Genus Crepidomanes (C. Presl) C.Presl (Presl 1849)

This genus is mostly paleotropical with more than 25 species including two taxa in Americas (Dubuisson et al. 2013b). All species are epiphytic or lithophytic, dwarf to medium-size plants characterized by long-creeping, filiform and rootless rhizomes bearing pending flabellate (for the smallest) to highly divided (for the largest) fronds. The marginal sori have a tubular base and lips more or less developed (see Fig. 2C). In addition, laminae often exhibit false veins (Fig. 2E) or folds imitating veins.
