Collected in low ground near Cheyenne, Wyoming. July, 1889, 

 by J. E. Bodin for whom the species is named and to whom I 

 am indebted for a good series of the Astragali collected by 

 himself in Kansas, Nebraska, Colorado and Wyoming. Also 

 collected near Laramie, July 1889, by Dr. Edw. L. Greene. 



The species is nearest to Astragalus tenellus Pursh, but the 

 habit is more nearly that of Astragalus flexuosus DouGL.
