Taxonomy
The species was first described by Stanley Larson Welsh in 1986 as Quercus havardii var. tuckeri. It was raised to a full species by R.A. Denham in 2003 using the replacement name Quercus welshii,[4] named after Welsh,[3]: 143 as the name Quercus tuckeri had already been used for a fossil species.[5] Quercus welshii has been included within Quercus havardii, but both morphological and molecular evidence suggests that it is distinct.[6] Quercus welshii is not included in a 2017 list of Quercus species by subgenus and section, but Quercus havardii is placed in Quercus sect. Quercus.[7]
