BERRIES 



[CH. 



the hard stone, which is here the true seed, must be care- 

 fully distinguished from the stone of a Drupe, which is 

 the bony endocarp enclosing the seed. 



The fruit of the Melons, Cucumbers, Gourds, &c. is 

 often termed a Pepo, but although the firmness of the 

 epicarp is insisted on, it is, as is also the Pomegranate, 

 really a Berry. In the same way the superior Berry of 

 the Orange, edible Lime, Lemon, &c. is often called 

 a Hesperidium, while the inferior one of the Apples, 

 Pears, &c. is termed a Pome (Fig. 6).
