BLACKBERRY TYPE 79 
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 
' Fic. 79.— Flower and fruit of Strawberry. A, section through flower, 
showing the fleshy receptacle (r) and the many pistils (p) on its surface. 
B, fruit consisting of enlarged receptacle (r), bearing the small hard ovaries (0). 
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 Soe ee ee 
ovaries develop as small stone fruits, often Blasters. wees 
called drupelets (miniature drupes), and ¢e- f feshened ovaries. 
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.
