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.

few to several, ± prostrate, sometimes ascending, much-branched, with dense, matlike growth form, often with short, leafy axillary shoots, hairs dense, tangled, short to long, fairly stiff, branched, sometimes glandular, white-woolly.

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 deep purple, narrowly elliptic to oblong, ovate, or obovate, 1–3 cm, ± fleshy, margins plane or ± wavy, flat, 0-lobed, apex rounded, rarely 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;
