Description

Stem climbing, slender, terete, c. 4 mm diam., intemodes 3-7.5 cm long. lndumentum red-brown, consisting of dense, short, branched hairs c. 0.2 mm long mixed with scattered, longer, basally branched hairs c. 0.5-0.8 mm long, on stems, petioles, tendrils and pitchers, longer hairs on the pitchers appressed; surfaces of leaf blade only with scattered simple hairs c. 0.5 mm long, with longer hairs, to c. 1 mm long, present along the margins. Leaves coriaceous, petiolate; petiole canaliculate, 2.5-3.5 cm by 5-7 mm, at the base decurrent on the stem for 5-7 mm, this part slightly wing-like dilated; leaf blade oblong to narrowly obovate-oblong, 8-12.5 by 2.4-4.3 cm, base cuneate, apex slightly oblique, acute; longitudinal nerves 2 on each side of the midrib close to the outer margin, inconspicuous, arising from pennate nerves in basal third, pennate nerves numerous, patent, curved, inconspicuous. Tendrils about as long as the combined petiole and leaf blade, with a coil near the middle. Pitchers, including the lid, greenish cream with deep dull red-purple blotches, peristome light yellow with many red stripes. Lower pitchers cylindrical, gradually tapering to the base, at c. 1/3 above the base with a very slightly thickened annular zone, broadly and weakly constricted in the middle, only slightly widened towards the mouth, 9-9.5 by 1.3-1.5 cm, near the mouth with or without two very short fringed wings, the wings 1-7 mm long, c. 1.5 mm wide, the fringe segments 2-3 mm long, 0.1-1.5 mm apart; mouth broadly ovate, elevated towards the lid; peristome flattened-semicylindrical, c. 2 mm wide in front, c. 3 mm wide at the back, finely ribbed, the ribs c. 0.3 mm apart, inner margin denticulate, with a gland between adjacent teeth, outer margin entire; lid orbicular, 1.2-1.5 by 1.5-1.6 cm, base cordate, apex broadly rounded, both surfaces without appendages, nectar glands of the lower surface absent in the centre or almost so, scattered elsewhere, orbicular, rimmed, c. 0.13 mm across; spur 2-3.5 mm long, at 2.5-3 mm below the lid, unbranched. Upper pitchers infundibuliform, gradually tapering to a long narrow base, 7.5-9 by 2.5-2.7 cm, without wings but with two somewhat prominent ridges; peristome flattened, 4-5 mm wide in front, 5-7 mm wide at the back, finely ribbed, the ribs c. 0.25 mm apart, inner margin weakly obtusely denticulate, eglandular, outer margin entire; lid ovate, 2-2.6 by 1.5-1.9 cm, base cordate, apex obtuse, both surfaces without appendages, nectar glands of the lower surface absent in the centre or almost so, scattered elsewhere, orbicular to elliptic, rimmed, 0.14-0.2 mm across; spur 3-5 mm long, at 2-4 mm below the lid, unbranched. Male inflorescence 12.5 cm long, racemose, c. 50-flowered; peduncle 4.5 cm long; pedicels 1-flowered, 6-10 mm long, bracts absent; tepals elliptic, c. 2.6 by 1 mm; androphore 2.3 mm long, anther head c. 1.3 by 1.6 mm.
