 The species is currently regarded as monotypic. Three varieties of Ficus obliqua were recognised until 2001 — F. obliqua var. petiolaris, F. obliqua var. obliqua, and F. obliqua var. puberula from Western Australia. A revision of the group led to the conclusion that F. obliqua var. petiolaris belonged in the species F. rubiginosa. F. obliqua var. puberula was found to be more distantly related to obliqua than rubiginosa and hence has been reclassified as a separate species, Ficus brachypoda.
