The Nepenthaceae of the Netherlands Indies
"Nepenthes inermis" was first illustrated in an issue of "De Tropische Natuur" published in 1927. A year later, B. H. Danser formally described "N. inermis" in his seminal monograph "The Nepenthaceae of the Netherlands Indies". He wrote: "This new species is easily distinguishable from all others by the peculiar pitchers without peristome and with very narrow lid. Probably it is most nearly related to "N. Bongso"."
