Flora of North America species comparison

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

several to many, erect or ascending, sometimes curved at base, unbranched or branched, sometimes with short, leafy axillary shoots, hairs spreading, short or long and distally short, stiff or soft, stipitate-glandular.

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 to sometimes purple, narrowly oblong or lanceolate to sometimes linear or narrowly ovate, (0.8–)1–5(–6.5) cm, not fleshy, margins wavy, flat or involute, 0–5-lobed, apex rounded or obtuse, rarely acute;

lobes ascending-spreading or divaricate, linear to narrowly oblong, apex acute.

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.

2.5–25 × 1.5–4 cm;

bracts proximally greenish, distally red, orange-red, or pale orange, rarely yellow, lanceolate or broadly lanceolate to oblong, (0–)3–5(–7)-lobed, plus 1–3 shallow teeth on apex of central lobe (var. clokeyi);

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

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 incurved, green to white, 0.5–1 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.

proximally pale green, green, or whitish, sometimes with a yellow central band, distally colored as bracts, 14–26(–28) mm;
