No. 577, p. 13. of Clayton, appears to belong to this species ; his pre- 

 ceding observations in italics certainly do. Notwithstanding this is the 

 most common speciesof Spartina, and from its situation not likely to be 

 overlooked, yet Michaux appears to have confounded it with hi^ 

 T. polystachya, a very distinct species ; and except by Walter, it 

 seems to have been united by our older botanists with very different 

 plants. 



This plant is greedily eaten by horses and cattle. It is remarkable 

 for a strong, rancid' and peculiar smell, aftecting the breath, the it)hk, 

 butter, and even the flesh of tlie cattle that feed upon it. It aftord* 

 however good pasturage for out-door stock, and is becoming valuaoie 

 •and valued as a manure.
