BUDS

the leaf with the stem (Latin axilla, armpit). But not infre- 

 quently there are several buds grouped in some way about 

 a single leaf-axil, either one above the other, as in the 

 butternut (Fig. 61), or grouped side by side,, as in the red 

 maple, the cherry, and the 

 box-elder (Fig. 50). 



In these cases all the 

 buds except the axillary 

 one are called accessory or 

 supernumerary buds. 



109. 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. 



(6) 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 stem.
