BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 65 
ancient lineage and radiation, and only thirty-three, or about 
28 per cent, of the angiosperms have been found in other areas. 
This is still more striking than appears from the bare statement, 
for if Greenland be excluded as near the probable place of origin 
of the Upper Cretaceous floras, or at least the ancient home of 
those of eastern North America, it is seen that only six of the 
angiosperms are common to distant regions such as Europe. 
These six are Dryophyllum gracile, Ficus Krausiana, Magnolia 
Capellini, Euphorbiophyllum antiquum, Cissites crispus and Myrto- 
phyllum angustum. 
The Ripley flora shows a marked relationship to that of the 
antecedent Eutaw formation of this same region, to the Black 
Creek flora of the Carolinas and to the Magothy flora of New 
Jersey and Maryland. This is all the more remarkable in the 
case of the first two when it is realized how small and’ fragmentary 
are the known floras of the Eutaw and Black Creek. Thus 
sixteen of the Ripley species are common to the Eutaw, nineteen 
to the Black Creek and fifteen to the Magothy. The older Tus- 
caloosa flora of the eastern Gulf area has but six species which 
continue on into the Ripley and these are all widely distributed 
types all being common to either Greenland or Europe. It would 
appear that the Ripley flora consists of some few forms resident 
in this region since Tuscaloosa times, with many new elements 
which were added by immigration or evolution in the interval 
between the Tuscaloosa and Ripley. 
In so far as the present records permit a conclusion the Ripley 
flora may be regarded as the culmination of the earlier Cretaceous 
floras of eastern North America. Certain of its species are only 
Ripley species because of the somewhat inconsistent usage of the 
formational name Ripley by geologists. Thus Araucaria bladenen- 
sis and Araucaria Jeffreyi which are so highly characteristic of 
the Black Creek and Eutaw formations are recorded from the 
Ripley formation of Georgia. They have never been found in the 
true Ripley of Alabama, Mississippi or Tennessee, and as I have 
shown elsewhere the Ripley Cusseta sand of Georgia is of the same 
age as the Eutaw Coffee sand of Tennessee. 
There is a considerable number of forms common to the Patoot 
beds of Greenland. Thus eight of the Patoot species are found in
