BERRY: MEsOzOIC FLORA OF ATLANTIC COASTAL PLAIN 403 
Asplenium cecilensis sp. nov. 
tending nearly from the midrib to the margin and obscuring the 
lateral veins, there being apparently a sorus to each forked lateral. 
(PLATE 18, FIG. 4, 5.) 
This species greatly resembles various forms from the Upper 
Cretaceous of Greenland, which Professor Heer referred to the 
genus Pteris, the resemblance to Pteris Albertsii Heer being par- 
ticularly marked. The latter is usually referred to the genus 
Cladophlebis, and this genus contains a number of forms that are 
comparable with Asplenium cecilensis. The fertile pinnules of the 
latter, imperfect as is their preservation, are clearly unlike those 
known in Cladophlebis and are clearly of a type allying this form 
with the Asplenieae. 
OccuRRENCE: Grove Point, Cecil County, Md. 
PopOZAMITES KNOWLTONI Berry 
Podozamites Knowltoni Berry, Bull. Torrey Club 36: 247. 1909. 
This well-known older Mesozoic species is common in the Upper 
Cretaceous of the coastal plain from New Jersey to South Carolina 
and also occurs in the Dakota sandstone of the West. It is 
present in recent collections from the Magothy formation in the 
vicinity of Round Bay on the Severn River in Anne Arundel
