Acacia maxwellii is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The low domed shrub typically grows to a height of 0.1to. It has hairy branchlets with subpersistent long stipules. Like most species of Acacia it has phyllodes rather than true leaves. The thick, glabrous and evergreen phyllodes are erect with a linear shape that is straight to shallowly curved. The phyllodes have a length of and a width of and an impressed midrib. It blooms from September to October and produces yellow-cream flowers.
It is native to an area along the south coast in the Great Southern and Goldfields-Esperance regions of Western Australia where it is commonly situated on flats, undulating plains and along watercourses growing in sandy, sandy clay, loamy or gravelly soils. The range of the plant extends from around the Stirling Range in the north west to around Israelite Bay where it is usually a part of shrub mallee and mallee heath communities.[1]
