BUDS

Observe as the scales are removed whether the sticky coating is 

 thicker on the outside or the inside of each scale, and whether it is 

 equally abundant on all the successive pairs. 

 What is the probable use of this coating? 



Note the delicate veining of some of the scales as seen through 

 the magnifying glass. What does 

 this mean? 



Inside the innermost pair are 

 found two forked woolly objects ; 

 what are these? 



Compare with Figs. 48 and 55. 

 Their shape could be more readily 

 observed if the woolly coating were 

 removed. 



Can you suggest a use for the 

 woolly coating ? 



Examine a terminal bud in the 

 same way in which you have just 

 studied the lateral bud. 



Does it contain any parts not 

 found in the other? 



What is the appearance of these 

 parts? 



What do they represent ? 

 If there is any doubt about their 

 nature, study them further on a 

 horse-chestnut tree during and im- 

 mediately after the process of leaf- 

 ing out in the spring. 



For comparison study at least 

 one of the following kinds of buds 

 in their winter or early spring con- 

 dition : hickory, butternut, beech, 

 ash, magnolia (or tulip tree), lilac, 

 balm of Gilead, cottonwood, cultivated cherry.^

 Scales to Leaves. 



1 Consult the account of the modeof studying buds in Professor W. F. Ganong's 

 Teaching Botanist, pp. 208-210. If some of the buds are studied at home, pupils 

 wDl have a better chance to examine at leisure the unfolding process.
