Genus of several species, and spread through the hot regions of the globe. 



1. V. LUTEA Gray. (Enum. No. 113.) A prostrate vine, several 

 feet long. Peduncles, petioles, and leaves hirsute with scattered hairs 

 when young, soon glabrous. Leaflets obovate or orbicular, very ob- 

 tuse, or even retuse, somewhat tapering at the base, triplinerved, 2' -4' 

 long and as wide or nearly so. Racemes on short peduncles, not as 

 long as (often much shorter than) the leaves, few-flowered. Flowers 

 yellowish, 6" -7" long, on pedicels l"-2" long. Calyx-lobes broad 

 and obtusish. Pod li'-3' long, not much compressed. Seeds several, 

 chestnut-brown.

2. V. OAHUENSIS Vogel. (Enum. No. 114.) Plant with much the 

 habit of the last. Peduncles, petioles, &c., sericeous when young. 

 Leaves ovate, usually acute, rounded at the base, not triplinerved, but 

 rather strongly parallel-veined, glabrous on both sides, l' long, 1' or 

 more wide. Flowers about 7" -8" long. Calyx-lobes broad, acute, or

 also the petioles and peduncles ; the leaves pubescent on both sides in 

 a similar manner. Stipules and stipellae subulate, minute. Leaflets
