A rounded, open, broad-crowned tree to about 10 m tall. Branches ascending but the tips drooping. Leaves 2.5-5 cm long, oblanceolate, grey-green, mostly tapered at the base and having teeth that are characteristically blunt and deep cut. [Ulmus ×viminalis Loudon, in the sense of Melville]
Though usually treated as a cultivar of U. procera this cultivar bears little resemblance to this species. It has also been considered a natural hybrid U. ×viminalis (U. carpinifolia × U. plotii). It is treated here as a cultivar and was once also supplied in a variegated form.
U. glabra 'Crispa' (supplied at the turn of the century by the C.A. Nobelius Nursery of Emerald, Victoria) is very similar to U. 'Viminalis' but with larger, rougher leaves and much more robust stems.
Three trees are known in Victoria growing in Benalla Botanical Gardens; they are mature trees about 14 m tall and previously lopped, 60-80 years old.
