BERRY: MESOzOIC FLORA OF ATLANTIC COASTAL PLAIN 299 
including well marked leaves of a fan-palm; and 69 are dicoty- 
ledons, well distributed among the natural orders and in many 
cases foreshadowing the wonderful display in the rich subtropical 
floras of the Eocene of our southern states. 
It is not worth while in the present brief abstract to present an 
analysis of the botanical character of this flora or the indicated 
ecological conditions, or to trace its members in detail beyond the 
confines of Maryland. A hint of the problems suggested by its 
study is given when it is stated that many of its elements are 
found northward as far as west Greenland in latitude 70°, re- 
appearing on Marthas Vineyard and Block Island and extending 
from Staten Island to the valley of the Potomac, again reappearing 
in North and South Carolina, in western Alabama and again in 
northeastern Texas. 
Tur MATAWAN FLORA 
The Matawan formation, a typically marine series of glauconitic 
sands with marine mollusca, is a unit which has been traced from 
Raritan Bay in New Jersey to the Potomac River. Its deposits 
often show evidence of shallow water origin in their lithologic 
character and in the contained lignite but they have yielded 
practically no fossil plants—a Ficus from New Jersey, fragments of 
undeterminable dicotyledons from Pennsylvania, and the following 
Araucarian cone-scale in Maryland, i. e. Dammara cliffwoodensis. 
This is a species described originally from the Magothy formation 
of New Jersey, one very close to the widespread Dammara borealis 
of Heer. It was found near Millersville in Anne Arundel County 
and is of importance since it would seem to indicate that the 
Magothy flora survived with but little change into at least the 
lower part of the Matawan formation. This fact, while of slight 
interest to the botanist, has this significance, that it helps to ex. 
plain the association of a Magothy-like flora with a Matawan-like 
invertebrate fuana in the coastal plain of the South Atlantic states. 
CONCLUSIONS 
The present contribution is no place for a detailed discussion of 
correlation, nevertheless a statement of the general results of the 
writer’s studies in terms of the standard European section can be 
given in a few words.
