This hybrid differs from "N. fusca" in the presence of bristles on the underside of the lid. Conversely, it has a dense indumentum on the stem and at the margins of the lamina, compared to the virtually stem and leaves of "N. lowii". It also differs from "N. lowii" in having a more developed peristome, which is circular in cross section. While lower pitchers of "N. lowii" have prominent teeth, those of "N. fusca" × "N. lowii" are indistinct. In addition, a glandular appendage is present on the underside of the lid, a trait inherited from "N. fusca".
