Slender, (homeophyllous?), root-climbing liane. Shoot system rather poorly differentiated into adherent non-flowering, and free lateral flowering branches; eocaul & seedling not observed; flowering shoot abbreviated, arising from below the leaf axil of a fully developed leaf, or from an older naked portion of stem, leafless except for subtending foliage leaf, with several well-developed cataphylls. LEAVES thinly chartaceous, drying dull grey greenish; petiole 2–5 cm long, slender, rarely rather stout, sheath weakly prominent, extending to just below geniculum and extending above it by two small ligules; blade 10–25 × 3.5–12 cm, oblong-elliptic, slightly falcate, unequal, occasionally quite strongly so, base subacute to minutely truncate, apex prominently falcate, acuminate to attenuate, briefly apiculate; primary lateral veins arising at c. 35°, intramarginal veins 2 per side, the lowermost arising from the base, outer intramarginal vein remaining very close and parallel to margin, inner vein c. 1 cm distant, both reaching the leaf tip; higher venation fine but very distinctly reticulate. INFLORESCENCE several together; flowering shoots always reiterating and thus several inflorescences at various stages of maturity usually present; peduncle 3–7 cm, rather slender, erect or curving, dull green. Spathe 1–1.2 × 0.7–1 cm, ovate to oblongovate, spreading to slightly reflexed, base rounded, barely decurrent on the peduncle, apex obtuse, very weakly beaked. Spadix sessile to briefly stipitate; stipe 0–2.5 mm long; fertile portion 1–2 × 0.2–0.4 cm, cylindrical, straight to slightly curved, base rounded. Flowers c. 1.1 mm diam., with 6 free tepals and 6 stamens. INFRUCTESCENCE with few berries; fruit c.10 × 5 mm, globose to ellipsoid, ripening deep scarlet; seeds not observed.
