Buckley's oak is smaller and more likely to be multitrunked than its close relative, the Shumard oak (Q. shumardii). The two species are interfertile, and hybrids are common along a line from Dallas to San Antonio, Texas. Texas red oak usually is 30 to 50 feet (9.1 to 15.2 meters) tall at maturity, and seldom reaches a height of more than 75 feet (23 meters).^[9]

Quercus buckleyi was formerly known as Q. texana, but under botanical rules of priority, that name properly refers to Nuttall's oak.^[3] This has led to much confusion.^[9][10]

It is a highly regarded ornamental and shade tree. In autumn, the leaves turn vivid red and orange.
