Viola Hispida
''Viola hispida'' is a plant species in the genus ''Viola''. It is endemic in France, and more specifically in the Seine valley. Description This biennial or perennial herb is not higher than 12 cm and has a glabrous stem. The stipule is cut and has an entire central lobe. Like all violets the flowers are zygomorphic. The petals are light violet. The spur is with six to seven millimetres larger than the calyx. The flowering period is from May to June. ''Viola cryana'' was a population described in 1878 by François-Xavier Gillot as an independent species, from a single locality in the French Department Yonne first reported in 1860. This collection was made on small limestone outcrops in the region of Cry southeast of Tonnerre, and accessions of this form remained in cultivation for some time. It is now no longer extant; the population at this location disappeared by 1930. Balouet, J.-C. & Alibert, E.: ''Extinct Species of the World'', Barrons, New York, London, Toronto ...

Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tonnerre, Yonne
Tonnerre () is a Communes of France, commune in the Yonne Departments of France, department in Bourgogne-Franche-Comté in north-central France. Geography Straddling the Canal de Bourgogne, the commune is situated at the following crossroads: *RD 965 (formerly RN 65) linking Auxerre 70 km to the west and Troyes 65 km to the north *RD 905 (formerly RN 5) linking Sens 70 km to the north and Dijon 125 km to the southeast, an historic route from Paris to Geneva. Neighboring communes Toponymy During the Roman era, Tonnerre was known as ''Tornodurum'', which was derived from the Lingone word for "fortress". It was the capital of ''Pagus Tornodorensis''. Here, in the valley of the Armançon, the County of Tonnerre was created, which served as a point of passage between Paris and Dijon, during a time when the King of France had designs on the Duchy of Burgundy. Three etymologies of Tonnerre are rooted in the Celtic era: it is derived from ''Torn'' an obscure ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ...

Departments Of France
In the administrative divisions of France, the department (french: département, ) is one of the three levels of government under the national level ("territorial collectivities"), between the administrative regions and the communes. Ninety-six departments are in metropolitan France, and five are overseas departments, which are also classified as overseas regions. Departments are further subdivided into 332 arrondissements, and these are divided into cantons. The last two levels of government have no autonomy; they are the basis of local organisation of police, fire departments and, sometimes, administration of elections. Each department is administered by an elected body called a departmental council ( ing. lur.. From 1800 to April 2015, these were called general councils ( ing. lur.. Each council has a president. Their main areas of responsibility include the management of a number of social and welfare allowances, of junior high school () buildings and technical staff, ...
