In Narcissus the basic number is n=7, except in the tazetta group where n can
be 10 or 11 but not 7, hence the frequent but not inevitable sterility when
one crosses the tazetta group to other Narcissus.
At least this is how I learned it 20-25 yrs ago, since then various oddball
species have been discovered and I am not sure if they fit in any differently
or not. Harold Koopowitz is the one to ask about that. And he has worked with
N. serotinus, whose basic number is, I think, n=5.
