Bought a super new book... "Identification of Trees and Shrubs in Winter using Buds and Twigs" ..by Bernd Schutz. Full of exquisite hand drawn illustrations. I decided I needed to swot up on my winter id of UK trees. But nothing is ever easy. Went to Scone Palace in Perthshire and took clear pics of the buds /leaf scars of this tree. They don't match the book. Now I have lost confidence and am beginning to doubt my id. I will first post the bud/scars. (Later I can add the leaves which were still on the tree.) Based solely on buds what do others think this is?
