Vernacular names

Acacia concolorans is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to Western Australia.


The intricate and pungent shrub typically grows to a height of 0.1 to 0.5 metres (0.3 to 1.6 ft).[1] It has green and scabridulous branchlets with yellow ribs and 2 mm (0.079 in) long straight stipules. The pungent, green and oblong to narrowly oblong shaped phyllodes are flat and thick with a length of 4 to 10 mm (0.16 to 0.39 in) and a width of 1.5 to 2 mm (0.059 to 0.079 in).[2] It blooms from July to August and produces yellow flowers.[1] The rudimentary inflorescences occur in groups of two per raceme, the small spherical flower-heads contain seven to eight golden flowers. The narrowly oblong seed pods that form after flowering are curved and have a length of around 5 cm (2.0 in) and a width of 4 to 5 mm (0.16 to 0.20 in). the pods contain irregularly ovate-elliptic shiny dark brown seeds.[2]

The species was first formally described by the botanist Bruce Maslin in 1999 as part of the work Acacia miscellany 16. The taxonomy of fifty-five species of Acacia, primarily Western Australian, in section Phyllodineae (Leguminosae: Mimosoideae) as published in the journal Nuytsia. It was reclassified as Racosperma concolorans by Leslie Pedley in 2003 and transferred back to the genus Acacia in 2006.[3] It is closely related to Acacia inamabilis which has larger phyllodes and larger flower-heads containing many more flowers.[2]

It is native to an area of the Wheatbelt and the Goldfields-Esperance regions of Western Australia between Kondinin and Yilgarn where it is found on lateritic flats and hills growing in red to brown loam-clay soils[1] as a part of open Eucalyptus woodland or mallee shrubland communities.[2]
