Ulmus 'Frontier' (Ulmus carpinifolia x U. parvifolia)
ULMACEAE (Elm family)

This tree, a hybrid of Ulmus carpinifolia (smooth-leaf elm) and U. parvifolia (Chinese elm), was introduced by the U.S. National Arboretum in 1990. It is highly resistant to Dutch elm disease, and should grow about 25 feet tall, with a spread of 15 feet. The small leaves turn an unusual red-purple in fall. Flowers are rarely seen and the tree does not produce seed. Stanford is experimenting with four of these trees at the end of Escondido Road in front of Stern Hall.
