Rhododendron Subgenus Rhododendron
''Rhododendron hirsutum'' ''Rhododendron'' subgenus ''Rhododendron'' is a subgenus of the genus ''Rhododendron''. With around 400 species, it is the largest of the eight subgenera (more recently reduced to five) containing nearly half of all known species of ''Rhododendron'' and all of the lepidote (scales on the underside of the leaves) species. Taxonomy The subgenus has traditionally included three sections: *''Rhododendron'' sect. '' Pogonanthum'' Aitch. & Hemsl, type ''Rhododendron anthopogon'' D.Don. Six species; Himalaya and adjacent mountains *''Rhododendron'' sect. ''Rhododendron'' L., type : ''Rhododendron ferrugineum'' L. 120 - 149 species in 25 subsections; temperate to subarctic Northern Hemisphere *''Rhododendron'' sect. ''Vireya'' (Blume) Copel.f., type ''Rhododendron javanicum'' (Blume) Benn. About 300 species in 7 subsections; tropical southeast Asia, Australasia. Has at times been considered as a separate ninth subgenus. However, following phylogenetic anal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhododendron Ferrugineum
''Rhododendron ferrugineum'', the alpenrose, snow-rose, or rusty-leaved alpenrose is an evergreen shrub that grows just above the tree line in the Alps, Pyrenees, Jura and northern Apennines, on acid soils. It is the type species for the genus ''Rhododendron''. Description ''Rhododendron ferrugineum'' may grow up to tall and produces clusters of pinkish-red, bell-shaped flowers throughout the summer. The undersides of the leaves are covered in rust-brown spots, which give the species the second part of its binomial name ('' ferrugineum'', Latin for 'rust-coloured, ferruginous'). This is in contrast to ''Rhododendron hirsutum'', which has no such brown colouring, has hairy edges to the leaves and grows over limestone. Where the two species co-occur (usually on soils of intermediate pH), the hybrid ''Rhododendron × intermedium'' may occur; as its name suggests, it is intermediate in form between the two parental species. Habitat ''Rhododendron ferrugineum'' grows primarily on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Systematic Botany
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Rhododendron Subsect
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. Species Description ''Rhododendron'' is a genus of shrubs and small to (rarely) large trees, the smallest species growing to tall, ...

Identification Key
In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains. Identification keys are also used in many other scientific and technical fields to identify various kinds of entities, such as diseases, soil types, minerals, or archaeological and anthropological artifacts. Traditionally identification keys have most commonly taken the form of single-access keys. These work by offering a fixed sequence of ''identification steps'', each with multiple alternatives, the choice of which determines the next step. If each step has only two alternatives, the key is said to be dichotomous, else it is polytomous. Modern multi-access or ''interactive keys'' allow the user to freely choose the identification steps and their order. At each step, the user must answer a question about one or more features (''characters'') of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malesian
Malesia is a biogeographical region straddling the Equator and the boundaries of the Indomalayan and Australasian realms, and also a phytogeographical floristic region in the Paleotropical Kingdom. It has been given different definitions. The World Geographical Scheme for Recording Plant Distributions split off Papuasia in its 2001 version. Floristic province Malesia was first identified as a floristic region that included the Malay Peninsula, the Malay Archipelago, New Guinea, and the Bismarck Archipelago, based on a shared tropical flora derived mostly from Asia but also with numerous elements of the Antarctic flora, including many species in the southern conifer families Podocarpaceae and Araucariaceae. The floristic region overlaps four distinct mammalian faunal regions. The first edition of the World Geographical Scheme for Recording Plant Distributions (WGSRPD) used this definition, but in the second edition of 2001, New Guinea and the Bismarck Archipelago were remove ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section ( la, sectio) is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making new combinations, i.e. many new binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect. ''Bursatae'' See also * Section (biology) References Section Section, Sectioning or Sectioned may refer to: Arts, entertainment and media * Section (music), a complete, but not independent, musical idea * Section (typography), a subdivision, especially ...
