Tree to 24 m high, d.b.h. 50 cm. Branchlets terete, densely shortly puberulous. Stipules triangular, rigid, caducous, c. 0.8 mm. Leaves: rachis 6.5-30 cm, puberulous, with a gland 0.5-2 cm above the base, circular to elliptic in outline, raised, with a narrow orifice, c. 2.5 mm in diameter, and with a similar but smaller gland at the junction of the distal pair of pinnae; pinnae 2-6 pairs, puberulous, (2-)4.8-12 cm, with (2-)3-7 pairs of leaflets; petiolules 1-1.5 mm, puberulous; leaflets opposite, chartaceous, obliquely obovate, elliptic, or subtrapezoid, 1-5 by 0.6-2.2(-2.5) cm; base asymmetrically cuneate, apex rounded, mucronate, both surfaces finely appressed puberulous; main vein subcentral or subdiagonal.

Flowers bisexual, cream, pentamerous. Calyx tubular, finely appressed puberulous, 3 mm; teeth inconspicuous. Corolla narrowly funnel-shaped or ± subtubular, 6.8-7 mm, tube glabrous; lobes oblong, acute, 2 mm, finely appressed puberulous. Stamens c. 15-17 mm, tube longer than the corolla tube, shorter than the corolla. Ovary 1.5 mm, glabrous, subsessile.
