Do you know of any good web pages that help with identifying Nepenthes by explaining what key features make a variety differ from other ones?
I have looked at photos in places like cpphotofinder.com . However, it is hard to know what features to focus on. For example, the main ones at this point in time I want to find the difference between are ventricosa x maxima and gothica. They both look similar in the photos online. However, I would expect gothica to be wider or fatter than ventricosa x maxima because sibuyanensis is wider or fatter than ventricosa.
