Confined to the Caiguna–Eyre–Cocklebiddy area of W.A., except for one collection from near Israelite Bay, c. 200 km due SW of Caiguna.


Spreading, domed or ±straggly shrub 0.5–1.5 m high. Branchlets glabrous, roughened by bark breaking into irregular or rectangular flakes. Phyllodes ascending to erect, obovate to oblanceolate, flat, 5–10 mm long, 1–2.5 mm wide, rounded-obtuse, thick and subfleshy, drying rugulose, glabrous; abaxial margin 1-nerved; other nerves obscure; gland inconspicuous, 2–4.5 mm above base. Inflorescences simple, 1 or 2 per axil; peduncles 4–6 (–8) mm long, glabrous; heads globular, 3–3.5 mm diam., 9–11-flowered, light golden. Flowers 5-merous; sepals free, broadly spathulate. Pods (dehisced valves) linear, not or slightly constricted between seeds, to 4 cm long, 2.5–3.5 mm wide, chartaceous, dark red-brown, glabrous. Seeds (immature) longitudinal.


Grows in calcareous sand, loamy sand or clay loam over limestone pavement at shallow depth, in open shrub or tree mallee.


W.A.: 9 km S of Cocklebiddy, A.S.George 11838 (AD, BRI, PERTH); 36 km SE of Mt Ragged [near Israelite Bay], A.S.George 16027 (PERTH); 12 km NNW of Eyre, S.D.Hopper 3017 (K, MEL, PERTH).
