Genera

The Woodsiaceae or Cliff Ferns is a family of ferns in the Eupolypods II clade of the order Polypodiales, in the class Polypodiopsida.[1] It contains the three genera Cheilanthopsis, Hymenocystis, and Woodsia. However, the first two are very similar to Woodsia and may be merged into it at some point.[2]

Phylogenic relationships[edit]

Woodsiaceae formerly included the members of the families Athyriaceae and Diplaziopsidaceae, but analysis has consistently shown that they should be treated as separate families.[2] The following diagram for the eupolypods II, based on Lehtonen, 2011,[3] and Rothfels & al., 2012,[4] shows a likely phylogenic relationship between the Woodsiaceae and the other families of the eupolypods II clade.
