Updating taiwanese pteridophyte checklist: A new phylogenetic classification

Ferns and lycophytes of Taiwan display an extraordinarily high diversity. Despite the detailed species documentation, the pteridophyte flora of Taiwan as a whole has never been organized into a phylogenetic framework. Here we provide an updated, phylogeny-based checklist that includes a total of 824 (infra)species taxa, of which eleven are first recorded. In addition, lectotypification of Phlegmariurus salvinioides and new combinations of 25 taxa were made in this study. Our classification scheme is based on the most recent phylogenetic evidence, and for all taxon names accepted here, we provide their best corresponding names in Taiwanese Mandarin. Our appendix and the online file also supply other details, such as synonyms, for the Taiwanese pteridophytes in order to track their nomenclatural changes from the previous floristic documentations. Finally, a discussion group for our community-Taiwan Pteridophyte Group (TPG)-is established online. This platform will allow more users to follow further updates of TPG or to provide any comments on new versions of Taiwan pteridophyte checklist.
