DunT, GGr, MuM, Wim. Also SA. Localized in Victoria where known with certainty only from northern outliers of the Grampians, growing in shallow soils on rock ledges under low shrubs.

Plants of similar appearance from heavy clay soils in mallee communities of the Little Desert and Big Desert may be referrable to this species.
