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 …

Premise of the Study For the past one billion years, green plants (Viridiplantae) have
dominated global ecosystems, yet many key branches in their evolutionary history remain …

Background Next-generation sequencing has provided a wealth of plastid genome
sequence data from an increasingly diverse set of green plants (Viridiplantae). Although …

Ferns are the second-most diverse lineage of vascular plants on Earth, yet the best-sampled
time-calibrated phylogeny of the group to date includes fewer than 5% of global diversity …

The origins and the divergence times of the most basal lineages within primates have been
difficult to resolve mainly due to the incomplete sampling of early fossil taxa. The main …

Ferns, with about 12,000 species, are the second most diverse lineage of vascular plants
after angiosperms. They have been the subject of numerous molecular phylogenetic studies …

• Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary
timescale is critical for broad investigations of the evolution of land plants, and for providing …

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 …

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