Epiphytic or terrestrial from near the ground; stems 1 m or more long, 0.8-1.3 cm diam., the epidermis tan (closest to B & K Yellow-red 9/5), glossy; internodes 3-7 cm long; leaf scars ca. 1 cm wide; roots elongate, slender, descending; cataphylls subcoriaceous, 7-16 cm long, apiculate at apex, drying tan to light brown, persisting around stem at upper nodes, deciduous in lower portion of stem. LEAVES spreading, usually at apex of stem; petioles terete to weakly flattened adaxially, 13-40 cm long, 3-6 mm diam.; geniculum 1-3 cm long, weakly sulcate; blades ovate to ovate-triangular, moderately thin, long-acuminate at apex, broadly to deeply lobed at base, 16-46 cm long, 9.5-28 cm wide, broadest near the base; anterior lobes 4.5-38 cm long, the margins straight to convex or concave; posterior lobes 4-13 cm (from apex of sinus to outermost tip of lobe); sinus arcuate to parabolic to hippocrepiform, rounded at apex; the surface matte, usually drying conspicuously blackened, midrib acutely raised above, diminished and sunken toward apex, convexly raised below; basal veins 5-7 pairs, the first, sometimes second free, the remainder coalesced 0.7-3 cm, raised on both surfaces; posterior ribs naked, weakly turned up on outer margins; primary lateral veins 5-8 per side, departing the midrib at a 35-45° angle, usually straight, sometimes weakly arched to collective vein, sunken above, raised below; interprimary veins sunken above, prominulous below; secondary veins visible, flat; collective vein arising from one of the lowermost basal veins, loop-connecting with the basal and primary lateral veins, 4-9 mm from the margin, all veins drying darker than surface. INFLORESCENCE spreading; peduncles terete, 9.5-20 cm long, 3-5 mm diam.: spathe subcoriaceous, pale green (B & K Yellow-green 7/10), linear-lanceolate, 6-12 cm long, 0.8-1.5 cm wide, broadest just above base, cuspidate at apex, rounded to subcordate at base, inserted on the peduncle at ca. 30° angle; stipe ca. 3 mm long; spadix yellow-green turning yellow, weakly tapered toward apex, 6.3-14 cm long, 5-11 mm diam. at base, 4-8 mm diam. at apex; flowers 4-lobed (1.8-)2.2-2.7 mm long, (1.8-)2-2.4 mm wide, the sides jaggedly sigmoid, ca. 6 flowers visible in the principal spiral, 8-10 flowers visible in the alternate spiral; tepals semiglossy, minutely and inconspicuously punctate, lateral tepals (0.7-) 1-1.2 mm wide, the inner margin turned up against pistil; pistils scarcely emergent, green, same color as tepals; stigmas scarcely visible; stamens emerging from the base, lateral stamens emerging from base to apex, followed quickly by alternates; anthers white, 0.3-0.5 mm in both directions, held over pistil; thecae ellipsoid, tan; pollen creamy white. INFRUCTESCENCE with berries red, ellipsoid to ovoid, rounded at apex, 5-6.5 mm long, 3-4 mm diam., the mesocarp with linear to punctiform raphide cells in the apical half; seeds 2, broadly ellipsoid, rounded at both ends, 1.7-3 mm long, 2.2-2.5 mm wide, 1.1-1.3 mm thick, the appendage enveloping all of one side of seed and extending to ca. 1 mm beyond the seed on the apical end.
