In an article published in 1973 on the "Nepenthes" of Borneo, Singapore, and Sumatra, botanist Shigeo Kurata incorrectly identified specimens of a natural cross between "N. inermis" and "N. talangensis" as belonging to "N. dubia". Kurata would later describe this hybrid as a new species, "N. pyriformis".
