In 1994, A. Wistuba, H. Rischer, B. Baumgartl, and B. Kistler explored Doorman Top in search of N. paniculata but found no Nepenthes other than N. lamii (then known as N. vieillardii) and N. maxima.[6] However, they climbed a different slope to the one from which N. paniculata was originally collected.[6]
In August 2013, the species was rediscovered by a team consisting of Holger Gossner, Thomas Gronemeyer, David Marwinski, Stewart McPherson, Marius Micheler, Joachim Nerz, Andreas Wistuba, and Urs Zimmermann.[7][8][9][5] This expedition was the first to document the lower pitchers, which superficially resemble those of N. merrilliana and species related to it from the Philippines.[10]
