Leaf-Buds and Flower-Buds; the Bud an Undeveloped Branch.— Such buds as the student has so far examined for himself are not large enough to show in the most obvious way the relation of the parts and their real nature. The cabbage, however, is a gigantic terminal bud which illustrates perfectly the struc- ture of buds in general. Examine and sketch a rather small, firm cabbage, preferably a red one, which has been split lengthwise through the center and note : (a) The short, thick, conical stem ending in layers of rapidly dividing cells, the growing apex, the source of new leaves, and length- ening of the stem. (V) The crowded leaves which arise from the stem, the lower and outer ones largest and most mature, the upper and innermost ones the smallest of the series. (c) The axillary buds found in the angles made by some leaves with the Fig. 50. Accessory Buds of Box- Elder (Negundo). (Magnified.)
