The S.Aust. plants rarely form mats. In the NT and possibly extending as far as India occurs a more luxuriant form forming dense mats in water or on wet margins of rockholes; it has a subcylindrical calyx 1-2 mm long and longer leaves to 15 mm long, with broader blades. It has not been collected in S.Aust.
