A common and rather showy plant in the higher mountains. It receives its com- 
mon name from the fact that it is one of the first plants to spring up where forests have 
been swept by fire, persisting in the ‘‘burns” until they are reforested. Tnis habit 
of the plant results largely from the structure of its seeds, which are peculiarly adapted 
to dispersal by wind, being furnished with tufts of down.
