Australian Plant Name Index (APNI)
The Australian Plant Name Index (APNI) is a tool for the botanical community that deals with plant names and their usage in the scientific literature, whether as a current name or synonym. APNI does not recommend any particular taxonomy or nomenclature. For a listing of currently accepted scientific names for the Australian vascular flora, please use the Australian Plant Census (APC) link above.
Comment:Combination is validly made by indirect reference to the basionym. Gardner states in the preface, p. ii, that synonyms refer to the name as used by Bentham in Fl. Austral. Gardner includes Cyanostegia bunnyana F.Muell. as a synonym, and Bentham, Fl. Austral. 5: 54 includes Bunnya cyanocalyx F.Muell. as a synonym of Cyanostegia bunnyana F.Muell.
