I only noticed today, but it could have been anytime during the last week or 2.
It is a small leaf cutting in a 9cm black square pot, with a non-carnivorous leaf still attached and one small pitcher, with more growth coming. It is actually very distinctive, as it is the "siamese Cephalotus" plant I posed a pic of a few weeks ago:

This plant was actually reserved, for Mike (sorry Mike, although I have a replacement I can offer you of similar size).
Not quite sure why anyone would steal one, as I would happily have sold it to whoever (apart from one or 2 banned members ). If anyone notices this plant in a collection, or is offered it for sale, please let me know with their details so I can contact the police. I will offer a reward of another 'Eden Black' plant for a successful outcome.
