Pedunculate or English oak Dair ghallda Quercus robur Oak is a deciduous tree, with grey bark. The leaves are lobed with 5 – 6 lobes on either side of the leaf, creating a wavy or puckered margin. The familiar fruit of the oak, an acorn, is borne in autumn. In the Pedunculate oak acorns are carried on 4 – 8cm long stalks (peduncles). While native in Ireland it is uncommon in the wild. That oak was once abundant in Ireland is evident from place names such Kildare, Cill Dara, cill church and dair oak. The word Derry is known as from the city of that name but the word ‘derry’, oak wood or ‘derreen’, little wood, occurs in many townland names in Co. Galway. (Source: Dr Mary Forrest, UCD).
