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'', the wych elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Ural Mountains, 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 altitudes 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 Municipality in Norway. It has been successfully introduced as far north as Tromsø and Alta in northern Norway (70°N). It has also been successfully introduced to Narsarsuaq, near the southern tip of Greenland ( 61°N).

Colonization (biology)
Colonisation or colonization is the spread and development of an organism in a new area or habitat. Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local community. In ecology, it is represented by the symbol ''λ'' (lowercase lambda) to denote the long-term intrinsic growth rate of a population. Surrounding theories and applicable process have been introduced below. These include dispersal, colonisation-competition trade off and prominent examples that have been previously studied. One classic scientific model in biogeography posits that a species must continue to colonize new areas through its life cycle (called a ''taxon cycle'') in order to persist. Accordingly, colonisation and extinction are key components of island biogeography, a theory that has many applications in ecology, such as metapopulations. Another factor included in this scientific model is the competition-colonisation trade off. This idea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missouri Botanical Garden
The Missouri Botanical Garden is a botanical garden located at 4344 Shaw Boulevard in St. Louis, Missouri.

Ulmus Glabra 'Lutescens'
The Wych Elm cultivar ''Ulmus glabra'' 'Lutescens', commonly known as the Golden Wych Elm, arose as a sort 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'.

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'' Henry described the tree, from a specimen growing in Victoria Park, Bath, Somerset">Bath, as "a weeping form of ''U. nitens''" [:''Ulmus minor'' ]; however Green considered it "probably a form of ''Ulmus × hollandica''". Writing in 1831, Loudon said that the tree was supposed to have originated in America. ''U. minor'' is not, however, an American species, so if the tree was brought from America, it must originally have been taken there from Europe. There was (and is) an 'American Plantation' (or 'America Plantation') at Scampston, which may be related to this supposition. A number of old specimens of 'Scampstoniensis' i ...

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. ...
