Terrestrial climber to 10 m tall. Stem of short, non-climbing shoots with stem terete, 1.1-1.5 cm diam., internodes c. 2 cm long; climbing stems D-shaped, semi-circular, or subtriangular in cross section, 0.7-1.2 cm wide, with two wings 1-9 mm wide, internodes 7-10 cm long, the wings running the length of the internode, stopping just above the node to 9 mm wide; axillary buds prominent, rarely absent, cylindrical, slender, 2-5.5 mm long, acute, inserted c. 1 cm above the axil. Leaves of short stems distinctly long petiolate, oblong, 44-50 by 9-11.5 cm, apex acute, base attenuate; petiole 10-17 by 0.9 cm, canaliculate, the margins sheathing and clasping the stem for 5/6 its circumference; leaves of climbing stems elliptic-lanceolate, 13-25 by 3.8-7.5 cm, apex acute, base acute to rounded; petiole 6-11 cm long, semi-circular in cross section, the upper surface flat, 4-10 mm wide, ± winged, clasping the stem for 1/3-1/2 its diameter and decurrent into two wings. Longitudinal nerves 1 or 2 on each side of the midrib in the outer 1/4 of the blade. Pennate nerves numerous, patent. Lower pitchers ellipsoid or ovoid, 19-25 by 8.5-10 cm, wings 5-7 mm wide, with fringe elements 3-6 mm long, 2-3 mm apart; mouth obliquely concave; peristome broad, subcylindrical to slightly flattened, c. 20-30 mm wide, with fine ribs 0.6 mm apart, 0.1-0.2 mm high, outer surface sinuate, inner surface with teeth c. 1 mm long; lid ovate, 7-9.5 by 6.4-9 cm, apex round, base cordate, margin straight, lower surface densely uniformly glandular, excepting the non-glandular marginal 0.9 cm, glands volcano-like, 0.3 mm diam.; lower surface of lid with base keeled, bearing a rounded appendage 3-14 mm high from a ridge up to 18 mm long; spur c. 15 mm long, unbranched. Upper pitchers shortly infundibuliform, 7.2-11 by 5-8 cm, arising abruptly from the tendril, dilating to 1 cm and curving for 3-4 cm before expanding, slightly contracted below the peristome, lacking fringed wings but with two prominent ridges 1(-2) mm wide, these rarely, then in the upper part only, with fimbriae 1.5 mm long, 1-2 mm apart; mouth round, horizontal, abruptly rising at the rear into a neck c. 1 cm long; peristome cylindrical, (1-) 2.5(-4) mm broad, with ribs 0.1 mm high, 0.2-0.3 mm apart, outer edge not sinuate, inner edge lacking teeth; lid ovate, 2.5-6.5 by 2.6-5.2 cm, apex rounded, base cordate, margin slightly sinuate, lower surface uniformly, densely glandular, glands circular to slightly elliptic, rimmed, 0.15-0.2 mm diam., midline keeled at base, the appendage 1.5-10 mm high from a raised ridge 4-15 mm long; spur c. 10 mm long, unbranched or shortly bifurcate. Inflorescence (fide Kurata 1976) 25-35 cm long, partial peduncles 2-flowered, pedicels 10-15 mm long. Fruits and seeds unknown. Indumentum of sessile red glands 0.1 mm diam. on stem, petiole, lower surface of leaf blade, outer pitcher and upper lid; intermixed with simple red hairs 0.5 mm long on outer pitcher, upper lid and on spur; dark brown 1- or 2-branched hairs 0.6-1 mm long line the edge of the leaf blade and the petiole wing. Colour of lower pitchers pale green, streaked and blotched red or purple, peristome with numerous red stripes; upper pitchers translucent white or pale yellow, speckled or blotched with red or purple. Inflorescence colour unknown.A


Nepenthes burbidgeae, on account of its shortly infundibuliform, translucent, porcelain white, lightly red-flecked upper pitchers is unlikely to be confused with any other species on Mt Kinabalu. It is part of the N. maxima group, as evidenced by the appendage on the lower surface of the lid, and the distinctly petiolate leaves with prominent axillary buds. Although well-known to nepenthophiles through Kurata, Nepenthes of Mount Kinabalu (1976: 40), this species is represented by only a few incomplete sheets: we have found no fertile material of N. burbidgeae and lower pitchers are represented by only two collections.A


A hybrid with N. rajah has been named Nepenthes × alisaputrana J.H. Adam & Wilcock.A
