Rhus Cotinus
''Cotinus coggygria'', syn. ''Rhus cotinus'', the European smoketree, Eurasian smoketree, smoke tree, smoke bush, Venetian sumach, or dyer's sumach, is a Eurasian species of flowering plant in the family Anacardiaceae. Description It is a multiple-branching deciduous shrub growing to tall with an open, spreading, irregular habit, only rarely forming a small tree. The leaves are long rounded ovals, green with a waxy glaucous sheen. The autumn colour can be strikingly varied, from peach and yellow to scarlet. The flowers are numerous, produced in large inflorescences long; each flower in diameter, with five pale yellow petals. Most of the flowers in each inflorescence abort, elongating into yellowish-pink to pinkish-purple feathery plumes (when viewed en masse these have a wispy 'smoke-like' appearance, hence the common name "smoke tree") which surround the small () drupaceous fruit that develop. Fossil record Macrofossils of ''C. coggygria'' from the early Pliocene epoch have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giovanni Antonio Scopoli
Giovanni Antonio Scopoli (sometimes Latinisation of names, Latinized as Johannes Antonius Scopolius) (3 June 1723 – 8 May 1788) was an Italian physician and natural history, naturalist. His biographer Otto Guglia named him the "first anational European" and the "Carl Linnaeus, Linnaeus of the Austrian Empire". Biography Scopoli was born at Cavalese in the Val di Fiemme, belonging to the Prince-Bishopric of Trent, Bishopric of Trent (today's Trentino), son of Francesco Antonio, military commissioner, and Claudia Caterina Gramola (1699-1791), painter from a patrician family from Trentino.

Paleobiology
Paleobiology (or palaeobiology) is an interdisciplinary field that combines the methods and findings found in both the earth sciences and the life sciences. Paleobiology is not to be confused with geobiology, which focuses more on the interactions between the biosphere and the physical Earth. Paleobiological research uses biological field research of current biota and of fossils millions of years old to answer questions about the molecular evolution and the evolutionary history of life. In this scientific quest, macrofossils, microfossils and trace fossils are typically analyzed. However, the 21st-century biochemical analysis of DNA and RNA samples offers much promise, as does the biometric construction of phylogenetic trees. An investigator in this field is known as a paleobiologist. Important research areas *Paleobotany applies the principles and methods of paleobiology to flora, especially green land plants, but also including the fungi and seaweeds (algae). See also myc ...

Plant Dyes
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Flora Of Azerbaijan
Flora of Azerbaijan or Vegetation of Azerbaijan refers to the plants, trees, flowers which can be found in Azerbaijan. Azerbaijan has a very rich flora, more than 4,500 species of higher plants have been registered in the country. Due to the unique climate in Azerbaijan, the flora is much richer in the number of species than the flora of the other republics of the South Caucasus. About 66% of the species growing in the whole Caucasus can be found in Azerbaijan. The richness of Azerbaijan's flora and the variety of its vegetation results from the variety and richness of its physical-geographic and natural-historic conditions and from its compound history influenced by the remote floristic regions. The floristic areas of Azerbaijan All types of floristic areas- ancient wood, boreal, plain, xerophytic, desert, Caucasian and accidental- exist in Azerbaijan. The representatives of ancient wood type are widely spread in the Talysh region and the location which is suitable for borea ...

Anacardiaceae
The Anacardiaceae, commonly known as the cashew family or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species. Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an irritant. The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus ''Anacardium''), mango, Chinese lacquer tree, yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, smoke tree, marula and cuachalalate. The genus ''Pistacia'' (which includes the pistachio and mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae. Description Trees or shrubs, each has inconspicuous flowers and resinous or milky sap that may be highly poisonous, as in black poisonwood and sometimes foul-smelling.

Fisetin
Fisetin (7,3′,4′- flavon-3-ol) is a plant flavonol from the flavonoid group of polyphenols. It can be found in many plants, where it serves as a yellow/ochre colouring agent. It is also found in many fruits and vegetables, such as strawberries, apples, persimmons, onions and cucumbers. Its chemical formula was first described by Austrian chemist Josef Herzig in 1891. The biological activity of fisetin has been studied in many laboratory assays; like other polyphenols it has many activities. Biological sources Fisetin can be found in a wide variety of plants. It is found in Eudicotyledons, such as trees and shrubs in the family Fabaceae, such as the acacias ''Acacia greggii'' and ''Acacia berlandieri'', the parrot tree ('' Butea frondosa''), the honey locust (''Gleditsia triacanthos''), members of the family Anacardiaceae such as the ''Quebracho colorado'' and species of the genus '' Rhus'', which contains the sumacs. Along with myricetin, fisetin provides the color of the tra ... [...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 ...

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 ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Species
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Tbilisi
Tbilisi ( ; ka, თბილისი ), in some languages still known by its pre-1936 name Tiflis ( ), is the Capital city, capital and the List of cities and towns in Georgia (country), largest city of Georgia (country), Georgia, lying on the banks of the Kura (Caspian Sea), Kura River with a population of approximately 1.5 million people. Tbilisi was founded in the 5th century Anno Domini, AD by Vakhtang I of Iberia, and since then has served as the capital of various Georgian kingdoms and republics. Between 1801 and 1917, then part of the Russian Empire, Tiflis was the seat of the Caucasus Viceroyalty (1801–1917), Caucasus Viceroyalty, governing both the North Caucasus, northern and the Transcaucasia, southern parts of the Caucasus. Because of its location on the crossroads between Europe and Asia, and its proximity to the lucrative Silk Road, throughout history Tbilisi was a point of contention among various global powers.
