Nepenthes inermis is a highland species from West-Sumatra. The species is unique for having only a very rudimentary peristome in the upper pitchers. Upper pitchers are yellow-green and infundibuliform. The lower pitchers have a well developed broad peristome, somewhat similar to N. dubia. Note the characteristic shape of the pitcher lid. Photographs were taken in 1989 on Gunung Gadud and Gunung Gadang, both in West-Sumatra.
