Euclea Crispa
''Euclea crispa'',''crispa'' = "curled", referring to the leaf margins that may be rolled under or wavy commonly known as the blue guarri,The Khwe appelation "Gwarri" is also the origin of the Afrikaans and Xhosa loan words, "Ghwarrie" and "umGwali", respectively. is an Afrotropical plant species of the family Ebenaceae. The hardy and evergreen plants may form a dense stand of shrubs, or grow to tree size. It is widespread and common in the interior regions of southern Africa, and occurs northward to the tropics. Though some are present near the South African south and east coasts, they generally occur at middle to high altitudes. It is readily recognizable from its much-branched structure and dull bluish foliage colour. Those bearing lanceolate leaves may however resemble the Wild olive, another common species of the interior plateaus. Range and habitat It is native to central South Africa (where one of 35 native ebony species), Lesotho, Eswatini, the Zimbabwean plateau and Eas ...

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 ...

Epidermis (botany)
The epidermis (from the Greek ''ἐπιδερμίς'', meaning "over-skin") is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment. The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. The epidermis of most leaves shows dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions. Woody stems and some other stem structures such as potato tubers produce a secondary covering called the periderm that replaces the epidermis as the protective covering. Description The epidermis is the outermost cell layer of the primary plant body. In some older works the cells of the leaf epidermis have been regarded as specialized parenchyma cells,Hill, J. Ben; Overholts, Lee O; Popp, H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laxative
Laxatives, purgatives, or aperients are substances that loosen stools and increase bowel movements. They are used to treat and prevent constipation. Laxatives vary as to how they work and the side effects they may have. Certain stimulant, lubricant and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea. Some laxatives combine more than one active ingredient. Laxatives may be administered orally or rectally. Types Bulk-forming agents Bulk-forming laxatives, also known as roughage, are substances, such as fiber in food and hydrophilic agents in over-the-counter drugs, that add bulk and water to stools so that they can pass more easily through the intestines (lower part of the digestive tract). Properties * Site of action: small and large intestines * Onset of action: 12–72 hours * Examples: dietary fiber, Metamucil, Citru ...

Black Rhinoceros
The black rhinoceros, black rhino or hook-lipped rhinoceros (''Diceros bicornis'') is a species of rhinoceros, native to eastern and southern Africa including Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as ''black'', its colours vary from brown to grey. The other African rhinoceros is the white rhinoceros (''Ceratotherium simum''). The word "white" in the name "white rhinoceros" is often said to be a misinterpretation of the Afrikaans word ' (Dutch ') meaning wide, referring to its square upper lip, as opposed to the pointed or hooked lip of the black rhinoceros. These species are now sometimes referred to as the square-lipped (for white) or hook-lipped (for black) rhinoceros. The species overall is classified as critically endangered (even though the south-western black rhinoceros is classified as near threatened). Three subspecies have been declared extinct, including the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kuruman
Kuruman is a small town with just over 53,000 inhabitants in the Northern Cape province of South Africa. It is known for its scenic beauty and the Eye of Kuruman, a geological feature that brings water from deep underground. The abundance of water produces an unexpected swathe of green amidst the barren plains and is known as the Oasis of the Kalahari. It was at first a mission station of the London Missionary Society founded by Robert Moffat in 1821. It was also the place where David Livingstone arrived for his first position as a missionary in 1841. The Kuruman River, which is dry except for flash floods after heavy rain, is named after the town. Origins Kuruman is regarded as the “Oasis of the Kalahari”. It is set out on the Ghaap Plateau and receives its water source from a spring called “The Eye” which rises in a cave in the semidesert thornveld area in the Kalahari region. Kuruman is the main town in the area and the spring gives about 20 to 30 million litres of wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimberley, Northern Cape
Kimberley is the capital and largest city of the Northern Cape province of South Africa. It is located approximately 110 km east of the confluence of the Vaal and Orange Rivers. The city has considerable historical significance due to its diamond mining past and the siege during the Second Anglo-Boer war. British businessmen Cecil Rhodes and Barney Barnato made their fortunes in Kimberley, and Rhodes established the De Beers diamond company in the early days of the mining town. On 2 September 1882, Kimberley was the first city in the Southern Hemisphere and the second in the world after Philadelphia, Pennsylvania in the United States to integrate electric street lights into its infrastructure. The first stock exchange in Africa was built in Kimberley, as early as 1881. History Discovery of diamonds In 1866, Erasmus Jacobs found a small brilliant pebble on the banks of the Orange River, on the farm ''De Kalk'' leased from local Griquas, near Hopetown, which was h ...

About 2000 years BP the semi-nomadic Khoikhoi (or Khoekhoen or Khoikhoin) arrived with cattle, sheep and goats. These pastoralists migrated south towards the coast. Rock paintings and petroglyphs (engravings) remain as evidence of the first people who lived here. By the 4th century AD Bantu-speaking people had begun to migrate from central Africa down the east coast into southern Africa.
