SUMMARY
Terrestrial or epiphytic plant; caudex erect, rooting at the nodes; internodes 1–15 cm long, 1–3.5 cm diam., sometimes purplish; cataphylls to 16 cm long, persistent to semi-intact, ultimately weathering to fibres. Leaves erect; petiole unisulcate adaxially from base to apex, 35–75 cm long, 7–8 mm diam., sometimes speckled and tinged purple, geniculate at apex; geniculum to 2 cm long, often darker than petiole; blade elliptic to ovate, obtuse at apex, obtuse, rounded or weakly subcordate at base, 25–51 cm long, 13–23 cm wide, 1.6–2.6 × longer than wide, 0.5–1.1 × as long as petiole, moderately coriaceous, dark green and glossy above, lighter green and semiglossy below, sparsely and weakly glandularpunctuate above and more prominently glandular-punctate below, drying brown; midrib convex and reddish or paler above, in deep valley formed by upturned sides of blade, round-raised and paler or reddish below; primary lateral veins 10–20 pairs, rising at 60–70° angle, quilted-sunken above, prominently pleated-raised and weakly convex below; basal veins 2 pairs, the first soon merging with the leaf margin, the 2nd pair arching towards the leaf apex and running 1–2 cm from margin, ending at the tip; collective veins arising from the first pair of primary lateral veins, running directly along the margin; all veins usually red or purplish. Inflorescences erect or pendent-spreading; peduncle terete with very small adaxial ridge, 37–87 cm long, 4–7 mm diam.; spathe lanceolate, spreading, falling off as fruit develops, 13–18 cm long, 0.7–1.7 cm wide, green, reddish or purplish green; spadix stipitate 1–8 mm, narrowly tapered, 11–45 cm long, 5–15 mm diam., pale green, yellow-green, purplish or brown. Flowers 3–3.7 mm long, 2.6 mm wide, 8–9 visible per spiral; tepals minutely granular, lateral tepals 1.3–1.7 mm wide, outer margins 2-sided, inner margins straight. Infructescences erect; berries early emergent, green when young, usually yellow but sometimes orange at maturity; seeds 2 per fruit.
