Heuchera hispida Piirsh. Eoiigh Heuchera. Alum-root. 
This plant is remarkable on account of the close relations 
existing between it and the bee Collet es wstivalis Patton. The 
latter is an oligotropic bee, collecting pollen from the flowers of 
some species of Heuchera only, and it has been observed by 
Patton (i) in Connecticut, on the flowers of H. anicricana, and 
by Robertson (2) in Southern Illinois, on H. hispida. Around 
Milwaukee it is a regular visitor of the latter species, and last 
year, on June 3, I also came across it at Eagle, Waukesha Co.,

road leading to Palmyra. In Illinois Roberson found the plant 
visited by this bee exclusively, but in our region bees of the
