Ulmus × Hollandica 'Vegeta'
''Ulmus'' × ''hollandica'' 'Vegeta', sometimes known as the Huntingdon Elm, is an old English hybrid cultivar raised at Brampton, near Huntingdon, by nurserymen Wood & Ingram in 1746, allegedly from seed collected at nearby Hinchingbrooke Park. In Augustine Henry's day, in the later 19th century, the elms in Hinchingbrooke Park were ''U. nitens''. Richens, noting that wych elm is rare in Huntingdonshire, normally flowering four to six weeks later than field elm, pointed out that unusually favourable circumstances would have had to coincide to produce such seed: "It is possible that, some time in the eighteenth century, the threefold requirements of synchronous flowering of the two species, a south-west wind" (wych does occur in quantity in Bedfordshire), "and a mild spring permitting the ripening of the samaras, were met." The tree was given the epithet 'Vegeta' by Loudon, a name previously accorded the Chichester Elm by Donn, as Loudon considered the two trees identical. The ...

Ulmus × Hollandica
''Ulmus'' × ''hollandica'' Mill. , often known simply as Dutch elm, is a natural hybrid between Wych elm ''Ulmus glabra'' and field elm ''Ulmus minor'' which commonly occurs across Europe wherever the ranges of the parent species overlap. In England, according to the field-studies of R. H. Richens, "The largest area f hybridizationis a band extending across Essex from the Hertfordshire border to southern Suffolk. The next largest is in northern Bedfordshire and adjoining parts of Northamptonshire. Comparable zones occur in Picardy and Cotentin in northern France". Crosses between ''U.'' × ''hollandica'' and either of the parent species are also classified as ''U.'' × ''hollandica''. ''Ulmus'' × ''hollandica'' hybrids, natural and artificial, have been widely planted elsewhere.Bean, W. J. (1981). ''Trees and shrubs hardy in Great Britain'', 7th edition. Murray, LondonElwes, H.

Dutch Elm Disease
Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by elm bark beetles. Although believed to be originally native to Asia, the disease was accidentally introduced into Americas, America, Europe, and New Zealand. In these regions it has devastated native populations of elms that did not have resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Marie Beatrice Schol-Schwarz, Bea Schwarz and Christine Buisman, who both worked with professor Johanna Westerdijk. The disease affects species in the genera ''Ulmus'' and ''Zelkova''; therefore it is not specific to the Ulmus × hollandica, Dutch elm hybrid. Overview Dutch elm disease (DED) is caused by ascomycete microfungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auckland Zoo
Auckland Zoo is a zoological garden in Auckland, New Zealand, situated next to Western Springs Park not far from Auckland's central business district. It is run by the Auckland Council with the Zoological Society of Auckland as a supporting organisation. Auckland Zoo opened in 1922 experiencing early difficulties mainly due to animal health issues. By 1930 a sizeable collection of animals had been assembled and a zoological society formed. The zoo consolidated during the Second World War and was at that time under the leadership of Lt. Col. Sawer. After the war the collection was expanded, and in the 1950s chimpanzees were acquired to provide tea parties for the public's entertainment, but this practice ceased in 1964. In 1973 the zoo expanded into the adjacent Western Springs park. From the late 1980s to the present day, many old exhibits were phased out and replaced by modern enclosures. In 2011 the zoo opened its largest development, Te Wao Nui, which exhibits native New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southsea Common
Southsea is a seaside resort and a geographic area of Portsmouth, Portsea Island in England. Southsea is located 1.8 miles (2.8 km) to the south of Portsmouth's inner city-centre. Southsea is not a separate town as all of Portsea Island's settlements (including Southsea) were incorporated into the boundaries of Portsmouth in 1904. Southsea began as a fashionable 19th-century Victorian seaside resort named ''Croxton Town'', after a Mr Croxton who owned the land. As the resort grew, it adopted the name of nearby Southsea Castle, a seafront fort constructed in 1544 to help defend the Solent and approaches to Portsmouth Harbour. In 1879, South Parade Pier was opened by Princess Edward of Saxe-Weimar in Southsea. The pier began operating a passenger steamer service across the Solent to the Isle of Wight. This service gave rise to the idea of linking Southsea and its pier to Portsmouth's railway line, and for tourists to bypass the busy town of Portsmouth and its crowded harbou ...

Ulmus × Hollandica 'Cicestria'
The hybrid cultivar ''Ulmus'' × ''hollandica'' 'Cicestria', commonly known as the 'Chichester Elm', was cloned at the beginning of the 18th century from a tree growing at Chichester Hall, Rawreth, near Danbury, Essex, England, then the home of Thomas Holt White FRS, brother of the naturalist Gilbert White. The tree was first recorded by country parson and botanist Adam Buddle in south-east Essex in 1711, & Smith, R.I. (2006). Looking for the Chichester Elm. ''The Professional Gardener'' No. 112, July , 2006. and appeared as ''U. cicestria'' in an 1801 catalogue. 'Cicestria' is the original ''Ulmus × hollandica'' 'Vegeta' ( Lindley, ''Hortus Cantabrigiensis'', 1823), but suffered confusion with the later Huntingdon Elm cultivar by John Claudius Loudon who, without consulting Lindley, accorded the epithet 'Vegeta' to Huntingdon Elm in 1838, as he found the two indistinguishable.Richens, R.

Alan Mitchell (botanist)
Alan F. Mitchell (4 November 1922 – 3 August 1995) was a British forester, dendrologist and botanist, and author of several books on trees. Born in Ilford, Essex, he almost single-handedly measured every notable tree in the British Isles, founding the Tree Register of the British Isles (T.R.O.B.I.), which held records of over 100,000 individual notable trees at the time of his death. During the Second World War, he served with the Fleet Air Arm in the East Asia. Returning by troop ship in the Red Sea at the end of the war, he pondered his future and decided it would be trees. In 1976, the Royal Forestry Society of England, Wales, and Northern Ireland awarded him its Medal for Distinguished Service to Forestry (Gold Medal) during a Society meeting at Westonbirt. (From a tribute by Esmond Harris, ''Quarterly Journal of Forestry'', January 1996, page 67). His 1987 book ''The Guide to Trees of Canada and North America'' is dedicated to his sister Christine.

Camillo Karl Schneider
Camillo Karl Schneider (7 April 1876 – 5 January 1951) was a German botanist and landscape architect. A farmer's son, he was born at Gröppendorf, in the Kingdom of Saxony, and worked as a gardener at Zeitz, Dresden, Berlin and Greifswald. Returning to Berlin to work in the City Parks Department, he assisted in editorial work for the periodical ''Gartenwelt'', which led to his employ as a landscape assistant in Darmstadt and Berlin. In 1900, he moved to Vienna, where he practiced as a freelance architect and writer, travelling extensively through Europe. In 1904 he published his first books, including the beginning of his tome ''Illustrated Handbook of Broad-leaved Trees'', which he completed in 1912. However, the manuscript of what should have been his ''magnum opus'', a study of the genus ''Berberis'', was destroyed in a bombing raid on Berlin in 1943. In 1913, supported by the Austro-Hungarian Dendrological Society, he ventured to China to collect plants and seeds for the bot ...

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 ...

Apetalous
Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Since they include Liliales, an alternative n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Shape
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wych Elm
''Ulmus glabra'' Hudson, the wych elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Urals, and from the Arctic Circle south to the mountains of the Peloponnese and Sicily, where the species reaches its southern limit in Europe; it is also found in Iran. A large deciduous tree, it is essentially a montane species, growing at elevations up to , preferring sites with moist soils and high humidity.Heybroek, H. M., Goudzwaard, L, Kaljee, H. (2009). ''Iep of olm, karakterboom van de Lage Landen'' (:Elm, a tree with character of the Low Countries). KNNV, Uitgeverij. The tree can form pure forests in Scandinavia and occurs as far north as latitude 67°N at Beiarn in Norway. It has been successfully introduced as far north as Tromsø, Norway and Alta, Norway (70°N). It has also been successfully introduced to Narsarsuaq, near the southern tip of Greenland ( 61°N). The tree was by far the most common elm in the north and west of the Britis ...
