Dacryodes Klaineana
''Dacryodes klaineana'' is an evergreen perennial tree within the Burseraceae The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of flowering plants. The actual numbers differ according to the time period in which a given source is written describing this family. The Burseraceae are also know ... family. It is locally called Monkey plum and African cherry fruit as a result of its edible pulp. Description The species is capable of growing up 25 meters tall and reaching 60 cm in diameter. Leaves, alternate arrangement, imparipinnately compound, between 2 - 4 pairs of leaflets per pinnae, younger trees tend to have more pairs of leaflets; petiole with a size range between 2.5 x 6.5 cm long, glabrous lamina. Leaf-blade: narrowly elliptic to narrowly ovate, 4.5 x 18 cm long and 2 x 6.5 cm wide, petiolules of the terminal leaflet slightly longer while those of the lower pairs slightly shorter than others and also with shorter leaf ...

Burseraceae
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of flowering plants. The actual numbers differ according to the time period in which a given source is written describing this family. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs, and is native to tropical regions of Africa, Asia. Australasia, and the Americas. Just as the family size (in terms of genera and species) differs according to the time period of the study, so, too, does its placement in the higher ranks. Nevertheless, the family is a genetically supported monophyletic group currently and frequently cited within the Sapindales and is recognized as a sister group to the Anacardiaceae. The Burseraceae are characterized by the nonallergenic resin they produce in virtually all plant tissue and the distinctive smooth, yet flaking, aromatic bark.Judd, W.S., Campbell, C.S., ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.

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] |
Flora Of Gabon
The wildlife of Gabon is composed of its flora and fauna. Gabon is a largely low-lying country with a warm, humid climate. Much of the country is still covered by tropical rainforest and there are also grasslands, savannas, large rivers and coastal lagoons. Overview Wildlife includes forest elephants, forest buffalos, various antelope and monkey species, sitatungas, leopards, three species of crocodiles, chimpanzees and gorillas, and several marine turtle species which nest along the coast. As of 2002, there were at least 190 species of mammals. Fauna Mammals Gabon has important populations of many mammals including about 35,000 gorillas, 50,000 forest elephants and 64,000 common chimpanzees. About a quarter of Africa's gorillas live in Gabon. Other large mammals include the hippopotamus, forest buffalo, bongo and red river hog. A variety of monkeys occur, including the endemic Sun-tailed monkey, and the near-endemic mandrill and white-collared managabey (here near-endemic me ...
