A taxonomic revision of Hymenophyllaceae
A new classification of Hymenophyllaceae, consisting of nine genera and every genus, subgenus and section chiefly corresponds to the mono phyletic group elucidated in molecular phylogenetic analyses based on chloroplast sequences is proposed.
A community‐derived classification for extant lycophytes and ferns
A modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community‐based approach, that uses monophyly as the primary criterion for the recognition of taxa, but also aims to preserve existing taxa and circumscriptions that are both widely accepted and consistent with the understanding of pteridophyte phylogeny.
Molecular Species Identification with Rich Floristic Sampling: DNA Barcoding the Pteridophyte Flora of Japan
This study demonstrates the overall effectiveness of DNA barcodes for species identification in the Japanese pteridophyte flora, and is especially anticipated to be helpful for identification of non-hybridizing gametophytes.
Nuclear DNA, chloroplast DNA, and ploidy analysis clarified biological complexity of the Vandenboschia radicans complex (Hymenophyllaceae) in Japan and adjacent areas.
The results based on 266 individuals collected from 174 localities throughout Japan and Taiwan suggest that complicated hybridizations have occurred involving at least three parental diploid species from within the V. radicans complex and Vandenboschia liukiuensis.
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.
rbcL and matK Earn Two Thumbs Up as the Core DNA Barcode for Ferns
This study provides the first endorsement of the two-locus barcode (rbcL+matK) in ferns, and favors trnL-F over trnH-psbA as a potential back-up locus.
RbcL Phylogeny of Japanese Pteridophyte Flora and Implications on Infrafamilial Systematics
A molecular phylogenetic analysis of the Japanese pteridophyte flora was performed using chloroplast rbcL sequences of 93% of Japanese taxa and noteworthy or novel results on the infrafamilal taxonomy of the pterodophytes are documented by family.
