Nepenthes dubia is a climbing tropical pitcher plant from the highlands of Sumatra, where it grows on mossy montane forest at 1,600 to 2,700 m. It needs cool, humid, bright conditions and is rarely grown in cultivation.
Nepenthes dubia is a tropical pitcher plant endemic to the Indonesian island of Sumatra, where it grows at an elevation of 1,600–2,700 m above sea level. The specific epithet dubia is the Latin word for "doubtful".
Nepenthes dubia was for a long time thought to be endemic to Mount Talakmau, but it was recently found on a second mountain, where it grows at lower elevations of around 1,600 m above sea level. On Mount Talakmau, the species occurs at an elevation of 1,800–2,700 m. At lower elevations on Talakmau, it grows epiphytically in montane forest. However, above around 2,400 m, vegetation is very stunted and here N. dubia also grows terrestrially on clumps of moss.
