Plane \Plane\, n. [F., fr. L. platanus, Gr. ?, fr. ? broad; --
   so called on account of its broad leaves and spreading form.
   See {Place}, and cf. {Platane}, {Plantain} the tree.] (Bot.)
   Any tree of the genus Platanus.

   Note: The Oriental plane ({Platanus orientalis}) is a native
         of Asia. It rises with a straight, smooth, branching
         stem to a great height, 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 ({Platanus occidentalis}), which grows to a great
         height, is a native of North America, where it is
         popularly called {sycamore}, {buttonwood}, and
         {buttonball}, names also applied to the California
         species ({Platanus racemosa}).
