Nepenthes rigidifolia /nɪˈpɛnθiːz ˌrɪdʒɪdɪˈfoʊliə/ is a critically endangered tropical pitcher plant endemic to Sumatra, where it grows at elevations of 1000–1600 m above sea level.[4]
The specific epithet rigidifolia is formed from the Latin words rigidus (rigid) and folia (leaves), and refers to the plant's stiff, coriaceous leaf blades.[4] Tahul-tahul has been recorded as a local vernacular name for this species.[2]
