Discusión taxonómica
This is primarily a species of western and central Mexico. Among the brown-stiped species of Pecluma, P. ferruginea is distinct in its golden brown, non-comose rhizome scales, small fronds, and conspicuous capsular setulae; it also has persistent rachis scales abaxially. Copeland (1955: 440) discussed it his treatment of Ctenopteris, a genus belonging to the Grammitidaceae.
Evans (1968: 227) cited a specimen (Barkelew 236, US! p.p.) from the Revillagigedo Islands as this species, but this specimen and a duplicate in UC are referable to P. alfredii var. occidentalis. Pecluma alfredii has been collected many times on Isla del Socorro, but P. ferruginea is not known from there.
