Retama Rhodorhizoides
''Retama rhodorhizoides'' is a species or subspecies of flowering plant in the family Fabaceae, endemic to the Canary Islands. Taxonomy ''Retama rhodorhizoides'' was first described by Philip Barker-Webb and Sabin Berthelot in a work dated to 1836–1850 that was initially published in parts. An illustration of the species, first published in 1837, was labelled ''Genista rhodorhizoides''. When the authors published a Latin description in 1842, they transferred the species to ''Retama''. The species is included in ''Retama monosperma'' by some sources, and, according to the African Plants Database, has been incorrectly identified as ''Retama raetam'' by others. ''Retama rhodorhizoides'' is restricted to the Canary Islands The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocc .... Referen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabaceae
The Fabaceae or Leguminosae,International Code of Nomenclature for algae, fungi, and plants. Article 18.5 states: "The following names, of long usage, are treated as validly published: ....Leguminosae (nom. alt.: Fabaceae; type: Faba Mill. Vicia L.; ... When the Papilionaceae are regarded as a family distinct from the remainder of the Leguminosae, the name Papilionaceae is conserved against Leguminosae."

Endemism
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] |
Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Barker-Webb
Philip Barker Webb (10 July 1793 – 31 August 1854) was an English botanist. Life Webb was born to a wealthy, aristocratic family; his father was the lord of the manors of Witley and Milford, Surrey, Milford, in Surrey, England. Webb was educated at Harrow School and Christ Church, Oxford. He collected plants in Italy, Spain, and Portugal, and was the first person to collect in the Tetuan Mountains of Morocco. En route to Brazil he made what was intended to be a brief visit to the Canary Islands, but he stayed for a considerable time, returning after his Brazil expedition. The results can be seen in the nine-volume ''Natural History of the Canary Islands, Histoire Naturelle des Iles Canaries'' (''Natural History of the Canary Islands''), which he co-authored with Sabin Berthelot. In company with Berthelot, who had lived on the islands for some time, Webb collected specimens on the islands between 1828 and 1830. The text of ''Histoire Naturelle des Iles Canaries'' took 20&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabin Berthelot
Sabin Berthelot (4 April 1794 – 10 November 1880) was a French naturalist and ethnologist. He was resident on the Canary Islands for part of his life, and co-authored ''L'Histoire Naturelle des Îles Canaries'' (1835–50) with Philip Barker Webb. Berthelot was the son of a Marseille merchant. He joined the French Navy and served as a midshipman during the Napoleonic Wars. After the war he joined the merchant fleet, travelling between Marseilles and the West Indies. He first visited the Canary Islands in 1820, where he taught at a school in Tenerife and managed the botanical gardens at Orotava for the Marquis of Villanueva del Prato. Berthelot studied the natural history of the islands. He was joined in this task by Webb in 1828, and by 1830 they had collected sufficient information for publication. They travelled to Geneva, and produced the first volume of ''L'Histoire Naturelle des Îles Canaries'' in 1835. Berthelot concentrated on the ethnography, history and geography of t ...

Retama
''Retama'' (also known as ''rotem'', he, רותם) is a genus of flowering bushes in the legume family, Fabaceae. It belongs to the broom tribe, Genisteae. ''Retama'' broom bushes are found natively in North Africa, the Levant and some parts of southern Europe. ''Retama raetam'' and ''Retama monosperma'' have white flowers, while ''Retama sphaerocarpa'' has yellow flowers. It remains an open question in taxonomy whether the members of the genus ''Retama'' should be incorporated into the genus ''Genista'' (see Genisteae). The species contain cytisine, a toxic alkaloid. In the Spanish language the name ''retama'' is commonly used for broom bushes in general, including the genus ''Retama''. Taxonomy The genus ''Retama'' was erected in 1838 by Constantine Samuel Rafinesque, the genus name being derived from the Arabic name. Rafinesque noted that the genus had been included in other genera, including ''Spartium'', ''Cytisus'' and ''Genista'', but he regarded it as distinct. The ...

Retama Monosperma
''Retama monosperma'', the bridal broom or bridal veil broom, is a flowering bush species in the genus ''Retama'', native to the western Mediterranean Basin (from Portugal, Morocco and Canary Islands to Italy and Egypt). ''Retama monosperma'' forms root nodules with '' Ensifer fredii''. The larvae of the moths '' Phyllonorycter hesperiella'' and '' Phyllonorycter spartocytisi'' feed on ''R. monosperma''. The seeds contain cytisine, a toxic alkaloid. Fifteen other quinolizidine and three dipiperidine alkaloids can also be isolated from different parts of the plant. In particular, the presence of (+)-sparteine Sparteine is a class 1a antiarrhythmic agent; a sodium channel blocker. It is an alkaloid and can be extracted from scotch broom. It is the predominant alkaloid in '' Lupinus mutabilis'', and is thought to chelate the bivalent cations calcium and ..., α- and β- isosparteine, (+)-17- oxosparteine, (-)- lupanine, 5,6-dehydrolupanine, (-)- anagyrine, (-)- N-methylcytis ...

Retama Raetam
''Retama raetam'' is a species of flowering plant in the family Fabaceae, native to northern Africa from the Western Sahara to Sudan, Sicily, Israel, Sinai Peninsula, the Palestine region and Saudi Arabia, and widely naturalized elsewhere. File:Osmia gracilicornis male 1.jpg, Flowers with pollinating bee, '' Osmia gracilicornis'' Taxonomy The species was first described in 1775 by Peter Forsskål as ''Genista raetam''. The epithet was derived from the Hebrew name from the Hebrew Bible. Retama raetam is mentioned in the Hebrew Bible, in Books of Kings and in Book of Job. the Hebrew name is "Rotem", and the translated name is "Broom tree". . The species was transferred to ''Retama'' by Philip Barker-Webb and Sabin Berthelot in part of a publication that has been dated to 1842. The species that occurs in the Canary Islands is now considered to be ''Retama rhodorhizoides ''Retama rhodorhizoides'' is a species or subspecies of flowering plant in the family Fabaceae, endemic to ...

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 stan ...
