BackgroundPolystichum (Dryopteridaceae) is probably the third largest fern genus in the world and contains ca. 500 species. Species of Polystichum occur on all continents except Antarctica, but its highest diversity is found in East Asia, especially Southwest China and adjacent regions. Previous studies typically had sparse taxon sampling and used limited DNA sequence data. Consequently, the majority of morphological hypotheses/classifications have never been tested using molecular data…

An update and reassessment of fern and lycophyte diversity data in the Japanese Archipelago
The fern and lycophyte flora of Japan comprising 721 native taxa (including subspecies and varieties) plus 371 interspecific hybrids was reassessed using a nearly comprehensively sampled distribution
Pteridryaceae: A new fern family of Polypodiineae (Polypodiales) including taxonomic treatments
TLDR
Pteridrys and related taxa based on six plastid markers are resolved and a new family, Pteridryaceae, is proposed to establish to accommodate the DMPP clade, which can not be unambiguously recognized by any of the 13 morphological characters analyzed.
A global plastid phylogeny of the fern genus Asplenium (Aspleniaceae)
The infrageneric relationships and taxonomy of the largest fern genus, Asplenium (Aspleniaceae), have remained poorly understood. Previous studies have focused mainly on specific species complexes

Origin of Hawaiian Polystichum (Dryopteridaceae) in the context of a world phylogeny.
TLDR
The origin of the Hawaiian species of Polystichum is the result of multiple migrations to the islands, rather than single migrations yielding nearly all the local diversity as in the angiosperms, which provides a modern test of the premise that propagule vagility has a central role in determining pattern of evolution.
Asian origin for Polystichum (Dryopteridaceae) based on rbcL sequences
TLDR
The phylogenetic and divergence time estimation results lead us to suggest that Polystichum s.l. originated in Asia in the late Late Cretacous and migrated into other places in the world in early Eocene.
Phylogeny of Chinese Polystichum (Dryopteridaceae) based on chloroplast DNA sequence data (trnL-F and rps4-trnS)
TLDR
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.
Inclusion of the Eastern Asia endemic genus Sorolepidium in Polystichum (Dryopteridaceae): Evidence from the chloroplast rbcL gene and morphological characteristics
TLDR
Molecular data establish that Sorolepidium is deeply nested within the large genus Polystichum and has a close relationship with P. duthiei and P. lachenense in the model-based analyses.
Asian origin for Polystichum (Dryopteridaceae) based on rbcL sequences
TLDR
The phylogenetic and divergence time estimation results lead us to suggest that Polystichum s.l. originated in Asia in the late Late Cretacous and migrated into other places in the world in early Eocene.
Major evolutionary events in the origin and diversification of the fern genus Polystichum (Dryopteridaceae).
TLDR
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.
Phylogeny and biogeography of exindusiate Andean Polystichum (Dryopteridaceae).
TLDR
The monophyletic exindusiate Andean Polystichum lineage diverged from a Mexican lineage in the middle Miocene and diversified in the central Andes before dispersing northward, corresponding with episodes of uplift in the tropical Andes.
A global plastid phylogeny of the brake fern genus Pteris (Pteridaceae) and related genera in the Pteridoideae
TLDR
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.
Chloroplast DNA evolution and systematics of Phanerophlebia (Dryopteridaceae) and related fern genera.
TLDR
Reticulate venation, previously considered an important taxonomic character for infrageneric classification in Phanerophlebia, most likely evolved independently twice within the genus.
