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 ... -
A plastid phylogeny of the cosmopolitan fern family cystopteridaceae (Polypodiopsida)
(Systematic Botany, 2013-06-01)Among the novel results of recent molecular phylogenetic analyses are the unexpectedly close evolutionary relationships of the genera Acystopteris, Cystopteris, and Gymnocarpium, and the phylogenetic isolation of these genera ... -
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 ... -
Molecular phylogenetic relationships and morphological evolution in the heterosporous fern genus Marsilea
(Systematic Botany, 2007-01-01)Using six plastid regions, we present a phylogeny for 26 species of the heterosporous fern genus Marsilea. Two well-supported groups within Marsilea are identified. Group I includes two subgroups, and is relatively species-poor. ... -
On the phylogenetic position of Cystodium: It's not a tree fern - It's a polypod!
(American Fern Journal, 2006-04-01)The phylogenetic position of Cystodium J. Sm. is studied here for the first time using DNA sequence data. Based on a broad sampling of leptosporangiate ferns and two plastid genes (rbcL and atpB), we show that Cystodium ...
