Acacia ligustrina is a shrub or tree belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The spreading shrub or tree typically grows to a height of 1.5to. The branchlets of the plants are covered with more or less straight hairs. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes are often shallowly recurved and have an asymmetrical oblong-elliptic or narrowly elliptic shape. The thinly coriaceous phyllodes are in length and with a non-prominent midrib.[1] It produces yellow flowers from August to October.
It is native to an area in the Mid West and Wheatbelt regions of Western Australia where it is commonly situated on low hills, around salt flats and depressions growing in loamy, clay or sandy clay soils often containing lateritic gravel.
