American-storax, Alligator-wood, Red-gum, Satin-walnut, Sweet-gum

Sweet gum, a tree of the Witch hazel family (Hamamelidaceae), native of the eastern United States, also Mexico and Central America. Along the rivers of the south-eastern United States, Sweet gums exceed 125 ft. in height and 4 ft. in diameter. The deeply cut grey or brownish-grey bark forms winged projections on the twigs. The alternate, palmate, shiny leaves have usually five pointed, finely toothed lobes, and are fragrant when bruised. In the autumn the star-shaped leaves turn brilliant red to purple, making a valuable ornamental tree. The staminate flowers are inconspicuous, the pistillate in spherical heads maturing into long-stalked, globose masses of spiky-tipped capsules. The wood is fine-grained, moderately hard and fairly strong; the heartwood is known as red gum and hazelwood, is variously colored red and brown, the sapwood is paler. From incisions made in the tree a gum exudes which is resinous (storax) and adhesive, and somewhat like white turpentine in appearance, which finally hardens.

Bark and branches

The tree is the peculiar appearance of its small branches and twigs. Bark attaches itself to these in plates edgewise instead of laterally and a piece of leafless branch with aid of little imagination readily takes on reptilian form. The bark is a light brown tinged with red and gray with dark steaks weighing 37 lbs. per cubic foot.

Leaves

Leaves have five sharply pointed palmate lobes, 3-5 inches wide on average and have three distinct bundle scars. Leaves have 6-10 cm petiole. They are rich dark green, shiny, smooth and star-shaped which turns brilliant orange, red and purple colors in autumn. Leaves are 3 to 7 inches broad with glandular serrate teeth. Base is truncated and slightly heart-shaped.
