Small, straggly, often spindly and rather loosely-branched shrubs to 1.5 m high with short thin stems that divide into rather long slender etching branches; branchlets reddish-brown, usually pubescent slightly angular but soon becoming almost terete, marked with small raised phyllode bases.

Phyllodes obliquely obovate or orbicular, 5-14 mm long, flat, more or less pubescent (sometimes quite densely hairy), mucronulate, main vein close to the lower margin and somewhat obscure, usually with a few fainter lateral veins; glands small on the upper margin below middle.

Inflorescences simple and axillary solitary or twin; flower-heads globular, bright yellow, c. 10-15-flowered; peduncles slender glabrous usually longer than the phyllodes; flowers 5-merous.

Legumes linear, spirally coiled, 2-4 mm broad, mid to dark brown, glabrous or sometimes sparsely hairy; margins yellowish, vein-like. Seeds longitudinal in legume, obloid; funicle short, thickened into a clavate aril.
