The supposed American elm cultivar Ulmus americana 'Pyramidata' was a Belgian clone listed by Wesmaelkiki.huh.harvard.edu in Bulletin de la Fédération des sociétés d'horticulture de Belgique, 1862, as Ulmus Americana pyramidalis Hort. (with a capital "A").Wesmael, Alfred, Bulletin de la Fédération des sociétés d'horticulture de Belgique 1862: (Ghent, 1863), p.387 It was marketed by the Baudriller nursery, Angers, France, and appeared in their catalogue of 1880 as U. Americana pyramidata. Wesmael's Ulmus americana and Ulmus americana var. variegata, however, do not appear from herbarium specimens to have been American white elm (see Ulmus americana 'Variegata').botanicalcollections.be, specimen BR0000010840726botanicalcollections.be, specimen BR0000010840399 It is known that nurseries in Europe and America marketed the golden wych elm Ulmus glabra 'Lutescens' as Ulmus americana aurea, so it is possible that Wesmael's Ulmus americana pyramidalis was similarly misnamed.
