|}} ''Nepenthes angasanensis'' is a tropical pitcher plant species endemic to Sumatra, where it grows at an altitude of 2200 to 2800 m above sea level.〔McPherson, S.R. & A. Robinson 2012. ''Field Guide to the Pitcher Plants of Sumatra and Java''. Redfern Natural History Productions, Poole.〕 The status of this taxon is controversial as it is similar in morphology to ''N. mikei'' and ''N. tobaica''. It has even been suggested that the taxon might represent a natural hybrid between ''N. densiflora'' and ''N. tobaica''.〔Schlauer, J. (''Nepenthes angasanensis'' ). Carnivorous Plant Database.〕 The specific epithet refers to Mount Puncak Angasan, from which the type specimen was collected.〔 No forms or varieties of ''N. angasanensis'' have been described. ==Taxonomy== In 2001, Charles Clarke performed a cladistic analysis of the ''Nepenthes'' species of Sumatra and Peninsular Malaysia using 70 morphological characteristics of each taxon. The following is a portion of the resultant cladogram, showing part of "Clade 6". The sister pair of ''N. angasanensis'' and ''N. mikei'' has 79% support.〔Clarke, C.M. 2001.
