22 THE RARITAN FLORA. 



we find the Raritan flora more complex and modern in its com- 

 position than any known Albian flora ; for example, dicotyledons 

 make up 68% of the Raritan flora, while not a single dicotyledon 

 is known from the English Gault, and the representation of this 

 group of plants in the Albian of France and Spain is very meager 

 indeed, and comparable to the display of these plants in the 

 Patapsco formation of Maryland and Virginia, the latter show- 

 ing a striking parallelism with the Albian of the old world, with 

 at least one identical species and closely allied representatives 

 in several identical genera.

 54, as follows:
