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

1–2, 1–2.2 dm, slender, essentially glabrous.

sessile or subsessile (occasionally weakly cuneate basally);

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

held well above ground, sessile;

blade mottled dark green over lighter green, mottling fading or blurring with time, ovate, elliptic to almost circular, 6–13 × 4–7 cm, apex acute to acuminate.

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.

erect, odor faintly pleasant, resembling sweetshrub (Calycanthus sp.);

sepals displayed above bracts, spreading, green, oblong-lanceolate, shorter than petals, 20–30 × 7–19 mm, margins entire, apex acute;

petals long-lasting, erect, ± connivent, ± concealing stamens and ovary to spreading distally, soft pale sulfur-yellow, fading to ± cream, sometimes slightly spirally twisted, widely spatulate, clawed basally, 2.2–5 × 0.9–1.5 cm, thick-textured, margins entire, often upraised adaxially, at least 1 petal with apex strongly apiculate, nipplelike, others with apex apiculate-acuminate;

claw green, sometimes obscurely marked or mottled with purple, broadly cuneate;

stamens incurved-erect, 8–15 mm;

filaments purple, 1–2.5 mm;

anthers erect, straight or arcuate, brown, 6.5–14 mm, dehiscence introrse-latrorse;

connectives straight, extending 1–2 mm beyond anthers;

ovary purplish, ovoid, 6-ridged, 2.5–8.5 mm;

stigmas divergent to erect, distinct, purplish white, subulate, short, 2–6 mm, ± fleshy.

pale green, odorless, ± globose, obscurely 6-angled, 1.2–1.6 × 0.8–1.4 cm, mealy, moist (not juicy).
