Bulbophyllum Modicum
''Bulbophyllum modicum'' is a possibly extinct, epiphytic plant species in the family Orchidaceae. It is endemic to Cameroon, and its natural habitat (montane subtropical or tropical dry forests of Mount Cameroon between 900 and 1,200 meters in altitude) is threatened. It was described in 1957. All (3) confirmed collections of ''B. modicum'' come from the outskirts of the town of Buea. One other collection from Bambui (Bamenda) is sterile, and has yet to be confirmed as being this species. Possible threats to ''B. modicum'', if it is still extant, all arise from the intensive clearing of its forest habitat, whether for the purposes of obtaining firewood, the cultivation of crops, or the expansion of house-building.

Victor Samuel Summerhayes
Victor Samuel Summerhayes (21 February 1897 – 27 December 1974) was an English botanist in charge of the orchid herbarium at Royal Botanical Gardens, Kew for 39 years. Summerhayes was born on 21 February 1897 at Street, Somerset and he was educated at Sexey's School, Bruton and University College, London. His time at University was interrupted by World War I, when he served in the Royal Engineers including action at the Battle of the Somme The Battle of the Somme (French: Bataille de la Somme), also known as the Somme offensive, was a battle of the First World War fought by the armies of the British Empire and French Third Republic against the German Empire. It took place bet .... In 1920 after being awarded a first-class honours degree, he was awarded the Quain Studentship. Summerhayes started work at the Herbarium at Kew in 1924. Summerhayes retired from the Royal Botanical Gardens in 1964 and moved to Sidmouth where he lived until his death in 1974. Reference ...

Bambui
Bambui is an emerging township in northwestern Cameroon. With a population of about 17,000 people, it is located at an elevation of about 1350 metres above sea level. Administratively, Bambui is the headquarters of Tubah Sub-Division in the North West Region of Cameroon. Popularly known to its inhabitants as “abeh-mbeuh,” Bambui is one of the Bamenda grassfield communities of Cameroon, and is known for its mix of modern and indigenous African life. With its lush, rolling, and fertile plains, a mild tropical climate, and an extremely industrious farming community, Bambui is the bread basket of the North West Region in particular and of Cameroon in general. Lying snug in the immense arms of the Sabga hill, Bambui is situated between Sabga and the undulating foothills that separate it with its neighbors, virtually in the shape of a bowl. Bambui is located at the cross-roads that lead to some of the North West Region's major towns of Bamenda, Ndop, Kumbo, Fundong and Nkambé. W ...

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] |
Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3654 endangered plant species. 17% of all evaluated plant species are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of exintction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1957
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 abili ...

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] |
Crop
A crop is a plant that can be grown and harvested extensively for profit or subsistence. When the plants of the same kind are cultivated at one place on a large scale, it is called a crop. Most crops are cultivated in agriculture or hydroponics. Crops may include macroscopic fungus (e.g. mushrooms) and marine macroalga (e.g. seaweed), some of which are grown in aquaculture. Most crops are harvested as food for humans or fodder for livestock. Some crops are gathered from the wild often in a form of intensive gathering (e.g. ginseng, yohimbe, and eucommia). Important non-food crops include horticulture, floriculture and industrial crops. Horticulture crops include plants used for other crops (e.g. fruit trees). Floriculture crops include bedding plants, houseplants, flowering garden and pot plants, cut cultivated greens, and cut flowers. Industrial crops are produced for clothing (fiber crops e.g. cotton), biofuel (energy crops, algae fuel), or medicine (medic ...

Firewood
Firewood is any wooden material that is gathered and used for fuel. Generally, firewood is not highly processed and is in some sort of recognizable log or branch form, compared to other forms of wood fuel like pellets or chips. Firewood can be seasoned and heat treated (dry) or unseasoned (fresh/wet). It is generally classified as hardwood or softwood. Firewood is a renewable resource. However, demand for this fuel can outpace its ability to regenerate on a local or regional level. Good forestry practices and improvements in devices that use firewood can improve local wood supplies. Moving firewood long distances can potentially transport diseases and invasive species. History For most of human history firewood was the main fuel, until the use of coal spread during the Industrial Revolution. As such, access to firewood was a valued resource, wood botes or the right to gather firewood being a significant aspect of many medieval leases. As late as 19th C America, Th ...

Sterility (physiology)
Sterility is the physiological inability to effect sexual reproduction in a living thing, members of whose kind have been produced sexually. Sterility has a wide range of causes. It may be an inherited trait, as in the mule; or it may be acquired from the environment, for example through physical injury or disease, or by exposure to radiation. Sterility is the inability to produce a biological child, while infertility is the inability to conceive after a certain period. Sterility is rarely discussed in clinical literature and is often used synonymously with infertility. Infertility affects about 12-15% of couples globally. Still, the prevalence of sterility remains unknown. Sterility can be divided into three subtypes natural, clinical, and hardship. Natural sterility is the couple’s physiological inability to conceive a child naturally. Clinical sterility is natural sterility for which treatment of the patient will not result in conception. Hardship sterility is the inability t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamenda
Bamenda, also known as Abakwa and Mankon Town, is a city in northwestern Cameroon and capital of the Northwest Region. The city has a population of about 2 million people and is located north-west of the Cameroonian capital, Yaoundé. Bamenda is known for its cool climate and scenic hilly location. History Colonial era The origins of the city are related to the settlement of the Tikar people who culturally forged and maintained relations with the Kingdom of Bamum in the 1700s. In 1884, the city was colonized by Germany until 1916 when it became a colony administered by Great Britain and France. In 1919, the administration of Northwest Region and thus the city of Bamenda became only British. In 1961, the region joined the Cameroon. Ambazonian aspirations Many of the city's inhabitants are English-speaking, and Cameroonian Pidgin English is the main language spoken in the shops and on the streets of Bamenda. For over four years, there has been an insurgency due to political t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buea
Buea is the capital of the Southwest Region of Cameroon. The city is located in Fako Division, on the eastern slopes of Mount Cameroon, and has a population of 300,000 (at the 2013 Census). It has two Government Hotels, the Mountain Hotel and Parliamentarian Flats Hotel located around The Government Residential Area. The self-declared state of Ambazonia claims the city as its capital. History Buea, originally "bue", was founded by a hunter who came from the Bomboko area. Coming from the Bomboko side of the mountain, he named the new-found land in amazement as "a Bue", meaning literally a "son of bué". A prominent King of the tikar clashes with German troops during invasion. Resistance remain popular folklore; currently ruled by the Endeleys. Tea growing is an important local industry, especially in Tole. Buea was the colonial capital of German Kamerun from 1901 to 1919, the capital of the Southern Cameroons from 1949 until 1961 and the capital of West Cameroon until 197 ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew ( Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The ...
