Nepenthes gracilis (/nɪˈpɛnθiːz ˈɡræsɪlɪs/; from Latin: gracilis "slender"), or the Slender Pitcher-Plant, is a common lowland pitcher plant that is widespread in the Sunda region. It has been recorded from Borneo, Cambodia, Peninsular Malaysia, Singapore, Sulawesi, Sumatra, and Thailand. The species has a wide altitudinal distribution of 0 to 1100 m (and perhaps even 1700 m) above sea level, although most populations are found below 100 m and plants are rare above 100
