406 Platanacce—Platanus. 
1, PLATANUS. 
Characters of the order. Name from aadartvs, broad, in 
allusion to the foliage. 
1. P. orientalis. Common Plane.—The forms of this beau- 
tiful tree are very numerous, differing chiefly in the shape and 
lobing of the leaves. The variety acerifolia is one of 
the commonest in cultivation, frequently bearing the erro- 
neous name of P. occidentalis. It is the form known as the 
London Plane, on account of its being generally planted in 
the parks. An erect-growing tree with usually three-lobed 
leaves, or if 5-lobed less deeply so than in the typical form. 
The typical orientalis is a more spreading tree with very large 
deeply 5-lobed leaves, cordate or truncate at the base. The 
variety cumedta has the leaves distinctly wedge-shaped at 
the base; lacinidta very deeply much divided leaves; and 
variegata variegated foliage. 
2. P. occidentalis. American Plane.—This differs from the 
last in its less deeply lobed more coriaceous pubescent leaves, 
and in the fertile catkins being usually solitary on the long 
peduncles. Itis very rare in British gardens, and not so hardy 
as the Common Plane.
