What I found so far is that Bulb. annandelei is stinky too. I don't know if you want me to be more specific with what the scent supposedly resembled or not. The flowers look cool, though.
Also, I read that Bulb. carunculatum resembles the smell of 'hard apple cider' but only if you put your nose close. Again, cool flowers.
I can't find anything regarding a scent for Bulb. harbrotianum, though. Maybe no news is good news!
