Natural History Publications (Borneo), Kota Kinabalu.〕 is a common lowland pitcher plant that is widespread in the Sunda region. It has been recorded from Borneo, Peninsular Malaysia, Singapore, Sulawesi, Sumatra, and Thailand.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes.

Prague.〕〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Sumatra and Java''. Redfern Natural History Productions, Poole.〕 The species has a wide altitudinal distribution of 0 to 1100 m〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Peninsular Malaysia and Indochina''. Redfern Natural History Productions, Poole.〕 (and perhaps even 1700 m〔) above sea level, although most populations are found below 100 m and plants are rare above 1000 m.〔Adam, J.H., C.C. Wilcock & M.D. Swaine 1992. ''Journal of Tropical Forest Science'' 5(1): 13–25.〕 Despite being a widespread plant, natural hybrids between ''N. gracilis'' and other species are quite rare. ''Nepenthes gracilis'' was formally described by Pieter Willem Korthals in his 1839 monograph, "Over het geslacht ''Nepenthes''".〔 ''Nepenthes abgracilis'' from the Philippines is named for its superficial similarity to this species.〔Cheek, M. & M. Jebb 2013. The ''Nepenthes micramphora'' (Nepenthaceae) group, with two new species from Mindanao, Philippines. ''Phytotaxa'' 151(1): 25–34. 〕 ==Carnivory== The small, elongated pitchers of ''N. gracilis'' appear relatively unremarkable and have a very thin peristome. Nevertheless, the species is unusual (and possibly unique) in that the underside of the pitcher lid bears an uneven layer of wax crystals. This layer is not as thick as, and structurally distinct from, that found in the waxy zone of the pitcher interior, and insects can easily adhere to it in dry conditions. During downpours, however, it functions as part of a trapping mechanism, whereby the impact of raindrops striking the lid causes insects to lose their footing and fall into the pitcher cup below.〔Bauer, U., B. Di Giusto, J. Skepper, T.U. Grafe & W. Federle 2012. With a flick of the lid: a novel trapping mechanism in ''Nepenthes gracilis'' pitcher plants.
