Bulbophyllum Bifarium
''Bulbophyllum bifarium'', or two-sided bulbophyllum, is an epiphytic (occasionally lithophytic) plant species in the family Orchidaceae, flowering in November and endemic to Cameroon. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests, where it is threatened by habitat loss. It was described in 1864 by Joseph Dalton Hooker. Range and habitat ''B. bifarium'' is found exclusively in the submontane and montane forests of Cameroon, at elevations between 800 and 1,800 meters, where it occupies a land area in excess of 2,000 square km. Sites where ''B. bifarium'' specimens have been collected include: along the Douala to Bimbia road; Mfongu near Bagangu; Bana-Bateha near Fibé; Nkokom Massif near Ndom; Nyasoso on Mount Kupe; Kodmin in the Bakossi Mountains; and on Mount Cameroon. It is likely that ''B. bifarium'' is already extinct in many of the lower-elevation areas within its traditional range. This ...

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified ...

Plants Described In 1864
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abil ...

Epiphytic Orchids
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Orchids Of Cameroon
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulbophyllum
''Bulbophyllum'' is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by ''Astragalus''. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from ''Dendrobium''. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate ''Bulbophyllum'' into smaller genera, but mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantation
A plantation is an agricultural estate, generally centered on a plantation house, meant for farming that specializes in cash crops, usually mainly planted with a single crop, with perhaps ancillary areas for vegetables for eating and so on. The crops that are grown include cotton, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use the term is usually taken to refer only to large-scale estates, but in earlier periods, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northwards. It was used in most British colonies, but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantatio ...

Farm
A farm (also called an agricultural holding) is an area of land that is devoted primarily to agricultural processes with the primary objective of producing food and other crops; it is the basic facility in food production. The name is used for specialized units such as arable farms, vegetable farms, fruit farms, dairy, pig and poultry farms, and land used for the production of natural fiber, biofuel and other commodities. It includes ranches, feedlots, orchards, plantations and estates, smallholdings and hobby farms, and includes the farmhouse and agricultural buildings as well as the land. In modern times the term has been extended so as to include such industrial operations as wind farms and fish farms, both of which can operate on land or sea. There are about 570 million farms in the world, most of which are small and family-operated. Small farms with a land area of fewer than 2 hectares operate about 1% of the world's agricultural land, and family farms comprise ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds ( taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Cameroon
Mount Cameroon is an active volcano in the South West region of Cameroon next to the city of Buea near the Gulf of Guinea. Mount Cameroon is also known as Cameroon Mountain or Fako (the name of the higher of its two peaks) or by its indigenous name ''Mongo ma Ndemi'' ("Mountain of Greatness"). It is the highest point in sub-Saharan western and central Africa, the fourth-most prominent peak in Africa, and the 31st-most prominent in the world. The mountain is part of the area of volcanic activity known as the Cameroon Volcanic Line, which also includes Lake Nyos, the site of a disaster in 1986. The most recent eruption occurred on February 3, 2012. Description Mount Cameroon is one of Africa's largest volcanoes, rising to above the coast of west Cameroon. It rises from the coast through tropical rainforest to a bare summit, which is cold, windy, and occasionally dusted with snow. The massive steep-sided volcano of dominantly basaltic-to-trachybasaltic composition forms a vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bakossi Mountains
The Bakossi Mountains are a mountain range that forms part of the Cameroon line of active and extinct volcanoes in western Cameroon, covering about . The mountains lie in the regions of Littoral and the Southwest. The highest peak in this range is Mount Kupe at . They contain a large area of cloud forest, and have considerable ecological interest. The mountains are home to the Bakossi people The Bakossi people are a Bantu ethnic group that live on the western and eastern slopes of Mount Mwanenguba and Mount Kupe in the Bakossi Mountains of Cameroon. They number about 200,000, mostly engaged in subsistence farming but also producing .... The climate is tropical, with rainfall throughout the year. The drier season lasts from November to March, with cold nights and hot days. The rainy season starts in April and peaks between late August and the end of October. The soil is fertile, supporting coffee and cocoa as cash crops. The mountains hold the Bakossi Forest Reserve, a rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
