Quercus imbricaria


Quercus imbricaria, the shingle oak, is a deciduous tree in the red oak group of oaks. It is native primarily to the Midwestern and Upper South regions of North America, from southern New York west to northern Illinois and eastern Kansas, and south to central Alabama and Arkansas. It is most commonly found growing in uplands with good drainage, less often along lowland streams, at 100-700 m altitude.

Quercus imbricaria is a medium-sized tree growing to 20 meters (67 feet) tall, with a trunk up to 1 meter (40 inches) in diameter (rarely 1.4 meters, 56 inches). It is distinguished from most other oaks by its leaves, which are shaped like laurel leaves, 8-20 cm (4-10 inches) long and 1.5-7.5 cm (0.6-3.0 inches) broad with an untoothed margin; they are bright green above, paler and somewhat downy beneath. The fruit is an acorn, 9-18 mm long and wide with a shallow cup; they are mature about 18 months after pollination. They are an important food for squirrels and some birds.
