    • 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 ...
    • A revised family-level classification for eupolypod II ferns (Polypodiidae: Polypodiales) 

      Rothfels, CJ; Sundue, MA; Kuo, L; Larsson, A; Kato, M; Schuettpelz, E; Pryer, KM (Taxon, 2012-01-01)
      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 of life where family-level ...
    • Deciphering the origins of apomictic polyploids in the Cheilanthes yavapensis complex (Pteridaceae). 

      Grusz, AL; Windham, MD; Pryer, KM (American journal of botany, 2009-09)
      Deciphering species relationships and hybrid origins in polyploid agamic species complexes is notoriously difficult. In this study of cheilanthoid ferns, we demonstrate increased resolving power for clarifying the origins ...
    • Divergence times and the evolution of epiphytism in filmy ferns (Hymenophyllaceae) revisited 

      Hennequin, S; Schuettpelz, E; Pryer, KM; Ebihara, A; Dubuisson, J (International Journal of Plant Sciences, 2008-11-01)
      Although the phylogeny of the filmy fern family (Hymenophyllaceae) is rapidly coming into focus, much remains to be uncovered concerning the evolutionary history of this clade. In this study, we use two data sets (108-taxon ...
    • DNA barcoding exposes a case of mistaken identity in the fern horticultural trade. 

      Pryer, Kathleen M; Schuettpelz, Eric; Huiet, Layne; Grusz, Amanda L; Rothfels, Carl J; Avent, Tony; Schwartz, David; ... (8 authors) (Molecular ecology resources, 2010-11)
      Using cheilanthoid ferns, we provide an example of how DNA barcoding approaches can be useful to the horticultural community for keeping plants in the trade accurately identified. We use plastid rbcL, atpA, and trnG-R sequence ...
    • Metaxya lanosa, a second species in the genus and fern family Metaxyaceae 

      Smith, AR; Tuomisto, H; Pryer, KM; Hunt, JS; Wolf, PG (Systematic Botany, 2001-10-11)
      We describe and illustrate Metaxya lanosa, the second known species in the genus and the fern family Metaxyaceae (Pteridophyta). It is currently known from four different watersheds in Amazonian Peru and Venezuela. It can ...
    • 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 ...
    • rbcL data reveal two monophyletic groups of filmy ferns (Filicopsida: Hymenophyllaceae). 

      Pryer, KM; Smith, AR; Hunt, JS; Dubuisson, JY (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 ...
