several, ascending to erect, decumbent at base, unbranched, sometimes branched, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

several, erect or ascending, branched or unbranched, sometimes with axillary tufts of leaves, hairs spreading to ± appressed, ± matted, short, soft, eglandular.

green to brown, linear, linear-lanceolate, lanceolate, or oblong (narrowly ovate nearing inflorescence), 1–4(–5) cm, not fleshy, margins wavy, flat or involute, (0–)2(–5)-lobed, apex acute;

lobes ascending-spreading, oblong to narrowly lanceolate, apex acute or obtuse.

green to purple, linear to narrowly lanceolate, 1.3–7 cm, not fleshy, margins plane, sometimes ± wavy, involute, 3–5-lobed, apex acute to obtuse;

lobes ascending, linear to narrowly lanceolate, apex acute.

2–14 × 1–3.5 cm;

bracts proximally greenish to greenish brown, distally pale yellow, cream, or yellow-green, sometimes yellow-orange or red (sometimes gradually differentiated from proximal coloration), lanceolate, broadly lanceolate, or oblong, 3(–5)-lobed, proximal wavy-margined;

lobes ascending, linear to narrowly lanceolate, long, arising near or above mid length, sometimes wavy-margined, apex acute to rounded.
