Ulmus chenmoui is a small deciduous tree from the provinces of Anhui and Jiangsu in eastern China, where it is found at elevations below 200 m. Growing to a maximum height of no more than 20 m, its slender trunk rarely exceeds 0.5 m in diameter at breast height the bark exfoliates in irregular flakes. Its wing-less twigs bear comparatively large obovate to oblong leaves up to 18 cm in length [http://www.asianflora.com/Ulmaceae/Ulmus-chienmoui.htm. The wind-pollinated petal-less flowers are produced on second-year shoots in March; the samaras are obovate < 25 mm long by 17 mm wide and ripen in April. The tree is rare in cultivation in the West, but was evaluated by Mittempergher in Italy, who found it to have a low susceptibility to Dutch elm disease and elm leaf beetle. A specimen at the Sir Harold Hillier Gardens in Hampshire, England, survives in an open location on London Clay. Planted in 1993, it was 7m high and 14 cm d.b.h. in 2005.
