Buckley Oak

Quercus buckleyi Nixon & Dorr

Comments

provided by eFloras
For many years the names Quercus texana , Q . rubra var. texana , and Q . shumardii var. texana were erroneously used for Q . buckleyi (L. J. Dorr and K. C. Nixon 1985).

Quercus texana reportedly hybridizes with Q . marilandica (= Q . × hastingsii Sargent). Quercus × hastingsii may be derived from Q . marilandica var. ashei (D. M. Hunt 1989). Hybridization with Q . shumardii may also occur (L. J. Dorr and K. C. Nixon 1985).

Quercus buckleyi

provided by wikipedia EN

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

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 9 to 15 meters (30 to 49 feet) tall at maturity, and seldom reaches a height of more than 23 m (75 ft).[7]

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.[7][8]

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