The Sessile Oak (Quercus petraea), also known as Durmast Oak, is a species of oak native to most of Europe, and into Anatolia. It is a large deciduous tree up to 20-40 m tall, in the white oak section of the genus (Quercus sect. Quercus) and similar to the English Oak Q. robur, with which it overlaps extensively in range. The leaves are 7-14 cm long and 4-8 cm broad, evenly lobed with five to six lobes on each side, and a 1 cm petiole. The flowers are catkins, produced in the spring. The fruit is an acorn 2-3 cm long and 1-2 cm broad, which matures in about 6 months. Significant botanical differences with the English Oak include the stalked leaves, and the stalkless (sessile) acorns. It is found more often than the English Oak in upland areas with higher rainfall, but also with lighter soils with better drainage. Hybrids with the English Oak are often found, and are named Quercus × rosacea; they are intermediate in characters.
Uses The wood is important, used for construction purposes, shipbuilding, and for making barrels for wine. | |||||||||||||||||||||||||||||
