Other species:
Saccoloma is a fern genus in family Saccolomataceae. It is the only genus in the family in the Pteridophyte Phylogeny Group classification of 2016, but further investigation is needed. It is pantropical and its species are found in wet, shaded forest areas. Saccoloma species are characterized by an omega-shaped (Ω) vascular bundle in the cross-sections of their petioles. The common name soralpouch fern is used for Saccoloma.
Trichomanes is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Colombia. There are also members of the taxa that can grow submersed in water.
Cystopteridaceae is a family of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Aspleniineae of the order Polypodiales, and includes three genera. Alternatively, it may be treated as the subfamily Cystopteridoideae of a very broadly defined family Aspleniaceae.
Lindsaea, common name necklace fern, is a genus of around 180 species of fern, 15 of which reach Australia. The name is in honour of surgeon John Lindsay of Jamaica. The genus is sometimes spelt Lindsaya.
Dicranopteris (forkedfern) is a genus of tropical ferns of the family Gleicheniaceae. There are about 20 described species.
Polyphlebium 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.
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.
Abrodictyum 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, which sink it into a broadly defined Trichomanes.
Cheiropleuria is a genus of ferns in the family Dipteridaceae. Species are found in both temperate and tropical eastern Asia.
Odontosoria is a genus of ferns in the family Lindsaeaceae.
Osmolindsaea is a genus of ferns in the family Lindsaeaceae. Most species are found in southeastern Asia, from West Himalaya and Sri Lanka to Japan and New Guinea. Osmolindsaea latisquama and Osmolindsaea leptolepida are found in Madagascar and the adjacent African mainland.
Tapeinidium is a genus of ferns in the family Lindsaeaceae with about 19 species. Species are native to south-eastern Asia, from Thailand to New Guinea, and into the western Pacific. Tapeinidium pinnatum has been introduced into India.
Austrogramme is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae.
Pterozonium is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are mainly found in north-western South America, as well as Costa Rica.
Syngramma is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to south-east tropical Asia and the Pacific.
Taenitis is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to south-east tropical Asia, Australia and the Pacific.
Tryonia is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. Species are native to the east of Brazil and to Uruguay.
Polytaenium is a genus of ferns in the subfamily Vittarioideae of the family Pteridaceae. Species are native to Mexico and Southern America.
Radiovittaria is a genus of ferns in the subfamily Vittarioideae of the family Pteridaceae. Species are native to southeast Mexico and northern Southern America.
Vaginularia is a genus of ferns in the subfamily Vittarioideae of the family Pteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink the genus into Monogramma, a genus not recognized in PPG I.
