Flora of North America species comparison

solitary, sometimes few, erect from a slender, creeping base, unbranched, glabrate or hairs spreading, long, soft to ± stiff and shorter, stipitate-glandular.

few to many, decumbent to ascending, much-branched, with leafy axillary shoots, villous, hairs spreading, long, stiff to soft, eglandular, mixed with short-glandular ones.

green, distal sometimes red-tipped, linear-lanceolate, sometimes distal broadly lanceolate or ovate, 1.2–8.9 cm, not fleshy, margins plane, flat or slightly involute, 0–5(–7)-lobed, apex acute to acuminate, sometimes obtuse or rounded;

lateral lobes spreading-ascending or widely spreading, linear, often much narrower than mid blade, apex acute.

gray-green becoming ± purple, or green, ± cup-shaped, oblong to narrowly elliptic or suborbicular, 0.5–2(–5) cm, ± fleshy, cupulate throughout, sometimes obscurely so on distal portion of stem, margins plane, flat to involute, 0–3-lobed, apex rounded;

lobes ascending, oblong to rounded, apex truncate or rounded, sometimes ± acute.

2.5–9(–11) × 2–5.5 cm;

bracts proximally greenish, distally abruptly red to orange-red, often with a yellow, rarely purplish, medial band, narrowly lanceolate to ovate, 3–7(–11)-lobed;
