Flower faintly ill-scented; sepals divergent-ascending, streaked with green to maroon, lanceolate to ovatelanceolate, 36–68 × 12–21 mm, margins entire, flat or slightly raised adaxially, apex acute; petals long-lasting, erect, ± connivent, ± partially concealing stamens and ovary, maroon-purple, brownish purple to brown, greenish streaked to green, rarely yellow, becoming brown, or occasionally bright copper-bronze with age, not spirally twisted, veins not engraved, obovate to oblanceolate, large in proportion to leaf size compared to many species, 5–9 × 1–2 cm, 2+ times longer than wide, widest at or just above middle, thick-textured, margins entire, flat, apex acute, obtuse, or rounded; stamens erect or incurving, 12–24 mm; filaments yellow, 2–3 mm; anthers erect, straight, rarely arcuate, yellow, 10–15 mm, dehiscence latrorse; connectives straight, projecting 1–2 mm beyond anther sacs; ovary dark red, brown, or gray, ellipsoid, strongly 6-angled, 6–13 mm; stigmas basally erect, tips recoiled upon ovary, distinct, green, white, or purple, linear, short, 3–12 mm, slightly thickened basally, not fleshy.
