Distribution and Ecology

Australia: West Australia, Warren District (Farjon 1998); this is extreme southwestern Australia. You can create a highly detailed map, and access specimen data, using the "search" function at the Australia Virtual Herbarium.

Occurs in understory of lowland jarrah and karri (Eucalyptus spp.) forests on sandy soils, and spreads mainly by root suckering (Farjon 2010). Based on data from 34 collection localities, it grows at elevations of 120 ±80 m. Within its range, mean annual temperature is 15.6°C, with an average minimum in the coldest month of 7.2°C, and a mean annual precipitation of 1011 mm (Biffin et al. 2011, Table S5). Zone 10 (cold hardiness limit between -1°C and +4.4°C) (Bannister and Neuner 2001).

The IUCN reports that the population status is stable.
