Tall, slender root-climbing liane or hemi-epiphyte. Shoot system architecture unknown. LEAVES with the petiole 2–5 cm long, prominently geniculate at the apex, sheathing for most of its length, sheath persistent; blade c. 12–16 × 2–4 cm, lanceolate, somewhat oblong and falcate, rather stiff, tip acuminate, base acute; primary lateral veins diverging at c. 30–60°, intramarginal veins one on each side of the midrib, submarginal. INFLORESCENCE a lax, compound, much-ramified, sympodial synflorescence, the modules consisting of a prophyll, 3 or 4 cataphylls, a terminal inflorescence and a relay bud in the axil of the last cataphyll — the lower cataphylls sometimes with similar modules in their axils; synflorescence cataphylls lanceolate, 6–12 mm long; peduncle c. 2–4 cm long, very slender, subtended by a cataphyll almost as long. Spathe 3.5–4 cm long, ovate-lanceolate, acuminate, about twice the length of the spadix. Spadix sessile, to c. 2 cm × c. 3 mm, cylindrical; flowers c. 1.6 mm diam., with 6 free tepals and 6 stamens. INFRUCTESCENCE with 4–6 berries; fruit globose, c. 5 mm diam.
