Description

U. microcarpa can grow to < 30 m in height, with oblong to elliptic leaves < 17 cm long by 8 cm broad borne on extraordinarily corky branchlets bestowing a highly unusual appearance. As its specific epithet implies, the suborbicular samarae are small, < 8 mm across. [1].

Pests and diseases

No information available.

Cultivation

U. microcarpa is very rare in cultivation outside China, and accessions are currently restricted to two arboreta in the USA. In Europe, the species' existence is restricted to three hardwood cuttings grafted onto Wych Elm Ulmus glabra rootstocks by the Bonte Hoek nursery at Glimmen, Netherlands, in 2011.
