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]

Species

[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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
