Botanist Clive A. Stace writes that one may speak of "stabilised hybrids when they have developed a distributional, morphological or genetic set of characters which is no longer strictly related to that of its parents, [...] if the hybrid has become an independent, recognisable, self-producing unit, it is "de facto" a separate species". This would tend to support the status of "N. murudensis" as a species, since populations of this taxon appear to be stabilised as well as highly , and it is one of the most abundant "Nepenthes" on the summit ridge of Mount Murud. Examples of other "Nepenthes" species with a putative hybrid origin include "N. hamiguitanensis", "N. hurrelliana", and "N. petiolata".
