Pteris
''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 (35 endemic) 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. Many of them have linear frond segments, and some have sub-palmate division. Like other members of the Pteridaceae, the frond margin is reflexed over the marginal sorus, sori. The outermost layer is the single layered epidermis without stomata. The cortex is differentiated into outer and inner cortical region. The vascular cylinder is an wikt:amphiphloic, amphiphloic siphonostele. The term "brak ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pteris Vittata
''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. Habitat and distribution ''Pteris vittata'' is native and widespread in the paleotropics: found from the east, to the south tropical, and southern Africa (in Angola; Kenya; Lesotho; Malawi; Mozambique; Namibia; Tanzania (including the Zanzibar Archipelago); Cape Province, Free State, KwaZulu-Natal, and Transvaal in South Africa; Eswatini; Uganda; Zambia; and Zimbabwe); temperate and tropical Asia (in the provinces of Anhui, Gansu, Guangdong, Guangxi, Guizhou, Hubei, Jiangxi, Sichuan, Xizang, and Yunnan in China; the prefectures of Honshu, Kyushu, Shikoku, and the Ryukyu Islands of Japan; and Thailand); and Australia, in the states of New South Wales, Queensland, Victoria, and Western Australia.

Pteris Ensiformis
''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. Uses Beverages It is the most common ingredient of traditional herbal drinks in Taiwan containing different phenolic compounds : kaempferol 3-O-α-l-rhamnopyranoside-7-O-[α-d-apiofuranosyl-(1-2)-β-d-glucopyranoside], 7-O-caffeic acid, caffeoylhydroxymaltol 3-O-β-d-glucopyranoside, hispidin 4-O-β-d-glucopyranoside, kaempferol 3-O-α-l-rhamnopyranoside-7-O-β-d-glucopyranoside, caffeic acid, 5-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid. This plant is resistant to arsenic-induced oxidative stress. Benzoyl-beta-D-glucoside, as well as pterosin sesquiterpenes can be found in ''P. ensiformis''. Cultivation ''Pteris ensiformis'' is cultivated as an ornamental plant for tropical and subtropical climate gardens, and as a house plant. ;Culti ...

Pteris Platyzomopsis
''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. Characteristics ''Pteris platyzomopsis'' is unusual among ferns in that it may display incipient heterospory. Microsporangia produce 32 microspores, each 71-101μm in diameter. Megasporangia produce 16 megaspores, each 163-183μm in diameter. Microspores produce a filamentous microgametophyte, which lacks rhizoids and gives rise only to antheridia. Megaspores produce spatulate megagametophytes with rhizoids, which produce archegonia. Megagametophytes may later produce antheridia, making them functi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pteris Adscensionis
''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 In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ... has been severely reduced due to the large number of species introduced to the island when it was first settled in the 18th century.
