Ulmus 'Dodoens'
The Dutch hybrid cultivar ''Ulmus'' 'Dodoens' was derived from a selfed seedling of a hybrid of the Exeter Elm ''Ulmus glabra'' 'Exoniensis', and the Himalayan Elm ''Ulmus wallichiana''.〔Heybroek, H. M. (1993). The Dutch Elm Breeding Program. In Sticklen & Sherald (Eds.)(1993). ''Dutch Elm Disease Research'', Chapter 3. Springer Verlag, New York, USA〕 The tree was one of several cultivars prepared for release in 1970, but delayed by the outbreak of the new, aggressive strain of Dutch elm disease.〔Burdekin, D. A. & Rushforth, K. D. (Revised by Webber J. F. 1996). Elms resistant to Dutch elm disease. ''Arboricultural Research Note'' 2/96.
