Crataegus Oxyacantha
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 concluded that the species studied by Linnaeus matches '' C. rhipidophylla'' Gand. Abbé Jean Michel Gandoger (10 May 1850 – 4 October 1926), was a French botanist and mycologis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Laurentius Salvius
Laurentius is a Latin given name and surname that means "''From Laurentum''" (a city near Rome). It is possible that the place name ''Laurentum'' is derived from the Latin ''laurus'' ("laurel").

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 the Czech Republic and Hungary. It is also present in North Africa. 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. The flowers are pollinated by insects. The fruit is a dark red pome diameter, slightly broader than long, containing two or three nutlets. It is distinguished from the closely related common ...

Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world. Names This species is one of several that have been referred to as ''Crataegus oxyacantha'', a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name ''C. apiifolia'' for a European hawthorn now included in ''C. monogyna,'' but that name is illegitimate under the rules of botanical nomenclature. Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May in the English-speaking parts of Europe) quickthorn, whitethorn, motherdie, and haw. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear shar ...

He was a world specialist on the plant genus ''Potamogeton'' and the family Magnoliaceae. Life Dandy was educated at Winckley Square#Preston Grammar School, 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 (botanist), 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.

International Botanical Congress
International Botanical Congress (IBC) is an international meeting of 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 XVIII IBC was held in Melbourne, Australia, 24–30 July 2011, and the XIX IBC was held in Shenzhen, China, 23–29 July 2017. 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 conservation. ...

American Society Of Plant Taxonomists
The American Society of Plant Taxonomists (ASPT) is a 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.

Crataegus Rhipidophylla
''Crataegus rhipidophylla'' is a species of hawthorn which occurs naturally from southern Scandinavia and the Baltic region to France, the Balkan Peninsula, Turkey, Caucasia, and Ukraine. It is poorly known as a landscape and garden plant, but seems to have potential for those uses. Compared to ''Crataegus monogyna'', ''C. rhipidophylla'' has larger flowers, larger and more colourful fruits, and more decorative foliage. It has a more or less dome-shaped crown, and it is more tolerant of shade than ''C. monogyna''. Description ''Crataegus rhipidophylla'' is a shrub or tree which can grow to tall. Its stout thorns can be up to 1.5 cm long. Leaf blades are dark green, with 2-4 pairs of acute or subacuminate lobes. A helpful characteristic trait for identification is the finely serrated lobe margin. This can help distinguish ''C. rhipidophylla'' from ''C. monogyna'' which has irregularly serrated lobe margins, with more or less coarse teeth. The basal lobes of flowering shoot ...
