| Subspecies and varieties |
-- 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' ! -- Q. pseudocerris Boiss. 1853 is a synonym of
Q. cerris, and Q. pseudocerris Rouy 1910 in a non-resolved
name. |
