Description
The Sessile Oak 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 Pedunculate 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.
Comparison with Pedunculate Oak Quercus robur
Significant botanical differences with Pedunulate Oak Quercus robur include the stalked leaves, and the stalkless (sessile) acorns, from which one of its common names is derived. It is found more often than the Quercus robur in upland areas with higher rainfall, but also with lighter soils with better drainage. Hybrids with the Quercus robur are often found, and are named Quercus × rosacea; they are intermediate in characters.
Uses
The wood is important, used for construction purposes (particularly timber framing), shipbuilding, and for making barrels for wine.
Symbology
Sessile Oak has been designated the national tree of Wales, where it is also called Welsh Oak.[2]
