Flora of North America species comparison

solitary or few to several, ascending, sometimes short-decumbent and rooting, branched from near base, sometimes distally, glabrous or glabrate with hairs very sparse, ± appressed, very short, soft, eglandular.

solitary or few, erect, unbranched, rarely branched distally, hairs sparse to dense, spreading, sometimes shaggy (var. minor), short to long, soft to stiff, eglandular and/or sparsely to densely stipitate-glandular.

green, often brown- or purple-tinged, oblong to lanceolate to narrowly ovate or ovate, (1–)2–5.8 cm, not fleshy, margins plane, ± involute, deeply 3–7(–11)-lobed, sometimes with secondary lobes, apex narrowly acute;

lobes erect to ascending, lanceolate to linear-lanceolate to oblanceolate, apex acute.

green or purple to ± gray, linear to lanceolate, 2–10 cm, not fleshy, margins plane, sometimes wavy, ± involute, 0-lobed, apex acuminate to acute, sometimes obtuse.

3–15 × 2–4.5 cm;

bracts proximally greenish, distally bright red, scarlet, or pale reddish orange, rarely orange-yellow, often fading to pale yellowish orange with age, obovate to orbicular, fan-shaped, (3–)5–9(–13)-lobed, sometimes with secondary lobes;

lobes erect or ascending, lanceolate to triangular, short and medium length, usually arising at or above mid length, rarely below, apex acute.

5–40 × 1–4 cm;

bracts proximally greenish, distally red, red-orange, or pale orange, rarely yellow, on apices, narrowly lanceolate, sometimes narrowly oblong to spatulate distally, 0-lobed, plane-margined, apex acuminate (oblong to narrowly spatulate in var. spiralis).
