Fagaceae (white oak group)

Shrub Live Oak is so uncommon that is usually not shown on Texas plant distribution maps, but it grows in at least three mountain ranges in the Trans-Pecos in west Texas. It is a rigid shrub or small tree that grows at moderate elevations of 4,000 to 4,500 feet in igneous soil on rocky hillsides. It has small, leathery gray-blue evergreen leaves and is extremely drought tolerant. Its acorns ripen very early, sometimes by mid June.
