Twigs

Twigs grow in a variety of shapes, colors and sizes. Some twigs are stout while others are thin, some may be hairy while others are not, and some have large buds while others have small buds. Twigs offer valuable clues about the identity of a tree, especially in the winter.  Below are a few of the many types of twigs. Continue to Bark >>>

 
Maple lateral buds, leaf scars and twigs are all oppositely arranged. Sugar maple twigs are brown, slender and shiny with very sharp terminal buds. Catalpa twigs show a whorled arrangement - there are three leaf scars and buds at each node. Oaks have multiple end buds. White oak twigs are red-brown to somewhat gray, hairless, with rounded and hairless buds. Twigs are often shiny or somewhat waxy.
Black locust has obvious paired spines. Spines are modified leaves. The twigs are angular, zig-zag and red-brown to gray in color. Honey locust (not shown) has modified twigs called thorns. Ginkgo, apples, and cherry trees have obvious spur shoots. These shoots usually bear flowers/fruit and only grow a few millimeters each year. Winged elm twigs are slender, hairless, slightly zigzag, reddish-brown, with red-brown buds. Twigs have conspicuous corky wings that protrude one-half inch.
Walnut twigs are very stout, have leaf scars that resemble monkey faces, pale buds, and a very distinctive chambered pith.   
Yellow-poplar buds have only two bud scales - they are valvate. Another interesting feature of yellow-poplar twigs are the stipule scars that surround the twigs. Stipules are a modified leaf.
Some twigs are covered with obvious hairs. Staghorn sumac is a good example of this.
