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.
