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.
APC Comment:Hybrids are known between D. revoluta var. revoluta and D. longifolia var. longifolia (Henderson, 1987). Ross & Walsh, Census Vasc. Pl. Victoria 15 (2003) suggested that Vic populations at least should be treated as D. laevis, distinct from D. longifolia s.str. which is based on Qld plants. This suggestion has not yet been taken up elsewhere.
