Rhynchostylis
''Rhynchostylis'' (abbreviated Rhy in the horticultural trade) is a genus in the orchid family (Orchidaceae), closely allied to the genus ''Vanda'' (from which it differs in the one-lobed lip of the flower) and comprising four currently accepted species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines. The name consists of a compound of two Greek elements : ''rhynchos'' 'beak' and ''stylis'' 'column' – in reference to the very broad, fleshy column of the flower. The flowers are borne in dense racemes and are noted for their intense, spicy fragrance. Although lacking in pseudobulbs, the plants have leathery leaves that are drought-resistant. These orchids grow naturally in warm, moist, shaded tropical areas and will thrive in cultivation if given consistent warmth, uniform moisture and bright, but indirect light. Hobbyists wanting to grow them will need a warm, humid growing environment with gentle air movement. They can be grown in p ...

Vanda
''Vanda'', abbreviated in the horticultural trade as ''V.,'' is a genus in the orchid family, Orchidaceae. There are about 87 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers.The Orchids, Natural History and Classification, Robert L. Dressler. ''Vanda'' species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific. Biology The name "Vanda" is derived from the Sanskrit (वन्दाका) name for the species ''Vanda roxburghii'' (a synonym of ''Vanda tessellata''). These mostly epiphytic, but sometimes lithophytic or terrestrial orchids, are distributed in India, Himalaya, Southeast Asia, Indonesia, the Philippines, Ne ...

Rhynchostylis Gigantea
''Rhynchostylis gigantea'' is a species of orchid. This species was first described in 1896 by John Lindley and is native to Borneo, Myanmar, Thailand, Peninsular Malaysia, Laos, Cambodia, Vietnam, China (Hainan) and the Philippines. ''Rhynchostylis'' differs from ''Vanda'' by the one-lobed lip. ''Rhynchostylis'' are also commonly called foxtail orchids because of their long, thin, densely packed inflorescences that get up to with sweetly fragrant blooms. The inflorescences appear in autumn and winter. Due to the wide distribution of ''Rhynchostylis gigantea'', there is a range of different clones: flowers vary slightly in shape and colour (from white to dark red, with spotted forms). Unlike ''Vanda'' species, they need indirect light. ''Rhynchostylis gigantea'' are best grown in a wood-slat basket with little or no potting material and will grow massive fleshy roots entangled throughout the basket if given uniform water and fertilizer A fertilizer (American English) or ...

Rhynchostylis Coelestis
''Rhynchostylis coelestis'' is a species of orchid native to Cambodia, Thailand and Vietnam. The specific epithet ''coelestis'', derived from the Latin ''caelum'' meaning the sky, heavenly, refers to the blue floral colouration. Description These epiphytic herbs form distiched, hard, deeply grooved, arching leaves that are up to 17 cm long and 2 cm wide. The branched stems can grow up to 10-25 cm tall. The 20 to 50 fragrant, white, pink or blue flowers, 2.2 cm wide, are in dense, upright racemes. The spur is flat but the distal half is curved forward. Motes, M. R. (2021). The Natural Genus Vanda. Redland Press. The chromosome count of Rhynchostylis coelestis is 2n=38. Taxonomy The placement of this species within ''Rhynchostylis'' is further disputed, although it is currently an accepted species of the genus.

Orchidaceae
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Ludwig Blume
Charles Ludwig de Blume or Karl Ludwig von Blume (9 June 1796, Braunschweig – 3 February 1862, Leiden) was a German- Dutch botanist. He was born at Braunschweig in Germany, but studied at Leiden University and spent his professional life working in the Dutch East Indies and in the Netherlands, where he was Director of the Rijksherbarium (state herbarium) at Leiden. His name is sometimes given in the Dutch language form Karel Lodewijk Blume, but the original German spelling is the one most widely used in botanical texts: even then there is confusion, as he is sometimes referred to as K.L. Blume (from Karl). He carried out extensive studies of the flora of southern Asia, particularly in Java, then a colony of the Netherlands. From 1823 to 1826 Blume was Deputy Director of Agriculture at the botanic garden in Bogor (Buitenzorg) in Java. In 1827 he became correspondent of the Royal Institute of the Netherlands. In 1855, he was elected a foreign member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiseptic
An antiseptic (from Greek ἀντί ''anti'', "against" and σηπτικός ''sēptikos'', "putrefactive") is an antimicrobial substance or compound that is applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction. Antiseptics are generally distinguished from ''antibiotics'' by the latter's ability to safely destroy bacteria within the body, and from ''disinfectants'', which destroy microorganisms found on non-living objects. Antibacterials include antiseptics that have the proven ability to act against bacteria. Microbicides which destroy virus particles are called viricides or antivirals. Antifungals, also known as antimycotics, are pharmaceutical fungicides used to treat and prevent mycosis (fungal infection). Surgery The widespread introduction of antiseptic surgical methods was initiated by the publishing of the paper '' Antiseptic Principle of the Practice of Surgery'' in 1867 by Joseph Lister, which was inspired by Louis Pasteur ...

Alkaloids
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
