Scandent shrub to climber. Branchlets terete, tomentose to puberulous, glabrescent, armed with prickles; prickles unpaired, hook-like, to 5 mm, emerging from the bases of the leaf-scars. Stipules filiform, 2-3 mm. Leaves: rachis 10-15 cm, tomentose, with a gland c. 0.5 cm above the base and additional glands at the junctions of the 1-6 distal pairs of pinnae, petiolar gland, elliptic, flat to concave, sessile, c. 2(-5) mm; rachis-glands smaller, circular; pinnae 8-20 pairs, opposite, c. 3.5-5.5 cm, tomentose, with a gland at the junction of the distal pair of pinnae, or absent, narrowly elliptic, sessile, flat, c. 0.5 mm; leaflets opposite, chartaceous, sessile, 25-60 pairs per pinna, narrowly oblong to linear, 0.4-0.8 by 0.08-0.2 cm, base asymmetrically truncate, apex rounded to broadly acute; both surfaces puberulous, glabrescent, with hairs scattered along the margin, main vein subdiagonal. Inflorescence composed of pedunculate glomerules aggregated into terminal, tomentose panicles; peduncles to 1.5 cm long, in clusters of 3 or 4, to 1.5 cm, with glomerules of c. 10-12 flowers. Flowers sessile, dimorphic, pentamerous, bisexual. Calyx funnel-shaped to campanulate, c. 0.75 mm, puberulous; teeth triangular, acute, c. 0.25 mm. Corolla funnel-shaped, 3.5-5.5 mm, sparsely sericeous; lobes ovate to ovate-elliptic, 1-2 mm. Stamens white, tube equalling the corolla-tube. Ovary c. 1 mm, glabrous, stipe c. 1-1.5 mm. Pod yellowish to brownish, oblong, flat, chartaceous, c. 14 by 2.5 cm, glabrous, dehiscing first along the ventral suture, with distinct marks over the seeds, and with inconspicuous transverse veins.
