Heiberg Island: Hyperite Point, Schei (ex Simmons, Stray Contr.); Ellesmereland, 
comnion, Hårt, Feilden, Greely, Simmons. 
Geographic area (of the species). Greenland, arctic aud temperate North 
America, northeru Asia, northern Europé. 
KilKENTHAL, Cyp. Caric, p. 301, has placed the C. concolor of Rob. Brown 
as a variety of C. rigida, and Macoun, Cat., p. 141, has it as a synonym of C. 
ccBspitosa, but I think the Melville Island specimens must be referred to C, aquatilis 
var. stans. What the C. ccespitosa of Rae, Exp., p. 214, may be, is impossible to 
know, as no specimens exist.

Ostenpeld, Flora Aret., p. 81, as also Kukenthal, Cyp. Caric, p. 511, have 
adopted the name C. sparsiflora, (Wahlenb.) Steud., for this species, but as it is 
younger than that of Tausch as a species-name it is not in accord with the Vienna
