Acacia dermatophylla Benth., Fl. Austral . 2: 346 (1864)
Open, normally single-stemmed shrub 0.2–0.5 m high. Branchlets glabrous. Stipules persistent, erect, shallowly incurved, 4–8 mm long, sometimes pungent, thick, often yellow. Phyllodes ascending, normally oblanceolate to linear-oblanceolate, 2–5.5 cm long, 4–15 (- 23) mm wide, often slightly undulate, with coarsely pungent, frequently inflexed mucro, very thickly coriaceous, finely wrinkled when dry, glaucous or subglaucous, glabrous; midrib and margins prominent and normally yellowish; gland 6 mm above pulvinus. Inflorescences rudimentary, 2-headed racemes with axes c. 1 mm long; peduncles mostly 5.5–15 mm long, glabrous but with a dense tuft of hairs around base, recurved in fruit; heads globular, 5–7 mm diam., 20–40-flowered, golden. Flowers 5-merous; sepals free. Pods narrowly oblong, not constricted between seeds, biconvex, to 6.5 cm long, 8–10 mm wide, hard and bony, glabrous. Seeds oblique, oblong to broadly elliptic, c. 5 mm long, dull, brown; aril terminal, pileiform.
Occurs in southern near-coastal W.A. from the Fitzgerald R. to near Ponier Rock (c. 65 km SW of Balladonia). The type reported to come from the Murchison R. but this is the only specimen from north of Perth and may well be an error, for Oldfield collected both north and south of Perth. Grows in sand, sandy loam or sandy clay or rocky clay, sometimes near salt lakes or salt flats, in tall mallee and heath.
Allied to A. pachyphylla and A. glaucissima .
