Ulmus × Hollandica 'Pioneer'
The hybrid elm cultivar ''Ulmus × hollandica'' 'Pioneer' is an American clone arising from the crossing of two European species, Wych Elm ''U. glabra'' (female parent) and Field Elm ''U. minor''. Raised by the USDA station at Delaware, Ohio, in 1971, 'Pioneer' was released to commerce in 1983. Description 'Pioneer' is a fast-growing tree distinguished by a dense, globular crown, which as it matures becomes more broad than tall, like its ''U. glabra'' parent, and casting a heavy shade. The leaves are deep green, and similar in shape to the Wych Elm,Santamour, J., Frank, S. & Bentz, S. (1995). Updated checklist of elm (Ulmus) cultivars for use in North America.

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.

Brighton began to attract more visitors following improved road transport to London and becoming a boarding point for boats travelling to France. The town also developed in popularity as a health resort for sea bathing as a purported cure for illnesses. In the Georgian era, Brighton developed as a highly fashionable seaside resort, encouraged by the patronage of the Prince Regent, later King George IV, who spent ...

American Elm
''Ulmus americana'', generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America, naturally occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 ° C (−44 ° F). Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. A prime example of the species was the Sauble Elm, which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. For over 80 years, ''U. americana'' had been identified as a tetraploid, i.e. having double the usual number of chromosomes, making it unique within the genus. However, a study published in 2011 by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
