Extends from the Gawler Ra. and southern Eyre Peninsula and Yorke Peninsula to Arkaba Stn in the Flinders Ra. and near the Murray R., S.A.; also near Nathalia and Meringur, Vic., and near Menindee and Broken Hill, N.S.W.


Bushy spreading shrub to 3 m high. Branchlets dark red-brown, glabrous, not pruinose. Phyllodes narrowly elliptic to oblanceolate or narrowly oblanceolate, (5–) 6–13 (–15) cm long, (6–) 8–25 mm wide, normally obtuse, coriaceous, grey-green to glaucous, glabrous; midrib and marginal nerves prominent; lateral nerves obscure; gland normally 0–3 mm above pulvinus; pulvinus 2–6 mm long. Inflorescences mostly racemose; raceme axes 2–7 cm long, robust, glabrous; peduncles 2–6 mm long, rather stout, glabrous; heads globular, 27–36-flowered, bright golden; bracteole laminae evident in buds, dark brown to black, white-fimbriolate. Flowers 5‑merous; sepals at least c. 3/4-united. Pods stipitate, narrowly oblong, raised on opposite sides over alternate seeds, to 7 cm long, 8–14 mm wide, firmly chartaceous to slightly coriaceous, glabrous. Seeds transverse, oblong-elliptic, 4–7 mm long; funicle encircling seed, dark red-brown; aril clavate.


Grows in sand or rocky sites in low woodland or open scrub.


S.A.: Gawler Ra., Mt Partridge, c. 168 km W of Port Augusta, A.E.Orchard 989 (AD); Wharminda Soak (Wharminda is c. 90 km NNE of Port Lincoln), 10 June 1965, J.B.Cleland s.n. (AD). N.S.W.: Byrnedale Stn, near Menindee, 21 Nov. 1947, E.F.Constable s.n. (NSW). Vic.: N bank of Broken Ck, 9.5 km WNW of Nathalia, N.H.Scarlett 82-89 (MEL).


A member of the ‘Acacia microbotrya group’, related to A. anceps which is distinguished by its non-racemose inflorescences, peduncles 1–2.5 cm, heads 50–130-flowered, and crustaceous to woody pods. Putative hybrids occur between these two species on Eyre Penin., S.A., fide B.R.Maslin & D.J.E.Whibley, Nuytsia 6: 26 (1987). Also related to A. toondulya with which it putatively hybridizes; in the past A. notabilis had sometimes been confused with A. alcockii.

The N.S.W. specimen cited under A. notabilis by G.Bentham, Fl. Austral. 2: 365 (1864) is A. beckleri.
