Fallax (D.E.Symon 12311) was the informal phrase The census is maintained in a database by the State name for the now formally published Eremophila fallax Herbarium of South Australia and projected on the Chinnock.

Alternatively name changes changes will be adopted since published opinion is not can occur which do not affect the concept of the species, always accepted by the greater botanical community. or at least not in the context of South Australia.

Aug.DC. Previously treated as G. oppositifolia (L.) A.DC. Incorrect ending for species name and incorrect authorship. Leptosema chambersii F.Muell. Previously treated as L. chambersii F.Muell. subsp. chambersii. Between 1986 and 1993 subspecies rank was used in the census for no apparent reason and this is now corrected. Myriocephalus rhizocephalus (DC.)Benth. Previously as M. rhizocephalus var. rhizocephalus. However M. rhizocephalus var. pluriflorus has been raised to species level and so there is now no need for the autonym. Olearia pimeleoides (DC.)Benth. Lander (2008) raised subsp. incana to species level and so subsp. pimeleoides is no longer recognised. Ptilotus gaudichaudii (Steud.)
