Shrub or tree to 4 m high. Branchlets slender, with indumentum of sparse to dense ± spreading normally crisped or shallowly curved hairs. Phyllodes crowded, sometimes subverticillate, on short stem-projections, ascending to erect, linear-oblanceolate to narrowly oblong-elliptic, flat, 5–12 (–15) mm long, 1–2 mm wide, l: w ratio = 4–10, obliquely and excentrically mucronulate with the mucro often ± incurved, often acute, green, glabrous or with scattered ± spreading short hairs, often finely longitudinally wrinkled when dry; midrib absent or obscure; gland small, 0.5–2 mm above pulvinus. Inflorescences simple, 1 per axil; peduncles (6–) 8–20 mm long, c. 0.2 (–0.3) mm wide, glabrous or indumentum similar to branchlets, ebracteate at base; heads globular, normally 20–25-flowered, bright yellow. Flowers 5-merous; sepals ¼–½-united, sometimes free; petals normally 1.3–1.5 mm long. Pods normally to 6 (–7.5) cm long, 10–15 (–20) mm wide, firmly chartaceous, pruinose, glabrous.
