Pteris (brake) is a genus of about 300 species of ferns in the subfamily Pteridoideae of the family Pteridaceae. They are native to tropical and subtropical regions, southward to New Zealand, Australia, and South Africa, north to Japan and North America. 78 species are found in China. Some species of Pteris have considerable economic and ecological value, such as Pteris multifida, Pteris ensiformis, Pteris vittata can be used for ornamental purposes; as a hyperaccumulator, Pteris multifida and Pteris vittata can be used to control soil pollution.
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Phlegmariurus is a genus of lycophyte plants in the family Lycopodiaceae. The genus is recognized in the Pteridophyte Phylogeny Group classification of 2016, but not by some other sources, which keep it in a broadly defined Huperzia.
Alsophila is a genus of tree ferns in the family Cyatheaceae. It has also been considered to be a section in the subgenus Cyathea of the genus Cyathea.
Dennstaedtia is a mostly tropical and subtropical genus of ferns described as a genus in 1801. Hayscented fern, or Cup ferns, are common names for some species in this genus. Its best-known member is probably the temperate North-American hay-scented fern, Dennstaedtia punctilobula, which forms extensive clonal ground-cover colonies on level surfaces in the Appalachian area.
Bolbitis is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Ceradenia is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).
Tectaria is a genus of fern in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. Halberd fern is a common name for species in this genus.
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.
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.
Didymoglossum is a tropical genus of ferns in the family Hymenophyllaceae. It comprises more than 30 epilithic or low-epiphytic species under two subgenera. 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.
Pyrrosia is a genus of about 100 fern species in the polypod family, Polypodiaceae. Like other species in Polypodiaceae, the species of Pyrrosia are generally epiphytic on trees or rocks, a few species are terrestrial. The Latin name of Pyrrosia comes from the Greek pyrrhos (red), which refers to its leaves that are red due to the sporangia.
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.
Amauropelta is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink the genus into a very broadly defined genus Thelypteris.
Goniopteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Goniopteris into a very broadly defined genus Thelypteris.
Serpocaulon is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is native to Northern and Southern America.
