Neocaledonica is very closely related to spatulata (not spatHulata!), and are not part of the petiolaris complex. They appreciate warmth, high humidity and bright light but should not be treated like a petiolaris, temps. above 80F are not good. Incidentaly the plants can get quite large when grown well, forming a stem. This is not a beginners plant. I am still trying to find the right set of conditions. I have mine just moist, and probably will try a wetter substrate as I do not have good success with this species. Arie, the cutting you sent is doing better than the larger rooted specimens I received, and I believe this species dislikes transplant. Phill Mann grows his in highland Nepenthes conditions with good success.
