Besides the shrubby willows included in the preceding for- 
mation, there are also shrubberries on dryer ground. These are 
found partly along the edges of the Aspen and Poplar Groves, 
the Willow Swamps and even the pinewoods, partly on dryer 
river-banks, and partly on the hillsides. Though the species of 
shrubs are not so many, the herbaceous flora associated with them 
is richer in species than that of either the woods or the meadows. 
In fact these copses contain many belonging to either and besides 
many of its own. Many of those belonging mainly to the woods 
or to the meadows are here omitted.
