This species has often been treated as Ficus superba var. japonica, but it is quite distinct from F. superba s.str. which does not occur within the Flora area (Berg, in litt.). Chinese material has also been named as F. tenuipes S. Moore, but we follow Corner, who regarded F. tenuipes as a synonym of F. superba s.str. Chinese records of F. wightiana Wallich ex Miquel were based on misidentifications of this species.
