Sure. It gets a little complicated, though. I pulled out Beaman's monograph and found this: few, thick stems=parryi. Many, slender stems=florifer. The two do overlap in northeastern Idaho and northwestern Wyoming and form hybrids. Townsendia parryi is generally apomictic (the populations that form hybrids are sexual). "The clearly marked features of this species are blurred only by hybridization with T. florifer." Bob Nold Denver, Colorado, USA
