Three-nerved Wattle , Three-veined Wattle , Green Wattle , Hindmarsh Wattle
Rounded, fragrant shrub or tree 1–5 m high, sometimes prostrate. Branchlets resin-ribbed at extremities, hoary puberulous. Phyllodes oblanceolate to oblong-oblanceolate, straight to slightly incurved, 3–7 cm long, 4–11 mm wide, obtuse with minute, callose apiculum, dark green, glabrous, 3–7-nerved per face with 3 nerves more prominent than the rest (when multinerved), the nerves resinous and impressed in crests of low ridges; anastomoses absent or few between the nerves; gland at distal end of pulvinus. Inflorescences 3–8-headed racemes; raceme axes 5–7 mm long, resinous hoary; peduncles 3–5 mm long, resinous hoary; heads globular, 3.5–4.5 mm diam., c. 25-flowered, light to dark golden. Flowers 5-merous; sepals free. Pods linear, raised over and constricted between seeds, straight to slightly curved, to 6 cm long, 2–4 mm wide, chartaceous, glabrous to very sparsely appressed-hairy. Seeds longitudinal, oblong, 4 mm long, glossy, black; funicle/aril apical.
Disjunct, occurring across the central and south-western slopes and plains of N.S.W. from Gilgandra SW to Berrigan; also in western Vic. from Wyperfeld S to Dimboola, extending to near Lucindale, S.A. (collections from further west in S.A. probably represent naturalized occurrences). Sometimes near inland water, growing in red earths and clay, often in mallee communities.
Among the syntypes of this taxon in the invalid publication by F.J.H. von Mueller, Pl. Victoria 2: 25 (1863), is a collection (duplicate at K) by Dallachy from the Wimmera; when the species was validly published, the Dallachy specimen was not cited.
Very closely related to A. redolens of south-western W.A.
