LEAVES spreading; petioles 22 cm long, 6-8 mm diam., apparently flattened adaxially, with sharply raised margins; geniculum slightly darker and scarcely thicker than petiole, 1 cm long; sheath 3 cm long; blades chartaceous (probably young), broadly oblanceolate, shortly acuminate at apex, long-attenuate at base, 95.5 cm long, 27 cm wide, broadest in the upper third, the margins slightly sinuate; both surfaces nearly matte, gray-green; midrib weakly and convexly raised toward the base, more prominently raised toward the apex above, prominently convex below; primary lateral veins ca. 27 per side, departing midrib at 40-50° angle, straight to the collective vein, convexly raised above, less conspicuously so below; interprimary veins absent except near the apex, almost as conspicuous as primary lateral veins; tertiary veins obscure above, weakly visible below; reticulate veins not visible; collective vein arising from near the base, as conspicuous as larger tertiary veins, 2-8 mm from margin. INFLORESCENCES spreading; peduncle 24 cm long, 2 mm diam., 1.1 x as long as petiole, green, terete; spathe erect-ascending, chartaceous, green with numerous, conspicuous raphide cells, oblong-elliptic, 9-10 cm long, 1.3-1.5 cm wide, broadest at or near the middle, acuminate-caudate at apex (the acumen 10 mm long), obtuse-rounded at base; stipe 2.5-3 cm long; spadix purplish brown, cylindroid, moderately curved, semi-erect, held at ca. 30-40° angle from peduncle, 6.5-10 cm long, 4 mm diam. throughout or 3 mm diam. near apex; flowers square, 1.2-2 mm long, 1.5-2 mm wide, the sides straight to smoothly or jaggedly sigmoid; 3-5 flowers visible in principal spiral, 5-8 in alternate spiral; tepals very weakly papillate; lateral tepals 0.9-1.1 mm wide, the inner margins rounded, weakly erose, the outer margins 3-sided; pistils not visible; stamens k erect; filaments exserted 0.2-0.4 mm; anthers brownish yellow, 0.5-0.6 mm long, 0.2-0.4 mm wide; thecae oblong-ellipsoid, not divaricate.
