The Southeast Asian genus Melanolepis comprises two species, the very variable and widespread M. multiglandulosa (Reinw. ex Blume) Rchb. f. & Zoll. (from Taiwan and the Ryukyu Islands throughout Malesia up to Papua New Guinea and the Bismarck Archipelago) and M. vitifolia (Kuntze) Gagnep., endemic in Cambodia. The two species differ in dentation, incision, and hairiness of the leaves.
