Hab. Arctic America ! and White Mountains, New Hamp- 

 shire, Dr. Boott. (fide Hook.) — 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. ccEspitosam proprius accedunt, et 

 eulmo laevi praecipue distingui possunt." The plant certainly 

 appears to be only a variety of C. ceespitosa.
