Flora of North America species comparison

few to many, erect to ascending, unbranched, sometimes branched distally, sometimes with leafy axillary shoots, lanate to woolly, hairs dense, spreading to weakly appressed, white to yellowish, medium length, soft, moderately branched or unbranched in different populations, sometimes mixed, eglandular, rarely short stipitate-glandular, mostly obscuring surface.

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 to purple, often hidden by matted, white hairs, linear to narrowly oblong or narrowly lanceolate, (1–)2–7(–10) cm, not fleshy, margins plane, flat, sometimes involute, 0–3-lobed, apex rounded, sometimes acute;

lobes spreading, linear or narrowly oblong, 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.

2–19 × 1.5–5 cm;

bracts proximally pale greenish to greenish gray, distally bright red to orange-red, sometimes pinkish, magenta, or salmon, rarely yellow, oblong to narrowly lanceolate or narrowly oblanceolate, deeply 0–3(–5)-lobed;

lobes spreading, oblanceolate or linear, long, arising below mid length, distal bract apex usually 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.

curved in proximal 1/3, 23–35(–42) mm;

tube 12–17 mm;

beak exserted, adaxially greenish to yellowish, 11–22 mm;

abaxial lip dark green, reduced, 1–4 mm, ca. 20% as long as beak;

teeth incurved, reduced, green, 0.5–2.5 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.

proximally whitish to green, central band whitish, distal 1/3 colored as bract lobes, sometimes lighter or deeper, 15–29 mm;

abaxial and adaxial clefts 6–14 mm, ca. 50% of calyx length, deeper than laterals, lateral 0–5 mm, 0–5(–15)% of calyx length;

lobes oblong to broadly triangular, apex rounded, truncate, or emarginate.

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.
