The species is also present on Mount Tahan, which at 2187 m is the highest mountain in Peninsular Malaysia. Its altitudinal range on Mount Tahan is known to extend from 800 to 1350 m. It is common on the mountain's lower slopes and can be seen along the western summit route from Sungai Relau, particularly on the tops of steep ridges at around 800-1200 m. It has been recorded growing along the western trail itself and from other disturbed sites, including areas affected by landslides. Plants have also been observed in dense forest, but these bear comparatively few pitchers. Though there were no confirmed reports of N. benstonei from Mount Tahan prior to 2012, the species's presence there is attested by much older herbarium material.
