As the oldest extant lineages of land plants, bryophytes provide a living laboratory in which
to evaluate morphological adaptations associated with early land existence. In this paper we …

▪ Abstract Morphological and molecular analyses resolve many aspects of vascular plant
phylogeny, though others remain uncertain. Vascular plants are nested within bryophytes; …

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 …

In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in
Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and …

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 …
