-- Sub-genus Quercus, Section Quercus, Series Roburoid.
-- This taxon had been considered as a hybrid between Q. canariensis and Q. faginea subspecies broteroi (= Q. x fagineomirbeckii nothosubsp. marianica (Vicioso) Trehane), but for today's Authors (F.M. Vazquez & al.) it is a true species, described under the name : Q. faginea subsp. maroccana (Braun-Blanq. & Maire) F.M. Vázquez & al. 2018 ; more recently, the new molecular analyses performed by Vila-Viçosa & al. 2022 show that this taxon is a synonym or Q. x tlemcenensis
