    Description

    Terrestrial climber to c. 2 m tall. Rosette and short stems unknown.Climbing stems terete, internodes (3.5–)4.5–5.5 cm long, (2.5–)4–5 mm diam, drying black, c. 50 % covered in persistent patent pale brown hairs 0.5–0.6 mm long, hairs simple, multicellular, mixed with sessile depressed globose glands drying black, 0.06 mm diam. Leaf blades of climbing stems coriaceous, sessile, lanceolate-oblong, (12.5–)14–17(–21.5) by 2.7–3.2 cm, apex acute, subpeltate, base perfoliate-adnate, decurrent by (0.9–)1.5–1.8 cm. Longitudinal nerves 2 pairs, in the marginal half, visible on both surfaces. Pennate nerves inconspicuous, irregular, patent to midrib, 5–8 mm apart. Indumentum of upper surface as the stem, but sometimes with a minute, inconspicuous branch 0.05 mm long, cover 5 %, hairs 0.3 mm long, midrib with 30–50 % cover, hairs 0.5 mm long; lower surface 50 % cover, hairs 0.3–0.5 mm long, denser on midrib. Tendrils (10 –)15 –17(– 20) cm long, densely patent hairy, indumentum as stem. Upper pitchers (tendrils coiled) cylindrical 11–15 by (1.7–)2–3 cm, green, slightly suffused with purplish red, wings running full length of pitchers, 3–5 mm wide, fringed only in upper 1/2–1/5, fringe elements 2–4 mm apart, 1–1.5 mm long, outer surface 2–50 % covered in a mixture of indumentum as stem, densest at pitcher base. Mouth rhombic, obtuse; straight, not concave, inner surface waxy white-grey; peristome 0.5–0.9 mm diam, ridges blade-like, in overall length to 1.8–2.5 mm diam, c. 1 mm high, 1–1.5 mm apart, column absent; lid elevated 45° above the horizontal, 90° above the mouth, ovate-elliptic 2.5–3.5 by 1.5–2 cm, lower surface without appendages, densely covered in orbicular and elliptic, thinly bordered nectar glands 0.2–0.25 mm diam, midline ridge at base with narrow elliptic nectar glands 0.6 by 0.06 mm, mixed with depressed globose glands 0.03 mm diam (drying black); hairs 2–7 per mm2, patent, copper-coloured, simple or inconspicuously branched (0.2–)0.3–0.6(–0.8) mm long; spur dorsiventrally flattened, oblong-acute, slightly recurved, 4–5 by 1.5 mm, flanked by 1–2 cylindrical appendages of same length. Male inflorescence c. 15 by 2.5 cm, peduncle c. 6 cm long, 2 mm diam at base, 50 % covered in mainly appressed copper-coloured hairs 0.2 mm long; rachis c. 9 cm long, with c. 80–84 partial peduncles, partial peduncles 1-flowered, 4–7.5 mm long, 0.5 mm wide; bracts present on pedicels of proximal c. 60 flowers, each 0.8–1 mm long, acute, inserted 0–2.5 mm from base of partial-peduncle; flower colour unknown; tepals 4, oblanceolate-obovate, 3.5–4 by 1.5–1.9 mm, apex rounded, outer surface 5 % covered in minute copper-coloured simple appressed hairs 0.05 mm long, densest on margins; adaxial surface with nectar glands occupying c. 50 % of surface, glands elliptic, c. 0.25 by 0.15 mm, cohering or up to 0.1 mm apart, thinly bordered, deeply sunken; androphore terete, 5 mm long, 0.3 mm wide, glabrous; anther head 1–1.5 by 1.5–1.75 mm, anthers 4, in a single whorl, head of androphore conspicuous, glabrous. Female inflorescence, infructescence and seed unknown. A
