oak in the white oak group ("Quercus" sect. "Quercus"). It is native to easternNorth America , fromVermont and southernOntario west toIowa , south to northwestFlorida and easternTexas , with disjunct populations in westTexas and southeastNew Mexico , and easternMexico fromCoahuila south to Hidalgo. It is occasionally seen outside its native range with examples atOttawa, Ontario ,Canada , Raleigh,North Carolina and Lake Worth,Florida .It is a
deciduous tree reaching 30 m tall (exceptionally up to 50 m), with a rounded crown and thin, scaly or flakybark on the trunk. The name comes from the resemblance of the leaves to those of achestnut orchinkapin , although they also greatly resemble thechestnut oak orswamp chestnut oak ; coarsely toothed, 5-15 cm long and 4-8 cm broad. Theacorn s are 1.5-2 cm long, and mature in about 6 months after pollination.The scientific name honors
Gotthilf Heinrich Ernst Muhlenberg (1753–1815), aLutheran pastor and amateur botanist inPennsylvania . Because the name may be spelled "Mühlenberg" with an umlaut over the "u", the scientific name is commonly spelled "muehlenbergii". The Flora of North America, however, uses the spelling "muhlenbergii".Chinkapin oak is closely related to the smaller but generally similar dwarf chinkapin oak ("
Quercus prinoides "). Besides the differences in size, the two species can be distinguished by their typical habitat: chinkapin oak is typically found on calcareous soils and rocky slopes while dwarf chinkapin oak is more likely to be found on sandy soils. Although these two oaks are generally regarded as separate species, they are sometimes considered to belong to the same species. Interestingly, when the two are considered to beconspecific , the larger chinkapin oak is often identified as a variety of dwarf chinkapin oak (as "Quercus prinoides "var." acuminata") because the later was described first.Chinkapin oak is also sometimes confused with the related
chestnut oak . However, unlike the pointed teeth on the leaves of the chinkapin oak, the chestnut oak generally has rounded teeth. Unfortunately, this distinction is often not readily apparent. A more reliable means of distinguishing the two is by the bark. Chinkapin oak has a gray, flaky bark very similar towhite oak but with a more yellow-brown cast to it, hence the occasional name yellow oak. Chestnut oak has dark, solid, deeply ridged bark that is very different. The chinkapin oak also has smaller acorns than the chestnut or swamp chestnut oaks, which have some of the largest.Uses
The Chinkapin Oak is especially known for its sweet acorns. Indeed, the nuts contained inside of the thin shell are among the sweetest of any oak; they taste excellent even when eatern raw. These acorns provide an excellent source of food for both wildlife and people. Like the other members of the white oak family, the wood of the Chinkapin oak is a durable hardwood prized for many types of construction. Fact|date=February 2007
