 in America. H.]

 the east, to Kotzebue's Sound on the west; and at the Columbia. J. Whale Fish Islands. Captain Sir E. 

 Parry y and Captain James Ross. — [This extensively distributed plant is, as may therefore be expected, very 

 variable : the two opposite extremes may be considered the var. J. above noticed, whose leaves are scarcely 

 two inches long, and the state found at the Columbia, whose leaves are a foot or more in length, and whose 

 roots are eaten by the Cherokee Indians. H.]
