Common on dry hills up to an altitude of 2500 m. Scribner and 

 Smith have taken up the name A. sficatiim for another species. I 

 have seen Lewis' specimen from which Fcstnca spicata Pursh was 

 described ; it is preserved in the Philadelphia Academy, and there is 

 no doubt that it is the same plant that has been known as A. divcr- 

 gcns. Pursh's original description calls for a long scabrous awn, 

 which shows that a mistake was made when the name A. spicatum 

 was applied to a member of the A. 7'epens group.
