Woodsia is a genus of ferns in the family Woodsiaceae. Species of Woodsia are commonly known as cliff ferns.[4]: 224  In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it was the only genus in the family Woodsiaceae.[1] In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence.[5] As of June 2023, Plants of the World Online continued to treat Physematium as a synonym of Woodsia.[6]

[edit]

There are about 25–30 species of the genus Woodsia. As of June 2023, World Ferns hosted at World Plants accepted the following species:[7]
