 branching, round, smooth, white ; flowers bright yellow ; 2 to 3 feet 

 high ; this very handsome plant I found on the dry banks of the Columbia, 

 a few miles below the Falls ; it is by no means plentiful ; what it belongs 

 to I cannot say ; I regret that seeds of it cannot be procured for the 

 present.
