 case, free, two-lobed and two-celled, with two young 

 seeds in each cell (only one ripening). June.

 Kentucky. 



A shrub six to fifteen feet high, easily distinguished 

 by its bark and leaves from its near relation and frequent 

 neighbor, the Striped Maple (A. Pennsylvdnicum, L.),

 the trees, and which has a similar liking for damp and 

 hilly woods. The latter has larger and differently shaped 

 leaves (Fig. 74, Trees of Northeastern America), and a 

 greenish bark, peculiarly marked lengthwise with stripes.
