Vernacular names

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


The shrub or tree typically grows to a height of 0.6 to 4 metres (2 to 13 ft)[1] and has a dense, rounded or obconic habit with glabrous and slightly angular branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, inclined to erect phyllodes are flat with a linear to narrowly oblanceolate shape and a length of 2 to 8.5 cm (0.79 to 3.35 in) and a width of 0.8 to 6 mm (0.031 to 0.236 in) with many closely parallel indistinct to distinct nerves.[2] It blooms from August to October and produces yellow flowers.[1]

It is most closely related to Acacia lineolata and Acacia inceana which all belong to the Acacia enervia group of wattles.[2] There are two recognised subspecies:

Acacia enervia subsp. enervia
Acacia enervia subsp. explicata[2]


It is native to an area in the Wheatbelt and Goldfields-Esperance regions of Western Australia where it is commonly situated in salt marshes, flats and lakes and rocky hills usually growing in sandy or loamy soils and rarely in clay soils.[1] The distribution of the plant extends from Jibberding in the north west to around Lake Grace and Lake Magenta in the south east out to around Clear Streak Well in the east.[2]
