THE MAPLE, 349 
A. Negundo (L.), or Ash-leaved Negundo, is a native of the 
United States and of Canada. Although it has been intro- 
duced and cultivated in Britain for nearly two centuries, it is 
a rare tree in Scotland. It grows very fast when young, but 
it seldom exceeds thirty or forty feet im height, and in late 
seasons its vigorous shoots are apt to be killed back by frost. 
It has lately given rise to a new variety, A. N. variegata, 
which on account of its bright white foliage is very attrac- 
tive, and is much sought after. It is readily propagated by 
grafting on any common maple. It is purely an ornamental 
tree.
