BERRY: MESOZOIC FLORA OF THE COASTAL PLAIN 189 
discovered. A fact of considerable botanical interest is the entire 
absence of any species of Laurus or Salix in North Carolina, both 
genera furnishing a large number and variety of leaves at most 
Cretaceous localities. Thus, there are 10 species of Laurus in 
the Dakota flora besides the allied genera Laurophyllum, Lindera, 
and Malapoenna, and 10 species of Salix. The New Jersey 
Raritan has 5 species of Sa/ix, 1 of Laurus, and 3 of Laurophyl- 
lum. The Magothy has 4 species of Laurus, 1 of Laurophyllum, 
1 of Malapoenna, and 4 of Salix. 
This absence of laurels and willows is also a feature of the 
Tuscaloosa formation in Alabama, one very liable to modification, 
however, when the floras are thoroughly collected and studied. 
Because of their geographical position these beds should be 
provisionally correlated with the Tuscaloosa formation of Alabama ; 
with this reservation, however, that the Tuscaloosa flora, as far as 
it is known, coincides with that of the Raritan. Lithologically 
these North Carolina beds are much more like the Magothy of 
New Jersey, Delaware and Maryland than they are like the Rari- 
tan, and it seems probable that when the problem has been worked 
out for the whole coastal plain it will be found that the Tuscaloosa 
formation of Alabama as a whole includes sediments of Older 
Potomac, Raritan and Magothy age, while what is here called the 
Tuscaloosa formation in North Carolina, already differentiated 
from the Older Potomac, includes phases corresponding to both the 
Raritan and Magothy formations of the more northern portions of 
the coastal plain and to the upper Tuscaloosa and Eutaw forma- 
tions of the Gulf region. 
Except in one or two cases where it seemed desirable, the co- 
pious synonymy has been omitted, although in some instances a 
second citation is added to that of the author of the name in order 
to refer to especially well illustrated material.
