Flora of North America species comparison

few to several, decumbent to erect, sometimes leaning, unbranched or often much-branched distally, with a few short, leafy axillary shoots, hairs spreading, short, soft, stipitate-glandular, mixed with long-spreading, eglandular ones.

solitary or few, erect to erect-ascending, sometimes slightly curved at base, branched at base or unbranched, hairs spreading, long, stiff to soft, mixed with shorter stipitate-glandular ones.

gray-green, sometimes green, lanceolate-linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane, sometimes wavy, flat to involute, 0(–3)-lobed, apex acuminate;

lobes spreading-ascending, linear to narrowly lanceolate, apex acute.

brown or purplish, sometimes green, linear to narrowly oblong, 1–5 cm, not fleshy, margins wavy, mostly involute, to flat, 3–5-lobed, apex acute;

lobes spreading, linear, apex acute to obtuse.

3–30 × 3–4 cm;

bracts proximally green to dark purplish, distally red to crimson, sometimes pale salmon, linear-lanceolate to broadly lanceolate, 3–5-lobed;

2–17 × 1.5–6.5 cm;

bracts greenish throughout, narrowly lanceolate (ovate in outline), 3–5(–7)-lobed;
