Flora of North America species comparison

few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

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, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, apex acute to 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.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.

(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 or slightly curved, 14–22 mm;

tube 7–14 mm;

beak tip barely exserted from calyx;

beak adaxially greenish, 4–7 mm;

abaxial lip green to yellow, reduced, 1–4 mm, usually less than 67% as long as beak;

teeth erect, white to yellow, 1–2.5 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.

colored as bracts, 15–20 mm;

abaxial and adaxial clefts 5.5–8 mm, 30–50% of calyx length, ± deeper than laterals, sometimes appearing subequal in pressed specimens, lateral 5–6 mm, ca. 33% of calyx length;

lobes linear to narrowly lanceolate, sometimes expanded towards apices, apex acute.

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.
