 This species differs from C. race>nos<i, Jacq., in having smaller acumi- 

 nate leaves, entire bracts, more slender calyx-lobes, smaller corolla, more 

 slender habit, and a much reduced raceme ; from C. hrachiata, R. & P., 

 in smaller, narrow leaves, in much reduced simple raceme, and slightly 

 smaller flower.

 4-seeded. Seeds ovoid with a broad neck at one end.

Cucurbitaceous and allied to Anguria and Gurunia. It is strikingly 

 different, however, in having the pistillate and staminate flowers of une- 

 qual size as in Melolkria, and in having a distinctly spicate inflorescence, 

 a cliaracter rare or entirely lacking in other Cucurbit aceae. 



A. margaritensis, n. sp. Stem climbing, somewhat woody ; tendrils

 margin crenate-dentate; upper surface green, lightly hispid; under surface 

 densely velvety-pubescent, whitish ; the largest leaves varying from 

 12 mm. wide and 18 mm. long to 15 mm. wide and 12 mm. long, un- 

 doubtedly becoming larger ; petiole pubescent, 1 cm. long : inflorescence
