MARYLAND GEOLOGICAL SURVEY 901 



This species is based on a single remarkably well-preserved specimen 

 washed out of the sandy carbonaceous clays of the Magothy formation. 

 Its botanical relationship is uncertain since a variety of existing genera 

 have comparable fruits. Among these might be mentioned various genera 

 of the Euphorbiacece, Sterculiacece, Malvaceae, etc. Somewhat similar 

 Eocene fruits have been described by the writer as species of Sterculio- 

 carpus, and by Viguier as species of Sezanella, both genera being referred 

 to the family Sterculiacecs. 



Occurrence. MAGOTHY FORMATION. Deep Cut, Chesapeake and Dela- 

 ware Canal, Delaware. 



Collection. Johns Hopkins University.
