Oaks from a folder on this phone. Taken over the past few years. The folder has 185 pics but there are probably many times that unfiled yet. One of the many things I'm studying is the pattern of oak branching from buds and twigs to the overall tree form. It generally occurs in a spiral pattern of 5 buds at each twig end. As it grows, forces of nature in the environment nurture and influence how the spiral of buds matures into unique series of branches. Bark and leaves variations also interest me. These photos are. generally of the bark and characteristic branching forms on mature trees
