rather variable taxon, depending on whether Q.cerris or Q.suber
is dominant; consequently, various names have been applied to this species...
Q. x turneri A.DC (not Willd.) is synonym of Q.
x hispanica; 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' !
-- For the same Authors, Q.fontanesii is a hybrid between Q.gussonei and Q.suber, in France and Spain.
-- Q. crenata is strongly threatened with extinction : only ca. 1000 plants remains in Italy, where it is protected, and a few in France. Recent (2018) genetic studies indicate that this taxon may represent the remainder of the ancestral form from which Q. suber evolved, rather than a hybrid between Q. suber and Q. cerris.
