Introduction. 



Three years ago I made a preliminary announcement before this 

 Society 1 concerning the fossil floras of southeastern North America. 

 I have, in the interim, completed a monograph of the extensive and 

 especially well preserved plants of the Lower Eocene, and it is some 

 of the results of this detailed study that are given in the present 

 communication. This work has been done under the auspices of the

 There is no part of North America so favorably situated for the 

 study of the floras which preceded the present, extending backward
