blade bright green (in early anthesis rather succulent in appearance), usually well-marked with lighter and darker green spots, occasionally obscurely or scarcely mottled, mottling becoming obscure with age, ovate to broadly ovate, 11–18 × 12–17 cm, somewhat glossy, apex acuminate.

held well above ground, tips only touching ground in early anthesis, sessile;

blade dark green, mottling darker, mottled to varying degrees, mottling becoming obscure with age, broadly ovate-elliptic to elliptic, 7–15 × 4.6–6.7 cm, not glossy, apex rounded or barely acuminate.

sepals displayed above bracts, spreading, divergent, green, purple-streaked, lanceolate, 40–75 × 10–14 mm, margins entire, apex acute to round-acute;

petals long-lasting, conspicuous, spreading-erect to erect, tips incurving slightly, ± connivent, partially to completely concealing stamens and ovary, glossy dark maroon-red or purple, not spirally twisted, flat, oblanceolate, 5.5–11 × 2–3.5 cm, widest at or below middle, glossy, thick-textured, cuneate basally, margins ± flat, entire, apex round-acute;

stamens erect, straight, 15–26 mm, slightly concealing ovary;

filaments dark purple, 2–4 mm;

anthers dark maroon, 13–24 mm, dehiscence introrse;

connectives straight, barely extended beyond anther sacs;

ovary inconspicuous, purple, ovoid, round to 6-angled, 8–15 mm;

stigmas erect, distinct, subulate, 6–8 mm, fleshy, thickened basally.

anthers erect, straight, brownish purple, 10–16 mm, dehiscence introrse on broad connective;

connectives brown-purple, straight, essentially not extended beyond anther sacs;

ovary dark purple, ovoid, weakly 3-angled to smooth (rarely very obscurely 6-angled), angles often obscured in large, turgid ovary, 8–11 mm;

stigmas erect, divergent-recurved, distinct, purplish, subulate, 2–4 mm, fleshy.

dark reddish purple, ovoid to ellipsoid or weakly angled, 20–50 mm, fleshy.
