    General Description
    Epiphytic, occasionally terrestrial; stem 10-75 cm long, 2.5-6 cm diam.; leaf scars 1-1.5 cm high, 2-3.5 cm wide; roots few, descending, greenish, pubescent, moderately thick and short, slightly tapered, 3-7 mm diam.; cataphylls subcoriaceous, lanceolate, 16-35 cm long, rounded to emarginated at apex with subapical apiculum ca. 5 mm long, green, drying tan (B & K yellow-red 9/10), persisting semi-intact, eventually as a reticulum of fibers. LEAVES erect to spreading; petioles 18-100 cm long, 7-14 mm diam., bluntly to sharply quadrangular to D-shaped or subterete, prominently to weakly sulcate or flattened adaxially, the margins flat or raised, rounded abaxially, the surface pale-speckled; geniculum thicker and paler than petiole, becoming fissured transversely with age, 1.5-5 cm long; blades moderately to thickly coriaceous, triangular to ovate-triangular, ovate-elliptic, acute to acuminate at apex (the acumen weakly apiculate), subcordate to cordate at base, sometimes decurrent on petiole, 27-98 cm long, 14.5-46 cm wide, broadest in the lower fourth of the blade, the margins broadly undulate; anterior lobe 25.5-90 cm long, the posterior lobes 4-19 cm long, directed downward and sometimes inward or outward; sinus arcuate with blade decurrent on petiole, to spathulate; upper surface matte to semiglossy, dark green, lower surface semiglossy, slightly paler; midrib bluntly angular-raised, becoming acutely to obtusely raised, and then weakly sunken at apex above, prominently and convexly raised below, paler than surface above and below; basal veins 3-6 pairs, often free to base, 2nd and 5th sometimes coalesced 1.5-2 cm, convexly raised above and below (less so below); primary lateral veins 19-25 per side, departing midrib at 50-60° angle, straight or weakly arcuate to the collective vein, prominently to weakly convexly raised above (more so below), paler than surface; interprimary veins sometimes present; tertiary veins obscure to weakly visible above, flat and darker than surface below; collective vein arising from one of the lowermost primary lateral veins or 1st to 2nd basal vein, weakly sunken above, weakly raised and darker than surface below, 1-5 mm from margin. INFLORESCENCES erect to spreading; peduncle 10-35 cm long, 8-10 mm diam., 0.2-0.7 x as long as petiole, green, terete; spathe reflexed, sometimes recurled, coriaceous to subcoriaceous, green to green heavily tinged with purple-violet to purplish or maroon, lanceolate to lanceolate-elliptic, 10-33 cm long, 2.5-5.5 cm wide, broadest just above the base, inserted at 30° angle on peduncle, long-acuminate at apex (the acumen inrolled), rounded to cordate at base; spadix green to purple to maroon, slightly tapered, (6)18-28 cm long, 1-2 cm diam. near base, 8-10 mm diam. near apex; flowers rhombic to weakly 4-lobed, 2.2-3.2 mm long, 2.0-3.1 mm wide, the sides weakly to jaggedly sigmoid; 10-15 flowers visible in principal spiral, 8-20 in alternate spiral; tepals matte, conspicuously punctate, minutely papillate; lateral tepals 0.8-1.6 mm wide, the inner margins broadly convex to concave when dried, the outer margins straight; pistils not emergent except when dried, green tinged with violet-purple; stigma linear, slitlike, 0.5-1 mm long; stamens emerging from the base, lateral stamens followed by alternates in rapid succession, the laterals preceding the alternates by 5-8 spirals, the 3rd stamen preceding the 4th by 6-8 spirals, held over and obscuring pistil; filaments red-violet, 1.4-1.6 mm long; anthers yellow, 0.4-0.7 mm long, 0.5-0.9 mm wide; thecae narrowly oblong to ovoid-oblong, weakly or not at all divaricate; pollen orange fading to tan or white. INFRUCTESCENCE spreading to pendent; spadix to 50 cm long, to 5 cm diam.; berries orange, oblong-ellipsoid to oblong-ovoid, acute at apex, the tip relatively blunt, to 14 mm long, 3.5 mm diam.; mesocarp with linear to punctiform raphide cells; seeds 2 per berry, oblong-ellipsoid to ellipsoid, somewhat flattened, 4.5-5 mm long, 2.7-3.2 mm diam., 1-1.5 mm thick, with a thin appendage at apex only.
