Slender to rather robust, homeophyllous(?), root-climbing liane to 10 m. Shoot system very strongly differentiated into adherent non-flowering and flowering shoots, the latter completely and densely clothed by inflated, 7–10 × 1.5–2 cm, overlapping cataphylls; eocaul and seedling not observed. LEAVES pale to mid-green adaxially, very slightly paler abaxially; petiole 11–24 cm × 3–6.6 mm, slender, strongly channelled, geniculate apically; blade (7–)0.5–34 × (2.5)5–15 cm, lanceolate-elliptic, strongly oblique, base minutely cordate, apex attenuate with a 2–2.5 mm apiculum; primary lateral veins numerous, arising at 35–45°, intramarginal veins 3 per side, very prominent, the innermost c. ? distant from margin to midrib. INFLORESCENCES few to many together, produced sequentially, each subtended by a robust inflated cataphyll; peduncle 5 cm × 2–3 mm, greenish purple. Spathe 4.5–7.5 × 1.5–3.5 cm, ovate-elliptic, reflexing at anthesis, base decurrent, apex acuminate, mid-green with a broad purple mark centrally and some purple staining apically. Spadix stipitate; stipe 4–6 × 1.5–2 mm, decurrent into spathe limb, purple; fertile portion 4.2–9 × 0.6–1.3 cm, cream. Flowers c. 2.3 mm diam.; tepals 6, free; stamens 6. INFRUCTESCENCE with numerous berries, spathe persistent into fruiting, becoming chartaceous, tepals much increased in size, up to 7 × 2.5 mm, apparently functioning as protection for developing berries, filament remains abundant, chartaceous; fruit 5–10 × 2–3.5 mm, ellipsoid, flattened basally, turbinate apically, young berries dark purple, tinged white, ripe berries white with purplish stylar region, musty fruit-scented; seeds c. 2 × 3 mm, ovoid, greyish brown.
