FILICALES. 73 



Description. — "O. spica fertili elongata, sporangiis distichis, 

 ovalibus granulatis, i^ mm. longis." Heer, 1883. 



This species described originally by Professor Heer from the 

 Patoot beds of Greenland and compared with the fertile frond 

 of Ophioglossum vulgahmi has been found in considerable num- 

 bers in the Raritan clays, although Professor Newberry failed 

 to indicate the exact localities. There can be no question of the 

 identity of the Greenland and the New Jersey material. The 

 reference to Ophioglossum is not so conclusive, and many 

 students will echo Newberry's supposition that these remains are 

 those of staminate cones of some species of conifer. Since no 

 new light can be shed on their systematic position, they are re- 

 tained where Heer and Newberry placed them. 



Occurrence. — Locality unknown.
