Aspleniales
3-443.10.00TaxonomyAspleniineae is a monophyletic clade in the PPG1 classification.
Christenhusz has the tendency to treat the whole clade as one extended family Apleniaceae.
The rank can be seen as a subclass. Two subgroups can be seen. One with Aspleniaceae and the clade around Cystopteridaceae, the other with Blechnaceae, Onocleaceae, Athyriaceae, Woodsiaceae, and Thelypteridaceae.Plant theoryIn the Plant theory Aspleniales is the only order in the subclass Aspleniidae. The tentative division in Subphases is as below. The small families Desmophlebiaceae, Diplaziopsidaceae, Hemidictyaceae, and Rhachidosoraceae are included in Cystopteridaceae. Woodsiaceae is included in Onocleaceae. Phegopteridaceae is separated from Thelypteridaceae and placed in Subphase 4, tentatively. This is at the moment the most problematic aspect of the classification of the Aspleniales.Subphases FamiliesPhase Remedy code Family
