Central London is poor when it comes to showing off the oak tree, especially the two native varieties, the sessile oak and the common oak. The examples that can be found tend all to be fairly young, like the red oaks that we have just seen. This is because the oak tends to need space to flourish and is affected by city grime and pollution. The next tree, however, is a full grown example of a good substitute. It is called the Turkey oak, and I will let you guess from where it originates.

              The bark of the Turkey oak is similar to the common oak. The leaves are similarly lobed, but are longer and thinner. The acorns are roughly like the classic acorn, but are a lot smaller and if you think of an acorn as like an egg cup with an egg in it; only a small amount of the egg appears out of the cup, compared with the normal acorn where more than half of it is visible.
