few to many, erect, ascending, or decumbent, unbranched or branched, hairs sparse to dense, spreading, long, soft to ± stiff, eglandular, mixed with shorter stipitate-glandular ones.

gray-green, sometimes green, lanceolate-linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane, sometimes wavy, flat to involute, 0(–3)-lobed, apex acuminate;

green to purplish or brown, linear to broadly lanceolate, sometimes ovate, 1–6 cm, not fleshy, margins wavy, involute, (0–)3(–5)-lobed, apex rounded or narrowly acute to acuminate;

lobes spreading or ascending, lanceolate to broadly lanceolate, often short, apex acute to rounded.

3–30 × 3–4 cm;

bracts proximally green to dark purplish, distally red to crimson, sometimes pale salmon, linear-lanceolate to broadly lanceolate, 3–5-lobed;
