Unassigned species:
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.
Anemia is a genus of ferns. It is the only genus in the family Anemiaceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the genus may be placed as the only genus in the subfamily Anemioideae of a more broadly defined family Schizaeaceae, the family placement used in Plants of the World Online as of November 2019. Its species are sometimes called flowering ferns, but this term is more commonly applied to ferns of the genus Osmunda. Fronds are dimorphic; in fertile fronds, the two lowermost pinnae are highly modified to bear the sporangia.
Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial.
Gymnosphaera is a genus of tree ferns in family Cyatheaceae.
Plagiogyria is a genus of ferns, the only genus in family Plagiogyriaceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the family may be treated as the subfamily Plagiogyrioideae of a very broadly defined family Cyatheaceae, the placement used for the genus in Plants of the World Online as of November 2019.
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.
Gleichenia is a genus of ferns. Its closest relative is the genus Stromatopteris, restricted to New Caledonia.
Tectariaceae is a family of leptosporangiate ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Tectarioideae of a very broadly defined family Polypodiaceae sensu lato. The family comprises seven genera, of which Tectaria is by far the largest.
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.
Sticherus is a genus of about 80–90 species of fern.
Dicranopteris (forkedfern) is a genus of tropical ferns of the family Gleicheniaceae. There are about 20 described species.
Metaxya is a neotropical genus of ferns in the order Cyatheales. It is the only genus in the family Metaxyaceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the genus may be placed in the subfamily Metaxyoideae of a more broadly defined family Cyatheaceae, the family placement used in Plants of the World Online as of November 2019.
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.
Odontosoria is a genus of ferns in the family Lindsaeaceae.
Austrogramme is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae.
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.
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.
