The Chinkapin Oak (Quercus muhlenbergii) is an oak in the white oak group (Quercus sect. Quercus). It is native to eastern North America, from Vermont and southern Ontario west to Iowa, south to northwest Florida and eastern Texas, with disjunct populations in west Texas and southeast New Mexico, and eastern Mexico from Coahuila south to Hidalgo.
Image:Chinkapin oak.jpg It is a deciduous tree reaching 30 m tall (exceptionally up to 50 m), with a rounded crown and thin, scaly or flaky bark on the trunk. The leaves resemble those of a chestnut, coarsely toothed, 5-15 cm long and 4-8 cm broad. The acorns are 1.5-2 cm long, and mature in about 6 months after pollination.
The scientific name is commonly spelled muehlenbergii, though the Flora of North America uses the spelling muhlenbergii.
