PLANE'-TREE, n. [L. platanus; Fr. plane, platane.]

A tree of the genus Platanus. The oriental plane-tree is a native of Asia; it rises with a straight smooth branching stem to a great highth, with palmated leaves and long pendulous Peduncles, sustaining several heads of small close-sitting flowers. The seeds are downy, and collected into round, rough, hard balls. The occidental plane-tree, which grows to a great highth, is a native of North America; it is called also button-wood and button-tree.
