CURRANT LEAVED MAPLE. 
an approach in habit to the genus Negundo or Box Elder, 
though in other respects different. 
The height of this species is not more than about 3 feet. 
The leaves have petioles longer than themselves. The 
branches are whitish, and smooth, as is every other part of 
the plant ; the leaves of a dark glossy green. The winged 
fruit is small, and in proportion with the reduced stature of 
the species ; having the wings broad even at the base, so 
as to leave between them an unusually small sinus. Bud 
scales broad, ovate, villous within. 
Japan again affords, apparently, an analogous species to 
the present in the Acer trifidum of Thunberg, but in this 
the leaves are also entire as well as trifid, and the divi- 
sions themselves entire. It is also marked as becoming a 
tree.

Leaved Maple, was met with in the Rocky Mountains, by
