Summary ⁴

Elms are deciduous and semi-deciduous trees comprising the flowering plant genus Ulmus in the plant family Ulmaceae. The genus first appeared in the Miocene geological period about 20 million years ago, originating in what is now central Asia. These trees flourished and spread over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, presently ranging southward across the Equator into Indonesia.

Several species of Elm are found in the area, with the most common being:

• American elm (Ulmus americana)
• Ceder elm (Ulmus crassifolia)

NOTE: Winged elm (Ulmus alata) is a native plant often found near U. crassifolia. Chinese elm (fringed elm) U. crassifolia is ornamental and often escapes into the wild.
