Quercus laceyi, the Lacey oak, is a small to medium-size deciduous oak tree which is native to northeastern Mexico (Coahuila and Nuevo León) and to the Texas Hill Country in central Texas in the United States.[3][4]

Quercus laceyi seldom grows more than 35 feet (11 meters) tall, and has a stocky trunk. Its blue-green leaves are oblong and shallowly lobed to unlobed, but shade leaves can be deeply lobed; they most often turn yellow or brown in autumn.[3][5]

Taxonomy

Quercus laceyi has been often confused with Quercus glaucoides, which is an evergreen oak native to central and southern Mexico.[4]
