Tree to 25 m high, to 40 cm in diameter. Branchlets terete, glabrous, lenticellate. Stipules and stipular glands absent. Leaves: rachis 1-7.5 cm, glabrous; glands ± circular, flat, sessile, often sunken, without raised margins, 1-3 mm in diameter; pinnae 1 pair, 4-17 cm, glabrous; petiolules 4-5 mm, glabrous; leaflets 1½-3 pairs per pinna, opposite, the lower leaflet sometimes unpaired, rigidly chartaceous-coriaceous, drying grey-green, equal-sided, broadly elliptic, 3.7-17 by 2-11 cm, base symmetrically cuneate, somewhat tapering, apex rounded or obscurely acuminate, both surfaces glabrous; principal lateral veins 4 or 5 per leaflet-half, arching, reticulation prominent on both surfaces. Inflorescences terminal or axillary at the distal leaves, glabrous, consisting of pedunculate umbels aggregated into panicles to 10 cm; peduncles 1-2 cm, umbels consisting of up to 8 pedicellate flowers, pedicels 3-5 mm, floral bracts ovate, broadly acute, 1-2 mm, glabrous. Flowers tri-or tetra-merous, female or bisexual. Calyx green, broadly tubular or narrowly campanulate, 7-11 mm, glabrous; lobes ovate, obtuse, c. 1-2 mm, or calyx occasionally split further down. Corolla green, narrowly funnel-shaped, 22.5-30 mm, glabrous; lobes oblong-lanceolate, acute, often unequal, 6-8 mm. Stamens white, to 40 mm, tube equalling the corolla. Ovary solitary, glabrous, sessile. Pod bright red, slightly curved, flattened or subterete, 4.5-9 by 1.7-2.5 cm, coriaceous or woody, sometimes constricted between the seeds due to abortion of some ovules, glabrous, veins inconspicuous, dehiscing along both sutures. Seeds black, ellipsoid, c. 15 by 10 mm.
