Rocky Mountain Calochortus

>On a recent trip to Colorado and the Beartooth and Bighorn ranges in 
Wyoming, we saw Calochortus in several places. I'm having trouble 
deciding whether these were Calochortus gunnisonii or Calochortus 
nuttallii, or one species in one site and the other elsewhere. Both 
species are reported to occur where we were, and both are quite 
variable. Can anyone advise me about distinguishing characteristics? 
Check this out.…
The band of maroon is apparently diagnostic for C. nuttallii.
