. Botany for young people and common schools. How plants grow, a simple introduction to structural botany. With a popular flora, or an arrangement and description of common plants, both wild and cultivated. Botany. 26 HOW PLANTS GROW YI:AR AFTER YEAR. Is I Avhen most leaves have fallen. Even then we can tell how the leaves were placed, as well as in summer. We have only to notice the leaf-scars: for each fallen leaf has left a scar to mark where its stalk separated from the stem. And in most cases the bud above each scar is now apparent or conspicuous, ready to grow into branches in the spring, and showing plainly the arrangement which these are to have. Here, for instance, is a last year's shoot of Ilorsechestnut (Fig. 54), with a large terminal bud on its summit, and with very conspicuous leaf-scars. Is; and just above each is an axillary bud, b. Here the leaves were opposite each other; so the buds are also, and so will the branches be, unless one of the buds on each joint should fail. Fig. 55 is a similar shoot of a Hickory, with its leaf-scars {I s) and axillary buds (h) alternate, that is, single on the joints and one after another on different sides of the stem; and these buds when they grow will make alternate branches. 61. The branching would be more regular than it is, if all the buds grew. But there is not room for all; so only the stronger ones grow. The rest stand ready to take their place, if those happen to be killed. Sometimes there are more buds than one from the same axil. There are three placed side by side on those shoots of Red Maple Avhich are going to blossom. There are several in a row, one above another, on some shoots of Tartarean Honeysuckle. G2. The appearance of plants, the amount of their branching, and the way in which they continue to grow, depend very much upon their character and duration. 63. The L-urafion of PltinlS of different kinds varies greatly. Some live only for a few months or a few weeks; others may endure for more than a
