    • A classification for extant ferns 

      Smith, AR; Pryer, KM; Schuettpelz, E; Korall, P; Schneider, H; Wolf, PG (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 

      Schuettpelz, E; Pryer, KM (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 

      Nagalingum, NS; Schneider, H; Pryer, KM (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. ...

    • Plastid atpA data provide improved support for deep relationships among ferns 

      Schuettpelz, E; Korall, P; Pryer, KM (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 ...
