Variation in Lycoris squamigera

Hello Jim   Availability of the article made me want to print it out for 
further look-see.  Maybe I can learn something that also  accords with my 
belief that there is more than one type of clone of squamigera out there . 
I may try to get some of the different ones that I've seen locally.  But I 
tend to forget, don't feel up to it and the window of opportunity is brief.

That would account for some of the discrepancy. Two or three phenotypically 
similar hybrids from one or two parentages (each masquerading as squamigera 
would account for the differences without having to invoke the idea of 
dropped or lost  chromosomes at meiosis or fertilization ).
