SUMMARY
Epiphytic; stem short, 1-2 cm diam.; leaf scars conspicuous, 0.7 cm high, 0.9 cm wide; roots numerous, dense, descending to spreading or ascending, white to pale green, smooth, moderately elongate and slender, blunt, to 11 cm long, 2-4 mm diam.; cataphylls subcoriaceous, lanceolate, 5.5-15 cm long, acute to caudate-acuminate at apex, light green, drying reddish brown (B & K yellow 6/2.5), persisting intact, eventually deciduous. LEAVES erect to spreading; petioles 2.5-9 cm long, 6-10 mm diam., D-shaped, broadly sulcate adaxially, margins blunt to sharply raised, rounded abaxially, the surface pale-speckled; geniculum thicker and paler than petiole, becoming fissured transversely with age, 0.5-2 cm long; blades subcoriaceous, oblanceolate to broadly oblanceolate, long-acuminate at apex, attenuate to acute to narrowly rounded at base, 19-84 cm long, 3.5-21 cm wide, broadest above the middle, the margins broadly undulate; upper surface matte to semiglossy, medium green, lower surface semiglossy to glossy, slightly paler, drying matte, brown, occasionally greenish; midrib flat at base, becoming sharply acute-raised toward the apex above, higher than broad to round-raised at base below, becoming convexly raised toward the apex; primary lateral veins 12-18 per side, departing midrib at 40-60° angle, straight to near the margin, then arcuate and joining the margin, convexly raised above and below (more so below); tertiary veins obscure above, weakly visible below; collective vein arising from about the middle of the blade or absent, weakly sunken above, raised below, 5-12 mm from margin. INFLORESCENCES erect to spreading, shorter than leaves; peduncle 20-43 cm long, 5-6 mm diam., 4-7 x as long as petiole, medium green, terete; spathe spreading to reflexed, subcoriaceous, green, sometimes tinged with maroon, linear-lanceolate to oblong-ovate, 4.5-7.5 cm long, 0.8-2.5 cm wide, inserted at 30-90° angle on peduncle, abruptly acuminate at apex (the acumen inrolled), obtuse to rounded at base; spadix green to white, becoming pinkish to orange to tan to reddish violet, subcylindroid, prominently curved, 5.2-9 cm long, 0.8- 1.5 cm diam.; flowers 4-lobed, 2-3.4 mm in both directions, the sides weakly to jaggedly sigmoid; 9-15 flowers visible in principal spiral, 12-16 in alternate spiral; tepals matte, greenish white turning pinkish tan; lateral tepals 1.1-1.3 mm wide, the inner margins broadly convex, turned up against pistil, the outer margins 3-4-sided; pistils early emergent, exserted to 2.2 mm, sharply pointed, pale green to white; stigma ellipsoid to circular, 0.5-0.7 mm long, becoming brushlike; stamens emerging slowly from the base, held above then retracting to surface of the tepals; filaments fleshy, colorless, 0.5-1 mm long, 0.6 mm wide; anthers white, 0.7-1 mm long, 0.7-1 mm wide; thecae narrowly ovoid, slightly divaricate; pollen white. INFRUCTESCENCE pendent; spadix to 13 cm long; berries greenish white, reddish to purplish at apex, ovoid, narrowly acute to prominently beaked at apex, ca. 10 mm long, 5 mm diam.; mesocarp clear, juicy; seeds 2 per berry, white to greenish white, oblong-ellipsoid, 3-3.4 mm long, 2 mm diam., 1.5 mm thick, enveloped by gelatinous, transparent substance extending ca. 1 mm beyond seed on both ends.
