Pansy
The garden pansy (''Viola'' × ''wittrockiana'') is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section ''Melanium'' ("the pansies") of the genus ''Viola'', particularly '' Viola tricolor'', a wildflower of Europe and western Asia known as heartsease. It is sometimes known as ''Viola tricolor'' var. ''hortensis'', but this scientific name is ambiguous. While ''Viola tricolor'' var. ''hortensis'' Groenland & Rümpler is a synonym of ''Viola'' × ''wittrockiana'', ''Viola tricolor'' var. ''hortensis'' DC. refers to a horticultural variety of wild pansy ('' Viola tricolor'' without interspecific hybridization) that had been illustrated in '' Flora Danica'' in 1777 before the existence of ''Viola'' × ''wittrockiana''. The chromosome number of ''Viola'' × ''wittrockiana'' is 2n = 44–52, with most cultivars being 2n = 48. The flower is in diameter and has two slightly overlapping upper peta ...

Viola (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and f ...

Viola Tricolor
''Viola tricolor'' is a common European wild flower, growing as an annual or short-lived perennial. The species is also known as wild pansy, Johnny Jump up (though this name is also applied to similar species such as the yellow pansy), heartsease, heart's ease, heart's delight, tickle-my-fancy, Jack-jump-up-and-kiss-me, come-and-cuddle-me, three faces in a hood, love-in-idleness, and pink of my john. It has been introduced into North America, where it has spread. It is the progenitor of the cultivated pansy, and is therefore sometimes called wild pansy; before the cultivated pansies were developed, "pansy" was an alternative name for the wild form. It can produce up to 50 seeds at a time. The flowers can be purple, blue, yellow or white. Description ''Viola tricolor'' is a small plant of creeping and ramping habit, reaching at most 15 cm (6 ins) in height, with flowers about in diameter. It grows in short grassland on farms and wasteland, chiefly on acid or neutral soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Pansy
Purple is any of a variety of colors with hue between red and blue. In the RGB color model used in computer and television screens, purples are produced by mixing red and blue light. In the RYB color model historically used by painters, purples are created with a combination of red and blue pigments. In the CMYK color model used in printing, purples are made by combining magenta pigment with either cyan pigment, black pigment, or both. Purple has long been associated with royalty, originally because Tyrian purple dye, made from the mucus secretion of a species of snail, was extremely expensive in antiquity. Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the emperor and aristocracy. According to contemporary surveys in Europe and the United States, purple is the color most oft ...

Wildflower
A wildflower (or wild flower) is a flower that grows in the wild, meaning it was not intentionally seeded or planted. The term implies that the plant probably is neither a hybrid nor a selected cultivar that is in any way different from the way it appears in the wild as a native plant, even if it is growing where it would not naturally. The term can refer to the flowering plant as a whole, even when not in bloom, and not just the flower. "Wildflower" is not an exact term. More precise terms include ''native species'' (naturally occurring in the area, see flora), ''exotic'' or, better, ''introduced species'' (not naturally occurring in the area), of which some are labelled ''invasive species'' (that out-compete other plants – whether native or not), ''imported'' (introduced to an area whether deliberately or accidentally) and ''naturalized'' (introduced to an area, but now considered by the public as native).

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 vari ...

French Language
French ( or ) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the ( Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in 29 countries across multiple continents, most of which are members of the '' Organisation internationale de la Francopho ...

Late Middle English
Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the ''Oxford English Dictionary'' specifies the period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography. Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English language became fragmented, localized, and was, for the most part, being improvised. By the end of the period (about 1470) and aided by the invention of the printing press by Johannes Gutenberg in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aitiology
Etiology (pronounced ; alternatively: aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek (''aitiología'') "giving a reason for" (, ''aitía'', "cause"); and ('' -logía''). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease) and in philosophy, but also in physics, psychology, government, geography, spatial analysis, theology, and biology, in reference to the causes or origins of various phenomena. In the past, when many physical phenomena were not well understood or when histories were not recorded, myths often arose to provide etiologies. Thus, an etiological myth, or origin myth, is a myth that has arisen, been told over time or written to explain the origins of various social or natural phenomena. For example, Virgil's ''Aeneid'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmut Gams
Helmut Gams (1893–1976) was a central European botanist. Born in Brno, he moved to Zürich as a child. He studied at the University of Zurich, being awarded a PhD in 1918. During his career, he worked at the University of Munich and the University of Innsbruck. His research saw him pursue fieldwork around Europe and Asia. He was a geobotanist who specialized in the associations of different species of mosses and lichens with each other and the environment. Gams coined the terms ' biocoenology' and 'phytocoenology Phytosociology, also known as phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together.

Walton-upon-Thames
Walton-on-Thames, locally known as Walton, is a market town on the south bank of the Thames in the Elmbridge borough of Surrey, England. Walton forms part of the Greater London built-up area, within the KT postcode and is served by a wide range of transport links. According to the 2011 Census, the town has a total population of 22,834. The town itself consists mostly of affluent suburban streets, with a historic town centre of Celtic origin. It is one of the largest towns in the Elmbridge borough, alongside Weybridge. History The name "Walton" is Anglo-Saxon in origin and is cognate with the common phonetic combination meaning "Briton settlement" (literally, "Welsh Town" – weal(as) tun). Before the Romans and the Saxons were present, a Celtic settlement was here. The most common Old English word for the Celtic inhabitants was the "Wealas", originally meaning "foreigners" or "strangers".
