 Burrage, John H. Redfield, Edward L. Rand, Edwin Faxon, 

 and Theodore G. White, determinations by Elizabeth G. Brit- 

 ton and Dr. Charles R. Barnes. 



In view of the great importance of following the arrangement 

 and nomenclature adopted in some standard work of ready ref- 

 erence, and in view also of the great disagreement on these very 

 matters of arrangement and nomenclature among the authorities, 

 it has seemed wise to follow Lesquereux and James's ** Mosses 

 of North America" in the preparation of this list. Synonyms, 

 however, have been given where they seemed of real value; 

 some necessary descriptions have been added; and a few cor- 

 rections made where they were of real, not merely of verbal 

 importance.
