97-9 David elm (Ulmus davidiana) is one of several disease-resistant Asian elm species introduced by the Morton Arboretum as a substitute for American elm where Dutch elm disease is a concern. This small elm species was first described in 1873 from the hills north of Beijing, It has thick, deeply corrugated, glossy leaves which turn yellow in the fall. This specimen was given to us by Dr. George Ware, the famous research director in charge of the arboretum’s elm research program, in 1997.
