Flora of North America species comparison

solitary or few, erect to ascending, unbranched, rarely branched, hairs spreading, long, soft, eglandular, others shorter and glandular.

few to many, ± curved at base, ascending or erect distally, unbranched, hairs moderately dense, spreading, medium length and long, soft, mixed with shorter stipitate-glandular ones.

green to sometimes brownish, rosette leaves persisting or withered at anthesis, oblanceolate to oblong-lanceolate, 1–3 cm, usually 0-lobed;

cauline leaves linear-lanceolate to oblong-lanceolate, 2–7(–8) cm, not fleshy, margins plane, sometimes wavy, involute, 3–7(–9)-lobed, apex acute to acuminate;

cauline leaves: lobes spreading to ascending, linear to oblong, (2–)5–25 mm, apex acuminate.

green, sometimes purple-tinged, lanceolate, broadly lanceolate, or narrowly ovate, 1–4.3 cm, not fleshy, margins plane, sometimes ± wavy, ± involute, 0–3-lobed, apex acute to acuminate;

lobes ascending, often narrowly oblanceolate, apex acute to acuminate.

2–35 (longest in fruit) × 1.5–6 cm;

bracts proximally greenish to brownish green, distally red, sometimes orange, yellow, or white, lanceolate to obovate, 3(–5)-lobed;

lobes spreading-ascending, lanceolate and longer on proximal bracts, becoming oblanceolate, shorter, and wider on distal bracts, arising from distal 3/4 of blade, apex acute to rounded.

3–8.5 × 1–4 cm;

bracts greenish or bright to sometimes dull red, sometimes scarlet, orange, or pale pink throughout, or proximally greenish, distally as above, ovate to elliptic, (0–)3-lobed;

lobes ascending, lanceolate to narrowly triangular, short, arising above mid length, apex acute to obtuse or acuminate.

straight, 18–31 mm;

tube 15–18 mm;

abaxial lip ± exserted, beak exserted, often whitish, yellowish, or faint dull reddish proximally, adaxially green distally, 7–10 mm;

abaxial lip green to yellowish, apex pink to yellow, reduced, ± protuberant, 1.5–4 mm, 20–33% as long as beak;

teeth erect, green or yellow, apices white, yellow, or pink, 2–4(–5) mm.

straight or slightly curved, 20–40 mm;

tube 27 mm;

abaxial lip often visible in abaxial cleft, sometimes exserted, beak usually exserted from calyx;

beak adaxially green to yellow, 8–14 mm;

abaxial lip red, black, green, white, or green and white, ± prominent, slightly rounded, 1.5–5 mm, ca. 33% as long as beak;

teeth ascending, green, bright red, pink, white, or yellow, 0.5–3 mm.

colored as bracts, 17–23(–28) mm;

abaxial clefts 6–10 mm, adaxial 5–8 mm, clefts 33–50% of calyx length, deeper than laterals, lateral 0–1 mm, 0–5% of calyx length;

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

brightly, conspicuously colored for at least distal 2/3, often throughout, providing much of inflorescence coloration, proximally pale whitish to pale pink, distally colored as in distal portion of bracts, sometimes colored throughout as in distal portion of bracts, 15–30 mm;

abaxial and adaxial clefts 7–14 mm, 33–50% of calyx length, deeper than laterals, lateral 1–5 mm, 5–15% of calyx length;

lobes narrowly to broadly triangular, apex rounded to acute.
