Slender, (heterophyllous?), root-climbing liane. Shoot system architecture unclear; eocaul and seedling not observed; flowering shoot much abbreviated (foliage) leafless. LEAVES chartaceous to somewhat coriaceous, drying greenish brown; petiole 0.4–3 × 0.1–0.12 cm, slender, very narrow-canaliculate, apex weakly geniculate, sheath distinct, prominent, erect, apically ligulate in young growth, ligule later disintegrating; blade 6–21 × 1–4.5 cm, very narrowly to narrowly elliptic, oblique, weakly falcate, apex long-acuminate, apiculate, apicule later deciduous, base obtuse; primary lateral veins arising at 60–70°, 2 intramarginal veins per side, 2–8 mm from blade margin, arising from just above base of the midrib, remaining ± parallel to margin, terminating at the tip of the blade. INFLORESCENCE solitary, rarely several at different stages on a reiterating flowering shoot; peduncle 0.3–1.3 × 0.05–0.1 cm, very slender, pale green. Spathe c. 3 × 2 mm, oblong-ovate, cucullate, base rounded, apex acuminate, white. Spadix stipitate; stipe 1–7 mm long, terete; fertile portion 0.3–0.5 cm, very slender-cylindric, white. Flowers usually 3, seldom more than 5, per inflorescence, c. 1 mm diam., slightly scattered, with 6 free tepals and 6 stamens. INFRUCTESCENCE with few fruits; fruit (immature) 3–5 × 2–3 mm, obclavate ellipsoid; seeds not observed.
