Holoptelea Integrifolia
''Holoptelea integrifolia'', the Indian elm or jungle cork tree, is a species of tree in the family Ulmaceae, and a close relative to the true elms (''Ulmus''). It is native to most of Indian subcontinent, Indo-China and Myanmar. It is found mostly on plains but also in mountains on elevations up to 1100 m. Description The Indian elm is a large deciduous tree, about 20–25 m tall (rarely over 30 m), with a broad crown featuring several ascending branches. Bark is grey in colour, covered with blisters, peeling in corky scales on old trees. Leaves are alternately arranged, elliptic-ovate in shape, 8–13 cm long and 3–6.5 cm wide, smooth, with entire margins (occasionally toothed), and a pointed tip. Leaf base is rounded or heart-shaped. Stipules are lance-shaped. Crushed leaves emit an unpleasant odour. Flowers are small, greenish-yellow to brownish, pubescent, borne in short racemes or fascicles at the scars of fallen leaves. Sepals are velvety, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Émile Planchon
Jules Émile Planchon (21 March 1823 – 1 April 1888) was a French botanist born in Ganges, Hérault. Biography After receiving his Doctorate of Science at the University of Montpellier in 1844, he worked for a while at the Royal Botanic Gardens, Kew, Royal Botanical Gardens in London, and for a few years was a teacher in Nancy, France, Nancy and Ghent. In 1853 he became head of the department of botanical sciences at the University of Montpellier, where he remained for the remainder of his career. Planchon was highly regarded in scientific circles, and made a number of contributions in his classification of botanical species and varieties. He is credited with publishing over 2000 botanical names, including ''Actinidia chinensis'', better known as the "golden kiwifruit". Planchon is remembered for his work in saving French grape vineyards from ''Phylloxera vastatrix'', a microscopic, yellow aphid-like pest that was an exotic species from the United States. He performed this ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ulmaceae
The Ulmaceae () are a family of flowering plants that includes the elms (genus ''Ulmus''), and the zelkovas (genus ''Zelkova''). Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia. The family was formerly sometimes treated to include the hackberries, (''Celtis'' and allies), but an analysis by the Angiosperm Phylogeny Group suggests that these genera are better placed in the related family Cannabaceae. It generally is considered to include ca 7 genera and about 45 species. Some classifications also include the genus '' Ampelocera''. Description The family is a group of evergreen or deciduous trees and shrubs with mucilaginous substances in leaf and bark tissue. Leaves are usually alternate on the stems. The leaf blades are simple (not compound), with entire (smooth) or variously toothed margins, and often have an asymmetrical base. The flowers are small and either bisexual or unise ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site at Kew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
