This species is most likely to be confused with L. montana 
and is distinguished from it chiefly by the normally globose 
pods. The ranges of the two nearly meet in New Mexico but 
farther north the Continental Divide separates them. The 
pods in L. montana are densely stellate, while the stellae on 
those of L. rectipes are rarely contiguous.
