DunT, GGr, LoM, MuM, RobP, Wim. Also WA, SA, Tas. (Flinders Is.). Grows usually in sandy or gravelly clay soils in the west and northwest of the state but rather uncommon, often occurring with C. colorata and/or C. sieberiana.
Characterized by its star-shaped fruit produced by the reclining follicles that are held in place by the incurved calyx-lobes. Superficially similar fruit occur in some forms of C. sieberiana, a species distinguished by its smooth follicles, which are shorter than the petals and opened to the base.
