Slender to moderately robust, root-climbing liane. Shoot system well-differentiated into adherent, climbing shoots and free, lateral flowering branches; eocaul not observed; seedling with congested leaves similar in shape to adult, but with blade elliptic and as long as petiole, becoming progressively larger as shoot extends. LEAVES dull pale green above; petiole 2–15 cm × 7–14 mm, exceeding the blade in length, oblanceolate, distally rounded to truncate to auriculate; blade (0.3–)1.5–5.5 cm × (2–)3–25 mm, elliptic to narrowly lanceolate, somewhat acuminate-tipped, base rounded; primary lateral veins diverging at c. 30–40°, intramarginal veins 2 (or 3) on each side of the midrib. INFLORESCENCE solitary, terminal on leafy branchlets; peduncle rather stout, c. 2–5 cm long. Spathe c. 6–11 cm × 6–10 mm, ± lanceolate, wide opening to reflexed, purple-black to greenish. Spadix sessile, 4.8–12 cm × 5–9 mm, rather stoutly cylindrical, brownish purple. Flowers c. 1.3 mm diam., with 6 free tepals and 6 stamens. INFRUCTESCENCE with many berries, usually twisted; fruit 1–2 cm × c. 8 mm long, obovoid, red when ripe; seeds ellipsoid, c. 1 cm × 6 mm, mid-brown.
