Overview. Burr oak, also spelled bur oak, is a tree with many striking features, including crooked branches, large leaves and big acorns.
Most pine trees produce lateral branches in large whorls running up a straight trunk, which make the tree easy to climb. The bark covering the trunk and branches flakes off with large scales. The pine tree releases a strong pine scent when disturbed or overheated.
