Quercus texana, commonly known as Nuttall’s Oak, Texas Red Oak, Spanish Oak or Red River Oak, is native to south east and central USA. In its native habitat it grows in flood plains and poorly drained soils. Quercus texana is synonymous with Quercus nuttallii and Quercus rubra var. texana

The etymological root of the binomial name Quercus is derived from the Latin name for an Oak tree, but some authorities believe it to be derived from the Celtic quer meaning ‘fine’ and cuez meaning ‘a tree’. Texana is derived from the Latin meaning ‘of or from texas’.
