Small, divaricate spreading shrubs 0.5-1 m high; branches slender, spinescent, pruinose but grey reddish-brown as the whitish covering peels and flakes away, sprinkled with short whitish hairs but becoming glabrous when mature, many of the older phyllodes fall away leaving an open twiggy appearance. 

<P>Phyllodes oblong-elliptic, 0.8-2 cm long, 1-2 mm broad, thick, glabrous or sprinkled with hairs, veins longitudinal, 3-5 rather obscure, apex obtuse and with a small gland beneath the short mucro. Stipules paired, acicular small, reddish-brown, caducous on older branches.

<P>Inflorescences simple and axillary solitary or twin; flower-heads globular, yellow, c. 30-flowered; peduncles filiform glabrous 5-10 mm long; flowers 5-merous. Legumes linear, 3-5 cm long, 2-3 mm broad, curved or twisted, raised over the seeds, dark brown, margins thickened, slightly constricted between seeds. Seeds longitudinal in legume; funicle very short and filiform abruptly passing into a thick fleshy oblique aril.
