This is a beech leaf that I picked from an overhanging branch in The Derwent Valley just yesterday. I was walking with my lady to the ruins of Derwent village which normally sits below the surface of Ladybower Reservoir. She hadn't been there before.
There were many leaves like that one - mostly scattered beneath the trees that bore them. Every autumn leaf is slightly different from the next one and I don't know about you but to me each leaf is rather like a mini work of art - kindly created for us by Mother Nature.
