''Nepenthes khasiana'' (; after the Khasi Hills, to which it is largely endemic) is a 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.〔Kurup, R., A.J. Johnson, S. Sankar, A.A. Hussain, C.S. Kumar & S. Baby 2013. Fluorescent prey traps in carnivorous plants. ''Plant Biology'' 15(3): 611–615. 〕 The species has a very localised distribution and is rare in the wild. 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. Nevertheless, ''N. khasiana'' exhibits considerable genetic diversity.〔Bhau, B.S., K. Medhi, T. Sarkar & S.P. Saikia 2009. PCR based molecular characterization of ''Nepenthes khasiana'' Hook. f.—pitcher plant. ''Genetic Resources and Crop Evolution'' 56(8): 1183–1193. 〕 The Khasi people call the plant ''tiew-rakot'', which means ''demon-flower'' or ''devouring-plant''. The Jaintias call it ''kset phare'', which is roughly translated as ''lidded fly net''. The Garo call the plant ''memang-koksi'', which literally means ''the basket of the devil''.〔〔(Flora of Meghalaya )〕 ''Nepenthes khasiana'' is a protected species, classified as Endangered, and is on CITES Appendix I along with ''N. rajah''. Threats to wild populations include habitat destruction, acid mine drainage associated with coal mining, and collection for medicinal and ornamental uses.〔Prasad, M.N.V. & S. Jeeva 2009. (Coal mining and its leachate are potential threats to ''Nepenthes khasiana'' Hook. f. (Nepenthaceae) that preys on insects - an endemic plant in North Eastern India. ) ''Biological Diversity and Conservation'' 2/3: 29–33. 〕〔Verma, P.K., J. Schlauer, K.K. Rawat & K. Giri 2014. Status of insectivorous plants in northeast India. ''Carnivorous Plant Newsletter'' 43(2): 49–58.〕 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''.〔Ziemer, B. 2010. Exciting conservation news: the Rare ''Nepenthes'' Collection project! ''Carnivorous Plant Newsletter'' 39(3): 67.〕〔(''Nepenthes khasiana'' ). Ark of Life.〕〔Bourke, G. 2010. ''Captive Exotics Newsletter'' 1(2): 5–6. 〕 The specific epithet ''khasiana'' is spelled ''khasyana'' in some older texts.〔Moore, D. 1872. (On the culture of ''Nepenthes'' at Glasnevin. ) ''The Gardeners' Chronicle and Agricultural Gazette'' 1872(11): 359–360.〕〔Masters, M.T. 1872. (The cultivated species of ''Nepenthes''. ) ''The Gardeners' Chronicle and Agricultural Gazette'' 1872(16): 540–542.〕 This spelling actually predates that under which the species was formally published in Joseph Dalton Hooker's 1873 monograph, "Nepenthaceae",〔 as it appeared in an article by Maxwell T. Masters in the April 20, 1872 issue of ''The Gardeners' Chronicle and Agricultural Gazette'' (this article was itself based on the manuscript of Hooker's monograph).〔 In the horticultural trade of the late 19th century, ''N. khasiana'' was often confused with ''N. distillatoria'' of Sri Lanka.〔〔Masters, M.T. 1881.
