  • The species typically occurs in open shrubland communities and is often associated with stunted canopy species in the upper stratum. Commonly associated with Eucalyptus campanulata and E. notabilis in the upper stratum, Plectranthus graveolens, Acacia falciformis and Ozothamnus diosmifolius in the mid storey stratum, and Themeda triandra, Xanthorrhoea malacophylla and Stylidium laricifolium in the understorey.
