''Acacia kalgoorliensis'' (R.S.Cowan & Maslin, Nuytsia 10: 215, 1995) also known as '''Kalgoorlie Wattle''' native to Western Australia it has dense, rounded multistemmed shrub 1–3 m high.

Acacia kalgoorliensis (R.S.Cowan & Maslin, Nuytsia 10: 215, 1995) also known as Kalgoorlie Wattle native to Western Australia it has dense, rounded multistemmed shrub 1–3 m high. Branchlets subappressed puberulous, the hairs white with red resin-hairlets intermixed. Phyllodes erect, straight, terete, 3–7 cm long, 1.5 mm diam., tapering into long, hard, dark, straight, sharply pungent tip, rigid, glabrous except pulvinus crispate-sericeous, with numerous slightly raised, closely parallel nerves; stomata evident between the nerves; glands normally 2. Inflorescences simple, 2 per axil; peduncles usually 0.5–1.5 mm long, glabrous or with scattered red resin-hairlets; heads globular to widely ellipsoid, 3–6 mm diam., 15–22-flowered, golden. Flowers 5-merous; sepals free. Pods linear, raised over and constricted between seeds, shallowly curved, to 7.5 cm long, 3 mm wide, chartaceous, glabrous. Seeds longitudinal, narrowly elliptic to oblong-elliptic, 4-4.5 mm long, dull, dark brown; aril terminal.
There are four collections from areas more than 300 km NW of the principal occurrence of A. kalgoorliensis in the general vicinity of Kalgoorlie; these closely resemble the species but have broadly ellipsoid, 30–40-flowered heads on peduncles 2–4 mm long; these have been treated as representing an informal variant of the species.
Geographic distribution
Occurs in the Kalgoorlie and Marvel Loch (c. 200 km WSW of Kalgoorlie) areas with a variant scattered c. 320- 560 km NW of Kalgoorlie (near Wubin and Noongal and Yuinmery Stns), W.A. Grows in rocky loam, clay and clay loam on low hills in eucalypt woodland. The variant grows in sandy clay and loam over calcrete in eucalypt open woodland and Acacia tall shrubland.
