LEAVES spreading-erect; petioles 10-33 cm long, 3-8 mm diam., terete to subterete, sometimes obtusely flattened adaxially, rounded abaxially; geniculum obscurely flattened, scarcely darker than petiole, 0.6-2 cm long; subcoriaceous, narrowly to broadly elliptic, occasionally oblanceolate, gradually acuminate at apex, slightly attenuate to narrowly acute to obtuse to subtruncate at base, 20-56 cm long, 4-15 cm wide, broadest at or near the middle; upper surface matte to semiglossy, dark to medium green, lower surface glossy to semiglossy, much paler; both surfaces drying matte to semiglossy, bright green to yellowish; midrib round-raised at base, becoming very narrowly and sharply raised (knife-like) toward the apex above, prominently and convexly raised with a sharp rib below; primary lateral veins 12-35 per side, departing midrib at 45-55° angle, ± straight to the collective vein, prominently and sharply raised above, flat to raised below, very sharply raised above when dried; interprimary veins drying almost as conspicuous as primary lateral veins, sharply raised above; tertiary veins obscure, drying prominulous; collective vein arising from the base, scarcely visible above, flat below, less prominent than primary lateral veins when dried, 3-1l mm from margin. INFLORESCENCES spreading: erect, shorter than leaves; peduncle 6.2-29(38) cm long, 2-6 mm diam., (0.9)1.9-2.7 x as long as petiole, pale green, tinged with violet-purple, subterete to angulate; spathe spreading to reflexed and recurled, subcoriaceous, green to green tinged with purple at margins and on veins, oblong-lanceolate, 2.5-7 cm long, 7-10 mm wide, broadest near the base. inserted at 65° angle on peduncle, acute to shortly acuminate at apex (the acumen apiculate), acute at base; stipe 7-10 mm long in front, 3-6 mm long in back; spadix maroon to purple, becoming brown (B & K red-purple 2/7.5), cylindroid, sometimes slightly tapered at apex, 3-8 cm long, 3-6 mm diam. midway; flowers 4-lobed, 2.1-2.4 mm in both directions. the sides jaggedly sigmoid; 3-5 flowers visible in principal spiral, 6-8 in alternate spiral; tepals matte, weakly papillate, with droplets; lateral tepals 1-1.3 mm wide, the inner margins straight to convex, slightly turned up against the pistil, the outer margins irregularly 3-4-sided; pistils raised, green; stigma ellipsoid; stamens emerging in a scattered pattern from the base of the spadix; filaments transparent, thick, exserted, soon retracting, holding anthers at level of the tepals, ca. 0.3 mm long, 0.4 mm wide; anthers yellowish heavily tinged with maroon, 0.6 mm long, 0.9 mm wide, inclined over and obscuring the pistil; thecae oblong, not divaricate; pollen orange, fading to tan. INFRUCTESCENCE with spathe persisting; spadix 6 cm long, 1.3 cm diam.; berries purple, obovoid, truncate at base, rounded somewhat mammilliform at apex, 6-6.8 mm long, 3.7-4.5 mm seeds 2 per berry, brownish, oblong, flattened, rounded at both ends, 3.2-3.5 mm long, 2.2-2.5 mm diam., 1.5-1.7 mm thick, enveloped by gelatinous, translucent, amber substance.
