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 ).

Did you mean that L. straminea was a parent of L. squamigera or did you
mean L. longituba?
Dear Tony,
The lit says L. straminea. Seems odd, but see Kurita et all
paper, Synopsis of the Genus Lycoris, in SIDA 1994.
But according to Identification and Classification of the
Genus Lycoris Using. Molecular Markers.
straminea is 2N = 19, sprengeri is 2n = 22, longituba
is 2n = 16 and squamigera is 2n (3n) = 27
The only way you can get 2/3 n= 27 is to combine the 2n of
sprengeri and n or longituba to get 27 chromosomes.
To me it seems like squamigera looks like a combo of
longituba and sprengeri, but the experimental crossing of straminea x
sprengeri produced the look alike. Odd
If the Roh et all chromosome info is correct, the parentage
of Squamigera could ONLY be Sprengeri x longituba.
All the karyotype info in Roh is fairly confusing.
