Biology: A very variable species that has sometimes been treated as a variant of S. maritima (L.)Dumort., a polymorphic Northern Hemisphere annual. Populations from near the Murray River in S. Aust. and neighbouring N.S.W. and Vic. correspond closely to S. maritima and may represent an introduction of that species.
