Nepenthes campanulata   Kurata

This small, curious species is found on the island of Borneo (Kalimantan).  It is only known from two areas and the southern location went extinct in the 1970's.  All of the plants in cultivation are from Gunung Mulu National Park in Sarawak, Malaysia.  In the photograph below, the three rosettes are all one plant branching from underground.

This species appears to live exclusively on limestone cliff faces.  It has several adaptations for living on cliffs which making it rather different form most other species of Nepenthes.  N. campanulata has very short internodes and so doesn't actually vine, reaching only about 50 cm long.  It has not been observed to make prehensile tendrils.
