but he does not specify any localities farther west in 
Ontario. It is likely that the northern limit of its 
range does not reach up around the north shore of 
Lake Superior. 
53. Finrx rracruis (L.) Underw. (Cystopteris fragilis 
Bernh.) This practically cosmopolitan species is rather 
common on cliffs and shaded rocks almost throughout 
the region visited. Our records for it are as follows: 
Heron Bay; Nipigon; Little Fluor Island; Paps Harbor, 
Black Bay Peninsula; Silver Islet, Thunder Cape; Mt. 
McKay, Fort William; Orient Bay and North Ombabika 
Peninsula, Lake Nipigon; slate cliff, Oliver Creek, 
Stanley; and slope of Sioux Lookout Knob, Graham. 
53a. FILrx FRAGILIS var. MAGNA-SORA Clute. Along 
sandstone talus slope, one and one-half miles west of 
Silver Islet, Thunder Cape, Aug. 4, 1912. 
54. Finrx montana (Lam.) Underw. (Cystopteris 
montana Bernh.) Ranging from Labrador and Quebec 
to Alaska and British Columbia, the northern limit 
of this species appears to swing down to Lake Superior, 
based on Macoun’s report of it at Current River, Port 
Arthur. 
55. Woopsia rLtvensis (L.) R. Br. Ranging from 
arctic regions south to the northern part of the United 
States, this species is fairly common on cliffs and talus 
slopes, often in company with Dryopteris fragrans. 
Macoun notes that it is “very abundant and luxuriant 
west and northwest of Lake Superior.” We collected 
it from the following stations: Rossport; Nipigon; 
Fluor Island; Paps Harbor, Black Bay Peninsula; 
Silver Islet, Thunder Cape; Mt. McKay, Fort William; 
Jellicoe; Virgin Falls, Orient Bay, and North Ombabika 
Peninsula, Lake Nipigon; Loon Lake; Oscar; and Sioux 
Lookout Knob, Graham.
