340. The strawberry. The receptacle of the flower becomes 

 large and fleshy, while the "seeds," which are akenes, are 

 sunk in the surface and 

 are hard and dry. The 

 strawberry thus differs 

 from the raspberry and 

 blackberry, but like them 

 it is not a true berry. 



341. The pome (apple, 

 pear, quince, etc.). In 

 the flower the calyx, 

 corolla, and stamens are 

 perigynous, i.e., they are 

 seated on the margin of 



the receptacle, Which is Fruit of^quast'apepo. 



elevated around the 



pistils. In fruit the receptacle becomes consolidated with the 

 wall of the ovary (with the pericarp). The receptacle thus rein- 

 forces the pericarp. The receptacle and outer portion of the peri- 

 carp become fleshy, while the inner portion of the pericarp becomes 



papery and forms the "core." 

 The calyx persists on the free 

 end of the fruit. Such a fruit 

 is called a pome. The recep- 

 tacle of the rose-flower, closely 

 related to the apple, is instruc- 

 tive when used in comparison. 

 The rose-fruit is called a "hip." 

 342. The pepo. The fruit 

 of the squash, pumpkin, 

 cucumber, etc., is called a pepo.

The outer part of the fruit is 

 the receptacle, which is con- 

 solidated with the outer part of the three-loculed ovary. The 

 calyx, which, with the corolla and stamens, is attached to the 

 upper part of the ovary, falls off from the young fruit.
