Acacia patagiata R.S.Cowan & Maslin, Nuytsia 7: 216; 211, fig. 1I–J (1990)

Rounded, spreading shrub 0.5–2.5 m high. Branchlets glabrous or glabrescent. Phyllodes ascending to erect, elliptic to oblong-oblanceolate, mostly shallowly to strongly incurved, 2.5–5.5 cm long, 3–8 mm wide, acute to obtuse, mucronate, innocuous to coarsely pungent, rigid-coriaceous, glaucous, glabrous, with numerous, fine, parallel venules of equal prominence or more commonly the central nerve more evident than the rest, the strong marginal nerves yellow; glands 2 or 3 along adaxial margin. Inflorescences simple, 2 per axil; peduncles mostly 3–6 mm long, typically glabrous; heads globular, golden, 4–5 mm diam., 16–24-flowered. Flowers 4-merous; sepals 1/4–3/4-united. Pods pendent, linear, curved, to 9.5 cm long, 2–3.5 mm wide, crustaceous, glabrous. Seeds longitudinal, oblong, 3.5–4.5 mm long, glossy, dark brown to black; aril apical.

Common throughout its range from Pingrup E to near Mt Ney in south-western W.A. Grows in sandy to clayey soils along salt creeks or rivers and at margins of salt lakes and salt pans.

Closely resembling A. lineolata subsp. multilineata and to a lesser extent A. unguicula but it is very distinct by virtue of its tetramerous flowers and by features of the phyllode venation: the main nerves are continuous from base to apex but hardly more distinct than the irregular, crooked, fine lines of the numerous secondary nerves; in addition the marginal nerves are strongly developed and yellow. Also similar to A. mimica .
