From Wikipedia, the free encyclopedia

Twigs are critically important in identification of trees, shrubs and vines, especially in wintertime. 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 is also important, as is the thickness and nature of any pith of the twig.

There are two types of twig, 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.


Simple English

A twig is a small, thin branch. Twigs are very important in telling apart trees, shrubs and vines, especially in wintertime.
