Hippeastrum ID query

"2n" just means just the whole set of chromosomes in the plant's cells.
For a diploid of 2n=22 species, the triploids have a total of 33
chromosomes per cell, so 2n=33 for those triploid sorts. It also suggests
why most triploids and why petiolatum with 2n=77 do not often set seeds.
