''Ulmus pumila'' 'Pendula' is from northern China, where it is known as ''Lung chao yü shu'' (: Dragon's-claw elm). It was classified by Frank Meyer in Fengtai in 1908, and introduced to the United States by him from the Peking Botanical Garden as Weeping Chinese Elm. The USDA plant inventory record (1916) noted that it was a "rare variety even in China".Variety Conservation Group, 'Missing or confused cultivars'
/ref> It was confirmed as an ''U. pumila'' cultivar by Krüssmann (1962). Late 19th-century herbarium leaf-specimens suggest that the epithet 'Pendula' has been attached to more than one form of Siberian elm. The name 'Weeping Chinese Elm' is now sometimes used for ''Ulmus parvifolia'' 'Sempervirens', a cultivar of the true Chinese Elm.

Cultivation

Meyer's elm is still cultivated in China, where its asymmetrical, contorted habit is clear even in young specimens. It is more rarely cultivated in Europe and North America; it is said to have been "widely distributed" in the northwestern States. The USDA noted (1916) that it "shows up particularly well when planted on embankments alongside water expanses". The tree probably survives in the Longenecker Horticultural Gardens,
