Ulmus x hollandica is a natural hybrid between Wych Elm U. glabra and Field Elm U. minor that commonly occurs across Europe wherever the ranges of the two parent species overlap. It has also been widely planted elsewhere by Man. The trees and leaves are broadly intermediate between the two species, but resistance to Dutch elm disease is often greater than either's. Notable cultivars include 'Vegeta' (Huntingdon Elm) and 'Major' (Dutch Elm), both once commonly planted throughout the U.K. before the advent of Dutch elm disease.
