Origin
Europe

The Wych Elm Ulmus glabra cultivar 'Cornuta' is a little-known tree distinguished only by the one or two cusp-like lobes either side of the apex of the leaf on strong-growing shoots, similar to Ulmus laciniata ^[1]. The tree was finally identified as a cultivar of U. glabra by Boom [2] in Ned. Dendr. 1: 157, 1959 ^[2]. A specimen at the Ryston Hall [3], Norfolk, arboretum, obtained from the Späth nursery (as U. triserrata) before 1914 ^[3], was killed by the earlier strain of Dutch elm disease prevalent in the 1930s. Nevertheless, a very large tree survives at Meise, in Belgium; measured in 2002, it had attained a height of 35 m, and a d.b.h. of @ 1.2m.

'Cornuta' is not known to be available from nurseries.
