It is clear from these lists that in this region the species in 
which the individuals become scarcer and scarcer until it fails 
altogether is exceptional. In the majority the individuals are 
abundant in their respective stations up to the very edge of their 
ranges. 
But one who studies the ranges of species in a broad way rather 
than in a restricted area, gets a decided impression that the ranges 
of most species are bordered by a fringe of outlying stations at 
considerable distances from each other. Many of the most 
interesting species of the Sugar Grove region are such outliers. 
Those which are not known elsewhere within approximately one 
hundred miles are listed below. It may be asserted with some 
confidence that some of these such as the Rhododendron and the 
Azalea really do not occur elsewhere within the boundaries of the 
state of Ohio, but some of the others have not yet been searched 
for enough to justify much confidence in their assignment to this 
category. _ One of the list, Silene rotundifolia, occurs in Jackson 
County only twenty-five miles south of our area but as its next 
known station is far beyond the borders of the state, it seems only
