Liana, up to 25 m high, or scandent shrub. Branches densely ferruginous-pubescent, as are the petiole, rhachis, and petiolules. Leaves 1-4-jugate; petiolules 0.25-0.5 cm long. Leaflets lanceolate (lower ones) to lanceolate-ovate or oblanceo-late (upper pairs), 7.5-27 by 2.5-9 cm, stiff-chartaceous to subcoriaceous, pubescent, at least on the nerves beneath; base rounded to cuneate, usually subpeltate; apex slightly, shortly, and bluntly acuminate; nerves (8-) 10-18 pairs, straight to slightly curved, dense and parallel, nearly always distinctly looped and joined close to the margin; veins transverse to the nerves, usually rather dense. Inflorescences up to 45 by 30 cm, densely ferruginous-tomentose, many-flowered. Bracts cylindrical, incurved, up to 1½ cm long. Sepals elliptic, acute to blunt, 2-2.5 by 1-1.25 mm, not to distinctly keeled, outside densely pubescent, inside glabrous. Petals lanceolate, blunt to slightly emarginate at the apex, 5½- long, outside glabrous except sometimes a few glandular hairs at the apex, inside glabrous or in the upper part sparsely capitate-glandular pubescent, punctate. Stamens 0.5 mm connate, epipetalous ones usually fertile, filaments glabrous or glandular-pubescent. Fruits obovoid, rather flattened, 3.5-5 by 2-4 cm, not or only shortly (up to ¾ cm) stipitate; beak usually distinct, acute, at about ⅔ of the height; pericarp obliquely wrinkled, outside densely minutely ferruginous-tomentose, glabrescent, woody, c. 1 mm thick, inside densely ferruginous-pubescent.
