60. Marreucia StrutrHropTeris (L.) Todaro. (Ono- 
clea Struthiopteris Hoffm.) With a range in North 
America from Newfoundland to Virginia and west to 
Iowa and British Columbia, the northern limit of this 
species swings south to the Lake Superior region. It 
was found by us at Nipigon and at the bottom of a 
deep narrow gorge at Orient Bay, south end of Lake 
Nipigon, but there appear to be no other reports of 
its occurrence along the north shore of Lake Superiur 
or inland from there, excepting in the warmer valley 
northwest of Fort William, where Macoun reports it 
“five miles up the Kaministiquia River,” and where we 
collected it along Oliver Creek, three miles southeast 
of Stanley, and at Kakabeka Falls. It will be inter- 
esting to know if it occurs to the north of the north- 
eastern shore of Lake Superior.
