Other species:
Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.
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.
Actinostachys is a genus of small ferns originally included in the genus Schizaea. The genus was segregated on the basis of the flabelliform (fan-shaped) laminae. The genus is colloquially called the ray ferns.
Schizaea is a small genus of specialized ferns in the family Schizaeaceae. Common names include curlygrass fern and comb fern. Some species are very small and inconspicuous, and so may often be overlooked in nature. The genus is distinctive and not at all like the common conception of a fern, though it is still considered a true fern (leptosporangiate). The sterile fronds (trophophylls) are grass-like, and the spore-bearing fertile frond (sporophyll) is similar, but with a small, pinnate fertile segment at its apex. The upper surface of the pinnules bear the sessile capsules. Various of the roughly two dozen species have been reported from widely separated regions, including much of the tropical Old and New World, parts of the Eastern USA, Chile, the Falkland Islands, and various Pacific islands, including several islands of New Caledonia, as well as Australia and New Zealand. In Africa at least two species are endemic to South Africa.
Acrostichum is a fern genus in the Parkerioideae subfamily of the Pteridaceae. It was one of the original pteridophyte genera delineated by Linnaeus. It was originally drawn very broadly, including all ferns that had sori apparently "acrostichoid", or distributed in a uniform mass across the back of the frond, rather than organized in discrete sori. This led Linnaeus to include such species as Asplenium platyneuron in the genus, because the specimen he received had sori so crowded that it appeared acrostichoid.
Calochlaena is a genus of ferns within the family Dicksoniaceae. Although these ground ferns resemble bracken, they are only distantly related. Five species are known from Melanesia, Polynesia and eastern Australia. Calochlaena dubia, is a common fern of the east coast of Australia. The name is derived from the Ancient Greek kalos "beautiful" and chlaina "cloak", and refers to the soft hairs on the species.
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.
Lonchitis is a neotropical genus of ferns. It is the sole genus in the family Lonchitidaceae. At one time Lonchitis was placed in the Dennstaedtiaceae, and then transferred to the Lindsaeaceae, before being placed in its own family.
Pityrogramma, the silverback ferns, or goldback ferns, is a fern genus in the subfamily Pteridoideae of the family Pteridaceae.
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.
Diplopterygium is a genus of ferns in the family Gleicheniaceae.
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.
Austrogramme is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae.
Onychium 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.
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.
