Athyriaceae
EOL Text
Terrestrial or epilithic ferns. Rhizome creeping or suberect to erect. Fronds monomorphic, approximate or tufted. Stipe and rhachis adaxially grooved, stipe with 2 strap-shaped vascular bundles merging upward into a single U- or V-shaped bundle. Lamina pinnately compound, basiscopically developed or not; veins free or anastomosing. Sori superficial, circular to elongate, linear or J-shaped, borne on the veins, with or without an indusium, homosporus.

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.

Athyriaceae is a family of terrestrial ferns, with a cosmopolitan distribution. It is placed in the eupolypods II clade of the order Polypodiales[1] in the class Polypodiopsida.[2]
Genera[edit]
Athyriaceae contains the following five genera.[1]
Athyriaceae has, in the past, included Cystopteris and Gymnocarpium, now part of Cystopteridaceae. Inversely, this family has by some been subsumed in the family Woodsiaceae, but a Woodsiaceae defined in this way may be paraphyletic if it omits the Onocleaceae and Blechnaceae (as of 2006, the evidence was not clear).[2]
Phylogenic relationships[edit]
The following diagram for the eupolypods II, based on Lehtonen, 2011,[3] and Rothfels & al., 2012,[4] shows a likely phylogenic relationship between the Athyriaceae and the other families of the eupolypods II clade.
