Tree ID by lateral alternate buds
Terminal buds are formed at the end of the shoot. Lateral buds are formed at the junction of the leaf and shoot. Lateral buds are formed at particular points on the shoot called nodes. If there are 2 buds at each node they are said to be opposite. If there is one bud at each node the buds are said to be alternate as they are in the trees shown here. The Goat Willow has alternate buds that are spirally arranged along the shoot so that leaves do not interfere with each other when they gather light. Many trees, such as Poplars and Willows have alternate spiral buds.
