No idea. Just...weird.
Not even sure if it's a flower. Saw it in a Texas nursery 10 years ago, thought it was an oddity and snapped a shot or two with an Olympus E-P1 with 17mm lens.
Any ideas?
They should be of Nepenthes species, a kind of carnivorous plant. Each "pot" contains digestive fluid of sweet flavor which attracts insects. The insects fall into the pot and, alas, are digested in the fluid.
I'm not sure which part of the plant the "pot" would belong to, but the species is very well reserved to this thread!
