    Tuber subglobose to depressed globose, ca. 8 cm in diam., bright orangish brown, offset vegetative propagation unknown. Leaf solitary; petiole 12-15 cm long, 1-1.4 cm in diam., sturdy, smooth, semi-glossy, background colour pale olive green, with numerous small or larger and then confluent, blackish green spots; lamina moderately dissected, anterior segment sometimes undivided, 30--40 cm wide, rachises unwinged; leaflets elliptical, 10-17 cm long, 4-7 cm wide, acute, leathery, upper surface bright pale grey-blue, lower surface bluish green. Inflorescence appearing a while after leaf maturation, longer than leaf; peduncle 35 cm long, 0.7 cm in diam., coloured as petiole but with additional small, scattered white spots; spathe cymbiform, triangular-ovate, slightly hooded, 12 cm long, 6 cm in diam., outside uniformly pale green, after female anthesis changing to whitish green, inside whitish green and at the base a short dark purple zone, base within very shallowly rugulose, apex sharply acute; spadix shorter than spathe, sessile, 8 cm long; female zone cylindric, 6 mm long, 8 mm in diam., flowers congested; male zone cylindric, 5 cm long, 1 cm in diam., flowers distant; appendix stipe 7 mm long, 4 mm in diam. at the middle, appendix conical, 1.7 cm long, 0.9 cm in diam. at the base, apex obtuse, surface deeply corrugated separating rod-like papillae and short sinuous muri, off-white. Ovary depressed, 1.2 mm high, 2.2 mm in diam., off-white; style short and thick, 0.4 mm long, 1 mm in diam., off-white; stigma depressed, 1.5 mm in diam., 0.4 mm high, entire, strongly echinulate, bright pale yellow, unilocular; stamens consisting of 3-4(-5) stamens; stamens 2-2.5 mm long; filaments entirely or basally fused, column 1-1.5 mm long, 0.5-0.8 mm in diam., off-white; anthers free but in the lowermost flowers more or less laterally fused to form synandria, subglobose, ca. 1 mm in diam., off-white. Pollen striate with psi late polar caps.

    Tuber subglobose, depressed globose or short elongate, 2–10 × 2–8 cm. Leaf solitary; petiole 12–15 × 1–1.4 cm, smooth, semiglossy, background colour pale olive-green, with numerous small or larger and then confluent, blackish green spots; leaf blade moderately dissected, anterior segment sometimes undivided, 30–40 cm wide, rachises unwinged; leaflets elliptic, 10–17 × 4–7 cm wide, acute, leathery, adaxially bright pale grey-blue, abaxially bluish green. Inflorescence appearing some time after leaf maturation, longer than leaf; peduncle 35–46 cm × 7–13 mm, appearance as petiole but with additional small, scattered white spots; spathe cymbiform, triangular ovate, slightly hooded, 11–14 × 5–7 cm, exterior uniformly pale green, changing to whitish green after staminate anthesis, interior whitish green with a short dark purple zone at the base, base within very shallowly rugulose, apex sharply acute; spadix shorter than spathe, sessile, 8–10.5 cm long; pistillate flower zone cylindrical, 6–12 × 8–10 mm, flowers congested; ovaries depressed, 1.2 × 2.2 mm, off white; style short and thick, 0.4 × 1 mm, off-white; stigma depressed, 1.5 × 0.4 mm, entire, strongly echinulate, bright pale yellow; staminate flower zone cylindrical, 4.5–5.5 × 1–1.4 cm, flowers distant; staminate flowers 3–4(–5)-androus; stamens 2–2.5 mm long; filaments entirely or basally fused, column 1–1.5 × 0.5–0.8 mm; appendix conical, 1.7–2.4 cm × 9–10 mm, stipitate; stipe 2–10 × 4–6 mm, appendix apex obtuse, surface deeply corrugated separating rod-like papillae and short sinuous muri, off-white.
