BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 297 
This striking form is unfortunately represented by only two 
specimens both of which are bilobate, although it, like so many 
fossil and existing species of Sterculia, may well have varied 
from entire to trilobate. Among previously described fossil 
forms it may be compared with the Magothy species Sterculia 
minima Berry, a smaller more variable form, or with the Dakota 
sandstone species Sterculia mucronata Lesquereux and Sterculia 
Snowti Lesquereux. The latter while often much larger and 
at times with five lobes is extremely variable. Two named 
varieties have already been recognized and the general character 
and venation of the Tennessee form leads me to conclude that it 
represents another variety of this protean species.

This characteristic species, which was described from the 
Black Creek formation of North Carolina, is also not uncommon 
in the Tuscaloosa formation of Alabama. The present collections 
extend its range upward to the Coffee Sand Member of the Eutaw 
formation in which it occurs at Coffee Bluff, Hardin County, 
Tennessee.
