Obs. Doctor Muhlenberg supjiosed that this might be a variety of S. viridis,-- 

 to which it is r C r!uinly allied ; but it seems to be sufficiently distinct. Some years 

 ago, it ire* introduced here as an object of culture, and excited much interest for 

 a time, among the Farmers. It was soon found, however, not to be as valuable as 

 the usual summer crop, of ichi<k it occupie I the place ; and the cultivation of it is 

 now pretty much abandoned. The seed is sown in the early jwrt of May.
