Flora of North America species comparison

few to many, ascending to erect, branched, especially near base, sometimes unbranched, hairs sparse to dense, spreading to retrorse, long, sometimes short, soft to stiff, usually mixed with short-glandular ones, sometimes viscid.

solitary or few, erect, from a basal rosette that usually persists into anthesis, unbranched or few-branched from mid stem, glabrate proximally, hairy distally, hairs moderately dense, spreading, long, soft, mixed with short stipitate-glandular ones.

brown or purplish, sometimes green, linear to lanceolate or broadly lanceolate, 1.2–7(–7.5) cm, not fleshy, margins plane, sometimes ± wavy, involute or flat, (0–)3–5-lobed, rarely with secondary lobes, apex acuminate to rounded;

lobes spreading, oblong or lanceolate to linear-lanceolate, apex acute to rounded.

basal forming a persistent rosette, often withered at anthesis, usually suffused to varying degrees with red, sometimes green, oblanceolate to oblong-oblanceolate, 2–6 cm, not fleshy, margins plane, flat, 0-lobed, apex obtuse to broadly rounded to sometimes acute or subtruncate;

cauline green, sometimes proximal suffused with red or purple, linear to linear-lanceolate or linear-oblanceolate, 1.1–6.5 cm, not fleshy, margins plane, flat, 0–3(–5)-lobed, apex usually acute, rarely obtuse;

lobes erect to ascending, narrowly oblong to linear or narrowly lanceolate, to 1.8 cm, apex acute.

2.5–20 × 1.5–5 cm;

bracts proximally greenish or dull purplish, distally pink, magenta, pink-purple, reddish pink, pale yellow, pale yellow-orange, pale orange, or white, rarely reddish or orange-red, lanceolate to oblong, 3–5(–9)-lobed, sometimes with secondary lobes;

lobes spreading or ascending, oblanceolate or linear, proximal lobes often much longer than distal, proximal lobes arising below or a little above mid length, apex acute to rounded.

(2–)4–24(–33) × 2–4 cm;

bracts proximally greenish, distally bright yellow, rarely light orange, proximal narrowly lanceolate, leaflike, distal oblong to broadly rounded-oblanceolate, continuing to grow after anthesis and becoming greener and more leaflike, lateral lobes, if present, growing even more than central lobe, 0–5-lobed;

lobes erect, triangular or lanceolate, sometimes linear, short or medium length, arising above mid length, proximal bract apex acute, distal rounded, rarely central lobe shallowly toothed.

straight, 18–27(–32) mm;

tube 8–17 mm;

beak usually long-exserted, adaxially green or pink, 8–15 mm;

abaxial lip deep green, reduced, inconspicuous, 1–2.5 mm, 5–20% as long as beak;

teeth incurved to ascending, deep green, 0.5–1.5 mm.

straight or slightly curved, (15–)17–23 mm;

tube 8–11 mm;

abaxial lip rarely exserted, beak exserted;

beak adaxially green or yellow-green, 5–7 mm, margins yellow or yellow-green;

abaxial lip ascending, deep green, slightly inflated, 2–3 mm, 20–30% as long as beak, apex rounded;

teeth ascending, green, whitish, or yellow, 0.5–2 mm.

proximally green, yellow, brown, or purple, lobes colored as bract lobes, sometimes with a yellow band between proximal and distal parts, 13–25(–28) mm;

abaxial clefts 3–8 mm, adaxial 5–9(–12) mm, clefts 30–50% of calyx length, deeper than laterals, lateral (1–)1.5–4(–5) mm, 10–25% of calyx length;

lobes lanceolate to oblong, abaxials wider than adaxials, apex acute to rounded.

proximally whitish or pale green, often aging purple, distally yellow, (13–)15–18 mm;

abaxial and adaxial clefts 4–7 mm, 40–50% of calyx length, deeper than laterals, lateral 0–0.2 mm, ca. 0% of calyx length;

lobes curved, oblong, apex rounded to truncate, sometimes emarginate.
