68 THE RARITAN FLORA. 



Like most of the Raritan fern-remains, those representing the 

 present species are fragmentary and inconclusive, resembhng, as 

 far as it is possible to judge, Heer's type material which came 

 from the Patoot beds of Greenland. As the latter is supposed to 

 be of Senonian age, it is possible that the New Jersey forms 

 belong to a different species of this genus, but of this it is im- 

 possible to form a satisfactory conclusion. It is to be hoped that 

 additional and better material will some day be collected which 

 will definitely settle the question.
