I recently moved my _H. heterodoxa_ into my office and keep it in a terrarium.
There are two plants in the terrarium, one producing adult pitchers, one
juvenile pitcher. As soon as I moved it (from my greenhouse) the next two
pitchers have the characteristic "tuba" shape mentioned above. I think it
it is probably low light conditions that have caused this, so I'm moving it
back this weekend!
