  • Abstract The genus Athyrium composed by 220 species in the world, mainly distributed in the Asia temperate regions. According to the observations of the morphological characters, this study revised the taxonomy and recognized 24 species and 2 varieties in Taiwan. The infrageneric scheme also due to morphology, these Taiwanese species were placed into 5 sections: Sect. Polystichoides, Sect. Echinoathyrium, Sect. Strigoathyrium, Sect. Atkinsonii and Sect. Niponica.
    Basing on the public DNA sequences data (trnL-F and rbcL), including to this study providing, the molecular phylogeny analysis was state in this study. The Maximum Parsimony and Bayesian inference were used in each fragment: trnL-F region length 846 bp, 72 OTUs in 41 species 8 varieties; rbcL 1188 bp, 70 OTUs in 42 species 6 varieties, and combined data: 42 OTUs in 38 species 4 varieties. The phylograms contributed by each datasets are support the infrageneric scheme provided in this study, 5 sections occuring in Taiwan and 2 other sections (Sect. Athyrium and Sect. Yokoscentia) are monophyletic.
    Herein, the key to the species of the Taiwanese Athyrium, science names, descriptions, voucher specimens and notes of each taxa are provided.
