DISCUSSION OF THE FLORA 



STATISTICAL VIEW. 



The fossil flora of the John Day Basin, as set forth in the preced- 

 ing pages, is seen to be a rich and interesting one. Although the 

 present enumeration comprises all that is now known regarding the 

 fossil plants, it is probabh' still far from complete, as eveiy collection 

 contains a good proportion of new forms. But as it is in a measure 

 a type locality, it has seemed proper to present a summary of exist- 

 ing knowledge, in order that the information ma}' be made available 

 for use in contiguous and obviously related areas. 



The following table has been prepared for the purpose of bringing 

 out the local distribution and the stratigraphic relationships of the 

 plants:
