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, if present, spicy or musty;

sepals displayed above bracts, widely spreading, green or variously purple marked, lanceolate, 38–60 × 5–12 mm, margins entire, apex acute;

petals long-lasting, erect, ± connivent, ± concealing stamens and ovary, purplish black on claw, greenish to yellow-green distally, sometimes all dark purple, occasionally slightly twisted, linear to narrowly spatulate, 4–8 × 0.8–1.2 cm, thick-textured, base slightly thickened and clawed, margins entire, apex rounded, lacking nipple;

stamens erect, connivent (clustered together, leaning upon each other), 16–25 mm;

filaments olive or purplish brown, 2.5–5 mm, very slender, widened basally;

anthers erect, straight or slightly incurved, olive-brown, 13–20 mm, ± slender, dehiscence latrorse;

connectives brownish, barely extending beyond anther sacs;

ovary pale greenish white basally, purplish distally, ovoid, 6-angled, 5.5–10 mm;

stigmas erect, divergent-recurved, distinct, purplish abaxially, sessile, almost linear, 6–10 mm, ± equaling ovary, ± not fleshy, very slightly widened basally.

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

dark purplish green or green, odor unreported, ovoid, obscurely angled, with remains of persistent stigma, 0.7–1.5 cm, pulpy, not juicy at time of separation from receptacle.
