Distribution

Known only from the type locality and another specimen purported to have been collected from Albany, south-western W.A.

Description

Shrub 0.15–0.5 m high. Branchlets densely villous; indumentum sparser with age. Stipules persistent, linear to linear-triangular, 1–1.5 mm long. Phyllodes frequently slightly curved, ±trigonous in section, 5–9 mm long, 1–2 mm wide, obtuse but with a short distinct mucro, thick, sparsely hairy on margins and abaxial nerves, sometimes densely hairy around pulvinus, 4-nerved in all; central nerve slightly raised on upper surface but strongly raised (when dry) on lower surface; gland absent or c. 1 mm above pulvinus, obscure. Inflorescences simple, crowded at ends of branchlets; peduncles 3–4 mm long, glabrous; basal bract as long or longer than peduncle, long-rostriform, villous; heads globular, 3–4 mm diam., 9- or 10-flowered. Flowers 5-merous; calyx 2/3-united; lobes triangular; petals glabrous. Pods not seen.

Habitat

Grew on rocky slopes in dense shrubland.

Specimens

W.A.: Albany, A.Meebold 11607 (M, PERTH).

Notes

Related to species of the ‘A. sulcata group’, fide R.S.Cowan & B.R.Maslin, Nuytsia 9: 69 (1993), and perhaps closest to A. brachyphylla which has 6–8-nerved, compressed phyllodes and the sepals only shortly united basally.

Conservation

Gazetted a presumed extinct species in W.A.
