mirabilis x globosa / mirabilis x kuchingensis / globosa x kuchingensis
all have mirabilis kind of pitcher.....
So, the only way we can tell if the plant is a hybrid with xkuchingensis is to look for ampularia trait that is if any indumentum present.
But what about if the hybrid is mirabilis x globosa, the plant pitcher would be in between...no longer than mirabilis and no shorter than globosa. But then again the variation of the pitcher from a pure sp. is diverse. So we can't really tell the plant is a pure sp. of globosa or a hybrid with mirabilis.
