A small swelling on a branch or stem, containing an undeveloped shoot, leaf, or flower. Some species have mixed buds containing two of these structures, or even all three.♦ Terminal buds occur at the end of a stem, twig, or branch.♦ Axillary buds, also known as lateral buds, occur in the axils of leaves (in the upper angle of where the leaf grows from the stem).♦ Accessory buds often occur clustered around terminal buds or above and on either side of axillary buds. Accessory buds are usually smaller than terminal and axillary buds.
