General Description
Terrestrial or occasionally epiphytic; stem to ca. 20 cm long; internodes short, 1-7 cm diam.; roots dense, spreading, the uppermost ones ascending, thick and blunt at apex, 5-12 cm long, 1-5 mm diam.; cataphylls subcoriaceous or fleshy, 2.5-12 cm long, acute at apex, tinged with red, persisting as coarse linear fibers at base. LEAVES erect to arching when large; petioles (3)6-30(42) cm long, 8-15 mm diam., C-shaped or sharply D-shaped, sulcate to flattened with the margins sometimes weakly raised and a broad medial rib occasionally present adaxially, rounded abaxially, sometimes 1-2-ribbed; geniculum slightly thicker than petiole, 0.5-1 cm long; blades coriaceous, oblanceolate to obovate, rarely broadly elliptic, acute to obtuse to rounded at apex, long-attenuate to acute or obtuse at base, 30-80(140) cm long, 20-40(65) cm wide, broadest above the middle, the margins undulate; upper surface semiglossy, dark green, lower surface semiglossy to matte, paler and with pustules and glandular-punctations; midrib flat to broadly sulcate at base, sometimes with faint medial rib, becoming prominently convex toward the apex above, higher than broad at base, becoming convexly raised toward apex below; primary lateral veins 6-9(13) per side, departing midib at 40-60° angle, ascending and weakly arcuate to the collective vein, loop-connecting in the upper ?, raised in grooves above, raised and paler than surface below; tertiary veins sunken above, raised below; collective vein arising in the upper ? of blade, almost as prominent as primary lateral veins, or often absent, 5-10 mm from margin. INFLORESCENCES erect-spreading, nearly as long as or longer than leaves; peduncle 24-96 cm long, 4-10 mm diam., (1.5)4-5(7) x as long as petiole, green tinged with maroon or purple, terete; spathe spreading-reflexed, sometimes inrolled, coiling-recurled or reflexed, subcoriaceous, pale to medium green, sometimes suffused with purple, oblong-lanceolate, (4)8-18(24) cm long, 1-3.5 cm wide, broadest near the base, acute to shortly acuminate at apex (the acumen ca. 10 mm long), obtusely clasping at base; spadix greenish when young, becoming reddish to purple or purple-brown at anthesis, sessile or subsessile, ± cylindroid, shortly to gradually tapered at apex, erect, 5-33 cm long, ca. 5-7 mm diam. near base, 2-3 mm diam. near apex; flowers (dried) rhombic, (1.6)2.8-3.4 mm long, (1)1.8-2.8 mm wide, the sides straight parallel to spiral, smoothly and weakly sigmoid perpendicular to spiral; 3-7(9) flowers visible in principal spiral, 4-6 in alternate spiral; tepals minutely papillate, sometimes whitish muricate, matte; lateral tepals 1.4-2 mm wide, the outer margins 2-sided, the inner margins broadly convex; pistils squarish, weakly emergent; stigma rectangular, 0.6 mm long, appearing papillate; stamens emerging in a regular sequence from the base, the laterals preceding the alternates by 7- 10 spirals, the 3rd stamen preceding the 4th by 6-8 spirals, arranged in a circle, inclined over and obscuring the pistil; anthers yellow, 0.4-0.6 mm long, 0.5-0.8 mm wide; thecae oblong, 0.2-0.3 mm wide, slightly divaricate; pollen white. INFRUCTESCENCE with spathe withered, eventually deciduous; spadix 8-35 cm long, to 2 cm diam., bearing berries in the basal portion only, the apical portion sometimes weathering away; berries reddish purple, white in basal ?, obovoid, 6-10 mm long, 5-8mm diam.; pericarp thickened, with raphide cells; seeds 1 or 2 per berry, reddish violet, ellipsoid, weakly flattened, 3-6 mm long, 2-5 mm diam., 1-2 mm thick, attached to carpel wall at radicle end and by a thick strand of fibers.
