Scandent shrub to large liana, sometimes a small tree. Branches subglabrous. Leaves uni-or 3-foliolate (to 2-jugate), glabrous; petiolules 0.5-0.75 cm. Leaflets oblong to elliptic, 8-17 by 4-8 cm, chartaceous; base rounded, subpeltate; apex rounded or blunt-acuminate; nerves 5-7 pairs, patent, slightly curved, not distinctly joined; veins laxly reticulate, mainly transverse. Inflorescences up to 40 cm long, thinly and minutely pubescent, branches rather short, poorly branched, ultimate branchlets subspicate with the flowers crowded near their apex. Bracts minute. Sepals oblong-lanceolate, blunt to acute, 2.5-3 by 1 mm, outside densely tomentose, inside sparsely pubescent. Petals linear-spathulate, 7 mm long, outside in the basal half sparsely tomentose, inside glandular-pubescent, densely punctate. Stamens for 0.75 mm connate, epipetalous ones probably sterile, glabrous, long filaments sometimes glandular-pubescent towards the tip. Fruits curved to falcate, flattened, 2½-3½ by 2-2¾ cm, gradually narrowed at base into an up to 1 cm long stipe, beak acute, terminal; pericarp thin, outside minutely striate, verruculose, on both surfaces sparsely pubescent.
