Flora of North America species comparison

few to several, erect or ascending, unbranched, hairs spreading, long, soft, eglandular, mixed with short stipitate-glandular ones.

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, often with brown or purple veins, narrowly to broadly lanceolate, 1.5–4 cm, not fleshy, margins plane, ± involute, 0–3-lobed, apex acute to acuminate;

lobes spreading-ascending, narrowly lanceolate, apex acute to ± obtuse.

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–)3–6 × 1–2 cm; green to dull brown or dull reddish purple throughout, or proximally green to dull brown or dull reddish purple, distally yellow on apices, broadly lanceolate to ovate, (0–)3-lobed;

lobes ascending, narrowly lanceolate, long or short, arising near mid length, apex acute or acuminate.

(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, 14–16 mm;

tube 11–14 mm;

whole corolla included within calyx;

beak adaxially pale yellow, 1–2 mm;

abaxial lip deep green, slightly inflated, 4–5 mm, 67% as long as beak;

teeth ascending, pale, 1.5–2 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.

proximally green or pale with green veins, lobes yellow, sometimes becoming deep red with age, 12–15 mm;

abaxial and adaxial clefts 3–7 mm, 25–50% of calyx length, deeper than laterals, lateral 1–3(–4) mm, 8–20% of calyx length;

lobes triangular, adaxial segments longer than abaxials, apex acute or obtuse.

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.
