 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

 era : 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 cm. long : leaf-blades usually less than 10 cm. broad. 1. C. Boykinii.

1. Cayaponia Boykinii (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 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 mm.

 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-
