Leaf solitary; petiole dull or moderately glossy, mid- or dark green with several ± oval or irregular, whitish spots, with or without numerous small, white dots in between, 30–60cm, near base 1–2cm in diam., glabrous; leaf blade moderately or highly dissected, 30–100cm in diam.; rachises narrowly winged; leaflets abaxially pale green, adaxially mid- or dark green, dull or glossy, margin at first reddish pink, later usually turning green or whitish, elliptic-ovate, elliptic, or lanceolate, 4–26 × 1.5–5.5cm, apex acuminate or long acuminate; major veins strongly impressed. Inflorescence solitary, shortly pedunculate; peduncle colored as petiole, 4–20 × 0.8–1.5cm, lengthening in fruit. Spathe strongly convolute at base, outside glossy pale green, with or without a purplish flush, with or without a few small, paler spots; inside dark maroon, near constriction dirty whitish or greenish purple, campanulate, constricted between base and limb, broadly triangular-ovate, 9–25 × 8–23cm, thickly walled, apex acute or obtuse; limb horizontal, irregularly wavy, outside pale green, with a variable, pinkish purplish hue, maroon near margin, inside dark maroon, dull or glossy, near margin greenish or pale purplish, base within densely covered with large, irregular verrucae; venation strongly impressed. Spadix producing a smell of decaying meat or cow dung at female anthesis, sessile, longer than spathe, 20–52cm, female and male zones contiguous or separated by a short (ca. 0.5cm) (partly) sterile zone; female zone cylindric or slightly conic, 1.5–4cm, 2–3cm in diam. (including styles), flowers congested or all or partly ± remote; ovary: base or larger part greenish, rest dark purple, depressed, orbicular or suborbicular in cross section, 1.5–3mm high, 2–3(–4.5)mm in diam., 2-loculed, with 1 basal ovule per locule; funicle long, strongly coiled; style brownish purple or blackish, 2–3mm, slender, 0.8–1.2(–1.5)mm in diam.; stigma grayish purple, large, orbicular or oval in cross section, 0.8–1.5mm high, ca. 2mm in diam., 2- or 3(or 4)-lobed, densely scabrous-papillate; lobes conic, obtuse or subacute; sterile zone with variously transformed male flowers (staminodes), sometimes intermixed with a few sterile remnants of bisexual flowers, often accompanied by all possible transitional stages from adjacent zones; appendix pale or dark brown, narrowly fusiform, 15–42cm, 1.4–3cm in diam. near base, 1.8–4cm in diam. ca. 1/3 from base, oval in cross section, thinly walled and hollow after anthesis, apex ± obtuse or acute, with regular or irregular, shallow, strongly wrinkled and/or with elongate depressions, these in basal half of appendix with or without a short, pale or dark purplish or whitish hair (0.5–2.5mm); sterile flowers (when present) between male and female zone either pale green or purple, to 5mm, hairlike, or reduced bisexual flowers, these consisting of a reduced pistil surrounded by several stamens; male zone ± obconic, 1.5–4.5cm, 0.9–1.9cm in diam. at base, 1.5–3.5cm in diam. at apex, flowers congested or proximal ones distant, free or in distal part fused into low-angled spirals; male flowers consisting of (2 or)3–6 stamens; stamens ivory-white, oval in cross section, ca. 2 × 1.8mm; filaments ca. 1 mm, basally connate; anthers ca. 1 mm, truncate or rostrate (elongation of connective); connective minutely verrucate, after anthesis more strongly rostrate by differential shrinking of lateral sides of anthers; pores apical, elongate prior to anthesis, oval at anthesis, opening by deepening of lower margin, after anthesis ± laterally displaced. Berries blue or violet, elliptic.
