LEAVES coriaceous, deep-green, paler abaxially, drying mid-green to brown; petiole 1.5–4 × 0.1–0.2 cm, rather stout, apex prominently geniculate, sheath mostly indistinct, occasionally spreading and apically ligulate in very large leaves; blade 4–26 × 1.5–6 cm, narrowly oblong elliptic to narrowly elliptic, very occasionally slightly unequal and falcate, apex acuminate to long-acuminate, apiculate, apicule later deciduous, base acute to obtuse; primary lateral veins arising at 70–80°, 2 intramarginal veins per side, 2–10 mm from blade margin, arising from just above base of the midrib, remaining ± parallel to margin, terminating at the tip of the blade. INFLORESCENCES several at different stages on a reiterating flowering shoot; peduncle 1–2.5 × c. 0.1 cm, slender, strongly curving or straight, the inflorescence held erect, purple-green. Spathe 0.8–1.5 × c. 0.6 cm, ovate, base rounded, annularly inserted on to peduncle, apex acuminate, reddish pink. Spadix stipitate; stipe 5–20 × 0.5–0.8 mm, terete, pubescent, yellow to dark pink; fertile portion 3–8 × 0.2–0.3 cm, very slender-cylindric, pubescent, straight to markedly zig-zagging (even on same synflorescence), yellow to dark pink. Flowers c. 1.8 mm diam., widely scattered, arranged in a lax spiral along the spadix with 6 free tepals and 6 stamens. INFRUCTESCENCE with few berries; fruit 8–9 × 4–5 mm, oblong-ellipsoid; seeds not observed.
