Wide variations in shape, size and colour.
Conservation status: Least Concern
(IUCN Red List: assessed 2014, published 2018)
Nepenthes aristolochioides
Where found: Sumatra, Indonesia
Altitudinal distribution: 1800m to 2500m above sea level (highland/ultra highland).

Nepenthes bokorensis
Where found: Mt. Bokor, Cambodia
Altitudinal distribution: 800-1080 m above sea level (lowland).
Conservation status: Not listed
(IUCN Red List)
N. bokorensis does not appear to have been given a formal conversation status by the IUCN. However, François Mey suggested in 2009 that the species should be given the status of “potentially vulnerable” based on IUCN criteria.
Nepenthes campanulata
Where found:East Kalimantan (Indonesia)(Extinct)
Sarawak, Malaysia;
Palawan Islands, Philippines.
Altitudinal distribution: 100 – 400m above sea level (lowland)
Conservation status: Vulnerable
(IUCN Red List: assessed 2013, published 2014):
Mt. Ilas Bungaan was the type locality for the species (discovered in 1957) and the type subpopulation was destroyed as a result of forest fires in 1983; all other known subpopulations in the area were killed off in subsequent forest fires in late 1991 or early 1992. So for a time the species was thought to be Extinct until it was rediscovered in 1997 in Gunung Mulu National Park, more than 400 km away from the type locality. The discovery of the species in Palawan in 2013 greatly extended its known range.
Nepenthes clipeata
Where found: Mount Kelam, West Kalimantan, Indonesia.
