Discusión taxonómica
This species was treated as a synonym of M. pilosissima by Smith and Moran (1992), but mixed collections of the two (Mickel 4598b; Breedlove 22928B) and of M. moniliformis and M. zempoaltepetlensis (Mickel 4597b), show clear differences, even when the species grow together. Breedlove 22073, DS, and 22107 are atypical in lacking or nearly lacking setae on the rachises adaxially. They were cited as aberrant Grammitis xiphopteroides by Smith (1981).A
