few to many, erect or ascending, unbranched or branched, hairs spreading, long, stiff, sometimes soft (especially in higher elevations), eglandular, mixed with shorter stipitate-glandular ones.

solitary or few to several, ascending, sometimes short-decumbent and rooting, branched from near base, sometimes distally, glabrous or glabrate with hairs very sparse, ± appressed, very short, soft, eglandular.

green to purple or reddish brown, linear to narrowly oblong or linear-lanceolate, 1.4–7.4 cm, not fleshy, margins plane to ± wavy, involute or flat, 3(–7)-lobed, apex acuminate;

lobes spreading-ascending, linear, short to long moving up leaf axis, apex acute or obtuse.

green, often brown- or purple-tinged, oblong to lanceolate to narrowly ovate or ovate, (1–)2–5.8 cm, not fleshy, margins plane, ± involute, deeply 3–7(–11)-lobed, sometimes with secondary lobes, apex narrowly acute;

lobes erect to ascending, lanceolate to linear-lanceolate to oblanceolate, apex acute.

2.5–14 × 1–4 cm;

bracts greenish to pale yellow or reddish brown throughout, or proximally greenish to dull reddish purple, or ruddy brown, distally greenish to yellow-green or yellow, often aging dull reddish to dull purplish, lanceolate to oblong to ovate, 3–5(–9)-lobed;
