Terminalia Bentii
''Terminalia bentii'' is a species of plant in the Combretaceae family. It is endemic to the fog woodlands of Yemen. The species was first described as ''Anogeissus bentii'' by John Gilbert Baker in 1895. In 2017 the genus ''Anogeissus'' was made a synonym of ''Terminalia Terminalia may refer to: * Terminalia (festival) Terminalia () was an ancient Roman festival in honour of the god Terminus, who presided over boundaries. His statue was merely a stone or post stuck in the ground to distinguish between propert ...'', and the species was renamed ''Terminalia bentii''.

John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an England, English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899. He wrote handbooks on many plant groups, including Amaryllidaceae, Bromeliaceae, Iridaceae, Liliaceae, and ferns. His published works includ''Flora of Mauritius and the Seychelles''(1877) and ''Handbook of the Irideae'' (1892). Baker issued several exsiccata-like series, among others the series ''Herbarium of British Roses [Herbarium Rosarum Britannicarum]''.Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. – Botanische Staatssammlung München: http://in ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Combretaceae
The Combretaceae, often called the white mangrove family, are a family of flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed with ...s in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in 10 genera. The family includes the leadwood tree, '' Combretum imberbe''. Three genera, '' Conocarpus'', '' Laguncularia'', and '' Lumnitzera'', grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from '' Terminalia ivorensis''. The commonly cultivated '' Quisqualis indica'' (as well as the entire former genus ''Quisqualis'') is now placed in the genus '' Combretum''. Many plants in the former ''Quisqualis'' genus contain t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

South Arabian Fog Woodlands, Shrublands, And Dune
The South Arabian fog woodlands, shrublands, and dune is an ecoregion in Oman and Yemen. The fog woodlands lie on mountainsides which slope southeastwards towards the Arabian Sea. The mountains intercept moisture-bearing winds from the Arabian Sea, creating orographic precipitation and frequent fogs that sustain unique woodlands and shrublands in a desert region. Geography The ecoregion occupies an area of in eastern Yemen and southern Oman's Dhofar Governorate. The ecoregion covers four separate areas. The westernmost is the Ureys (or Areys) range, a coastal mountain range that rises east of the town of Shuqrah, 150 kilometres northeast of Aden. The range is made up of dark igneous rock, extending about 65 kilometres east and west parallel to the coast. It is named for its tallest peak, Jabal Ureys (1,735 metres), which lies at the western end of the range close to the coast. The rest of the range is an east–west ridge 1,500 to 1,600 metres high, dropping to a dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terminalia (plant)
''Terminalia'' is a genus of large trees of the flowering plant family Combretaceae, comprising nearly 300 species distributed in Tropics, tropical regions of the world. The genus name derives from the Latin word ''terminus'', referring to the fact that the leaves appear at the very tips of the shoots. Terminalia latifolia, Axlewood (''T. latifolia'') is used for its wood and tannins and as a fodder. Terminalia leiocarpa, African birch (''T. leiocarpa'') is used for its wood and to make yellow dye and medicinal compounds. A yellow dyestuff produced from the leaves of ''T. leiocarpa'' has traditionally been used in West Africa to dye leather. Selected species There are 278 accepted ''Terminalia'' species as of July 2024 according to Plants of the World Online. Selected species include: *''Terminalia acuminata'' (Fr. Allem.) Eichl. *''Terminalia albida'' Scott-Elliot *''Terminalia amazonia'' (J.F.Gmel.) Exell – white olive *''Terminalia anogeissiana'' – axlew ...

Endangered Plants
In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. Of all evaluated plant species, 17% 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 extinction". 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, they are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...
