Contributions to the Mesozoic flora of the Atlantic coastal 
plain—IV. Maryland * 
EDWARD W. BERRY 
( WITH PLATE 8) 
The present contribution is devoted to a brief description of 
some recent additions to the flora of the Magothy formation in the 
state of Maryland. The Magothy formation, arenaceous in this 
region and more or less argillaceous to the northeastward, has been 
found to contain an abundant flora. From beds of this age in New 
Jersey the writer has recorded 114 different species of fossil plants. 
In 1906 a brief contribution made known 41 species of fossil plants 
from beds of this age in Delaware and Maryland. The exact 
localities were Deep Cut on the C. & D. Canal just east of the 
Maryland state line with 32 species ; Grove Point in Cecil County, 
Md., with 25 species; and Good Hope Hill near Washington in the 
District of Columbia, with one species. During the last three years 
descriptions of three additional species have been published, bring- 
ing the known flora in the Maryland area up to 44 species. The 
present contribution, which is to be regarded as preliminary in 
character, brings the total Magothy flora of Maryland up to 71 
species and makes known several new localities. Many additional 
localities, as yet unexploited, will largely increase these figures. 
The present localities are Grove Point on the eastern shore of 
Chesapeake Bay in Cecil County at the extreme top of the forma- 
tion; Round Bay and Little Round Bay on the Severn River in 
Anne Arundel County, also near the top of the formation ; Bright- 
seat in Prince George’s County ; and Good Hope Hill and Penn- 
sylvania Avenue extended in the District of Columbia across the 
Anacostia River from Washington. 
Synonymy is entirely omitted.
