State. This prediction has been fulfilled by the discovery 

 of this fern in the town of Hartland. in September last, 

 by Miss Nancy Darling. To find this northern form here 

 seems somewhat surprising in view of the fact that the 

 nearest stations previously known were in Gaspe, Quebec 

 and Xova Scotia ; but it is evident that northern condi- 

 tions are present in some degree, for from the same town, 

 which has no great elevation, are reported Polystichum 

 Braunii, JJ^oodsia glabella and possibly W. alpina, 

 though the latter has not been confirmed by specimens 

 submitted to the writer. Specimens of the Dryopteris 

 Filix-tnas have been deposited by Miss Darling in the 

 herbaria of the University of Vermont and of Columbia 

 University.
