Description

Woody vine ca. 8 m long. Stems terete, striate, puberulent or pubescent, becoming glabrous and lenticellate with age; cross section with a single vascular cylinder. Stipules minute, inconspicuous. Leaves trifoliolate or less often pinnately 5-foliolate; petioles unwinged, margined, puberulent, 2-4.5 (-7) cm long; petiolules 2-5 mm long; leaflets chartaceous, glabrous, sparsely puberulent and subbarbate at vein angles abaxially, elliptic or oblong-elliptic, 5-11 × 2-4 cm (distal leaflet larger), the base acute or attenuate, the apex nearly rounded, with short obtuse apiculum, the margins remotely crenate-serrate; tertiary veins subclathrate. Thyrses axillary, racemiform, minutely tomentulose, ca. 10 cm long; bracts and bracteoles deltate, minute; cincinni sessile, few-flowered. Sepals 4, ca. 2 mm long, ovate, appressed-pubescent, anterior sepal cleft to about half way; petals ca. 2 mm long, obovate. Capsule glabrous, ca. 1 cm long, long-stipitate, nearly globose or ellipsoid, with 3, spreading, narrow wings near the apex, the locule red, the wings greenish, ca. 8 mm long.
