a single leaf-axil, either one above the other, as in the 
butternut (Fig. 51), or grouped side by side, as in the red 
maple, the cherry, and the 
box-elder (Fig. 50). 
In these cases all the

the smallest of the series. 
(c) The axillary buds found in the angles made by some leaves 
with the stem.
