"Nepenthes globamphora", which is now considered to be a heterotypic synonym of "N. bellii", was described by Shigeo Kurata and Masami Toyoshima in a 1972 issue of "The Gardens' Bulletin Singapore". The holotype of this taxon, designated as "Kurata & Toyoshima 1128", was collected on August 22, 1965, from Mount Legaspi in Surigao del Sur, Mindanao, at an elevation of 270 m. It is deposited at the herbarium of the Nippon Dental College (NDC). A very early mention of "N. globamphora" (at the time a "nomen nudum" as the taxon was undescribed) appeared in a 1966 issue (volume 36, page 15) of "The Journal of Insectivorous Plant Society".
