Liana, up to 8 m by 2 cm, sometimes scandent shrub or treelet. Branches sparsely ferruginous-tomentose to glabrous. Leaves (1-)2-3-jugate, the petiole, rhachis, and petiolules with a few scattered hairs; petiolules 3-4 mm long. Leaflets ovate or elliptic to oblong, 2½-11(-17) by 1¼-5½ cm, chartaceous, blackish-verrucose on both sides when dry, especially beneath (probably representing the internal glands), glabrous; base broadly cuneate to rounded; apex tapering caudate-acuminate, blunt; nerves (3-)4-5 pairs, ascending, strongly curved, not rarely distinctly looped and joined; veins laxly transverse-reticulate to transverse and rather dense. Inflorescences c. 20-40 cm long, densely ferruginous-tomentose, laxly to densely branched, branches up to 20 cm long, many-flowered. Bracts minute. Sepals elliptic, blunt, 2.5-3 by 1.25 mm, keeled, densely tomentose outside, inside glabrous. Petals lanceolate, blunt, 4½-6 mm long, outside densely, inside in the upper half thinly tomentose, densely punctate. Stamens for 0.5 mm connate, all fertile, episepalous filaments with a few glandular hairs. Fruits obovoid, slightly compressed, 2.5 by 1.75 cm, stipe 0.25 cm, beak minute, lateral, usually inserted at about 2/3 of the height, pericarp thin, outside diagonally striate, glabrous, inside sparsely to rather densely shortly pubescent.
