Twig Online Tutorials

Look up twig in Wiktionary, the free dictionary.

A twig is a thin, often short, branch of a tree or bush.

The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark are also important, in addition to the thickness and nature of any pith of the twig.^[2]

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 are stubby and slow-growing, with many annular ring markings from seasons past. The twig's age and rate of growth can be determined by counting the winter terminal bud scale scars, or annular ring marking, across the diameter of the twig.
