Acacia gemina is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to an area of south western Australia.

Description

The erect open shrub or tree typically grows to a height of 0.4 to 1.2 metres (1 to 4 ft)[1] and has a multi-branched spreading habit with hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, patent to inclined phyllodes have a narrowly oblong to oblong-oblanceolate shape and are straight or slightly recurved. The leathery and moslt glabrous phyllodes have a length of 10 to 25 mm (0.39 to 0.98 in) and a width of 3 to 6 mm (0.12 to 0.24 in) and have three distant prominent nerves on each face.[2]
Distribution

It is native to an area in the Peel and Wheatbelt region of Western Australia where it is commonly situated on scree slopes and along gullies and creeks growing in gravelly soils often containing laterite and in areas composed of sandstone.[1] The shrub has a distribution from around Brookton in the Boyagin Rock Reserve in the north down to around the Saddleback Timber Reserve close to Boddington in the south a couple of outlying populations, one near Hyden and the other around Narrogin where it is found as a part of low woodland communities where it is associated with Eucalyptus drummondii or open heathland communities often dominated by Dryandra carduacea.[2]
