Quercus buckleyi, commonly known as Texas red oak, Buckley's oak, or Spanish oak [4] [5] is a species of flowering plant. [6] [7] It is endemic to the southern Great Plains of the United States (Oklahoma and Texas). [8]
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.[ citation needed ]
