180 Berry: MEsozorc FLORA OF ATLANTIC COASTAL PLAIN 
another form of the curious genus Dewalguea that is such a 
striking element in the Upper Cretaceous and Lower Eocene. The 
only known American species that resembles this new form in any 
respect is Dewalquea Smithi Berry* of the Tuscaloosa and Black 
Creek formations. The latter is much larger with relatively 
broader leaflets which have less prominently serrate margins and 
partially craspedodrome venation. 
Dewalquea insigniformis is, however, as its name indicates, 
very much like Dewalquea insignis Hosius and V. d. Marck, 
a prominent species in the Campanian and Maestrichtian sub- 
stages of Europe. The latter has relatively broader, less promi- 
nently toothed leaflets, sometimes as many as seven in number, 
and the venation is said to be craspedodrome. The latter is, 
however, a character of slight value since entire and toothed 
leaflets generally occur together and I imagine that Dewalquea 
insignis is merely a serrate form of the associated Dewalquea 
haldemiana Saporta and Marion. If the latter had prominent 
serrate teeth added it would be identical with Dewalquea insigni- 
formis. 
The latter is represented by a large number of fragmentary 
specimens from the upper member of the Bingen sand the most 
perfect of which is shown in solid black in the accompanying figure.
