Shrub to 3 m high, bushy, rounded or obconic. Branchlets crenulate-resinous ribbed, glabrous. Phyllodes narrowly elliptic to linear-elliptic, (2–) 3–6 cm long, (2–) 3–6 mm wide, with acute brown shallowly recurved tip, coriaceous, glabrous, glaucous when young, ageing green; margins yellowish and resinous (the resin commonly crenulate); central vein more evident than the numerous indistinct closely parallel secondary veins. Inflorescences simple, 1 or 2 per axil; peduncles 1–2 mm long, glabrous except for minute reddish resin-papillae especially when young; heads globular, c. 4 mm diam., 20–25-flowered, golden. Flowers 5‑merous; sepals united into slightly lobed cup. Pods linear, straight to shallowly curved, to 4.5 cm long, 3–4 (–5) mm wide, thinly coriaceous-crustaceous, glabrous, resinous but not viscid. Seeds longitudinal, oblong-ovate, c. 2.5 mm long, subshiny, mottled; funicle/aril yellow.
Grows mostly on rocky outcrops in heavy soils and sandy clay loam, in Eucalyptus wandoo low woodland and in association with Melaleuca uncinata, Allocasuarina campestris and other Acacia spp.
