Trees of the genus Platanus are known as Sycamores in North America, and as Planes in England and Australia. They are the sole members of the '''Family Platanaceae.

The seeds of the trees are borne in balls. Typically, the core of the ball is 1 cm in diameter and is covered with a net of mesh 1 mm, which can be peeled off. The ball is 3 cm in diameter and contains several hundred seeds, each of which is conical, with the point attached to the net, and has many thin stiff yellow-green fibers attached to the point.
