Living bark strong and fibrous when stripped.
Leaves phyllodineous. Leaf blades falcate, about 6-10 x 0.4-1.1 cm. Venation longitudinally parallel with about 3-7 veins more prominent than the rest. Petioles about 0.3-0.5 cm long. A small but conspicuous gland usually visible at the junction of the leaf blade and the petiole.
Spikes about 3-4 cm long, solitary or paired, produced in the leaf axils. Flowers yellow, about 1 mm diam, sparsely arranged on the spikes. Calyx and corolla glabrous. Stamens numerous. Anther filaments about 1 mm long. Ovary with white hairs or glandular projections towards the apex, style about 1.5 mm long.
Cotyledons elliptic, about 7 x 4 mm, base sagittate or hastate. No venation visible. First leaf pinnate with 6 leaflets. Second leaf bipinnate with 8 leaflets. At the tenth leaf stage: 'leaf' falcate or elliptic, apex abruptly narrowed into a mucro, base attenuate, midrib raised on both surfaces. Venation longitudinal with 2 or 3 veins slightly thinner than the midrib extending from the base almost to the apex. A single flat gland usually visible on the upper margin of the leaf blade just above its junction with the petiole.
