Taxonomy Comments: As stated by Fernald (1950), this oak was "chivalrously named [by W.W. Ashe] in 1903 for Margaret Henry Wilcox, who two years later became Mrs. Ashe". There has been controversy, however, over the spelling of the specific epithet; it should be corrected to 'margaretiae' (Weakley & McCormick 2020).
