are more mesophytic, and on these the kinds of trees are more numerous. 
Sugar maple is an important species, sometimes becoming more abundant 
than the chestnut oak. Other trees which may occur are wild black 
cherry, sweet buckeye, tulip, basswood, Carya microcarpa, shell-bark hick¬ 
ory, black oak and red oak. In such a forest, sugar maple is dominant 
in the undergrowth. The vernal vegetation is richer than on the more 
xerophytic hillsides, and a number of more mesophytic plants are ap¬ 
pearing.
