Zygophyllum Stapffii
''Zygophyllum stapffii'', synonym ''Tetraena stapffii'', (Afrikaans: ''daalderplant'', English: ''dollar bush'') is a species of flowering bush endemic to Namibia. , the specific epithet was sometimes spelt with a single ''f'', i.e. ''stapfii'', but the International Plant Names Index spells it with double ''f''. It grows in the Namib ecoregion along the Atlantic Ocean coast. Most of this plant's moisture comes from the morning mist. The shrub's round, coin-like leaves lend it its colloquial name: ''daalder'' is an old Dutch coin worth one and a half guilder Guilder is the English translation of the Dutch and German ''gulden'', originally shortened from Middle High German ''guldin pfenninc'' " gold penny". This was the term that became current in the southern and western parts of the Holy Roman E ...s.

Hans Schinz
Hans Schinz (6 December 1858 – 30 October 1941) was a Swiss explorer and botanist who was a native of Zürich. In 1884 he participated in an exploratory expedition to German Southwest Africa that was organized by German merchant Adolf Lüderitz (1834–1886). For the next few years Schinz undertook extensive scientific studies of the northern parts of the colony. As a result of the expedition, he published ''Deutsch-Südwestafrika, Forschungsreisen durch die deutschen Schutzgebiete Groß- Nama- und Hereroland, nach dem Kunene, dem Ngamisee und Kalahari884-1887'' (German South West Africa: Research Expedition of Herero and Nama Country, the Kunene Region, Lake Ngami and the Kalahari; 1884–1887). This work was an important scientific, geographic and ethnographic study of the colony, and was one of the first comprehensive works on the Ovamboland region. It was during this expedition that he made the acquaintance of the Finnish missionary Martti Rautanen (1845–1926) at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San, Damara and Nama people. Around the 14th century, immigrating Bantu peoples arrived as part of the Bantu expansion. Since then, the Bantu groups, the largest being the ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew ( Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth#Surface, Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8th paralle ...

Mist
Mist is a phenomenon caused by small droplets of water suspended in the cold air, usually by condensation. Physically, it is an example of a dispersion. It is most commonly seen where water vapor in warm, moist air meets sudden cooling, such as in exhaled air in the winter, or when throwing water onto the hot stove of a sauna. It can be created artificially with aerosol canisters if the humidity and temperature conditions are right. It can also occur as part of natural weather, when humid air cools rapidly, notably when the air comes into contact with surfaces that are much cooler than the air (e.g. mountains). The formation of mist, as of other suspensions, is greatly aided by the presence of nucleation sites on which the suspended water phase can congeal. Thus even such unusual sources of nucleation as small particulates from volcanic eruptions, releases of strongly polar gases, and even the magnetospheric ions associated with polar lights can in right conditions tr ...

Guilder
Guilder is the English translation of the Dutch and German ''gulden'', originally shortened from Middle High German ''guldin pfenninc'' " gold penny". This was the term that became current in the southern and western parts of the Holy Roman Empire for the Fiorino d'oro (introduced in 1252). Hence, the name has often been interchangeable with ''florin'' (currency sign ''ƒ'' or ''fl.''). The guilder is also the name of several currencies used in Europe and the former colonies of the Dutch Empire. Gold guilder The guilder or gulden was the name of several gold coins used during the Holy Roman Empire. It first referred to the Italian gold florin introduced in the 13th century. It then referred to the Rhenish gulden (florenus Rheni) issued by several states of the Holy Roman Empire from the 14th century. The Rhenish gulden was issued by Trier, Cologne and Mainz in the 14th and 15th centuries. Basel minted its own ''Apfelgulden'' between 1429 and 1509. Bern and Solothurn fol ...

Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia and Australia. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', '' Fagonia'', '' Roepera'' and ''Tetraena''. Species In accordance with International Plant Names Index, genus ''Zygophyllum'' currently has 117 accepted species: *''Zygophyllum acerosum'' (Boiss.) Christenh. & Byng *''Zygophyllum aegyptium'' Hosny *''Zygophyllum album'' L.f. *''Zygophyllum applanatum'' Van Zyl *''Zygophyllum arabicum'' (L.) Christenh. & Byng *''Zygophyllum atriplicoides'' ...
