This broad generic concept has been adopted in several recent taxonomic treatments, including the Pteridophyte Phylogeny Group I. However, the infrageneric taxonomy of Deparia still needs further revision. In this study, we provide a new infrageneric classification with five sections and three subsections based on the phylogenetic evidence.
