Flora of North America species comparison

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.

many, spreading to erect, much-branched, with numerous short, leafy axillary shoots, hairs moderately dense, spreading, medium length to long, stiff to soft, shorter stipitate-glandular ones.

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.

gray-green becoming ± purple to sometimes green as hairs are lost, oblong to lanceolate-oblong or broadly lanceolate, 0.5–2 cm, ± fleshy, cupulate, sometimes obscurely so on distal portion of stem, margins plane, sometimes ± wavy, involute, 0–3-lobed, apex truncate or broadly rounded to obtuse;

lobes erect to ascending, oblong, apex 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.

2.5–20 × 1.5–5 cm;

bracts proximally green to dull, deep brownish purple, distally bright red, red-orange, or orange, sometimes yellow to yellow-orange, oblong or broadly lanceolate to widely obovate or ovate, often cup-shaped, center lobe often expanded distally, 0–3(–5)-lobed, often wavy-margined;

lobes ascending, oblong, short or long, arising near or above mid length, central lobe apex mostly rounded to truncate, sometimes with 5 or so very shallow teeth.

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.

slightly curved, 19–30 mm;

tube 8.5–15 mm;

beak exserted, adaxially green, 8.5–15 mm;

abaxial lip ascending, deep green, reduced, 0.5–1 mm, 5–10% as long as beak;

teeth incurved, reduced, green or white, 0.2–0.5 mm.

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.

proximally light green to sometimes purple, distally colored as bracts, 15–25 mm;

abaxial and adaxial clefts 6–9.5 mm, 33–50% of calyx length, deeper than laterals, lateral 1–3 mm, ca. 12% of calyx length;

lobes broadly triangular to oblong, apex rounded to obtuse, rarely acute.
