The elmcultivarUlmus 'Escaillard' was first described by Dumont de Courset in 1811,[1] and listed, without description, as Ulmus escaillard, by the André Leroy nursery at Angers, France, in 1849.[2]
It was distributed by the Baudriller nursery of Angers[3] and by Hesse's nursery, Weener, Germany,[4][5] as U. campestris 'Escaillardii', both nurseries using U. montana for wych elm cultivars. Herbarium specimens from a tree in The Hague obtained from the Hesse nursery label it variously U. glabra 'Escaillardii' and Ulmus × hollandica 'Escaillardi'. The latter was Christine Buisman's determination (1931), identifiable as hers by its handwriting and red label.[6]
