Buds that contain or 

 produce only leaves are 

 leaf-buds. Those which contain only flowers are flower- 

 buds or fruit-buds. The latter occur on 

 peach, almond, apricot, and many very 

 early spring-flowering plants. The 

 single flower is emerging from the 

 apricot bud in Fig. 147. A longi- 

 tudinal section of this bud, enlarged, is 

 shown in Fig. 148. Those that contain 

 both leaves and flowers are mixed buds, 

 as in pear, apple, and most late spring- 

 flowering plants. 



Fruit buds are usually tliicker or 

 stouter than leaf-buds. They are borne 

 in different positions on different plants. 

 In some plants (apple, pear) they are 

 on the ends of short branches or spurs; 

 in others (peach, red maple) they are 



along the sides of the last year's
