Subspecies and
varieties

-- The taxon formerly named Q. x hispanica Lam. 1783, hybrid between Q. cerris and Q. suber must be renamed, following the work of F.M. Vázquez, A. Coombes & al. 2018 ; the new name is Q. x crenata Lam. 1785 : see this word

-- Q. x turneri A.DC (not Willd.) is synonym of Q. x crenata, whereas the species named Q. x turneri Willd. is actually a cultivar (= Quercus 'Turneri') of an artificial hybrid between Q. ilex and Q. robur (see the description here); but for Govaerts & Frodin, 1998, Q. turneri A.DC is synonym of Q. x pseudoturneri C.K.Schneider, while this name is considered everywhere as synonym of the cultivar 'Turneri' !
