Melon or Pepo Type. In the Melons, Cucumbers, Pump- 

 kins, and Squashes, which illustrate well the pepo type, the 

 ovaries are inclosed in the receptacle, and with the receptacle to

which they are closely joined form the rind. (Fig. 78.) The 

 placentas are more or less fleshy and in case of the Watermelon, 

 where they form large juicy lobes, they constitute the bulk of 

 the edible portion. In most cases, however, as Muskmelons and 

 Pumpkins illustrate, the placentas break 

 loose from the ovary wall and are removed 

 with the seeds. In what way does the 

 Melon resemble the Apple in structure? 

 How does it differ from the Apple? 



Strawberry Type. In the Strawberry 

 the ovaries develop into hard one-seeded 

 fruits (akenes) which appear as small hard 

 bodies over the surface of the much flesh- 

 ened receptacle. (Fig. 79.) In the Straw- 

 berry, although the ovaries are included 

 when the fruit is used, the edible portion 

 is the receptacle. 



Blackberry Type. In this type the 

 ovaries develop as small stone fruits, often 

 called drupelets (miniature drupes), and 

 with the fleshened receptacle form the 

 fruit. (Fig. 80.) Very similar to the Blackberry is the Rasp- 

 berry, in which the drupelets collectively separate from the re- 

 ceptacle and thus alone form the fruit.
