This plant we have seldom seen more than two feet high, the leaves are 
mostly in a rosette at base of the flowering stem with a few linear ones upwards, 
the flower heads are small and purple; it is apparently confined to the coast dis- 
tricts; we have not met with it at more than 500 feet above sea level, and it is 
usually found in moist places.
