Flora of North America species comparison

few to many, erect to ascending, rarely proximally decumbent or creeping and rooting at nodes, usually branched, glabrous, glabrate, or hairy, hairs spreading to ± retrorse, short to long, soft to stiff, rarely stipitate-glandular.

solitary or few to several, erect, often decumbent at base, unbranched, sometimes branched, hairs spreading, long, soft, eglandular, mixed with shorter, sometimes stiff, stipitate-glandular ones.

green to purple, linear to lanceolate, narrowly elliptic, narrowly oblong, or ovate, (1.5–)3–8(–9.5) cm, thin and not fleshy or slightly to moderately thickened and slightly fleshy, margins plane, rarely wavy, flat to involute, whole leaf sometimes recurved downward, 0(–5)-lobed, apex acute to obtuse, sometimes rounded;

lobes ascending-spreading, narrowly lanceolate, apex acute.

green, sometimes with prominent red-purple veins, lanceolate-linear to broadly lanceolate, 2.5–4.5(–7) cm, not fleshy, margins plane, flat, (0–)3–5(–9)-lobed, apex acuminate to acute;

lobes spreading-ascending, narrowly lanceolate, arising at or above mid length, apex acute.

3–15(–22) × 1.5–5.5 cm, often bearing a thin, white, powdery exudate, especially on bract surfaces;

bracts greenish, scarlet, red, red-orange, or pale orange throughout, sometimes pink, magenta, pink-purple, yellow, greenish yellow, white, or salmon throughout, or proximally greenish, distally colored as above, lanceolate to oblong-ovate, 0–5(–7)-lobed, central lobes sometimes distally apiculate;

lobes erect, linear to lanceolate, oblong, or oblanceolate, short or medium length, arising near or above mid length, central lobe apex obtuse, rounded, or truncate, lateral ones rounded to acute or acuminate.

3.5–26 × 1.5–3.5 cm;

bracts pale green, pale greenish yellow, or pale yellow throughout, or proximally pale green, pale greenish yellow, pale yellow, or reddish purple, distally white, yellow, pink, dull purple, or dull reddish purple, sometimes with a purple band below that, sometimes with veins darker than background color, lanceolate to oblong, 0–5(–9)-lobed;

lobes ascending or spreading, linear to narrowly lanceolate, often short, arising above mid length, central lobe apex rounded, lateral ones acute to rounded.

lobes linear or narrowly lanceolate to narrowly triangular, apex acute to acuminate or obtuse.

green, pale green, or pale yellow, lobes yellow to pale yellow, 20–30 mm;
