Introduction. ?., , 



The material represented in this bulletin was collected by Wilson P. 

 Harris, as will be noted later. The identifications were made by his 

 mother, Mrs. Isaac Harris. As a basis for subsequent work I deem it 

 advisable to record the results in permanent form, without attempting 

 descriptions or keys for identification. 



The localities marked with an * are from material collected by my- 

 self at different times, and identified by Prof. Bruce Fink. The notes 

 enclosed in brackets are my own. 



The illustrations were made at the University of Montana, due credit 

 being given therefor. By consulting Bulletins Nos. 3, 4, 5 and 6 of the 

 Biological Series many additional illustrations of the region may be seen, 

 showing the character of the country, soil, mountain summits, etc. 



The mosses were identified by Mrs. Elizabeth G. Britton, the well 

 known authority for this group. 



Duplicates of the collections made by Mr. Harris are in the posses- 

 sion of Mr. Harris and his mother, of the New York Botanical Garden at 

 Bronx Park, and at the University of Montana at Missoula, Mont.
