LEAVES erect-spreading; petioles 20-27 cm long, 7-10 mm diam., quadrangular to bluntly D-shaped, flattened to broadly and shallowly sulcate adaxially, rounded abaxially, surface pale-speckled; geniculum thicker and slightly paler than petiole, becoming fissured transversely with age, 3-4.5 cm long; blades coriaceous, oblong to oblong- oblanceolate or lanceolate, acute at apex (the acumen apiculate), acute and decurrent to rounded at base, 47-69 cm long, 10- 19 cm wide, broadest at or near the middle, the margins broadly undulate; both surfaces matte, dark green above, paler below; midrib flat at base, becoming obtusely angular and narrowly raised at apex above, bluntly 2-ribbed and higher than broad at base, becoming prominently and convexly raised toward the apex below; primary lateral veins numerous, departing midrib at 60-70º angle,± straight, arcuate near the margin, sunken in grooves above, raised below, paler than surfaces; interprimary veins obscure above, darker than surface below; tertiary veins obscure above, darker than surface below; collective vein arising in the upper third of the blade, weakly sunken above, raised below, less prominent than primary lateral veins, 5-6 mm from margin. INFLORESCENCES spreading, shorter than leaves; peduncle 33-39 cm long, 9-1 2 mm diam., 2 x as long as petiole, subterete; spathe reflexed, coriaceous, dark green (B & K yellow-green 5/10), ovate-lanceolate, 16-17 cm long, ca. 4 cm wide, inserted at 45º angle on peduncle, acuminate at apex, rounded at base; stipe 7-13 mm long in front, ca. 3 mm long in back; spadix pale lavender to violet-purple (B & K purple 6/5 to 5/2.5), tapered, 15-23 cm long, (4)6-12 mm diam. near base, 2-5 mm diam. near apex; flowers rhombic, 3-3.5 rnm long, 3.1-3.6 mm wide, the sides straight to weakly sigmoid; 7-8 flowers visible in principal spiral, 8-1 0 in alternate spiral; tepals matte; lateral tepals 1.5-1.8 mm wide, the inner margins broadly convex; pistils scarcely emergent, green; stigma ellipsoid, ca. 0.6 mm long, droplets appearing for ca. 1 week before stamens emerge; stamens emerging rapidly from near the base or sometimes from near the middle, lateral stamens emerging to midway before alternates appear; anthers yellow-orange, ca. 1 mm long, 1.2 mm wide, inclined over the pistil; thecae oblong-ellipsoid, scarcely divaricate; pollen yellow-orange (B & K yellow-red 8/5). INFRUCTESCENCE pendent; spathe twisted; spadix 24- 26 cm long, 2.3-2.5 cm diam.; berries bright orange, obovoid, flattened at apex, 0.8-15 mm long; pericarp thin, ± transparent; mesocarp fleshy, orange, with minute raphide cells; seeds 1-2 per berry, pale yellow, ovoid, with a somewhat flattened appendage at both ends, enveloped by somewhat dry, sac-like structure .
