(1–)2–3(–many), round in cross section, 1.5–3+ dm, thick, glabrous.

sessile to subsessile;

blade rhombic, 10–20 × 6–20 cm, often wider than long, not glossy, base attenuate, apex acuminate.

sessile or subsessile (occasionally weakly cuneate basally);

blade dark green with maroon overtones early, ovate-rhombic, 12–20 × 8–15 cm, apex acuminate.

carried beneath bracts, odor faintly sweet;

sepals spreading, pale green, lanceolate-acuminate, 25–50 × 6–18 mm, margins involute, apex acuminate;

petals spreading to recurved distally, adaxially crimson, maroon-red, or brownish red, abaxially paler, grayish pink or rose, veins engraved, ovate-suborbicular, 3–6.5 × 4–6 cm, somewhat fleshy, base rounded and overlapping, margins entire, apex acute;

stamens conspicuous, ± erect to weakly recurved, 15–25 mm, longer than pistil at anthesis;

filaments grayish purple to blackish purple, longer than anthers, 5–12 mm, slender;

anthers weakly recurving, grayish purple to maroon, slender, dehiscence introrse;

connectives purple, barely equaling anther sacs;

ovary small, maroon or dark reddish purple, ± globose to conical-pyramidal, 6-ridged, 3–12 mm, basal attachment less than ovary width;

stigmas erect, recurved, distinct, gray-purple, not lobed adaxially, basally widened, ± linear distally, 2.5–6.5 mm, fleshy;

pedicel horizontal to declined-drooping, ± straight, 2–13 cm.

outfacing, erect, odorless;

sepals spreading, flat, green, very rarely streaked with maroon-purple, lanceolate, 20–55 × 12–23 mm, margins entire, apex acuminate or acute;

petals erect basally, recurving somewhat above middle to produce strongly funnelform corolla, obscuring ovary and base of style, white or rarely pink, without V-shaped or other markings, fading to dull pinkish purple, veins of adaxial surface conspicuous but not appearing engraved, shape variable, lanceolate to oblong, obovate, or, rarely, suborbicular, sides often parallel, 4–7.5 × 2–4 cm, thin-textured, base abruptly attenuate, margins overlapping basally, rolled, undulate-wavy in distal 1/2, apex ± acuminate;

stamens straight or barely recurved, 9–27 mm;

filaments white, much shorter than anthers, relatively thin;

anthers recurving slightly, pale yellow, strongly yellow when pollen exposed, long, 5–16 mm, slender, dehiscence introrse;

ovary inconspicuous, pale green or white, ovoid, 6-angled, 8–18 mm, basal attachment narrower than ovary width;

style barely united for 0.5–2 mm or merely closely grouped and separate;

stigmas erect, becoming spreading, weakly connate basally, pale green-white, uniformly linear, 3–18 mm, equaling or exceeding ovary, slender;

pedicel erect-ascending to strongly erect, 2–8+ cm.

dark reddish maroon, ovoid, obtusely angled, relatively small, 1–1.4 × 1–2 cm, pulpy.
