Masdevallia Davisii
''Masdevallia davisii'', or Davis' masdevallia, is a species of the Orchidaceae, orchid genus ''Masdevallia''. It is also known as the orchid of the sun and was known to the Incas as ''qoriwaqanki'' ("golden waqanki") – due to its similarity in form to the red ''Masdevallia veitchiana'', known as ''waqanki''. It was named after Walter Davis (botanist), Walter Davis who collected it near Cusco in Peru in 1873. Description ''Masdevallia davisii'' is grown cool and blooms in the late spring with a single brilliant yellow flower, usually deep orange inside. The 6.5 to 9 cm flowers hold themselves high and appear successively on an erect, slender Peduncle (botany), peduncle, 25 cm long. The flowers' predominant feature is their thickly textured and well-developed sepals, which end in three characteristic tails (one pointing up and the other two pointing down). Distribution ''Masdevallia davisii'' is found in growing on rocky slopes in Peru at elevations of between 30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Gustav Reichenbach
Heinrich Gustav Reichenbach (Dresden, 3 January 1823 – Hamburg, 6 May 1889) was a botanist and the foremost German orchidologist of the 19th century. His father Heinrich Gottlieb Ludwig Reichenbach (author of ''Icones Florae Germanicae et Helveticae'') was also a well-known botanist. Biography He started his study of orchids at the age of 18 and assisted his father in the writing of ''Icones''. He became a Doctor in Botany with his work on the pollen of orchids (see ‘Selected Works’). Soon after his graduation, Reichenbach was appointed to the post of extraordinary professor of botany at the Leipzig in 1855. He then became director of the botanical gardens at the Hamburg University (1863-1889). At that time, thousands of newly discovered orchids were being sent back to Europe. He was responsible for identifying, describing, classifying. Reichenbach named and recorded many of these new discoveries. He probably was not the easiest of personalities, and used to boast about h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perlite
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing. Properties Perlite softens when it reaches temperatures of . Water trapped in the structure of the material vaporises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m3 (1.1 g/cm3), while typical expanded perlite has a bulk density of about 30–150 kg/m3 (0.03–0.150 g/cm3). Typical analysis *70–75% silicon dioxide: SiO2 *12–15% aluminium oxide: Al2O3 *3–4% sodium oxide: Na2O *3–5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Masdevallia Harryana
''Masdevallia'', abbreviated Masd in horticultural trade, is a large genus of flowering plants of the Pleurothallidinae, a subtribe of the orchid family (Orchidaceae). There are over 500 species, grouped into several subgenera. The genus is named for Jose Masdevall (?-1801), a physician and botanist in the court of Charles III of Spain. Range and morphology These plants are found from Mexico to southern Brazil, but mostly in the higher regions (2,500-4,000 m ASL) of the Andes of Ecuador and Colombia, Peru and Bolivia. They may be epiphytes, terrestrials or growing as lithophytes on damp rocks. The plants are characterized by an abbreviated to elongate and creeping rhizome that gives rise to stems that lack pseudobulbs. The stem bears a single, fleshy, erect to pendent, ovate to lanceolate leaf. The flowers are triangular and occur singly or in racemose inflorescences. They are characterized by a showy calyx and reduced corolla. The sepals are fused at the base and frequentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Gardeners' Chronicle
''The Gardeners' Chronicle'' was a British horticulture periodical. It lasted as a title in its own right for nearly 150 years and is still extant as part of the magazine ''Horticulture Week''. History Founded in 1841 by the horticulturists Joseph Paxton, Charles Wentworth Dilke, John Lindley and the printer William Bradbury it originally took the form of a traditional newspaper, with both national and foreign news, but also with vast amounts of material sent in by gardeners and scientists, covering every conceivable aspect of gardening. Its first editor, John Lindley, was one of the founders. Another founder, Paxton, later also became editor. Prominent contributors included Charles Darwin and Joseph Hooker. By 1851, the circulation of ''The Gardeners' Chronicle'' was given as 6500. Compared with that of the far more eminent ''Observer'' at 6230, and ''The Economist'' at 3826, ''The Gardeners' Chronicle'' did astonishingly well. Possibly these figures include the Chronicle's lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelsea, London
Chelsea is an affluent area in west London, England, due south-west of Charing Cross by approximately 2.5 miles. It lies on the north bank of the River Thames and for postal purposes is part of the south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ''Chelceth'', ''Chelchith' ...

James Veitch & Sons
The Veitch Nurseries were the largest group of family-run plant nurseries in Europe during the 19th century. Started by John Veitch sometime before 1808, the original nursery grew substantially over several decades and was eventually split into two separate businesses—based at Chelsea and Exeter—as it became unfeasible to run the whole operation from one location. Famous plant hunters in the Victorian period employed by the Veitch family include the brothers Thomas Lobb and William Lobb from Cornwall and David Bowman. The Veitch's ability to grow exotic plants is noted in William Jackson Hooker's description of ''Verticordia nitens'', and they were able to supply a specimen for its illustration. The firm had, by the outbreak of the First World War, introduced 1281 plants into cultivation, which were either previously unknown or newly-bred varieties (see cultivars). These included 498 greenhouse plants, 232 orchids, 153 deciduous trees, shrubs and climbing plants, 122 herba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphagnum Moss
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and ericaceous shrubs, as well as orchids and carnivorous plants.Keddy, P ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
