Cultivar 'Gracilis' | ||
Hybrid parentage U. minor × U. minor 'Plotii' | ||
Ulmus × viminalis 'Gracilis' [:'slender'] is believed to be a hybrid cultivar derived from the crossing U. minor × U. minor 'Plotii'. Cultivars listed as Ulmus gracilis by Kirchner (1864), and as U. scabra viminalis gracilis by Dieck (1885), were considered by Green forms of U. × viminalis. A 1929 herbarium specimen held at the Hortus Botanicus Leiden is labelled U. campestris var. viminalis f. gracilis (see External links below).
