Two subspecies are sometimes recognised based on corolla size, A. gangetica subsp. gangetica and A. gangetica subsp. micrantha (Nees) Ensermu. Material in NSW is similar to the latter subspecies. However, these two subspecies are inadequate to describe the variation in this taxon, and are not recognised here. Pending further study Asystasia gangetica> is best described as a species complex.
