A Revision of the North American Eurhynchia, 



By A. J. Grout. 



A careful study of the North American species ordinarily re- 

 ferred to the genus Eurliynchium, so far as represented in the 

 herbaria of Columbia University, the University of Wisconsin, 

 the National Museum, the collections of Prof. John Macoun, and 

 some private herbaria, together with selected specimens from the 

 herbarium of Harvard University, have convinced me that the re- 

 lationship of these species will be better represented by referring 

 them to more than one genus. 



I take pleasure in acknowledging my obligations to Prof. L. M. 



Underwood, Mr. 

 Macoun. and Dr
