Nepenthes villosa is a highland tropical pitcher plant native to the upper slopes of Mount Kinabalu and Mount Tambuyukon in Sabah, Borneo, growing at higher elevations than any other Bornean Nepenthes. It is a weak climber grown for its hairy stems and leaves and its fringed pitchers, and it needs cool, humid, bright conditions to thrive.

About
Nepenthes villosa , or the villose pitcher-plant, is a tropical pitcher plant endemic to Mount Kinabalu and neighbouring Mount Tambuyukon in northeastern Borneo. It grows at higher elevations than any other Bornean Nepenthes species, occurring at elevations of over 3,200 m (10,500 ft). Nepenthes villosa is characterised by its highly developed and intricate peristome, which distinguishes it from the closely related N. edwardsiana and N. macrophylla.
The specific epithet villosa is Latin for "hairy" and refers to the dense indumentum of this species.
Where it grows
Nepenthes villosa is endemic to the upper slopes of Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah, Borneo. It generally grows at 2,300–3,240 m above sea level, the highest elevation of all Bornean Nepenthes species; only N. lamii from New Guinea is found at greater elevations. On Mount Kinabalu, N. villosa is common along the Mesilau Trail (between Pondok Magnolia and the meeting point with the old summit trail) and almost all the way up to the Laban Rata rest house; a particularly large population has been reported at around 3047 m. On Mount Tambuyukon, an altitudinal inversion has been noted, whereby N. villosa is more common at much lower elevations of 1600–1900 m, being replaced by N. rajah towards the summit. The exposed, uppermost slopes of Mount Tambuyukon can become very hot during the day and this might explain the inability of N. villosa to colonise them. Plants from Mount Tambuyukon generally produce slightly more elongated pitchers.
