CVU, Gold, GGr, LoM, MuM, MSB, RobP, VRiv, Wim. WA, NT, SA, NSW. Relatively rare in Victoria where known from scattered sites in the west and north-west (Little Desert, Black Range near Stawell, Wedderburn, Gunbower, Ouyen, Mildura areas), and occurring in mallee and woodland formations. Victorian specimens, although conforming to the description provided by Vickery el al. (1986), differ from the type (from WA) and Bentham's (1878) description which emphasizes the rigid, smooth, shining leaf-sheaths as well as the hispid blades.
