The bark of young twigs is reddish-brown or reddish-black and sometimes silky hairy; later the bark of the branches is bare, brown and shiny. The leaves are simple, alternate, and glabrous, with a petiole long. The blade is long and wide, elliptical to obovate, with a pointed (rarely blunt) tip and a wedge-shaped base.

Vill
Vill is a term used in English history to describe the basic rural land unit, roughly comparable to that of a parish, manor, village or tithing. Medieval developments The vill was the smallest territorial and administrative unit—a geographical subdivision of the hundred and county—in Anglo-Saxon England. It served both a policing function through the tithing, and the economic function of organising common projects through the village moot. The term is the Anglicized form of the word , used in Latin documents to translate the Anglo-Saxon . The vill remained the basic rural unit after the Norman conquest—land units in the ''Domesday Book'' are frequently referred to as vills—and into the late medieval era. Whereas the manor was a unit of landholding, the vill was a territorial one—most vills did ''not'' tally physically with manor boundaries—and a public part of the royal administration. The vill had judicial and policing functions, including frankpledge, as well as resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salix
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dominique Villars or Villar (born 14 November 1745 in Le Villard, part of the commune of Le Noyer, Hautes-Alpes, and died on 26 June 1814 in Strasbourg) was an 18th-century French botanist. His main work is ''Histoire des plantes du Dauphiné'' published between 1786 and 1789, in which about 2,700 species (particularly alpine plants) are described, after over twenty years of observation in the Dauphiné region of southeastern France.

Erich Oberdorfer
Erich Oberdorfer (born 26 March 1905 in Freiburg; died 23 September 2002) was a German biologist specializing in phytosociology and phytogeography. His official botanical author abbreviation is “Oberd." Early life and education Oberdorfer was born in Freiburg. After graduating from high school in 1923, he studied natural sciences at the University of Freiburg and University of Tübingen. In Freiburg he heard lectures from Hans Spemann and Friedrich Oltmann, among others . In addition to Felix Rawitscher, Walter Zimmermann, who was assistant to Friedrich Oltmanns at the time, was one of his teachers. He graduated in Freiburg in 1928 with a doctorate which he wrote under the direction of Friedrich Oltmanns and the ecophysiologist Bruno Huber, about the relationship between the places where different algae grew on the rock faces of the Überlinger See and the light conditions at different depths. Career Oberdorfer initially did not get a job as a teacher because of the economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Temperate Asia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
