horizontal, brownish, short, thick, praemorse, not brittle.

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

1–5, 1.6–4.5 dm, smooth to rough near bract attachment.

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.

held well above ground, sessile;

blade green to purplish green, weakly to strongly mottled, mottling becoming obscure with age, ovate, ovate-elliptic, occasionally ovate-orbicular with margins overlapping, 7–18.5 × 7–13 cm, usually widest below middle, not glossy, base ± rounded, margins of distal 1/3 convex-curved to apex, apex acuminate to acute.

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.

borne upon bracts, erect, odor usually pleasant, faint, spicy, reminiscent of odor of bruised sweetshrub (Calycanthus) leaves, occasionally musty or unpleasant;

sepals widely spreading, variably green, purple-streaked to all purple, oblong-lanceolate, 27–60 × 7–13 mm, margins entire, apex rounded to acute;

petals long-lasting, erect, ± connivent, ± concealing stamens and ovary, maroon, maroon-purple, brownish purple, bronze, greenish purple, clear green, yellowish green, pale lemon yellow, or 2-colored, yellow distally with purple base, in occasional clones, flowers open or quickly fade to bright copper bronze, the particular color pattern is consistent from year to year, fading to browner tones with age except in yellow or green forms, not spirally twisted, shape quite variable across range, elliptic-obovate to oblanceolate, 4–7 × 0.9–2.7 cm, thick-textured, with widest portion at or above middle, narrowed to usually cuneate basally, not clawed, margins flat, entire, apex acute, rounded-acute to obtuse;

stamens erect, straight, brownish purple-green, 11–18 mm;

filaments brownish purple, 1.5–3.5 mm, widest at base;

anthers erect, straight, brownish gray, 7–14 mm, dehiscence latrorse or occasionally introrse;

connectives straight, scarcely (0.5 mm or less) if at all extended beyond anther sacs;

ovary maroon, ovoid to vase-shaped, weakly 6-angled or -ridged when mature, 12–15 mm;

stigmas erect, slightly diverging to spreading, distinct, purplish gray, linear-subulate to thickly subulate, 4–15 mm, fleshy.

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

green or with purple streaks, ovoid, very obscurely angled or angles no longer apparent, 2 × 1–1.5 cm, mealy or pulpy, fleshy, not juicy.
