The seeds of the sycamore are borne in balls. 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.
