few to many, decumbent-based to erect, unbranched except for short, leafy axillary shoots, hairs sparse, spreading, medium length to long, soft and dense, short to medium length, stipitate-glandular.

solitary or few to several, erect to ascending, less commonly bent at base, unbranched, sometimes branched distally, hairs spreading to appressed, fairly short, soft and moderately dense, matted, unbranched, not quite obscuring surface.

green or gray-green to purple (sometimes different on stems of same plant), linear-lanceolate, distal sometimes broadly lanceolate, 0.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acute to acuminate;

lobes ascending, linear to narrowly lanceolate, apex acute to acuminate, rarely obtuse.

green to purplish, linear to lanceolate or narrowly oblong, (1–)2–7(–9) cm, not fleshy, margins plane, sometimes ± wavy, involute, 0-lobed distally, sometimes 3-lobed, apex acute to acuminate, sometimes rounded.

2–12 × 1–3 cm;

bracts greenish to dull purplish or brownish throughout, or proximally greenish to dull purplish, distally pink to purple or magenta, rarely white, ovate, broadly lanceolate, or oblong, (0–)3–5-lobed;

lobes ascending to erect, lanceolate, medium length, arising above mid length, apex acute to rounded.

2–12(–15) × 1.5–4 cm;

bracts red to red-orange or orange throughout, sometimes crimson, cerise, pale salmon, or pale yellow throughout, or proximally pale green to straw colored, distally colored as above, proximal sometimes narrowly lanceolate, others elliptic to narrowly elliptic, oblong, obovate, or oblanceolate, 0–3(–5)-lobed;
