 With over 750 species , Ficus is one of the largest angiosperm genera . Based on morphology , English botanist E. J. H. Corner divided the genus into four subgenera , which was later expanded to six . In this classification , Ficus obliqua was placed in subseries Malvanthereae , series Malvanthereae , section Malvanthera of the subgenus Urostigma . In his reclassification of the Australian Malvanthera , Australian botanist Dale J. Dixon altered the delimitations of the series within the section , but left this species in the series Malvanthereae .
