SUMMARY
Terrestrial or epiphytic; stem to ca. 30 cm long, 3-5(6) cm diam.; roots dense, ascending, grayish white to pale green, soft, fuzzy, heavily woolly-pubescent, short, tapered, less than 10 cm long, 3-6 mm diam.; cataphylls subcoriaceous, lanceolate to broadly lanceolate, 3-12 cm long, acute to prominently emarginate at apex, green tinged with red, drying tan to reddish brown, persisting a: a reticulum of fibers. LEAVES semi-erect to spreading, occasionally pendent; petioles 4-26(63) cm long, 4-13 mm diam., sharply D-shaped or C-shaped to ± quadrangular, flattened to sulcate, often with a medial rib adaxially, the margins acutely raised, rounded to 3-5(8)-ribbed abaxially, the surface short-lineate, sometimes pinkish at base; geniculum slightly paler and thicker than petiole, becoming minutely fissured and scurfy adaxially, 1-3.5 cm long; sheath 3-7 cm long; blades moderately coriaceous, mostly oblanceolate, sometimes elliptic or oblong-oblanceolate, mostly rounded or rounded-emarginate on larger leaves, acute to slightly acuminate on smaller leaves at apex (the acumen inrolled, apiculate, sometimes inequilateral, downturned), mostly attenuate or acute (rarely rounded to obtuse) at base, 30-126 cm long, (8)15-47 cm wide, broadest in upper third, the margins slightly to moderately undulate; upper surface glossy to semiglossy or weakly glossy, medium green or yellow- green, lower surface semiglossy or occasionally matte, slightly paler, sometimes weakly to conspicuously whitish glaucescent; midrib flat at base, becoming obtusely to acutely raised toward the apex above, prominently obtuse-raised to 3-6-ribbed at base, becoming prominently convex toward the apex below, paler than surface above and below; primary lateral veins (7)9-18 per side, departing midrib at (30)50-70(80)° angle, weakly arcuate-ascending to the margin, sometimes appearing sinuate, convexly raised above, prominently convexly raised below, paler than surface; interprimary veins few, scarcely visible, sunken above, weakly raised below; tertiary veins weakly sunken or weakly raised above, prominently raised below; collective vein arising from near the apex occasionally in the lower third (especially in smaller plants), sunken above, raised below, 3-9 mm from margin. INFLORESCENCES semi-erect to spreading or pendent, shorter than, or almost equalling leaves; peduncle 30-60(98) cm long, 3-10 mm diam. 2-7 x as long as petioles, green weakly tinged with red, pale short-lineate, terete to subterete, occasionally ribbed abaxially; spathe spreading to reflexed, sometimes twisted, occasionally with prominently revolute margins, subcoriaceous, matte above and below, green to green heavily tinged with red or purple-violet (especially on adaxial surface), oblong-lanceolate to oblong-triangular, (6)l0- 32(55) cm long, (1)2-3.5(4.0) cm wide, broadest near the base, inserted at 20-35° angle on peduncle, long-acuminate to abruptly short-acuminate at apex (the acumen often inrolled, 15-20 mm long), acute or decurrent to 6.5 cm at base; stipe rarely to 14 mm; spadix glaucous, bluish green, sometimes weakly tinged with purple or yellow, very long-tapered, ± erect to pendent and curved upward, (7.5)14-33 cm long, 5-12 mm diam. near base, 3-4 mm diam. near apex, broadest at the base; flowers rhombic, (1.6)1.8-3 mm long, (1)1.4-2.6 mm wide, the sides straight to jaggedly sigmoid; (5)6-9 flowers visible in principal spiral, 8-13 in alternate spiral; tepals glaucous, matte, minutely papillate, with a few scattered droplets, lateral tepals 1-1.6 mm wide, the inner margins broadly convex to straight, the outer margins ± straight or bluntly angled to obtusely 3-sided; pistils emergent, papillate, matte, squarish, pale green; stigma ellipsoid becoming circular, 0.4-0.6 mm long; stamens emerging rapidly in a regular and complete sequence over a 5-6-day period, the laterals preceding the alternates by (3)l0- 14 spirals, the 3rd stamen preceding the 4th by 1-3 spirals, inclined over and obscuring pistil; anthers pale yellow, 0.2-0.8 (dried) to 1 (fresh) mm long, 0.4-0.9 mm wide when fresh; thecae oblong, not divaricate; pollen pale yellow fading to cream, sweetly scented like rotting fruit. INFRUCTESCENCE with spathe persisting; spadix 12-53 cm long, 1.5- 3.5 cm diam.; berries reddish purple, obovoid to oblong, 7-1 2 mm long, 4-5.5 mm diam.; pericarp thin, with raphide cells; mesocarp gelatinous; seeds 1-2 per berry, oblong, 4-5 mm long, 1.6-2.2 mm diam., 1-1.2 mm thick, with a mucilaginous appendage.
