Aspidistra Elatior
''Aspidistra elatior'', the cast-iron-plant or bar-room plant, also known in Japanese as ''haran'' or ''baran'' (葉蘭) is a species of flowering plant in the family Asparagaceae, native to Japan and Taiwan. Tolerant of neglect, it is widely cultivated as a houseplant, but can also be grown outside in shade where temperatures remain above . It is used as training material for the ''seika'' form of ''ikebana''. Description Growing to tall and wide, it is an evergreen rhizomatous perennial, with glossy dark green leaves long, and fleshy, 8-lobed cream flowers with maroon colouring on the inner surface, borne in early summer. Pollination According to a study published in 2018, ''A. elatior'' appears to be mainly pollinated by fungus gnats ('' Cordyla sixi'' and ''Bradysia'' spp.'')''. Distribution Although sometimes thought to be of Chinese origin, the species is in fact native to southern Japan, including Kuroshima, Suwanosejima and the Uji Islands. It occurs in associatio ...

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 Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradysia
''Bradysia'' is a genus of fungus gnat in the family Sciaridae.a They are commonly known as darkwinged fungus gnats. They are considered a major pest in greenhouse agriculture because they thrive in the moist conditions common inside greenhouses and feed on the plants being grown within. ''Bradysia'' is a large genus containing over 500 living species, with at least 65 species found in North America and 172 in Europe. ''Bradysia'' species are a major pollinator of plants such as ''Aspidistra elatior''. Species Selected species of ''Bradysia'' include: *'' B. affinis'' (Zetterstedt, 1838) *'' B. alpicola'' ( Winnertz, 1867) *'' B. amoena'' ( Winnertz, 1867) *'' B. angustipennis'' ( Winnertz, 1867) *'' B. angustoocularis'' Mohrig & Krivosheina, 1989 *'' B. aprica'' ( Winnertz, 7) C *'' B. arcula'' Vilkamaa, Salmela & Hippa, 2007 *'' B. atracornea'' Mohrig & Menzel, 1992 *'' B. austera'' Menzel et al., 2006 *'' B. bellingeri'' Shaw, 1953 *'' B. biformis'' (Lundbeck, 1898) *'' B. ...

Aspidistra Lurida
''Aspidistra'' is a genus of flowering plants in the family Asparagaceae, subfamily Nolinoideae, native to eastern and southeastern Asia, particularly China and Vietnam. They grow in shade under trees and shrubs. Their leaves arise more or less directly from ground level, where their flowers also appear. The number of species known has increased considerably from the 1980s onwards, with around 100 accepted . ''Aspidistra elatior'' is common worldwide as a foliage house plant that is very tolerant of neglect. It and other species can also be grown in shade outside, where they are generally hardy to . Description Species of ''Aspidistra'' are perennial herbaceous plants growing from rhizomes. The leaves are either solitary or are grouped in small "tufts" of two to four. They arise more or less directly from the rhizome, rather than being borne on stems. Each leaf has a long stalk ( petiole) and a blade with many veins. The flowering stem ( scape) is usually very short so that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanopsis Sieboldii
''Castanopsis sieboldii'', also known as the Itajii chinkapin or Itajii, is a species of evergreen tree that lives in subtropical eastern Asia. This is a climax species that is commonly found in the Japanese temperate rainforest. Specimens are also present within the forest area of the Tokyo Imperial Palace. ''Castanopsis sieboldii'' was once thought to be a subspecies of the similar ''Castanopsis cuspidata''. Plants and animals associated with this tree include: *''Aspidistra elatior'', the cast-iron plant, grows in the understorey. *''Acrocercops mantica'', ''Chrysocercops castanopsidis'', and ''Lymantria albescens'' larvae of these Asian moths likely mine the leaves. *''Amantis nawai'', a small praying mantis species native to Eastern Asia is known to live around ''C. sieboldii'' where it eats insects. *Okinawa rail The Okinawa rail (''Hypotaenidia okinawae'') is a species of bird in the rail family, Rallidae.

Overstorey
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspe ...

Uji Islands
is a city on the southern outskirts of the city of Kyoto, in Kyoto Prefecture, Japan. Founded on March 1, 1951, Uji is between the two ancient capitals of Nara and Kyoto. The city sits on the Uji River, which has its source in Lake Biwa. Uji has a population of 179,630 and is the second largest city in Kyoto Prefecture. It has an area of 67.54 km2, giving it a population density of 2,660 persons per km2. History In the 4th century the son of Emperor Ōjin established a palace in Uji. Three battles of Uji-gawa took place here in 1180, 1184 and 1221. ''Shōgun'' Ashikaga Yoshimitsu (1358–1408) promoted cultivation of Uji tea in the area. Since then Uji has been an important production and distribution center of superior quality green tea. Tsuen tea has been served since 1160 and is still sold in the oldest tea shop in Japan and possibly the world—the Tsuen tea shop. The final chapters of '' The Tale of Genji'' are set in Uji, attracting visiting literatur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
