water-melon like: Us. small, the pistillate long-stalked: 

 fr. 1-3 in. long, cucumber-like but more spiny. Supposed 

 to be native to the Amer. tropics. B.M. 5817. Cult, both 

 for the oddity of its frts. and for the making of pickles. 

 The (Jherkius of mixed pickles, however, are young 

 Cucumbers.

CUCURBITA (classical name). Cucur- 

 bit acece. GOUKD. PUMPKIN. SQUASH. Vine- 

 like herbs, tendril-bearing, inhabitants of 

 warm countries. Fls. monoecious, large, 

 yellow, solitary in the axils, the stam- 

 inate long stalked, the pistillate short- 

 stalked : corolla 5-lobed : stamens 3. 

 arising from the bottom of the fl., and united in a 

 column : stigmas 3, but 2-lobed : ovary inferior, en- 

 closing a hollow receptacle: tendrils 2-3 forked. About 

 10 species. The morphology of the Pepo or Gourd-fruit 

 may be illustrated by the Turban Squash. (Figs. 592, 593, 

 594.) In this fruit, there is a ' squash inside a squash." 

 The inner part bears the corolla and the styles. It is the 

 ovary. The corolla is attached about the edge of the

inner Squash, as the withered remains in Fig. 592 show. 

 Sometimes the withered corolla becomes detached, but 

 hangs onto the withered remains of the stigmas, as in 

 Fig. 593. The longitudinal section of the flower (Fig. 

 594) explains the structure. The corolla is shown at c d. 

 The top of the ovary is at O. The stigmas are on the 

 ovary. The part encircling the ovary (outside of O) is 

 the hollowed receptacle. Ordinarily the receptacle is 

 closed at the top, completely confining the ovary; but 

 in the Turban Squashes the receptacle does not extend 

 over the top of the ovary, and 

 the ovary therefore protrudes. 

 The older morphologists held 

 this outer part of the Squash to 

 be adnate calyx, rather than re- 

 ceptacle. The Cucurbits are
