Ohs. This is a remarkably aromatic plant, of a sweet, anisate odor; and, while young:, thickly covered with, 

 soft canescent liairs. Children are fond of collecting the roots to chew, and sometimes commit serious

 followed Mr. Nuttall, in separating this from the preceding; but, in my opinion, they are almost too cloaeiy 

 allied to constitute distinct genera.
