Contributions to the Mesozoic flora of the Atlantic coastal plain— I 



Edward Wilber Berry 



(with PLAThs 7-9) 



While the present paper by no means exhausts the floral 

 wealth of the Magothy formation, particularly within the state of 

 Maryland, it is deemed advisable to publish it at this time in order 

 to illustrate the remarkable floral unity of the formation, from 

 which practically no plant-remains have hitherto been described 

 outside the state of New Jersey. Such publication is especially 

 necessary for the reason that while the name Magothy was pro- 

 posed for these beds some years ago by Darton * it was not recog- 

 nized by other geologists until republished by \V. B. Clark in 

 1904^ its components having been previously referred to the un- 

 derlying Raritan formation or to the overlying Matawan formation. 



The plants are enumerated in their botanical order and include 

 forms from the following localities : Cliffwood bluff on Raritan 

 bay, New Jersey ; the pits of the Cliffwood Brick Company near 

 the head of Whale creek, New Jersey ; near Morgan on Cheese- 

 quake creek, New Jersey; Kinkora on the Delaware river, below 

 Trenton, New Jersey; the " Deep Cut" of the Chesapeake & Dela- 

 ware canal just east of the Maryland line in Delaware ; and Grove 

 Point on the eastern shore of Chesapeake bay in Cecil county, 

 Maryland. One or two species are included from the outcrop of 

 the same formation on Good Hope Hill just across the Anacostia 



river at Washington, D. C. 



The synonymy is omitted from all of the well-known but much- 

 named species, and forms previously reported are not included in 

 this contribution unless their range is extended.
