The simple, alternate star-shaped leaf, with its 5 to 7 points or lobes, is 5 to 7 inches across and very aromatic. In the fall its coloring is brilliant, ranging from pale yellow through orange and red to a deep bronze.
The flowers are of two kinds on the same tree, unfolding with the leaves. The fruit at first glance reminds one of the balls of the sycamore, but on closer inspection proves to be a head. It measures an inch or more in diameter and is made up of many capsules with projecting spines. It frequently hangs on the tree by its long swinging stem late into the winter.
The wood is heavy, moderately hard, close-grained, and not durable on exposure. The reddish-brown heartwood, which suggests the name, red gum, is not present to any appreciable extent in logs under 16 inches in diameter. In the South, the wood is extensively used for flooring, interior finish, paper pulp and veneers for baskets of all kinds. Veneers of the heartwood are largely used in furniture, sometimes as imitation mahogany or Circassian walnut. This tree should be more widely planted for ornamental use.
SYCAMORE Platanus occidentalis L.
THE sycamore, also called buttonwood, is considered the largest hardwood tree in North America. It occurs throughout the State, but is most abundant and reaches its largest size along streams and on rich bottom lands. It is one of the more rapidly-growing trees. In maturity it occasionally attains a height of 140 to 170 feet and a diameter of 10 to 11 feet. It often forks into several large secondary trunks, and the massive spreading limbs form an open head sometimes 100 feet across.
