The Australian Plant Census (APC) is a list of the accepted scientific names for the Australian vascular flora, ferns, gymnosperms, hornworts and liverworts, both native and introduced, and includes synonyms and misapplications for these names. The APC covers all published scientific plant names used in an Australian context in the taxonomic literature, but excludes taxa known only from cultivation in Australia. The taxonomy and nomenclature adopted for the APC are endorsed by the Council of Heads of Australasian Herbaria (CHAH).
Showing Cycas arnhemica
Included in the synonymy of C. angulata by de Laubenfels & Adema (1998). Three subspecies were recognised in this species in Flora of Australia, but are no longer maintained by NT botanists. Others however believe that the species varies regionally and that the subspecies have some validity. Hybrids are recorded between M. arnhemica and M. orientis (NT Census).
