About

Nepenthes inermis is a tropical pitcher plant endemic to the Indonesian island of Sumatra. The specific epithet inermis is Latin for "unarmed" and refers to the upper pitchers of this species, which are unique in that they completely lack a peristome.

Where it grows

Nepenthes inermis is endemic to a number peaks in the Barisan Mountains that line the western side of Sumatra. More specifically, it is known only from the Indonesian provinces of West Sumatra and Jambi. The species has an altitudinal distribution of 1,500–2,600 metres (4,900–8,500 ft) above sea level. It usually grows as an epiphyte in mossy forest, but also occurs terrestrially in stunted upper montane vegetation above 2,000 metres (6,600 ft).
