Resinous shrub to 2 m high. Branchlets finely ribbed below insertion of phyllodes; indumentum mostly of short scattered glandular hairs. Phyllodes crowded, sometimes subverticillate, erect, straight but slightly recurved at apex, probably subterete when fresh, ± depressed-triquetrous when dry, 6–18 mm long, c. 0.4 mm wide, excentrically mucronulate, with two indistinct longitudinally grooves when dry, asperulous-tuberculate; veins not evident; gland minute, near middle of phyllode, often absent. Inflorescences simple, 1 per axil; peduncles mostly 6–10 mm long, asperulous-tuberculate; heads globular, c. 30-flowered, bright yellow, viscid. Flowers 5-merous; sepals united to about the middle. Pods narrowly oblong, to 4 cm long, 3–4 mm wide, with prominent raised cartilaginous excrescences on valves. Seeds longitudinal, oblong, c. 4 mm long; aril clavate.
Grows in lateritic soil with grey sand or clayey silt with ironstone gravel, in gently undulating country, often on stony ridges, in eucalypt woodland and open forest.
