As an undergraduate, I did some research into the heritability of the
ability to detect the bitter taste of various substances. For
several types of these substances, there are demonstrably "tasters"
and "non-tasters" and that the ability to taste them is genetically

While I know of no scientific studies in this area currently under
discussion (i.e. the compounds in aroid floral odors), it would not
be unreasonable that similar mechanisms might exist.

lord malodorus,

i am not saying that Amorph. don't stink when they flower. i don't doubt the chemical composition of the compounds in the inflorescences. all i'm saying is i have not detected any strong smells in the two you sent me that bloomed (sumawongii and longituberosus). maybe i'm just not home when they stink to high heaven, but in the morning and in the evening when i am, i couldn't detect anything. i think bernhard also couldn't smell a thing. i was expecting my apt. to smell like a rat had died but so far it hasn't happened (thank goodness).

it's interesting because Stapeliads also have a reputation for being "carrion flowers" and i could detect very clearly the stench from Edithcolea grandis when it bloomed, but it wasn't detectable from a distance. with Stapelia angolensis, i had to stick my nose up the flowers to get a whiff of that pestilence. it just sounds to me that the bad odors of some flowers have been greatly exaggerated. of course, with an inflorescence as big as titanum, i'd think the odors are much stronger.

I agree. But we can at least establish that the scent is there and the nose
is the problem (or the genes that control the nose). The odour studies have
been published in two papers, one in Phytochemistry and one in the
proceedings of a symposium.
