Looks like a "different" species of Indigofera, not the common "australis" species. First time I have seen this species in this location (Mt Majura). Small pinkish Pea flower in distinctive clusters "raceme" ?
Hi Max, well spotted. It is less common compared to Indigofera australis. It was included in the list of rare plants when we began surveys years ago. It is heavily grazed as is the I. australis.
