Dryopteris is one of the largest and most taxonomically complex fern genera in the Dryopteridaceae, with 127 species occurring throughout temperate, sub-temperate, subtropical, and tropical China. Investigations of the evolutionary relationships of a subset of these Chinese Dryopteris species, using DNA sequence-based methods, specifically tested the monophyly of the genus and the validity of the previous subgeneric classifications. Sixty species of Dryopteris, four closely related non… 
Molecular circumscription and major evolutionary lineages of the fern genus Dryopteris (Dryopteridaceae)
The paraphyly of Dryopteris is confirmed and the first strong molecular evidence on the monophyly of Acrophorus, Diacalpe, Dryopsis, Nothoperanema, and Peranema is provided, which strongly suggests that the current taxonomy of this genus is in need of revision.
Phylogeny of Chinese Polystichum (Dryopteridaceae) based on chloroplast DNA sequence data (trnL-F and rps4-trnS)
Three subclades resolved within Polystichum sensu stricto (s.s.) clade do not correspond with recent sectional classifications, and it is outlined the issues relevant to a new classification for the genus.
A plastid phylogeny of the fern genus Arachniodes (Dryopteridaceae).
Molecular Phylogeny of the Fern Family Dryopteridaceae Inferred from Chloroplast rbcL and atpB Genes
This study identifies four major lineages within the Dryopteridaceae, each strongly supported as a monophyletic group, and shows two large genera, Dryopteris and Polystichum, are shown to be polyphyletic and need to be revised in the future.
The inclusion of Acrophorus, Diacalpe, Nothoperanema, and Peranema in Dryopteris: The molecular phylogeny, systematics, and nomenclature of Dryopteris subg. Nothoperanema (Dryopteridaceae)
This study clearly demonstrated that the currently defined Dryopteris is paraphyletic in relation to a clade containing the monophyletic Acrophorus, Diacalpe, Nothoperanema, and Peranema.
A global plastid phylogeny of the brake fern genus Pteris (Pteridaceae) and related genera in the Pteridoideae
DNA sequences of six plastid loci of 146 accessions representing 119 species of Pteris and 18 related genera were used to infer a phylogeny using maximum‐likelihood, Bayesian‐inference and maximum‐parsimony methods.
Phylogeny, divergence times, and historical biogeography of New World Dryopteris (Dryopteridaceae).
New World Dryopteris are not monophyletic; vicariance has dominated the history of the North American species, while long-distance dispersal prevails in the Central and South Brazilian species, a pattern not previously seen in plants.
Phylogenetics and historical biogeography of Lomaridium(Blechnaceae: Polypodiopsida)
The phylogenetic relationships and the historical biogeography of the species of Lomaridium, a genus including most of the hemiepiphytic species in the Blechnaceae, are unraveled, suggesting that the early history of the family was complex biogeographically, with extensive long-distance dispersal events.

Molecular Studies of Representative Species in the Fern Genus Elaphoglossum (Dryopteridaceae) Based on cpDNA Sequences rbcL, trnL‐F, and rps4‐trnS
Mapping of morphological characters onto the molecular phylogeny reveals how scale structure, rhizome morphology, presence/absence of hydathodes and/or phyllopodia, and general growth form are important synapomorphies for sectional and subsectional classification in Elaphoglossum.
Phylogenetics and biogeography of the neotropical fern genera Jamesonia and Eriosorus (Pteridaceae).
Molecular phylogenetic analyses for this study suggest that neither genus is itself monophyletic and that several independent lineages with the jamesonia morphotype have each undergone a fairly recent radiation in páramo ecosystems.
Major evolutionary events in the origin and diversification of the fern genus Polystichum (Dryopteridaceae).
Examining rbcL sequences and morphological characters from 55 fern taxa suggests that the common ancestor of Polystichum s.s.l. and Phanerophlebia had evolved the common features of the alliance, including ciliate petiole-base scales, once-pinnate fronds, ultimate segments with scarious tips, peltate indusia, and microscales.
rbcL gene sequences provide evidence for the evolutionary lineages of leptosporangiate ferns.
To compare competing classifications, DNA sequences of a chloroplast gene were obtained and phylogenetic trees were inferred by the neighbor-joining and the parsimony methods that provided insights concerning major general evolutionary trends in the leptosporangiate ferns.
Intrafamilial Relationships of the Thelypteroid Ferns (Thelypteridaceae)
Data from three chloroplast genes for 27 of the recognized segregates show the Thelypteridaceae to be monophyletic and sister to an unresolved alliance of blechnoid, athyrioid, onocleoid, and woodsioid ferns, and recognition of an intermediate number of genera may be the most reasonable taxonomic course.
Phylogenetic analysis ofIridaceae with parsimony and distance methods using the plastid generps4
A molecular phylogeny of the familyIridaceae based on the plastid generps4 was obtained using both parsimony and distance methods, and shows that the family is monophyletic, and that Isophysis is likely to be the earliest emerging genus.
Phylogenetic Incongruence: Window into Genome History and Molecular Evolution
The field of systematic biology has been revitalized and transformed during the last few decades by the confluence of phylogenetic thinking with ready access to the tools of molecular biology and a growing awareness that reliance on a single data set may often result in insufficient phylogenetic resolution or misleading inferences.
