318 Correlation" or the Upper Cretaceous Formations 



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

 are: Asplenium dicksonianum, Cinnamomum newberryi, Czekanowskia 

 capillaris, Diospyros primceva, Ficus ovatifoUa, Fontain-ca grandifolia, 

 Podozamites lanceolatus, Podozamites marginatus, Salix lesquereuxii, 

 and Sassafras acuttiobum. 



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

 Magothy of this State are Cinnamomum newberryi, Diospyros primceva, 

 Salic lesquereuxii, and Sassafras acuttiobum. 



The total Raritan 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 Raritan flora of either Mary- 

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

 nuntial character of the flora of the uppermost Raritan 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 Raritan 

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

 the Raritan. 



The most characteristic forms common to New Jersey and the Islands 

 are: Aralia ravniana, Carex clarhii, Dammara cliff woodensis, Diospyros 

 rotundifolia, Ficus crassipes, Ficus Icrausiana, Liriodendropsis constricta, 

 Magnolia capellini, Magnolia obtusata, Magnolia tcnuifolia, Moriconia 

 americana, Populus stygia, and Quercus morrisoniana. 



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

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