Flora of North America species comparison

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

several to many, erect or ascending, often grayish, unbranched or often branched distally, glabrate proximally or hairy, especially distally, rarely glabrous, hairs sparse, spreading to appressed, usually curly, ± short, soft, sometimes mixed with sparse, short stipitate-glandular ones.

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.

often grayish or purplish, linear to narrowly lanceolate or narrowly oblong, (1–)2.5–5(–6.7) cm, not fleshy, margins plane or wavy, involute, deeply (0–)3–5(–7)-lobed, apex acute to acuminate;

lobes divaricate to spreading or ascending, linear, arising at or below mid length, apex acute to acuminate.

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.

3.5–20(–29) × 1–4 cm;

bracts pale green to pale yellow throughout, or proximally pale green to pale yellow, distally pale yellow to bright yellow, sometimes light orange, light red, or bright red, lanceolate to narrowly oblong or narrowly elliptic, slightly broader than leaves, usually 3–5-lobed;

lobes ± spreading, linear or narrowly lanceolate, short or long, proximal or all bracts arising near or below mid length, apex acute, sometimes narrowly obtuse.
