Pitcher plant

Possibly the most extraordinary flower I have come across. Complex with multi layers of petals sepals and a chamber housing the male and female bits. The young lass bought the plant a couple of years ago , put it on the kitchen window sill and it's been well fed catching flies ever since. So well fed indeed , it's happy to flower.
The other funny wee story about this one is that for several days I was convinced one of the cats had peed in the corner. But no , it's the aroma of this flower.
