The European hop-hornbeam (Ostrya carpinifolia) and the Japanese hop-hornbeam (O. japonica) may reach 21 m (70 feet); the other species are much smaller. The eastern, or American, hop-hornbeam (O. virginiana) is known as ironwood for its hard, heavy wood, used locally for fence posts and small articles such as tool handles.
