Acacia formidabilis is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to south western Australia.
The diffuse pungent shrub typically grows to a height of 0.2 to 0.6 metres (1 to 2 ft) [1] with hairy branchlets that have persistent recurved spinoose stipules with a length of 1.5 to 3 mm (0.059 to 0.118 in). Like most species of Acacia it has phyllodess rather than true leaves. The evergreen patent to ascending phyllodes have an inequilaterally narrowly elliptic to oblong-lanceolate shape and can be shallowly recurved. The pale green to grey-green, pungent, leathery, glabrous and rigid phyllodes have a length of 1.3 to 2.5 cm (0.51 to 0.98 in) and a width of 2.5 to 4 mm (0.098 to 0.157 in) and have many fine parallel nerves. [2] It blooms from August to September and produces yellow flowers. [1]
It is native to an area in the Wheatbelt and Goldfields regions of Western Australia where it is commonly found in undulating plains and hillsides growing in sandy soils. [1] The shrub has a scattered distribution from around Paynes Find and Perenjori in the north down to around Southern Cross in the south where it is usually a part of tall open shrubland communities.
