Ulmus glaucescens var. lasiocarpa Rehder, named the Hairy-fruited Glaucescent Elm in the USA, is distinguished by a "samara densely pubescent when young, with scattered hairs when mature. Fl. and fr. March - May."[1]. The tree is found along rivers and mountain slopes at elevations between 2500 m - 2600 m in the provinces of Hebei, Henan, Liaoning, Nei Mongol, Ningxia, eastern Qinghai, and Shanxi; it is not known to have been introduced to Europe but specimens are grown in North America, and in Australia[2] in cool, humid montane conditions near Adelaide.
There are no known cultivars of this taxon, nor is it known to be available from any nurseries.
