    General Description
    Terrestrial or epiphytic; stem to 30 cm long, 2-3.5 cm diam.; roots dense, descending, white, fuzzy, short, ca. 3 mm diam.; cataphylls subcoriaceous, lanceolate to hook-shaped, 2-ribbed, 5-11.5 cm long, acute to acuminate at apex, drying reddish brown, persisting semi-intact, eventually as a reticulum of fibers. LEAVES erect-spreading; petioles 8-48 cm long, 4-12 mm diam., sharply D-shaped to C-shaped, flattened to sulcate and with a medial rib adaxially, the margins sharply to bluntly raised or bluntly acute, rounded to 3-5-ribbed abaxially, the surface pale-short-lineate, sometimes tinged with purple; geniculum paler and thicker than petiole, becoming calloused and minutely transverse-fissured with age, 1-2 cm long; sheath 3-10 cm long; blades subcoriaceous, broadly oblanceolate to obovate-elliptic to broadly elliptic, acute to acuminate at apex, acute to attenuate at base, (26)50-125 cm long, 10.5-36.5 cm wide, broadest at or above the middle, the margins undulate, concave toward base; upper surface semiglossy, dark to medium green, lower surface semiglossy to weakly glossy, moderately paler; midrib above flat to bluntly raised at base, becoming sharply acute toward the apex and paler than surface, below bluntly acute at base, becoming broadly convex to acutely raised toward the apex; primary lateral veins 6-14 per side, departing midrib at 70-90° angle, retrorse to 130° toward the base, ± straight to arcuate ascending to the margin, raised above, bluntly convex below; interprimary veins not visible; tertiary veins weakly raised above, flat and darker than surface below; collective vein arising from near the base or near the apex, prominulous, 2-10 mm from margin. INFLORESCENCES erect to spreading; peduncle (10)30-98 cm long, 2-9 mm diam., 1.2-4.6 x as long as petiole, green to reddish green, terete; spathe reflexed-spreading, sometimes recurled, subcoriaceous, sometimes reddish, usually green tinged with red or purple (B & K yellow 5/7.5), broadly lanceolate, (3.5)8-12(18) cm long, 1.3-2.5 cm wide, broadest near the base, inserted at 40-60° angle on peduncle, acute to acuminate at apex (the acumen apiculate), acute to rounded at base; spadix olive-green to gray-green to brownish to violet-purple (B & K red- & & purple 2/2.5), sometimes weakly glaucous, slightly tapered, sessile or stipitate to 2 cm, erect, straight to curved, held at ca. 180° ang-le from peduncle, 5-13(28) cm long, 4-7 mm diam. midway, 2-4 mm diam. near apex; flowers rhombic to 4-lobed, 2-2.3 mm long, 2 mm wide, the sides smoothly sigmoid to jagged; 7-10 flowers visible in principal spiral, 5-7 in alternate spiral; tepals minutely papillate, matte, white-pustulate; lateral tepals 0.5- 0.6 mm wide, the outer margins 3-4-sided, the inner margins weakly curved; pistils papillate, minutely granulose, raised, red-violet to maroon; stigma linear, 0.4 mm long; stamens emerging in a -regular sequence, the laterals preceding the alternates by 4-14 spirals, the 3rd stamen preceding the 4th by 5-7 spirals, arranged in a circle around the pistil; anthers pinkish to reddish brown, 0.5- 0.7 mm long, 0.5-0.7 mm wide, thecae divaricate; pollen yellow fading to white, yeasty-scented. INFRUCTESCENCE with spathe persisting; spadix 9-17 cm long; berries maroon to deep red-violet (B & K red-purple 2/5), obovoid, flattened to depressed at apex, 6.5-7.5 mm long, 5-6 mm diam.; mesocarp transparent, gelatinous; seeds 2 per berry, white tinged with red-violet at base, 4.5-6 mm long, 2-3.5 mm diam.
