Craterostigma Plantagineum
''Craterostigma plantagineum'', is a resurrection plant species in the genus '' Craterostigma''. It is a dwarf growing plant and can be found (in ideal conditions) to make a 'carpet' across the ground, with blooms in shades of blue and purple. It is a well-studied desiccation-tolerant species known for its extreme vegetative tolerance against dehydration and desiccation. It is native to parts of Africa and to India. It is known as a resurrection plant (meaning it can dry out and stay dormant for long periods and then come back to life after some rain). Description ''Craterostigma plantagineum'' has an orange-red to yellow rhizome with hairy roots underneath.Joachim W. Kadereit (Editor) It has a rosette of leaves,Gwithie Kirby which are variable, ranging from narrow elliptic, lanceolate, to broadly ovate. The leaf is approx. 50mm in diameter.Horst Wild They can be lightly hairy on both surfaces, or hairless above and hairy beneath. They conspicuously veined, or ribbed. The v ...

Christian Ferdinand Friedrich Hochstetter
Christian Ferdinand Friedrich Hochstetter (16 February 1787 – 20 February 1860) was a German botanist and Protestant minister. Biography Hochstetter was born in Stuttgart in Baden-Württemberg. He was the father of geologist Ferdinand Hochstetter (1829–1884). In 1807 Hochstetter received his degree of Master of Divinity in Tübingen. While still a student, he became a member of a secret organization headed by Carl Ludwig Reichenbach (1788–1869) that had designs on establishing a colony on Tahiti (''Otaheiti-Gesellschaft''). In 1808 the organization was discovered by authorities, and its members suspected of treason and arrested. Hochstetter was imprisoned for a short period of time for his small role in the secret society. Later on, he spent six months as a teacher in a private institution in Erlangen, and afterwards was a tutor for four years in the house of the Minister of Altenstein in Thuringia. In 1816 he became a pastor and school inspector in Brno, moving to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spermine
Spermine is a polyamine involved in cellular metabolism that is found in all Eukaryote, eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some Bacterium, bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses. Antonie van Leeuwenhoek first described crystals of spermine phosphate in human semen in 1678. The name ''spermin'' was first used by the German chemists Albert Ladenburg, Ladenburg and Abel in 1888, and the correct structure of spermine was not finally established until 1926, simultaneously in England (by Dudley, Rosenheim, and Starling) and Germany (by Wrede et al.). Spermine is the chemical primarily responsible for the characteristic odor of semen. Derivative A derivative (chemistry), derivative of spermine, N1, N12-bis(ethyl)spermine (also known as BESm) was investig ...

Chad
Chad (; ar, تشاد , ; french: Tchad, ), officially the Republic of Chad, '; ) is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the southwest, Nigeria to the southwest (at Lake Chad), and Niger to the west. Chad has a population of 16 million, of which 1.6 million live in the capital and largest city of N'Djamena. Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the second-largest wetland in Africa. Chad's official languages are Arabic and French. It is home to over 200 different ethnic and linguistic groups. Islam (55.1%) and Christianity (41.1%) are the main religions practiced in Chad. Beginning in the 7th millennium BC, human populations moved into the Chadian basin in great numbe ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Plant
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 ...

True Plantains
"True" plantains are a group of cultivars of the genus ''Musa'' ( bananas and plantains) placed in the African Plantain subgroup of the AAB chromsome group. Although "AAB" and "true plantain" are often used interchangeably, plantains are just the most popular varieties among the AABs. The term "plantain" can refer to all the banana cultivars which are normally eaten after cooking, rather than raw (see cooking banana), or it can refer to members of other subgroups of ''Musa'' cultivars, such as the Pacific plantains, although in Africa there is little to no distinction made between the two, as both are commonly cooked. True plantains are divided into four groups based on their bunch type: French, French Horn, False Horn, and Horn plantains. Each bunch type has a variety of cultivars associated with it: * French cultivars: 'Obino l'Ewai' (Nigeria), 'Nendran' (India), 'Dominico' (Colombia) * French Horn cultivars: 'Batard' (Cameroon), 'Mbang Okon' (Nigeria) * False Horn cultivars: ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Ndebele Language
Northern Ndebele (), also called Ndebele, isiNdebele saseNyakatho, Zimbabwean Ndebele or North Ndebele, associated with the term Matabele, is a Bantu language spoken by the Northern Ndebele people which belongs to the Nguni group of languages. As a start and to give some context, Ndebele is a term used to refer to a collection of many different African cultures in Zimbabwe. It perhaps by default became a 'language' (for lack of better word) spoken predominantly by the descendants of Mzilikazi. As a language, it is by no means similar to the Ndebele language spoken in kwaNdebele in South Africa although, like many Nguni dialects, some words will be shared. Many of the natives that were colonized by the Matabele were assimilated into Mzilikazi's kingdom to create a version of isiZulu. The Matebele people of Zimbabwe descend from followers of the Zulu leader Mzilikazi (one of Zulu King Shaka's generals), who left the Zulu Kingdom in the early 19th century, during the Mfecane, arr ...

Tonga Language (Zambia And Zimbabwe)
Tonga (''Chitonga''), also known as ''Zambezi'', is a Bantu language primarily spoken by the Tonga people (''Batonga'') who live mainly in the Southern province, Lusaka province Central Province and Western province of Zambia, and in northern Zimbabwe, with a few in Mozambique. The language is also spoken by the Iwe, Toka and Leya people, and perhaps by the Kafwe Twa (if they are not Ila), as well as many bilingual Zambians and Zimbabweans. In Zambia tonga is taught in schools as first language in the whole of Southern Province, Lusaka and Central Provinces. It is one of the major lingua francas in Zambia, together with Bemba, Lozi and Nyanja. The Tonga of Malawi, which is classified by Guthrie as belonging to zone N15, is not particularly close to Zambian Tonga, which is classified as zone M64, and can be considered a separate language. The Tonga-speaking inhabitants are the oldest Bantu settlers, with the Tumbuka, a small ethnic group in the east, in what is now known ...
