Sorry about the punny alliteration - couldn't help myself.
Anyway, I thought that I'd link two of my favourite stapeliad sites, for those of that inclination. A warning though: one might find them frustrating because one could well want to track down specimens for one' self (as I do!), and it's not easy to find the diversity in Australia.
Gerald Barad's Stapeliads: orchids of the succulent world.
Martin Heigan's Stapeliads "Hidden Treasures of the Desert"
I'll probably add more as I continue to torture myself, but please feel free to link any that might be of interesat to others.
