I have to admit to not being confronted with too many clones of A. bulbifer
and it would be imaginable that there are "good" smelling ones. The chemical
composition of the plants we tested consists almost entirely of
dimethyltrisulphide (96%), 2% dimethyldisulphide and 1%
dimethyltetrasulphide. Now my experience is that species in which the
content of dimethyltetrasulphide is higher, a certain "sweetness" develops
but it is a very delicate balance with nauseaous. I also found that bad
smelling plants change their odour sometimes when the bloom ages and usually
also ends up "sweetish". My guess is that the amount of the tetrasulphide
relative to the other two sulphides determines this sweetness. There is
absolute variation in the tetrasulphide amount in certain species, so indeed
you may have clones in bulbifer with more sweetness. Having said all that, I
don't like the tetrasulphide sweetness at all. It is too close to nausea.

Well, I hope you learned you sulphides lesson here!!
