A COLLECTION OF SPHAGNUM FROM THE DOUGLAS LAKE REGION, 

 CHEBOYGAN COUNTY, MICHIGAN. 



W. E. PRAEGER. 



The following Sphagna were collectecl during the summer of 1918 at 

 Douglas Lake, Cheboygan County, Michigan, at the request of Dr. Geo. B. 

 Nichols, advisor to the Red Cross on Sphagnum for surgical dressings. The 

 specimens were finally determined by Dr. Albert Le Roy Andrews. 



The chief purpose of the collection ceased with the armistice. Only one 

 of my samples (number 24, Sphagnum magellanicnm) was first grade dressing 

 material ; this was from one of the small bogs and not in great quantity. 

 One other (number 15, S. palustre) was fair but also existed in small quanti- 

 ties. Two others (numbers 9 and 10. both S. magcllanicum) were poor but 

 might be used ; the rest were worthless. The collection however will be a help 

 to those who in future may survey the Bryophytes of the Douglas Lake Region. 

 and in this hope I record the list of species with localities. Samples of all 

 numbers have been deposited in the Cryptogamic Herbarium of the University 

 of Michigan.
