Quercus lyrata, the overcup oak, is an oak in the white oak group (Quercus sect. Quercus). The common name, overcup oak, refers to its acorns that are mostly enclosed within the acorn cup.[3] It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there.[3] It is a slow-growing tree that often takes 25 to 30 years to mature. It has an estimated lifespan of 400 years.[4]
