It has a disjunct distribution in the eastern Wheatbelt and western parts of the Goldfields-Esperance regions of Western Australia from between Kondinin in the west and Norseman in the east where it is found on flats and on low rocky rises growing in clay-loam soils and is often part of mallee scrub or open Eucalyptus woodland communities. The bulk of the population is found from around 100 km (62 mi) north of Norseman extending south to Frank Hann National Park.
