Parkia Clappertoniana
''Parkia biglobosa'', known in English as the African locust bean, is a perennial deciduous tree in the family Fabaceae. It is found in a wide range of environments in Africa and is primarily grown for its pods that contain both a sweet pulp and valuable seeds. Where the tree is grown, the crushing and fermenting of these seeds constitutes an important economic activity. Various parts of the locust bean tree are used for medicinal and food purposes. As a standing tree, locust bean may have a positive effect on the yield of other nearby crops. Description ''Parkia biglobosa'' is a dicotyledonous angiosperm belonging to the family Fabaceae (Caesalpinioideae - Mimosoid clade). It is categorized under spermatophytes, vascular plants. It is a deciduous perennial that grows to between 7 and 20 metres high, in some cases up to 30 metres.Ntui, V. O., Uyoh, E. A., Urua, I. S., Ogbu, U., & Okpako, E. C. (2012).

Nikolaus Joseph Von Jacquin
Nikolaus Joseph Freiherr von Jacquin (16 February 172726 October 1817) was a scientist who studied medicine, chemistry and botany. Biography Born in Leiden in the Netherlands, he studied medicine at Leiden University, then moved first to Paris and afterward to Vienna. In 1752, he studied under Gerard van Swieten in Vienna. Between 1755 and 1759, Jacquin was sent to the West Indies, Central America, Venezuela and New Granada by Francis I to collect plants for the Schönbrunn Palace, and amassed a large collection of animal, plant and mineral samples. In 1797, Alexander von Humboldt profited from studying these collections and conversing with Jacquin in preparation of his own journey to the Americas. In 1763, Jacquin became professor of chemistry and mineralogy at the Bergakademie Schemnitz (now Banská Štiavnica in Slovakia). In 1768, he was appointed Professor of Botany and Chemistry and became director of the botanical gardens of the University of Vienna. For his work ...

Yoruba People
The Yoruba people (, , ) are a West African ethnic group that mainly inhabit parts of Nigeria, Benin, and Togo. The areas of these countries primarily inhabited by Yoruba are often collectively referred to as Yorubaland. The Yoruba constitute more than 42 million people in Africa, are a few hundred thousand outside the continent, and bear further representation among members of the African diaspora. The vast majority of the Yoruba population is today within the country of Nigeria, where they make up 21% of the country's population according to CIA estimations, making them one of the largest List of ethnic groups of Africa, ethnic groups in Africa. Most Yoruba people speak the Yoruba language, which is the Niger–Congo languages, Niger-Congo language with the largest number of native or L1 speakers. In Africa, the Yoruba are contiguous with the Yoruboid languages, Yoruboid Itsekiri to the south-east in the northwest Niger Delta, Bariba people, Bariba to the northwest in Benin a ...

Flora Of Chad
The wildlife of Chad is composed of its flora and fauna. Bush elephants, West African lions, buffalo, hippopotamuses, Kordofan giraffes, antelopes, African leopards, cheetahs, hyenas, and many species of snakes are found there, although most large carnivore populations have been drastically reduced since the early 20th century. Elephant poaching, particularly in the south of the country in areas such as Zakouma National Park, is a severe problem. Vegetation As of 2011, there were 2,288 species in the country in the country, 55 of which are endemic. Precipitation varies widely from south to north of the country. The country is also subject to hot, dry, dusty conditions. Harmattan Winds are a feature in the northern part of the country. Droughts and locust plagues are also common. The vegetation in the country is broadly categorized under the three regions of the northern Sahara zone, the central Sahel zone, and the southern Sudan zone; all three zones are of equal proportion. ...

Flora Of West Tropical Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruits Originating In Africa
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banana
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus ''Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – ''Musa acuminata'' and ''Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ''Musa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tiv People
Tiv (or Tiiv) are a Tivoid ethnic group. They constitute approximately 2.4% of Nigeria's total population, and number over 5 million individuals throughout Nigeria and Cameroon. The Tiv language is spoken by about 5 million people in Nigeria with a few speakers in Cameroon. Most of the language's Nigerian speakers are found in Benue, Taraba, Nasarawa, Plateau, Cross rivers, Adamawa, Kaduna, and Abuja States. The language is a branch of Benue–Congo and ultimately of the Niger–Congo phylum. In pre-colonial times, the Fulani ethnic group referred to the Tiv as "Munchi" (also sometimes written Munshi e.g. Duggan 1932 and Ako 1981), a term not accepted by Tiv people. They depend on agricultural produce for commerce and life. History The Tiv believe they emerged into their present location from the southeast. It is claimed that the Tiv wandered through southern, south-central and west-central Africa before arriving at the savannah lands of West African Sudan via the ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Igbo People
The Igbo people ( , ; also spelled Ibo" and formerly also ''Iboe'', ''Ebo'', ''Eboe'', * * * ''Eboans'', ''Heebo''; natively ) are an ethnic group in Nigeria. They are primarily found in Abia, Anambra, Ebonyi, Enugu, and Imo States. A sizable Igbo population is also found in Delta and Rivers States. Large ethnic Igbo populations are found in Cameroon, Gabon, and Equatorial Guinea, as well as outside Africa. There has been much speculation about the origins of the Igbo people, which are largely unknown. Geographically, the Igbo homeland is divided into two unequal sections by the Niger River—an eastern (which is the larger of the two) and a western section. The Igbo people are one of the largest ethnic groups in Africa. The Igbo language is part of the Niger-Congo language family. Its regional dialects are somewhat mutually intelligible amidst the larger "Igboid" cluster. The Igbo homeland straddles the lower Niger River, east and south of the Edoid and Idomoid gr ...
