I. CUCURBITACEjE, GOURD FAMILY. 



Mostly tendril-bearing herbs, with succulent but not fleshy 

 herbage, watery juice, alternate palmately ribbed and mostly 

 lobed or angled leaves, monoecious or sometimes dioecious 

 flowers ; the calyx coherent with the ovary, corolla more com- 

 monly 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 tuba or column. Fruit 

 usually fleshy. Embryo large, filling the seed, straight, mostly 

 with flat or leaf-like cotyledons. 



1. Flowers large or middle-sized, on separate simple peduncles in the axils ; anthers 

 with long and narrow cells, 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- seen ted, 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 8, each 2-lobed. Fruit with a hard or woody rind and soft flesh. 

 Seeds margined. Petiole bearing a pair of glands at the apex. 



2. CUCURBITA. Tendrils 2-5-forked. Flowers large, with a bell-shaped or short funnel- 



form 5-cleft yellow corolla, its base adherent to the bell-shaped tube of the calyx. 

 Stamens from the bottom of the flower ; anthers long-linear, much curved, all three 

 united into a small head. Stigmas 3, each 2-lobed. Fruit fleshy with a tinner rind. 

 Seeds mostly margined. 



8. CITRULLUS. Tendrils 2-3-forked. Flowers with a short bell-shaped calyx tube, and 

 a deeply 5-cleft, widely open, pale yellow corolla. Stamens with very short filaments ; 

 anthers lightly cohering. Stigmas 3, kidney-shaped. Seeds margiuless, imbedded in 

 the enlarged pulpy placentae. 



* * Sterile flowers clustered, fertile ones solitary in the axils. 



4. CUCUMIS. Tendrils simple. Corolla of 5 almost separate, acute petals. Stamens 



separate ; anthers with only one bend. Stigmas 8, blunt. Fruit with a fleshy rind. 

 Seeds not margined. 



2. Flowers of one or both sorts in racemes, panicles, corymbs, or long-stalked 

 clusters. 



* Fruit large and gourd-like ; flowers large. 



5. LtJFFA. Flowers cream-colored or orange, with obcordate or obovate petals; the 



staminate ones in a raceme on a long stalk ; the pistillate, solitary and peduncled. 

 Tendrils variously branched. Fruit long-cylindrical, dry when ripe, green, the
