SUMMARY
Terrestrial; stem short, less than 20 cm long; internodes short, 2.5 cm diam.; cataphylls pale green drying dark brown to 4 cm long, acuminate at apex, persisting semi-intact on upper nodes and as fragments on older stems. LEAVES pendent from sub-erect petioles; petioles 9.7-30.5 cm long, 6-9 mm diam., uniformly medium green, prominently 7-9 ribbed, broadly and sharply flattened-sulcate adaxially, the margins moderately acute, prominently 3-ribbbed abaxially, the ribs at the base of the petioles and on geniculum prominently undulate, sometimes also along the length of the petiole; blades narrowly elliptic-ovate and cordate-sagittate, abruptly acuminate at apex, deeply lobed at base, 20-41 cm long, 15-34.7 cm wide, 1-1.55 times longer than wide (averaging 23.7 X 30.6 cm), 1-2.1 times longer that petioles (averaging 1.6 times longer), glittering light green above (metallic pink or tan when young), paler and matte below (light pink or buff when immature); petiolar plexus prominent, raised on adaxial surface; basal veins 4-7 pairs, the 1st and usually the 2nd, often the 3rd pair free to the base, the (2nd)4th to 5th and higher order usually coalesced (4-)6-10 mm at base, the posterior rib short or inconspicuous, scarcely naked along the margins 0-8(-15 mm); anterior lobe 15.7-30.5 cm long, broadly rounded along margins; posterior lobes 5.5-14 cm long, 4.9-13.5 cm wide, directed toward the base, overlapping and turned upward against each other along their inner margins; sinus 5.5-14 cm deep, narrow to closed with the lobes turned up against each other or up to 3.0 cm wide, primary lateral veins 2-7 pairs, disposed mostly along the midrib from the lower 1/3 to the apex, arising at 45-70° angle, the area between the primary lateral veins moderately quilted; collective veins arising from one of the primary lateral veins in the upper portion of the blade or more frequently from the 1st pair of basal veins; lower surface covered with a dense array of raised whitish punctations, especially near the basal veins. INFLORESCENCE erect; peduncle terete 8-38.5 cm long, 5-6 mm diam.; spathe 5.5-11 cm long, 1.1-2.7 cm wide, usually green or greenish, rarely white, lanceolate, erect-spreading to spreading, slightly curled downward toward the apex, narrowly to abruptly acuminate at apex; spadix 4.5-10.6 cm long, 5-7(-8) mm diam., green to gray-green (rarely pink), shortly cylindroid tapered, sessile or stipitate 3-6(-10) mm, narrowly rounded at apex; flowers 6-7 visible per spiral, 1.9-2.2 mm long, 2.0-2.2 mm wide, tepals with a few scattered pale sub-linear, pale cellular inclusions; lateral tepals 1-1.2 mm wide, outer margins 2-sided.
