This is the most uncommon (non-hybrid) Nepenthes species in Singapore, though it is still possible to find them in decent populations at the right localities. This include the forests in and around Kent Ridge Park, Bukit Timah Nature Reserve, Central Catchment Nature Reserve, Telok Blangah Park, as well as some offshore islands like Pulau Ubin and Sentosa (Chan et al., 1997).
While the the narrow backward flipped lids on the pitchers is a definite diagnostic, I have seen some which have broader lids that shields the pitcher opening instead. I suspect that these were young pitchers that were not fully developed judging from their small sizes. The upper pitchers of this plant are funnel-shaped, but are rarely seen. In any case, it seems that the lids do not shield the opening for a reason. It was showned by Pavlovič (2011) that this allows it to capture and digest plant debri, making the species not only a carnivorous, but also a herbivorous plant.
Together with Nepenthes rafflesiana, N. ampullaria was first discovered in Singapore by Dr William Jack in 1819, the doctor who accompanied Sir Thomas Stamford Raffles.
