few to many, erect or ascending, unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs spreading to erect, long, soft to stiff, mixed with shorter stipitate-glandular ones.

several to many, erect to ascending, branched, sometimes unbranched, hairs moderately dense, spreading, ± matted, ash gray, branched, sometimes unbranched, medium length, soft, often mixed with shorter, unbranched, stipitate-glandular ones, not obscuring surface.

green, sometimes purple-tinged, margins sometimes red-brown, linear or narrowly to broadly lanceolate to narrowly oblong, oblanceolate, or ovate, 1–8.5 cm, not fleshy, margins plane or wavy, involute or flat, (0–)3–5(–7)-lobed, apex acute to rounded or acuminate;

lobes ascending, linear to narrowly lanceolate, much narrower than mid blade, apex acute to rounded.

ash gray, linear-lanceolate to narrowly oblong or narrowly oblanceolate, 2–6 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex acute to obtuse;

lobes spreading, narrowly lanceolate, apex acute to obtuse.

3–16(–30 in fruit) × 2–5 cm;

bracts proximally greenish to dull reddish purple, distally red to orange or yellow, sometimes crimson, scarlet, orange-red, red-orange, or burnt orange, often becoming paler and/or duller with age, lanceolate to oblong, ovate, or obovate, 3–5(–11)-lobed;

lobes spreading to ascending, linear to oblong or narrowly lanceolate, medium length or long, arising at or above mid length, central lobe apex obtuse to rounded or truncate, sometimes emarginate, truncate, or acute, lateral ones acute to obtuse.
