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 to sprawling, usually profusely branched, including many small, leafy axillary shoots, hairs dense, retrorse, medium length, stiff, eglandular, distally spreading, long, soft, sometimes matted, very short-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, linear-lanceolate, distally sometimes broadly lanceolate, 2–4.5 cm on main branch, 0.5–1 cm on proximal part of side branches, not fleshy, margins plane, involute, sometimes flat, 0-lobed, apex acute to acuminate.

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.

2–4.5(–14 in fruit) × 1.5–4 cm;

bracts proximally greenish, distally red to reddish orange, broadly lanceolate to oblong, 0(–3)-lobed;

lobes ascending, lanceolate, short, arising above mid length, apex acute to obtuse.
