8o THE RARITAN FLORA. 



These fruits always occur detached and are present in con- 

 siderable abundance at Woodbridge, but have not been detected 

 from other localities in the Raritan. Similar remains are re- 

 corded from the Tuscaloosa formation of Alabama, and they are 

 also present in the Bladen formation of North Carolina. As 

 their name indicates they are assumed to represent the fruit of 

 some contemporaneous species of cycad.
