FLORA AT THE HORIZON OF THE EAGLE COAL 161 



Plants at the horizon of the Eagle coal. — As indicating the frequent oc- 

 currence of the Pottsville survivors, or of modified forms of Pottsville 

 species, as high as the Eagle coal in the Kanawha formation, I have 

 designated such species with an asterisk in the following listf of plants

A comparison of the Eagle flora with the flora of the Clarion group 

 (p. 149) shows but a very small percentage of identical elements in com- 



f Although the list is" hardly complete, it shows approximately the proportions of the zonal 

 elements. 



J The plant in hand approaches very closely to the Old World type, though it is specifically dif. 

 ferent from the forms from the Anthracite and Northern bituminous basins identified under the 

 same name.
