Leucospermum Truncatulum
''Leucospermum truncatulum'' is a slender, upright, evergreen, hardly branching shrub of up to 2 m (6 ft) high, with felty inverted egg-shaped to oval, leaves with entire margins of 1–2½ cm (0.4–1.0 in) long and ½–1 cm (0.2–0.4 in) wide. It has small globe-shaped, at first yellow, later pinkish flower heads of 1½–2 cm (0.6-0.8 in) in diameter, without a stalk, usually crowded with two to eight together near the end of the stems. It is known as oval-leaf pincushion in English, and patrysbos or kleinkopspeldekussing in Afrikaans. It is an endemic species of the south of the Western Cape province of South Africa, and flowers between August and December. Description The oval-leaf pincushion is a slender, stiffly upright and very sparsely branching evergreen shrublet mostly 1–1½ m, occasionally up to 2 m (6 ft) high, with a single basal stem. The flowering stems are slender, 3–4 mm (0.12–0.16 in) in diameter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Patrick Rourke
John Patrick Rourke FMLS (born 26 March 1942, in Cape Town) is a South African botanist, who worked at the Kirstenbosch National Botanical Garden and became curator of the Compton Herbarium. He is a specialist in the flora of the Cape Floristic Region, in particular the family Proteaceae. Career Rourke studied at the University of Cape Town from 1960 to 1970, where he obtained his B.Sc., M.Sc. and Ph.D. He started working at Kirstenbosch from 1966, and succeeded Winsome Fanny Barker as curator of the Compton Herbarium in 1972. He published several revisions of Proteacean genera including ''Leucadendron'', ''Leucospermum'', ''Mimetes'', ''Vexatorella'', '' Sorocephalus'' and '' Spatalla''. During his career he collected approximately 2000 specimens of flora from the southwestern and southern Cape, Namaqualand and eastern Transvaal. In 1997 he was made foreign member of the Linnean Society of London. In 2003 Rourke was awarded the "Gold medal for Lifetime Preservation of the ...

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combinations based on a suppressed name are also listed as “''nom. re ...

Buxus
''Buxus'' is a genus of about seventy species in the family Buxaceae. Common names include box or boxwood. The boxes are native to western and southern Europe, southwest, southern and eastern Asia, Africa, Madagascar, northernmost South America, Central America, Mexico and the Caribbean, with the majority of species being tropical or subtropical; only the European and some Asian species are frost-tolerant. Centres of diversity occur in Cuba (about 30 species), China (17 species) and Madagascar (9 species). They are slow-growing evergreen shrubs and small trees, growing to 2–12 m (rarely 15 m) tall. The leaves are opposite, rounded to lanceolate, and leathery; they are small in most species, typically 1.5–5 cm long and 0.3–2.5 cm broad, but up to 11 cm long and 5 cm broad in ''B. macrocarpa''. The flowers are small and yellow-green, monoecious with both sexes present on a plant. The fruit is a small capsule 0.5–1.5 cm long (to 3 cm i ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Leucospermum
''Leucospermum'' is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species. Almost all species are easily recognised as ''Leucospermum'' because of the long protruding styles with a thickened pollen-presenter, which jointly give the flower head the appearance of a pincushion, its common name. Pincushions can be found in South Africa, Swaziland, Zimbabwe and Mozambique. The shrubs mostly have a single stem at their base, but some species sprout from an underground rootstock, from which the plant can regrow after fire has killed the above ground biomass. In a larger group of species, specimens are killed by fire, and their survival depends on the seeds. In all species, seeds are collected by ants, which take them to their underground nests to feed on their ant breads, a seed dispersal strategy known as myrmecochory. This ensures that the seeds do not burn, so new plants can grow from them. ''Leucospermum ... [...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 ...

Combinatio Nova
''Combinatio nova'', abbreviated ''comb. nov.'' (sometimes ''n. comb.''), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not to be confused with ', used for a previously unnamed species. There are three situations: * the taxon is moved to a different genus * an infraspecific taxon is moved to a different species * the rank of the taxon is changed. Examples When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when ''Calymmatobacterium granulomatis'' was renamed ''Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination. See also * Glossary of scientific naming * Basionym * List of Latin phrases * Nomenclature code Nomenclature codes or codes of nomenclature are the various rulebooks that govern biological taxonomic nomenclature, each in the ...

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 Oluk ...

Form (botany)
In botanical nomenclature, a ''form'' (''forma'', plural ''formae'') is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the full "forma" should be put before the infraspecific epithet to indicate the rank. It is not italicised. For example: * '' Acanthocalycium spiniflorum'' f. ''klimpelianum'' or ** ''Acanthocalycium spiniflorum'' forma ''klimpelianum'' (Weidlich & Werderm.) Donald * ''Crataegus aestivalis'' (Walter) Torr. & A.Gray var. ''cerasoides'' Sarg. f. ''luculenta'' Sarg. is a classification of a plant whose name is: ** ''Crataegus aestivalis'' (Walter) Torr. & A.Gray f. ''luculenta'' Sarg. A form usually designates a group with a noticeable mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michel Gandoger
Abbé Jean Michel Gandoger (10 May 1850 – 4 October 1926), was a French botanist and mycologist. He was born in Arnas, Rhône, Arnas, the son of a wealthy vineyard owner in the Beaujolais region. Although he took holy orders at the age of 26, he devoted his life to the study of botany, specializing in the genus ''Rose, Rosa''. He travelled throughout the Mediterranean, notably Crete, Spain, Portugal, and Algeria, amassing a herbarium of over 800,000 specimens, now kept at the Jardin botanique de Lyon. However, he is notorious for having published thousands of plant species that are no longer accepted. He died at Arnas in 1926. Father J B Charbonnel published an obituary in the Bulletin de la Societe botanique de France (1927, Vol. 74, 3–11), listing Gandoger's many publications. Plants with the specific epithet of ''gandogeri'' are named after him, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurt Polycarp Joachim Sprengel
Kurt Polycarp Joachim Sprengel (3 August 1766 – 15 March 1833) was a German botanist and physician who published an influential multivolume history of medicine, ''Versuch einer pragmatischen Geschichte der Arzneikunde'' (1792–99 in four volumes with later editions running to five) and several other medical reference works. Biography Sprengel was born at Boldekow in Pomerania, and he is considered of German nationality. His father, a clergyman, provided him with a thorough education of wide scope; as boy he distinguished himself as a linguist, in Latin and Greek, and also Arabic; his uncle, Christian Konrad Sprengel (1750–1816), is remembered for his studies in the fertilization of flowers by insects – a subject in which he reached conclusions many years ahead of his time. Spreng. appeared as an author at the age of fourteen, publishing a small work called '' Anleitung zur Botanik für Frauenzimmer'' ("guide to botany for women") in 1780. In 1784 he began to study the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomen Nudum
In taxonomy, a ''nomen nudum'' ('naked name'; plural ''nomina nuda'') is a designation which looks exactly like a scientific name of an organism, and may have originally been intended to be one, but it has not been published with an adequate description. This makes it a "bare" or "naked" name, which cannot be accepted as it stands. A largely equivalent but much less frequently used term is ''nomen tantum'' ("name only"). In zoology According to the rules of zoological nomenclature a ''nomen nudum'' is unavailable; the glossary of the ''International Code of Zoological Nomenclature'' gives this definition: And among the rules of that same Zoological Code: In botany According to the rules of botanical nomenclature a ''nomen nudum'' is not validly published. The glossary of the ''International Code of Nomenclature for algae, fungi, and plants'' gives this definition: The requirements for the diagnosis or description are covered by articles 32, 36, 41, 42, and 44.
