Ulmus 'Nana'
The dwarf wych elm cultivar ''Ulmus glabra'' 'Nana', a very slow growing shrub that with time forms a small tree, is of unknown origin. It was listed in the Simon-Louis (Metz, France) 1869 catalogue as ''Ulmus montana nana''. Henry (1913), referring his readers to an account of the Kew specimen in the journal ''Woods and Forests'', 1884, suggested that it may have originated from a witch's broom. It is usually classified as a form of ''Ulmus glabra'' and is known widely as the 'Dwarf Wych Elm'. However, the ancestry of 'Nana' has been disputed in more recent years, Melville considering the specimen once grown at Kew to have been a cultivar of '' Ulmus × hollandica''.Melville, R. (1978).

Ulmus Glabra
''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 ...

Colonization (biology)
Colonisation or colonization is the process in biology by which a species spreads to new areas. Colonisation often refers to ''successful'' immigration where a population becomes integrated into an ecological community, having resisted initial local extinction. In ecology, it is represented by the symbol ''λ'' (lowercase lambda) to denote the long-term intrinsic growth rate of a population. One classic scientific model in biogeography posits that species must continue to colonize new areas through its life cycle (called a '' taxon cycle'') in order to achieve longevity. Accordingly, colonisation and extinction are key components of island biogeography, a theory that has many applications in ecology, such as metapopulations. Scale Colonisation occurs on several scales. In the most basic form, as biofilm in the formation of communities of microorganisms on surfaces. In small scales such as colonising new sites, perhaps as a result of environmental change. And on larger scales w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulmus Glabra 'Lutescens'
The Wych Elm cultivar ''Ulmus glabra'' 'Lutescens', commonly known as the Golden Wych Elm, arose as a sport of a wych found in the York area in the early 19th century by W. Pontey of Pontey's nursery, Kirkheaton, Huddersfield, who propagated and distributed it. The original tree he named the Gallows Elm for its proximity to a gallows near York. Loudon in ''The Gardener's Magazine'' (1839) identified it as a form of ''Ulmus montana'' (:''U. glabra'' Huds.), adding 'Lutescens' by analogy with Corstorphine sycamore, ''Acer pseudoplatanus'' 'Lutescens'. For a time the tree was known in nurseries both in Europe and America as ''U. americana aurea'', probably on account of its shape, and for marketing reasons. Not to be confused with two other popular cultivars named 'Golden Elm', ''Ulmus × hollandica'' 'Wredei' and ''Ulmus'' 'Louis van Houtte'. Description A medium-sized, fast-growing deciduous tree that reaches a height of approximately 15 m with a spread of about 20 ...

Ulmus 'Scampstoniensis'
The elm cultivar ''Ulmus'' 'Scampstoniensis', the Scampston Elm or Scampston Weeping Elm, is said to have come from Scampston Hall, Yorkshire, England, before 1810. Loudon opined that a tree of the same name at the Royal Horticultural Society's Garden in 1834, high at 8 years old "differed little from the species" (i.e. the smooth-leaved elm, his ''U. glabra'' Ulmus_minor.html"_;"title="''Ulmus_minor">''Ulmus_minor''_._''Ulmus_minor''_.html"_;"title="Ulmus_minor.html"_;"title="''Ulmus_minor">''Ulmus_minor''_">Ulmus_minor.html"_;"title="''Ulmus_minor">''Ulmus_minor''_._Augustine_Henry">Henry_described_the_tree,_from_a_specimen_growing_in_ ''Ulmus_minor''_.html"_;"title="Ulmus_minor.html"_;"title="''Ulmus_minor">''Ulmus_minor''_">Ulmus_minor.html"_;"title="''Ulmus_minor">''Ulmus_minor''_._Augustine_Henry">Henry_described_the_tree,_from_a_specimen_growing_in_Victoria_Park,_Bath">Victoria_Park,_Bath,_Somerset.html" ;"title="Victoria_Park,_Bath.html" "title="Augustine_Henry.html" " ...

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 ...

Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
