Entandrophragma Caudatum
''Entandrophragma caudatum'', or mountain mahogany, is a large Southern African tree belonging to the Meliaceae, mahogany family and found in eastern and north eastern South Africa, Eswatini, Botswana, Angola, the Caprivi Strip region of Namibia, Zimbabwe, Zambia and Malawi. Royal Botanic Gardens, Kew, Kew currently recognises 12 other species of Entandrophragma, all with a tropical and sub-tropical African distribution. This is a large deciduous tree up to 20m in height, found at low altitudes in river valleys, but also in open woodland on rocky slopes and ridges. Bark is grey, flaking in large, irregular scales and revealing a buff surface, giving a mottled appearance. The leaves up to 25 cm long, puberulous, crowded near the ends of branches, paripinnately compound with 6 or 7 pairs of leaflets, each leaflet measuring up to 11 x 3.5 cm. The leaflets are hairless with a narrowly attenuate apex or drip-tip, and entire margin. Petioles are some 20mm in length and slend ...

Entandrophragma Angolense
''Entandrophragma angolense'', called the ''tiama'', is a tree species with alternate, pinnately compound leaves that are clustered at the ends of branches. It is within the family Meliaceae and has a wide distribution area, occurring in moist semi-deciduous and evergreen forest regions of Tropical Africa from Sierra Leone to Uganda. Harvesting for timber has caused the species to become vulnerable in certain countries. Taxonomy ''Entandrophragma angolense'' was first indicated as belonging to the Swietenia family but upon a revision in 1894 by de Candolle, the species was transferred to a new genus Entandrophragma. In 2021, up to 10 taxa are placed as synonyms of the species in two database. Description The tree can grow to a height of 60 meters and reach a diameter of 200 cm, its base often has developed buttresses that can reach a height of 6 meters, and extending as surface roots, the trunk is branchless for up to 30 meters. The grey-brown bark tends to be thin and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entandrophragma Cylindricum
''Entandrophragma cylindricum'' is a tree of the genus ''Entandrophragma'' of the family ''Meliaceae''. It is commonly known as sapele or sapelli ( ) or sapele mahogany, as well as aboudikro, assi, and muyovu. Origin of the name The name ''sapele'' comes from that of the city of Sapele in Nigeria, where there is a preponderance of the tree. African Timber and Plywood (AT&P), a division of the United Africa Company, had a factory at this location where the wood, along with ''Triplochiton scleroxylon'', ''Obeche'', mahogany, and Khaya was processed into timber which was then exported from the Port of Sapele worldwide. The name of the city itself is said to be an anglicisation of the Urhobo word Uriapele, commemorating a local deity. It is believed the British colonial authorities changed the name of the then hamlet to Sapele as it was easier to pronounce. Description ''Entandrophragma cylindricum'' is native to tropical Africa. There are protected populations and felling restr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus (''Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilimanjaro
Mount Kilimanjaro () is a dormant volcano in Tanzania. It has three volcanic cones: Kibo, Mawenzi, and Shira. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world: above sea level and about above its plateau base. It is the highest volcano in Africa and the Eastern Hemisphere. Kilimanjaro is the fourth most topographically prominent peak on Earth. It is part of Kilimanjaro National Park and is a major hiking and climbing destination. Because of its shrinking glaciers and ice fields, which are projected to disappear between 2025 and 2035, it has been the subject of many scientific studies. Toponymy The origin of the name Kilimanjaro is not known, but a number of theories exist. European explorers had adopted the name by 1860 and reported that Kilimanjaro was the mountain's Kiswahili name. The 1907 edition of ''The Nuttall Encyclopædia'' also records the name of the mountain as Kilima-Njaro. Johann Ludwig Krapf ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
