The wings become less prominent with age". Leaves are small with sharp pointed serratures on the margin, lamina of leaf is unequal at the base and quite long acuminated at the apex.

Pests and diseases The tree is not known to have a resistance to Dutch elm disease.
Cultivation 'Lombartsii', classified as a field elm U. foliacea Gilib., was present in The Hague in the 1930s.Christine Buisman, 'Verslag van de onderzoekingen over de iepenziekte, verricht in het phytopathologisch laboratorium Willie Commelin scholten te Baarn, gedurende 1932 (1)', Tijdschrift over Planteziekte, Vol 39 Iss 4, April 1933, p.82 With no known resistance to Dutch elm disease, 'Lombartsii' is now very rare in Europe. A suberose field elm that stood at the entrance to Brighton Borough Cemetery, Hartington Road, was listed as such by Brighton and Hove Council in 2022, without provenance information.Vivienne Barton, 'Great elms of Brighton and Hove', 2022, bhgreenspaceforum.org Though its leaves were close to 'Lombartsii' herbarium specimens, the tree lacked the pendulous habit of 'Lombartsii'.
