Quercus robur
English Oak
Quercus robur, English Oak or Pedunculate Oak. Natve tree, but uncommon in Redmire except for a few planted individuals. Easily confused with the other native oak, Quercus petraea, and hybrids between the two. Hard, long lasting wood. Trees can live to a very great age and support a greater variety of organisms than any other British tree. The fruits are the familiar acorns, illustrated on this page along with acorns disfigured by the Knopper gall wasp, Andricus quercuscalicis
