plane-tree
noun[L. platanus.]
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 N. America; it is called also button-wood.
