Tree 6-18 m tall, or sometimes multi-stemmed, to 4.5 m; bark grey, smooth, lightly longitudinally fissured and sometimes peeling in rectangular pieces. Branchlets grey, smooth, becoming grey with fine longitudinal cracks and red-brown lenticels, or entirely red-brown, sparsely pubescent, soon glabrescent. Leaves paripinnate, unijugate; stipules 3-4 x 2-2.5 mm, ovate to elliptic, early caducous; petiole 0.9-2.2 cm long, glabrous; leaflets 3.2-7(9) x 2-4.5(6.5) cm, ovate, asymmetric, apex rounded to acute, base rounded, glabrous; one major and 3-4 veins arising from the base, venation prominulous on both surfaces, resin vesicles in areolae few or none. Occasionally leaflets are fused to give a unifoliolate very broadly ovate leaf with a cordate base (e.g. Barbosa & Balsinhas 5101). Inflorescences axillary and terminal, paniculate; axis terete, pubescent with a mixture of longer and shorter hairs; bracts and bracteoles very early caducous (not seen). Flowers 6-7 mm long; pedicels 1.5-2 mm long, terete. Calyx lobes 4, c. 6 x 2-4 mm, elliptic, glabrous and with numerous resin vesicles outside, puberulous inside. Petals absent. Stamens 10; filaments c. 6 mm long, glabrous; anthers dorsifixed. Ovary 2-ovulate, c.1 mm diameter, subcircular, glabrous; stipe very short, with a few spreading hairs; style c. 3 mm long, glabrous; stigma capitate, bilobed. Pod 3.5 x 2.5 cm, broadly elliptic-oblong, slightly asymmetric, flattened, glabrous, the wall chartaceous, with numerous small resin-dots, 1-seeded, indehiscent, with a small very narrowly ovate dorsal wing adjacent to the style remnant. Seed dark brown, shiny, c.22 x 18 mm, broadly elliptic, flattened, exarillate. Germination epigeal; cotyledons suborbicular to depressed-elliptic, slightly asymmetric, 4-6-nerved from the base, hypocotyl and petiolules pubescent. First true leaves similar to foliage leaves.
An erect tree. It is small to medium sized. It grows 9 m tall. It loses its leaves during the year. The bark is pale grey. The leaves are twice divided. The leaflets are oval and only slightly curved. They are 3-5 cm long. They are unequal on each side. They are shiny green above and paler underneath. The flowers are in loose heads at the ends of the branches. They are yellow or white. They are 5 mm across. The fruit is a flat, thin, leathery pod. It is almost round and 4 cm long by 3 cm wide. It is creamy brown. The seed do not have a fleshy layer around them.
