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 1.5-4 cm long and 1-2.5 cm broad, which matures in about 1 year
Its bark is grey, finely fissured and becoming crackled. 
The wood is important, used for construction purposes (particularly timber framing), shipbuilding, and for making barrels for wine. Sessile Oak has been designated the national tree of Wales, where it is also called Welsh Oak.
