Elms (genus Ulmus, family Ulmaceae), which first appeared in the Miocene period, originated in central Asia and spread over most of the Northern Hemisphere during the intervening 40 million years.
Dutch elm disease, a fungal disease spread by the elm bark beetle and first identified in the Netherlands during the 1920s, has devastated the elm population by the 1970s in North America and Europe. Resistant elm cultivars are becoming available.

Tulip Poplar, Liriodendron, has been refered to as “canoewood” because it was used by Native Americans in eastern North America to build dugout canoes.
The tulip tree's habit of growing tall and often having no limbs until it reaches 80–100 feet in height make it a valuable timber tree. Tulip trees generally produce large quantities of nectar in their flowers, making it a major honey plant in the eastern United States.
