    General Description
    Epilithic; stem usually less than 15 cm long, 1-3 cm diam.; leaf scars 0.7 cm high, 1 cm wide; roots dense, ascending to descending, brown, smooth to tomentose, weakly tapered, 3-4 cm long, 3-5 mm diam.; cataphylls subcoriaceous, broadly lanceolate-triangular, (2)4-4.5 cm long, acute at apex, drying dull brown, persisting semi-intact, quickly dilacerating and persisting as fine linear fibers, splitting at apex. LEAVES erect to spreading; petioles 3-8 cm long, (4)6-12 mm diam., broadly and sharply triangular, sometimes sharply D-shaped, flattened, sometimes with a medial rib adaxially, the margins winged and undulate, prominently and sharply angular to rounded abaxially; geniculum scarcely to moderately thicker than petiole, 0.5-1 cm long; sheath 2-3.5 cm long; blades coriaceous to subcoriaceous, broadly oblanceolate-elliptic, acute at apex, obtuse to shallowly cordate at base, 41-72 cm long, (10.5)13-18 cm wide, broadest at or above the middle, the margins sometimes concave toward the base, moderately to strongly undulate; upper surface matte to semiglossy, dark green, lower surface semiglossy, paler; both surfaces strongly bullate and quilted; midrib flat and with a sharp rib at base, becoming acutely raised and higher than broad toward the apex above, acutely raised, higher than broad and 1-ribbed to winged below; primary lateral veins 22-26(35) per side, departing midrib at acute to obtuse angle, spreading retrorsely at 30-70° angle, conspicuously arcuate to the collective vein, narrowly raised in deep grooves above, less so below, knife-edge-like when dried below, less so above; interprimary veins few, almost as conspicuous as primary lateral veins; tertiary veins weakly raised to flat below, weakly visible above and below when dried; reticulate veins obscure to conspicuous when dried, flat; collective vein arising from near the apex, about the middle of the blade or near the base, equally as prominent as major tertiary veins, 2-5 mm from margin. INFLORESCENCES erect; peduncle 15-40 cm long, 3- 7 mm diam., 2.8-8(11) x as long as petiole, olive-green to dark green, terete with a diminishing rib, firm; spathe ascending to reflexed, sometimes recurled, subcoriaceous to coriaceous, olive-green to pale olive-green, tinged with red to uniformly dark green, lanceolate-ovate to oblong-lanceolate to oblong- elliptic, 4.5-9 cm long, 0.7-2.4 cm wide, broadest near the base. inserted at 45-80° angle on peduncle, abruptly acuminate at apex (the acumen tightly inrolled and cuspidate, 2-3 mm long), acute to obtuse to at base, the margins meeting at 80° angle; stipe ca. 6-13(20) mm long in front, 1-6 mm long in back; spadix red-violet to dark red-purple (B & K purple 4/7.5), tapered, erect, somewhat curved, 6-11 cm long, 5-10 mm diam. near base, 2-5 mm diam. near apex, broadest at the base; flowers ± square, 2.0-2.5 mm long when fresh, drying 1.9-2.4 mm long, 2.5-3.7 mm wide when fresh, drying 1.7-1.9 mm wide, the sides straight to smoothly or jaggedly sigmoid; 5-9 flowers visible in principal spiral, 4-14 in alternate spiral; tepals densely and minutely papillate; lateral tepals 1.1-2 mm wide, the inner margins ± straight to broadly convex, weakly erase, the outer margins 2-3-sided; pistils weakly raised, greenish, somewhat papillate; stigma slitlike, becoming broadly ellipsoid to nearly circular, 0.4-0.5 mm long, depressed medially with the margins somewhat raised when fresh, drying slightly sunken and blackish; stamens emerging rapidly in a complete sequence, the laterals preceding the alternates by 6-14 spirals, 3rd preceding 4th by 1-2 spirals, held at the sides of the pistil; anthers yellow, 0.5- 0.9 mm long, 0.7-1.0 mm wide; thecae ovoid-ellipsoid, not divaricate. INFRUCTESCENCE with spathe green, persisting; berries reddish violet, 8 mm long.
