A species of very peculiar habit due chiefly to the den- 

 sely clustered heads on long naked peduncles, and to the sub- 

 -cylindrical involucres with their peculiarly imbricated scales. 

 In fact, it resembles somewhat a Baccharis, to which genus 

 it was referred by Grisebach. 



Prof. Urban, who was the first to realize the Vernonian 

 nature of the plant, described it in manuscript as a particular
