few to several, decumbent to erect, sometimes leaning, unbranched or often much-branched distally, with a few short, leafy axillary shoots, hairs spreading, short, soft, stipitate-glandular, mixed with long-spreading, eglandular ones.

several to many, erect to ascending, unbranched, sometimes branched, hairs spreading, long, soft, 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;

lobes spreading-ascending, linear to narrowly lanceolate, apex acute.

green, linear to narrowly or broadly lanceolate, (1–)3–5(–6) cm, not fleshy, margins wavy (obscure on many pressed specimens), involute, usually 0–3(–5)-lobed, apex broadly acute to rounded;

lobes widely spreading, linear to narrowly lanceolate, apex acute to acuminate.

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;
