890 Berry: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 
southern Kansas, so that eventually we will know what are the 
older and what the younger elements in the Dakota flora. 
Seven species in the Arthurs Bluff collection extend northward 
along the Atlantic coastal plain to western Greenland, and four 
additional species in the lists of Woodbine plants quoted from 
Knowlton’s report have a like distribution. These are sufficient 
to indicate that climatic conditions at this time in the Upper 
Cretaceous were much more uniform than they are at the present 
time. A consideration of the large collections from the Tuscaloosa 
formation of Alabama shows that the latter, when compared with 
the contemporaneous Greenland flora, while essentially similar, 
contains additional elements that may legitimately be regarded 
as tropical or subtropical. It seems evident that while the dif- 
ferences in climate between Greenland and Texas were infinitely 
less in Woodbine time than they are today, there was a distinct
