The elm cultivar Ulmus 'Nemoralis' was listed by Schelle in Beissner et al. (1903), as U. campestris f. nemoralis Hort.[1] Considered "possibly U. carpinifolia (: minor)" by Green.[2]

A sessile-flowering Ulmus nemoralis "from North America" was described by Dumont de Courset in Le botaniste cultivateur (1811),[3] and another, "des bois d'amérique", in the 1831-1832 catalogue of the Audibert brothers' nursery at Tonelle, near Tarascon in France.[4] A Paris herbarium specimen of the latter from the 1830s does not appear to show an American species.[5] European elm cultivars were sometimes referred to by nurseries as "American", probably for marketing reasons (other examples are 'Scampstoniensis',[6][7] 'Vegeta',[8] 'Lutescens',[9] 'Canadensis', and 'Nana'[10]).

Description

Courset's U. nemoralis had oblong, almost smooth, regularly toothed leaves, and sessile flowers.[3] A Ukrainian herbarium specimen labelled U. nemoralis, possibly erroneously, shows Zelkova × verschaffeltii-like leaves.[11]

Cultivation

The tree is not known to remain in cultivation.
