The ICPS partially funded the establishment of The Rare Nepenthes Collection, which aims to conserve four of the rarest Nepenthes species: N. aristolochioides, N. clipeata, N. khasiana, and N. rigidifolia.
Isolated populations are known to occur in the Jarain area of the Jaintia Hills and the Baghmara area of the Garo Hills, adjacent to the Khasi Hills region of Meghalaya.
