Do you have any stapeliads?

No. We looked them up in our reference book, and we definitely don't have
any.

Stapelia spp in particular are called
'carrion flower' because of the putrid and/or sewage-like smell of
their flowers, which are fly-pollinated.

None of the cacti or succulents are flowering right now, anyway. Thanks for
trying, though. Any other ideas?

TIA
