1. Cucurbita foetidíssima H.B.K. Perennial by large fusiform roots, stout, rough- 
pubescent, with a heavy foetid odor. Stems trailing or climbing, 1-5 m. long, angled: 
leaf-blades thick, triangular or triangular-ovate, acute or acutish, 1-4 dm. long, distantly

2. Cucurbita Texana (Scheele) A. Gray. Similar to C. foetidissima in habit, but 
more slender. Leaf-blades 3-5-lobed, sometimes deeply so: berries pyriform. Perhaps a 
naturalized form of C. Pepo.

8. CAYAPONIA Manso. 
Perennial glabrous or pubescent vines, climbing by simple or compound tendrils. 
Leaf-blades 3-7-lobed, or rarely divided, or the upper one sometimes entire. Flowers 
monoecious or dioecious, rather small, in clusters, racemes or panicles or sometimes soli- 
tary : staminate with a campanulate hypanthium and a 5-lobed calyx ; corolla white or 
yellowish green, campanulate or rotate, 5-lobed ; stamens 3; filaments distinct ; anthers 
cohering above. Pistillate flowers with calyx and corolla like those of the staminate flow- 
ers: staminodia 3. Ovary 3-celled: stigmas 3, dilated. Ovules 1 to 4 in each cavity, 
ascending. Berry more or less fleshy, usually 3-seeded. Seeds erect, with a hard testa. 
Berries oval, less than 1.5 em. long : leaf-blades usually less than 10 em. broad. 1. C. Boykinii.. 
Berries oblong, over 1.5 em. long : leaf-blades usually over 10 em. broad. 2. C. grandifolia. 
1. Cayaponia Boykínii (T. & G.) Cogn. Stems climbing, 3-6 m. long, angled, 
branched : leaf-blades thickish, scabrous on both surfaces, 5-10 cm. broad, 3-angled or 3- 
lobed, distantly toothed, cordate, the lobes apiculate, or the terminal one short-acuminate ; 
petioles about 4 as long as the blades, bristly villous : flowers small, 3-5 of the staminate 
and pistillate usually together, short-pedicelled : sepals triangular or lanceolate-triangular, 
1-2 mm. long: corolla greenish white, 5-6 cm. broad ; lobes ovate or ovate-lanceolate : 
berries oval, 12-14 mm. long, rounded at the ends, crimson, their pedicels about 2 rs 
long: seeds elliptic, 8-10 mm. long, abruptly pointed at the base and with 2 lateral auricie- 
like teeth. 
Along streams, Georgia to Louisiana. Summer. n 
2. Cayaponia grandifdlia (T. & G.) Small. Stems stoutish, climbing by simple or 
branched tendrils 2-5 m. long, angled, much branched: leaf-blades thin, scabrous on 
both surfaces, 3-lobed, distantly and minutely toothed, cordate, the terminal lobe ovate 
acuminate, the lateral lobes sometimes angled, slightly lobed again ; petioles less than $a -
