There are two types of twigs: vegetative twigs and fruiting spurs. Fruiting spurs are specialized twigs that generally branch off the sides of branches and leading twigs, and are stubby and slow-growing, with many annular ring markings from seasons past. The age and rate of growth of a twig can be determined by counting the winter terminal bud scale scars, or annular ring marking, down the length of the twig.
