as the apple, or dry 

 fruits, like the bean. 

 Pods and other fruits 

 which open in a definite 

 way are called dehiscent 

 (Latin, dehisco, to split 

 open) fruits. Poppies, 

 pansies, and violets have 

 dehiscent fruits called 

 capsules. Nuts, corn, and 

 wheat are examples of 

 indehiscent fruits (Fig- 

 ures 323 and 324). 



Fleshy fruits fall into 

 three groups : (1) pome 



fruits, apples and pears which have the seeds in a core in the 



middle surrounded by a thick, fleshy part (Figure 325); 



(2) drupes, or stone fruits represented by the plum, which 



has the seed inclosed in a hard stone surrounded by soft 



pulp; and (3) berries, fruits in which the seeds are scat- 

 tered through the pulp, as in 



the grape, currant, or orange 



(Figure 327). Most of the 



fruits commonly called berries 



are really collections of small 



drupes. In the strawberry each 



" seed " is a fruit, and the fleshy 



substance is the receptacle of 



the flower, which has been 



greatly enlarged. In the case 



of the blackberry, as well, the 



receptacle is eaten, for the drupes 



cling- to it as it is removed from 



& Figure 328. — Forms of Dehis-
