Crataegus Oxycantha
The name ''Crataegus oxyacantha'' L. has been rejected as being of uncertain application, but is sometimes still used. Taxonomy Linnaeus introduced the name ''Crataegus oxyacantha'' for a species of Northern European hawthorn and the name gradually became used for several similar species, which were assumed to be the same, particularly the Midland hawthorn '' C. laevigata'' and the common hawthorn '' C. monogyna''. In 1946, Dandy showed that Linnaeus had actually observed and described a single-styled species similar to the common hawthorn, and the Midland hawthorn was effectively a later discovery. However, Byatt showed that confusion over the true identity of ''C. oxyacantha'' remained, and the name was formally rejected as ambiguous by the International Botanical Congress.. More recently, Christensen Christensen may refer to: * Christensen (surname) * Christensen (constructor), a former racing car constructor * 164P/Christensen, a periodic comet * 170P/Christensen, a perio ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crataegus Laevigata
''Crataegus laevigata'', known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain (where it is typically found in ancient woodland and old hedgerows) and Spain, east to Romania and Ukraine. The species name is sometimes spelt ''C. levigata'', but the original orthography is ''C. lævigata''. Description It is a large shrub or small tree growing to or rarely to tall, with a dense crown. The leaves are long and broad, with two or three shallow, forward-pointing lobes on each side of the leaf. The hermaphrodite flowers are produced in corymbs of 6 to 12, each flower with five white or pale pink petals and two or sometimes three styles. They are pollinated by insects. The fruit is a dark red pome diameter, slightly broader than long, containing two or three nutlets. It flowers in May to June (UK) in rather lax clusters. The flowers are usually white, but can be pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, whitethorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family, Rosaceae. It grows to about tall, producing plant sexuality, hermaphrodite flowers in late spring. The berry-like pomes (known as haws) contain a stone-encased seed. The plant is native to Europe, but has been introduced in many other parts of the world. The pome flesh is of little culinary interest due to its dryness, but is used to make jellies. The young leaves and petals are also edible. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The Bark (botany), bark is dull brown with vertical orange cracks. The younger stems bear sharp thorns, about long. The leaves are long, obovate, and deeply lobed, sometimes almost to the midrib, with the lobes spreading at a wide angle. The upper surface is dark green above and paler underneath. The hermaphrodite flowers are produced i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Edgar Dandy
James Edgar Dandy (24 September 1903, in Preston, Lancashire – 10 November 1976, in Tring) was a British botanist, Keeper of Botany at the British Museum (Natural History) between 1956 and 1966. He was a world specialist on the plant genus ''Potamogeton'' and the family Magnoliaceae. Life Dandy was educated at Preston Grammar School and after that at Downing College, Cambridge, where he took his B.A. In 1925, he was appointed as an assistant to John Hutchinson at Kew Gardens, who worked on a new Angiosperm classification. He gave Dandy the opportunity to revise three taxa, one of which was Magnoliaceae. He became Fellow of the Linnean Society in 1927. On 11 July the same year, he was appointed Second class Assistant at the British Museum Department of Botany. He stayed here until his retirement in 1966. In 1936 he was promoted to First class Assistant, in 1946 to Principal Scientific Officer, and in 1956 he eventually became Keeper of Botany. After his retirement, he kept act ...

International Botanical Congress
International Botanical Congress (IBC) is an international meeting of Botany, botanists in all scientific fields, authorized by the International Association of Botanical and Mycological Societies (IABMS) and held every six years, with the location rotating between different continents. The current numbering system for the congresses starts from the year 1900; the XX IBC was in Madrid, Spain, July 2024. The XXI IBC is planned to be in Cape Town, South Africa, in July 2029. The IBC has the power to alter the ICN (International Code of Nomenclature for algae, fungi, and plants), which was renamed from the International Code of Botanical Nomenclature (ICBN) at the XVIII IBC. Formally the power resides with the Plenary Session; in practice this approves the decisions of the Nomenclature Section. The Nomenclature Section meets before the actual Congress and deals with all proposals to modify the Code: this includes ratifying recommendations from sub-committees on conserved name, conserv ...

Knud Ib Christensen
Knut ( Norwegian and Swedish), Knud ( Danish), or Knútur ( Icelandic) is a Scandinavian and German first name, of which the anglicised form is Canute. In Germany both "Knut" and "Knud" are used. In Spanish and Portuguese Canuto is used which comes from the Latin version Canutus, and in Finland, the name Nuutti is based on the name Knut. The name is derived from the Old Norse Knútr meaning "knot". In English the ''K'' is not mute, so the name is not properly pronounced ''nut'' or ''nute''. It is the name of several medieval kings of Denmark, two of whom also reigned over England during the first half of the 11th century.

American Society Of Plant Taxonomists
The American Society of Plant Taxonomists (ASPT) is a botany, botanical organization formed in 1935 to "foster, encourage, and promote education and research in the field of plant taxonomy, to include those areas and fields of study that contribute to and bear upon taxonomy and herbaria", according to its bylaws. It is incorporated in the state of Wyoming, and its office is at the University of Wyoming, Department of Botany. The ASPT publishes a quarterly botanical journal, ''Systematic Botany'', and the irregular series ''Systematic Botany Monographs''. The society gives annual awards for excellence in Botany. The Society gives the Asa Gray Award for "outstanding accomplishments pertinent to the goals of the Society," and the Peter Raven Award to a botanist who has "made exceptional efforts at outreach to non-scientists." __TOC__ Asa Gray Awardees *2021: Elizabeth Kellogg *2020: Jeff Doyle *2019: Lucinda McDade *2018: Vicki Funk *2017: Michael Donoghue *2016: Peter F.
