Flora of North America species comparison

solitary, erect to ascending, unbranched, sometimes branched from base, hairs spreading, short and medium, ± stiff, eglandular.

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.

green to purple-tinged, linear to linear-lanceolate, (1–)2–8 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate;

lobes spreading to ascending, filiform to lanceolate, apex sometimes acuminate.

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.

(1.5–)2–10(–19, –30 in fruit) × 1–2 cm;

bracts proximally green to pale brown, rarely dull reddish brown, distally white on apices, sometimes pale yellow or pale pink-purplish on apices, rarely greenish or dull reddish brown throughout, lanceolate or lanceolate-elliptic, 3(–5)-lobed;

lobes ascending, linear to lanceolate, long, arising below mid length, apex acuminate, acute, or obtuse.

(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, 10–25 mm;

tube 9–20 mm, not expanded distally;

beak exserted, straight, adaxially white, light yellow, or greenish, 3–5 mm, inconspicuously puberulent;

abaxial lip white or yellow with deep brown to purple spots, often becoming pink, slightly inflated, exserted or not, pouches 3, 2 mm wide, 1–1.5 mm deep, 3–4 mm, 75–80% as long as beak;

teeth erect, white, pale yellow, or pink, 0.5–1.2 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.

colored as bracts, (8–)15–23 mm;

abaxial and adaxial clefts (4–)6–8 mm, abaxial ca. 50% of calyx length, adaxial ca. 75% of calyx length, lateral 3–3.5 mm, 33% of calyx length;

lobes linear to narrowly triangular, apex acute to acuminate.

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.

glabrous.
