Acacia warramaba Maslin, Nuytsia 4: 108; 109, fig. 2 & 112, fig. 3 (1982)
Rounded or obconic shrub to 3.5 m high. Branchlets glabrous. Phyllodes ascending to erect, linear to narrowly elliptic or narrowly oblanceolate, straight, 4–8 (- 10) cm long, 3–7 (- 10) mm wide, acute to acuminate with recurved to uncinate and innocuous tip, glabrous, with numerous, close, parallel, non-anastomosing nerves with the central one slightly more pronounced than the rest. Inflorescences 2 (- 4)-headed racemes; raceme axes 2–5 mm long and terminated by a resinous vegetative bud; peduncles 4–8 mm long, appressed-puberulous or glabrous; heads globular, 3.5–4 mm diam., 45-flowered, light golden. Flowers 5-merous; sepals free. Pods narrowly oblong, not constricted between seeds and slightly raised over them, to 7 cm long, 5–8 mm wide, chartaceous, red-brown, glabrous to subglabrous. Seeds transverse to oblique, elliptic or oblong-elliptic, 3–4.5 mm long, shiny, brown to blackish; aril clavate.
Occurs from Marvel Loch and near Boulder SE to Peak Charles and Fraser Ra., southern W.A. Grows in low hilly country in loam or clay, often over greenstone or granite, mostly in mallee woodland or shrubland.
Seems related to A. redolens which has resin-ribbed, hoary branchlets, phyllodes with the nerves more widely spaced and narrower pods.
