1, 2, 4, 7 to 17, I. 



Found on the Continent and in North America. 



Obs. — At once distinguished from all other round-leaved 

 species by its postical trigonous perianth and postical amentiform 

 androecia ; when barren, by its arcuate stems and abundant stout 

 flagella. From C. (0.) deniidata (Mart.), see notes under that 

 species. 



Var. alpina, MS. is a small neat form of a reddish-brown colour 

 with smaller cells, firm walls, with indistinctly thickened angles, 

 perigonial bracts ovate-rotund, with a third, antical, basal tooth, 

 found on the Scotch and Welsh mountains. I have not been 

 able to observe other characters to enable me to separate it from 

 the type.
