Pink Ivory
Pink ivory (''Phyllogeiton zeyheri'', syn. ''Berchemia zeyheri''), also called purple ivory, red ivory, umnini or umgoloty, is an African hardwood used to make a variety of products (for example: billiard cues and knife handles). The pink ivory tree grows predominantly in Zimbabwe, Mozambique, Northern Botswana and South Africa. The tree is protected and sustainably maintained in South Africa, only felled by very limited permit. The wood is extremely hard, with a density of 990 g/dm3. Pink ivory was the royal tree of the Zulu people and only members of the royal family were allowed to possess it until the Anglo-Zulu War The Anglo-Zulu War was fought in 1879 between the British Empire and the Zulu Kingdom. Following the passing of the British North America Act of 1867 forming a federation in Canada, Lord Carnarvon thought that a similar political effort, coupl ... of 1879. Before the Anglo-Zulu War, the Zulu king (and prior to 1818, Zulu chiefs) would possess a pink ivory ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Wilhelm Sonder
Otto Wilhelm Sonder (18 June 1812, Bad Oldesloe – 21 November 1881) was a German botanist and pharmacist. Life A native of Holstein, Sonder studied at Kiel University, where he sat pharmaceutical examinations in 1835, before becoming the proprietor of a pharmacy in Hamburg from 1841 to 1878. In 1846 he received an honorary doctorate from the University of Königsberg and was elected a member of the German National Academy of Sciences Leopoldina for his contribution to the field of botany. Herbarium From a young age, Sonder showed considerable interest and skill in Botany. He often embarked on botanical excursions in his local area early in the morning before heading to work at the pharmacy. Throughout his life, Sonder met and conversed with many eminent botanists of the era. He amassed an extensive botanical collection that contained hundreds of thousands of specimens representing all major plant groups and spanning all parts of the globe. The collection is particularly sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglo-Zulu War
The Anglo-Zulu War was fought in 1879 between the British Empire and the Zulu Kingdom. Following the passing of the British North America Act of 1867 forming a federation in Canada, Lord Carnarvon thought that a similar political effort, coupled with military campaigns, might succeed with the African Kingdoms, tribal areas and Boer republics in South Africa. In 1874, Sir Bartle Frere was sent to South Africa as High Commissioner for the British Empire to effect such plans. Among the obstacles were the armed independent states of the South African Republic and the Kingdom of Zululand.Knight (1992, 2002), p. 8. Frere, on his own initiative, sent a provocative ultimatum on 11 December 1878 to the Zulu king Cetshwayo and upon its rejection sent Lord Chelmsford to invade Zululand. The war is notable for several particularly bloody battles, including an opening victory of the Zulu at the Battle of Isandlwana, followed by the defence of Rorke's Drift by a small British force from ...

Flora Of Zimbabwe
The wildlife of Zimbabwe occurs foremost in remote or rugged terrain, in national parks and private wildlife ranches, in miombo woodlands and thorny acacia or kopje. The prominent wild fauna includes African buffalo, African bush elephant, black rhinoceros, southern giraffe, African leopard, lion, plains zebra, and several antelope species. The introduction of the Wildlife Conservation Act of 1960 resulted in checking the loss of wildlife in Zimbabwe, since the 1960s. In the 1990s, it became one of the leading countries in Africa in wildlife conservation and management with a reported income generation US$300 million per year from the protected areas of the state, rural community run wildlife management areas and private game ranches and reserves. The Parks and Wildlife Board consisting of 12 members is responsible for this activity and deciding on policy issues under the Ministry of Environment and Natural Resources Management.

Trees Of South Africa
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhamnaceae
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. ''Paliurus spina-christi'' and '' Colletia cruciata'') spectacularly so. ''Colletia'' stands out by having two axillary buds instead of one, one developing int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drupe
In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or '' pyrena'') of hardened endocarp with a seed (''kernel'') inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, lignified stone is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a different definition of ''berry''. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes. Flowering plants that produce drupes include coffee, jujube, mango, oli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zulu Kingdom
The Zulu Kingdom (, ), sometimes referred to as the Zulu Empire or the Kingdom of Zululand, was a monarchy in Southern Africa. During the 1810s, Shaka established a modern standing army that consolidated rival clans and built a large following which ruled a wide expanse of Southern Africa that extended along the coast of the Indian Ocean from the Tugela River in the south to the Pongola River in the north. A bitter civil war in the mid-19th century erupted which culminated in the 1859 Battle of Ndondakusuka between the brothers Cetshwayo and Mbuyazi. In 1879, a British force invaded Zululand, beginning the Anglo-Zulu War. After an initial Zulu victory at the Battle of Isandlwana in January, the British regrouped and defeated the Zulus in July during the Battle of Ulundi, ending the war. The area was absorbed into the Colony of Natal and later became part of the Union of South Africa. History Rise under Shaka Shaka was the illegitimate son of Senzangakhona, Chief of the ...

Knobkerrie
A knobkerrie, also spelled knobkerry, knobkierie, and knopkierie (Afrikaans), is a form of wooden club, used mainly in Southern and Eastern Africa. Typically they have a large knob at one end and can be used for throwing at animals in hunting or for clubbing an enemy's head. For the various peoples who use them, they often have marked cultural significance. Being able to carry the knobkerrie has also had a political dimension, especially in South Africa. Name The name derives from the Afrikaans word ''knop'', meaning ''knob'' or ''ball'' and the Khoekhoe or San word ''kirri'', meaning walking stick. The name has been extended to similar weapons used by the native peoples of Australia, the Pacific islands and other places, and was also used in the British army. Uses in southern Africa and abroad Knobkerries were an indispensable weapon of war both in Africa and abroad. In Africa, the weapon found particular use among Nguni peoples. Among the Zulu people they are known as ''i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zulu People
Zulu people (; zu, amaZulu) are a Nguni ethnic group native to Southern Africa. The Zulu people are the largest ethnic group and nation in South Africa, with an estimated 10–12 million people, living mainly in the province of KwaZulu-Natal. They originated from Nguni communities who took part in the Bantu migrations over millennia. As the clans integrated together, the rulership of Shaka brought success to the Zulu nation due to his improved military tactics and organization. Zulus take pride in their ceremonies such as the Umhlanga, or Reed Dance, and their various forms of beadwork. The art and skill of beadwork takes part in the identification of Zulu people and acts as a form of communication and dedication to the tribe and specific traditions. The men and women both serve different purposes in society in order to function as a whole. Today the Zulu people predominantly believe in Christianity, but have created a syncretic religion that is combined with the Zulu's pr ...

Density
Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ''ρ'' (the lower case Greek letter rho), although the Latin letter ''D'' can also be used. Mathematically, density is defined as mass divided by volume: : \rho = \frac where ''ρ'' is the density, ''m'' is the mass, and ''V'' is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight. For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure. To simplify comparisons of density across different s ...
