Dense spreading multistemmed glabrous shrub 0.5–2 m high. Branchlets angled to flattened at extremities; cuticle often white. Phyllodes patent to erect, narrowly elliptic to ±narrowly oblong or linear, narrowed at both ends, straight to recurved, 4–10 cm long, 4–9 mm wide, acute to subacute, innocuous to ±pungent, subrigid, smooth, greyish green, often glaucous when young; midrib and margins prominent; lateral nerves absent or obscure; gland 0–3 mm above pulvinus. Inflorescences normally 4–7-headed racemes; raceme axes 6–16 mm long, enclosed when young by imbricate brown bracts; peduncles 5–11 mm long, slender; heads globular, 20–30-flowered, golden; bracteoles absent. Flowers 5-merous; sepals free. Pods shallowly curved to openly 1 1/2-coiled, to 8 cm long, 5–8 mm wide, chartaceous. Seeds longitudinal, oblong to elliptic or ovate, 3–5 mm long, dull, dark brown to black, exarillate. Fig. 43A–E.

Occurs from Kanandah Stn, Nullabor Plain, W to near Ongerup and Canna, W.A. There is also a recent collection from near Maralinga, S.A. Often locally common. Grows in sand, loam or clay, in woodland or shrubland, sometimes on laterite or granite rocks. Map 232.

W.A.: 211 km E of Kalgoorlie near Zanthus, T.E.H.Aplin 5709 & M.E.Trudgen (CANB, PERTH); near Kalannie on Dalwallinu Rd, A.M.Ashby 4244 (PERTH); 24 km S of Lake Grace, J.Goodwin 20 (PERTH); 3.2 km N of Moora on Geraldton Hwy, B.R.Maslin 1403 (K, NSW, PERTH); 15 km SSW of Queen Victoria Rocks, K.Newbey 5683 (CANB, PERTH). S.A.: 26 km ESE of Maralinga, L.D.Williams 9618 (AD).

A member of the ‘A. prainii group’ and close to A. prainii itself which has narrower, more pungent phyllodes; also, the branchlet ribs and phyllode margins and midrib are sometimes viscid. A putative hybrid between the two species occurs at Burracoppin (i.e. M.L.Cody s.n. , PERTH00346411). Until recently A. anthochaera was regarded as a long phyllode variant of A. hemiteles ; these two species also appear to sometimes hybridise.
