 Sitka. Ea.stward it is found in the northern border States and in tlie mountains southward, and

 Louisiana, has not thus far been detected within the State. It has a nuieh denser ami nariower 

 lianiele, longer sj)ikelets (sonietinu'S 3 lines), and is often tinged wilh purple. The type ami 

 vaiiety have a rather [)leasant scent, but neither appears to be sought after by cattle.
