Hardiness zone, habitat
Miscellaneous - For A. Camus it is a variety of  Q.pubescens ;
- For O. Schwarz, it is a subspecies of  Q.faginea ;
- For Govaerts & Frodin, and for today's Spanish Authors (Rivas-Martinez, Saenz) it is a hybrid between  Q.canariensis and Q.pubescens subsp subpyrenaica ;
- For many other today's
European Authors, it is a hybrid between Q.pubescens and Q.faginea, which is more matching with morphological chararcters and with the opinion of Camus and Schwarz; but in the opinion of C.Vicioso, Q.pubescens subsp subpyrenaica is actually a hybrid between Q.pubescens and Q.faginea, so everybody is satisfied....
