Flora of North America species comparison

few to many, usually decumbent proximally, becoming ascending-erect, sometimes ascending, branched, sometimes with small, leafy axillary shoots, glabrate or ± pubescent distally, hairs sparse to moderately dense, spreading to ± appressed, short, soft, sometimes mixed with short-glandular ones below inflorescence.

several to many, erect or ascending, sometimes curved at base, unbranched or branched, sometimes with short, leafy axillary shoots, hairs spreading, short or long and distally short, stiff or soft, stipitate-glandular.

green, lanceolate to oblong or narrowly ovate, (0.5–)3–8 cm, sometimes thickened, not fleshy, margins plane, sometimes ± wavy, flat to involute, 0(–3)-lobed, apex acute to rounded;

lobes ascending or spreading, linear, narrowly lanceolate to oblong or triangular, short, apex acute to obtuse.

green to sometimes purple, narrowly oblong or lanceolate to sometimes linear or narrowly ovate, (0.8–)1–5(–6.5) cm, not fleshy, margins wavy, flat or involute, 0–5-lobed, apex rounded or obtuse, rarely acute;

lobes ascending-spreading or divaricate, linear to narrowly oblong, apex acute.

2.5–21 × 3–5 cm;

bracts proximally green, distally bright red to crimson or orange-red, sometimes orange or pale yellow-orange, oblong to narrowly ovate or narrowly obovate, (0–)3–5-lobed, sometimes with a pair of small teeth;

lobes ascending, linear to oblong, medium length, arising in middle 1/3, central lobe apex obtuse to rounded or truncate, lateral ones ± acute.

2.5–25 × 1.5–4 cm;

bracts proximally greenish, distally red, orange-red, or pale orange, rarely yellow, lanceolate or broadly lanceolate to oblong, (0–)3–5(–7)-lobed, plus 1–3 shallow teeth on apex of central lobe (var. clokeyi);

lobes ascending or spreading, linear, lanceolate, or oblanceolate, medium length or long, arising at or near mid length, central lobe apex obtuse to rounded, lateral ones acute.
