Miscellaneous 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, though from hybrid origin ( between Q. broteroi and Q. canariensis).
