MOSSES. 



•Considerable attention has been given the moss flora, though the knowl- 

 edge of the flora is not by any means complete. 



In 1898 Professor John M. Holzinger devoted a season to the mosses of 

 the Sperry Glacier region. In 1901 W. P. Harris devoted a season to the 

 mosses of the vicinity of Flathead Lake. This material was identified by 

 Carolyn M. Harris. In 1908 I also collected the more common mosses of 

 the Lake and adjacent mountains, though no attempt was made to make it 

 thorough, as my time was devoted to the higher plants chiefly. 



All my material was identified by. Mr. Holzinger, and the Harris material 

 was examined by Mrs. Britton. 



Fortunately Mr. Holzinger had prepared a manuscript of his Sperry Gla- 

 cier mosses which I have prevailed on him to permit me to print in this 

 report. It is so much more complete than the Harris or my list that it is 

 given as prepared. I have added to it the localities and few additional 

 species found on the Harris list and my own, always adding the name of 

 Harris or Jones to all species collected by us, so that all other localities 

 and notes may be known as those of Mr. Holzinger. 



"In July, 1898, the writer, J. -M. Holzinger, in company with Mr. James 

 Blake, made a vacation trip into Northwest Montana, during which they 

 collected the Mosses and Hepatics herewith published. The region visited 

 is reached by the Great Northern railway, which we left at Belton, thirty 

 miles east of Kalispell, striking some twenty miles north, to the north end 

 of Lake McDonald. There we pitched our permanent camp. The country 

 is very rugged and secluded. It is especially interesting because of the 

 several glaciers which nestle among the precipitous mountain peaks. "We 

 visited only one of these, Sperry Glacier. 



During our brief stay we made the following excursions: To Holzinger's 

 Basin, eight miles east of camp, July 16 to 19; to McCrimmin Falls, on the 

 McDonald Creek, near the upper end of the lake, July 20; to Mt. Trilby, four 

 miles northwest of camp, July 21; to Sperry Glacier, twelve miles northeast 

 of camp by way of Holzinger's Basin and the Rim, July 24 to 26; and to 

 Avalanche Basin, below Sperry Glacier, 10 miles northeast of camp. A more 

 detailed account of this interesting region may be found in the September 

 number, 1900, of the Bulletin of the American Bureau of Geography. 



The determination of the collection has been delayed for various reasons. 

 Dr. R. H. True has determined most of the Dicrana; Dr. H. J. Grout, the 

 Eurhynchia and Brachythecia, and several other species; Dr. G. N. Best, the 

 Prendoleskear, etc.; Dr. C. Warnstork the Sphagna; Mr. Renauld, the Har- 

 pidia; Mrs. Britton has determined the Orthotrica, and has critically exam-
