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]

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)

Subdivision

Athyrioideae contain the following five genera.[1]

with the following phylogenetic relationship: [6][7]

Athyriaceae

Deparia

Diplazium

Anisocampium

Cornopteris

Athyrium
