H- Leaves palmately lobed : flower widely spreading. 



P. gracilis. Slender herb, with roundish and slightly 3-lobed otherwise 

 entire leav.es, and whitish merely 5-cleft flower only 1' in diameter, destitute of 

 true petals. Recently introduced, remarkable for the quick movement of its 

 tendrils.

 deeply cleft or parted into 5 or 7 lance-oblong entire divisions, pale ; and flower 

 almost white, except the purple centre and blue crown banded with whitish in

52. CUCURBITACE^S, GOURD FAMILY. 



Mostly tendril-bearing herbs, with succulent but not fleshy herb- 

 age, watery juice, alternate palmately ribbed and mostly lobed or 

 angled leaves, monoecious or sometimes dioecious flowers ; the calyx 

 coherent with the ovary, corolla more commonly monopetalous, 

 and stamens usually 3, of which one has a 1-celled, the others 

 2-celled anthers; but the anthers are commonly tortuous and often 

 all combined in a head, and the filaments sometimes all united in 

 a tube or column. Fruit usually fleshy. Embryo large, filling the 

 seed, straight, mostly with flat or leaf-like cotyledons. Besides 

 those here described, there are occasionally cultivated for curiosity 

 the following annuals : 



MOMORDICA ELATERIUM or ECBALIUM AGRESTE, the SQUIRT- 

 ING CUCUMBER, a homely hairy herb without tendrils, and pro- 

 ducing an oblong hairy pulpy fruit (of violently purgative qualitie-), 

 which when ripe bursts suddenly at the touch, and discharges the 

 contents with violence (whence the name Ecbalium). 



TRICHOSANTHES COLUBRINA, SNAKE-CUCUMBER or VEGE- 

 TABLE SERPENT, a tall climber with the staminate flowers orna- 

 mental, the lobes of the white corolla being cut into a lace-like 

 fringe of long and very delicate capillary lobes (whence the name 

 of the genus), and the fruit very like a snake, 8 or 4 feet long, 

 green and striped, turning red when ripe. 



1. Flowers larc/e or middle-sized, on separate simple peduncles in the axils: anthers 

 with tony and narrow celts, bent up and down or contorted: ovules and seeds 

 many, horizontal, on mostly 3 simple or double placentae, : fruit (of the sort 

 called a pepo) large, fleshy or pulpy with a harder rind. 

 * Both kinds of flowers solitary in the axils. 



1. LAGENARIA. Tendrils 2-forked. Flowers musk-scented, with a funnel-form 

 or bell-shaped calyx-tube, and 5 obcordate or obovate and mucronate white 

 petals ; the sterile on a long, the fertile on a shorter peduncle. Anthers lightly 

 cohering with each other. Stigmas 3, each 2-lobed. Fruit with a hard or 

 woody rind and soft flesh. Seeds margined. Petiole bearing a pair of glands 

 at the apex.
