description
The chestnut-leaved oak reaches stature heights of 35, rarely up to 45 meters. The treetop is initially broadly conical and later high and arched. The bark remains smooth for a long time and, with age, forms a bark with flat, strip-like bulges. Young shoots are tomentose and later bald. The buds show remaining stipple scales. The leaves are 8 to 12 centimeters long, narrowly ovate to obovate, with a wedge-shaped to rounded base and 7 to 14 pairs of pointed teeth. Ten to twelve pairs of nerves are formed. The upper side of the leaf is dark green, the underside lighter and more or less covered with star hair. The stem is woolly hairy and 1 to 2.5 inches long. The fruits are 2 to 3 centimeters long, egg-shaped and almost sessile and a quarter to a third of them are surrounded by a fruit cup with awl, protruding or recessed scales. The fruits stand individually or in pairs, rarely in groups of up to five. They mature in the second year.
