*EGL, *GipP, *HSF, *MuF, *MuM, *OtP, *Strz, *VVP, *WPro. All States except NT. Origin uncertain. Haworth thought that C. aequilaterus might be native to Australia. Blake (1969) considered the species to be native to the coasts of Chile, however, only C. chilensis Molina is listed in Zuloaga et al. (2008), which Blake treated as a taxonomic synonym of C. aequilaterus. Walsh (1996) gave the origin as South Africa, however the name does not appear in Wisura & Glen (1993), nor in SANBI (online). Planted for control of erosion of sandy and sometimes saline soils near the coast and inland, occasionally escaping, apparently well-established along the coast east of Port Phillip, but precise distribution unclear due to confusion with other species.
