SUMMARY
Hemiepiphyte; caudex elongated with long roots spreading from the nodes; internodes short, 0.7–1 cm diam.; cataphylls to 10.5 cm long, drying pinkish when young, soon deciduous with a few short pale fibres remaining on the upper nodes, remaining intact only on the uppermost node. Leaves clustered at the apex of the caudex; petiole sulcate with angular edges upon drying, glossy, 11–18 cm long, c. 2 mm diam., drying light green; geniculum c. 7 mm long, darker than the petiole; blade oblong- oblanceolate, tapered into a long acumen at apex, cuneate at base, 42–49 cm long, 5–7.2 cm wide, averaging 46 × 6.4 cm, 6–9.1 × longer than wide, 2.6–4.2 × longer than petiole, subcoriaceous, drying grey-green to brownish and semiglossy above, greyish yellow-green and nearly matte below; midrib sharply raised and concolorous above, paler and rounded below; primary lateral veins 18–25 pairs, arising at 50–80° angle and arching towards the apex, flat to slightly raised above, narrow-raised below; collective veins arising from the first pair of basal veins, 2–5 mm from margin; basal veins 1 main pair, sometimes with a weak 2nd pair near the base. Inflorescence erect; peduncle terete, 14–29 cm long, 1–2 mm diam., 1.3–1.75 × longer than the petioles; spathe linear-lanceolate, reflexed, 4.5–7 cm long, 4–8 mm wide, green; spadix stipitate for 2–3 mm, narrowly cylindrical and curved, 10–14 cm long, 3–4 mm diam., greenish to purplish. Flowers 5 visible per spiral, 1.8–1.9 mm long, 1.3–1.4 mm wide; tepals weakly papillate, sometimes pitted, sometimes with pale inclusions on drying, lateral tepals broadly 2-sided outside, broadly rounded inside; stigma drying broadly cup-shaped, 0.3 mm diam. Infructescence erect; berries ovoid, green, projecting out from the thin spadix.
