Characteristics

Small shrubby or medium-sized tree, up to 40 m high; bole to 15 m high, to 75 cm in diameter. Branchlets terete to slightly angular, brownish puberulous in the distal parts, glabrescent. Leaves: rachis 1.5-4.5 cm, glabrous to very scarcely puberulous, gland raised, (sub)urceolate, with a narrow orifice, 2-4 mm in diameter; pinnae 1 pair, 2.5-8 cm, scarcely puberulous; petiolules 2-7 mm, glabrous; leaflets IV2-2 pairs per pinna, proximal pair alternate, distal pair opposite, chartaceous, drying brownish, ± equal-sided, ovate-elliptic, elliptic, or obovate-elliptic, 5.5-22 by 3-12 cm; base symmetrically, asymmetrically cuneate, or rounded, apex obtuse, tip acuminate, upper surface glabrous, lower surface with scattered hairs, glabrescent; principal lateral veins 3-6 per leaflet-half, strongly arching, non-parallel, connected by secondary and tertiary lateral veins which form some trabeculate anastomoses, reticulation prominulous above, prominent beneath. Inflorescences terminal, densely rusty puberulous, consisting of pedunculate glomerules aggregated into panicles, 25 by 10-20 cm; glomerules slightly elongated, consisting of c. 5-12 sessile or subsessile flowers; floral bracts ovate or oblong, acute, c. 1.5 mm, puberulous. Flowers (tri-or) pentamerous, bisexual, fragrant. Calyx green, funnel-shaped, 3.1-4 mm, scarcely or densely puberulous; teeth 3-5, unequal, rounded, 1-1.3 mm. Corolla green or whitish, narrowly funnel-shaped, 6.5-8 mm, tube glabrous, lobes 5, unequal, narrowly ovate or oblong, acute, 2-3 mm, puberulous at the apex and often with papillose margins. Stamens white, c. 12 mm, tube shorter than the corolla-tube. Ovary solitary, glabrous. Pod brown outside, light brown within, straight, turgid, to 16 by 4 cm, only very slightly constricted between the seeds, woody-rigid-ly coriaceous, glabrous, with inconspicuous veins, dehiscing along both sutures.

A shrub or tree. It can grow up to 40 m high with a 15 m trunk which is 75 cm across. The small branches are round or slightly angular. They are brown and hairy towards the ends.

The base of these leaflets can vary from equal and round to unequal and tapering. The flower clusters are at the ends of branches. They have dense rust coloured hairs. The flower heads are 25 cm long by 10-20 cm across. These are made up of 5-12 flowers with very short stalks. The flowers can have 3-5 flower parts and have both sexes and a sweet smell.
