Combretum Imberbe
''Combretum imberbe'' (leadwood, af, hardekool, st, mohwelere-tšhipi, ts, motswiri/mondzo, zu, impondondlovu) is a characteristic and often impressive bushwillow species of the southern Afrotropics. The medium to large tree has a sparse, semi-deciduous canopy of grey-green leaves. The twigs and leaves are hairless as the name ''imberbe'' suggests. Its heartwood is dark brown, close-grained, and very hard and heavy, as suggested by its vernacular name. The durable heartwood is much sought after in the woodcarving industry. The Hereros and Ovambos of Namibia attach special cultural and religious significance to the tree, as to them it is the great ancestor of all animals and people, which must be passed with respect. Range It is native to the mesic savannas of Africa south of the equator, from KwaZulu-Natal province, South Africa, in the south to Tanzania in the north. It is a native tree in South Africa, eSwatini, Botswana, Namibia, Zimbabwe, Mozambique, Angola, Zambia a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Wawra Von Fernsee
Heinrich Wawra Ritter von Fernsee, born Jindřich Blažej Vávra, (February 2, 1831 in Brno, Moravia – May 1887 in Baden bei Wien) was a Czech-Austrian ship surgeon, botanist and explorer. The youngest of five sons of a miller, he studied medicine and botany at the University of Vienna from 1849 to 1855. Upon graduating he joined the Austro-Hungarian Imperial Navy on December 6, 1855. The commander of the fleet at this time was the Archduke Ferdinand Maximilian. Wawra von Fernsee retired from the navy in 1878 to work on his extensive collections. The plant genus '' Fernseea'' was named after him.Genaust, Helmut (1976).

Trees Of Southern Africa
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), 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 Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos are also trees. Trees are not a Taxon, taxonomic group but include a variety of plant species that Convergent evolution, 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 ...

Flora Of Tanzania
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Mozambique
The wildlife of Mozambique consists of the flora and fauna of this country in southeastern Africa. Mozambique has a range of different habitat types and an ecologically rich and diverse wildlife. This includes 236 species of mammal, 740 species of bird and 5,692 species of vascular plant. The Maputaland-Pondoland-Albany hotspot, with significantly high levels of biodiversity, stretches from the southern tip of Mozambique into northeastern South Africa. Geography Mozambique is located on the southeast coast of Africa. It is bounded by Eswatini to the south, South Africa to the south and southwest, Zimbabwe to the west, Zambia and Malawi to the northwest, Tanzania to the north and the Indian Ocean to the east. Mozambique lies between latitudes 10° and 27°S, and longitudes 30° and 41°E. The country is divided into two topographical regions by the Zambezi River. To the north of the Zambezi, the narrow coastal strip gives way to inland hills and low plateaus. Rugged highland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toothpaste
Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be toxic. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. Usefulness Toothpastes are generally useful to maintain dental health. Toothpastes containing fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kraal
Kraal (also spelled ''craal'' or ''kraul'') is an Afrikaans and Dutch word, also used in South African English, for an enclosure for cattle or other livestock, located within a Southern African settlement or village surrounded by a fence of thorn-bush branches, a palisade, mud wall, or other fencing, roughly circular in form. It is similar to a '' boma'' in eastern or central Africa. In Curaçao, another Dutch colony, the enclosure was called "koraal" which in Papiamentu is translated "kura" (still in use today for any enclosed terrain, like a garden). Etymology In the Afrikaans language a ''kraal'' is a term derived from the Portuguese word , cognate with the Spanish-language , which entered into English separately. In Eastern and Central Africa, the equivalent word for a livestock enclosure is '' boma'', but this has taken on wider meanings. In some Southern African regions, the term Kraal is used in Scouting to refer to the team of Scout Leaders of a group. Homestead Th ...

Whitewash
Whitewash, or calcimine, kalsomine, calsomine, or lime paint is a type of paint made from slaked lime ( calcium hydroxide, Ca(OH)2) or chalk calcium carbonate, (CaCO3), sometimes known as "whiting". Various other additives are sometimes used. Use as paint Whitewash cures through a reaction with carbon dioxide in the atmosphere to form calcium carbonate in the form of calcite, a type of reaction generally known as carbonation or by the more specific term, carbonatation. It is usually applied to exteriors; however, it has been traditionally used in interiors of food preparation areas, particularly rural dairies, because of its mildly antibacterial properties. Whitewash can be tinted for decorative use and is sometimes painted inside structures such as the hallways of apartment buildings. However it can rub off onto clothing to a small degree. In Britain and Ireland, whitewash was used historically in interiors and exteriors of workers' cottages and still retains something o ...

Barbecue
Barbecue or barbeque (informally BBQ in the UK, US, and Canada, barbie in Australia and braai in South Africa) is a term used with significant regional and national variations to describe various cooking methods that use live fire and smoke to cook the food. The term is also generally applied to the devices associated with those methods, the broader cuisines that these methods produce, and the meals or gatherings at which this style of food is cooked and served. The cooking methods associated with barbecuing vary significantly but most involve outdoor cooking. The various regional variations of barbecue can be broadly categorized into those methods which use direct and those which use indirect heating. Indirect barbecues are associated with North American cuisine, in which meat is heated by roasting or smoking over wood or charcoal. These methods of barbecue involve cooking using smoke at low temperatures and long cooking times, for several hours. Elsewhere, barbecuing more co ...

Rail Tracks
A railway track (British English and UIC terminology) or railroad track (American English), also known as permanent way or simply track, is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton Wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of around 50 wooden-railed tramways built over the next 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed around the s ...

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...
