solitary or few, erect to ascending, unbranched, rarely branched, hairs spreading, long, soft, eglandular, others shorter and glandular.

pale green to dull reddish maroon, linear to linear-lanceolate, 0.8–3.5 cm, not fleshy, margins plane, slightly involute, 0–3(–5)-lobed, apex acuminate;

lateral lobes ascending to spreading, linear-lanceolate, usually arising from distal 1/2 of blade, usually narrower than central lobe, apex acuminate to acute.

green to sometimes brownish, rosette leaves persisting or withered at anthesis, oblanceolate to oblong-lanceolate, 1–3 cm, usually 0-lobed;

cauline leaves linear-lanceolate to oblong-lanceolate, 2–7(–8) cm, not fleshy, margins plane, sometimes wavy, involute, 3–7(–9)-lobed, apex acute to acuminate;

cauline leaves: lobes spreading to ascending, linear to oblong, (2–)5–25 mm, apex acuminate.

10–40(–80 with age) × 0.5–2.5 cm;

bracts pale cream to pale greenish yellow throughout, often partly to entirely suffused with dull reddish purple to maroon, especially proximally, along veins, and with age, sometimes distal apices pale, dullish red, lanceolate to ovate, usually 3-lobed, central lobe sometimes with short teeth;

lobes spreading-ascending, linear-lanceolate, short to medium length, arising at or above mid length, apex acute.

2–35 (longest in fruit) × 1.5–6 cm;

bracts proximally greenish to brownish green, distally red, sometimes orange, yellow, or white, lanceolate to obovate, 3(–5)-lobed;

lobes spreading-ascending, lanceolate and longer on proximal bracts, becoming oblanceolate, shorter, and wider on distal bracts, arising from distal 3/4 of blade, apex acute to rounded.

tube 12–18 mm;

beak scarcely exserted, adaxially pale green to yellowish, 3–7 mm;

abaxial and adaxial clefts 7–12 mm, 60% of calyx length, deeper than laterals, lateral 0.5–1 mm, 5–10% of calyx length;

lobes triangular, apex acute to obtuse.

colored as bracts, 17–23(–28) mm;

abaxial clefts 6–10 mm, adaxial 5–8 mm, clefts 33–50% of calyx length, deeper than laterals, lateral 0–1 mm, 0–5% of calyx length;

lobes oblong to triangular, apex rounded to truncate, sometimes emarginate.
