318 Correlation of the Upper Cretaceous Formations 



The ten species common to the Baritan of Maryland and New Jersey 

 are: Asplenium dicksonicmum, Cinnamomum newberryi, Czekanoivskia 

 capillaris, Diospyros primceva, Ficus ovatifolia, Fontainca grandifolia, 

 Podozamites lanceolaius, Podozamites marginatus, Sdlix lesquereuxii, 

 and Sassafras acutilobum. 



The four species of the Maryland Baritan that occur in the overlying 

 Magothy of this State are Cinnamomum newberryi, Diospyros primmva, 

 Salix lesquereuxii, and Sassafras acutilobum. 



The total Baritan flora of the North Atlantic Coastal Plain when com- 

 pared with that of the complete Magothy flora shows that 139 forms have 

 not been found in the Magothy. 



The Magothy flora of Maryland consists of 100 species, of which 6 

 are ferns; 19 are gymnosperms; 4 are monocotyledons, including the 

 remains of a fan palm ; and 69 are dicotyledons, well distributed among 

 the natural orders. Fifty-one species, including many distinctive forms, 

 are common to the Magothy of the area from New Jersey to Marthas 

 Vineyard. Forty-two species occur in the Baritan flora of either Mary- 

 land or New Jersey, this large number being clue primarily to the pre- 

 nuntial character of the flora of the uppermost Baritan of South Amboy, 

 New Jersey. When the Magothy flora of the north Atlantic Coastal 

 Plain is considered as a whole, its individuality is strongly emphasized. 

 A large number of peculiar species are present and many genera appear 

 in the geologic record for the first time. Its distinctness from the Baritan 

 flora is indicated by the fact that 202 Magothy species do not occur in 

 the Baritan. 



The most characteristic forms common to New Jersey and the Islands 

 are : Aralia ravniana, Carex clarkii, Dammara cliff woo densis, Diospyros 

 rotundifolia, Ficus crassipes. Ficus krausiana, Liriodendropsis constricta, 

 Magnolia capellini, Magnolia obtusata, Magnolia, tenuifolia, Moriconia 

 americana, Populus stygia, and Quercus morrisoniana. 



A correlation of the Upper Cretaceous faunas of Maryland in this dis- 

 trict must be chiefly made with the better-known faunas of New Jersey.
