SUMMARY
Epiphytic, rarely terrestrial; stem pendent, 20-30 cm long, 1.5-3.5 cm diam.; leaf scars reported as conspicuous, ca. 2.8 cm wide; roots moderately dense, descending, brown, 6 mm diam.; cataphylls moderately coriaceous, broadly lanceolate, scarcely 1-ribbed, 4-19 cm long, acuminate at apex with subapical apiculum, green, drying brown (B & K yellow-red 9/2.5), persisting as coarse linear fibers, the apex remaining intact. LEAVES spreading-pendent to pendent; petioles 27-65 cm long, 5-10 mrn diam., terete to subterete or thicker than broad, slightly flattened adaxially, rounded abaxially, the surface minutely pale-speckled; geniculum paler and thicker than petiole, 1.5-3.5 cm long; sheath 2.5-12 cm; blades coriaceous to subcoriaceous, oblong to oblanceolate, acuminate at apex, acute to rounded (rarely subcordate) at base, 64-190(207) cm long, 16-32(42.5) cm wide, broadest above the middle, the margins weakly revolute, broadly and weakly undulate; upper surface glossy to semiglossy, light to medium green (B & K yellow-green 5/10), lower surface matte, paler; midrib convexly to obtusely raised, paler than surface above, obtusely angled below; primary lateral veins (8)ll-15 per side, departing midrib at 45° angle, arcuate-ascending to the margin, sunken in shallow grooves above, paler than surface, raised below; interprimary veins few, obscure; tertiary veins obscure above, scarcely raised and darker than surface below; collective vein arising in the lower third to about the middle of the blade, less prominent than primary lateral veins, (4)7-14 mm from margin. INFLORESCENCES erect-spreading; peduncle 35-52 cm long, 0.5-1 cm diam., 0.5-1.7 x as long as petiole, terete; spathe reflexed and twisted, subcoriaceous, pale yellowish green to creamy white, violet at margins and at base (B & K yellow-red 9/10), oblong-lanceolate, (9)20-30(60) cm long, 1.5-4.8 cm wide, broadest just above the base, acuminate at apex (the acumen inrolled), acute at base; stipe 8-12 mm long in front, 2-5 mm long in back; spadix reddish violet to reddish purple (B & K purple 2/7.5 to red-purple 7/5-10), tapered, curved, 19.5-38 cm long, 4-9 mm diam. midway, 2-4 mm diam. near apex; flowers weakly 4-lobed to rhombic, 2.5-3.5 mm long, 1.7-3.3 mm wide, the sides straight to sigmoid; 12-16 flowers visible in principal spiral, 8-27 in alternate spiral; tepals matte and weakly punctate; lateral tepals 1.4-2.2 mm wide, the inner margins broadly rounded to somewhat concave, the outer margins 3-5-sided; pistils glossy, weakly exserted, green; stigma brushlike; stamens emerging irregularly; filaments fleshy, translucent, minutely papillate, exserted 0.5 mm; anthers creamy white to yellow, 0.5 mm long, 0.6-0.7 mm wide, inclined over the pistil; thecae ovoid-ellipsoid to pyriform, weakly divaricate; pollen yellow fading to white. INFRUCTESCENCE pendent to spreading-pendent, sometimes coiled; spathe withered; spadix 27-55 cm long, 1-2 cm diam., with berries scattered throughout; berries lavender, becoming white at maturity, obovoid-oblong, rounded at apex, 10-11 mm long, 5-6 mm diam.; pericarp thickened; mesocarp mealy, white; seeds 1-2 per berry, brown, oblong, (5.5)7.3-7.8 mm long, 2.8-3 mm diam., 1.3 mm thick.
