thicket along margin of cold rivulet, Porphyry Island, L. Superior, July 23, 
1913 {3692) and July 26, 1913 (3796)] Maloney Harbor, Black Bay Peninsula, 
Lake Superior, Aug. 17, 1913 ( 4871 ); Boggy woods east side Loon Lake, Sept. 9, 
1 9 1 3 ( 5 2 68 )\ In boggy woods along trail west of Sioux Lookout, Sept. 7, 1914 
( 7538 ). 
From arctic regions ranging along the North American coasts as far south 
as New Jersey and California, the species has been found inland in central Penn- 
sylvania, Ohio, Michigan, Wisconsin, and Minnesota, and our records show it 
rather general along the northwest shore of Lake Superior and to the northwest 
of there. However, we did not get it from Nipigon nor east of there along the 
North Shore, nor from the Lake Nipigon district. It occurs closely associated 
with the black spruce in muskegs and with alders fringing cold rivulets. 
5. Sphagnum teres (Schimp.) Angstr. (S. squarrosulum Lesq.). 
Mixed with other sphagnums in boggy margin of small lake between Orient 
Bay and Virgin Falls, south end Lake Nipigon, July 19, 1914 ( 6540 ). Macoun 
reports it along the Nipigon River (see footnote, p. 72.) Ranging south along 
the coasts to New Jersey and California, this species has been found inland in 
Pennsylvania, New York, Michigan, and Colorado, so that the Lake Nipigon 
station marks a still farther extension of range northwards in the interior of 
the continent. 
6. Sphagnum recurvum Beauv. (S. amblyphyllum Warnst.). 
Marginal bog of Six-mile Lake, Thunder Cape, Aug. 5, 1912 (1829) O. E. 
& G. K. Jennings & R. H. Daily; Ft. William Mission bog, Sept. 5, 1913 (5204); 
Boggy margin of little lake between Orient Bay and Virgin Falls, south end 
Lake Nipigon, July 19, 1914 (6538 & 6342 ); Along wet woods trail west of Sioux 
Lookout, Sept. 7, 1914 (7527); Bog at western edge of Graham, Sept. 7, 1914 
( 7578 ). 
According to North American Flora , this species ranges from “Labrador 
southwards to Florida and Louisiana; Colorado; Washington to Alaska; also 
in South America, Europe, and Asia, and reported from Africa.” No mention 
is made of any stations in the Great Lakes region, although it occurs commonly 
in northwestern Pennsylvania. Our collections would indicate a considerable 
mid-continental range for it, especially northwards. 
6 a. Sphagnum recurvum var. tenue Klingr. (S. parrifolium Warnst.). 
Boggy margin of lake near Ft. William Mission, June 19, 1912 (179 & 184 ) 
O. E. Jennings & R. Id. Daily; Spruce muskeg west of Heron Bay R. R. station, 
July 20, 1912 (1356) O. E. Jennings & R. H. Daily; In small open bog with 
Sarracenia, Iris, Chamaedaphne, etc., Orient siding, south end Lake Nipigon, 
July 2, 1914 (6161, 6180, 6181 ); Open bog at western edge of Graham, Sept. 7, 
1914 (7585). 
In North America this species ranges from Greenland to Pennsylvania, 
and from Washington to Alaska, occurring inland in central Pennsylvania, 
Michigan, Minnesota, Nebraska, Montana, and Idaho. Our collections show 
it to have a rather general distribution in northwestern Ontario also. It usually 
occurs in rather open bogs with Sarracenia, Iris, Cassandra, etc.
