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.
