    General Description

    Medium-sized, robust aseasonally dormant geophytic herb to 90 cm. Tuber depressed globose, not offsetting, with irregular raised areas, to 32 cm diam. × 15 cm high, surface with a grey, corky layer. Leaf solitary; petiole short, to 50 × 5 cm diam., uniformly green, very turgid; lamina to 188 cm diam., highly dissected, rachises naked; leaflets elliptic-lanceolate, to 35 ×11 cm, those on the most proximal parts of the rachises petiolulate, upper surface mid-green, slightly glossy or dull, slightly coriaceous. Inflorescence solitary, rarely two together, short pedunculate; cataphylls off-white; peduncle 8-13 ×1- 2.2 cm diam., entirely subterranean, white with a faint greenish flush, smooth, very tightly enveloped by the cataphylls; spathe erect, suborbicular, often broader than long, 10-13.5 × 11.5-16 cm diam., limb obliquely spreading at female anthesis, erect at male anthesis, lower part tubular, strongly convolute, largely hidden in cataphylls, spathe exterior off-white, occasionally flushed pale reddish purple on the inside limb margins, interior with base reddish purple, and with scattered small warts, or coarsely grooved, with grooves distinctly verruculate. Spadix longer than spathe, stipitate, 13.5-21 cm long; stipe massive, oblique, off-white, 0.6-1 × 1.6 cm diam. (base); female flower zone 1.5-2.5 cm × 1.5-2.3 cm diam., slightly conic, flowers in vertically separate sinuous chains; male flower zone conic, 3-4.5 × 1.1-2.2 cm diam., flowers arranged as female flowers but chains closer together, or partly or entirely fused vertically, sometimes forming vertical chains; appendix fusiform, 8-14 × 1.2-2.8 cm diam., slightly laterally compressed, subacute, yellowish white, surface rugulose and with narrow, shallow grooves, producing a strong smell of fried fish and oozing out droplets at female anthesis. Pistil (female flower) with an ovate or slightly depressed ovary, 2-3 mm diam. × 2.5-3 mm high, base off-white, top dirty reddish brown, unilocular, one basal ovule; style excentrically placed, consisting of three acute branches, two acroscopic small ones and one basiscopic longer one, pale dirty reddish brown, ca 1.5 mm diam. × 0.3-0.8 mm long; stigma thin, ca 1.5 mm diam. × ca 0.5 mm high, irregularly, shallowly lobed-sinusoid, surface very pale dirty brow nish, verruculate. Male flo wer consisting of ca 3 stamens but pattern often obscured by lateral and vertical fusion of flowers; stamens ca 1 mm high, × ca 1-2 mm diam., often fused with adja cent stamens; filaments ca 0.5 mm long, entirely connate; anthers ca 0.5 mm long, truncate, often entirely connate, ivory-white; pores apical, rounded, oval or variously elongate, often confluent with adjacent pores in various ways. Fruit a very large, elongate, slightly angulate berry, up to 4 × 2 cm, ripening red, 1-seeded. Seeds elongate-oblongo-conical, ca 3 cm × 1.2 cm diam. at the point of germination, 0.7 at the opposite end, skin brownish.
