This puzzling species extends from Northern Europe, through 

 Greenland, and probably entirely across boreal North America, 

 into Eastern Asia. The plants described under C. filipendtila 

 by Drejer, have not heretofore been carefully collated with the 

 forms of C. cryptocarpa, I propose with confidence the following 

 disposition : 



Var. PUiMILA. 



C. filipendida, Drejer, van variegata, Drejer, 1. c. v. s. Hb. 



Havn.; Fl. Dan. t. 2371 (fig. not characteristic). 



Low (6 to 12 in. high) ; pistillate spikes commonly two, short 

 (^^ in. or less), ovate or short-oblong; scales broad and muti- 

 cous, but little longer than the much lighter colored perigynium. 



Norway, Fries; Iceland; near Victoria, B. C, Macowi, and 



Alaska, Kratise. 



Van H^MATOLEPIS. 



C, hi^matolepis, Drejer, I. c. 44, v. s. Hb. Havn. 



Drejer himself compared this plant with his C. filipendida^ 

 and his characters of separation, which the material now accum- 

 ulated shows to be only of varietal value, may still be quoted :
