several to many, erect or ascending, branched or unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs ± dense, spreading to appressed, whitish or ashy gray, long, soft, much-branched, rarely unbranched, eglandular or obscurely glandular.

solitary, erect, unbranched or with few upright branches, hairs spreading, long, soft, mixed with shorter, eglandular and glandular ones.

green, linear-lanceolate to narrowly or broadly lanceolate, 2–8 cm, not fleshy, margins plane to sometimes wavy, flat or involute, 0-lobed, sometimes 3–5-lobed distally, apex obtuse to rounded, sometimes acute;

lobes sometimes divergent, ascending-spreading, linear, apex acute.

green to brown, proximal linear, distal lanceolate, 0.7–4(–8) cm, not fleshy, margins plane, flat, 0–3(–5)-lobed, apex acuminate;

lobes ascending-spreading, very long linear, apex acute.

3–20 × 1.5–4 cm;

bracts proximally greenish, distally abruptly red, sometimes yellow, salmon, or orange-red, often with a narrow yellow medial band, lanceolate, broadly lanceolate, or oblong, 0–5-lobed;
