Description
The branches ascend to form a broad, pyramidal crown; the leaves bear a vague resemblance to Wych Elm, but are generally smaller, rarely exceeding 10 cm long by 5 cm wide, and thinner in texture.[1]
Pests and diseases
The tree is susceptible to Dutch elm disease.
Cultivation
'Dauvessei' was once grown at Kew Gardens where it attained a height of 13 m.[2] The one specimen surviving in Europe is in Brighton; the tree is grown in Australia, and in the USA, where it can be found along The Mall in Washington D.C. amongst Ulmus americana on either side of the Relecting Pool (2010).

Hybrid cultivars
'Dauvessei' was crossed with Ulmus × hollandica, U. glabra and U. minor subsp. minor in the Dutch elm breeding programme before World War II, but none of the progeny were of particular note and were discarded.[3]
