Flora of North America species comparison

solitary or few, erect or ascending, unbranched, sometimes branched, hairs spreading, short, medium, and long, soft, short and medium ones short stipitate-glandular.

many, ascending, white or grayish due to hairs branched, much-branched proximally, unbranched to sometimes branched on distal 1/2, also usually with short axillary branches, base often shrubby and with marcescent leaves of previous year, hairs dense, appressed to spreading, medium length, soft, much-branched, eglandular, white-woolly, obscuring surface.

green or ± yellow, lanceolate, elliptic, or oblong to narrowly ovate, 1–2(–2.5) cm, not fleshy, margins plane or wavy, involute, (0–)3–5(–7)-lobed, apex rounded to acute;

lobes ascending to erect, linear to lanceolate, apex rounded to acute.

whitish or grayish, linear to narrowly lanceolate or narrowly oblong, 0.9–5 cm, not fleshy, margins plane, involute, 0–3-lobed, apex obtuse to rounded;

lobes divergent, spreading, linear, apex acuminate to acute.

3–20 × 2–3.5 cm;

bracts proximally greenish to dull brown, distally red, orange-red, or scarlet, sometimes orange or yellow, broadly lanceolate or oblong, (0–)3–5-lobed;

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

2.5–20 × 1.5–3 cm;

bracts proximally green to dull pale purplish, distally red, scarlet, rose, yellow, orange, or cream, sometimes pink or white, lanceolate to oblanceolate, (0–)3–5-lobed;

lobes spreading, or distal ones erect, often oblanceolate, if 5-lobed, distal lobes usually very shallow, long or distal short, proximal bracts arising below mid length, distal ones arising near apex, apex rounded to truncate.

straight, 15–24(–26) mm;

tube 12–16 mm;

beak exserted, abaxial lip equal to calyx;

beak adaxially green or ± yellow-green, 7–10 mm, puberulent, stipitate-glandular;

abaxial lip deep green, reduced, rounded, 1–2 mm, 10–25% as long as beak;

teeth incurved to erect, light green, 0.5–1 mm.

straight or slightly curved, 16–27 mm;

tube (8–)10–12(–14) mm;

beak exserted or partially so, adaxially green, (7–)8.5–14 mm;

abaxial lip deep green, reduced, 1–3 mm, 20–33% as long as beak;

teeth incurved, reduced, green, 0.5 mm.

green or whitish with green veins, lobes colored as bract lobes or paler, 14–30 mm;

abaxial and adaxial clefts 5.5–8.5 mm, 30–40% of calyx length, deeper than laterals, lateral 1.5–4 mm, 20–25% of calyx length;

lobes oblong to narrowly triangular, apex obtuse to rounded.

proximally green, apices colored as bracts, 14–20(–22) mm;

abaxial and adaxial clefts 3.5–7(–9) mm, 33–40% of calyx length, deeper than laterals, lateral 0(–1) mm, 0(–7)% of calyx length;

lobes broadly triangular, apex of lobes and segments broadly rounded to truncate, segments, if present, obtuse.
