Discusión taxonómica
Anemia intermedia is intermediate between A. brandegeei of Sinaloa and A. clinata Mickel (Panama to Bolivia) in size, the medium brown stipe color, and slightly ascending fertile pinnae. If the three species are distinct, A. intermedia may either represent an intermediate stage in the divergent evolution of the group or be of hybrid origin from the other two species. Quite possibly A. brandegeei is a diminutive form of A. intermedia, and the former has priority.
