Zulth, in case we're talking about home-made hybrids, I can't guarantee my identifications. Globosa and mirabilis are the same a part from the pitchers, and a young very good looking mirabilis can look like a young very bad looking globosa. The hybrid x kuchingensis is mirabilis x ampullaria. Now, if some people - I don't see why
- are so brave to cross mirabilis x globosa or mirabilis x kuchingensis or globosa x kuchingensis, you see how the resulting seedlings - in their range of variation - can look like anything
The leaf base on a climbing stem and a very close look to the indumentum would help to see the presence of ampullaria.
