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.
Coriaria is the sole genus in the family Coriariaceae, which was described by Linnaeus in 1753. It includes 14 species of small trees, shrubs and subshrubs, with a widespread but disjunct distribution across warm temperate regions of the world, occurring as far apart as the Mediterranean region, southern and eastern Asia, New Zealand, the Pacific Ocean islands, and Central and South America.
Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera, divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level.
Athyrium (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales. Its genus name is from Greek a- ('without') and Latinized Greek thyreos ('shield'), describing its inconspicuous indusium . The common name "lady fern" refers in particular to the common lady fern, Athyrium filix-femina.
Pteris adscensionis is a fern species in the subfamily Pteridoideae of the family Pteridaceae. It is endemic to Ascension Island, and there are thought to be fewer than 500 individuals left in the wild. Its natural habitat has been severely reduced due to the large number of species introduced to the island when it was first settled in the 18th century.
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.
Pteris vittata, the Chinese brake, Chinese ladder brake, or simply ladder brake, is a fern species in the Pteridoideae subfamily of the Pteridaceae. It is indigenous to Asia, southern Europe, tropical Africa, and Australia. The type specimen was collected in China by Pehr Osbeck.
Adiantum pedatum, the northern maidenhair fern or five-fingered fern, is a species of fern in the family Pteridaceae, native to moist forests in eastern North America. Like other ferns in the genus, the name maidenhair refers to the slender, shining black stipes.
Pteris platyzomopsis, synonym Platyzoma microphyllum, is a species of fern in the family Pteridaceae. When placed in the genus Platyzoma, it was the only species; the genus was sometimes placed in its own family, Platyzomaceae. The species is native to northern Australia, occurring in the Kimberley region of Western Australia, in the Northern Territory and Queensland, and in northern New South Wales, where it is considered endangered. Vernacular names include braid fern.
Pteris tremula, commonly known as Australian brake, tender brake, tender brakefern, shaking brake is a fern species of the family Pteridaceae native to sheltered areas and forests in eastern Australia and New Zealand. It has pale green, lacy fronds of up to 2 meters in length, with an erect, tufted rhizome that is covered with narrow brown scales. It is fast-growing and easy to grow in cultivation, but can become weedy.
Cryptogramma crispa, the parsley fern, is an Arctic–alpine species of fern. It produces separate sterile and fertile fronds, up to 30 cm (12 in) tall, and is a pioneer species on acidic screes.
Pteris ensiformis, the slender brake, silver lace fern, sword brake fern, or slender brake fern, is a plant species of the genus Pteris in the family Pteridaceae. It is found in Asia and the Pacific.
Pteris lydgatei is a rare fern species in the Pteridoideae subfamily of the Pteridaceae. It is known by the common name Lydgate's brake and is endemic to Hawaii, where it is known from the islands of Oʻahu, Molokaʻi, and Maui. It was once thought to be extinct until it was rediscovered in the 1990s. There are fewer than 40 individuals in the wild. This is a federally listed endangered species of the United States.
Calciphilopteris is a genus of ferns in the family Pteridaceae. It is native to India and China, southward to Australia. Its four species grow in crevices in limestone or they cling to the rock itself.
Pteris longifolia, the longleaf brake is a species of fern in the Pteridoideae subfamily of the Pteridaceae.
Rhachidosorus is a genus of ferns in the order Polypodiales. It is the only genus in the family Rhachidosoraceae in the Pteridophyte Phylogeny Group classification of 2016. Alternatively, the genus may be placed in the subfamily Rhachidosoroideae of a more broadly defined family Aspleniaceae, the family placement used in Plants of the World Online as of November 2019.
Pteridoideae is one of the five subfamilies of the fern family Pteridaceae. This subfamily contains about 14 genera and around 400 species.
Pteris cretica, the Cretan brake, ribbon fern, or Cretan brake fern, is a species of evergreen fern in the family Pteridaceae, native to Europe, Asia and Africa.
Hemionitis is a genus of ferns in the subfamily Cheilanthoideae of the family Pteridaceae. Its circumscription varies greatly in different systems of fern classification. In the Pteridophyte Phylogeny Group classification of 2016, it was one of more than 20 genera in the subfamily Cheilanthoideae, and was said to have five species. Other sources treat it as the only genus in the subfamily, and so accept about 450 species. With the restricted circumscription, species are native to tropical America.
