Ulmus minor 'Albo-Dentata'

Ulmus minor 'Albo-Dentata'
Species	Ulmus minor
Cultivar	'Albo-Dentata'
Origin	France

The Field Elm cultivar Ulmus minor 'Albo-Dentata' first featured in the Baudriller (Angers, France) nursery catalogue of 1880 as U. microphylla foliis albo-dentata. It was distributed by the Späth nursery of Berlin in the late 19th and early 20th century, as U. campestris microphylla fol. albo-dentatis.^[1]

Description

Baudriller described the tree simply as a small-leafed elm with silver teeth. It was later described as a small tree, the leaves with white margins and spots.^[2]

Cultivation

One tree, probably obtained from Späth, was planted as U. campestris microphylla fol. albo-dentatis in 1899 at the Dominion Arboretum, Ottawa, Canada.^[3] A specimen of U. campestris microphylla fol. albo-dentatis, obtained from Späth and planted in 1914, stood in the Ryston Hall arboretum, Norfolk,^[4] in the early 20th century, where it was incorrectly listed as U. campestris macrophylla fol. albo dentatis.^[5] No specimens are known to survive, the one known specimen in Latvia now acknowledged as probably another cultivar. The tree is not known to have ever been cultivated beyond Europe.
