DISTRIBUTION OF THE FOSSIL FLORA OF THE ILLINOIS 
COAL FIELDS. 
The following table enumerates all the species of fossil plants known to this 
time, (March, 1870,) from the Coal Measures of Illinois, and indicates the lo¬ 
cation where the specimens representing them have been found. This synopsis 
of the fossil flora of the Illinois coal fields may serve to elucidate the remarks 
which have been suggested by the study of this flora. The figures marked on 
the table show approximately the proportion of specimens which represent each 
species : 1, for example, for a species represented by less than five specimens ) 
12 for a species represented by one hundred or more.
