Small, erect, rigid, prickly, pubescent shrubs 0.5-2 m high, with numerous intricate branches; branchlets striate, covered with erect stiff short white hairs. Phyllodes broadly triangular and humped on upper margin, 4-12 mm long, 3-7 mm broad, flat, rigid, with scattered hairs, one main vein running to the acute pungent point, 2-4 less prominent veins arising from near the base of the main vein.

Inflorescences simple and axillary, solitary; flower-heads slightly elongated golden-yellow, 8-15-flowered, a very obtuse hood-shaped bracteole covering each flower in bud; peduncles short or about as long as phyllodes with a pair of brown basal bracts; flowers 5-merous.

Legumes linear but curved, twisted and spirally coiled usually with 2-4 closely pressed coils (like a Medicago) c. 5 mm broad, dark brown, pubescent. Seeds longitudinal in legume, ovoid; funicle short, soon thickened.into an oblique fleshy aril.
