Fagaceae
Quercus robur
A knotted tree, with many branches and a broad rounded crown that is more or less irregular. Specimens of this tree originating from Roman times can still be found in the Hoge Veluwe National Park (Netherlands). The bark is dark grey and, in old specimens, deeply grooved. Young twigs are reddish-brown. The variable leaves are obovate to elongated oval, 5 - 14 cm long and 4 - 8 cm wide, with 3 to 5 pairs of blunt lobes. The foliage is often densely grouped at the end of the twigs. The leaves emerge brownish-red in the spring. The ovoid to oval acorns grown in groups of from 2 to 6 and are enclosed by the cupule up to a maximum of a third: the cupule is covered with small, triangular, contiguous scales. Q. robur is frequently used in woodlands and on wooded banks. For centuries an important producer of timber.
