The Davey Elm, ''Ulmus × hollandica'' 'Daveyi', is an English cultivar of unknown specific origin, generally restricted to the valleys of Cornwall. Its apparent south-west England provenance, along with its foliage and habit, suggest that it may be a hybrid of Wych Elm and Cornish Elm.〔http://www.cornwall.gov.uk/default.aspx?page=13849〕〔Archie Miles, ''Hidden Trees of Britain'', Ebury Press, 2007, p.17〕 ==Description== The wide-spreading, irregular branches support pendulous branchlets. The leaves are comparatively small, rarely exceeding 6 cm in length by 5 cm wide, with a glabrous upper surface.〔Davey, F. H. (1909). ''Flora of Cornwall''. Reprinted 1978.〕 〔Elwes, H. J. & Henry, A. (1913). ''(The Trees of Great Britain & Ireland )''. Vol. VII. 1848–1929. Republished 2004 Cambridge University Press, ISBN 9781108069380〕 Photographs often show this tree in its windswept coastal form; inland its shape resembles more closely its putative Wych Elm parent, though with a denser crown.〔Cornwall County Council, ''What types of elms are found in Cornwall?''
