About

Acacia caesaneura, commonly known as western blue mulga, is a species of flowering plant in the family Fabaceae and is endemic to inland Western Australia. It is a multi-stemmed shrub with a silvery bluish grey crown, mostly narrowly oblong to elliptic phyllodes, cylindrical spikes of golden yellow flowers, and winged, firmly papery pods.

Western blue mulga is found on plains or in undulating country in the Avon Wheatbelt, Coolgardie, Gascoyne, Great Victoria Desert, Murchison, Nullarbor and Yalgoo bioregions of inland Western Australia where it grows on red-brown sandy loam to clay soils, sometimes over hardpan in shrubland or woodland communities. The bulk of the population is found from around Yalgoo in the west to around Meekatharra in the north down to around Kalgoorlie in the south extending to around the northern edge of the Nullarbor Plain in the east.
