''Ulmus'' × ''hollandica'' 'Klemmer', or Flanders Elm, is probably one of a number of hybrids arising from the crossing of Wych Elm (''Ulmus glabra'') with a variety of Field Elm (''Ulmus minor''), making it a variety of ''Ulmus × hollandica''. Originating in the Bruges area, it was described by Léopold Guillaume Gillekens, Gillekens in 1891 as ''l'orme champêtre des Flandres'' in a paper which noted its local name, ''klemmer'', and its rapid growth in an 1878–91 trial. Royal Botanic Gardens Kew, Kew,Photograph of 'Klemmer' leaves in Kew in Gerald Wilkinson, ''Epitaph for the Elm'', Hutchinson, London 1978 ( / 0-09-921280-3) Augustine Henry, Henry (1913), and Johann Gerd Krüssmann, Krüssmann (1976) listed it as an Ulmus × hollandica, ''Ulmus'' × ''hollandica'' cultivar, though Henry noted its "similarity in some respects" to field elm ''Ulmus minor'', while Peter Shaw Green, Green went as far as to regard it as "possibly ''U. carpinifolia''" (:''minor'').

Etymology
The name 'Klemmer' derives from the Flemish for 'climber', a reference to the tree's rapid growth and lofty height. ''Klemmeri'', used by the Späth nursery among others, is a misnomer, incorrectly implying a proper noun Klemmer. Not to be confused with Ulmus 'Klehmii', 'Klehmii', a cultivar of ''Ulmus americana'' named for Charles Klehm, an Illinois nurseryman.Description
'Klemmer' is a tall, fast growing tree, with a straight cylindrical stem and ascending branches, initially forming a narrow, conical or pyramidal head which later broadens, and producing numerous root-suckers and some epicormic shoots.Photo of Morton Arboretum 'Klemmer' (centre of picture)/ref> The bark, smooth in young trees, is later fissured.

Pests and diseases
'Klemmer' has no significant resistance to Dutch elm disease.Cultivation
Common in western Flanders by the 1880s, before the first Dutch elm disease epidemic, 'Klemmer' was widely supplied and planted in avenues across Belgium and northern France, where it was much esteemed for its timber and rapid growth. Nanot (1885) and Aigret (1905) reported it as planted in the environs of Paris. The Späth nursery of Berlin supplied an ''U. campestris Clemmeri'' to the Dominion Arboretum, Ottawa, Canada, in 1893; by his 1903 catalogue Späth had renamed the cultivar ''U. Klemmeri'', suggesting doubts about its botanical status. The tree was introduced to the USA c.1871, appearing in the catalogues of the Mount Hope Nursery (also known as George Ellwanger, Ellwanger and Patrick Barry (horticulturist), Barry) of Rochester, New York.Notable trees
