Ulmus × hollandica 'Belgica'
The Belgian Elm cultivar ''Ulmus × hollandica'' 'Belgica' became popular throughout Belgium and the Netherlands in the 19th century, both as an ornamental and as a shelter-belt tree. 〔Elwes, H. J. & Henry, A. (1913). ''(The Trees of Great Britain & Ireland )''. Vol. VII. 1848–1929. Republished 2004 Cambridge University Press, ISBN 9781108069380〕
〔Richens, R. H., ''Elm'', Cambridge 1983〕 It was ''the'' 'Hollandse iep' (:'Dutch elm') in these countries, as distinct from the tree known as 'Dutch Elm' in Great Britain and Ireland since the 17th century: ''Ulmus × hollandica'' 'Major'''.〔
==Description==
'Belgica' has a broad crown supported by a straight, rough-barked stem. Unusually thriving on poor sandy soils, it proved one of the fastest-growing elms in Europe, typically achieving heights of < 40 m. The obovate to elliptic leaves are < 12 cm long by 5 cm wide, and terminate at the apex as a long, serrated point. 'Belgica' was prized, among other reasons, for its "ease and grace of twigs and foliage".〔Heybroek, H. M., 'Resistant Elms for Europe' (1982) in ''Research on Dutch Elm Disease in Europe'', HMSO, London 1983〕
