 reddish purple colour. Stamens inclosed. Style prolonged.

This is a doubtful native plant, frequently cultivated in gardens, on 

 account of its extremely fragrant scent, which resembles " Bergamot 

 Orange, or the herbage of Monarda didyma." — Smith. It is nearly 

 allied to the following species, but its entire want of hairiness is 

 thought a sufiicient distinction. We only know it as a cultivated 

 plant, and it is probable in the stations above quoted it has escaped 

 from gardens.
