Small tree with spreading crown to 10 m high and 22 cm d.b.h. Branchlets angular, glabrous or scurfy. Phyllodes half-elliptic, basiscopic margin straight to scarcely curved, acroscopic margin curved, often undulate and indented at the junction of the prominent longitudinal veins with the margin, acute, 5-12 by 1.4-3.2 cm, 2.5-4.5 times as long as wide, grey, major veins and margins yellowish; pulvinus 0.5-0.9 cm, with a gland at the top, circular, not swollen, c. 0.5 mm in diameter, with a yellow margin around the orifice; prominent longitudinal veins 4 and about the same number of less prominent longitudinal ones, all concurrent with the basiscopic margin at the base, with numerous tertiary finely reticulate veins in between. Spikes rather sparsiflorous, 1.5-2 by 0.25 cm, on glabrous peduncles 0.3-0.5 cm long, solitary or paired in the axils of the distal phyllodes. Flowers pentamerous. Calyx broadly cylindrical, glabrous, sinuate, scarcely lobed, 0.4-0.5 mm. Corolla deeply lobed, 1.2-1.5 mm. Stamens c. 2.5 mm. Ovary sessile and tomentose.
