65. Opening of the 

 pear bud. 



it does not. The length of the shoot usually depends more 



on the lengths between joints than on the number of leaves. 

 94. How Buds Open. — When the bud 



swells, the scales are pushed apart, the 



little axis elongates and pushes out. In 



most plants, the outside scales fall very soon, 



leaving a little ring of scars. Notice peach, 



apple, plum, willow, and other plants. 



(Fig. GO.) In others, all the scales grow 



for a time, as in the pear. (Figs. 61, 62.) 

 In other plants, the inner bud- 

 scales become green and al- 

 most leaf-like. See the maple 

 and hickory. Fig. 63 shows a 

 hickory bud. Two weeks later, 

 the young shoot had pushed out 

 and the enlarged scales were hanging. (Fig. 64.) 

 95. Sometimes flowers come out of the buds. 

 Leaves may or may not accompany the flowers. 

 We saw the embryo flowers in Fig. 56. The 

 bud is shown again in Fig. 61. In Fig. 62 it is 

 opening. In Fig. 65 it is 



more advanced, and the woolly un- 

 formed flowers are appearing. In 



Fig. 66 the growth is more advanced. 



In Fig. 67 the flowers are full blown; 



and the bees have found them. 



96. Buds that contain or produce 



only leaves are leaf-buds. Those that 



contain only flowers are flower-buds 



or fruit-buds. The latter occur on 



peach, almond, apricot, and many 



very early spring-flowering plants. 67 - p,:u '" '"" bloom -
