Description : Tree up to 20 m high; branchlets terete, glabrous. Leaves: rachis 2–7 cm, gland (s) ca 0.5 cm above the base of the petiole and between the junctions of the pinnae, 1.5–2 mm diam., subsphaerical to flat and circular, sessile; pinnae 1 pair, up to 20 cm, glands (often absent) between the junctions of the petiolules, 0.75–1 mm diam., flat, circular, sessile; leaflets 2–3 pairs per pinna, petiolulate, opposite, chartaceous, up to 8–15 by 4–5 cm, ovate-elliptic to oblong; base broadly rounded to broadly cuneate, apex acuminate; both surfaces glabrous, lateral veins prominulous, not forming a dense reticulation. Inflorescence: panicles in the axils of the upper leaves, or below the leaves, at the leaf-scars on the older branches; peduncles ca 3 mm bearing heads of 4–7 sessile flowers. Calyx 1–2 mm, broadly campanulate to cup-shaped, faintly puberulous, with 0.25–0.3 mm, deltoid teeth. Corolla 4–5 mm, tube glabrous, with ca 2 mm ovate-elliptic acute, reflexed lobes with distinct veins, lobes faintly puberulous to glabrous. Staminal tube as long as the corolla tube. Ovary ca 1 mm, glabrous; stipe ca 2 mm. Pod: up to 20–25 by 4 cm, compressed, falcate or twisted in a wide spiral more or less deeply lobed along the ventral suture between the seeds, woody, greyish outside and inside, glabrous, dehiscent along the ventral suture. Seeds fill the pod, ca 35 mm diam., and 10 mm thick, biconvex, circular, with a dark brown, thin testa.
