This segregate genus from Ophioglossum has a single, tropical species characterized by palmately divided leaves bearing usually 6–8 fertile spikes ( Bower 1911, Gómez 1976). It is closely related to the Asian genus Ophioderma (Blume) Endl. , which is also epiphytic but has simple leaves; these two genera have sometimes been treated as congeners ( Hauk et al. 2003).
