BOTANICAL GAZETTE 



Colorado, I saw but few insects visiting the flowers except the species 

 of bumblebee mentioned. Occasionally a fly or a bee would alight on 

 them, but was capable neither of obtaining nectar nor of dislodging the 

 pollinia. The bumblebees, however, on warm spring days, were actively 

 at work on them; there was no hesitation in their work; they knew where 

 the honey was stored and how to get it. I found pollinia and corpuscula 

 attached to the legs of all bumblebees I caught on Asclepias cryptoceras. —
