The Sycamore is among the largest trees in the eastern United States, with the potential to reach 175 feet in height.  Both the trunk and the well-spaced, large, long limbs shed random patches of paper-thin, light tan outer bark, exposing large areas of smooth greenish gray to silver-white bark. The leaves are 4 to 8 inches long and fan-shaped, with three to five toothed lobes with pointed tips.  The upper surface is smooth.  The fruit is a brown ball of closely packed, needlelike seeds.  When the seeds mature, the ball slowly disintegrates, releasing a few seeds at a time until nothing is left but the stems.
