Discusión taxonómica
Elaphoglossum revolutum is closely allied to E. squamipes and E. peltatum, as evidenced by the rhizome habit, scales, and spores. It is distinguished from E. affine, E. tenuifolium, and small specimens of E. guatemalense by the orange, ovatelanceolate rhizome scales and the lack of phyllopodia, and from E. squamipes by the generally more elliptic blades and occurrence at much lower elevations.A
