The tree grows to a height of < 30 m, the trunk < 0.8 m d.b.h. The bark is a brownish grey, and exfoliates in flakes. The coarse leaves are < 20 cm long, narrowly elliptic with an acuminate apex and borne on twigs that occasionally feature corky wings. The wind-pollinated apetalous flowers appear on the second-year twigs in February. The samarae are distinctively shuttle-shaped, < 25 mm in length, on stalks < 22 mm long, and appear in March [1][2].

The species was virtually unknown in the West until it was introduced to the Morton Arboretum, Illinois, in the 1990s as part of an evaluation of Chinese elms for landscape use. [3] [2]. Some of the seedlings raised at the Morton Arboretum were donated to the U S National Arboretum (USNA) in Washington, where they have prospered. No examples are known to grow in Europe; cuttings sent by the USNA to the Bonte Hoek nursery in Glimmen, Netherlands, in 2010 failed to root. The species is not known in Australasia. U. elongata is not known to be in commerce, and there are no known cultivars.
