It has a disjunct distribution and is known in two areas that are situated approximately apart in the Flinders Range in South Australia. It is found around Brachina Gorge and Wilpena Pound in the north and around Nectar Brook on the Winninowie Range in the south. It is often situated on rocky ridgetops as a part of mallee communities over spinifex grassland or in Callitris pine communities.[1]
