I would like to say that there may be another reason why my N. tobaica has not pitchered for some time. I have seen 2 websites in which N. tobaica is described as a highlander (nepenthes university, michael catalani and Malesiana tropicals). Borneo exotics describe N. tobaica as a lowlander. Which is true??. If Rob Cantley's site is correct then, My N. tobaica is shocked by the ultrahighland conditions and that's why it does not pitcher. I will add another discussion topic to find out what is the general consensus regarding N. tobaica classification.
