About Quercus buckleyi Nixon & Dorr
Quercus buckleyi Nixon & Dorr, commonly called Texas red oak, Buckley's oak, or Spanish oak, is a species of flowering plant. It is endemic to the southern Great Plains of the United States, where it is found in Oklahoma and Texas. Compared to its close relative Shumard oak (Quercus shumardii), Buckley's oak is smaller and more often grows with multiple trunks. The two species are able to interbreed, and hybrids are common along the route from Dallas to San Antonio, Texas. At maturity, Texas red oak typically grows between 30 and 50 feet (9.1 to 15.2 meters) tall, and it rarely grows taller than 75 feet (23 meters). This species was previously classified under the name Quercus texana, but botanical rules of priority state that this name correctly applies to Nuttall's oak instead. This reclassification has caused a great deal of naming confusion. Texas red oak is a highly valued ornamental and shade tree. In autumn, its leaves turn vivid shades of red and orange.
