    Epiphytic or epilithic; stem 1.5-5 cm diam.; roots dense, spreading to descending, tan to greenish, smooth, short, and stubby, 7-10 mm diam.; cataphylls coriaceous, lanceolate, (5)17-23 cm long, acute and apiculate at apex, green, sometimes reddish, drying tan to brown, persisting with apex remaining intact, dilacerating at base. LEAVES erect to spreading; petioles 15-26 cm long, 7-18 mm diam., D-shaped to thicker than broad, broadly sulcate adaxially with the margins sharply raised to obtuse, sharply 1-ribbed to obscurely 3-ribbed or rounded abaxially, the surface pale-speckled; geniculum paler and thicker than petiole, 1-2.5 cm long; blades coriaceous, oblanceolate to oblanceolate-elliptic, short-acuminate at apex (the acumen shortly apiculate), acute to attenuate at base, 32-108 cm long, 10-43 cm wide, broadest above the middle, the margins prominently undulate; upper surface semiglossy, medium green, lower surface semiglossy to matte, much paler; midrib flat to obtusely angular at base, becoming narrowly acute and then flat toward the apex above, prominently higher than broad and 1-ribbed at base, becoming convexly raised toward the apex; primary lateral veins 5-14 per side, departing midrib at 40-55° angle, straight then arcuate-ascending to the margin, convexly raised, much paler than surface above, prominently raised and paler than surface below; interprimary veins less conspicuously raised above, visible and flat below; tertiary veins obscure above, darker than surface below; collective vein arising from near the apex or absent, flat to weakly sunken above, weakly raised and darker than surface below, 6-11 mm from margin. INFLORESCENCES spreading, shorter than leaves; peduncle 32-43 cm long, 9-10 mm diam., 2-2.5 x as long as petiole, subterete, obscurely angled; spathe spreading, subcoriaceous, green, sometimes tinged with purple (B & K yellow-green 6/10 ), ovate to broadly ovate, 13-16 cm long, 6.2-9.7 cm wide, broadest near the base, inserted at 70° angle on peduncle, acuminate at apex, acute at base; spadix green, purple or green heavily tinged with purple (B & K red-purple 2 / 5 ), cylindroid, 9-21 cm long, 11-27 mm diam. near base, 5-7 mm diam. near apex; flowers 4-lobed, 2.4-2.8 mm long, 2.7-3.2 mm wide, the sides sigmoid; 8-14 flowers visible in principal spiral, 12-20 in alternate spiral; tepals matte, weakly punctate, minutely papillate; lateral tepals 1.5-1.8 mm wide, the inner margins convex; pistils slightly raised, green, tinged with purple in the area of stigma; stigma linear, 0.4-0.6 mm long, droplets appearing 4-5 days before stamens emerge; stamens emerging ± rapidly from the base, inclined over the pistil; filaments exserted, ca. 0.3 mm long, 0.8 mm wide; anthers orange; thecae ellipsoid, scarcely divaricate; pollen orange, fading to white (B & K yellow 7/2.5). INFRUCTESCENCE 20-23 cm long, 3 cm diam., pendent; spathe usually persisting, green; berries pale yellow, greenish at tip, irregularly obovoid, 12-15 mm long, 7-9 mm diam.; mesocarp fleshy, with numerous raphide cells; seeds 2 per berry, pale tan, subglobose, weakly flattened, 5-6.5 mm long, 3.5-4.1 mm diam., ca. 2.5 mm thick, with a sticky appendage at both ends.
