Prometheum
''Prometheum'' is a genus of plants in the family Crassulaceae. Taxonomy The species in the genus ''Prometheum'' include: * ''Prometheum pilosum'' (M.Bieb.) H.Ohba * ''Prometheum sempervivoides'' (Fisch. ex M.Bieb.) H.Ohba * ''Prometheum tymphaeum'' (Quézel & Contandr.) 't Hart ''P. sempervivoides'' and ''P. pilosum'' were historically included in genera ''Sedum'' (section ''Cyprosedum''), and later ''Rosularia'', but were elevated to a separate genus by Ohba (1995). Description According to an experiment done on interspecific plant crosses in the family Crassulaceae, the genus ''Prometheum'' produced on average 55 seeds. Furthermore, the same experiment found that plants of the genus ''Prometheum'' formed a comparium with each other, meaning they were capable of interbreeding. Distribution and habitat From Anatolia to Iran, through the Caucasus The Caucasus () or Caucasia (), is a region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, ...

Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedum
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera '' Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are ''Sedum acre'', ''Sedum album'', '' Sedum dasyphyllum'', '' Sedum reflexum'' (also known as ''Sedum rupestre'') and ''Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosularia
''Rosularia'' is a small genus of the family Crassulaceae. It includes about 28-35 species from Europe, the Himalayas, and northern Africa. Taxonomy ''Rosularia'' was originally described by De Candolle (1828) as a section of the genus Umbilicus, and raised to the level of genus by Stapf (1923) Thus the genus bears the botanical authority ( DC) Stapf of both authors. In 1930 Berger included it in family Crassulaceae subfamily Sedoideae, as one of 9 genera. He further divided it into two sections (Eu-Rosularia and Ornithogalopsis) and further series, transferring some species of ''Sedum'' to it. Since then a number of species have been transferred in and out of the genus, including ''S. sempervivoides'', which at one stage was placed in ''Prometheum''. The genus ''Sempervivella'' was submerged in ''Rosularia''. The genus is now placed within the Leucosedum clade, tribe Sedeae, subfamily Sempervivoideae of the Crassulaceae, but is embedded within ''Sedum'' paraphyletically. S ...

Chemical Element
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol ''Z'') – all atoms with the same atomic number are atoms of the same element. Almost all of the baryonic matter of the universe is composed of chemical elements (among rare exceptions are neutron stars). When different elements undergo chemical reactions, atoms are rearranged into new compounds held together by chemical bonds. Only a minority of elements, such as silver and gold, are found uncombined as relatively pure native element minerals. Nearly all other naturally occurring elements occur in the Earth as compounds or mixtures. Air is primarily a mixture o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alwin Berger
Alwin Berger (28 August 1871 – 20 April 1931) was a German botanist best known for his contribution to the nomenclature of succulent plants, particularly agaves and cacti. Born in Germany he worked at the botanical gardens in Dresden and Frankfurt. From 1897 to 1914 he was curator of the Giardini Botanici Hanbury, the botanical gardens of Sir Thomas Hanbury at La Mortola, near Ventimiglia in northwestern Italy, close to the border with France. After working in Germany from 1914 to 1919, Berger studied in the United States for three years, before spending his final years as director of the department of botany of the natural history museum in Stuttgart His main work, ''Die Agaven'', published in 1915, described 274 species of agave, divided into 3 subgenera, '' Littaea'', '' Euagave'' and ''Manfreda''. He also recognised a new genus of cactus, ''Roseocactus'', in 1925. The genera ''Bergerocactus'' (''Cactaceae'') and ''Bergeranthus'' (''Mesembryanthemaceae'') are named in ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Anatolia
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asian ...
