Flora of North America species comparison

few to many, erect or ascending, short-decumbent at base, unbranched, hairs dense, spreading to erect, ± short, soft, usually stipitate-glandular, longer ones sometimes 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.

pale green to dull reddish maroon, linear to linear-lanceolate, 0.8–3.5 cm, not fleshy, margins plane, slightly involute, 0–3(–5)-lobed, apex acuminate;

lateral lobes ascending to spreading, linear-lanceolate, usually arising from distal 1/2 of blade, usually narrower than central lobe, apex acuminate to 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.

10–40(–80 with age) × 0.5–2.5 cm;

bracts pale cream to pale greenish yellow throughout, often partly to entirely suffused with dull reddish purple to maroon, especially proximally, along veins, and with age, sometimes distal apices pale, dullish red, lanceolate to ovate, usually 3-lobed, central lobe sometimes with short teeth;

lobes spreading-ascending, linear-lanceolate, short to medium length, arising at or above mid length, 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).

tube 12–18 mm;

beak scarcely exserted, adaxially pale green to yellowish, 3–7 mm;

abaxial lip green, not inflated, grooved, 2.5 mm, 33–50% as long as beak;

abaxial and adaxial clefts 7–12 mm, 60% of calyx length, deeper than laterals, lateral 0.5–1 mm, 5–10% of calyx length;

lobes triangular, apex acute to obtuse.

green or yellowish green, 13–27(–28) mm;

abaxial and adaxial clefts 6–15 mm, 33–75% of calyx length, deeper than laterals, lateral 0.5–4 mm, 5–20% of calyx length;

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