*Agropyron molle ( Scribn. & Smith). Agropyron sficatum mollc 

 S. & S., Bull. U. S. Dept. x\gric. Div. Agiost. 4: 33. 

 Empty and flowering glumes and rachis villous-pubescent. I regard 

 this as a good species intermediate between the preceding and the fol- 

 lowing. Rather rare.

*Agropyron dasystachyum subvillosum Scribner & Smith, Bull. U. 



S. Dept. Agric. Div. Agrost. 4: 33. 



It differs from ^1. repens, etc., in the flowering glumes, which are 

 densely pubescent. The variety differs from the typical A. dasy- 

 stachyum of the East in being more slender, a shorter and more 

 crowded spike, and shorter spikelets. Meadow^s to an altitude of 

 2000 m.

* Agropyron pseudorepens Scribn. & Smith, Bull. U. S. Dept. Agric. 



Div. Agrost. 4 : 34. 



Differs from A. repens by the empty glumes, which are about as 

 long as the spikelet, the harsher leaves and narrower spikelets. Com- 

 mon in meadows throughout the prairie region and ascending to an 

 altitude of 2000 m.
