A classification for extant ferns
(Taxon, 2006-01-01)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 phylogenetic hypotheses based ... -
Fern phylogeny inferred from 400 leptosporangiate species and three plastid genes
(Taxon, 2007-01-01)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 the most inclusive molecular dataset for ... -
Maidenhair ferns, adiantum, are indeed monophyletic and sister to shoestring ferns, vittarioids (Pteridaceae)
(Systematic Botany, 2016-01-01)© 2016 by the American Society of Plant Taxonomists. Across the tree of life, molecular phylogenetic studies often reveal surprising relationships between taxa with radically different morphologies that have long obscured ... -
Phylogeny and divergence time estimates for the fern genus Azolla (Salviniaceae)
(International Journal of Plant Sciences, 2007-10-22)A phylogeny for all extant species of the heterosporous fern genus Azolla is presented here based on more than 5000 base pairs of DNA sequence data from six plastid loci (rbcL, atpB, rps4, trnL-trnF, trnG-trnR, and rps4-trnS). ... -
Phylogeny and evolution of ferns (monilophytes) with a focus on the early leptosporangiate divergences.
(American journal of botany, 2004-10)The phylogenetic structure of ferns (= monilophytes) is explored here, with a special focus on the early divergences among leptosporangiate lineages. Despite considerable progress in our understanding of fern relationships, ... -
Plastid atpA data provide improved support for deep relationships among ferns
(Taxon, 2006-01-01)DNA sequence data and phylogenetic approaches have contributed greatly to our understanding of fern relationships. Nonetheless, the datasets analyzed to date have not been sufficient to definitively resolve all parts of ... -
rbcL data reveal two monophyletic groups of filmy ferns (Filicopsida: Hymenophyllaceae).
(American journal of botany, 2001-06)The "filmy fern" family, Hymenophyllaceae, is traditionally partitioned into two principal genera, Trichomanes s.l. (sensu lato) and Hymenophyllum s.l., based upon sorus shape characters. This basic split in the family has ...
