I really wonder about that, though.  Isn't it just as likely that in 
ancient times there was one basic Erythronium, then as climate and 
geographic changes isolated populations they evolved into different 
species.  Just because there is pink in E. elegans (and it grows quite a 
distance from any E. revolutum that I know, and a VERY long way from E. 
montanum), doesn't mean it has E. revolutum in its ancestry.  All of 
these: E. revolutum, oregonum, californicum and elegans are going to be 
very very close genetically, so just the expression or repression of a 
few genes could be responsible for the color variation.
