Flora of North America species comparison

few to many, erect to ascending, unbranched or branched at proximal nodes, sometimes with short, leafy axillary branches, hairs sparse to dense, spreading, short and long, soft to stiff, unbranched, sometimes branched, eglandular, sometimes stipitate-glandular.

few to many, ascending to erect, much-branched, glabrous proximally, hairy distally, sometimes glabrous or hairy throughout, hairs sparse, sometimes dense, spreading to slightly retrorse, short to long, ± stiff, eglandular.

green or purplish, sometimes red-brown, linear or linear-oblong to broadly lanceolate, 2–13 cm, not or ± fleshy, margins wavy or plane, flat or involute, 0–5-lobed, sometimes with small secondary lobes, short, leafy axillary shoots common, usually conspicuous, apex acuminate or acute to rounded;

lobes spreading, linear to lanceolate, lateral lobes almost as wide as mid blade, apex acute to rounded.

± yellow to gray-green, sometimes becoming ± purple, linear to narrowly lanceolate, (1–)2–10 cm, not fleshy, rarely ± thickened and fleshy, margins plane, involute, 0–3(–5)-lobed, apex acute or acuminate;

lobes spreading, linear, apex acute to acuminate.

3–25(–30) × 1.5–5 cm;

bracts proximally green or deep purple, distally red, crimson, scarlet, pink, pinkish purple, pinkish red, or yellow, sometimes rose magenta, red-orange, or orange, oblanceolate or obovate to oblong or lanceolate, (0–)3–5(–7)-lobed;

lobes spreading to ascending, linear to obovate, long, proximal lobes at or arising below mid length, apices acute to obtuse, center lobe sometimes rounded.

4–20 × 2–7.5 cm;

bracts red to red-orange throughout, sometimes pale green, yellow, magenta, pink-purple, or white throughout, or proximally pale greenish to straw colored, distally colored as above, lanceolate to narrowly lanceolate or narrowly oblong, 3(–5)-lobed;

lobes spreading to ascending, narrowly lanceolate to linear, shorter than central lobe, arising in proximal 1/3, apex obtuse to acuminate.
