Bean, Muelleria 33:75–83 (2015) argues that this species should be regarded as native, in contrast to the conventional view, in Australia. Its somewhat restricted occurrence in Victoria and the very early date of its first collection in Australia (1804) provide evidence for this view. A related species, Argentina anserinoides (Raoul) Holub, is endemic in New Zealand.
