Folia mediocria petiolata, lamina elliptica, nervis longitudinalibus utrinque 3-4, vagina in alas 2 decurrente: ascidia rosularum et inferiora ignota ; ascidia superiora infundibuliformia, parte inferiore costis 2 prominentibus, os versus alis 2 fimbriatis ; peristomio operculum versus in collum ; 1-2 cm altum elevato, cylindrico, crebre costato, operculo late cordato, facie inferiore prope basin carina valida ; inflorescentia ignota ; indumentum in omnibus partibus iuventute pubescens, statu adulto parcum v. deciduum, in margine foliorum persistens.

Stems robust, climbing, 12 to 15 m high, 12 to 15 mm thick, sharply triangular, 2-winged, the internodes 7 to 10 cm long, Rosettes unknown. Leaves of the climbing stems scattered, coriaceous, long-petioled ; lamina oblong to lanceolate, 20 to 35 cm long, 6 to 8 cm broad, acute, rather abruptly attenuate at the base ; petiole 7 to 10 cm long, winged, clasping the stem by 1/3 or 1/2 at the base and decurrent into 2 wings over one internode ; pennate nerves ascending ; longitudinal ones 3 or 4 on both sides, running parallel in the outer l/2 or 2/3 part of the lamina ; tendril 20 to 25 cm long, 1 1/2 to 2 mm thick. Pitchers of the rosettes and those of the inferior part of stems unknown. Upper pitchers originating rather abruptly from the tendril, incurved and infundibulate for the rest, 6 to 10 cm high, 3 to 5 cm wide, slightly contracted under the mouth, with 2 prominent ribs in the lower part ; mouth nearly round, horizontal in front, elevated towards the lid ; peristome cylindrical, prolongated into a neck 1 to 2 cm long, 8 to 12 mm broad, delicately ribbed ; inner side of the pitcher wholly glandular with deepened glands or with a glandless triangle below the lid ; lid broadly ovate, undulate at the margin, the underside wholly glandular, the basal part of the midrib keeled ; spur thick and obtuse, 8 to 10 mm long. Inflorescence &c. unknown. Indumentum of the stems first short and brown, later deciduous and leaving brown points, that of the leaves almost none at the upper surface, like that of the stems on the underside, but more sparse ; the margin ferrugineous-pubescent, the tendrils brown-pubescent, the pitchers densely hairy when young, later with sparse spreading hairs and with a densely tomentose ribbon under the mouth, "The colour and translucent texture is that of eggshell porcelain, ivory white, with rose-pink blotches." (Description after that of MACFARLANE, the colour of the pitchers after BURBIDGE, Gard. Chron. 1896, 2, p. 106.)

BORNEO. British North Borneo: Mt. Kinabalu, Mari-pari Spur, 1000-1200 m (ENGL., Pflanzenr., IV, 111, p. 71).

This species has only been found twice on Mt. Kinabalu and is very insufficiently known. I have not ventured to unite it with any other. N. pilosa, though doubtless the most nearly related species, is certainly different.
