Flora of North America species comparison

several to many, erect or ascending, branched or unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs ± dense, spreading to appressed, whitish or ashy gray, long, soft, much-branched, rarely unbranched, eglandular or obscurely glandular.

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

green, linear-lanceolate to narrowly or broadly lanceolate, 2–8 cm, not fleshy, margins plane to sometimes wavy, flat or involute, 0-lobed, sometimes 3–5-lobed distally, apex obtuse to rounded, sometimes acute;

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

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.

3–20 × 1.5–4 cm;

bracts proximally greenish, distally abruptly red, sometimes yellow, salmon, or orange-red, often with a narrow yellow medial band, lanceolate, broadly lanceolate, or oblong, 0–5-lobed;

lobes spreading to ascending, linear, long, arising near mid length, apex obtuse to 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.

slightly curved, 20–51 mm;

tube 12–21 mm;

beak long-exserted, adaxially green, yellow, or red, 12–33 mm;

abaxial lip deep green, reduced, 1–2.5 mm, ca. 10% as long as beak;

teeth incurved to erect, white, yellow, or green, 0.5–2 mm.

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.

proximally green to yellow, distally and abruptly colored as in distal bracts, often with a central yellow band, 13–28 mm;

abaxial clefts 5–13 mm, adaxial 8–14 mm, clefts 33–70% of calyx length, deeper than laterals, lateral 3–9 mm, 20–25% of calyx length;

lobes lanceolate to triangular, apex acute to acuminate.

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.
