• Text: "The type of the name (Carr 1872) is clearly (from its characters and locality) a hybrid between C. latifolia and C. novoguinensis. ... Specimens cited as E. tokwa by [Carr & Carr (1987)] from various parts of mainland Australia, excluding northern Cape York Peninsula, belong to several other species in series Dichromophloiae subseries Latifoliosae."
