Very interesting.  From our experience, it's pretty easy to venture a 
good guess about the parents of most lycoris since the genetics of each 
parent show in the offspring.  From a plant breeders perspective, there 
is no way that L. straminea is involved in L. squamigera.  That being 
said, I'd bet we are looking at some misidentified plants in the 
literature. We've all seen how confusing this was in the crinum world 
where many of the reported parents in the old literature were 
incorrectly identified.
