Stem branching at top; leaves alternate, linear; 

 spikes headed ; flowers beardless. Mich. abr. 



The purple, or rose coloured heads of this plant are very ob- 

 servable in moist ground, during the months of August and 

 September. Stem erect, angular, its branches exceeding the 

 main stem in height. Leaves alternate, smooth, linear-lanceo- 

 late. Flowers in terminal, cylindrical heads. As these heads 

 increase at their summit, the lower flowers fall ofF, leaving a 

 raggfid or squarrous peduncle, on which Linnaeus founded his 

 specific character.
