Stipules spinose, 2.5–5 mm long, straight or shallowly recurved. Phyllodes sessile, patent to ascending, straight or shallowly curved, sometimes slightly kinked at the gland, pentagonal in section, 20–45 mm long, c. 1.5 mm diam., pungent, rigid, thick, green, usually glabrous, 5-nerved; gland 1–5 mm above base, 1–2 mm long. Inflorescences rudimentary 2–4-headed racemes with axes <0.5 mm long; peduncles 3–5 mm long, yellow to light brown, glabrous, often recurved in fruit; heads globular, c. 25–flowered, golden. Flowers 5-merous; sepals 1/2–3/4-united. Pods (mostly immature) linear, to 9 cm long, c. 4.5 mm wide, crustaceous, blackish, usually glabrous. Seeds (immature) longitudinal; aril pileiform.

Scattered from Mt Malcolm in the Fraser Ra. E to Norseman and SE of Peak Charles, south-western W.A. Grows in sand or loam, often near granite rocks or salt lakes, in Eucalyptus woodland or Mallee communities.
