LEAVES spreading; petioles 2-4.5 cm long, 4-5 mm diam., erect-spreading to spreading, quadrangular to trapezoidal, sometimes subterete, with a medial rib and the margins prominently raised adaxially, sharply 3- 5-ribbed abaxially, the surface slightly pale-speckled; geniculum becoming reddish tinged, 0.4-0.7 cm long; blades subcoriaceous to moderately coriaceous, oblanceolate to oblanceolate-elliptic, obtuse, minutely apiculate at apex, obtuse to rounded at base, (14)18-50 cm long, 5.5-16.5 cm wide, usually broadest above the middle, the margins sometimes undulate; upper surface matte-velvety, moderately quilted, medium green, lower surface velvety with conspicuous crystalline cells, slightly paler and often tinged with red; both surfaces drying brown to grayish brown; midrib prominently acute at base, becoming narrowly raised toward the apex above, prominently acute and tinged with reddish below; primary lateral veins 6-1 3 per side, departing midrib at 50-70º angle, straight, flat to weakly raised above, weakly raised and darker than surface and tinged with red below, drying slightly raised above and below; interprimary veins less prominent than primary lateral veins, darker than surface below; tertiary veins slightly darker than surface below, drying weakly raised; reticulate veins obscure; collective vein arising from near the base or in upper third of blade, weakly sunken to flat above, weakly raised and darker than surface below, equally as prominent as primary lateral veins, 4-10 mm from margin. INFLORESCENCES erect; peduncle 2.5-9 cm long, 2-3 mm diam., 1.2-3 x as long as petioles, green faintly tinged purplish, terete with obscure ridge; spathe erect, subcoriaceous, dark purple to purplish violet (B & K red-purple 2/5), ovate-elliptic, navicular, 2.3-4.7 cm long, 1-2 cm wide, broadest in the lower third, cuspidate-acuminate at apex, acute and weakly decurrent at base; spadix reddish (B & K red 7/ 10) to faintly purplish violet or grayish purple, very short, cylindroid, erect, 1.7-4.7 cm long, 2-6 mm diam.; flowers rhombic and weakly 4-lobed, 1- 1.5 mm long, 1.5-1.7 mm wide, the sides ± straight parallel to spiral, jaggedly sigmoid perpendicular to spiral; 8-9(14) flowers visible in principal spiral, 17-21 in alternate spiral; tepals matte, densely and minutely papillate; lateral tepals 0.5-0.9 mm wide, the inner margins rounded to bluntly 3-sided, the outer margins 2-3-sided to shield-shaped and 4-sided; pistils raised, purple, much darker than the tepals; stigma slitlike, 0.2-0.3 mm long; stamens emerging from near the middle, lateral stamens emerging to % the distance to the apex before alternates emerge at lower 95 of spadix; anthers white, 0.4-0.5 mm long, 0.4-0.5 mm wide, contiguous at the surface of the tepals; thecae narrowly ovoid, conspicuously divaricate; pollen yellow, fading to white. INFRUCTESCENCE with berries scattered throughout; berries obovoid, magenta, rounded at apex.
