Enough of this stuff about phones, are you all wannabe drug dealers?
The large oak photographed in my recent TR was easy enough to identify when I had a close look, it is an English oak, or pedunculate oak, Quercus robur because the leaves are without stalks and they have little ears or auricles at their bases.
The other native species, sessile oak, Quercus petraeae has stalked leaves.
@Barewirewalker, many old woods around London, particularly to the north, are principally hornbeam, which used to be cut for firewood.
