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 Webbiana Hort., and by Louis van Houtte of Ghent as U. campestris crispa (Webbiana). Henry thought 'Webbiana' a form of Cornish Elm, adding (presumably with Petzold and Kirchner's 1864 description of Loudon's var. concavaefolia in mind) that it "seems to be identical with the insufficiently described U. campestris var. concavaefolia Loudon" – a view repeated by Krüssmann.
