Sue,

Yeah, dead rat - decaying flesh. It's not a fecal-based scent. Bulbophyllum
echinolabium has a fecal-based scent - makes people check their shoes
whenever they're within smell range but haven't seen the flower to know
where the scent originates. =)

Dead Rat? I thought this was the one that at NY Show always had
people thinking they stepped in Doggy doo. You mean it is worse than
that?
