A. repens, Beauv. (T. repens, L.) Couch-, Quitch-, Quick-, or Witch- 

 Grass. 

 Frequent, or common, throughout the state, but rarely so plentiful as to be trouble- 

 some. (Specimens which must be referred to this species, as decided by Mr. Sereno 

 Watson, were found at Minneapolis on the embankment of the railroad about an eighth 

 of a mile northwest from the University and close west of Tuttle's brook, having a very 

 narrow and long npike of many spikelets, awnless, as long or half as long as the joints 

 of the rhachis, 3-flowered, with a rudiment of a fourth flower, often the lowest or the 

 middle flower not ripening its grain, and having in some instances no running root- 

 stocks. The typical T. repens occurs near by, and also forms which seem to be inter- 

 mediate in respect to both the character of the spikes and the presence of rootstocks.
