Flora of North America species comparison

few to many, erect or ascending, unbranched, sometimes with inconspicuous, short, leafy axillary shoots, hairs spreading to erect, long, soft to stiff, mixed with shorter stipitate-glandular ones.

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, sometimes purple-tinged, margins sometimes red-brown, linear or narrowly to broadly lanceolate to narrowly oblong, oblanceolate, or ovate, 1–8.5 cm, not fleshy, margins plane or wavy, involute or flat, (0–)3–5(–7)-lobed, apex acute to rounded or acuminate;

lobes ascending, linear to narrowly lanceolate, much narrower than mid blade, apex acute to rounded.

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.

3–16(–30 in fruit) × 2–5 cm;

bracts proximally greenish to dull reddish purple, distally red to orange or yellow, sometimes crimson, scarlet, orange-red, red-orange, or burnt orange, often becoming paler and/or duller with age, lanceolate to oblong, ovate, or obovate, 3–5(–11)-lobed;

lobes spreading to ascending, linear to oblong or narrowly lanceolate, medium length or long, arising at or above mid length, central lobe apex obtuse to rounded or truncate, sometimes emarginate, truncate, or acute, lateral ones acute to obtuse.

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.

slightly curved, 17–38 mm;

tube 12–18 mm;

beak exserted, adaxially green, sometimes yellowish, rarely red-brown, 9–20 mm;

abaxial lip ascending, deep green, reduced, curved, 0.5–3 mm, to 10–33% length of beak;

teeth incurved, reduced, green, 0.5–1.2 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.

colored as bracts, sometimes with a yellow band proximal to red to orange apices, or ca. 1/2 yellowish and 1/2 reddish, 12–35 mm;

abaxial and adaxial clefts 7–12 mm, 33–65% of calyx length, deeper than laterals, lateral 2–7 mm, 15–30% of calyx length;

lobes triangular, linear, or oblong to lanceolate, apex acute or 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.
