A classification for extant ferns
Alan R. Smith,Kathleen M. Pryer,Eric Schuettpelz,Petra Korall,Petra Korall,Harald Schneider,Paul G. Wolf +6 more
TL;DR: A revised classification for extant ferns is presented, with emphasis on ordinal and familial ranks, and a synopsis of included genera is provided, reflecting recently published phylogenetic hypotheses based on both morphological and molecular data.

TL;DR: A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.
Journal ArticleDOI
Horsetails and ferns are a monophyletic group and the closest living relatives to seed plants.
Kathleen M. Pryer,Harald Schneider,Alan R. Smith,Raymond Cranfill,Paul G. Wolf,Jeffrey S. Hunt,S. D. Sipes +6 more
TL;DR: It is shown that there are three monophyletic groups of extant vascular plants: (1) lycophytes, (2) seed plants and (3) a clade including equisetophytes (horsetails, psilotophytes) and all eusporangiate and leptosporangiates ferns.
Journal ArticleDOI
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences
Kathleen M. Pryer,Eric Schuettpelz,Paul G. Wolf,Harald Schneider,Harald Schneider,Alan R. Smith,Raymond Cranfill +6 more
TL;DR: The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages.
