Shrub or small tree up to 4 m high. Branchlets terete, glabrous. Stipules not seen; stipular glands linear, very inconspicuous, c. 1.5 mm. Leaves: rachis (2.5—)3—10(—13) cm, puberulous or glabrous, glands circular, slighdy raised, flat, 1-2 mm in diameter; pinnae 1 pair, 3-18(-28) cm, puberulous or glabrous, glands circular, without raised margins, sometimes slightly concave, c. 1-1.5 mm in diameter; petiolules 3-5 mm, scarcely to densely puberulous; leaflets c. 2-4 pairs per pinna, opposite and often with an additional lower leaflet unpaired, chartaceous, drying grey to dull brown, equal-sided, ovate-elliptic, elliptic, or oblong-lan-ceolate, 7-31 by 3-10 cm, base symmetrically cuneate, apex shortly blunt-acuminate (or caudate), both surfaces glabrous; principal lateral veins 2 or 3 per leaflet-half, strongly arched, the lower occasionally forked in the proximal part, veins parallel to the margin of the leaflet for more than halfway, tertiary veins scalariform, reticulation prominent. Inflorescences cauliflorous or ramiflorous, glabrous or densely puberulous, probably not pendulous, consisting of racemosely arranged umbels of 1-5 flowers, floral bracts inconspicuous, oblong-linear, 0.5-1 mm; pedicel 5-12 mm, glabrous. Flowers pentamerous, male and bisexual, pale green. Calyx cupular, 1-2 mm, with crenulate margin, glabrous. Corolla broadly funnel-shaped, 3.5-6.5 mm, glabrous; lobes ovate, acute, 2 mm, glabrous. Stamens white, (10-)20-30 mm, tube equalling the corolla-tube. Ovaries solitary or absent in male flowers, 2-3 in bisexual flowers, glabrous. Pod red, curved into a circle or spirally contorted, up to 10 by 1.5-2 cm, coriaceous, sometimes strongly constricted between the seeds due to abortion of some seeds, compartments oblong, c. 1 cm long, 2 cm wide, glabrous, veins invisible, dehiscing first along the dorsal suture. Seeds black, obovoid, slightly compressed, c. 12 by 8 mm.
