*Some answers from Ian Young  to points  made....

"Gordon Hogenson (/Tue, 05 Jan 2016 18:10:20 PST/):

  In general, I have heard that Erythronium cross easily, although I 
don't know if this applies only to closely related species.
  I don't know what species will cross with which other species, or if 
all of them will potentially cross-pollinate.
  Did Ian hand-pollinate the montanum strains, or otherwise isolate them?

Ian:  I  hand pollinates these, Gorden and take  what measures possible 
to  protect them.
Some species are  promiscuous -  californicum, revolutum, oregonum, 
hendersonii for instance.
Some species  will cross in the wild it seems - while many are not 
amenable to hybridise - I  have made several attempts in such hybrids 
and failed.
The phylogenetic trees gives a hint as to which species might cross with 
their  closely related species.

"Jane McGary (/Tue, 05 Jan 2016 18:41:08 PST/)

Some people interested in Erythronium think that the narrow endemic
Erythronium elegans arose as a hybrid of E. montanum and E. oreganum. I
don't know whether this view is still widely held."

Ian : I think ( as does Brian Mathew) that  the  speculation is that  
elegans  is a hybrid of  montanum and revolutum .... an ancient stable 
  E. elegans  turns pink at a very early stage of growth which suggests 
there is  revolutum blood in it.  All speculation, of course.

Hope this helps,

  M. Young
