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.

Meliaceae
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs (and a few herbaceous plants, mangroves) in the order Sapindales. They are characterised by alternate, usually pinnate leaves without stipules, and by syncarpous, apparently bisexual (but actually mostly cryptically unisexual) flowers borne in panicles, cymes, spikes, or clusters. Most species are evergreen, but some are deciduous, either in the dry season or in winter. The family includes about 53 genera and about 600 known species, with a pantropical distribution; one genus (''Toona'') extends north into temperate China and south into southeast Australia, another (''Synoum'') into southeast Australia, and another (''Melia'') nearly as far north. They most commonly grow as understory trees in rainforests, but are also found in mangroves and arid regions. The fossil record of the family extends back into the Late Cretaceous. Uses Various species are used for vegetable oil, soap-making, ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (botany)
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Malesia
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 r ...

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).

Forest Research Institute Malaysia
The Forest Research Institute Malaysia (FRIM; Malay: ''Institut Penyelidikan Perhutanan Malaysia'') is a statutory agency of the Government of Malaysia, under the Ministry of Land, Water and Natural Resources (KATS). FRIM promotes sustainable management and optimal use of forest resources in Malaysia by generating knowledge and technology through research, development and application in tropical forestry. FRIM is located in Kepong, near Kuala Lumpur. FRIM is the world's oldest and largest re-created tropical rain forest. History In 1926, the chief conservator of the forest (equivalent to today's director of forestry), G.E.S Cubitt, asked F.W. Foxworthy to establish a separate forest research unit for the Forestry Department. It was Foxworthy who selected the present site, at Kepong. He was also to become the institute's first chief research officer. The site comprised an area that was practically stripped of its original forest cover except for a few remnant trees at the ...

Azadirachta
''Azadirachta'' is a genus of two species of trees in the family Meliaceae. Numerous species have been proposed for the genus but only two are currently recognized, ''Azadirachta excelsa'' and the economically important tree ''Azadirachta indica'', the Neem tree, from which neem oil is extracted. Both species are native to the Indomalaysian region, and ''A. indica'' is also widely cultivated and naturalized outside its native range. In traditional medicine in India, the resin from the trees have been attributed with medical benefits. A component in the resin is an effective insecticide; see azadirachtin. Another component is an effective anti-fungal; see ''Azadirachta indica''. These species should not be confused with ''Melia azedarach ''Melia azedarach'', commonly known as the chinaberry tree, pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, Indian lilac, or white cedar, is a species of deciduous tree in the mahogany family, Meliaceae, that is nat ...
