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

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 …

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 …

Background California is a world floristic biodiversity hotspot where the terms neo-and paleo-
endemism were first applied. Using spatial phylogenetics, it is now possible to evaluate …

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 …

This paper reviews 31 groups in ferns and lycophytes hypothesized to show eastern Asian–
North American disjunctions. Fourteen lineages have been supported by recent …

We explore the phylogeny of the polygrammoid ferns using nucleotide sequences derived
from three plastid loci for each of 98 selected species. Our analyses recovered four major …

A new classification of Hymenophyllaceae, consisting of nine genera (Hymenophyllum,
Didymoglossum, Crepidomanes, Polyphlebium, Vandenboschia, Abrodictyum …

Background DNA barcoding is expected to be an effective identification tool for organisms
with heteromorphic generations such as pteridophytes, which possess a morphologically …
