New Progress in the Phylogeny and Classification of the Largest Fern Family Dryopteridaceae
Author(s): Li-Bing Zhang*
Dryopteridaceae are the largest fern family containing over 2,100 species worldwide found in various habitats. Previous studies identified three major clades and two subclades and proposed a classification with three subfamilies. However, some critical relationships remained unresolved and some genera remained unsampled. In a most recent study, all the genera of Dryopteridaceae were sampled. Complete chloroplast genomes for 91 species were obtained and a highly supported phylogenetic tree for all extant genera within the family was reconstructed. Based on the new phylogeny and morphological analysis, a classification with seven subfamilies and 24 genera was proposed... View more»
