Taxonomic notes: The authors did not cite any specimen for this species, but it was published in an enumeration of plants collected by Mueller in S.Aust. These were forwarded to Sonder, together with a collection by Dr Behr and by C. Stuart (in Tas.), before Mueller left Adelaide for Melbourne. Three sheets of this species in the National Herbarium of Vic. have legends in Mueller's script. One is from the Murray River near "Morundie", collected in Feb. 1847. Another is from the banks of the River Murray near Wood Station, June 1847. The third is placed only as Murray Flats, collected in Feb. 1851, and attributed to Behr. These three specimens may be the only ones ever collected in this State, but they definitely place this species as a part of the flora of South Australia at one time. The most recent collection appears to be one from Lake Charm, north-western Victoria, made in March 1925. This species is thought now to be extinct, but a search for it should be continued.
