Nepenthes khasiana (

endemic) is an endangered tropical pitcher plant of the genus Nepenthes. It is the only Nepenthes species native to India. It is thought to attract prey by means of blue fluorescence.[4]

The species has a very localised distribution and is rare in the wild. But with new advancement in agro-technology and tissue culture, it is now being cultivated in campus of Nagaland University, Nagaland. These Pitcher Plants which are endemic to Meghalaya can be seen widely as decorative plants outside many houses of Nagaland.[5]

Isolated populations are known to occur in the Jarain area of the

Jaintia Hills, the Baghmara area of the Garo Hills, adjacent to the Khasi Hills region of Meghalaya, in the Upper Kharthong area, of Dima Hasao district Assam and in some parts of Nagaland.[6]

Nevertheless, N. khasiana exhibits considerable genetic diversity.[7] The

Garo call the plant memang-koksi, which literally means the basket of the devil[8][9] and the Biate tribe of Assam call the plant Jug-Par which means Jug-flower or Loisul Kola which literally means Pitcher-plant.[6]

Nepenthes khasiana is a protected species, classified as

endangered,[1] and is listed under CITES Appendix I meaning commercial international trade is prohibited.[2] Threats to wild populations include habitat destruction, acid mine drainage associated with coal mining, and collection for medicinal and ornamental uses.[8][10] In 2010, the Rare Nepenthes Collection was established with the aim of conserving 4 of the most threatened Nepenthes species: N. aristolochioides, N. clipeata, N. khasiana, and N. rigidifolia.[11][12][13]

The

The Gardeners' Chronicle and Agricultural Gazette (this article was itself based on the manuscript of Hooker's monograph).[15] In the horticultural trade of the late 19th century, N. khasiana was often confused with N. distillatoria of Sri Lanka.[15][16][17][18]
