In November 2014, Dr. Richard Spellenberg of New Mexico State University described a new species of White Oak from Northwestern Mexico. While exploring the flora of the northern Sierra Madre Oriental, he and his colleagues had been aware of the plants for some time. Previous collections were usually identified as Quercus toumeyi Sarg. or Q. arizonica Sarg., or as intermediates between these species.
