Leaves 5-10(15) cm long, regularly lobed, with wedge-shaped base and leaf stalk up to 2.5 cm long. Leaves develop later than in pedunculate oak. Lateral veins do not usually reach indentations. Monoecious (given tree has flowers of one sex) and wind-pollinated. Female flowers and then acorns in small clusters, sessile or on very short stalks. Nuts (acorns) maturing in Sep.-Oct.
unbanded, ovoid and located in cups. Trees flower in May, as leaves develop.

More warmth-loving than pedunculate, present on poorer soils, e.g. in mixed/coniferous forest, oak woodland and oak-lime-hornbeam forest.
