Characteristics

Terrestrial climber, height unknown. Stem terete 0.2-0.4 cm diam., internodes 5.5-13 cm long; axillary buds conspicuous, 0.15-0.7 cm above axil. Leaves coriaceous, sessile; leaves of short stems narrowly lanceolate to lanceolate-spathulate, to 15 by 2.5 cm; apex acute, rarely sub-peltate; base more or less parallel-sided, ultimately with rounded auricles; leaves of climbing stems 7.5-15 by 1-3 cm, as the short-stem leaves, but lacking auricles, the base clasping the stem for 1/3-1/2 its circumference, rarely decurrent. Longitudinal nerves indistinct in dried leaves, 2 or 3 on each side of the mid-rib, in outer 1/3 of blade, arising from base, and sometimes along the midrib. Pennate nerves few, indistinct, arising obliquely and curving towards apex. Lower pitchers unknown. Upper pitchers utriculate, basally infundibuliform, obovoid above; to 9 by 3.5 cm; wings lacking; mouth almost vertical, lateral, not apical, ovate, to 2 cm wide; peristome externally rounded, to 1.5 mm wide, internally flattened, to 8 mm, broadening within, ribs 0.5-0.8 mm apart, inner margin entire, with large glands between ribs; spur simple, c. 9 mm long, apex with 2-4 acute points; lid orbicular, c. 2.7 by 2.1 cm, apex rounded to emarginate, base slightly cordate, lower surface lacking appendages, nectar glands evenly scattered, thinly bordered, circular or shortly elliptic, c. 0.3 mm diam., somewhat larger and denser on midline, the rims distinctly asymmetric, being highest toward lid apex. Inflorescence, fruit and seed unknown. Indumentum inconspicuous, of short, irregularly branching or simple, appressed white hairs to 0.2 mm long, in leaf axils, on midrib and on pitcher particularly around the peristome, and on the lid; lower leaf blade with sessile glands. Colour of pitchers green with brown-red flecks, becoming denser towards mouth, conspicuous in dried specimens; peristome dark red-brown.
