Shrub or tree 3–7 m high, often gnarled, bushy, main branches often rather contorted and widely spreading. Branchlets glabrous or sparingly appressed-puberulous. Phyllodes ascending, elliptic or ligulate, tapering to acute or acuminate apex and long-attenuate base, straight to slightly curved, 5–12.5 cm long, 3.5–16 mm wide, rigid, ±glaucous, sericeous, glabrescent, with numerous very obscure closely parallel nerves; central nerve sometimes slightly raised. Inflorescences rudimentary 1- or 2-headed racemes with axes c. 0.2 mm long, often growing out; peduncles 7.5–15 mm long, ±appressed-puberulous; spikes 2.5–5.5 cm long, 5–7 mm diam., loosely flowered, light golden; receptacle appressed-hairy. Flowers mostly 5-merous; sepals 1/4–1/3 length of petals, united, often golden-puberulous. Pods pendent, linear, raised over and sometimes ±constricted between seeds, straight to slightly curved, 8–20 cm long, 7–18 mm wide, crustaceous-woody, irregularly coarsely reticulate, glabrous, shining. Seeds longitudinal, broadly elliptic, 6–10 mm long, peripherally crested, dull, brown; aril/funicle fleshy. Fig. 62G–I.
W.A., widespread across the Pilbara from Shark Bay NE to near Roebourne and Roy Hill, with one collection from near Wiluna. Grows on sometimes subsaline clay flats, stony plains and hills, in Acacia shrubland and low woodland, dominating in localised areas. Map 406.
W.A.: just N of Billabong, North West Coastal Hwy, G.Phillips for A.M.Ashby 4828 (AD, MEL, NY, PERTH); Wandagee, Minilya R., C.A.Gardner 6165 (PERTH); c. 15 km S of Roy Hill Stn on Great Northern Hwy, B.R.Maslin 5272 (PERTH); 18.5 km W of Tom Price, B.R.Maslin 5573 (BRI, CANB, NSW, PERTH); Wiluna area, Dec. 1970, J.Morrissey (PERTH).
Superficially similar to the flat phyllode variant of A. intorta ; and to A. eremaea (sect. Plurinerve ). Perhaps related to A. hamersleyensis which is most readily distinguished by its more obvious phyllode nerves, denser spikes, more deeply divided, white-villous calyx and pilose pods.
