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.
