1–3, round in cross section, 1.4–4 dm, slender to stout, glabrous.

often carried quite horizontally, well above ground, sessile;

blade light green or bronze-green, strongly mottled in dark green with central light green stripe, mottling becoming obscure with age but less so than in most species, elliptic-ovate, rarely ± orbicular, 6.7–12 × 3.8–6 cm, not glossy, base evenly tapered to broad attachment, apex obtuse-acute.

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.

borne directly on bracts, odor of putrid meat, especially when in strong sunlight;

sepals displayed above bracts, carried almost horizontally, green or green streaked with dark maroon, lanceolate, 16–40 × 4–6 mm, thick-textured, margins entire, apex acute;

petals long-lasting, erect, very gradually incurved from base to apex, ± connivent, ± concealing stamens and ovary, pinkish purple, light to reddish purple, brownish purple, rarely yellow, fading to brownish tones with age, not spirally twisted, not inrolling with age, veins not engraved, narrowly elliptic to linear-lanceolate, 2–5 × 0.3–0.5 cm, thick-textured, not glossy, margins entire, flat, acute at apex;

stamens relatively prominent, erect, 9–25 mm;

filaments dark maroon, 3–6 mm, dilated basally;

anthers straight, dark maroon-black, 8–15 mm, dehiscence introrse;

connectives straight, extended 1–1.5 mm beyond anther sacs;

ovary red-purple, ovoid, hexagonal in cross section, 5–12 mm, broadly attached;

stigmas erect, divergent-recurved, distinct, dark purple, subulate, nearly as long as ovary, fleshy.

erect, odor faintly spicy and bananalike;

sepals displayed above bracts, spreading almost to horizontal, often suffused or streaked with purple-maroon, lanceolate-linear, 22–50 × 5–7 mm, margins entire, apex rounded-acute, recurving slightly;

petals long-lasting, spreading-erect, ± connivent, ± concealing stamens and ovary or sometimes slightly spreading early, only partially obscuring stamens, becoming more erect and even touching in the manner of Trillium cuneatum when older, clear dark red-maroon, or reddish purple, without muddy or brown tones of many purple sessile species, or, rarely, purple basally and yellow toward apex, or clear sulfur yellow, not spirally twisted, narrowly oblanceolate-spatulate to linear-spatulate, widest above middle, narrowing to apex, 4–7 × 0.7–1.7 cm, thick-textured, margins entire, slightly involute in proximal 1/2, apex acute to round-acute;

stamens erect, 12–20 mm;

filaments dark purple, 2–3 mm, widest at base, much shorter than anther sacs;

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.

purplish brown, ovoid, 6-angled at least apically, fleshy.

dark purplish green, odor not reported, ovoid, obscurely 3- to 6-angled, bearing persistent stigma, 1 × 2 cm, pulpy.
