The American botanist and florist: including lessons in the structure, life, and growth of plants; together with a simple analytical flora, descriptive of the native and cultivated plants growing in the Atlantic division of the American union. Botany; Botany. THE rOUB STAGES OF PLANT LIFE. 15 34. By the growth of the terminal bud, the axis is simply lengthened in one direction, an undivided stem. But besides this, buds also exist, ready formed, in the axils of the leaves, one in each. These axillary buds, a j^art or all of them, may grow and develop like the terminal bud, or they may always sleep, as in the simple-stemmed Mullein or Palm. But in growing they become branches, and these branches may, in. turn, generate buds and branchlets in the axils of their own leaves in like manner. By the continued repetition of this simple process, the vegetable fabric arises, ever advancing in the direction of the growing points, itself with leaves as it advances, and en- larging the. volume of its axis, until it reaches the limit of being assigned by its Creator. 33. Reared by this process alone, the plant consists of such organs only as were designed for its own individual nourishment—roots to absorb its food, stem and branches to transmit it, and leaves to digest it. These are called organs of nutrition. But the divine command which caused the tribes of vege- tation in their diversified beauty to spring from the earth, required that each plant should have its " seed within itself" for the perpetuation of its kind. (See. 1; II.) 36. In the third stage of vegetation, therefore, a change occurs in the development of some of the buds. The grow- ing point ceases to extend it- self as hitherto, and still remains a point, expand- ing its scales in crowded whorls, each successive whorl undergoing a gradual transformation, departing more and more from the original type—the leaf. Thus, instead of a leafy branch, the ordinary product of the bud, a flower is the result.
