Prunus
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Botany Members of the genus can be deciduous or evergreen. A few species ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prunus Africana
''Prunus africana'', the African cherry, has a wide distribution in Africa, occurring in montane regions of central and southern Africa and on the islands of Bioko, São-Tomé, Grande Comore, and Madagascar. It can be found at above sea level. It is a canopy tree 30–40 m in height, and is the tallest member of ''Prunus''. Large-diameter trees have impressive, spreading crowns. It requires a moist climate, annual rainfall, and is moderately frost-tolerant. Previewable Google Books. ''P. africana'' appears to be a light-demanding, secondary-forest species. The bark is black to brown, corrugated or fissured, and scaly, fissuring in a characteristic rectangular pattern. The leaves are alternate, simple, long, elliptical, bluntly or acutely pointed, glabrous, and dark green above, pale green below, with mildly serrated margins. A central vein is depressed on top, prominent on the bottom. The petiole is pink or red. The flowers are androgynous, 10-20 stamens, insect-pollinated, , ...

Endemic Flora Of The Democratic Republic Of The Congo
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of The Democratic Republic Of The Congo
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
