Biology:Woodsia

From HandWiki

Woodsia is a genus of ferns in the family Woodsiaceae. Species of Woodsia are commonly known as cliff ferns.[1]: 224  In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it was the only genus in the family Woodsiaceae.[2] In 2020, Physematium was split off from Woodsia on the basis of molecular phylogenetic evidence.[3] As of June 2023, Plants of the World Online continued to treat Physematium as a synonym of Woodsia.[4]

Phylogeny
