The elm cultivar Ulmus 'Hillieri' arose from a chance seedling at Hillier's Pitt Corner nursery near Winchester, England, in 1918, and was marketed from 1928 as Ulmus hillieri, a name accepted by Christine Buisman in her 1931 labelling of a specimen in France. Since at least 1944 the tree has been determined a form of Ulmus × hollandica, its designation at Kew Gardens, in Green, and in later Hillier catalogues. In 1940, 'Hillieri' was noted as being a hybrid of uncertain origin. Krüssmann notes that for a time the tree was listed by Hilliers as U. × hillieri.

Ulmus laciniata var. nikkoensisRehder, the Nikko elm, was discovered as a seedling near Lake Chūzenji, near Nikkō, Japan, and obtained by the Arnold Arboretum in 1905. The taxonomy of the tree remains a matter of contention, and has been considered possibly a hybrid of U. laciniata and U. davidiana var. japonica. However, in crossability experiments at the Arnold Arboretum in the 1970s, U. laciniata, a protogynous species, was found to be incompatible with U. davidiana var. japonica, which is protandrous.
Ulmus parvifolia, commonly known as the Chinese elm or lacebark elm, is a species native to eastern Asia, including China, India, Japan, Korea, and Vietnam. It has been described as "one of the most splendid elms, having the poise of a graceful Nothofagus".
The Japanese Elm cultivar Ulmus davidianavar.japonica 'Reseda' is an American cultivar raised by the Wisconsin Alumni Research Foundation (WARF) as clone no. 43–8. 'Reseda' was grown from seed sent from Hokkaido, Japan, in the late 1950s. Although not released in its own right, it was destined to become the female parent of the highly successful hybrid cultivars 'New Horizon' and 'Rebona'.
