BERRY: MESOZOIC FLORA OF ATLANTIC COASTAL PLAIN 411 
This remarkable species was described from the Dakota 
sandstone of Kansas, to which horizon it has hitherto been con- 
fined. It is present at a number of Maryland Raritan localities in 
considerable abundance although for the most part in a rather 
fragmentary condition. 
OccURRENCE: Shannon Hill, Cecil County; Riverside Brick 
Co., Anne Arundel County; East Washington Heights, District 
of Columbia. 
PROTOPHYLLUM MULTINERVE Lesq. 
Protophyllum multinerve Lesq. Fl. Dakota Group tot. pl. 43. f..2; 
pl. 65. f. 1. 1892. 
This species was described from the Dakota sandstone in 
1872 as a species of Pterospermites.* It has not been hitherto 
recorded outside of this horizon in Kansas. It is common in the 
Raritan clays at Cedar Point in Baltimore County, and less abun- 
dantly represented at East Washington Heights, District of 
Columbia. 
PROTOPHYLLUM STERNBERGII Lesq. 
Protophyllum Sternbergii Lesq. Fl. Dakota Group 189. pl. 142. f. I. 
1892. 
This species, like the preceding, has not heretofore been found 
outside the Dakota sandstone of the West, from which it was 
described originally as a species of Pterospermites.} It is found 
to be not uncommon in the Maryland Raritan and is represented 
in collections from Shannon Hill and Bull Mountain in Cecil 
County, and from East Washington Heights in the District of 
Columbia.
