Discusión taxonómica
(In relation to the synonym) Polypodium muenchii is distinct in its pinnatifid blades, lustrous brown rhizome scales, and occurrence at high elevations. Young sori with roundish scales caused Smith (1981) and Mickel and Beitel (1988) to place it in Pleopeltis, but the soral scales in fact are not peltate but cordate-based. The distinctness of this species caused Gómez (1985) to erect the genus Microphlebodium. Recently, a simple-bladed species, P. microgrammoides (which see), was discovered in this group.A
