Acacia glaucissima Maslin, Nuytsia 12: 350 (1999)
Spreading, glabrous shrub 0.6–1.5 m high. Branchlets terete, ribbed. Stipules 3–4 mm long, brittle, at least thickened bases persistent. Phyllodes slightly inequilateral, narrowly elliptic to oblong-elliptic or oblanceolate, sometimes obovate or elliptic, undulate or twisted, 2–4 cm long, 5–15 mm wide, acute to obtuse, with coarsely to sharply pungent mucro, thick-coriaceous, smooth, very glaucous; midrib and marginal nerves prominent, yellow or greenish yellow; gland mostly 3–7 mm above pulvinus. Inflorescences 2-headed racemes; raceme axes 1–2 mm long; peduncles 10–20 mm long; heads globular, 5–6 mm diam., 20–35-flowered, golden. Flowers 5-merous; sepals free. Pods irregularly twisted to loosely coiled, terete, to 6.5 cm long, 2–3 mm wide, thinly coriaceous to slightly crustaceous, black. Seeds longitudinal, oblong, 3 mm long, subnitid, dark brown, sometimes obscurely mottled; aril yellow, conical to galeiform.
Occurs from near Mt Madden (Mt Madden is c. 40 km NNW of Ravensthorpe) E to near Mt Heywood (Mt Heywood is c. 85 km NE of Esperance), but mainly occurs in the Salmon Gums (c. 100 km N of Esperance) S to Grass Patch (c. 70 km N of Esperance) and E to the Mt Heywood area, south-western W.A. Grows in sand and on greyish clay flats in mallee woodland.
Related to A. merrallii which has usually puberulous branchlets, caducous stipules and shorter, less glaucous phyllodes. Superficially similar to A. dermatophylla which has longer stipules, peduncles surrounded at base by a tuft of hairs, hard-bony, narrowly oblong, wider pods and obliquely oriented, larger seeds. Also allied to A. acoma .
