Hylotelephium Spectabile
''Hylotelephium spectabile'' (synonym (taxonomy), syn. ''Sedum spectabile'') is a species of flowering plant in the stonecrop family (biology), family Crassulaceae, native to China and Korea. Its common names include showy stonecrop, iceplant, and butterfly stonecrop. Description Growing to tall and broad, it is an herbaceous perennial with alternate, simple, toothed leaves on erect, unbranched succulent stems and has a tuber root rhizome. The leaves are usually arranged opposite or in threes, simple and more or less wedge-shaped at the base, and frosted blue above; they are 2.5 to 10 cm long and 0.8 to 5 cm wide. The leaf margin is smooth or serrated towards the tip. Stipules are missing. The star-shaped pink flowers are borne in flat cymes across from summer until first frost. The many-flowered, zymous inflorescence is about 7 to 11 cm wide. The hermaphrodite, radially symmetrical flowers have a diameter of about 1 cm and are usually five-fold. The sepals are about 1 cm lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexandre Boreau
Alexandre Boreau (March 15, 1803 – May 5, 1875) was a French pharmacist and botanist. He is the binomial authority of plants such as '' Polygonum arenastrum'' and '' Pulmonaria longifolia''. Biography Boreau was born in Saumur, in the department of Maine-et-Loire on March 15, 1803. His father was a laborer, and upon his father's death, Boreau worked at baths established on the quay of the Loire, upstream of the Cessart bridge. Still a boy, Boreau came under the protection of his godfather Abel Aubert du Petit-Thouars, an admiral. Boreau was able to study humanities at the college of Saumur. In 1820, he began training to be a pharmacist while working in a dispensary in Angers. Within the framework of these studies, he developed an interest in botany, and he enrolled in courses and studied at the jardin des plantes d'Angers. After his marriage to Antoinette Morin, in 1828, he opened a dispensary in Nevers. He devoted himself to botany and research. He collaborated with Coun ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Hylotelephium
''Hylotelephium'' is a genus of flowering plants in the stonecrop family Crassulaceae. It includes about 33 species distributed in Asia, Europe, and North America. Species in the genus, formerly included in ''Sedum'', are popular garden plants, known as "sedum", "stonecrop", "live-for-ever" or "orpine". Horticulturalists have hybridized many of the species to create new cultivars. Many of the newer ones are patented, so may not be propagated without a license. Taxonomy ''Hylotelephium telephium'' and related species have been considered in a number of different ways since first being described by Linnaeus in 1753, including as a section of ''Sedum'' by Gray in 1821, or a subgenus. But these taxa are quite distinct from Sedum morphologically. ''Hylotelephium'' is one of a group of genera that form a separate lineage from ''Sedum'', and is closely related to ''Orostachys'', '' Meterostachys'', and ''Sinocrassula''. The separation of the genus has not been universally adopted, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytostabilisation
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". The term is an amalgam of the Greek ''phyto'' (plant) and Latin ''remedium'' (restoring balance). Although attractive for its cost, phytoremediation has not been demonstrated to redress any significant environmental challenge to the extent that contaminated space has been reclaimed. Phytoremediation is proposed as a cost-effective plant-based approach of environmental remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and to detoxify various compounds. The concentrating effect results from the ability of certain plants called hyperaccumulators to bioaccumulate chemicals. The remediat ...

Phytopurification
Most organisms involved in water purification originate from the waste, wastewater or water stream itself or arrive as resting spore of some form from the atmosphere. In a very few cases, mostly associated with constructed wetlands, specific organisms are planted to maximise the efficiency of the process. Role of biota Biota are an essential component of most sewage treatment processes and many water purification systems. Most of the organisms involved are derived from the waste, wastewater or water stream itself or from the atmosphere or soil water. However some processes, especially those involved in removing very low concentrations of contaminants, may use engineered eco-systems created by the introduction of specific plants and sometimes animals. Some full scale sewage treatment plants also use constructed wetlands to provide treatment Pollutants in wastewater Pathogens Parasites, bacteria and viruses may be injurious to the health of people or livestock ingesting the p ...

Sedoheptulose
Sedoheptulose or pseudoheptulose or D-''altro''-heptulose is a ketoheptose—a monosaccharide with seven carbon atoms and a ketone functional group. It is one of the few heptoses found in nature, and is found in various fruits and vegetables ranging from carrots and leeks to figs, mangos and avocados. It is an intermediate in respiratory and photosynthetic pathways and plays a vital role in the non-oxidative branch of the pentose phosphate pathway. Studies have shown that 7-O-galloyl-D-sedoheptulose, a chemical extracted from dogwood fruit, is able to reduce pro-inflammatory markers ''in vivo'' such as interleukin-6 (IL-6) and C-reactive protein C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin- ... and thus might be able reduce low-level inflammation in humans. While this comp ...

Division (horticulture)
Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant (usually an herbaceous perennial) is broken up into two or more parts. Both the root and crown of each part is kept intact. The technique is of ancient origin, and has long been used to propagate bulbs such as garlic and saffron. plant tissue culture is also a form of division, where the meristem of the plant is divided. Overview Division is one of the three main methods used by gardeners to increase stocks of plants (the other two are seed-sowing and cuttings). Division is usually applied to mature perennial plants, but may also be used for shrubs with suckering roots, such as gaultheria, kerria and sarcococca. Annual and biennial plants do not lend themselves to this procedure, as their lifespan is too short. Practice Most perennials are best divided and replanted every few years to keep them healthy. They may also be divided in order to produce new plants. Those with woody crow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cultivars
A cultivar is a type of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and when Plant propagation, propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human genetic engineering, 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, 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Epithet
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stylus
A stylus (plural styli or styluses) is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. It can also be a computer accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily. Another widely used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille. Etymology The English word ''stylus'' has two plurals: ''styli'' and ''styluses''. The original Latin word was spelled ; the spelling ''stylus'' arose from an erroneous connection with Greek (), 'pillar'.''Oxford Latin Dictionary'', s.v. "stilus" (2012). The Latin word had several meanings, including "a long, sharply pointed piece of metal; the stem of a plant; a pointed instrument for incising letters; the stylus (as used in literary composi ...
