Habitat
Primary to degraded secondary lowland to lower montane forest.
General Description
Very robust, vigorous, moderately ramified semi-heterophyllous root-climbing liane to 30 m. Shoot system weakly or not differentiated into non-flowering and flowering branches; eocaul foraging and climbing, often very long with occasional stretches of a few shingling leaves; seedling shingling. LEAVES mid-green, semi-glossy above, stiffly chartaceous to coriaceous, drying pale grey-yellowish green; petiole (1–)5–16 × 0.5–1.3 cm, rather stout, sheath prominent, extending to just over the base of the apical geniculum, lower portion clasping stem; blade (3–)8.5–27 × (2.5–)7–27 cm, spreading, oblong ovate to very broadly ovate, oblique, sometimes profoundly so, apex acuminate to obtuse, ultimately with a stout tubular mucro, base broadly rounded to narrowly cordate; primary lateral venation diverging at c. 60–80°, crossed by usually three intramarginal veins on each side of the midrib, these arising from near the base of the midrib and running more or less to the leaf tip. INFLORESCENCE solitary at the end of leafy, pendulous shoots; peduncle 9–15 cm, about equalling the petiole of the subtending leaf, most of it within the sheath at flowering. Spathe 14–23 × 3–5 cm, somewhat exceeding the spadix, narrowly lanceolate to narrowly elliptic, distally somewhat twisted, membranous, green. Spadix conspicuously stipitate; stipe c. 2–4 × 0.15–0.2 cm; fertile portion 9–20 × 0.7–1.4 cm, long-cylindrical, brownish yellow-green or purple. Flowers c. 2.5 mm diam.; with 6 free tepals and 6 stamens. INFRUCTESCENCE elongated, to c. 17 cm long, pendulous, with many berries; fruit 1.4–2.5 × 1–1.5 cm, ovoid, to scarlet when ripe; seeds c. 3.5 × 5 mm, ellipsoid, pale greenish brown.
