Acacia ingrata Benth., Fl. Austral . 2: 331 (1864)
Much-branched, diffuse shrub normally 0.2–0.5 m high. Bark light grey. Branchlets hirsutellous or glabrous. Stipule bases commonly persisting as tooth-like projections. Phyllodes subdistant, sessile, patent to slightly reflexed, narrowly triangular to linear or narrowly oblong, 6.5–20 mm long, 1–2 mm wide, pungent, green, glabrous or subglabrous; midrib not prominent; gland basal. Inflorescences mostly 1- or 2-headed racemes; raceme axes 1–2 mm long, often growing out at anthesis; peduncles 3–7 mm long, glabrous or subglabrous; heads sparse, globular, 5–7-flowered, cream to white. Flowers 5-merous; sepals 1/3–1/2-united, c. 1/4 length of petals; petals nerveless. Pods submoniliform, to 5 cm long, 4–5.5 mm wide, thinly coriaceous, finely longitudinally reticulate, glabrous, dehiscing along adaxial suture. Seeds longitudinal, elliptic, 4.5–6 mm long, dull, dark brown; aril conical, terminal.
Occurs from Middle Mt Barren E to the Young R., south-western W.A. Grows in often rocky or lateritic clay or clay loam in Mallee scrub or heath.
Related to A. plautella . The Murchison R., Oldfield specimen ( n.v. ) referred to by G.Bentham in the protologue of A. ingrata is probably A. andrewsii .
