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.

few to many, erect or ascending, much-branched with many short, leafy axillary shoots, hairs recurved to retrorse, short, ± stiff, eglandular, often with some spreading, long 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.

green, linear-lanceolate to lanceolate, 1–3.5 cm, not fleshy, margins plane, sometimes ± wavy, flat to involute, (0–)3–7-lobed, apex acute to obtuse;

lateral lobes spreading, linear, much shorter and narrower than terminal lobe, apex acute.

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;

lobes spreading, linear, long, arising below mid length, apex acute, sometimes obtuse.

3–17 × 2–7.5 cm;

bracts green throughout, sometimes distalmost proximally green, distally red or red-orange on apices, lanceolate or broadly lanceolate, (0–)3–5-lobed;
