PTERIDOPHYTES OF NORTHWESTERN OnTARIO—II 77 
ported from Nova Scotia to Maryland and west to 
South Dakota and Nebraska, also Washington and 
Europe, this species was recorded by Macoun from 
islands in Lake Nipigon and from below the railway 
bridge at Nipigon, and he further notes that it is “in 
Canada, so far as known, limited to the westward by 
Lake Superior.” We collected it only in aspen woods 
on a sandy peninsula, on east side of Orient Bay, Lake 
Nipigon. 
29. BoTRYCHIUM TERNATUM var. RUTAEFOLIUM (A. 
Br.) D.C. Eaton. (B. Matricariae Spreng.; B. rutaceum 
Sw.) With a general range from Labrador and New- 
foundland and to New England and New York, also 
horthern Michigan and Eurasia. This is evidently the 
plant noted by Macoun from the north shore of Lake 
Superior at Red Rock, Nipigon River; at Fort William; 
and at the mouth of the Rainy River, Lake of the Woods. 
We found it in a low grassy pasture, Marie Louise Lake, 
Thunder Cape; in aspen woods on low sandy peninsula, 
Orient Bay, Lake Nipigon; and on shore of Pelican 
Lake and on west slope of Sioux Lookout Knob, Graham. 
See Hopkins, L. 8. (5a). As noted in our earlier papers 
this last record extends the known range considerably 
to the northwest. 
30. Borrycurum vireinranum L. This widely dis- 
tributed species is common in mesophytie woods, where 
Well drained. Macoun reports it from Red tock, 
Nipigon Bay; Thunder Bay; and up the Kaministiquia 
iver. Our records are: Along the north shore of 
Lake Superior at Heron Bay; Rossport; Nipigon; Magnet 
Point; Silver Islet Harbor; and Fort William; while 
inland it was collected at Longuelac; Jellicoe; Orient 
Bay; Loon Lake; and Pelican Lake, at Graham. 
30a. Borrycurum VIRGINIANUM Var. GRACILE (Pursh) 
D. ©, Eaton. In our collections once: In arbor-vitae 
bog one mile north of Marie Louise Lake, Thunder 
pe.
