Athyrioideae is a subfamily of terrestrial ferns, with a cosmopolitan distribution.

Taxonomy

Earlier classifications

Previously treated as a separate family, Athyriaceae Alston,[1][2] in 2014 Christenhusz and Chase submerged it as subfamily Athyrioideae within family Aspleniaceae.[3]

Originally considered as a member of the Eupolypods II clade, the Athyriaceae was related to other families in the clade as in this cladogram:[4][5]

eupolypods II

 

Cystopteridaceae

 
 

 

 

Rhachidosoraceae

 
 

 

Diplaziopsidaceae

 
 

 

Aspleniaceae

 
 

Hemidictyaceae

 
 
 
 
 

 

Thelypteridaceae

 
 

 

Woodsiaceae

 
 

 

 

Onocleaceae

 
 

Blechnaceae

 
 
 

Athyriaceae

 
 
 
 
 
 

The Athyriaceae 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]

Christenhusz and Chase classification

Athyrioideae is placed within the Aspleniaceae as follows:[3]

Aspleniaceae

 

Cystopteridoideae (Acystopteris, Cystoathyrium, Cystopteris, Gymnocarpium)

 
 

 

 

Rhachidosoroideae (Rhachidosorus)

 
 

 

Diplaziopsidoideae (Diplaziopsis, Homalosorus)

 
 

Asplenioideae (Asplenium, Hemidictyum, Hymenasplenium)

 
 
 
 

 

Thelypteridoideae (Macrothelypteris, Phegopteris, Thelypteris)

 
 

 

Woodsioideae (Woodsia)

 
 

 

Blechnoideae (Blechnum, Onoclea, Stenochlaena, Woodwardia)

 
 

Athyrioideae (Athyrium, Cornopteris, Deparia, Diplazium)

Athyrioideae contain the following five genera.[1]
