162 GEOLOGICAL SURVEY OF CANADA. 



C. arctata x flexilis, Eailey. 



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

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

 0. arctata and G. fleodlis. Where I gathered the speciraens at Kaka- 

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

 i/ake Superior, both of these species were found growing in profusion. 

 Specimens of 0. j^eajiKs, sent from Tobique Lake, N.B., by Wetmore, 

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

 all it is a lax form of G. 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 Eapids, east of Brandon, and in the Grand Valley, leading
