Just thought I'd see if anybody here worked with any leaf-less/shoot-less orchid taxa? Campylocentrum, Dendrophylax, Harrisellia, Polyradicion, Chiloshista?

I know they are rare in cultivation and hard to come by, but I study them so I just thought I'd ask. Can you imagine a plant with out stomata that does photosynthesis? CAM none the less. Just mind blowing.
