Folia mediocria sessilia, lamina obovato-lanceolata, nervis longitudinalibus utrinque 5-6, basi 1/2-2/3 caulis amplectente ; ascidia rosularum et inferiora ignota ; ascidia superiora subcylindrica, costis 2 prominentibus ; peristomio in collum breve elongato, cylindrico, 2-3 mm lato, costis dentibusque crebris ; operculo orbiculari, facie inferiore levi ; inflorescentia ignota ; indumentum iuventute densum, ferrugineum v. fuscum, pubescens v. tomentosum, denique parcum, passim permanens.

Stems climbing, the part with adult leaves 4 to 6 mm thick, triangular. Rosettes and short shoots unknown. Leaves of the climbing stems sessile ; lamina obovate-lanceolate, 18 to 25 cm long, 3 to 4 cm broad, acute, the base clasping the stem for 1/2 to 2/3, not decurrent ; longitudinal nerves 5 or 6 on both sides, occupying the greatest part of the lamina, pennate nerves running obliquely towards the margin ; tendril 15 to 20 cm long. Pitchers of the climbing stems almost tubulose, gradually widened towards the mouth, 10 to 12 cm high, 2 1/2 to 3 cm wide, with 2 prominent ribs or 2 narrow, not fringed wings ; mouth oblique, nearly round, somewhat ovate, acute towards the lid ; peristome cylindrical, 2 to 3 mm broad, delicately ribbed, the interior margin minutely toothed ; inner surface of the pitcher shining in the lower 5/6 to 7/8, glandless in the upper portion of the shining part, with few scattered glands in the middle portion, with sparse, large, deepened glands in the lower part ; lid suborbicular, 3 to 3 1/2 cm broad, with few large irregularly scattered glands on the lower surface ; spur 4 to 5 mm long. Inflorescence unknown. Indumentum: the stems brown-velvety when young, only more or less pubescent in the upper part when adult ; leaves glabrous above, the more or less pubescent midrib excepted, almost glabrous below, the short-hairy midrib excepted ; pitchers brown-pubescent towards the mouth, the lid brown-pubescent.

BORNEO. Labuan (ENGL,. Pflanzenr., IV, 111. p. 58).

This species, only known to me from the original description by MACFARLANE, is certainly nearest related to N. leptochila and N. hirsuta, though it seems not possible to identify it with one of them.
