Nepenthes lowii (Mulu)
Borneo, while not really the "hotspot" of Nepenthes distribution anymore, considering the amount of new discoveries from Sumatra still can be considered home of several of the most spectacular species, such as N. rajah, N. lowii or N. macrophylla.
Bornean Nepenthes species
Several of the most spectacular species, such as N. rajah or N. lowii grow in the highlands of Borneo, both in Malaysia and in Indonesia.
Nepenthes clipeata certainly is the most spectacular and desired species growing in lowland areas of Borneo. Nepenthes bicalcarata and N. ampullaria are other classics.
