Much-branched shrub or tree, 2.4-8(-20) m high, bole to 13 m tall, to 60 cm in diameter. Branchlets terete, greenish, glabrous. Stipules absent but stipular glands present. Leaves: rachis 10-55 cm, glabrous, with one gland, circular or elliptic, usually depressed, without raised margins, 1-4 mm long; pinnae 2-3(-4) pairs, to 12 cm long, glabrous, glands circular, 1-2 mm in diameter, with depressed central part, margins sometimes ± raised and swollen; petiolules black, 4-5 mm, glabrous; leaflets (l-)2-4 pairs per pinna, opposite, coriaceous, drying glossy pale yellowish green, unequal-sided, ovate, elliptic, obovate-ellip-tic, or lanceolate, (5.2-)7-18(-23) by 3.5-9(-15) cm, base slightly asymmetrical, broadly cuneate to subtruncate, apex acuminate, both surfaces glabrous, principal lateral veins (4-)6-7 per leaflet-half, arching, non-parallel; reticulation dense, prominent on both surfaces. Inflorescences usually cauliflorous or ramiflorous, sometimes terminal, glabrous, consisting of pedunculate umbels aggregated into racemes or panicles to 30 cm long; umbels 2-5-flowered; pedicels 2-7 mm; floral bracts absent. Flowers pentamerous, bisexual or possibly also male or female. Calyx greenish or dark glossy green, tubular or broadly campanulate, (5.5-)6-12 mm, glabrous; teeth broadly triangular, acute, up to 3 mm. Corolla white or greenish yellow, tubular or narrowly funnel-shaped, (17-)20-35 mm, glabrous; lobes curved backwards, triangular-ovate or oblong, acute, (4-)7-10 mm. Stamens silky-white, 40-75 mm, tube exserted. Ovaries 2-6, glabrous. Pod ± red outside, orange within, nearly straight or contorted into a circle, 10-20 cm long, 2(-3) cm wide, woody or fleshy, divided into (nearly) separate compartments, sinuate, glabrous, veins inconspicuous, pod dehiscing along the dorsal suture (or possibly indehiscent). Seeds black or bluish-black with a whitish bloom, obovoid or ellipsoid, ± compressed, c. 10-16 by 8-10 mm.
