Ulmus lamellosa, commonly called the Hebei elm, is a small deciduous tree native to four Chinese provinces, Hebei, Henan, Nei Mongol, and Shanxi, to the west and south of Beijing.
A slow growing tree rarely exceeding 10 m in height, U. lamellosa is often multi-stemmed, its upright branches forming a rounded crown, but occasionally forms a single, slender trunk < 20 cm d.b.h. Considered closely related to the Large-fruited Elm U. macrocarpa, it is distinguishable from that species by its mottled, flaking bark and smaller leaves. The leaves, on 3–8 mm petioles, are obovate, < 10 cm long by 5.5 cm wide, caudate at the apex, with simply to doubly serrate margins, and densely pubescent when young; the leaves turn a rich gold in autumn. The perfect wind-pollinated apetalous flowers are produced on second-year shoots in March–April; the large < 35 mm diameter samarae appear from April to May.
