Laccosperma
''Laccosperma'' is a clustering genus of flowering plant in the family palm found in tropical Africa. Poorly studied and rarely cultivated, they are closely related to the genus '' Eremospatha'' and with it form a tribe in the ''Calameae'' characterized by dyads of hermaphrodite flowers.Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. / The genus name combines the Greek words for "reservoir" and "seed".Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / Description The trunks are mostly medium to large, clustering, high climbing, and extensively armed with sharp spines. The pinnate leaves are usually large, with spiny petioles, rachises and leaf sheaths. The barbed, linear leaflets are regularly arranged along the rachis and usually hang pendent.

Calamoideae
Calamoideae is a subfamily of flowering plant in the palm family found throughout Central America, South America, Africa, India, China, Southeast Asia and Australia. It is represented by 21 genera - containing nearly a quarter of all species in the palm family - including the largest genus, ''Calamus'', the type genus of the group. Only four are found in the New World while the rest are Old World denizens, usually found in equatorial swampland or along tropical coastlines. While the many species show marked differences, the bracts of all orders are tubular, the flowers are almost always borne in dyads or dyad derivatives, but most marked as an identifier among these palms are the overlapping scales covering the fruit; occasionally small and irregular they are, in most cases, neatly aligned in vertical rows. Also common to the group are varying forms of armament: spines along leaf margins or on sheaths, root and stem spines, reflexed rachis cirri, or specialized hooks among the ...

Laccosperma Secundiflorum
''Laccosperma secundiflorum'', the gao, is a species of palm found in the Dzangha-Sangha tropical forests of Cameroon. It has thorny stems, which it uses to wrap around nearby trees, enabling it to grow to heights of over 30 metres. The local population harvests the trees, and uses them to make palm oil and palm wine, as well as canes (similar to rattan Rattan, also spelled ratan, is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed-canopy old-growth tropical forests of ...) for furniture, mats and baskets. Calamoideae {{Palm-stub ...

Eremospatha
''Eremospatha'' is a genus of climbing flowering plants in the palm family found in tropical Africa. These rattans are uncommon in cultivation and poorly understood by taxonomists;. Closely related to ''Laccosperma'', they differentiated by the near complete absence of bracts and bracteoles.Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. / The name is from Greek meaning "without a spathe". Description The slender, high-climbing trunks are naturally clustering and can reach up to 45 m in length. The pinnate leaves range from 30 cm to 2.5 m on short, armed petioles; the rachis, leaf margins and cirri are also armed with spines. They are hermaphroditic, with both male and female reproductive organs present in each flower. The pale blooms are fragrant and produce a red to brown, scaly fruit, each containing one to three seeds.Riffle, Robert L. and Craft, Paul ( ...

Carl Georg Oscar Drude
Carl Georg Oscar Drude (5 June 1852 in Braunschweig – 1 February 1933 in Dresden) was a German botanist. From 1870 he studied science and chemistry at the Collegium Carolinum in Braunschweig, relocating to the University of Göttingen the following year, where he was influenced by August Grisebach (1814-1879). In 1873 he obtained his PhD and subsequently served as an assistant to Friedrich Gottlieb Bartling (1798-1875). From 1876 to 1879 he worked as a lecturer in botany at Göttingen, followed by an appointment as chair of botany at Dresden Technical University (1879). Here he served as director of its botanical gardens, which he systematically configured according to a phytogeographical principle. He remained at Dresden until his retirement in 1920, twice serving as university rector (1906-1907, 1918-1919). He is known best for his research in the field of plant geography, that included mapping of the world's different floristic zones. With Adolf Engler Heinrich Gus ...

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.

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 ...

Congo Basin
The Congo Basin (french: Bassin du Congo) is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity, many experts have characterized the basin's forest as important for mitigating climate change because of its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.
