From Wikipedia, the free encyclopedia
The European White Elm U. laevis cultivar 'Urticaefolia' was raised by Jacques [3] as a chance seedling in 1830, and propagated by grafting. Listed in Revue Hort. 2: 128, 1832 as U. urticaefolia, the tree was described as having deeply toothed leaves, the teeth unequal and very pointed. It was later mentioned by de Vries in Plant Breeding, 1906 [1]. The tree was never grown in the UK [2], and it is unlikely it remains in cultivation elsewhere.
