Miscellaneous | --
A. Camus : n° 401; -- Sub-genus Quercus, section Lobatae, Series Erythromexicanae, Group Acutifoliae; -- Hybridizes with Q.salicifolia in Costa-Rica, and with Q.benthamii in Honduras; -- Closely related to Q.sartorii Liebm., species considered as a synonym of Q.xalapensis by S.Romero Rangel 2006, though xalapensis has acorns maturing in 2 years; -- Q. brenesii is often considered as a true species, although closely related (See the Taxonomical revision of Acutifoliae by S. Romero Rangel), differing from Q.cortesii in having fewer secondary veins (7 to 11, showing a "s" shape before entering the teeth) and divergent teeth; also Q. brenesii has a yellowish green colour of the upper side of the blade, with possible amber glandular trichomes. -- Moreover, Q. gracilior (C.H. Muller Misc. Publ. U.S. Dept. Agric. 477: 77 1942) is likely considered as a true species. |
