The Smooth-leaved Elm Ulmus minor var. minor cultivar 'Umbraculifera' was originally cultivated in Iran. The tree is distinguished by its dense, rounded habit, and was once widely planted in Iran as an ornamental, where it occasionally grew to an enormous size. The tree is indistinguishable from U. minor var. minor in all but shape. It 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 [1] [2]. Bean remarked that the tree succeeded well on the continent (Europe) and in eastern North America, but was rarely planted in the UK [3]. 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. The tree is as vulnerable to Dutch elm disease as its siblings; a specimen at the Ryston Hall [3], Norfolk, arboretum, obtained from the Späth nursery before 1914 [4], was killed by the earlier strain of the disease in the 1930s.
