origin = Iran
The Smooth-leaved Elm "Ulmus minor" var. "minor" cultivar 'Umbraculifera' originated in Iran, where it was once widely planted as an ornamental, and occasionally grew to a great size.

Description

The tree is distinguished by its dense, rounded habit, but is otherwise identical to "U. minor" subsp. "minor".

Pests and diseases

The tree is as vulnerable to Dutch elm disease as the species; a specimen at the Ryston Hall [http://www.rystonhall.co.uk/] , Norfolk, arboretum, obtained from the Späth nursery before 1914 Ryston Hall Arboretum catalogue, circa 1920] , was killed by the earlier strain of the disease in the 1930s.

Cultivation

The tree was introduced to Europe in 1878 by the Späth nursery in Berlin, which had obtained it from a German gardener in the employ of the Shah, and was subsequently planted along streets in Berlin Elwes, H. J. & Henry, A. (1913). "The Trees of Great Britain & Ireland". Vol. VII. pp 1848-1929. Private publication, Edinburgh. [http://fax.libs.uga.edu/QK488xE4/7tgbi/] ] Green, P. S. (1964). Registration of cultivar names in Ulmus. "Arnoldia", Vol. 24. Arnold Arboretum, Harvard University. [http://arnoldia.arboretum.harvard.edu/pdf/articles/1605.pdf] ] . Bean remarked that the tree succeeded well on the continent (Europe) and in eastern North America, but was rarely planted in the UK Bean, W. J. (1981). "Trees and shrubs hardy in Great Britain", 7th edition. Murray, London. ] . Introduced to Australia, the tree was marketed in the early 20th century by the former Gembrook Nursery near Melbourne, but it is not known whether the tree survives in that country.Despite its susceptibility to the disease, it remains in commercial cultivation in Belgium and the Netherlands. The tree is not known to have been introduced to North America.
