Ulmus macrocarpa var. macrocarpa L. K. Fu is distinguished by a "leaf blade abaxially sparsely pubescent, adaxially hirsute or with convex trichome scars, base attenauted to rounded, apex shortly caudate. Samara pubescent, apically concave or rounded, wings thick, stigmas pubescent. Fl. Mar., fr., Apr." The tree is found on hillslopes and in valleys at elevations of between 700 m and 800 m in the Chinese provinces of Anhui, Gansu, Hebei, Heilongjang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Mongol, eastern Qinghai, Shaanxi, Shanxi, Shandong. Beyond China it is also found in Korea, Mongolia, and Russia (Siberia) [1].

Fu [1] sank Ulmus taihangshanensis S.Y.Wang as a synonym for this variety, but the former has more recently been sunk as a synonym of Ulmus lamellosa [2].

The tree is not known to be in cultivation beyond Asia.
