Spreading sprawling shrub 0.2–1 m tall. Branchlets pilose, ±hirsute, pubescent or glabrous, with hairs rarely crisped. Stipules 2–7 mm long, setaceous, spinescent or only indurate bases subspiny, straight or recurved. Phyllodes asymmetrically ovate to narrowly ovate, elliptic to narrowly elliptic or narrowly oblong-elliptic, 5–25 mm long, 3–14 mm wide, undulate, pungent by a slender cusp, with indumentum as on branchlets, usually 1-nerved; lateral nerves obscure. Inflorescences simple, 1 or 2 per axil; peduncles 5–25 mm long, hirtellous to puberulous or glabrous; heads globular to slightly obloid, 5–8 mm diam., 40–100-flowered, golden; bracteoles normally narrow and long-acuminate. Flowers 5-merous; sepals variably united for ¼–⅔ their length, with lobes linear to triangular; petals 1-nerved. Pods narrowly oblong, often curved, to 6 cm long, 4–5 mm wide, undulate, densely pilose to villous. Seeds longitudinal to oblique, oblong to widely ovate or elliptic, 3 mm long, light grey or brown, often mottled; aril subterminal.
