Kunth
Carl Sigismund Kunth (18 June 1788 – 22 March 1850), also Karl Sigismund Kunth or anglicized as Charles Sigismund Kunth, was a German botanist. He is known for being one of the first to study and categorise plants from the American continents, publishing ''Nova genera et species plantarum quas in peregrinatione ad plagam aequinoctialem orbis novi collegerunt Bonpland et Humboldt'' (7 vols., Paris, 1815–1825). Born in Leipzig, Kunth became a merchant's clerk in Berlin in 1806. After meeting Alexander von Humboldt, who helped him attend lectures at the University of Berlin, Kunth became interested in botany. Kunth worked as Humboldt's assistant in Paris from 1813 to 1819. He classified plants that had been collected by Humboldt and Aimé Bonpland during their journey through the Americas. When Kunth returned to Berlin in 1820, he became Professor of Botany at the University of Berlin, as well as the Vice President of the Berlin botanical garden. In 1829, he was elected membe ...

Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide an alternative food source for ...

Native Species
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho.

South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Provinces
The Cape Provinces of South Africa is a biogeographical area used in the World Geographical Scheme for Recording Plant Distributions (WGSRPD). It is part of the WGSRPD region 27 Southern Africa. The area has the code "CPP". It includes the South African provinces of the Eastern Cape, the Northern Cape and the Western Cape, together making up most of the former Cape Province. The area includes the Cape Floristic Region, the smallest of the six recognised floral kingdoms of the world, an area of extraordinarily high diversity and endemism, home to more than 9,000 vascular plant species, of which 69 percent are endemic.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Angola
The wildlife of Angola is composed of its flora and fauna. An atlas of the amphibians and reptiles of Angola was published in 2018, and reported 117 species of amphibians and 278 of reptiles. A major book on the biodiversity of Angola was published in 2019, and reported more than 2,000 species of organisms (plants, invertebrates and vertebrate animals), and 1,313 fossil species. Fauna Mammals Birds The avifauna of Angola includes a total of 983 species, of which 14 are endemic, 1 has been introduced by humans, and 4 are rare or accidental. 20 species are globally threatened. The western Angola Endemic Bird Area has 14 range-restricted species. Little is known about the conservation status of the region's birds due to the civil war that has raged in Angola for the last 27 years. The greatest diversity of restricted-range species is found in Cuanza Sul province, and given the uncertainty about their current status, many of these species are listed as Threatened. Gabela B ...

Flora Of The Cape Provinces
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
