Flora of North America species comparison

few to many, decumbent-based to erect, unbranched except for short, leafy axillary shoots, hairs sparse, spreading, medium length to long, soft and dense, short to medium length, stipitate-glandular.

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 or gray-green to purple (sometimes different on stems of same plant), linear-lanceolate, distal sometimes broadly lanceolate, 0.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acute to acuminate;

lobes ascending, linear to narrowly lanceolate, apex acute to acuminate, rarely obtuse.

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.

2–12 × 1–3 cm;

bracts greenish to dull purplish or brownish throughout, or proximally greenish to dull purplish, distally pink to purple or magenta, rarely white, ovate, broadly lanceolate, or oblong, (0–)3–5-lobed;

lobes ascending to erect, lanceolate, medium length, arising above mid length, apex acute to rounded.

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).
