Ulmus × Hollandica 'Serpentina'
The putative hybrid cultivar ''Ulmus × hollandica'' 'Serpentina' is an elm of unknown provenance and doubtful status. Henry identified it as intermediate between ''U. glabra'' and ''U. minor'', a view accepted by Bean and by Melville, who believed that the specimens at Kew bearing the name 'Serpentina' were ''U. glabra'' "introgressed by ''U. carpinifolia''" ''U. minor''and were similar to but "distinct from 'Camperdownii'". Koch had listed an ''U. serpentina'' in 1872, and an ''U. montana serpentina'' was marketed in the late 19th century by the Baudriller nursery of Angers, the Späth nursery of Berlin, and the Ulrich nursery of Warsaw.Ulrich, C. (1894), ''Katalog Drzew i Krezewow, C. Ulrich'', Rok 1893-94, Warszawa In Späth catalogues between c.1890 and 1920, however, though 'Serpentina' appears, 'Camperdownii' is absent; by 1930 'Camperdownii' appears but 'Serpentina' is absent. This suggests that 'Serpentina' may have been a continental name for 'Camperdownii', and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Dominion Arboretum
The Dominion Arboretum (french: Arboretum du Dominion) is an arboretum part of the Central Experimental Farm of Agriculture and Agri-Food Canada in Ottawa, Ontario, Canada. Originally begun in 1889, the Arboretum covers about of rolling land between Prince of Wales Drive, Dow's Lake and the Rideau Canal. Carleton University is located at the opposite side of the Canal. At a latitude of 45°, it can experience extremely hot and humid summers and extremely cold winters. It displays a wide range of well-established trees and shrubs with the intention of evaluating their hardiness, including 1,700 different species and varieties. The arboretum is open from dawn to dusk and the admission is free. Although the climate of the Ottawa area is Zone 5a, the topography of the Arboretum produces a microclimate and is warmer by one zone. This has allowed for a collection of magnolias, azaleas, and several other fringe trees including Metasequoia and Liriodendron. One of the favourit ...

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] |
Ulmus × Hollandica 'Major'
''Ulmus'' × ''hollandica'' 'Major' is a distinctive cultivar that in England came to be known specifically as ''the'' Dutch Elm, although all naturally occurring Field Elm ''Ulmus minor'' × Wych Elm '' U. glabra'' hybrids are loosely termed 'Dutch elm' ( ''U.'' × ''hollandica''). It is also known by the cultivar name 'Hollandica'. Nellie Bancroft considered 'Major' either an F2 hybrid or a backcrossing with one of its parents.Bancroft, H. 1934. Notes on the status and nomenclature of the British elms. V. – Elms generally accepted as hybrids, the Dutch Elm. ''The Gardeners’ Chronicle'', 96: 298-299. According to Richens the tree was a native of Picardy and northern France, where it was known from the fifteenth to nineteenth centuries as ''ypereau'' or ''ypreau''.Richens, R. H., (1983).

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). On the discrimination of species in hybrid swarms with special reference to ''Ulmus'' and the nomenclature of ''U. minor'' (Mill.) and ''U. carpinifolia'' (Gled.). ''Taxon'' 27: 345-351.

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'.

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 '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" " ...
