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.
