Rothmannia Capensis
''Rothmannia capensis'' is a South African tree belonging to the Rubiaceae, usually about 5 m high in the open, but reaching 20 m under forest conditions. It occurs from the south-western Cape Province along the coastal regions and inland to the Waterberg and Soutpansberg in the Transvaal. It is a common tree on the Witwatersrand in Johannesburg. It produces abundant sweetly fragrant flowers in summer, and these are followed by smooth, dark green spherical fruits about 80mm in diameter. The blackish bark has a distinctive rectangular pattern of fine cracks. The genus was named for Göran Rothman Göran (Georg) Rothman (30 November 1739, in Husebybruk, Småland, Sweden – 3 December 1778, in Stockholm), was a Swedish naturalist, physician and an apostle of Carl Linnaeus.

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

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 ...

Cape Province
The Province of the Cape of Good Hope ( af, Provinsie Kaap die Goeie Hoop), commonly referred to as the Cape Province ( af, Kaapprovinsie) and colloquially as The Cape ( af, Die Kaap), was a province in the Union of South Africa and subsequently the Republic of South Africa. It encompassed the old Cape Colony, as well as Walvis Bay, and had Cape Town as its capital. In 1994, the Cape Province was divided into the new Eastern Cape, Northern Cape and Western Cape provinces, along with part of the North West. History When the Union of South Africa was formed in 1910, the original Cape Colony was renamed the Cape Province. It was by far the largest of South Africa's four provinces, as it contained regions it had previously annexed, such as British Bechuanaland (not to be confused with the Bechuanaland Protectorate, now Botswana), Griqualand East (the area around Kokstad) and Griqualand West (area around Kimberley). As a result, it encompassed two-thirds of South Africa's terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterberg Biosphere
The Waterberg ( nso, Thaba Meetse) is a mountainous massif of approximately in north Limpopo Province, South Africa. The average height of the mountain range is 600 m with a few peaks rising up to 2000 m above sea level. Vaalwater town is located just north of the mountain range. The extensive rock formation was shaped by hundreds of millions of years of riverine erosion to yield diverse bluff and butte landform.C. Michael Hogan, Mark L. Cooke and Helen Murray, ''The Waterberg Biosphere'', Lumina Technologies, 22 May 2006. The ecosystem can be characterised as a dry deciduous forest or Bushveld. Within the Waterberg there are archaeological finds dating to the Stone Age, and nearby are early evolutionary finds related to the origin of humans. Waterberg (Thaba Meetse) is the first region in the northern part of South Africa to be named as a Biosphere Reserve by UNESCO.

Soutpansberg
The Soutpansberg, (formerly ''Zoutpansberg'') meaning "Salt Pan Mountain" in Afrikaans, is a Mountain range, range of mountains in far northern South Africa. It is located in Vhembe District Municipality, Vhembe District, Limpopo. It is named for the Salt pan (geology), salt pan ( ve, Thavha ya muno, or "place of salt") located at its western end. The mountain range reaches the opposite extremity in the Matikwa Nature Reserve, some due east. The range as a whole had no Venda language, Venda name, as it was instead known by its sub-ranges which include Dzanani, Hanglip, Songozwi and others. Of late it is however known as Tha vhani ya muno, meaning "mountain of salt". The Soutpansberg forms part of the 'Vhembe Biosphere Reserve', which was designated as a biosphere reserve by UNESCO in 2009. The latter reserve also includes the Blouberg Range, Kruger National Park, Makgabeng Plateau, Makuleke Wetlands and the Mapungubwe Cultural Landscape. Geography The mountain is intersected by t ...

Transvaal Province
The Province of the Transvaal ( af, Provinsie van Transvaal), commonly referred to as the Transvaal (; ), was a province of South Africa from 1910 until 1994, when a new constitution subdivided it following the end of apartheid. The name "Transvaal" refers to the province's geographical location to the north of the Vaal River. Its capital was Pretoria, which was also the country's executive capital. History In 1910, four British colonies united to form the Union of South Africa. The Transvaal Colony, which had been formed out of the bulk of the old South African Republic after the Second Boer War, became the Transvaal Province in the new union. Half a century later, in 1961, the union ceased to be part of the Commonwealth of Nations and became the Republic of South Africa. The PWV (Pretoria-Witwatersrand-Vereeniging) conurbation in the Transvaal, centred on Pretoria and Johannesburg, became South Africa's economic powerhouse, a position it still holds today as Gauteng Province ...

Witwatersrand
The Witwatersrand () (locally the Rand or, less commonly, the Reef) is a , north-facing scarp in South Africa. It consists of a hard, erosion-resistant quartzite metamorphic rock, over which several north-flowing rivers form waterfalls, which account for the name Witwatersrand, meaning "white water ridge" in Afrikaans.Truswell, J.F. (1977). ''The Geological Evolution of South Africa''. pp. 21, 27–28, 33–36. Cape Town: Purnell. This east-west-running scarp can be traced with only one short gap, from Bedfordview (about west of O.R. Tambo International Airport) in the east, through Johannesburg and Roodepoort, to Krugersdorp in the west (see the diagram at left below).Norman, N.; Whitfield, G. (2006) ''Geological Journeys''. pp. 38–49, 60–61. Cape Town: Struik Publishers. The scarp forms the northern edge of a plateau (or ridge) which rises about above the surrounding plains of the Highveld.

Göran Rothman
Göran (Georg) Rothman (30 November 1739, in Husebybruk, Småland, Sweden – 3 December 1778, in Stockholm), was a Swedish naturalist, physician and an apostle of Carl Linnaeus. His father, Johan Stensson Rothman, was a teacher of Logic and Physics at a grammar school in Växjö, the same school that Carl von Linne attended. Their good relationship dated back to that period. Göran Rothman studied at Uppsala University from 1757 and graduated under Carl von Linne. On 27 May 1763 he defended a dissertation on the disease ''Raphania'' ( ergotism), thought by Linnaeus to be caused by eating bread from freshly harvested grain and wrongly ascribed to the presence of seed of ''Raphanus raphanistrum'' L., the common radish. In 1765 he carried out research in Åland and from 1773 to 1776 in Libya and Tunisia. On his return he practised as physician in Stockholm. He was notable for his translations of Voltaire (1694–1778) and Alexander Pope (1688–1744) into Swedish. The plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
