Cyrtomium Explained

Cyrtomium is a genus of about 35 species of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Species are native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus Polystichum, with 2016 research suggesting it should be included in a clade sister to Polystichum s.s.^[1]
