Acacia mackeyana is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to south western Australia.
The dense pungent shrub typically grows to a height of 0.5 to 1.7 metres (2 to 6 ft) [1] and has a domed or obconic habit with hairy branchlets that have persistent thick, black and triangular stipules which are less than 1 mm (0.039 in) in length. Like most species of Acacia it has phyllodes rather than true leaves. The ascending to erect, rigid, glabrous and evergreen phyllodes are recurved or straight with a length of 0.7 to 3 cm (0.28 to 1.18 in) in length and 1 to 2 mm (0.039 to 0.079 in) wide and sharply pungent and have 20 closely parallel nerves. [2] It blooms from June to August and produces yellow flowers. [1]
It is native to an area in the Mid West, Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia where it is commonly situated on rocky rises, breakaways, and undulating sandplain growing in sandy, loamy or loam-clay soils often over and around laterite or granite. [1] The bulk of the population is found between Coorow in the north west down to around Corrigin, Western Australia and Moorine Rock in the south east with outlying populations found near Mullewa, Ongerup, Ravensthorpe and the Frank Hann National Park.
