Quercus petraea
Quercus petraea, commonly known as the sessile oak, Welsh oak, Cornish oak, Irish oak or durmast oak, is a species of deciduous oak tree in the flowering plant family Fagaceae. It is native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of Ireland, and an unofficial emblem in Wales and Cornwall.
Sessile oak is a significant source of Timber in Europe, and historically was important in ship construction. Most trees reach a height of 20-40 m, and can live for several centuries.
