Chailletia Toxicaria
''Dichapetalum cymosum'', commonly known as gifblaar from Afrikaans, or occasionally by its English translation, poison leaf, is a small prostrate shrub occurring in northern parts of Southern Africa in the family Dichapetalaceae. It is notable as a common cause of lethal cattle poisoning in this region and is considered one of the 'big 6' toxic plants of cattle in South Africa. A 1996 estimate of plant poisonings in South Africa attributes 8% of cattle mortality caused by poisonous plants to it. The majority (70%) of fatal cases are in Limpopo province, with 10% each in North West, Mpumalanga, and Gauteng. Fluoroacetate, the poison used to synthetically produce Compound 1080 used extensively in New Zealand, occurs in all parts of the plant and is responsible for the toxic effects shown. Toxic effects include vomiting, seizures, and an irregular heartbeat, and death can occur in as little as a few hours. This poison is known as “the poison that keeps on killing” because ...

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friendshi ...

South African Republic
The South African Republic ( nl, Zuid-Afrikaansche Republiek, abbreviated ZAR; af, Suid-Afrikaanse Republiek), also known as the Transvaal Republic, was an independent Boer Republic in Southern Africa which existed from 1852 to 1902, when it was annexed into the British Empire as a result of the Second Boer War. The ZAR was established as a result of the 1852 Sand River Convention, in which the Government of the United Kingdom, British government agreed to formally recognise independence of the Boers living north of the Vaal River. Relations between the ZAR and Britain started to deteriorate after the British Cape Colony expanded into the Southern African interior, eventually leading to the outbreak of the First Boer War between the two nations. The Boer victory confirmed the ZAR's independence; however, Anglo-ZAR tensions soon flared up again over various diplomatic issues. In 1899, war again broke out between Britain and the ZAR, which was swiftly occupied by the British mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musina
Musina (; formerly Messina) is the northernmost town in the Limpopo province of South Africa. It is located near the confluence of the Limpopo River with the Sand River and the border to Zimbabwe. It has a population of between 20,000 and 40,000. Iron ore, coal, magnetite, graphite, asbestos, diamonds, semi-precious stones and copper are mined in the region. History After serving in the Anglo-Boer War, Colonel John Pascoe "J.P." Grenfell (1866-1948), grandson of John Pascoe Grenfell and brother of Francis Octavius Grenfell, came to South Africa after hearing rumors of valuable copper being in the area. Two prospectors, James Harper and James Campbell, told Grenfell that there were copper deposits, south of the Limpopo River, where the local tribe discovered them. Apparently, the tribe had mined the copper, but the prospectors said their mining of it had ceased. Grenfell went to the area and had the deposits inspected. After verifying that they were valuable, he purchased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middelburg, Mpumalanga
Middelburg is a large farming and industrial town in the South African province of Mpumalanga. History It was initially established as a halfway station between Lydenburg and Pretoria by the Republic of Lydenburg in 1860. That republic would merge with the South African Republic (ZAR) soon afterwards. The proposed town was established on two farms, ''Klipfontein'' and ''Keerom'' but when the Dutch Reformed Church established a church next door on the farm ''Sterkfontein'', the town would be moved there. It was established as Nasareth, in 1864 by the Voortrekkers on the banks of the Klein Olifants River. It was changed in 1872 to Middelburg to mark its location between the Transvaal capital Pretoria, and the gold mining town of Lydenburg. The Dutch Reformed church was built in 1890. The British built a large concentration camp in Middelburg during the Second Boer War. The Memorial Museum was built at the site next to the 1,381 graves of women and children who died in the concentrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mmabatho
Mmabatho (Tswana for "Mother of the People") is the former capital of the North-West Province of South Africa. During the apartheid era, it was the capital of the former "Bantustan" of Bophuthatswana. Following the end of apartheid in 1994, Bophuthatswana was integrated into the newly established North-West Province and Mmabatho was proclaimed the provincial capital. However, Mmabatho's status as the provincial capital was short-lived. Later in 1994, the North West provincial legislature voted to rename the capital to Mahikeng (the town of Mafikeng having been merged with Mmabatho in 1980 and treated as a suburb of Mmabatho between 1980 and 1994), reducing Mmabatho to a suburb of Mafikeng. Mmabatho contains many provincial government buildings, a shopping complex called Mega City and a Sports Stadium formerly called the Independence Stadium. The North-West University, formerly the University of Bophuthatswana, is located in Mmabatho. Situated just south of the Botswana border, ...

Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the Canopy (forest), canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to ''Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly sp ...

Vangueria
''Vangueria'' is a genus of flowering plants in the family Rubiaceae. The genus is named for , as '' V. madagascariensis'' is known in Malagasy. Distribution The genus contains over 50 species distributed in Africa south of the Sahara with one species occurring in Madagascar ('' V. madagascariensis''). The centre of diversity is in East Africa (Kenya, Tanzania) and they are rare in West Africa. Bacterial leaf symbiosis Endophytic bacteria are housed in the intercellular space of the leaf mesophyll tissue. The presence of these bacteria can only be microscopically ascertained. The bacteria are identified as ''Burkholderia'', which is a genus that is also found in the leaves of other Rubiaceae species. The hypothesis is that these endophytic bacteria provide chemical protection against insect herbivory. Gousiekte Several ''Vangueria'' species - '' V. latifolia'', '' V. pygmaea'', '' V. thamnus'' - are known to cause , a cardiotoxicosis of ruminants characterised by heart failure ...

Rubiaceae
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include ''Coffea'', the source of coffee, '' Cinchona'', the source of the antimalarial alkaloid quinine, ornamental cultivars (''e.g.'', '' Gardenia'', ''Ixora'', ''Pentas''), and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, interpetiolar stipules, tubu ...

San People
The San peoples (also Saan), or Bushmen, are members of various Khoe, Tuu, or Kxʼa-speaking indigenous hunter-gatherer cultures that are the first cultures of Southern Africa, and whose territories span Botswana, Namibia, Angola, Zambia, Zimbabwe, Lesotho and South Africa. In 2017, Botswana was home to approximately 63,500 San people (roughly 2.8% of the population) making it the country with the highest number of San people. Definition The term "San" has a long vowel and is spelled Sān (in Khoekhoegowab orthography). It is a Khoekhoe exonym with the meaning of "foragers" and was often used in a derogatory manner to describe nomadic, foraging people. Based on observation of lifestyle, this term has been applied to speakers of three distinct language families living between the Okavango River in Botswana and Etosha National Park in northwestern Namibia, extending up into southern Angola; central peoples of most of Namibia and Botswana, extending into Zambia and Zimbabwe ...
