few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

several to many, erect or ascending, usually short-decumbent at base, unbranched, sometimes glabrous proximally, hairs spreading, long, soft, mixed with medium length to short stipitate-glandular ones only in inflorescence.

green, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, apex acute to acuminate.

green to deep purple, linear-lanceolate to broadly lanceolate (to linear on sterile shoots), 1.5–4(–5.5) cm, not fleshy, margins plane, flat, prominently veined, 0–3(–5)-lobed, apex acute to rounded;

lobes ascending, lanceolate, apex acute.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.

2–7(–10) × 1–3.5 cm;

bracts greenish to pale greenish yellow throughout, often aging dull reddish brown or reddish purple proximally, rarely dull reddish brown throughout, or proximally green, dull reddish brown, or reddish purple, distally greenish white, yellow, or cream, broadly lanceolate to widely oblong to ovate, 0–3(–7)-lobed;

lobes ascending, triangular to lanceolate, medium length, usually arising at or above mid length, rarely just below, central lobe apex obtuse to rounded, others acute.

tube 7–14 mm;

beak tip barely exserted from calyx;

beak adaxially greenish, 4–7 mm;
