162 GEOLOGICAL SURVEY OF CANADA. 



C. arctata x flexilis, Bailey. 



C. Knieskernii, Dew. Sill. Journ. 2d. Ser. II., 247, (1846.) 

 I agree with Prof. Bailey in believing that this is a hybrid between 

 C. arctata and C. flexilis. Where I gathered the specimens at Kaka- 

 beka Falls, on the Kaministiqua, thirty miles from Fort William, 

 Lake Superior, both of these species were found growing in profusion. 

 Specimens of C. flexilis, sent from Tobique Lake, N.B., by Wetmore, 

 contained a fine clump of C. Knieskernii. It is just possible that after 

 all it is a lax form of C. flexilis, as it certainly approaches that species 

 very closely.

(2656.) C. Assiniboinensis, W. Boott, Bot. Gaz. IX., 91, (1884.) 



A very beautiful and distinct species well described by Boott. Peri 

 gynium few-ribbed towards the base, hairy, gradually contracted into 

 a very long slender beak, which is white and membranous at the tip ; 

 scale white, awl-shaped, the lower ones awned and longer than the 

 perigynium, the others about the same length. In thickets at the 

 Assiniboine Rapids, east of Brandon, and in the Grand Valley, leading 

 to Rapid City, 1879; on a dry limestone point at the "Narrows" of
