The flowers make their appearance around August 1 1 , and 

 may be found as late as October 14. The heads are smaller than 

 in A. macro •phyllas, and are surrounded by 12 or more light blue 

 rays. In this species the upper portion of the light yellow discal 

 floret is more cylindrical than in the preceding species, being of 

 nearly equal width (1 mm.) throughout, and presenting a length 

 of \Ya mm. The lobes of the corolla are erect, or even slightly in- 

 clined towards the middle. A change in color to reddish-brown 

 takes place in the older floret. In this species the branches of the 

 style do not effect a crossing. 81 visitors were taken as follows :
