Ulmus macrocarpaHance, the large-fruited elm, is a deciduous tree or large shrub endemic to the Far East excluding Japan. It is notable for its tolerance of drought and extreme cold and is the predominant vegetation on the dunes of the Khorchin sandy lands in the Jilin province of north-eastern China, making a small tree at the base of the dunes, and a shrub at the top.
The Field Elm cultivar Ulmus minor 'Webbiana', or Webb's curly-leaf elm, distinguished by its unusual leaves that fold upwards longitudinally, was said to have been raised at Lee's Nursery, Hammersmith, London, circa 1868, and was first described in that year in The Gardener's Chronicle and The Florist and Pomologist. It was marketed by the Späth nursery of Berlin in the late 19th and early 20th centuries as U. campestris WebbianaHort., and by Louis van Houtte of Ghent as U. campestris crispa (Webbiana). Henry thought 'Webbiana' a form of Cornish Elm, adding that it "seems to be identical with the insufficiently described U. campestris var. concavaefoliaLoudon" – a view repeated by Krüssmann.

The elm cultivar Ulmus 'Myrtifolia', the Myrtle-leaved Elm, first appeared in nursery and horticultural lists from the 1830s, as Ulmus myrtifolia and Ulmus campestris myrtifolia, the name Ulmus myrtifoliaVolxem being used at Kew Gardens from 1880. Lawson's nursery of Edinburgh appears to have been the earliest to list the tree. 'Myrtifolia' was listed by Nicholson in Kew Hand-List Trees & Shrubs (1896), but without description. It was later listed as a cultivar and described by Rehder in 1939 and by Krüssmann in 1962.
The Siberian elm cultivar Ulmus pumila 'Pinnato-ramosa' was raised by Georg Dieck, as Ulmus pinnato-ramosa, at the National Arboretum, Zöschen, Germany, from seed collected for him circa 1890 in the Ili valley, Turkestan by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there. Litvinov (1908) treated it as a variety of Siberian elm, U. pumilavar.arborea but this taxon was ultimately rejected by Green, who sank the tree as a cultivar: "in modern terms, it does not warrant recognition at this rank but is a variant of U. pumila maintained and known only in cultivation, and therefore best treated as a cultivar". Herbarium specimens confirm that trees in cultivation in the 20th century as U. pumilaL. var. arboreaLitv. were no different from 'Pinnato-ramosa'.
