I did not note the relative abundance of this species. Gathering together my 
various ecological notes and other data it appears quite certain, however, that 
S. magellanicum occurs in considerable quantity throughout most of the region 
but it is practically always closely associated with a number of other species 
and practically always occurs with Myrica or Chamaedaphne,' or in black spruce 
muskegs, in each case likely to be mixed with twigs and other foreign matter. 
Generally speaking, this would not likely be a good region for extensive gather- 
ings of the moss for surgical purposes, but I have no doubt that careful search 
among the bogs of the North Shore district of Lake Superior would reveal here 
and there supplies of good quality.

Near Rossport, July 14, 1912 {1053b) O. E. Jennings & R. H. Daily. Bogs

Florida and Alabama; [also central Pennsylvania — O. E. J .] ; Illinois; Vancouver 
Island to Alaska; also in Europe and Asia.” The additional stations extend 
the mid-continental range of the species considerably to the north.

In the regions visited, S. Wulfianum seems to be almost always prominently 
associated with the black spruce, often forming mounds of considerable size. 
North of the head of Ombabika Bay, in the extensive spruce muskeg covering 
the gently ascending slope, the mounds were often three or four feet in diameter 
and as much as a foot high. In North America the' reported range of the species 
is from Greenland and eastern Canada to Connecticut; New York; Minnesota; 
and Vancouver Island. It is also reported from Siberia and northern Europe, 
and its abundance in the Lake Superior and Lake Nipigon districts would indi- 
cate a considerable mid-continental range in America to the northwards.
