A taxonomic revision of Hymenophyllaceae

A new classification of Hymenophyllaceae, consisting of nine genera (Hymenophyllum, Didymoglossum, Crepidomanes, Polyphlebium, Vandenboschia, Abrodictyum, Trichomanes, ( ephalomanes and Callistopteris) is proposed. Every genus, subgenus and section chiefly corresponds to the monophyletic group elucidated in molecular phylogenetic analyses based on chloroplast sequences. Brief descriptions and keys to the higher taxa are given, and their representative members are enumerated, including some new combinations.
