Q. I have some leaves from a tree I would like to
identify. It is roughly 8 to 12 inches in diameter and fairly tall. The leaves
are alternating with lengths of 1.5 to 2 inches long. The leaf stalks are all
really short compared to the leaf length. Can you identify? – M.R., Brookville,
A. This appears to be Ulmus parvifolia –
common name Chinese elm or lacebark elm. This species is quite attractive. It
grows 40-50 feet tall at maturity and has attractive small leaves and
interesting mottled bark. This species is quite adaptable to urban conditions,
and so far, appears to have good resistance to Dutch elm disease and elm leaf
beetles. Do not mistake this species for the inferior Siberian elm (Ulmus
pumila), which is far less ornamental and rather a weedy species.
The Purdue Arboretum has more information about Chinese elm,
