Hab. Arctic America ! and White Mountains, New Hamp- 
shire, Dr. Boott. (fide HooJc.) — Our specimens, collected at Bear 
Lake and Norway House by Dr. Richardson, pertain to the 
variety thus noticed by Brown on page 209 of the work above 
cited. — " Specimina proceriora, spicis femineis longioribus, axi 
squamarum pallido, ad C. cccspitosam proprius accedunt, et 
culmo Isvi prsecipue distingui possunt." The plant certainly 
appears to be only a variety of C. caspitosa. 
+ t Staminate spikes commonly two or more.
