BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 399 
This species was described many years ago by Lesquereux from 
the Dakota sandstone of southern Kansas and subsequently 
reported by Bartsch from the same horizon in Iowa. It is abun- 
dant in the lower Tuscaloosa of western Alabama, and a single 
characteristic specimen is contained in the Arthurs Bluff collection.

STERCULIA LUGUBRIS Lesquereux? 
Sterculia lugubris Lesq. Cret. and Tert. FI. 81. pl. 6. f. 1-3. 1883. 
This species is apparently represented at Arthurs Bluff by the 
single specimen figured, which agrees very well with the Dakota 
group forms of Sterculia lugubris. It is queried since it may 
represent a slender almost parallel-margined form of Aralia 
Wellingtoniana Vaughanii Knowlton, which is so common at this 
locality. (PLATE 31, FIG. x,

Igor, 
This is a trilobate Dakota group species, described originally 
from Kansas and identified by Knowlton in 1901, in a collection 
made at Arthurs Bluff by T. W. Vaughan. 
The present collection contains two fragmentary specimens. 
Which I have little hesitancy in referring to this species, especially 
as it has already been reported from this locality.
