Variation in Lycoris squamigera

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.
