Synonymy: A. brachystachya auct. non Benth., Fl.Austral. 2:403 (1864), nomen dubium. Racosperrnum aneurum.(F Muell. ex Benth.)Pedley, Austrobaileya 2:344 (1987)

Common name: mulga

Phyllodes terete to narrow linear 1.5-10 cm long, 0.5-2 mm wide, silvery hairy, soon resinous.

Inflorescence oblong, 1-2 cm long; peduncle 5-8 mm long, with simple and glandular hairs.

Legume 1.5-2.5 cm long, 6-8 mm wide, papery, rimmed but not winged, almost glabrous, without resin, dull brown. Seeds relatively small, 4~ x 3-4 mm, oval, glossy brown. Funicle expanded into terminal aril.

Related taxa: The group of species related to Mulga has recently been examined by Randell (1992). She reduces the name A. brachystachya to a synonym of Mulga largely on the basis that the type specimen is inadequate and that it is not possible to decide whether it is what she considers to be A. cibaria or A. aneura var. stenocarpa and is thus a confused name. The group of species remains difficult to separate in the absence of mature pods and the following should also be checked A. ramulosa, A. cyperophylla, A. cibaria, A. minyura, A. ayersiana and A. paraneura.

Taxonomic notes: The record of this variety in South Australia is based on a photo taken in the far north west of the State and on personal observation. However no specimens supporting its presence have been located in the State Herbarium.

Cultivation: Not known in cultivation.
