Taxonomic notes: Although J. Black (1943), Fl. S. Aust., recorded this species for S.Aust, I am very doubtful of its occurring here. All but one of the specimens previously identified as M. mutica have been reidentified as belonging to other species, especially M. drummondii. This latter species becomes almost glabrous when growing in aquatic situations. One sterile specimen collected by Dodd near Morgan on the River Murray in 1894 has exceedingly large leaflets and may be correctly identified as M. mutica.
