574 Berry: MEsozoiIc FLORA OF ATLANTIC COASTAL PLAIN 
Dicotyledonae of the Tuscaloosa formation number 123 species, 
‘distributed in 34 families in 21 orders. The Choripetalae number 
107, the Gamopetalae but 16 forms. 
The flora as a whole is a lowland coastal flora, many of the 
species being strand types. It indicates a land surface of rather 
uniform topography, an abundant and well-distributed rainfall, 
equable temperatures of warm temperate or subtropical type, 
with slight seasonal changes. 
Meager floras are found also in the younger Cretaceous strata 
of the Eutaw and Ripley formations, but these are not included 
in the present contribution.
