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, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ronald William John Keay
Ronald William John Keay (20 May 1920 – 7 April 1998) was a British botanist, who did much of his work in tropical Africa. Keay was educated at the University of Oxford. He was an expert in West African forest flora working at the Royal Botanic Gardens, Kew, and at the Forest Herbarium Ibadan (FHI), part of the Forestry Research Institute of Nigeria (FRIN), and was director of that institute from 1960 to 1962. He collected specimens in Rhodesia, Nigeria, West Cameroon, the Congo, Rhodesia and Zambia. During the 1970s and '80s he was a member, council member, treasurer and vice president of the Royal Society. After his retirement from the Royal Society he served as president of the Institute of Biology and also the treasurer of the Linnean Society of London.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Annonaceae
The Annonaceae are a Family (biology), family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably ''Annona'', ''Anonidium'', ''Asimina'', ''Rollinia'', and ''Uvaria''. Its type genus is ''Annona''. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan. Description The species are mostly tropical, some are mid-latitude, deciduous or evergreen trees and shrubs, with some lianas, with aromatic bark, leaves, and flowers. ; Stems, stalks and leaves: Bark is fibrous and aromatic. Pith septate (fine tangential bands divided by partitions) to diaphragmed (divided by thin partitions with openings in them). Branching distichous (arranged in two ...

Ghana
Ghana (; tw, Gaana, ee, Gana), officially the Republic of Ghana, is a country in West Africa. It abuts the Gulf of Guinea and the Atlantic Ocean to the south, sharing borders with Ivory Coast in the west, Burkina Faso in the north, and Togo in the east.Jackson, John G. (2001) ''Introduction to African Civilizations'', Citadel Press, p. 201, . Ghana covers an area of , spanning diverse biomes that range from coastal savannas to tropical rainforests. With nearly 31 million inhabitants (according to 2021 census), Ghana is the List of African countries by population, second-most populous country in West Africa, after Nigeria. The capital and List of cities in Ghana, largest city is Accra; other major cities are Kumasi, Tamale, Ghana, Tamale, and Sekondi-Takoradi. The first permanent state in present-day Ghana was the Bono state of the 11th century. Numerous kingdoms and empires emerged over the centuries, of which the most powerful were the Kingdom of Dagbon in the north and ...

Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to Liberia–Sierra Leone border, its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia.

Uvaria
''Uvaria'' is a genus of flowering plants in the family Annonaceae. The generic name ''uvaria'' is derived from the Latin ''uva'' meaning grape, likely because the edible fruit of some species in the genus resemble grapes. Circumscription Species are distributed throughout the Old World tropics.''Uvaria''. Flora of China. This large genus had about 150 species, but recent molecular analyses have revealed that several smaller genera belong within ''Uvaria'', increasing its size. These are climbing shrubs or small trees. The flowers are borne singly, in pairs, or in small clusters. There are six petals in two whorls and many stamens. Selected species There are 168 accepted ''Uvaria'' species, as of April 2021, according to |
Isolona
''Isolona'' is a genus of flowering plants in the family Annonaceae. There are 21 species native to Africa. They occur in humid habitat types.Couvreur, T. L., Gereau, R. E., Wieringa, J.

Flora Of Ghana
The wildlife of Ghana is composed of its biodiversity of flora and fauna. Biodiversity Fungi Ghana is home to a significant number of fungi species including: ''Aspergillus flavus''; ''Athelia rolfsii''; ''Auricularia auricula-judae''; ''Curvularia''; ''Fusarium oxysporum''; ''Fusarium solani'' f.sp. ''pisi''; '' Gibberella intricans''; ''Gibberella stilboides''; and ''Macrophomina phaseolina''. The true total number of fungal species occurring in Ghana is in the thousands and given the generally accepted estimate that only about 7 percent of all fungi worldwide have so far been discovered and that the amount of available information is still very small. Flora The flora of Ghana is diverse with both indigenous and introduced floral species considered in Ghana's floral diversity. A total of some 3,600 species of the major regional centres of endemism represent the three major taxonomic groups. Floral diversity is more pronounced among the angiosperms represented with well over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Liberia
The wildlife of Liberia consists of the flora and fauna of the Republic of Liberia. This West African nation has a long Atlantic coastline and a range of habitat types, with a corresponding diversity of plants and animals. Liberia is considered a biodiversity hotspot and has more intact forests characteristic of the Upper Guinea Massif than do neighbouring countries. There are 2000 species of vascular plants (including 225 tree species), approximately 140 species of mammals, and over 600 species of birds. Geography The country lies close to the equator with a long coastline on the Atlantic Ocean. The terrain consists of flat or undulating coastal plains, which rise to a rolling plateau and low mountains in the northeast. A number of short rivers flow from northeast to southwest. The coastal area is characterised by swamps and mangrove forests, while inland the tropical forests give way to grassland on the drier plateau area. The climate is equatorial with some rain all year roun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
