    General Description
    Terrestrial, less than 1 m tall; stems ca. 4 cm diam.; roots 3 mm diam.; tan, smooth to woolly pubescent (dry); cataphylls ca. 8 cm long, drying tan to reddish-brown, weathering to moderately thin fibers. LEAVES with petioles 29-18 cm long, 6-8 mm diam., sharply and broadly sulcate adaxially; the geniculum 1-1.5 cm long; blades broadly ovate to ovate-triangular, 30-57 cm long, 22-56 cm wide, broadest at base, acute to narrowly rounded and apiculate at apex, deeply lobed at base, the margin sinuate and undulate; anterior lobe 25-45 cm long; posterior lobes 11.5-25 cm long from apex of sinus to the outermost point; the sinus arcuate or arcuate with petiole decurrent; upper surface semiglossy, lower surface matte, often whitish with glistening translucent circular cells scattered in the epidermis (visible at high magnification on dried leaves); midrib convexly raised above; the basal veins 5-9, all except the first and second (third) coalesced 5-11.5 cm, raised on both surfaces, drying darker than the surface; posterior ribs broadly arcuate, naked most their length; primary lateral veins 5-9 per side, almost straight or gradually curved upward, arcuate-ascending near margin and joining margin, raised on both surfaces; collective vein arising from one of the lowermost primary lateral veins (rarely as low as the first basal vein), 3-7 mm from margin, weakly raised on both surfaces. INFLORESCENCE spreading-pendent (?); peduncle 30-43 cm long, 3-5 mm diam., terete, shorter to longer than petioles; spathe subcoriaceous, green, lanceolate to ovate-lanceolate, 10-13 cm long, 1.5-3 cm wide, broadest just above base, narrowly acuminate at apex, rounded to subcordate at base, inserted at ca. 45° angle on peduncle; the stipe 3-25 mm long in back, 1-15 mm long in front, 3-4 mm diam.; the spadix violet-purple, 6.5-15 cm long, 6-9 mm diam. at base, 4-5 mm diam. at apex, sometimes curved; the flowers rhombic, 3.6-4.7 mm long, 2.6-3.9 mm wide (dry), the sides scarcely to jaggedly sigmoid; 6-8 flowers visible in the principal spiral, 4-6 flowers visible in the alternate spiral; tepals matte, very minutely papillate, lateral le-pals 2.7-3 mm wide, the inner margin broadly rounded; pistils not emergent; stigma oblong, 1 mm long; stamens emerging from the base in a moderately slow progression; the anthers held in a close cluster completely obscuring the pistil, ca. 1 mm long, ca. 1.4 mm wide; thecae narrowly ovate, scarcely divaricate; pollen not seen. INFRUCTESCENCE pendent, berries often developing only in the basal one half or one third; spathe persistent: spadix ca. 20 cm long, 3 cm diam.; berries obovoid, truncate to broadly rounded and scurfy, 10-13 mm long, 9-10 mm diam.; pericarp moderately thick, leathery at apex, small raphide cells, very dense in lower three quarters of berry; seeds 1-2, ± lens-shaped, brown, considerably flattened, raphide cells sparse and minute, 9-13 mm long, 7-9 mm wide, 3-4 mm thick, weakly depressed at apex, with a sticky, gelatinous appendage sometimes as large as seed.
