Dryopolystichum is a genus of ferns in the family Lomariopsidaceae,^[1][2] with a single species Dryopolystichum phaeostigma.^[1][3]

Taxonomy

The genus Dryopolystichum was first erected by Edwin Copeland in 1947 for the species Aspidium phaeostigma.^[1] In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus was placed in the family Dryopteridaceae, although left unplaced as to subfamily.^[4] It has since been transferred to the family Lomariopsidaceae as a result of molecular phylogenetic evidence.^[2]
