Epiphytic; stem to 16 cm long, 7-14 mm diam.; roots dense, 3-5 cm long, 3-4 mm diam.; cataphylls subcoriaceous, linear-lanceolate, 3-13 cm long, drying reddish brown, persisting semi-intact. LEAVES erect; petioles 9-17 cm long, 5-10 mm diam., D-shaped, with the medial rib and margins raised adaxially, angular abaxially; geniculum somewhat darker than petiole when dried, 0.5-1 cm long; sheath 2.5-4 cm long; blades coriaceous, oblong-elliptic, acute to obtuse at apex, attenuate to acute at base, 45-70 cm long, 9-17 cm wide, broadest just above the middle; upper surface apparently quilted, lower surface often tinged red or purple; midrib acutely raised above and below; primary lateral veins 4-9 per side, departing midrib at 50-60º angle, very long-arcuate to the margin or slightly arcuate to the collective vein, raised to obscure above, raised below when dried; interprimary veins usually present, less conspicuous than primary lateral veins; tertiary veins weakly raised obscure above and below when dried; collective vein arising from about the middle of the blade or absent, rarely from near the base, sunken above, raised below when dried, equally as prominent as primary lateral veins, 10-15 mm from margin. INFLORESCENCES erect; peduncle 11-29 cm long, 2-5 mm diam., 1-2.6 x as long as petiole, terete; spathe reflexed, subcoriaceous, green, oblong-lanceolate, 4-10 cm long, 1-2 cm wide, broadest near the base, acute at apex, acute at base; spadix white, cylindroid, ± straight, 5-7 cm long, 4-6 mm diam. midway; flowers ± rhombic, ca. 0.8 mm in both directions; ca. 12-15 flowers visible in either spiral; tepals densely papillate; stamens held erect above the tepals; filaments exserted 0.2 mm; anthers 0.2 mm in both directions. INFRUCTESCENCE spreading-pendent; spathe persisting or absent; spadix 20 cm long, 2 cm diam., with berries scattered throughout; berries purple, tipped white (B & K purple 5/5), obovoid-ellipsoid, obtuse at apex, ca. 7 mm long, ca. 4 mm diam.; pericarp with numerous raphide cells; seeds 1-2 per berry, yellow-brown when dried, oblong, 2 mm long, 1 mm diam.
