Distribution and ecology

Restricted to two known populations, one near Mt Clare, the other near Granite Peak, in south-west WA. 

Found in tingle (Eucalyptus jacksonii and E. guilfoylei) or karri (E. diversicolor) dominated forest adjacent to granite outcrops.


Phylogenetic studies by Garcia & Olmstead (2003) on the Tribe Anthocercideae using two chloroplast DNA regions included this species. The studies indicated that Anthocercis is monophyletic.
