Thelypteridaceae is a family of about 900 species of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the suborder Aspleniineae. Alternatively, the family may be submerged in a very broadly defined family Aspleniaceae as the subfamily Thelypteridoideae.
Phegopteris is a genus of ferns in the family Thelypteridaceae, subfamily Phegopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. They are known collectively as the beech ferns. Species are native to Asia, North America and Europe.
Microsorum is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The species are tropical. Like most ferns, they grow from rhizomes, rather than roots. The genus name is often misspelled "Microsorium" or "Microsoreum". It includes some species that are lithophytic rheophytes.
Aleuritopteris is a genus of ferns in the Cheilanthoideae subfamily of the Pteridaceae. As with some other genera of the Cheilanthoideae, molecular phylogenetic studies have suggested that it is not monophyletic, and so may need to be circumscribed differently in future.
Thelypteris is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales. Two radically different circumscriptions of the genus are in use as of January 2020. In the Pteridophyte Phylogeny Group classification of 2016, the genus is a very small one with about two species. In other approaches, the genus is the only one in the subfamily Thelypteridoideae, and so includes between 875 and 1083 species.
Cyclogramma is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Cyclogramma into a very broadly defined genus Thelypteris.
Arthropteris is a small genus of ferns in family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. It was previously placed in the families Oleandraceae or Davalliaceae. The genus is native to Australia, Europe, Asia and Africa. Around 12 to 21 species are considered part of this genus. The name Arthropteris is from the Greek, meaning "jointed fern", referring to the joint at the base of the petiole.
Christella is a genus of around 70-80 species of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Christella into a very broadly defined genus Thelypteris. The genus was named after Konrad H. Christ, a Swiss botanist. The distribution of these plants is mostly in the tropics and sub tropical areas. An Australian example is C. dentata.
Cyclosorus is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Cyclosorus into a very broadly defined genus Thelypteris, or expand the genus to include other genera which PPG I keeps separate. Thus the online Flora of China suggests there are about 250 species compared to the two species suggested in PPG I.
Pronephrium is a genus of ferns in the family Thelypteridaceae in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Pronephrium into a very broadly defined genus Thelypteris. Some species were split off into the genera Abacopteris, Grypothrix and Menisciopsis in 2021 as a result of a phylogenetic study of the family Thelypteridaceae.
Vandenboschia is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 but not by some other sources.
Parathelypteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Parathelypteris into a very broadly defined genus Thelypteris.
Stegnogramma is a genus of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Stegnogramma into a very broadly defined genus Thelypteris.
Coryphopteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Arthrobotrya is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016. The genus is native to Australia and New Zealand.
Pleocnemia is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Teratophyllum is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016. The genus is native to Malesia.
Lomagramma is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Parapolystichum is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016. The genus is mainly native to the tropics, although its range extends to southeastern Australia.
Triplophyllum is a genus of ferns in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
