Occurring from Michigan, Illinois, and Iowa northward to the 

 plains of middle Canada; at Orono, Maine; in the Black Hills 

 of South Dakota ; and, on the authority of a label in the Canby 

 Herbarium, in Middle Park, Colorado. /. vaseyi differs from the 

 last, in addition to its important seed and perianth characters, 

 in its inflorescence usually exceeding the lowest involucral bract, 

 and the green, or, at maturity, stramineous capsule being little 

 or not at all contracted toward the apex.
