Quercus kubinyii (KOVATS ex ETTINGSHAUSEN) CZECZOTT vel Q. drymeja UNGER

Pl. 7, Fig. 4–5

Leaves elliptic to ovate, 48 to 110 mm long and 22 to 62 mm wide, apex acute to acuminate, base widely cuneate or rounded, margin simple serrate, teeth acute to spiny, rarely close, sinuses rounded, venation craspedodromous, midrib strong, moderately, straight, secondary veins thin, straight, relatively numerous, alternate, at angles of 30–50°, tertiary veins distinct, alternate percurrent, straight to convex, rarely forked, venation of higher orders regular, polygonal reticulate; areolation well developed or moderately developed, 3- or 4-sided.

The oak foliage assigned to this entity deviates from the standard leaf forms of the indicated fossil species, partly by the finer dentation and partly by the form of the blade. It is difficult to differentiate between Castanea MILLER and Quercus and therefore the taxon was often published as belonging to Castanea ( Knobloch and Kvaček 1976) .
