Discusión taxonómica

(In relation to the synonym Polypodium remotum) Mexican specimens are not as strongly dimorphic as those from Central and South America. Smith (1981) reported that at least some specimens occurred on wet rocks adjacent to and even within streams, as opposed to the species’ usual epiphytic habitat. Smith (1981) also reported that at least occasionally the spores of this species germinate while still inside the sporangia, and thus the sori may appear green.
Polypodium remotum belongs to the P. plebeium group having black-centered rhizome scales with broad tan margins.A
