Ulmus Pumila 'Pinnato-ramosa'
The Siberian elm cultivar ''Ulmus pumila'' 'Pinnato-ramosa' was raised by Georg Dieck, as ''Ulmus pinnato-ramosa'', at the National Arboretum, Zöschen, Germany, from seed collected for him circa 1890 in the Ili valley, Turkestan (then a region of the Russian Empire, now part of Kazakhstan) by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there.Dieck, G. (1894). ''Neuheiten-Offerten des National-Arboretums zu Zöschen bei Merseburg, 1894/95.''Hansen, N.

Ulmus Pumila
''Ulmus pumila'', the Siberian elm, is a tree native to Asia. It is also known as the Asiatic elm and dwarf elm, but sometimes miscalled the 'Chinese Elm' (''Ulmus parvifolia''). ''U. pumila'' has been widely cultivated throughout Asia, North America, Argentina, and southern Europe, becoming naturalized in many places, notably across much of the United States. Description The Siberian elm is usually a small to medium-sized, often bushy, deciduous tree growing to tall, the diameter at breast height to . The bark is dark gray, irregularly longitudinally fissured. The branchlets are yellowish gray, glabrous or pubescent, unwinged and without a corky layer, with scattered lenticels. The winter buds dark brown to red-brown, globose to ovoid. The petiole is , pubescent, the leaf blade elliptic-ovate to elliptic-lanceolate, , the colour changing from dark green to yellow in autumn.Fu, L., Xin, Y. & Whittemore, A. (2002).

Augustine Henry
Augustine Henry (2 July 1857 – 23 March 1930) was a British-born Irish plantsman and sinologist. He is best known for sending over 15,000 dry specimens and seeds and 500 plant samples to Kew Gardens in the United Kingdom. By 1930, he was a recognised authority and was honoured with society membership in Belgium, Czechoslovakia, Finland, France, and Poland. In 1929 the Botanical Institute of Peking dedicated to him the second volume of ''Icones plantarum Sinicarum'', a collection of plant drawings. In 1935, ''John William Besant'' was to write: 'The wealth of beautiful trees and flowering shrubs which adorn gardens in all temperate parts of the world today is due in a great measure to the pioneer work of the late Professor Henry'.Besant, J. W. (1935) 'Plantae Henryanae', ''Gard. Chron.'' 98 (9 November 1935): 334–335. Early life and education Henry was born on 2 July 1857 in Dundee, Scotland to Bernard (a flax merchant) and Mary (née McManee) Henry; the family returned to ...

Pinnate
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co.

Vasastan, Stockholm
Vasastaden, or colloquially Vasastan, (Swedish for "Vasa town") is a 3.00 km2 large city district in central Stockholm, Sweden, being a part of Norrmalm borough. The major parks in Vasastaden are Vasaparken and Observatorielunden near the centre and Vanadislunden and Bellevueparken in the north. History Vasastaden proper The city district, most likely named after the street Vasagatan, in its turn named after King Gustav Vasa in 1885, was still a peripheral part of the city in the early 1880s. Before the end of that decade, however, some 150 buildings had been built and only the properties along Odengatan remained vacant. The expansion was preceded by a city plan established in 1879, a slightly more modest edition of the 1866 intentions of city planner Albert Lindhagen, in its turn largely a continuation north of an original 17th-century plan. Like the Baroque plan, the new plan took little or no account of local topographic variations, and where the two failed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samara (fruit)
A samara (, ) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus ''Ulmus''), the hoptree (''Ptelea trifoliata''), and the bushwillows (genus ''Combretum''). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus '' Acer'') and ash trees (genus ''Fraxinus''). There are also single-wing samara such as mahogany (genus Swietenia) which have a shape that enables fluttering. Some species that normally produce paired samaras, such as ''Acer pseudoplatanus'', can also produce them in groups of three or four. File:TripleSycamoreS ...

Arboretum National Des Barres
The Arboretum national des Barres (35 hectares) is a national arboretum located in Nogent-sur-Vernisson, Loiret, Centre-Val de Loire, France. It is open daily in the warmer months; an admission fee is charged. Closure is planned for the end of year 2018 because subsidy from local and national government is too short. The Domaine des Barres (283 hectares) was purchased in 1821 by Philippe André de Vilmorin for his studies in forestry. At that time it was almost entirely barren of trees, but Vilmorin planted today's extensive forest, primarily of ''Pinus sylvestris'', '' P. laricio'', and '' P. pinaster'', as well as American oaks. In 1866 his heirs sold 67 hectares to the nation, on which was established a forestry school, and in 1873 Constant Gouet, the arboretum's first director, began the geographic collection on 3 hectares. The Vilmorin family continued to be actively involved, particularly Maurice de Vilmorin, whose shrub collection was given to the state in 1921 following h ...

Späth Nursery
The Späth (often spelt ''Spaeth'') family created one of the world's most notable plant nurseries of the 19th and early 20th centuries. The nursery had been founded in 1720 by Christoph Späth but removed to the erstwhile district of Baumschulenweg (lit. 'nursery way'; now part of the Treptow-Köpenick district) in south-east Berlin in 1863 when Franz Ludwig Späth (1839 - 1913) succeeded his father Ludwig as manager when aged only 25. By the end of the 19th century, the nursery was the largest in the world, occupying 120 hectares. In 1874 Franz built a mansion on the site, now part of Humboldt University and, five years later, established an arboretum. After his death in Britz in 1913, Franz Späth was succeeded by his son, Hellmut, who revived the nursery's flagging fortunes during the Depression by joining the Nazi Party and securing lucrative landscaping contracts for the new autobahns and other public works. However, his outspoken criticism of the Nazi regime saw him i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
