSON 23. soft and yielding, as young cells are, when pressed together they will become twelve-sided, like that in Fig. 339. And a section in any direction will be six-sided, as are the meshes in Fig. 340. (398. The size of the common cells of plants varies from about the thirtieth to the thousandth of an inch in diameter. An ordinary size is from -yfa to -5^ of an inch ; so that there may generally be from 27 to 125 millions of cells in the compass of a cubic inch ! ll'.i'J. Now when it is remembered that many stems shoot up at the rate of an inch or two a day, and sometimes of three or four inches, knowing the size of the cells, we may form some conception of the rapidity of their formation. 'The giant Puff-ball has been known to enlarge from an inch or so to nearly a foot in diameter in a single night ; but much of this is probably owing to expansion. "We take therefore a more decisive, but equally extraordinary case, in the huge flowering stem of the Century-Plant. After waiting many years, or even for a century, to gather strength and materials for the effort, Century-Plants in our conservatories send up a flow- ering stalk, which grows day after day at the rate of a foot in twenty- four hours, and becomes about six inches in diameter. This, sup- posing the cells to average ^^ of an inch in diameter, requires the formation of over twenty thousand millions of cells in a day ! 400. The walls of the cells are almost always colorless. The green color of leaves and young bark, and all the brilliant hues of flowers, are due to the contents of the cells, seen through their more or less transparent walls. 401. At first the walls are always very thin. In all soft parts they remain so ; but in other cases they thicken on the inside and harden, as we see in the stone of stone-fruits, and in all hard wood (Fig. 345). Sometimes this thickening continues until the cell is nearly filled up solid. 402. The walls of cells are perfectly closed and whole, at least in all young and living cells. Those with thickened walls have thin places, indeed ; but there are no holes opening from one cell into another. And yet through these closed cells the sap and all the juices are conveyed from one end of the plant to the other. 403. Vegetable cells may vary widely in shape, particularly when not combined into a tissue or solid fabric. The hairs of plants, for example, are cells drawn out into tubes, or are composed of a row of cells, growing on the surface. Cotton consists of simple long hairs on the coat of the seed ; and these hairs are single cells. The hair- LESSON 24.] WOOD. 145 like bodies which abound on young roots are very slender projec- tions of some of the superficial cells, as is seen in Fig. 337. Even the fibres of wood, and what are called vessels in plants, are only peculiar forms or transformations of cells. LESSON XXIV. VEGETABLE FABRIC I WOOD. 404. CELLULAR, TISSUE, such as described in the last Lesson, makes up the whole structure of all very young plants, and the whole of Mosses and other vegetables of the lowest grade, even when full grown. But this fabric is too tender or too brittle to give needful strength and toughness for plants which are to rise to any considerable height and support themselves. So all such plants have also in their composition more or less of 405. Wood, This is found in all common herbs, as well as in shrubs and trees ; only there is not so much of it in proportion to the softer cellular tissue. It is formed very early in the growth of the root, stem, and leaves ; traces of it appearing in large embryos even while yet in the seed. 406. Wood is likewise formed of cells, — of cells which at first are just like those that form the soft parts of plants. But early in their growth, some of these lengthen and at the same time thicken their walls ; these are what is called Woody Fibre or Wood- Cells ; others grow to a greater size, have thin walls with various markings upon them, and often run together end to end so as to form pretty FIG 341. Part of a slice across the stem of the Calla, or rather Richardia Africana, magnified. 13 146 VEGETABLE FABRIC. [LESSON 24. I large tubes, comparatively ; these are called Ducts, or sometimes Vessels. Wood almost always consists of both woody fibres and ducts, ^ 343 345 variously intermingled, and combined into bundles or threads which run lengthwise through the root and stem, and are spread out to form the frame- work of the leaves (13G). In trees and shrubs they are so numerous and crowded together, that they make a 6 solid mass of wood. In herbs they are fewer, and often scattered. That is all the difference. 407. The porosity of some kinds of wood, which is to be seen by the naked eye, as in mahogany and Oak-wood, is owing to a large sort of ducts. These generally contain air, except in very * young parts, and in the spring of the year, when they are often gorged with sap, as we see in a wounded Grape- vine, or in the trunk of a Sugar-Maple at that time. But in woody plants through the season, the sap is usually carried up from the roots to the leaves 9V* by the 408. Wood-Cells, OF Woody Fibre, (Fig. 342-345.) These are small tubes, commonly between one and two thousandths, but in Pine-wood sometimes two or three hundredths, of an inch in diam- eter. Those from the tough bark of the Basswood, shown in Fig. 342, are only the fifteen-hundredth of an inch wide. Those of But- ton wood (Fig. 345) are larger, and are here highly magnified be- sides. They also show the way wood-cells are commonly put to- gether, namely, with their tapering ends overlapping each other, — spliced together, as it were, — thus giving more strength and tough- ness to the stem, &c. FIG. 342. Two wood-cells from the inner or fibrous bark of the Linden or Basswood. 343. Some tissue of the wood of the same, viz. wood-cells, and below ( additions to the wood and bark remain as a permanent portion of the tree, or until destroyed by decay, the foliage is tem- porary, the crop of leaves being annually thrown off after they have served their purpose. l->7. Structure of the Leaf, Leaves also consist both of a woody and a cellular part (135). The woody part is the framework of ribs and veins, which have already been described in full (136-147), LESSON 25.] AND LEAVES. 155 They serve not only to strengthen the leaf, but also to bring in the ascending sap, and to distribute it by the veinlets throughout every part. The cellular portion is the green pulp, and is nearly the same as the green layer of the bark. So that the leaf may properly enough be regarded as a sort of expansion of the fibrous and green layers of the bark. It has of course no corky layer ; but the whole is covered by a transparent skin or epidermis, resembling that of the stem. 438. The green pulp consists of cells of various forms, usually loosely arranged, so as to leave many irregular spaces, or air-pas- sages, communicating with each other throughout the whole interior of the leaf (Fig. 356). The green color is owing to a peculiar green matter lying loose in the - cells, in form of minute grains, named Chlorophyll (i. e. the green of "=^1 — -, — ,, — ... — ir-jr-w ' leaves). It is this substance, seen through the transparent walls of the cells where it is accumulated, which gives the common green hue to vege- tation, and especially to foliage. 439. The green pulp in most leaves forms two principal layers ; an upper one, facing the sky, and an under one, facing the ground. The upper one is always deeper green in color than the lower. This is partly owing, perhaps, to a greater amount of chlorophyll in the upper cells, but mainly to the more compact arrangement of these cells. As is seen in Fig. 356 and 357, the cells of the upper side are oblong or cylin- drical, and stand endwise to the surface of the leaf, usually close to- gether, leaving hardly any vacant spaces. Those of the lower part of the leaf are apt to be irregular in shape, most of them with their longer diameter parallel to the face of the leaf, and are very loosely arranged, leaving many and wide air-chambers. The green color underneath is therefore diluted and paler. 440. In many plants which grow where they are subject to drought, and which hold -their leaves during the dry season (the Oleander for example), the greater part of the thickness of the leaf consists of layers of long cells, placed endwise and very much com- FIG. 356. Section through the thickness of a leaf of the Star- Anise (Illiciuni), of Florida, magnified. The upper and the lower layers of thick-walled and empty cells represent the epidermis or skin. All those between are cells of the green pulp, containing grains of chlorophyll. 156 ANATOMY OF THE LEAVES. [LESSON 25. pacted, so as to expose as little surface as possible to the direct action of the hot sun. On the other hand, the leaves of marsh plants, and of others not intended to survive a drought, have their cells more loosely arranged throughout. In such leaves the epidermis, or skin, is made of only one layer of cells ; while in the Oleander, and the like, it consists of three or four layers of hard and thick-walled cells. In all this, therefore, we plainly see an arrangement for tempering the action of direct sunshine, and for restraining a too copious evap- oration, which would dry up and destroy the tender cells, at least when moisture is not abundantly supplied through the roots. 441. That the upper side of the leaf alone is so constructed as to bear the sunshine, is shown by what happens when their position is reversed : then the leaf soon twists on its stalk, so as to turn again its under surface away from the light ; and when prevented from doing so, it perishes. 442. A large part of the moisture which the roots of a growing plant are constantly absorbing, after being carried up through the stem, is evaporated from the leaves. A Sunflower-plant, a little over three feet high, and with between five and six thousand square inches of surface in foliage, &c., has been found to exhale twenty or thirty ounces (between one and two pints) of water in a day. Some part of this, no doubt, flies off through the walls of the epidermis or skin, at least in sunshine and dry weather ; but no considerable por- tion of it. The very object of this skin is to restrain evaporation. The greater part of the moisture exhaled escapes from the leaf through the 443. StomatCS or Breathing-pores, These are small openings through the epidermis into the air-chambers, establishing a direct commu- nication between the whole interior of the leaf and the external air. Through these the vapor of water and air can freely escape, or enter, as the case may be. The aperture is guarded by a pair of thin-walled cells, — resembling those of the green pulp within,— which open when moist so as to allow exhalation to go on, but promptly close when dry, so as to arrest it before the interior of the leaf is injured by the dryness. 444. Like the air-chambers, the breathing-pores belong mainly to the under side of the leaf. In the White Lily, — where they are unusually large, and easily seen by a simple microscope of mod- erate power, — there are about 60,000 to the square inch on the epidermis of the lower surface of the leaf, and only about 3,000 in LESSON 26. J THE PLANT IN ACTION. 157 the same space of the upper surface. More commonly there are few or none on the upper side ; direct sunshine evidently being unfavor- able to their operation. Their immense numbers make up for their minuteness. They are said to vary from less than 1,000 to 170,000 to the square inch of surface. In the Apple-tree, where they are under the average as to number, there are about 24,000 to the square inch of the lower surface ; so that each leaf has not far from 100,000 of these openings or mouths. LESSON XXVI. THE PLANT IN ACTION, DOING THE WORK OF VEGETATION. 445. BEING now acquainted with the machinery of the plant, we naturally proceed to inquire what the use of it is, and how it works. 44(>. It has already been stated, in the first of these Lessons (7), that the great work of plants is to change inorganic into organic matter ; that is, to take portions of earth and air, — of mineral mat- ter, — upon which animals cannot live at all, and to convert them FIG. 357. Portion of a White-Lily leaf, cut through and magnified, showing a section of the thickness, and also a part of the skin of the lower side, with some breathing-pores- 14 158 THE PLANT IN ACTION. [LESSON 26. into something upon which they can live, namely, into food. All the food of all animals is produced by plants. Animals live upon vegetables ; and vegetables live upon earth and air, principally upon the air. 447. Plants feed upon Earth and Air, This is evident enough from the way in which they live. Many plants will flourish in pure sand or powdered chalk, or on the bare face of a rock or wall, watered merely with rain-water. And almost any plant may be made to grow from the seed in pure sand, and increase its weight many times, even if it will not come to perfection. Many naturally live suspended from the branches of trees high in the air, and nourished by it alone, never having any connection with the soil (81) ; and some which naturally grow on the ground, like the Live-for-ever of the gardens, when pulled up by the roots and hung in the air will often flourish the whole summer long. 448. It is true that fast-growing plants, or those which produce considerable vegetable matter in one season, — especially in such a concentrated form as to be useful as food for man or the higher animals, — will come to maturity only in an enriched soil. But what is a rich soil ? One which contains decomposing vegetable matter, or some decomposing animal matter ; that is, in either case, some decomposing organic matter formerly produced by plants ; aided by this, grain-bearing and other important vegetables will grow more rapidly and vigorously, and make a greater amount of nourishing matter, than they could if left to do the whole work at once from the beginning. So that in these cases also all the organic matter was made by plants, and made out of earth and air. 449. Their Chemical Composition shows what Plants arc made of, The soil and the air in which plants live, and by which they are every- where surrounded, supply a variety of materials, some likely to be useful to the plant, others not. To know what elements the plant makes use of, we must first know of what its fabric and its products are composed. 4")0. We may distinguish two sorts of materials in plants, one of which is absolutely essential, and is the same in all of them ; the other, also to some extent essential, but very variable in different plants, or in the same plant under different circumstances. The former is the organic, the latter the inorganic or eartlnj materials. •r>i. The Earthy or Inorganic Constituents, If we burn thoroughly a leaf, a piece of wood, or any other part of a vegetable, almost all of LESSON 26.] ITS CHEMICAL COMPOSITION. 159 it is dissipated into air. But a little ashes remain : these represent the earthy constituents of the plant. 452. They consist of some potash (or soda if a marine plant was used), some silex (the same as flint), and probably a little lime, al- umine, or magnesia, iron or manganese, sulphur or phosphorus, &c. Some or all of these elements may be detected in many or most plants. But they make no part of their real fabric ; and they form only from one or two to nine or ten parts out of a hundred of any vegetable substance. The ashes vary according to the nature of the soil. In fact, they consist, principally, of such materials as happened to be dissolved, in small quantity, in the water which was taken up by the roots ; and when that is consumed by the plant, or flies off pure (as it largely does, 447) by exhalation, the earthy mat- ter is left behind in the cells, — just as it is left incrusting the sides of a teakettle in which much hard water has been boiled. As is very natural, therefore, we find more earthy matter (i. e. more ashes) in the leaves than in any other part (sometimes as much as seven per cent, when the wood contains only two per cent) ; because it is through the leaves that most of the water escapes from the plant. These earthy constituents are often useful to the plant (the silex, for instance, increases the strength of the Wheat-stalk), or are useful in the plant's products as furnishing needful elements in the food of man and other animals ; and some must be held to be necessary to vege- tation, since this is never known to go on without them. 453. The Organic Constituents, As has just been remarked, when we burn in the open air a piece of any plant, nearly its whole bulk, and from 88 to more than 99 parts out of a hundred by weight of its substance, disappear, being turned into air and vapor. These are the organic constituents which have thus been consumed, — the actual materials of the cells and the whole real fabric of the plant. And we may state that, in burning, it has been decomposed into ex- actly the same kinds of air, and the vapor of water, that the plant used in its making. The burning has merely undone the work of vegetation, and given back the materials to the air just in the state in which the plant took them. 454. It will not be difficult to understand what the organic con- stituents, that is, what the real materials, of the plant are, and how the plant obtains them. The substance of which vegetable tissue, viz. the wall of the cells, is made, is by chemists named Cellulose. It is just the same thing in composition in wood and in soft cellular tis- 160 THE PLANT IN ACTION. [LESSON 26. sue, — in the tender pot-herb and in the! oldest tree. It is composed of carbon, hydrogen, and oxygen, 12 parts of the former to 10 of each of the two latter. These, accordingly, are necessary materials of vegetable growth, and must be received by the growing plant. 455. The Plant's Food must contain these three elements in some shape or other. Let us look for them in the materials which the plant is constantly taking from the soil and the air. 4"x'i. Water is the substance of which it takes in vastly more than of anything else : we well know how necessary it is to vegetable life. The plant imbibes water by the roots, which are specially construct- ed for taking it in, as a liquid when the soil is wet, and probably also in the form of vapor when the soil is only damp. That water in the form of vapor is absorbed by the leaves likewise, when the plant needs it, is evident from the way partly wilted leaves revive and freshen when sprinkled or placed in a moist atmosphere. Now water is composed of hydrogen and oxygen, two of the three elements of cellulose or plant-fabric. Moreover, the hydrogen and the oxygen exist in water in exactly the same proportions that they do in cellu- lose : so it is clear that water furnishes these two elements. 457. We inquire, therefore, after the third element, carbon. This is the same as pure charcoal. Charcoal is the carbon of a vegetable left behind after charring, that is, heating it out of contact of the air until the hydrogen and oxygen are driven off. The charcoal of wood is so abundant in bulk as to preserve perfectly the shape of the cells after charring, and in weight it amounts to about half that of the original material. Carbon itself is a solid, and not at all dissolved by water : as such, therefore, it cannot be absorbed into the plant, however minute the particles ; only liquid and air can pass through the walls of the cells (402, 410). It must therefore come to the plant in some combination, and in a fluid form. The only substance within the plant's reach containing carbon in the proper state is 45Si Carbonic Acid. This is a gas, and one of the components of the atmosphere, everywhere making about J-^TT part of its bulk, i— enough for the food of plants, but not enough to be injurious to animals. For when mixed in any considerable proportion with the air we breathe, carbonic acid is very poisonous. The air produced by burning charcoal is carbonic acid, and we know how soon burning charcoal in a close room will destroy life. 459.' The air around us consists, besides this minute proportion of carbonic acid, of two other gases, mixed together, viz. oxygen LESSON 26.] ITS FOOD. 161 and nitrogen. The nitrogen gas does not support animal life : it only dilutes the oxygen, which does. It is the oxygen gas alone which renders the air fit for breathing. 460. Carbonic acid consists of carbon combined with oxygen. In breathing, animals are constantly forming carbonic acid gas by unit- ing carbon from their bodies with oxygen of the air ; they inspire oxygen into their lungs ; they breath it out as carbonic acid. So with every breath animals are diminishing the oxygen of the air, — so necessary to animal life, — and are increasing its carbonic acid, — so hurtful to animal life ; or rather, which would be so hurtful if it were allowed to accumulate in the air. The reason why it does not increase in the air beyond this minute proportion is that plants feed upon it. They draw their whole stock of carbon from the carbonic acid of the air. 461. Plants take it in by their leaves. Every current, or breeze that stirs the foliage, brings to every leaf a succession of fresh atoms of carbonic acid, which it absorbs through its thousands of breathing- pores. We may prove ,this very easily, by putting a small plant or a fresh leafy bough into a glass globe, exposed to sunshine, and hav- ing two openings, causing air mixed with a known proportion of carbonic acid gas to enter by one opening, slowly traverse the foliage, and pass out by the other into a vessel proper to receive it : now, examining the air chemically, it will be found to have less carbonic acid than before. A portion has been taken up by the foliage. 462. Plants also take it in by their roots, some probably as a gas, in the same way that leaves absorb it, and much, certainly, dissolved in the water which the rootlets imbibe. The air in the soil, es- pecially in a rich soil, contains many times as much carbonic acid as an equal bulk of the atmosphere above. Decomposing vegetable matter or manures, in the soil, are constantly evolving carbonic acid, and a large part of it remains there, in the pores and crevices, among which the absorbing rootlets spread and ramify. Besides, as this gas is dissolved by water in a moderate degree, every rain-drop that falls from the clouds to the ground brings with it a little carbonic acid, dissolving or washing it out of the air as it passes, and bringing it down to the roots of plants. And what flows off inU the streams and ponds serves for the food of water-plants. 463J So water and carbonic acid, taken in by the leaves, or taken in by the roots and carried up to the leaves as crude sap, are the general food of plants, — are the raw materials out of which at least 14* 162 THE PLANT IN ACTION, [LESSON 26. the fabric and a part of the general products of the plant are made. Water and carbonic acid are mineral matters : in the plant, mainly in the foliage, they are changed into organic matters. This is 464. The Plant's proper Work, Assimilation, viz. the conversion by the vegetable of foreign, dead, mineral matter into its own living sub- stance, or into organic matter capable of becoming living substance. To do this is, as we have said, the peculiar office of the plant. How and where is it done ? 465. It is done in the green parts of plants alone, and only when these are acted upon by the light of the sun. The sun in some way supplies a power which enables the living plant to originate these peculiar chemical combinations, — to organize matter into forms which are alone capable of being endowed with life. The proof of this proposition is simple ; and it shows at the same time, in the simplest way, what the plant does with the water and carbonic acid it consumes. Namely, 1st, it is only in sunshine or bright daylight that the green parts of plants give out oxygen gas, — then they do ; and 29, the giving out of this oxygen gas is just what is required to render the chemical composition of water and carbonic acid the same as that of cellulose (454), that is, of the plant's fabric. This shows why plants spread out so large a surface of foliage. 466. In plants growing or placed under water we may see bubbles of air rising from the foliage ; we may collect enough of this air to test it by a candle's burning brighter in it ; which shows it to be oxygen gas. Now if the plant is making cellulose or plant-substance, — that is, is making the very materials of its fabric and growth, as must generally be the case, — all this oxygen gas given off by the leaves comes from the decomposition of carbonic acid taken in by the plant. 467. This must be so, because cellulose is composed of 10 parts of oxygen and 10 of hydrogen to 12 of carbon (454) : here the first two are just in the same proportions as in water, which consists of one part of oxygen and one of hydrogen, — so that 10 parts of water and 12 of carbon represent one of cellulose or plant-fabric ; and to make it out of w:' r and carbonic acid, the latter (which is composed of carbon air1 oxygen) has only to give up all its oxygen. In other words, the plant, in its foliage under sunshine, decomposes carbonic n; 5 1 gas, and turns the carbon together with water into cellulose, at the same time giving the oxygen off into the air. 468. And we can readily prove that it is so, — namely, that plants ,ESSON 26.] PRODUCING ORGANIC MATTER. 163 do decompose carbonic acid in their leaves and give out its oxygen, — by the experiment mentioned in paragraph 461. There the leaves, as we have stated, are taking in carbonic acid gas. We now add, that they are giving out oxygen gas at the same rate. The air as it comes from the glass globe is found to have just as much more oxygen as it has less carbonic acid than before — just as much more oxygen as would be required to turn the carbon rer tained in the plant back into carbonic acid again. 4G9. It is all the same when plants — instead of making fabric at once, that is, growing — make the prepared material, and store it up for future use. The principal product of plants for this purpose is Starch, which consists of minute grains of organic matter, lying loose in the cells. Plants often accumulate this, perhaps in the root, as in the Turnip, Carrot, and Dahlia (Fig. 57- 60) ; or in subter- ranean stems or branches, as in the Potato (Fig. 68), and many rootstocks ; or in the bases of leaves, as in the Onion, Lily (Fig. 73-75), and other bulbs ; or in fleshy leaves above ground, as those of the Ice-Plant, House-leek, and Century-Plant (Fig. 82) ; or in the whole thickened body, as in many Cactuses (Fig. 76) ; or in the seed around the embryo, as in Indian Corn (Fig. 38, 39) and other grain ; or even in the embryo itself, as in the Horsechestnut (Fig. 23, 24), Bean (Fig. 16), Pea (Fig. 19), &c. In all these forms this is a provision for future growth, either of the plant itself or of some offset from it, or of its offspring, as it springs from the seed. Now starch is to cellulose or vegetable fabric just what the prepared clay is to the potter's vessel, — the same thing, only requiring to be shaped and consolidated. It has exactly the same chemical composition, and is equally made of carbon and the elements of water, by decomposing the same amount of carbonic icid and giving back its oxygen to the air. In using it for growth, plant dissolves it, conveys it to the growing parts, and consoli- dates it into fabric. 470. Sugar, another principal vegetable product, also has essen- tially the same chemical composition, and may be formed out of the same common food of plants, with the same result. The different dnds of sugar (that of the cane, &c. and of grapes) consist of the ime three materials as starch and cellulose, only with a little more water. The plant generally forms the sugar out of starch, changing one into the other with great ease ; starch being the form in which prepared material is stored up, and sugar that in which it is ex- 164 THE PLANT PURIFYING THE AIR, [LESSON 26. pended or transferred from one part of the plant to another. In the Sugar-cane and Indian Corn, starch is deposited in the seed ; in ger- mination this is turned into sugar for the plantlet to begin its growth with ; the growing plant produces more, and deposits some as starch in the stalk ; just before blossoming, this is changed into sugar again, and dissolved in the sap, to form and feed the flowers (which cannot, like the leaves, create nourishment for themselves) ; and what is left is deposited in the seed as starch again, with which to begin the same operation in the next generation. 471. We might enumerate other vegetable products of this class (such as oil, acids, jelly, the pulp of fruits, &c.), and show how they are formed out of the carbonic acid and water which the plant takes in. But those already mentioned are sufficient. In producing any of them, carbonic acid taken from the air is decomposed, its carbon retained, and its oxygen given back to the air. That is to say, 472. Plants purify the Air for Animals, by taking away the carbonic acid injurious to them, continually poured into it by their breathing, as well as by the burning of fuel and by decay, and restoring in its place an equal bulk of life-sustaining oxygen (4GO). And by the same operation, combining this carbon with the elements of water, &c., and elaborating them into organic matter, — especially into starch, sugar, oil, and the like, — 473. Plants produce all the Food and Fabric of Animals, The herbiv- orous animals feed directly upon vegetables ; and the carnivorous feed upon the herbivorous. Neither the one nor the other originate any organic matter. They take it all ready-made from plants, — altering the form and qualities more or less, and at length destroy- ing or decomposing it. 474. Starch, sugar, and oil, for example, form a large part of the food of herbivorous animals and of man. When digested, they enter into the blood ; any surplus may be stored up for a time in the form of fat, being changed a little in its nature ; while the rest (and finally the whole) is decomposed into carbonic acid and water, and exhaled from the lungs in respiration ; — in other words, is given back to the air by the animal as the very same materials which the plant takes from the air as its food (463) ; — is given back to the air in the same form that it would have been if the vegetable matter had been left to decay where it grew, or if it had been set on fire and burned ; — and with the same result too as to the heat, the heat in this case producing and maintaining the proper temperature of the animal. LESSON 26.] AND PRODUCING THE FOOD OF ANIMALS. 165 475. But starch, sugar, and the like, do not make any part of the flesh or fabric of animals. And that for the obvious reason, that they consist of only the three elements carbon, hydrogen, and oxygen ; whereas the flesh of animals has nitrogen as well as these three ele- ments in its composition. The materials of the animal body, called Fibrine in the flesh or muscles, Gelatine in the sinews and bones, Oaseine in the curd of milk, &c., are all forms of one and the same substance, composed of carbon, hydrogen, oxygen, and nitrogen. As nitrogen is a large constituent of the atmosphere, and animals are taking it into their lungs with every breath they draw, we might suppose that they take this element of their frame directly from the air. But they do not. Even this is furnished by vegetables, and animals receive it ready-made in their food. And this brings us to consider still another and most important vegetable product, of » different class from the rest (omitted till now, for the sake of greater simplicity) ; namely, what is called 476. Proteine. This name has been given to it by chemists, be* cause it occurs under such a protean variety of forms. The Gluten of wheat and the Legumine of beans and other leguminous plants may be taken to represent it. It occurs in all plants, at least in young and growing parts. It does not make any portion of their tissue, but is contained in all living cells, as a thin jelly, mingled with the sap or juice, or as a delicate mucilaginous lining. In fact, it is formed earlier than the cell-wall itself, and the latter is moulded on it, as it were ; so it is also called Protoplasm. It disappears from common cells as they grow old, being transferred onward to new or forming parts, where it plays a very active part in growth. Mixed with starch, &c., it is accumulated in considerable quantity in wheat, beans, and other grains and seeds, especially those which are most nutritious as food. It is the proteine which makes them so nutritious. Taken by animals as food, it forms their flesh and sinews, and the animal part of their bones, without much change ; for it has the same composition, — is just the same thing, indeed, in some slightly different forms. To produce it, the plant employs, in addition to the carbonic acid and water already mentioned as its general food, some ammo- nia ; which is a compound of hydrogen and nitrogen. Ammonia (which is the same thing as hartshorn) is constantly escaping into the air in small quantities from all decomposing vegetable and animal substances. Besides, it« is produced in every thunder- storm. Every flash of lightning causes some to be made (in the 166 PLANT-LIFE. [LESSON 27. form of nitrate of ammonia) out of the nitrogen of the air and the vapor of water. The reason why it never accumulates in the air so as to be perceptible is, that it is extremely soluble in water, as are all its compounds. So it is washed out of the atmosphere by the rain as fast as it is made or rises into it, and is brought down to the roots of plants, which take it in freely. "When assimilated in the leaves along with carbon and water, proteine is formed, the very jsubstance of the flesh of animals. So all flesh is vegetable matter in its origin. >{O-< 477. Even the earthy matter of the bones, and the iron and other mineral matters in the blood of animals, are derived from the plants they feed upon, with hardly an exception. These are furnished by the earthy or mineral constituents of plants (452), and are merely accumulated in the animal frame. 478. Animals, therefore, depend absolutely upon vegetables for their being. The great object for which the All-wise Creator estab- lished the vegetable kingdom evidently is, that plants might stand on the surface of the earth between the mineral and the animal crea- tions, and organize portions of the former for the sustenance of the latter. LESSON XXVII. PLANT-LIFE. 479. LIFE is known to us only by its effects. We cannot tell what it is ; but we notice some things which it does. One peculi- arity of living things, which has been illustrated in the last Lesson, is their power of transforming matter into new forms, and thereby making products never produced in any other way. Life is also manifested by 480. Motion, that is, by self-caused movements. Living things move ; those not living are moved. Animals, living as they do upon organized food, — which is not found everywhere, — must needs have the power of going after it, of collecting it, or at least of taking it in ; which requires them to make spontaneous movements. But plants, with their wide-spread surface (34, 131) always in con- LESSON 27.] CIRCULATION IN CELLS. 167 tact with the earth and air on which they feed, — the latter and the most important of these everywhere just the same, — have no need of locomotion, and so are generally fixed fast to the spot where they grow. 481. Yet many plants move their parts freely, sometimes when there is no occasion for it that we can understand, and sometimes accomplishing by it some useful end. The sudden closing of the leaflets of the Sensitive Plant, and the dropping of its leafstalk, when jarred, also the sudden starting forwards of the stamens of the Barberry at the touch, are familiar examples. Such cases seem at first view so strange, and so different from what we expect of a plant, that these plants are generally imagined to be endowed with a pe- culiar faculty, denied to common vegetables. But a closer exam- ination will show that plants generally share in this faculty ; that similar movements may be detected in them all, only — like those of the hands of a clock, or of the shadow of a sun-dial — they are too slow for the motion to be directly seen. 482. It is perfectly evident, also, that growth requires motion ; that there is always an internal activity in living plants as well as in animals, — a power exerted which causes their fluids to move or circulate, and carries materials from one part to another. Some movements are mechanical ; but even these are generally directed or controlled by the plant. Others must be as truly self-caused as those of animals are. Let us glance at some of the principal sorts, and see what light they throw upon vegetable life. 483. Circulation ill Cells, From what we know of the anatomy of plants, it is clear that they have no general circulation (like that of all animals except the lowest), through a system of vessels opening into each other (402, 410). But in plants each living cell carries on a circulation of its own, at least when, young and active. This may be beautifully seen in the transparent stems of Chara and many other water-plants, and in the leaves of the Fresh-water Tape-Grass (Vallisneria), under a good microscope. Here the sap circulates, often quite briskly in appearance, (but the motion is magnified as well as the objects,) in a steady stream, just beneath the wall, around each cell, passing up one side, across the end, down the other, and so round to complete the circuit, carrying with it small particles, or the larger green grains, which make the current more visible. This circulation may also be observed in hairs, particularly those on flowers, such as the jointed hairs of Spiderwort, looking 168 PLANT-LIFE. [LESSON 27. under the glass like strings of blue beads, each bead being a cell. But here a microscope magnifying six or eight hundred times in diameter is needed to see the current distinctly. 484. The movement belongs to the protoplasm (476), or jelly-like matter under the cell-wall. As this substance has just the same composition as the flesh of animals, it is not so strange that it should exhibit such animal-like characters. In the simplest water-plants, of the Sea-weed family, the body which answers to the seed is at first only a rounded little mass of protoplasm. When these bodies escape from the mother plant, they often swim about freely in the water in various directions, by a truly spontaneous motion, when they closely resemble animalcules, and are often mistaken for them. After enjoying this active life for several hours, they come to rest, form a covering of cellulose, and therefore become true vegetable cells, fix themselves to some support, germinate, and grow into the perfect plant. 485. Absorption, Conveyance of the Sap, &c. Although contained in cells with closed walls, nevertheless the fluids taken in by the roots are carried up through the stem to the leaves even of the topmost bough of the tallest tree. And the sap, after its assimilation by the leaves, is carried down in the bark or the cambium-layer, and dis- tributed throughout the plant, or else is conveyed to the points where growth is taking place, or is accumulated in roots, stems, or" wherever a deposit is being stored up for future use (71, 104, 128, 4G9). 486. That the rise of the sap is pretty rapid in a leafy and growing plant, on a dry summer's day, is evident from the amount of water it is continually losing by exhalation from the foliage (447) ; — a loss which must all the while be supplied from the roots, or else the leaves would dry up and die ; as they do so promptly when sepa- rated from the stem, or when the stem is cut off from the roots. Of course they do not then lose moisture any faster than they did before the separation ; only the supply is no longer kept up from below. 487. The rise of the sap into the leaves apparently is to a great degree the result of a mode of diffusion which has been called En- dosmose. It acts in this way. Whenever two fluids of different density are separated by a membrane, whether of dead or of living substance, or are separated by any porous partition, a flow takes place through the partition, mainly towards the heavier fluid, until that is brought to the same density as the other, A familiar illus- LESSON 27.] CONVEYANCE OF THE SAP. 169 tration is seen when we place powdered sugar upon strawberries, and slightly moisten them : the dissolving sugar makes a solution stronger than the juice in the cells of the fruit ; so this is gradually drawn out. Also when pulpy fruits are boiled in a strong sirup ; as soon as the sirup becomes denser than the juice in the fruit, the latter begins to flow out and the fruit begins to shrivel. But when shrivelled fruits are placed in weak sirup, or in water, they become plump, because the flow then sets inwards, the juice in the cells being denser than the water outside. Now the cells of the living plant contain organic matter, in the form of mucilage, protoplasm, some- times sugar, &c. ; and this particularly abounds in young and growing parts, such as the tips of roots (Fig. 56), which, as is well known, are the principal agents in absorbing moisture from the ground. The contents of their cells being therefore always much denser than the moisture outside (which is water containing a little carbonic acid, &c., and a very minute quantity of earthy matter), this moisture is constantly drawn into the root. What makes it ascend to the leaves ? 488. To answer this question, we must look to the leaves, and consider what is going on there. For (however it may be in the spring before the leaves are out), in a leafy plant or tree the sap is not forced up from below, but is drawn up from above. "Water large- ly evaporates from the leaves (447) ; it flies off into the air as vapor, leaving behind all the earthy and the organic matters, — these not being volatile ; — the sap in the cells of the leaf therefore becomes denser, and so draws upon the more watery contents of the cells of the stalk, these upon those of the stem below, and so on, from cell to cell down to the root, causing a flow from the roots to the leaves, which begins in the latter, — just as a wind begins in the direction towards which it blows. Somewhat similarly, elaborated sap is drawn into buds or any growing parts, where it is consolidated into fabric, or is conveyed into tubers, roots, seeds, and the like, in which it is condensed into starch and stored up for future use (74, 103, &c.). 489. So in absorbing moisture by the roots, and in conveying e sap or the juices from cell to cell and from one part to another, e plant appears to make use of a physical or inorganic force ; but manages and directs this as the purposes of the vegetable econ- omy demand. Now, when the proper materials are brought to the wing parts, growth takes place > and in growth the plant moves 15 V • on • 170 PLANT-LIFE. [LESSON 27. the particles of matter, arranges them, and shapes the fabric in a manner which we cannot at all explain by any mechanical laws. The organs are not shaped by any external forces ; they shape themselves, and take such forms and positions as the nature of each part, or the kind of plant, requires. 490. Special Movements, Besides growing, and quite independent of it, plants not only assume particular positions, but move or bend one part upon another to do so. Almost every species does this, as well as what are called sensitive plants. In springing from the seed, the radicle or stem of the embryo, if not in the proper position already, bends itself round so as to direct its root-end downwards, and the stern-end or plumule upwards. It does the same when covered so deeply by the soil that no light can affect it, or when growing in a perfectly dark cellar. But after reaching the light, the stem bends towards that, as every one knows ; and bends towards the stronger light, when the two sides are unequally ex- posed to the sun. It is now known that the shoot is bent by the shortening of the cells on the more illuminated side ; for if we split the bending shoot in two, that side curves over still more, while the opposite side inclines to fly back. But how the light causes the cells to shorten on that side, we can no more explain, than we can tell how the will, acting through the nerves, causes the contraction of the fibres of the muscles by which a man bends his arm. We are sure that the bending of the shoot has nothing to do with growth, because it takes place after a shoot is grown ; and the del- icate stem of a young seedling will bend a thousand times faster than it grows. Also because it is yellow light that most favors growth and the formation of vegetable fabric, while the blue and violet rays produce the bending. Leaves also move, even more freely than steins. They constantly present their upper face to the light ; and when turned upside down, they twist on their stalks, or curve round to recover their original position. The free ends of twining stems, as of Hop, or Morning Glory, or Bean, which appar- ently hang over to one side from their weight, arc in fact bent over, ami, the direction of the bend constantly chaiiLrmu, the shoot is stead; Iv sweeping round the, circle, making a revolution every few hours, or even more rapidly in certain cases, until it reaches a neighboring support, when, by a continuation of the same move- ment, it twines around it. Most tendrils revolve in the same way, sometimes even more rapidly ; while others only turn from the LESSON 27.] MOVEMENTS. 171 light ; this is especially the case with those that cling to walls or trunks by sucker-like disks, as Virginia Creeper, p. 38, fig. 62. When an active tendril comes into contact with a stem or any such extraneous body, it incurves at the point of contact, and so lays hold of the support : the same contraction or tendency to curve affecting the whole length of the tendril, it soon shortens into a coil, part coil- ing one way, part the other, thus drawing the shoot up to the sup- porting body ; or, if the tendril be free, it winds up in a simple coil. This movement of tendrils is so prompt in the Star-Cucumber (Sic- yos) in Echinocystis, and in two sorts of Passion-flower, that the end, after a gentle rubbing, coils up by a movement rapid enough to be readily seen. In plants that climb by their leaf-stalks, such as Maurandia and Tropseolum, the movements are similar, but much too slow to be seen. 491. The so-called sleep of plants is a change of position as night draws on, and in different ways, according to the species, — the Locust and Wood-Sorrel turning down their leaflets, the Honey Locust raising them upright, the Sensitive Plant turning them for- wards one over another ; and the next morning they resume their diurnal position. One fact, among others, showing that the changes are not caused by the light, but by some power in the plant itself, is this. The leaves of the Sensitive Plant close long before sunset ; but they expand again before sunrise, under much less light than they had when they closed. In several plants the leaves take the nocturnal position when brushed or jarred, — in the common Sensi- tive Plant very suddenly, in other sorts less quickly, in the Honey Locust a little too slowly for us to see the motion. The way in which blossoms open and close, some when the light increases, some when it diminishes, illustrates the same thing. The stamens of the Barberry, when touched at the base on the inner side, — as by an insect seeking for honey, or by the point of a pin, — make a sudden jerk forward, and in the process commonly throw some pollen upon the stigma, which stands a little above their reach. 492. In many of these cases we plainly perceive that a useful end is subserved. But what shall we say of the Venus's Fly-trap of North Carolina, growing where it might be sure of all the food a plant can need, yet provided with an apparatus for catching insects, and actually capturing them expertly by a sudden motion, in the manner already described (12G, Fig. 81) ? Or of the leaflets of the 172 CRYPTOGAMOUS OR FLOWERLESS PLANTS. [LESSON 27. Desmodium gyrans of the East Indies, spontaneously falling and rising by turns in jerking motions nearly the whole day long ? We can only say, that plants are alive, no less than animals, and that it is a characteristic of living things to move. *#* CRYPTOGAMOUS OR FLOWERLESS PLANTS. 493. IN all the foregoing Lessons, we have had what may be called plants of the higher classes alone in view. There are others, composing the lower grades of vegetation, to which some allusion ought to be made. 494. Of this sort are Ferns or Brakes, Mosses, Liverworts, Lichens, Sea-weeds, and Fungi or Mushrooms. They are all classed together under the name of Flowerless Plants, or Crypto- gamous Plants; the former epithet referring to the fact that they do not bear real blossoms (with stamens and pistils) nor seeds (with an embryo ready-formed within). Instead of seeds they have spores, which are usually simple cells (392). The name Cryptogamous means, of hidden fructification, and intimates that they may have something answering to stamens and pistils, although not the same ; and this is now known to be the case with most of them. 495. Flowerless plants are so very various, and so peculiar in each family, that a volume would be required to illustrate them. Curious and attractive as they are, they are too difficult to be studied botanically by the beginner, except the Ferns, Club-Mosses, and Horse-tails. For the study of these we refer the student at once to the Manual of the Botany of the Northern United States, and to the field, forest, and Garden Botany. The structure and physiology of these plants, as well as of the Mosses, Liverworts, Lichens, Sea- weeds, and Fungi, are explained in the Structural Botany, or Botanical Text-Book, and in other similar works. When the student has become prepared for the study, nothing can be more interesting than these plants of the lowest orders. LESSON 28.] SPECIES AND KINDS. 173 LESSON XXVIII. SPECIES AND KINDS. 496. UNTIL now, we have been considering plants as to their structure and their mode of life. We have, as it were, been read- ing the biography of an individual plant, following it from the tiny seedling up to the mature and fruit-bearing herb or tree, and learning how it grows and what it does. The botanist also considers plants as to their relationships. 497. Plants and animals, as is well known, have two great pecu- liarities : 1st, they form themselves ; and 2d, they multiply them- selves. They reproduce themselves in a continued succession of 498. Individuals (3). Mineral things occur as masses, which are divisible into smaller and still smaller ones without alteration of their properties (391). But organic things (vegetables and ani- mals) exist as individual beings. Each owes its existence to a parent, and produces similar individuals in its turn. So each indi- vidual is a link of a chain ; and to this chain the natural-historian applies the name of 499. Species, All the descendants from the same stock therefore compose one species. And it was from our observing that the sev- eral sorts of plants or animals steadily reproduce themselves, — or, in her words, keep up a succession of similar individuals, — that the of species originated. So we are led to conclude that the Ore- established a definite number of species at the beginning, which ve continued by propagation, each after its kind. 500. There are few species, however, in which man has actually erved the succession for many generations. It could seldom be proved that all the White Pine trees or White Oaks of any forest came from the same stock. But observation having familiarized us with the general fact, that individuals proceeding from the same stock are essentially alike, we infer from their close resemblance E'Mt these similar individuals belong to the same species. That is, infer it when the individuals are as much like each other as those 5 which we know to have sprung from the same stock. 501. We do not infer it from every resemblance ; for there is the emblance of kind, — as between the White Oak and the Red Oak, "• 174 SPECIES AND KINDS. [LESSON 28. and between the latter and the Scarlet Oak : these, we take for granted, have not originated from one and the same stock, but from three separate stocks. Nor do we deny it on account of every difference ; for even the sheep of the same flock, and the plants raised from peas of the same pod, may show differences, and such differences occasionally get to be very striking. When they are pretty well marked, we call them Varieties. The White Oak, for example, presents two or three varieties in the shape of the leaves, although they may be all alike upon each particular tree. The question often arises, practically, and it is often hard to answer, whether the difference in a particular case is that of a variety, or is specific. If the former, we may commonly prove it to be so by finding such intermediate degrees of difference in various individuals as to show that no clear line of distinction can be drawn between them ; or else by observing the variety to vary back again, if not in the same individual, yet in its offspring. Our sorts of Apples, Pears, Potatoes, and the like, show us that differences which are permanent in the individual, and con- tinue unchanged through a long series of generations when propa- gated by division (as by offsets, cuttings, grafts, bulbs, tubers, &c.), are not likely to be reproduced by seed. Still they sometimes are so : and such varieties are called Races. These are strongly marked varieties, capable of being propagated by seed. Our different sorts of Wheat, Indian Corn, Peas, Radishes, &c., are familiar examples : and the races of men offer an analogous instance. 502. It should be noted, that all varieties have a tendency to be reproduced by seed, just as all the peculiarities of the parent tend to be reproduced in the offspring. And by selecting those plants which have developed or inherited any desirable peculiarity, keeping them from mingling with their less promising brethren, and selecting again the most promising plants raised from their seeds, we may in a few generations render almost any variety transmissible by seed, so long as we take good care of it. In fact, this is the way the cultivated or domesticated races, so useful to man, have been fixed and preserved. Races, in fact, can hardly, if at all, be said to exist independently of man. But man does not really produce them. Such peculiarities — often surprising enough — now and then originate, we know not how (the plant sports, as the irnrdcners say) ; they are only pre- served, propagated, and generally further developed, by the culti- ; LESSON 28.] CLASSIFICATION. 175 valor's skilful care. If left alone, they are likely to dwindle and perish, or else revert to the original form of the species. 503. Botanists variously estimate the number of known species of plants at from seventy to one hundred thousand. About 3,850 species of the higher classes grow wild in the United States east of the Mississippi. So that the vegetable kingdom exhibits a very- great diversity. Between our largest and highest-organized trees, such as a Magnolia or an Oak, and the simplest of plants, reduced to a single cell or sphere, much too minute to be visible to the naked eye, how wide the difference ! Yet the extremes are con- nected by intermediate grades of every sort, so as to leave no wide gap at any place ; and not only so, but every grade, from the most complex to the most simple, is exhibited under a wide and most beautiful diversity of forms, all based upon the one plan of vegeta- tion which we have been studying, and so connected and so an- swering to each other throughout as to convince the thoughtful botanist that all are parts of one system, works of one hand, realiza- tions in nature of the conception of One Mind. We perceive this, also, by the way in which the species are grouped into 504. Kinds, If the species, when arranged according to their re- semblances, were found to differ from one another about equally, — that is, if No. 1 differed from No. 2 just as much as No. 2 did from No. 3, and No. 4 from No. 5, and so on throughout, — then, with all the diversity in the vegetable kingdom there is now, there would yet be no foundation in nature for grouping species into kinds. Species and kinds would mean just the same thing. We should classify them, no doubt, for convenience, but our classification would be arbitrary. e fact is, however, that species resemble each other in very un- equal degrees. Some species are almost exactly alike in their whole structure, and, differ only in the shape or proportion of their parts; se, we say, belong to one Genus. Some, again, show a more gen- 1 resemblance, and are found to have their flowers and seeds con- ucted on the same particular plan, but with important differences the details ; these belong to the same Order or Family. Then, ing a wider survey, we perceive that they all group themselves er a few general types (or patterns), distinguishable at once by ir flowers, by their seeds or embryos, by the character of the ling plant, by the structure of their stems and leaves, and by their general appearance : these great groups we call Classes. Finally, we distinguish the whole into two great types or grades ; 176 SPECIES AND KINDS. ^LESSON 28. the higher grade of Flowering plant?, exhibiting the full plan of vegetation, and the lower grade of Flowerless plants, in which vegetation is so simplified that at length the only likeness between them and our common trees or Flowering plants is that they are both vegetables. From species, then, we rise first to 505. Genera (plural of Genus). The Rose kind or genus, the Oak genus, the Chestnut genus, &c., are familiar illustrations. Each genus is a group of nearly related species, exhibit ing a particular plan. All the Oaks belong to one genus, the Chestnuts to another, the Beech to a third. The Apple, Pear, and Crab are species of one genus, the Quince represents another, the various species of Haw- thorn a third. In the animal kingdom the common cat, the wild cat, the panther, the tiger, the leopard, and the lion are species of the cat kind or genus ; while the dog, the jackal, the different species of wolf, and the foxes, compose another genus. Some genera are represented by a vast number of species, others by few, very many by only one known species. For the genus may be as perfectly represented in one species as in several, although, if this were the case throughout, genera and species would of course be identical (504). The Beech genus and the Chestnut genus would be just as distinct from the Oak genus even if but one Beech and one Chestnut were known ; as in- deed was the case formerly. 506. Orders or Families (the two names are used for the same thing in botany) are groups of genera that resemble each other ; that is, they are to genera what genera are to species. As familiar illustra- tions, the Oak, Chestnut, and Beech genera, along with the Hazel genus and the Hornbeams, all belong to one order, viz. the Oak Fam- ily ; the Birches and the Alders make another family ; the Poplars and Willows, another; the Walnuts (with the Butternut) and the Hickories, another. The Apple genus, the Quince and the Haw- thorns, along with the Plums and Cherries and the Peach, the Raspberry, with the Blackberry, the Strawberry, the Rose, and many other genera, belong to a large order, the Rose Family. 507. Tribes and Suborders, This leads us to remark, that even the genera of the same order may show very unequal degrees of resem- blance. Some may be very closely related to one another, and at the same time differ strikingly from the rest in certain important partic- ulars. In the Rose Family, for example, there is the Rose genus itself, with tlu- Raspberry genus, the Strawberry, the Cinquefoil, &c. near it, but by no means so much like it as they are like each LESSON 28.] ORDERS, CLASSES, ETC. 177 other : this group, therefore, answers to what is called a Tribe ; and the Rose itself stands for another tribe. But we further observe that the Apple genus, the Hawthorns, the Quince, and the June- berry, though of the same order, and nearly related among them- selves, differ yet more widely from the Rose and its nearest relations; and so, on the other hand, do the Plum and Cherry, the Peach and the Almond. So this great Rose Family, or Order, is composed of three groups, of a more marked character than tribes, — groups which might naturally be taken for orders ; %and we call them Sub- orders. But students will understand these matters best after a few lessons in studying plants in a work describing the kinds. 508. ClasseSt These are great assemblages of orders, as already explained (515). The orders of Flowering Plants are numerous, no less than 134 being represented in the Botany of the Northern United States ; but they all group themselves under two great classes. One class comprises all that have seeds with a mono- cotyledonous embryo (32), endogenous stems (423), and generally parallel-veined leaves (139) ; the other, those with dicotyledonous embryo, exogenous stems, and netted-veined leaves ; and the whole aspect of the two is so different that they are known at a glance. 509. Finally, these two classes together compose the upper Series or grade of Flowering or Phcenogamous Plants, which have their counterpart in the lower Series of Flowerless or Cryptogamous Plants,. — composed of three classes, and about a dozen orders. 510. The universal members of classification are CLASS, ORDER^ GENUS, SPECIES, always standing in this order. When there are more, they take their places as in the following schedule, which comprises all that are generally used in a natural classification proceeding from the highest to the lowest, viz. : — Series, CLASS, Subclass, ORDER, or FAMILY, Suborder, Tribe, Subtribe, GENUS, Subgenus or Section, SPECIES, Variety. 178 BOTANICAL NAMES. [LESSON 29. LESSON XXIX. BOTANICAL NAMES AND CHARACTERS. 511. PLANTS are classified, — i. e. are marshalled under their re- spective classes, orders, tribes, genera, and species, — and they are characterized, — that is, their principal characteristics or distinguish- ing marks are described or enumerated, in order that, First, their resemblances or differences, of various degrees, may be clearly exhibited, and all the species and kinds ranked next to those they are most related to ; — and Secondly, that students may readily ascertain the botanical names of the plants they meet with, and learn their peculiarities, properties, and place in the system. 512. It is in the latter that the young student is chiefly interested. And by his studies in this regard he is gradually led up to a higher point of view, from which he may take an intelligent survey of the whole general system of plants. But the best way for the student to learn the classification of plants (or Botany as a system), is to use it, in finding out by it the name and the peculiarities of all the wild plants he meets with. 513. Names, The botanical name of a plant, that by which a botanist designates it, is the name of its genus followed by that of the species. The name of the genus or kind is like the family name or surname of a person, as Smith, or Jones. That of the species answers to the baptismal name, as John, or James. Accordingly, the White Oak is called botanically Quercus alia ; the first word, or Quercus, being the name of the Oak genus ; the second, alba, that of this particular species. And the Red Oak is named Quercus rubra ; the Black-Jack Oak, Quercus nigra ; and so on. The bo- tanical names are all in Latin (or are Latinized), this being the common language of science everywhere ; and according to the usage of that language, and of most others, the name of the species comes after that of the genus, while in English it comes before it. 514. Generic Names, A plant, then, is named by two words. The generic name, or that of the genus, is one word, and a substantive. Commonly it is the old classical name, when the genus was known to the Greeks and Romans ; as Quercus for the Oak, Fagus for the LESSON 29.] BOTANICAL NAMES. 179 Beech, Corylus, the Hazel, and the like. But as more genera be- came known, botanists had new names to make or borrow. Many- are named from some appearance or property of the flowers, leaves, or other parts of the plant. To take a few examples from the early pages of the Manual of the Botany of the Northern United States, — in which the derivation of the generic names is explained. The genus Jfepatica, p. 6, comes from the shape of the leaf resembling that of the liver. Myosurus, p. 10, means mouse-tail. Delphin- ium, p. 12, is from delphin, a dolphin, and alludes to the shape of the flower, which was thought to resemble the classical figures of the dolphin. Zanthorhiza, p. 13, is from two Greek words meaning yellow-root, the common name of the plant. Cimicifuga, p. 14, is formed of two Latin words, meaning, to drive away bugs, the same as its common name of Bugbane, the Siberian species being used to keep away such vermin. Sanguinaria, p. 26, is named from the blood-like color of its juice. 515. Other genera are dedicated to distinguished botanists or pro- moters of natural science, and bear their names : such are Magnolia, p. 15, which commemorates the early French botanist, Magnol, and Jejfersonia, p. 20, named after President Jefferson, who sent the first exploring expedition over the Rocky Mountains. Others bear the name of the discoverer of the plant in question ; as, Sarracenia, p. 23, dedicated to Dr. Sarrazin of Quebec, who was one of the first to send our common Pitcher-plant to the botanists of Europe .; and Claytonia, p. 65, first made known by the early Virginian botanist Clayton. 516. Specific Names, The name of the species is also a single word, appended to that of the genus. It is commonly an adjective, and therefore agrees with the generic name in case, gender, &c. Sometimes it relates to the country the species inhabits ; as, Clay- tonia Virginica, first made known from Virginia ; Sanguinaria Canadensis, from Canada, &c. More commonly.it denotes some obvious or characteristic trait of the species; as, for example, in Sarracenia, our northern species is named purpurea, from the pur- ple blossoms, while a more southern one is named flava, because its petals are yellow ; the species of Jeffersonia is called diphylla, meaning two-leaved, because its leaf is divided into two leaflets. Some species are named after the discoverer, or in compliment to a botanist who has made them known ; as, Magnolia Fraseri, named after the botanist Fraser, one of the first to find this species ; Ra- 180 BOTANICAL NAMES AND CHARACTERS. [LESSON 29. worthia Michauxii, p. 65, named for the early botanist Michaux ; and Polygala Nuttallii, in compliment to Mr. Nuttall, who described it under another name. Such names of persons are of course writ- ten with a capital initial letter. Occasionally some old substantive name is used for the species ; as Magnolia Umbrella, p. 49, and Ra- nunculus Flammula, p. 41. These are also written with a capital initial, and need not accord with the generic name in gender, &c. 517. The name of a variety, when it is distinct enough to require any, is made on the same plan as that of the species, and is written after it; as, Ranunculus Flammula, variety reptans, p. 41 (i. e. the creeping variety), and R. abortivus, variety micranthus, p. 42, or the small-flowered variety of this species. 518. Names of Groups, The names of tribes, orders, and the like, are in the plural number, and are commonly formed by prolonging the name of a genus of the group taken as a representative of it. For example, the order of which the Buttercup or Crowfoot genus, Ranunculus, is the representative, takes from it the name ofJRanun- culacece (Manual, p. 34) ; meaning Plantce Ranunculacece when written out in full, that is, Ranunculaceous Plants. This order comprises several tribes ; one of which, to which Ranunculus itself belongs, takes the name of Ranunculece ; another, to which the genus Clematis, or the Virgin's-Bower, belongs, takes accordingly the name of Clematidece ; and so on. So the term Rosacea (mean- ing Rosaceous plants) is the name of the order of which the Rose (Rosa) is the well-known representative ; and Rosece is the name of the particular tribe of it which comprises the Rose. 519. A few orders are named on a somewhat different plan. The great order Leguminosce, for instance (Manual, p. 123), is not named after any genus in it ; but the fruit, which is a legume (35 G), gives the name of Leguminous Plants. So, likewise, the order Umbelliferce (Manual, p. 187) means Umbelliferous or Umbel-bearing Plants; and the vast order Composite (Manual, p. 215) is so named because it consists of plants whose blossoms are crowded into heads of the sort which were called " compound flowers " by the old botanists (277). 520. Characters, The brief description, or enumeration in scien- tific terms, of the principal distinctive marks of a species, genus, order, or other group, as given in botanical works, is called its Character. Thus, in the Manual, already referred to, at the begin- LESSON 30.] HOW TO STUDY PLANTS. 181 ning, the character of the first great series is given ; then that of the first class, of the first subclass, and of the first division under it. Then, after the name of the order, follows its character (the ordinal character) : under the name of each genus (as, 1. Clematis, p. 35) is added the generic character, or description of what essentially distinguishes it ; and finally, following the name of each species, is the specific character, a succinct enumeration of the points in which it mainly differs from other species of the same genus. See, for illustration, Clematis Viorna, p. 36, where the sentence immediately following the name is intended to characterize that species from all others like it. 521. Under this genus, and generally where we have several spe- cies of a genus, the species are arranged under sections, and these often under subsections, for the student's convenience in analysis, — the character or description of a section applying to all the species under it, and therefore not having to be repeated under each species. Under Clematis, also, are two sections with names, or sub-genera, which indicates that they might almost be regarded as two distinct genera; But these details are best understood by practice, in the actual studying of plants to ascertain their name and place. And to this the student is now ready to proceed. LESSON XXX HOW TO STUDY PLANTS. 522. HAVING explained, in the two preceding Lessons, the gen- eral principles of Classification, and of Botanical Names, we may now show, by a few examples, how the student is to proceed in applying them, and how the name and the place in the system of an unknown plant are to be ascertained. 523. We suppose the student to be provided with a hand magni- fying-glass, and, if possible, with a simple microscope, i. e. with a magnifying-glass, of two or more different powers, mounted on a support, over a stage, holding a glass plate, on which small flowers or their parts may be laid, while they are dissected under the mi- croscope with the points of needles (mounted in handles), or divided 16 182 HOW TO STUDY PLANTS. [LESSON 30. by a sharp knife. Such a microscope is not necessary, except for very small flowers ; but it is a great convenience at all times, and is indispensable in studying the more difficult orders of plants. 524. We suppose the student now to have a work in which the plants of the country or district are scientifically arranged and described : if in the Southern Atlantic States, Dr. Chapman's Flora of the Southern States ; if north of Carolina and Tennessee, Gray's Manual of the Botany of the United States, fifth edition ; or, as cov- ering the whole ground as to common plants, and including also all the common cultivated plants, Gray's Field, Forest, and Garden Botany, which is particularly arranged as the companion of the present work ; that containing brief botanical descriptions of the plants, and this the explanation of their general structure, and of the technical terms employed in describing them. To express clearly the distinctions which botanists observe, and which furnish the best marks to know a plant by, requires a good many technical terms, or words used with a precise meaning. These, as they are met with, the student should look out in the Glossary at the end of this volume. The terms in common use are not so numerous as they would at first appear to be. With practice they will soon be- come so familiar as to give very little trouble. And the application of botanical descriptive language to the plants themselves, indicating all their varieties of form and structure, is an excellent discipline for the mind, equal, if not in some respects superior, to that of learn- ing a classical language. 525. The following illustrations and explanations of the way to use the descriptive work are, first, for The Field, Forest, and Garden Bot- any, that being the one which will be generally used by beginners and classes. This and the Lessons, bound together in a single compact volume, will serve the whole purpose of all but advanced students, teachers, and working botanists. Thus equipped, we proceed to 526. The Analysis of a Plant, A Buttercup will serve as well as any. Some species or other may be found in blossom throughout nearly the whole spring and summer; and, except at the very beginning of the season, the fruit, more or less developed, may be gathered with the blossom. To a full knowledge of a plant the fruit is essential, although the name may almost always be ascer- tained without it. This common yellow flower being under exam- ination, we are to refer the plant to its proper class and order or LESSON 30.] HOW TO STUDY PLANTS. 183 family. The families are so numerous, and so generally distinguish- able only by a combination of a considerable number of marks that the student must find his way to them by means of a contrivance called an Analytical Key. This Key begins on p. 12. 527. It takes note of the most comprehensive possible division of plants, namely those " producing true flowers and seeds," and those "not producing flowers, propagated by spores." To the first of these, the great series of PH^ENOGAMOUS or FLOWERING PLANTS, the plant under examination obviously belongs. 528. This series divides into those "with wood in a circle, or in concentric annual circles or layers around a central pith, netted-veined leaves, and parts of the flower mostly in fives or fours," — to which might be added the dicotyledonous embryo, but that in the present case is beyond the young student's powers, even if the fruit were at hand; — and into those " with wood in separate threads scattered through the diameter of the stem, not in a circle," also the " leaves mostly parallel-veined, and parts of the flower almost always in threes, never in fives." Although the hollowness of the stem of the present plant may obscure its internal structure, a practised hand, by throwing the light through a thin cross section of the stem under the glass, would make it evident that its woody bundles were all in a circle near the circumference, yet this could hardly be expected of an unassisted and inexperienced beginner. But the two other and very obvious marks, the netted-veined leaves, and the number five in both calyx and corolla, certify at once that the plant belongs to the first class, EXOGENOUS or DICOTYLEDONOUS PLANTS. 529. We should now look at the flower more particularly, so as to make out its general plan of structure, which we shall need to know all about as we go on. We observe that it has a calyx of 5 sepals, though these are apt to fall soon after the blossom opens ; that the 5 petals are 353 borne on the receptacle (or common axis of the flower) just above the sepals and alternate with them ; that there are next borne, a FIG. 353. A flower of a Buttercup (Ranunculus bulbosus) cut through from top to bottom, arid enlarged. 184 HOW TO STUDY PLANTS. [LESSON 30. little higher up on the receptacle, an indefinite number of stamens ; and, lastly, covering the summit or centre of the receptacle, an in- definite number of pistils. A good yiew of the whole is to be had by cutting the flower directly through the middle, from top to bottom (Fig. 358). If this be done with a sharp knife, some of the pistils will be neatly divided, or may be so by a second slicing. Each pistil, we see, is a closed ovary, containing a single ovule (Fig. 359) ascending from near the base of the cell, and is tipped with a very short broad style, which has the stigma running down the whole length of its inner edge. The ovary is little changed as it ripens into the sort of fruit termed an akene (Fig. 360) ; the ovule becoming the seed and fitting the cell (Fig. 3G1). Reverting to the key, on p. 13, we find that the class to which our plant belongs has two subclasses, one " with pistil of the ordinary sort, the ovules in a closed ovary"; the other "without proper pistil, the ovules naked on a scale," &c. The latter is nearly restricted to the Pine Family. The examination already had makes it quite clear that our plant belongs to the first subclass, ANGIOSPERMOUS Exogenous or Dicotyledonous Plants. 530. We have here no less than 110 orders under this subclass. To aid the unpractised student in finding his way among them, they are ranked under three artificial divisions ; the Polypetalous, the Munopetalous, and the Apetalous. The plant in hand being fur- nished, in the words of the key, " with both calyx and corolla, the latter of wholly separate petals," is to be sought under I. POLY- PETALOUS DIVISION; for the analysis of which, see p. 14. 531. Fully half the families of the class rank under this division. The first step in the key is to the sections A and B ; to the first of which, having "stamens more than 10, and more than twice the number of the sepals or divisions of the calyx," our plant must pertain. 532. Under this we proceed by a series of successive steps, their gradations marked by their position on the page, leading down to the name of the order or family, to which is appended the number FIG. 359.

LESSON 30.] HOW TO STUDY PLANTS. 185 of the page where that family and the plants under it are described. The propositions of the same grade, two or more, from which de- termination is to be made, not only stand one directly under the other, but begin with the same word or phrase, or with some counterpart, — in the present case again with " Stamens," and with four propositions, with one and only one of which the flower in hand should agree. It agrees with the last of the four : " Stamens not monadelphous." 533. The propositions under this, to which we are now directed, are six, beginning with the word " Pistils " or " Pistil." The one which applies to the flower in hand is, clearly, the fourth : " Pistils numerous or more than one, separate, on the receptacle." 534. The terms of the analysis directly subordinate to this are only two : we have to choose between " Stamens borne on the calyx," and " Stamens borne on the receptacle." The latter is true of our flower. The terms subordinate to this are four, beginning with the word " Leaves." The fourth alone accords : " Leaves not peltate ; herbs," — and this line leads out to the CROWFOOT FAMILY, and refers to p. 33. 535. Turning to that page, a perusal of the brief account of the marks of the RANUNCULACE^E (the technical Latin name) or CROW- FOOT FAMILY, assures us that the Key has led us safely and readily to a correct result. Knowing the order or family, we have next to ascertain the genus. Here are twenty genera to choose from ; but their characters are analyzed under sections and successive sub- sections (§, * ,•{—,-«-»•, &c.) so as to facilitate the way to the desired result. Of the two primary sections, we must reject § 1, as it agrees only in respect to the pistils, and differs wholly in the characters furnished by the sepals, the petals, and the leaves. With " § 2. Sepals imbricated in the bud: not climbing nor woody" it agrees. It also agrees with the sub-section immediately following, viz. : " * Pis- tils and akenes, several or many in a head, one-seeded" The sub- division following : " -j— Petals none: sepals petal-like,'" is inapplicable ; but its counterpart, " -i— •*— Petals and sepals both conspicuous, Jive or more : akenes, naked, short-pointed" suits, and restricts our choice to the three genera, Adonis, Myosurus, and Ranunculus. The deter- mination is soon made, upon noting the naked sepals, the petals with the little scale on the upper face of the short claw, and the akenes in a head: so the genus is, 7. RANUNCULUS. 186 HOW TO STUDY PLANTS. [LESSON 30. 536. The arrangement of the species of Ranunculus is to be found, under the proper number, 7, on p. 37 and the following. The first section contains aquatic species ; ours is terrestrial, and in all other particulars answers to § 2. The smooth ovary and akene, and the perennial root refer it to the subsection following, marked by the single star. The shape of the leaves excludes it from the "•*— Spearwort Crowfoots," the large and showy petals from the " •»— H- Small-flowered Crowfoots ; while all the marks agree with H- 4— -t— BUTTERCUPS or COMMON CROWFOOTS. There is still a subdivision, one set marked, " -M- Natives of the country, low or spreading" the other " ++ ++ Introduced weeds from Europe, com- mon in fields, fyc.: stem erect: leaves much cut" — which is the case. We have then only to choose between the two field Crow- foots, and we have supposed the pupil to have in hand the lower, early-flowered one, common at the east, which has a solid bulb or corm at the base of the stem, and displays its golden flowers in spring or earliest summer, and which accordingly answers to the description of RANUNCULUS BULBOSUS, the BULBOUS BUTTERCUP. 537. Later in the season it might have been R. acris, the Tall Buttercup, or much earlier R. fascicularis, or JR. rcpens. Having ascertained the genus from any one species, the student would not fail to recognize it again in any other, at a glance. 538. If now, with the same plant in hand, the Manual (Fifth edition) be the book used, the process of analysis will be so similar, that a brief indication of the steps may suffice. Here the corres- ponding Analytical Key, commencing on p. 21, leads similarly to the first Series, Class, Subclass, and Division ; — to A, with nume- rous stamens; 1, with calyx entirely free and separate from the pistil or pistils, thence to the fourth line beginning with the word Pistils; thence to the third of the three subordinate propositions, viz. to " Stamens inserted on the receptacle " ; to the second of the succeeding couplet, or "Filaments longer than the anther"; to the second of the next couplet, " Flowers perfect," &c., and to the first of the final couplet, " Leaves not peltate ; petals deciduous," — which ends in " RANUNCULACEJE, 34." This is the technical name of the family, and the page where it is described. 539. Turning to that page we read the general description of that order, particularly the portion at the beginning printed in italics, which comprises the more important points. The " Synopsis of the LESSON 31.] HOW TO STUDY PLANTS. 187 Genera " which follows is similar to, but more technical than that of the other, more elementary book ; and the names of the tribes or natural groups of genera (507) are inserted. The steps of analysis bring the student to the Tribe III. RANUNCULEJS, and under it to the genus RANUNCULUS. The number prefixed to the name enables the student to turn forward and find the genus, p. 40. The name, scientific and popular, is here followed by a full generic character (520). The primary sections here have names : the plant under examination belongs to " § 2. RANUNCULUS proper " ; and thence is to be traced, through the subdivisions *, -f— •»— 4- 4- , n-t- +-»-, to the ultimate subdivision &., under which, through a comparison of characters, the student reaches the species R. BULBOSUS, L. 540. The L. at the end of the name is the recognized abbrevia- tion of the name of Linnaeus, the botanist who gave it. Then come the common or English names ; then the specific character ; after this, the station where the plant grows, and the region in which it occurs. This is followed by the time of blossoming (from May to July); and then by some general descriptive remarks. The expression " Nat. from Eu." means that the species is a naturalized emigrant from Europe, and is not original to this country. But all these details are duly explained in the Preface to the Manual, which the student who uses that work will need to study. LESSON XXXI. HOW TO STUDY PLANTS: FURTHER ILLUSTRATIONS. 541. BEGINNERS should not be discouraged by the slow progress ey must needs make in the first trials. By perseverance the vari- ous difficulties will soon be overcome, and each successful analysis will facilitate the next. Not only will a second species of the same genus be known at a glance, but commonly a second genus of the same order will be recognized as a relative at sight, by the family likeness. Or if the family likeness is not detected at the first view, frill be seen as the characters of the plant are studied out. )42. To help on the student by a second example, we will take common cultivated Flax. Turning to the Key, as before, on 188 HOW TO STUDY PLANTS. [LESSON 31. p. 12, the student is led to ask, first, is the plant PELENOGAMOUS or FLOWERING ? Of course it is ; the blossom, with its A stamens and pistils, answers that question. Next, to which of the two classes of Flowering Plants does it belong ? If we judge by the stem, we ask whether it is exogenous or endogenous (422-424). A section of the stem, considerably magnified, given on page 151, we may here repeat (Fig. 362) ; it plainly shows a ring of wood between a central pith and a bark. It is therefore exogenous. Moreover, the leaves are netted-veined, though the veins are not conspicuous. We might even judge from the embryo ; for there is little difficulty in dissecting a flax-seed, and in finding that almost the whole interior is occupied by an embryo with two cotyledons, much like that of an apple-seed (Fig. 11, 12), and this class, as one of its name denotes, is dicotyledonous. If we view the parts of the blossom, we perceive they are five throughout (Fig. 363, 365), a number which occurs in that class only. All these marks, or as many of them as the student is able to verify, show that the plant belongs to Class I. EXOGENOUS or DICOTYLEDONOUS PLANTS. 543. To which subclass, is the next inquiry. The single but several-celled ovary in the centre of the flower, enclosing the ovules, assures us that it belongs to the ANGIOSPERMOUS subclass, p. 13. 544. To get a good idea of the general plan of the flower, before proceeding farther, cut it through the middle lengthwise, as in Fig. 3G4, and also take a slice across a flower-bud, which will bring to view an arrangement somewhat like that of Fig. 365. Evidently the blossom is regularly constructed upon the number five. It has a calyx of five sepals, a corolla of iive petals, live stamens, and five FIG. 332. Section of the stem of Flax, magnified. SJ3. Summit of a branch of the common Flax, with two flowers. 3G4. A llowcr divided lengthwise and enlarged. LESSON 31.] HOW TO STUDY PLANTS. 189 styles, with their ovaries all combined into one compound ovary. We note, also, that the several parts of the blos- som are all free and unconnected, — the leaves of the calyx, the petals, and the stamens all ris- ing separately one after another from the recep- tacle underneath the ovary ; but the filaments, on close inspection, may show a slight union among themselves, at the base. 545. So our plant, having 5 separate petals, is of the POLYPETA- LOUS division of the first class, for the analysis of which see page 14. 546. But it does not belong to the primary division A, which has more than 10 stamens. The student passes on, therefore, to the counterpart division B, on page 16, to which the few stamens, here only five, refer it. 547. Of the three subdivisions, with numerals prefixed, only the second answers ; for the calyx is free from the ovary, and there is only one ovary, although the styles are five. 548. The divisions subordinate to this form a couplet ; and our plant agrees with the second member of it, having " Stamens of the same number as the petals " [5] and " alternate with them." The division under this is a triplet, of which we take the third member ; for the " Leaves are not punctate with pellucid dots." Under this, in turn, is a triplet beginning with the word Ovary, and the five, if not ten cells, determine our choice of the third member of it, " Ovary compound." Under this we have no less than nine choices, dependent upon the structure of the ovary, the number of ovules and seeds, &c. But the 5-celled ovary with a pair of ovules in each cell, separated by a false partition projecting from the back (Fig. 365), so that the pod becomes in fact 10-celled, with a sol- itary seed in each cell, is described only in the ninth and last of the set, p. 18. Under this, again, we have to choose among five propositions relating to the seeds. Here the fifth — " Seeds and ovules only one or two in each cell " — alone meets the case. Under this, finally, we have to choose from six lines, beginning with the words Tree, Shrubs, or Herbs. The fifth alone agrees, and leads to the FLAX FAMILY, p. 77. 549. There is only one genus of it in this country, namely, the FLAX genus itself, or LINUM. To determine the species, look first FIG. 365. Cross-section of an unexpanded flower of the same, a sort of diagram. 190 HOW TO STUDY PLANTS. [LESSON 31. at the three section?, marked with stars. The second answers to our plant ; and the annual root, pointed sepals, and blue petals deter- mine it to be the COMMON FLAX, LINUM USITATISSIMUM. 550. By the Manual, the same plant would be similarly traced, along a somewhat different order of steps, down to the genus on p. 104, and to the species, which being a foreign cultivated one, and only by chance spontaneous, is merely mentioned at the close. 551. After several analyses of this kind, the student will be able to pass rapidly over most of these steps ; should ordinarily recog- nize the class and the division at a glance. Suppose a common Mal- low to be the next subject. Having flowers and seeds, it is Phaeno- gamous. The netted-veined leaves, the structure of the stem, and the leaves of the flower in fives, refer it to Class I. The pistils, of the ordinary sort, refer it to Subclass I. The five petals refer it to the Polypetalous division. Turning to the Key in the Field, Forest, and Garden Botany, and to the analysis of that division, commencing on p. 14, the numerous stamens fix it upon A, under which the very first line, " Stamens monadelphous, united with the base of the corolla; anthers kidney-shaped, one-celled," exactly expresses the structure of these organs in ouu; plant, which is thus determined to be of the MALLOW FAMILY, -^for which see page 70. 552. After reading the character of the family, and noting its agreement in all respects, we fix upon § 1, in which the anthers are all borne at the top, and not down the side of the tube of filaments. We pass the subdivision with a single star, and choose the alternative, with two stars, on account of the ring of ovaries, &c. ; fix upon the division •»-, on account of the stigmas running down one side of the slender style, instead of forming a little head or blunt tip at their apex ; and then have to choose among five genera. The three separate bracts outside of the calyx, the obcordate petals, a"nd the fruit determine the plant to be a MALVA. Then, referring to p. 71 for the species, the small whitHi flowers point to the first division, and a comparison of the characters of the two species under it, assures us that the plant in hand is MALVA ROTUNDIFOLIA. 553. For the sake of an example in the Monopetalous Division, we take a sort of Morning-Glory which is often met with climbing over shrubs along the moist banks of streams. Its netted-veined leaves, the sepals arid the stamens being five, — also the structure of the stem, if we choose to examine it, and the embryo with two leafy LESSON 31.] HOW TO STUDY PLANTS. 191 cotyledons (as in Fig. 26), readily inspected if we have seeds, — show it belongs to Class I. Its pistil refers it of course to Subclass I. The corolla being a short funnel-shaped tube, theoretically regarded as formed of five petals united up to the very summit or border, ren- ders the flower a good illustration of the MONOPETALOUS DIVISION, the analysis of which begins on p. 20, in the work we are using. 554. The calyx free from the ovary excludes it from the section A, and refers it to section B. This is subdivided, in the first place, by the number of the stamens, and their position as respects the lobes of the corolla. Now, as the petals of the corolla in this flower are united up to the very border, the student may at first be puzzled to tell how many lobes it should have, or, in other words, how many petals enter into its composition. But the five leaves of the calyx would lead one to expect a corolla of five parts also. And, although there are here really no lobes or notches to be seen, yet the five plaits of the corolla answer to the notches, and show it to consist of five petals perfectly united. Since the stamens are of the same number as the plaits of the corolla, and are placed before them (as may be best seen by splitting down the corolla on one side and spreading it out flat), it follows that they alternate with the lobes or petals ; therefore our plant falls under the third subdivision : " Sta- mens as many as the lobes or parts of the corolla and alternate with them." This subdivides by the pistils. ^Our plant, having a pistil with two stigmas and two cells to the ovary, must be referred to the fifth and last category : " Pistil one, with a single compound ovary,'* &c. We are then directed to the stamens, which here are " plainly borne on the corolla " ; next to the leaves, which are on the stem (not all at the root), also alternate, without stipules; the stamens 5, and the ovary 2-celled, — all of which accords with the seventh of the succeeding propositions, and with no other. The middle one alone under this agrees as to the ovary and seeds, and all is confirmed by the twining stem. It is the CONVOLVULUS FAMILY, p. 262. 555. The proper Convolvulus Family has green foliage, as has our plant. Its style is single and entire, as in § 1. Its calyx has a pair of large leafy bracts, as in the subdivision with two stars. So we reach the genus CALYSTEGIA, or BptACTED BINDWEED. 556. Under this genus two species are described : the twining stem, and the other particulars of our plant, direct us to the first C. SEPIUM, which in England is named HEDGE BINDWEED, and here is one of the various Convolvulaceous plants known as MORNING-GLORY. 192 HOW TO STUDY PLANTS. [LESSON 32. LESSON XXXII. HOW TO STUDY PLANTS: FURTHER ILLUSTRATIONS. 557. THE foregoing illustrations have all been of the first or Ex- ogenous class. We will take one from the other class, and investi- gate it by the Manual. 558. It shall be a rather common plant of our woods in spring, the Three-leaved Nightshade, or Birthroot. With specimens in hand, and the Manual open at the Analytical Key, p. 21, seeing that the plant is of the Pha3nogamous series, we proceed to deter- mine the class. The netted-veined leaves would seem to refer the plant to the first class; while the blossom (Fig. 366, 367), con- structed on the number three, naturally directs us to the second class, in which this number almost universally prevails. Here the stu- dent will be somewhat puzzled. If the seeds were ripe, they might be examined, to see whether the embryo has one cotyledon only, or a pair. But the seeds are not to be had in spring, and if they were, the embryo would not readily be made out. We must judge, therefore, by the structure of the stem. Is it exogenous or endogenous ? If we cut the stem through, or take off a thin slice crosswise and lengthwise, we shall perceive that the woody matter in it consists of ^; ^^v a number of threads, interspersed throughout / \ the soft cellular part without regularity, and not / /» . — . I collected into a ring or layer. In fact, it is just like the Corn-stalk (Fig. 351), except that the woody threads are fewer. It is therefore endo- genous (422) ; and this decides the question in favor of Class II. MONOCOTYLEDONOUS or EN- DOGENOUS PLANTS (page 30), notwithstanding the branching veins of the loaves. For neither this character, nor the number of parts in FIG. 33G. Flower of Trillium ercctum, viewed from above. 367. Diagram of the same, a cross-section of the unopened blossom, showing the number and arrangement of parts. LESSON 32.] HOW TO STUDY PLANTS. 193 the blossom, holds good universally, while the plan of the stem does. 559. The single flower of our plant with distinct calyx and corolla takes us over the Spudiceous to the PETALOIDEOUS DIVISION: the Petaloideous Division of Endogens there begins on p. 28. These parts being free from and beneath the ovary, refer us to the third subdivision, viz : "3. Perianth ivholly free from the ovary." 559a. The pistil is next to be considered : it accords with the third of the triplet: "Pistil one, compound (cells or placenta 3) ; anthers 2-celled." Under this follows a triplet, of which the initial word is "Perianth": our choice falls upon the first, as there is nothing " glumaceous " about this flower. 560. The succeeding triplet relates to the stamens; here 6, so we take the first alternative. The next refers to mode and place of growth : our plant is " Terrestrial, and not rush-like." The next again to the perianth : the second number of the triplet : " Perianth of 3 foliaceous and green sepals, and 3 colored withering-persistent petals " (as would be seen after flowering-time), brings us to a par- ticular group in the great Lily family, or LILIACE^E, p. 520. 561. Reading over the family character, and collating the five tribes comprised, we perceive that our plant belongs to the group, quite peculiar among Liliaceous plants, here ranked as Tribe I. TRILLIDE^E, the Trillium tribe. And the next step, leading to a choice between two genera, determines the genus to be TRILLIUM. 562. Turning to this, on p. 522, and reading the full description of it, we proceed to the easy task of ascertaining the species. The " flower is raised on a peduncle," as in § 2. This peduncle is slender and nearly erect, and all the other particulars accord with the sub- division marked by a single star. And, finally, the ovate, acutish, widely-spreading, dark dull-purple petals mark the species as the PURPLE BIRTHROOT, TRILLIUM ERECTUM, L. 563. By the Field, Forest, and Garden Botany, the analysis is similar, only more simple. The details need not be particularly recapitulated. 564. The student residing west of New England will also be likely to find another species, with similar foliage, but with larger, pure white, and obovate petals, turning rose-color when about to fade. This will at once be identified as T. grandiflorum. And towards the north, in cold and damp woods or swamps, a smaller 17 194 HOW TO STUDY PLANTS. [LESSON 32. species will be met with, having dull-green and petioled leaves rounded at the base, and rather narrow, wavy, white petals, marked with pink or purple stripes at the base : this the student will refer to T. erythrocarpum. But the species principally found in the east- ern parts of the country has a short peduncle recurved under the leaves, so as nearly to conceal the much less handsome, dull white flower : this, it will be seen, is T. cernuum, the Nodding Trillium or Wake Robin. 565. Whenever the student has fairly studied out one species of a genus, he will be likely to know the others when he sees them. And when plants of another genus of the same order are met with, the order may generally be recognized at a glance, from the family resemblance. For instance, having first become acquainted with the Convolvulus family in the genus Calystegia (555), we recognize it at once in the common Morning- Glory, and in the Cypress-Vine, and even in the Dodder, although these belong to as many different genera. Having examined the common Mallow (552), we immedi- ately recognize the Mallow family (Malvacece) in the Marsh-Mallow, sparingly naturalized along the coast, in the Glade Mallow, and the Indian Mallow, in the Hibiscus or Rose-Mallow, and so of the rest : for the relationship is manifest in their general appearance, and in the whole structure of the flowers, if not of the foliage also. 566. So the study of one plant leads naturally and easily to the knowledge of the whole order or family of plants it belongs to : — which is a great advantage, and a vast saving of labor. For, although we have about one hundred and thirty orders of Flowering Plants represented in our Botany of the Northern States by about 2,540 species, yet half of these species belong to nine or ten of these orders ; and more than four fifths of the species belong to forty of the orders. One or two hundred species, therefore, well examined, might give a good general idea of our whole botany. And students who will patiently and thoroughly study out twenty or thirty well- chosen examples will afterwards experience little difficulty in determin- ing any of our Flowering Plants and Ferns,.and will find the pleasure of the pursuit largely to increase with their increasing knowledge. 567. And the interest will be greatly enhanced as the student, rising to higher and wider views, begins to discern the System of Botany, or, in other words, comprehends more and more of the Plan of the Creator in the Vegetable Kingdom. LESSON 33.] NATURAL SYSTEM. 195 LESSON XXXIII. BOTANICAL SYSTEMS. 568. Natural System. The System of Botany consists of the orders or families, duly arranged under their classes, and having the tribes, the genera, and the species arranged in them according to their re- lationships. This, when properly carried out, is the Natural System ; because it is intended to express, as well as we are able, the various degrees of relationship among plants, as presented in nature ; — to rank those species, those genera, &c. next to each other in the classi- fication which are really most alike in all respects, or, in other words, which are constructed most nearly on the same particular plan. 569. Now this word plan of course supposes a planner, — an in- telligent mind working according to a system : it is this system, therefore, which the botanist is endeavoring as far as he can to exhibit in a classification. In it we humbly attempt to learn some- thing of the plan of the Creator in this department of Nature. 570. So there can be only one natural system of Botany, if by the term we mean the plan according to which the vegetable creation was called into being, with all its grades and diversities among the species, as well of past as of the present time. But there may be many natural systems, if we mean the attempts of men to interpret and express the plan of the vegetable creation, — systems which will vary with our advancing knowledge, and with the judgment and skill of different botanists, — and which must all be very imperfect. They will all bear the impress of individual minds, and be shaped by the current philosophy of the age. But the endeavor always is to make the classification a reflection of Nature, as far as any system can be which has to be expressed in a series of definite propositions, and have its divisions and subdivisions following each other in some single fixed order.* * The best classification must fail to give more than an imperfect and con- siderably distorted reflection, not merely of the plan of creation, but even of our knowledge of it. It is often obliged to make arbitrary divisions where Nature shows only transitions, and to consider genera, &c. as equal units, or groups of equally related species, while in fact they may be very unequal, — to assume, on 196 BOTANICAL SYSTEMS. [LESSON 33. 571. The Natural System, as we receive it, and as to that portion of it which is represented in the botany of our country, is laid before the student in the Manual of the Botany of the Northern United States. The orders, however, still require to be grouped, according to their natural relationships, into a considerable number of great groups (or alliances) ; but this cannot yet be done throughout in any easy way. So we have merely arranged them somewhat after a custom- ary order, and have given, in the Artificial Key, a contrivance for enabling the student easily to find the natural order of any plant This is a sort of 572. Artificial Classification, The object of an artificial classifica- tion is merely to furnish a convenient method of finding out the name and place of a plant. It makes no attempt at arranging plants ac- cording to their relationships, but serves as a kind of dictionary. It distributes plants according to some one peculiarity or set of pecu- liarities (just as a dictionary distributes words according to their first letters), disregarding all other considerations. 573. At present we need an artificial classification in Botany only as a Key to the Natural Orders, — as an aid in referring an unknown plant to its proper family ; and for this it is very needful to the student. Formerly, when the orders themselves were not clearly made out, an artificial classification was required to lead the student down to the genus. Two such classifications were long in vogue. First, that of Tournefort, founded mainly on the leaves of the flower, the calyx and corolla : this was the prevalent system throughout the first half of the eighteenth century ; but it has long since gone by. It was succeeded by the well-known artificial system of Linnaeus, which has been used until lately ; and which it is still worth while to give some account of. 574. The Artificial System Of LinnffiUS was founded on the stamens and pistils. It consists of twenty-four classes, and of a variable number of orders, which were to take the place temporarily of the natural classes and orders ; the genera being the same under all classifications. paper at least, a strictly definite limitation of genera, of tribes, and of orders, although observation shows so much blending here and there of natural groups, sufficiently distinct on the whole, as to warrant us in assuming the likelihood that the Creator's plan is one of gradation, not of definite limitation, even perhapi to the species themselves. LESSON 33.] ARTIFICIAL SYSTEM OF LINNJEUS. 197 575. The twenty-four classes of Lirmasus were founded upon something about the stamens. The following is an analysis of them. The first great division is into two great series, the Phce- nogamous and the Cryptogamous, the same as in the Natural System. The first of these is divided into those flowers which have the sta- mens in the same flower with the pistils, and those which have not; and these again are subdivided, as is shown in the following tabular view.

The names of these classes are all compounded of Greek words. The first eleven consist of the Greek numerals, in succes- sion, from 1 to 11, combined with andria, which here denotes sta- mens ; — e. g. Monandria, with one stamen; and so on. The llth has the numeral for twelve stamens, although it includes all which have from eleven to nineteen stamens, numbers which rarely occur. The 12th means " with twenty stamens," but takes in any higher number, although only when the stamens are borne on the calyx. The 13th means " with many stamens," but it takes only those with the stamens borne on the receptacle. The 14th means "two stamens powerful," the shorter pair being supposed to be weaker ; the 15th, "four powerful," for the same reason. The names of the next three classes are compounded of adelphia, brotherhood, and the Greek words for one, two, and many (Monadelphia, Diadelphia, and Poly adelphia). The 19th means "united in one household." The 20th is compounded of the words for stamens and pistils united. The 21st and 22d are composed of the word meaning house and the numerals one, or single, and two : Moncecia, in one house, Dicecia, in two houses. The 23d is fancifully formed of the words meaning plurality and marriage, from which the English word polygamy is derived. The 24th is from two words meaning concealed nuptials, and is opposed to all the rest, which are called Phcenogamous, be- cause their stamens and pistils, or parts of fructification, are evident. 577. Having established the classes of his system on the stamens, Linnaeus proceeded to divide them into orders by marks taken from the pistils, for those of the first thirteen classes. These orders de- pend on the number of the pistils, or rather on the number of styles, or of stigmas when there are no styles, and they are named, like the classes, by Greek numerals, prefixed to gynia, which means pistil Thus, flowers of these thirteen classes with One style or sessile stigma belong to Order 1.

The orders of the remaining classes are founded on various considerations, some on the nature of the fruit, others on the number and position of the stamens. But there is no need to enumerate them here, nor farther to illustrate the Linnaean Artificial Classifi- cation. For as a system it has gone entirely out of use ; and as a Key to the Natural Orders it is not so convenient, nor by any means so certain, as a proper Artificial Key, prepared for the purpose, such as we have been using in the preceding Lessons. LESSON XXXIV. HOW TO COLLECT SPECIMENS AND MAKE AN HERBARIUM. 579. For Collecting Specimens the needful things are a large knife, gtrong enough to be used for digging up bulbs, small rootstocks, and the like, as well as for cutting woody branches ; and a botanical box, or a portfolio, for holding specimens which are to be carried to any distance. 580. It is well to have both. The botanical box is most useful for holding specimens which are to be examined fresh. It is made of tin, in shape like a candle-box, only flatter, or the smaller sizes like an English sandwich-case ; the lid opening for nearly the whole length of one side of the box. Any portable tin box of con- lient size, and capable of holding specimens a foot or fifteen inches ig, will answer the purpose. The box should shut close, so that specimens may not wilt : then it will keep leafy branches and most flowers perfectly fresh for a day or two, especially if slightly moistened. 581. The portfolio should be a pretty strong one, from a foot to twenty inches long, and from nine to eleven inches wide, and fasten- ing with tape, or (which is better) by a leathern strap and buckle at the side. It should contain a quantity of sheets of thin and smooth, unsized paper ; the poorest printing-paper and grocers' tea-paper are very good for the purpose. The specimens as soon as gathered are to be separately laid in a folded sheet, and kept under moderate pressure in the closed portfolio. 200 HOW TO PRESERVE SPECIMENS, [LESSON 34. 582. Botanical specimens should be either in flower or in fruit. In the case of herbs, the same specimen will often exhibit the two ; and both should by all means be secured whenever it is possible. Of small herbs, especially annuals, the whole plant, root and all, should be taken for a specimen. Of larger ones branches will suf- fice, with some of the leaves from near the root. Enough of the root or subterranean part of the plant should be collected to show whether the plant is an annual, biennial, or perennial. Thick roots, bulbs, tubers, or branches of specimens intended to be preserved, should be thinned with a knife, or cut into slices lengthwise. 583. For drying Specimens a good supply of soft and unsized paper — the more bibulous the better — is wanted ; and some convenient means of applying pressure. All that is requisite to make good dried botanical specimens is, to dry them as rapidly as possible between many thicknesses of paper to absorb their moisture, under as much pressure as can be given without crushing the more delicate parts. This pressure may be given by a botanical press, of which various forms have been contrived ; or by weights placed upon a board, — from forty to eighty or a hundred pounds, according to the quantity of specimens drying at the time. For use while travelling, a good portable press may be made of thick binders' boards for the sides, holding the drying paper, and the pressure may be applied by a cord, or, much better, by strong straps with buckles. 584. For drying paper, the softer and smoother sorts of cheap wrapping-paper answer very well. This paper may be made up into driers, each of a dozen sheets or less, according to the thickness, lightly stitched together. Specimens to be dried should be put into the press as soon as possible after gathering. If collected in a port- folio, the more delicate plants should not be disturbed, but the sheets that hold them should one by one be transferred from the portfolio to the press. Specimens brought home in the botanical box must be laid in a folded sheet of the same thin, smooth, and soft paper used in the portfolio ; and these sheets are to hold the plants until they are dry. They are to be at once laid in between the driers, and the whole put under pressure. Every day (or at first even twice a day would be well) the specimens, left undisturbed in their sheets, are to be shifted into well-dried fresh driers, and the pressure renewed, while the moist sheets are spread out to dry, that they may take their turn again at the next shifting. This course must be continued until the specimens are no longer moist to the touch, — LESSON 34.] AND FORM AN HERBARIUM. 201 which for most plants requires about a week ; then they may be transferred to the sheets of paper in which they are to be preserved. If a great abundance of drying-paper is used, it is not necessary to change the sheets every day, after the first day or two. 585. Herbarium, The botanist's collection of dried specimens, ticketed with their names, place, and time of collection, and sys- tematically arranged under their genera, orders, &c., forms a Hor- tus Slccus or Herbarium. It comprises not only the specimens which the proprietor has himself collected, but those which he ac- quires through friendly exchanges with distant botanists, or in other ways. The specimens of an herbarium may be kept in folded sheets of neat, and rather thick, white paper ; or they may be fastened on half-sheets of such paper, either by slips of gummed paper, or by glue applied to the specimens themselves. Each sheet should be appropriated to one species ; two or more different plants should never be attached to the same sheet. The generic and specific name of the plant should be added to the lower right-hand corner, either written on the sheet, or on a ticket pasted down at that corner ; and the time of collection, the locality, the color of the flowers, and any other information which the specimens themselves do not afford, should be duly recorded upon the sheet or the ticket. The sheets of the herbarium should all be of exactly the same dimensions. The herbarium of Linnceus is on paper of the common foolscap size, about eleven inches long and seven wide. But this is too small for an herbarium of any magnitude. Sixteen and a half inches by ten and a half, or eleven and a half inches, is an approved size. 586. The sheets containing the species of each genus are to be placed in genus-covers, made of a full sheet of thick, colored paper (such as the strongest Manilla-hemp paper), which fold to the same dimensions as the species-sheet ; and the name of the genus is to be written on one of the lower corners. These are to be arranged under the orders to which they belong, and the whole kept in closed cases or cabinets, either laid flat in compartments, like large "pigeon- holes," or else placed in thick portfolios, arranged like folio volumes, and having the names of the orders lettered on the back.

THE additions and alterations of the Revised Edition of this work, now issued, are mainly the following. k The addition of an entirely new part, entitled GARDEN BOTANY, AN INTRODUCTION TO A KNOWLEDGE OF THE COMMON CULTIVATED PLANTS : see pp. xxix. - Ixxxix.' By this, the common exotics, no less than the wild plants, are made available for botanical classes, which will be a great convenience in many cases. Most of these cultivated plants are everywhere common, and generally at hand for botanical illustration ; and it is desirable that they should be scientifically known and rightly named. And there is no great difficulty in studying them, if double flow- ers, and those which are otherwise in a monstrous or unnatural condition, be avoided, at least by beginners. It is obviously absurd and highly in- convenient to mix in the cultivated with the wild plants in such a work as this. But a separate account of the common exotics, annexed and sub- sidiary to the Botany of the Northern United States, especially in the School Edition, will doubtless be popular and useful. Directions for the use of the Garden Botany will be found on p. xvii. and p. xxix. 2. The ANALYTICAL KEY, p. xvii., upon which the pupil so greatly depends, has been altogether revised, much simplified, adapted to the Garden Botany as well as to the Botany of the Northern States, and printed in a larger type. 3. Numerous corrections in particulars have been made throughout the body of the work, whenever the required alterations could well be effected upon the stereotype plates. Many others, suggested by acute and obliging correspondents, or by my own observation, are necessarily deferred until the work can be recomposed. 4. The plants which have been newly detected within our limits, and one or two which were before accidentally omitted, are enumerated and characterized in the ADDENDA, p. xc. 5. Eight plates have been added, crowded with figures, illustrating all the genera (66 in number) of Grasses. They are wholly original, having been drawn from nature and engraved by Mr. Sprague. They will be of great assistance in the study of this large, difficult, and important family. The flattering success which the Manual has met with stimulates the author's endeavors towards its continued improvement; — in regard to which he still solicits aid from his correspondents. HARVARD UNITMSITT, CAMBRIDGE, March 10, 186a PREFACE. THIS work is designed as a compendious Flora of the .Northern portion of the United States, arranged according to the Natural System, for the use of students and of practical botanists. The first edition was hastily prepared to supply a pressing want. Its plan, having been generally approved, has not been altered, although the work has been to a great extent rewritten. Its increased size is mainly owing to the larger geographical area embraced in it, being here extended southward so as to include Virginia and Kentucky, and westward to the Mississippi River. This southern boundary coincides better than any other geographical line with the natural division between the cooler-temperate and the warm- temperate vegetation of the United States; very few characteristically Southern plants occurring north of it, and those only on the low coast of Virginia, in the Dismal Swamp, &c. Our western limit, also, while it includes a considerable prairie vegetation, excludes nearly all the plants peculiar to the great Western woodless plains, which approach our borders in Iowa and Missouri. Our northern boundary, being that of the United States, varies through about five degrees of latitude, and nearly embraces Canada proper on the east and on the west, so thaf nearly all the plants of Canada East on this side of the St. Lawrence, as well as of the deep peninsula of Canada West, will be found described in this volume. The principal facts respecting the geographical distribution of the plants which compose the flora of our district, will be presented in another place. In this work I endeavor briefly to indicate the district in which each species occurs, or in which it most abounds, in the following manner : 1. When the principal area of a species is northward rather than south- ward, I generally give first its northern limit, so far as known to me, if within the United States, and then its southern limit if within our boun- daries, or add that it extends southicard, meaning thereby that the species Vlll PREFACE. in question occurs in the States south of Virginia or Kentucky. Thus Magnolia glauca, p. 16, a prevailingly Southern species, but which is spar- ingly found as far north as Massachusetts, is recorded as growing " near Cape Ann and New York southward, near the coast"; M. acuminata, " W. New York, Pennsylvania, Ohio, and southward " ; &c. While in species of northern range, the southern limits are mentioned; as, Nupkar Kalmiana, p. 23, "New England, New York, and northward"; Cardamine pratentsist p. 33, " Vermont to Wisconsin, northward," &c. And so of Western plants; e.g. hopyrum biternatum, p. 11, "Ohio, Kentucky, and westward " ; Psoralea arynphylla, p. 94, " Wisconsin and westward " ; Amorpha canesccns, p. 95, " Michigan to Wisconsin, and southwestward." 2. "Where no habitat or range is mentioned, the species is supposed to be diffused over our whole area, or nearly so, and usually beyond it. 3. When the species is of local or restricted occurrence, so far as known, the special habitat is given ; e. g. Vesicaria Shortii and V. Lescurii, p. 38 ; Suttivantia Ohionvt, p. 144, &c. Except in such cases, the want of space has generally demanded the omission of particular localities, which are so appropriate and so useful both in local Floras and in more detailed works, but for which there is no room in a manual like this. For the same reason, I could not here undertake to specify the range ol those species which extend beyond the geographical limits of this work, or beyond the United States. Nevertheless, to facilitate the comparison of our flora with that of Europe, I have appended the mark (Eu.) to those species which are indigenous to both. Foreign plants which have become denizens of the soil are of course enu- merated and described along with the genuine indigenous members of our flora; but the introduced species are distinguished by the specific name be- ing printed in a different type, namely, in small capitals (e. g. Ranunculus ACKIS, p. 10), while the names of the indigenous species are in full-face letter (e. g. IS. repciis). Moreover, the country from which they were introduced is specified (mostly Europe), as well as the nature of the dcni- zenship. That is, foUoAving the suggestions of M. Alphonse De Candolle, I have classified our introduced plants as well as I could into two sorts, the thoroughly naturalized, and the advcntive ; the first comprising those species which have made themselves perfectly at home in this country, propagating themselves freely by seed beyond the limits of cultivated grounds ; the sec- ond, those which are only locally spontaneous, and perhaps precarious, 01 which are spontaneous only in cultivated fields, around dwellings, or in manured soil, and which, still dependent upon civilized man, would prob- ably soon disappear if he were to abandon the country. (I here rank with the adccnticc plants those which De Candolle terms plants cultivate;! with out or against man's will.) Accordingly the species naturalized from Europ. are indicated, at the close of the paragraph, by the phrase " (Nat. froue PREFACE. 1X Eu.) " . those adventire, or imperfectly naturalized from Europe, by the phrase " (Adv. from Eu.)," &c. Such varieties as are marked and definite enough to require names are distinguished in this edition into two sorts, according to their degree of ap- parent distinctness: — 1. Those which, I thiuk, can hardly be doubted to be varieties of the species they are referred to, at least by those who hold sound views as to what a species is, have the name printed in small capi- tals; e.g. Nasturtium palustre, var. HISPIDUM, p. 30 ; Vitis cordifolia, var. RIPARIA, p. 78. '2. Those so peculiar that they have not only for the most part been taken for species, but may still be so regarded by many most excellent botanists ; some of them I may myself so regard hereafter, on further and more critical examination of the apparently connecting forms. The names of these are printed in the same full-face type as those of the indigenous species (e. g. Ranunculus aquatilis, var. divai'icatiis, p. 7; Actaea spicata, var. r&ibra, and var. alba, p. 14) ; and they usu- ally stand at the head of a separate paragraph. Another important feature of the present edition consists in the plates, fourteen in number, crowded with figures, illustrating the genera of the six Cryptogamous Orders (Mosses, Ferns, &c.) embraced in the work. The eight most elaborate and admirable plates illustrating the Mosses and Liv- erworts are furnished by my generous friend, MR. SULLIVANT, the author of that portion of this work.* The remaining six plates, devoted to the Ferns and their allies, were drawn from nature, and executed by MR,. ISAAC SPRAGUE. MR. SULLIVANT has included in this edition all the species of Musci and flepaticce known to him as natives of any part of ffie United States east of the Mississippi, and has sedulously elaborated the whole anew ; not only laying a broad foundation for a knowledge of North American Muscology, but furnishing botanical students with facilities for the study of these two beautiful families of plants such as have never before anywhere been afforded in a book of this kind, j * The illustrations of forty of the genera, as indicated in the Explanation of the Plates at the close of the volume, are entirely original productions of Mr. Sullivant's pencil. Seven of them represent new species, and for most of the others those species were chosen which have before been only imperfectly if at all figured. The rest of the genera were taken from Schim- per, Bischoff, or Hooker, but amended or altered in accordance with the object in view, and the suggestions of an actual examination of the plant, which was always made. t The reference " Muse. Bor.-Amer.," appended to many new or rare Mosses, is made to an almost complete arranged collection of the Musci and Hepatir.cp, east of the Mississippi, the types in great measure of the present elaboration of these families, all critically studied b/ Messrs. Fullivant and Lesquereux, and published in sets of specimens by the latter. The materials from which these s«ts have been prepared are chiefly Mr. Lesquereux's own very extensive collections, the rosult of his numerous journeys made during the last six or seven years, especially in the southern ranges of the Alleghany Mountains. To these have been a'lde-1 Mr. SuLlivuut's ample accumulations, embracing :iio collections of the lamented X PREFACE. Probably the time is now not far distant when, as the result especially of the labors anl investigations of PROF. TUCKERMAN upon our Licheneat of the REV. DR. CURTIS upon our Funyi, and of PROF. HARVEY upon our Alyfc, as well as of Messrs. SULLIVANT and LESQUEREUX upon our Mosses, all our Cryptogamia may be in a similar manner presented to tho student, in the form of a supplementary volume, separate from that com- prising the Phaenogamous or Flowering Plants. T have omitted from this edition the concise Introduction to Botany, and the Glossary, prefixed to the first; supplying their place with a more extended, familiar, and copiously illustrated elementary work, especially intended for beginners {First Lessons in Botany), and which may, when desired, be bound up with the present volume. Or the student may use the author's Botanical Text-Book for the same purpose. In either of these, all the technical terms employed in this volume are explained and illus- trated. Having prepared this Manual for students rather than for learned botanists, I have throughout endeavored to smooth the beginner's way by discarding many an unnecessary technical word or phrase, and by casting the language somewhat in a vernacular mould, — perhaps at some sacrifice of brevity, but not, I trust, of the precision for which botanical language is distinguished. Botanists may find some reason to complain of the general omission of synonymes ; but it should be considered that all synonymes are useless to the beginner, — whose interests T have particularly kept in view, — while the greater part are needless to the instructed botanist, who has access to more elaborate works in which they are plentifully given. By discarding them, except in case of some original or recent changes in nomenclature, 1 have been able to avoid abbreviations (excepting those of author's names, and some few customary ones of States, &c.), to give greater fulness to the characters of the species, and especially of the genera, (a point in which I conceive most works of this class are deficient,) and also to add the deriva- tion of the generic names. The Natural Orders are disposed in a series which nearly corresponds, in a general way, with De Candolle's arrangement, beginning with the highest class and ending with the lowest; and commencing this first and far the largest class (of Dicotyledonous or Exogenous Plants) with those orders in which the flowers are mostly provided with double floral enve- Mr. Oakes in the \Vhite Mountains, of Fendler in New Mexico, and of Wright in Texas The title of the work ia " Musci Boreali-Auiericani, sire Specimina Exsiccate Muscorun in Ameri- cae Kebuspublicis Foederatis detcctoruin, conjunctis studiis \V. S. SULLIVANT et L. LESQCERECX, 1856." Mr. Sullivunt's connection with the work extends no further than to a joint and equal ri^|'«i)sibility in the determination of the species. This most extensive and valuable collec- tion ever niale of American Mosses, which has cost much labor and expense, and comprised nearly 400 species and umrked varieties, is published at £20 for each §«t and > ««*gerly nought after by Bryologioal students. PREFACE. XI lopes, viz. with both calyx and corolla, and in which the corolla consists of separate petals (the Polypetalous division) ; beginning this series with those orders in which the several organs of the flower are most distinct and separate (hypogynous), and proceeding to those which have the parts most combined among themselves and consolidated with each other (periyynous and epigynous) ; then follow those with the petals combined into a mono- petalous corolla (the Monopetalous division) ; and, finally, those destitute of a corolla or destitute of all floral envelopes (the Apetalous division). The class of Monocotyledonous or Endogenous Plants opens with orders exhibit- ing one form of simplified flowers, passes to those with the organs most combined and consolidated, then to those most perfect and less combined, and closes with other simplified and reduced forms. The present problem in Botany is to group the numerous Natural Orders in each class into nat- ural alliances. But this has not yet been done in such a manner as to be available to the ordinary student. I do not here attempt, therefore, to group the orders naturally, but let them follow one another in what seems to be on the whole the most natu- ral and practically convenient sequence. And, by means of an Analytical Artificial Key to the Natural Orders* (p. xvii.), I enable the student very readily to refer any of our plants to its proper Family. This Key is entirely remodelled in the present edition, is founded on characters of easy observation, and is so arranged as to provide for all the exceptional instances and variant cases I could think of. I shall be disappointed if the attentive student is not able by it to refer to its proper order any to him unknown plant of the Northern States of which he has flowering speci- mens. Referring to the Order indicated, the student will find its dis- tinctive points, which he has chiefly to consider, brought together and printed in italics in the first sentence of the description. Then, to abridge the labor of further analysis as much as possible, 1 have given a synopsis of the genera under each order, whenever it com prises three or more of them, enumerating some of their leading characters, and grouping them under their respective tribes, suborders, &c., as the case may be. I have also taken pains to dispose the species of every ex- tensive genus under sections (§) or subgenera (§ with a name in capitals), subsections ( * ), and subordinate divisions (•*-, ++, &c.) ; and whenevf/r there are two or more species under a division, I have italicized some of the principal distinctions (after the manner of Koch's Flora Germanica), BO that they may at once catch the student's eye. To aid in the pronunciation of the generic and specific names, &c., 1 * No Linnsean Artificial Arrangement Is here given, experience having shown that, as a Kej to the Natural Orders or to the genera, it offers no clear advantage on the score of facility ovei a well-devised Analytical Key ; which the learner will find equally certain, and much uw>n. satisfactory in its results. Xli PREFACE. ha\ e not only marked the accented syllable, but have followed London's mode of indicating what is called the long sound of the vowel by the grave (v), and the short sound by the acute accent-mark ('). In respect to this, my friend, MR. FOLSOM, has obligingly rendered most important assistance throughout the pages of this volume. The imperative necessity of economizing space to the utmost, alone has debarred me from more largely recording my acknowledgments to nu- merous obliging correspondents, in all parts of the country, who have con- tributed to this work, either by notes of corrections, observations, or cata- logues, or by communicating specimens of rare or local plants. In the comparison of our ilora with that of Europe, I am greatly indebted to my excellent friend and correspondent, M. GODET of Neuchatel, author of the Flare du Jura, for a suite of authentically determined plants of that district, and for a series of acute and very important critical notes upon many of our own identical or related species. As to special collaborators in the preparation of the work, in addition to tlie acknowledgments made in the preface to the former edition, I have again to express my particular indebtedness to my friends, JOHN CAREY, ESQ., now cf London, for various emendations in the genus Carex, formerly elaborated by him for this work ; and DR. ENGELMANN of St. Louis, for full notes upon the botany of our Western borders, many critical obser- vations upon various genera, and for contributing the articles upon Cus- cuta, Euphorbia, and the three genera of Alismece. The renewed and still more extensive contributions of MR. SULLIVANT have already been referred to, — contributions which introduce a new era in the study of American Muscology, and which justly claim, not only my warm per- Eonal acknowledgments, but the gratitude of all the votaries of our science in this country. I renew the request, that those who use this book will kindly furnish information of all corrections or additions that may appear to be necessary, to that it may be made more accurate and complete in a future edition.

THE Student is supposed to have a general acquaintance with the rudiments of Structural Botany, such as is readily to be acquired from the author's First Lessons in Botany, or his Botanical Text-Book, or from any other similar trea- tise. One of these will be needed for reference while using this Manual. The former is much the simplest, and was expressly prepared for the beginner's use To learn the meaning of all words he meets with, and which he does not precise ly understand, he has only to refer, as occasion requires, to the Glossary or Dic- tionary of Botanical Terms appended to either of these books, especially to that in the Lessons on Botany. To show the beginner how to proceed in using the Manual for the purpose of ascertaining the name, and the place in the system, &c. of any of our wild plants, we will f,ake an example. Suppose him to make his first trial with the common Spidcrwort, which grows wild throughout the southern and western parts of our country, is cultivated in most gardens, and blooms the whole summer long. With a flowering specimen in hand, let the student turn to the following Arti- ficial Key to the Natural Orders, p. xvii. Having flowers, it is evident the plant belongs to the great series of Phtenogamous or Flowering Plants. To which of its two classes is the first question. To answer this, let the student compare the plant with the characters — that is, the enumeration of the principal distinc- tions— of Class I. given on p. xviii., and of Class II. on p. xxviii.b Without the seeds, which may not be ripe, — and if they were it might require more skill than could be expected of the beginner to dissect them, — we cannot directly ascertain whether the embryo is monocotylcdonous or dicotyledonous. But the other characters are abundantly sufficient, and easy to verify. Take first the stem ; is it formed on the exogenous or endogenous plan ? A slice across i« linly shows, to the naked eye, or by the aid of a common magnifying-glass, it .here is no distinction of parts into pith, bark, and a ring of wood or woody sue between these two : but the woody part of the stem is here represented by jparate bundles, or threads, whose cut ends, as seen in the cross-section in the rm of dots, are scattered throughout the whole diameter, — just as in a stalk >f Indian Corn, a rattan, or a Palm-stem, — leaving no central pith and showing no tendency to form a ring or layer of wood. It is therefore endogenous. The simple, parallel-veined leaves show the same thing, and so does the arrangement of the flower with its parts in threes, — namely, three sepals, three petals, six (twice 3) stamens ; and even the pistil, if the ovary be cut across, is found to have three cells. So the plant plainly belongs to Class II. Monocotyledonous or Endogenous Plants. We have next to refer it to its proper Order under this Class, which is readily done by following the successive subdivisions in the Artificial Key. The firs! XVI DIRECTIONS TO THE UNPRACTISED STUDENT. division is into three groups, marked A. B. and C. Our plant, having dis- tinct floral envelopes and neither spadix nor glumes, must belong to B., the PetaloiJeous Division. This is subdivided into three sections, designated by stars. The parts of the flower being all separate from each other, our plant evidently falls under the third section, with three stars, viz: "*** Perianth wholly free from the ovary (inferior)." Next, as its perianth consists of three green sepals and three colored petals, it belongs to the subdivision -i — *-. Under this there arc four alternatives, based on differences in the pistil. The numerous distinct pistils exclude the first , the many or several seeds iu each cell exclude the second ; the one-celled ovary, &c., exclude the fourth ; while the third, having a single pistil with a 2-3-celled ovary, and only one or two ovules or seeds in each cell, agrees with our plant ; Avhich we are thus brought to conclude must belong to the order Commelynacece. The number, 485, affixed to this name, refers to the page iu the body of the work where this order is characterized. After comparing the plant with the ordinal character, especially with that por- tion of it in italic type, and noting the agreement, let the student proceed to de- termine the Genus. We have only two genera in this order, viz. : 1. Commelyna, which has irregular flowers, petals unlike and on long claws, and the stamens Df two sorts, only three of them hearing perfect anthers, — all of which is very different from the plant we arc studying; and 2. Tradescantia (p. 486), with the characters of which our plant will be found perfectly to accord. Let the student then proceed to ascertain the Species, of which three are de- scribed under this genus. Of the two sections, marked with stars ( # ), our plant belongs to the first, having a sessile umbel. And of its two species, a comparison with the characters nf each fixes our plant as belonging to the first, viz. T. Viiyinica. The abbreviated name or letter after the name of the genus and that of the species, denotes the founder of the genus or the species ; — in this instance Lin- naeus, whose name is indicated by the abbreviation L. Whenever an order comprises several genera, a synopsis of them is given, like that of Ranuncplaceoe, p. 2, by the aid of which the student will readily deter- mine the genus of the plant under examination. The number prefixed to tbs name of the genus, in the synopsis, is that under which it stands, farther on, in the full account. The genera in the synopsis are often ranked under their proper Tribes, or Suborders, &c. ; and the student will first determine the Tribe, o? other great group to which the plant he is examining belongs, and then the Genus under that tribe, &e. Sometimes a genus embraces two or more strongly marked sections, or Sub- gerura, which arc designated by the mark § followed by a name. For example, CiniicifiKja, p. 14, has two subgcnera, § 1. Mucrc-li/s, and i 2. Ciiin'cifui/a proper, each with its own characters; and the genus films, p. 7G, has three subgcnera, viz. § 1. Snmac, $ 2. Toxioodendron, and $ 3. Lobadimn. These names, how- ever, do not make a part of the appellation of a plant, which is called by its generic and its specific name only; as. Cimicifuga rdcttnosa , the IS/ack Snake- root ; Ithus y/db"1, the Smooth Sumac, &c. ANALYTICAL KEY TO THE NATURAL ORDERS, ftc. OF ALL THE PLANTS DESCRIBED IN THIS WORK. BOTH INDIGENOUS AND EXOTIC. THIS Artificial Analytical Key is a contrivance to lead the pupil, with a plant in his hand to him unknown, Dy a succession of easy steps, up to the name of the natural order to which the plant under examination belongs. The name at the end of the line, to which the student is brought, is that of the natural order sought, for example : MAGNOLTACE^E. The numbers prefixed to the name indicate the page upon which the order is described or treated of, for example: 15 (31) MAGNOLIACE-E. The numbers without parentheses refer to the body of the volume, the indige- nous Botany of the Northern States. Those within parentheses refer to the Garden Botany, which is paged in continuation of the Key. If the plant under examination should be a wild one, the first or unenclosed number is alone to be regarded, and the pupil will turn to that page in the body of the volume. But if an exotic, or a plant here known only in cultivation, the pupil, after reading over the description of the order in the body of the work, as before, (for this description of course is not repeated,) will turn to the page in the Garden Botany indicated by the number enclosed in parentheses. If the only reference is to the Botany of the Northern States, follow that ; for many plants In cultivation are also among our wild plants. Although this Key is a purely artificial contrivance, it is a very necessary one to beginners ; who, however, will very soon get to know the Classes, Sub- classes, &c. at sight, and, after considerable practice, will by degrees be able to recognize at a glance all the commonest natural orders in almost any examples of them they take in hand. The Key is based on the easiest and most obvious botanical characteristics that can be made to answer the purpose ; yet it will bring out, one by one, the principal points, especially in the structure of the flower, by whijh plants are classified and the natural orders distinguished. 2 ANALYTICAL KEY.

THIS simple Introduction to a knowledge of the plants commonly cultivated in tliis country, whether for use or ornament, is prepared as a useful accom paniment to the Botany of the Northern United States, and is made as extensive as the needful limits of such a volume will allow. It will serve the purpose of enabling pupils to study our ordinary exotic as well as indigenous plants, to ascertain their names, and to refer them to their place in the system. It is to be used wholly in connection with the foregoing Artificial Key, p. xv., which is arranged to lead the pupil, if he has an exotic or other cultivated plant in hand, to this Garden Botany, — if a wild plant, to its order in the proper Botany of the Northern. United States. If the cultivated plant be one which ia described in the main body of the work, — as may frequently be the case, — the analysis will conduct to a reference, " Man. p. . . ," where the plant in ques- tion may be found described. It is needless to repeat the description of such species. For the same reason, the character or brief description of the orders and of the genera already in the Botany of the Northern United States is not repeated in the Garden Botany; but a reference, "Manual," or "Man.," followed by the page, directs the student to the place where the order or the genus, &c. is characterized. Since by far the greater part of the names of the genera, &c. of our cultivated plants occur in the body of the work, where they are duly accentuated to in- dicate their proper pronunciation, the accents are not introduced here, except the case of a few words, for the most part not already in the Manual, which particularly liable to be mispronounced. As this Garden Botany is intended to be used only for exercise in botanical analysis, an Index of the names of the plants contained in it, for obvious rea- sons, is purposely omitted.

Larix Europsea, EUROPEAN LARCH, is the species commonly planted, a finer tree and of more rapid growth than the American, its leaves longer, and its cones larger, 1^' long. 4. Thuja orientalis, ORIENTAL ARBOR- VIT^E, is less hardy than ours ; leaves furrowed down the middle ;* cones roundish, the seeds crustaceous and wingless, wherefore it has been separated as a genus, Biota. 5.

B, Salisburia adiantifolia, GINKGO-TREE, of Japan, though htudy, rarely flowers and does not fruit here. It is of the Yew Family, but of most remarkable foliage, the leaves being wedge-shaped or fan-shaped, on a slender petiole, with parallel simply forked veins in the manner of a Fern, the end or margin erosely toothed or cleft. Cedrus, CEDAR, i. e. True Cedar (what are. popularly called Cedars in this country are Junipers, Cypresses, Arbor-Vitae, &c.) is botanicnlly between Larch and Pine, but nearer the former, from which it mainly differs in the leaves being evergreen, therefore more rigid, and pungent, and the cones large, short, and thick, with br^ad and thin scales, closely packed.

The sterile plant is Acnida rusocarpa, MichK., or was mixed with it in Michaux's collection, but not the fertile ; for the fruit of the present plant is neither obtuse- angled, rugose, nor indehiscent.

It was afterwards published by his son, under the name of P. Hudsdnica : he, however, found it " only on the banks of the Hudson River, above Albany." Lastly, it was described as P. betulijWa by Pursh, who further added as its station, " about Lake Ontario." The tree was probably an introduced form of the European P. nigra, and was latterly so considered by the younger Michaux himself. A few of these trees are s>till found in the neigh- borhood of Hoboken, New Jersey. P. DILATATA, Ait., the well-known pyramidal LOMBARDY POPLAR, has Deen extensively introduced as an ornamental tree, and is found in the vicinity of all old settlements. P.

I have endeavored to bring the allied groups (as I understand them) as nearly together as I could ; but this, of course, is not always practicable in any lineal arrange- ment. It might, however, have been done with much greater satisfaction on a larger and more comprehensive scale. I have retained the small artificial group Psyllophorje, from its manifest convenience, but should not have done so in a more philosophical work. Upon the whole, I am inclined to hope that the present will at least possess this one advantage over the hitherto, more artificial arrangement in general use, — that a student, when acquainted with one species of a group, will be enabled to recognize the co-species for himself, whilst a merely artificial enumeration must at times place very incongruous forms in juxtaposition. Any increased difficulty, if such there be, in commencing the study of this vast and intricate genus upon principles of natural classification, will be amply repaid by the more accurate knowledge ol structure thus obtained, than by a reliance merely on the loose external characters derived from the number and position of the spikes.- I shall be well satisfied if my attempt shall be m assistance to others in doing far better, hereaftw."
