Abstract Background and Aims Throughout the history of fern classification, familial and
generic concepts have been highly labile. Many classifications and evolutionary schemes …

Phylogeny has long informed pteridophyte classification. As our ability to infer evolutionary
trees has improved, classifications aimed at recognizing natural groups have become …

Throughout the history of the classification of extant ferns (monilophytes) and lycophytes,
familial and generic concepts have been in great flux. For the organisation of lycophytes and …

We present a revised classification for extant ferns, with emphasis on ordinal and familial
ranks, and a synopsis of included genera. Our classification reflects recently published …

Chloroplast DNA sequences are a primary source of data for plant molecular systematic
studies. A few key papers have provided the molecular systematics community with …

The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus
on the early divergences among leptosporangiate lineages. Despite considerable progress …

In an effort to obtain a solid and balanced approximation of global fern phylogeny to serve
as a tool for addressing large‐scale evolutionary questions, we assembled and analyzed …

We present a family–level classification for the eupolypod II clade of leptosporangiate ferns,
one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree …

Over the past 70 years, many fern classifications, nearly all based on morphology, most
explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly …

The monophyletic Pteridaceae accounts for roughly 10% of extant fern diversity and
occupies an unusually broad range of ecological niches, including terrestrial, epiphytic, xeric …
