It is native to southeast Europe and southwest Asia, from southern Italy east across the southern Balkans to western Turkey, growing at low to moderate altitudes (up to 1,550 metres or 5,090 feet in the south of the range in southwestern Turkey), in dry areas.[3][4][5]


Description


Quercus trojana is a small to medium-sized tree reaching 10–20 metres (33–66 feet) tall, late deciduous to semi-evergreen, with gray-green leaves 3–7 centimetres (1+1⁄4–2+3⁄4 inches) long and 1.5–4 cm broad with a coarsely serrated margin with sharply pointed teeth. The acorns are 2–4 cm long when mature (about 18 months after pollination) and largely enclosed in the scaly acorn cup.[6]

Fossils of Quercus trojana have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age.[7]
