Where it grows wild

Upper montane mossy forest and summit scrub. It grows terrestrially, unlike the related N. jacquelineae which is epiphytic, and climbs up to about 4 m on thin stems. It shares its site with N. bongso, N. dubia, N. gymnamphora and N. lingulata, and hybridises naturally with N. lingulata.

Published range is 1800–2100 m. Neither of the two wild records used carries an elevation.
