but shows a progressive development of lobes, and is more 
abundant in the later formation. Of the other species of this 
genus two are very large-leaved Cenomanian forms {ravniana 
and fozvueri). In the genus Quercus we find at ClifTwood a 
representative of a Laramie species, another common to the 
Dakota group, a third closely related to the living Quercus 
prinoides Willd. 
Xone of the six ?^Iatawan species of this genus are found 
in the Raritan, in fact the genus is only sparingly represented 
in that formation.
