Small myrmecophilous tree to 5 m high. Branchlets terete, lenticellate, hollow, short-puberulous, probably glabrescent. Stipules absent; stipular glands circular, concave with raised margins, 1-1.5 mm in diameter. Leaves: rachis to 22.5 cm, puberulous by short patent hairs, glands saucer-shaped, with strongly raised margins, sessile, 2.5-3 mm in diameter, pinnae probably one pair, up to 35 cm, densely short-pubescent, glands similar to rachis-glands, c. 2-2.5 mm in diameter; petiolules 5-6 mm, black, patently puberulous; leaflets up to 5 pairs per pinna, opposite, chartaceous, ± equal-sided, elliptic-ovate to oblong-lanceolate, 14.5-21 by 8-9 cm, base symmetrically cuneate, apex acuminate, both surfaces glabrous except for a few scattered hairs on the major veins; principal lateral veins c. 7 per leaflet-half, arching, non-parallel; reticulation prominulous above and prominent beneath. Inflorescences ?dioeceous, cauliflor-ous or supra-axillary in the younger branches, densely pubescent by patent hairs, consisting of unbranched or once-branched racemes, 2-5(-8) cm, with the flowers in the distal parts; floral bracts c. 2 mm, with basal nectary; pedicel up to 3 mm, minutely puberulous. Flowers pentamerous, probably bisexual, white. Calyx cup-shaped, 3 mm, minutely puberulous, broadly irregularly lobed to 0.5 mm. Corolla funnel-shaped, (9-) 12-13 mm, glabrous; lobes oblong, acute, 4 mm. Stamens at least 25 mm, tube equalling the corolla-tube. Ovaries 3, glabrous, surrounded by a tubular nectary. Pod (acc. to Harms, l.c.) short and thick, oblong or ovate, 3-6 by 2-4 cm, sometimes divided into two short, thick, 1-seeded segments. Seeds unknown.
