Unraveling the phylogeny of polygrammoid ferns (Polypodiaceae and Grammitidaceae): exploring aspects of the diversification of epiphytic plants.
We explore the phylogeny of the polygrammoid ferns using nucleotide sequences derived from three plastid loci for each of 98 selected species. Our analyses recovered four major monophyletic lineages:Expand

A community‐derived classification for extant lycophytes and ferns
Phylogeny has long informed pteridophyte classification. As our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasinglyExpand

Phylogenetic Relationships among the Genera of Taxodiaceae and Cupressaceae: Evidence from rbcL Sequences
DNA sequences from the plastid gene rbcL were used to assess relationships among genera of the conifer families Taxodiaceae and Cupressaceae s. str. Phylogenetic analyses produced four mostExpand

Phylogeny and evolution of grammitid ferns (Grammitidaceae): a case of rampant morphological homoplasy
We conducted phylogenetic analyses of the fern family Grammitidaceae using sequences from two cpDNA genes and from morphological characters. Data were obtained for 73 species from most recognizedExpand

Geographic distributions of homosporous ferns: does dispersal obscure evidence of vicariance?
The central problem in biogeography is that interactions between different processes result in the formation of historical patterns, such that it is difficult to discriminate the relative roles ofExpand

Serpocaulon (Polypodiaceae), a new genus segregated from Polypodium
We describe the neotropical fern genus Serpocaulon (Polypodiaceae), segregated from Polypodium, and make new combinations for the forty known species. Serpocaulon has been recognized previously as aExpand

Molecular phylogenetics and historical biogeography of Hawaiian Dryopteris (Dryopteridaceae).
The fern genus Dryopteris (Dryopteridaceae) is represented in the Hawaiian Islands by 18 endemic taxa and one non-endemic, native species. The goals of this study were to determine whether DryopterisExpand

Systematic inferences from spore and stomate size in the ferns
Size of equivalent cells has traditionally been assumed to be constant within species and variable between species. Systematists have commonly measured cells with constant form, such as spores andExpand

Genetic evidence for allopolyploidy in the neotropical fern hemionitis pinnatifida (Adiantaceae) and the reconstruction of an ancestral genome
Genetic evidence from enzyme electrophoresis and restriction site analyses of cpDNA was employed to explore the origin of the tetraploid Hemionitis pinnatifida by determining the role of diploidExpand

Origin of the endemic fern genus Diellia coincides with the renewal of Hawaiian terrestrial life in the Miocene
The enigmatic fern genus Diellia, endemic to the Hawaiian archipelago, consists of five extant and one recently extinct species. Diellia is morphologically highly variable, and a unique combinationExpand
