Comment:
Nepenthes reinwardtiana is a carnivous plant, native to Borneo. One of it's main characteristic features are the two "eye spots", just discernible in visible light at the rear face of the pitcher. The spots lack the scales of the waxy zone of the rest of the pitcher. Their function remains a mystery. The image below shows the spots much exaggerated in UV, together with the peristome (the ring around the top of the pitcher).

Very nice examples - kudos. I have documented similar appearance in UV of Sarracenia species, by the way. They were without the "eyes", though, but otherwise having lots of iridescent hairs and the shimmering ring around the opening into the flower..
