The Japanese Zelkova is a medium to large sized deciduous tree growing to 50 plus feet, with a short trunk and an upright vase shape eventually spreading with age. Younger trees show a very upright V habit. Resistant to Dutch Elm disease and is recommended as a replacement for many elms.
Leaves are alternate, simple, lanceolate to narrowly ovate, 1.5 to 2.5" long, with large very uniform serrations. Medium to dark green, sort of dull and much lighter below. Leaf tip is long and pointed.
Fruit are wingless drupes (aren't they all, if they had a wing I think they would be a samara), green turning brown when mature.
Spectacular bark. Like the Chinese Elm, gray with an orange brown inner bark. When young they have lots of lenticels.
They make spectacular bonsai.
Misidentification:
Maybe the Ulmus parviflora, due to the bark and the leaves, but look at the leaves carefully, the serrations are much different.
