In has been pointed out in a previous publication that several of 

 the Mesozoic species described by Geyler, 1 Yokoyama, 2 and Nathorst 3 

 are probably identical with European Wealden species. The flora 

 including Bictyozamites, with which we are chiefly concerned, is 

 referred by Dr. Yokoyama to the Bathonian stage of the Inferior 



Geyler (77). 

 Nathorst (90). 



2 Yokoyama (90) & (95).
