An endemic subspecies. Although we have recognised the Turkish tree at subspecific rank, it is doubtful if it can be satisfactorily differentiated from the type subspecies from   N. Iran and the Caucasus. The latter is generally larger in all its parts, with persistent stipules on all buds; it varies considerably less in its characters than does the Turkish tree. Hybrids occur with Q. pubes-cens and Q, petraea s.l.
