Ulmus × hollandica 'Wentworthii Pendula' (in continental Europe also spelled 'Wendworthii Pendula'), commonly known as the Wentworth Elm or Wentworth Weeping Elm, is a cultivar with a distinctive weeping habit that appears to have been introduced to cultivation towards the end of the 19th century. The tree is not mentioned in either Elwes and Henry's or Bean'sBean, W. J. (1981). Trees and shrubs hardy in Great Britain, 7th edition. Murray, England. classic works on British trees. The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890). At about the same time, the tree was offered for sale by the Späth nursery of Berlin as Ulmus Wentworthi pendula Hort.Späth, L., Catalogue 79 (1890-91; Berlin), p.115Späth nursery, Catalogue 143, p. 135, 1910–11. Berlin, Germany. (see Etymology). The 'Hort.' in Späth's 1890 catalogue, without his customary label "new", confirms that the tree was by then in nurseries as a horticultural elm.John Frederick Wood, F.H.S., in The Midland Florist and Suburban Horticulturist (1851), 6:365, had described an U. Pendula Superba, 'The Superb Weeping Elm', "a really beautiful pendulous tree, with very large foliage, and weeping in the same style as the Weeping Ash". Wood's list distinguishes the tree from weeping wych; the very large leaves and Weeping Ash habit accord with those of 'Wentworthii Pendula'. De Vos, writing in 1889, states that the Supplement to Volume 1 includes entries announced since the main volume in 1887, putting the date of introduction between 1887 and 1889.
