Sub-genus Quercus, Section Quercus, Series Leucomexicanae; -- Had always been considered as a synonym of Q.leiophylla (= Q. lancifolia), but S. Valencia and A. Coombes 2019 place it at the rank of species, as Q. lancifolia differs in having lustrous leaves on both sides, the margin dentate only on the proximal part, and in being taller (20-27 m); |
