Viola Guestphalica
''Viola guestphalica'', common name high calamine pansy, Westphalia pansy, zinc pansy or (in German) Blaues Galmeiveilchen, is native to the region of northwestern Germany known as Westphalia. It is found in the wild only in the Districts of Paderborn, Hoexter and Hochsauerlandkreis Hochsauerlandkreis (meaning “High Sauerland District” in German) is a Kreis (district) in the east of North Rhine-Westphalia, Germany. Neighboring districts are Soest, Paderborn, Höxter, Waldeck-Frankenberg, Siegen-Wittgenstein, Olpe, M� ..., although it is cultivated in other locations. These are industrial areas where much of the soil is contaminated with lead, zinc and other metals, which some ''Viola'' species are more able to tolerate than some other plants. ''Viola guestphalica'' is in many ways similar to the yellow-flowered '' V. calaminaria'', and long treated as a variety of that species. Recent studies, however, suggest that it should be treated as a separate species. ''Viola g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westphalia
Westphalia (; german: Westfalen ; nds, Westfalen ) is a region of northwestern Germany and one of the three historic parts of the state of North Rhine-Westphalia. It has an area of and 7.9 million inhabitants. The territory of the region is almost identical with the historic Province of Westphalia, which was a part of the Kingdom of Prussia from 1815 to 1918 and the Free State of Prussia from 1918 to 1946. In 1946, Westphalia merged with North Rhine, another former part of Prussia, to form the newly created state of North Rhine-Westphalia. In 1947, the state with its two historic parts was joined by a third one: Lippe, a former principality and free state. The seventeen districts and nine independent cities of Westphalia and the single district of Lippe are members of the Westphalia-Lippe Regional Association (''Landschaftsverband Westfalen-Lippe''). Previous to the formation of Westphalia as a province of Prussia and later state part of North Rhine-Westphalia, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paderborn (district)
Paderborn () is a Kreis (district) in the east of North Rhine-Westphalia, Germany. Neighboring districts are Gütersloh, Lippe, Höxter, Hochsauerland, and Soest. History Paderborn was part of the Bishopric of Paderborn until it was included into Prussia in 1802. After the Napoleonic wars when Prussia created the province Westphalia it also created five districts roughly covering the area of the previous state - Brakel, Büren, Höxter, Paderborn and Warburg. In 1975 Paderborn and Büren districts were merged to the current Paderborn district. At the same time the towns and municipalities in the district were merged to form today's ten towns and municipalities. It is a rural district with urban municipalities. Geography The Paderborn district is located at the western slope of the Teutoburg Forest, west of the Eggegebirge. The highest elevation is on the side of the Totenkopf (498 m) at the district border near Bleiwäsche ( Bad Wünnenberg), the lowest near Delbrück at 77 ...

Höxter (district)
Höxter () is a Kreis (district) in the east of North Rhine-Westphalia, Germany. Neighboring districts are Holzminden, Northeim, Kassel, Waldeck-Frankenberg, Hochsauerland, Paderborn, and Lippe. History The area of the current Höxter district was part of the Bishopric of Paderborn until it was included into Prussia in 1802. In 1816 the new Prussian government created three districts in the area, Höxter, Brakel and Warburg. In 1832 Höxter and Brakel were merged. The present district was created in 1975 when the former districts Warburg and Höxter were merged. At the same time the towns and municipalities in the district were merged to form the today's ten towns. Geography Geographically the district covers the hills east of the Teutoburg Forest, especially the Eggegebirge, and parts of the Weserbergland. The highest elevation is the ''Köterberg'' (Elevation 496 m). The main river is the Weser in the east of the district. Coat of arms The lily in the bottom comes fro ...

Hochsauerlandkreis
Hochsauerlandkreis (meaning “High Sauerland District” in German) is a Kreis (district) in the east of North Rhine-Westphalia, Germany. Neighboring districts are Soest, Paderborn, Höxter, Waldeck-Frankenberg, Siegen-Wittgenstein, Olpe, Märkischer Kreis. The district is named “High Sauerland” because two of the highest mountains of the Sauerland mountainous landscape, Langenberg and Kahler Asten are in its territory. With 2,766 ft / 843 m (Langenberg) and 2,762 ft / 842 m (Kahler Asten) these are also the highest mountains of North Rhine-Westphalia. History The district was established in 1975 in the reorganization of the districts in North Rhine-Westphalia by merging the previous districts Arnsberg, Brilon and Meschede. Geography Geographically the district covers a big part of the Sauerland mountains, including the highest and third highest elevation – the Langenberg near Olsberg with 2,766 ft / 843 m, and the better known Kahler Asten wi ...

Viola Calaminaria
''Viola lutea'' subsp. ''calaminaria'' (synonym ''Viola calaminaria'') is a subspecies of ''V. lutea'', in the violet family, the Violaceae. The plant occurs from Kelmis (''La Calamine'' in French) in the Belgian province of Liège across the borders to Germany and the Netherlands. The plant has adapted to an excess of zinc in the tailings of a former mines, the heaps of stone left over after separating the valuable fraction of ore. By evolving the ability to cope with the toxic heavy metal pollution, this violet has gained an advantage over the other plants in the ecosystem, as is able to become the locally dominant floral component of such habitats. Taxonomy Although it had been reduced to a subspecies in 1986 already, local national species lists preferred to recognise the varieties as locally endemic species, but genetic research in 2006 made this position untenable. Mining for zinc began in earnest regionally in the Roman era, and this violet would most likely have m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthers
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 '' 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'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
