In some classifications, Gevuinia is recognised with three species: one endemic to Australia (Gevuina bleasdalei), another to New Guinea (Gevuina papuana), and one species in both Chile and Argentina (Gevuina avellana). Other taxonomic reports place the Australian and New Guinea species in the genus Bleasdalea[4] or in the Fijian endemic genus Turrillia, and leave Gevuina with only Gevuina avellana.[5] The Flora of Australia retains these 2 species in Gevuinia,[6] but the most recent classification places the Australian and New Guinea species as Bleasdalea bleasdalei and B. papuana[7]
