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.

This is something I hope to do as well, but I'm worried about the issue of cross-pollination with other Erythronium? 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? > Gordon >
