Flora of North America species comparison

few to many, erect or ascending, unbranched or branched, hairs spreading, long, stiff, sometimes soft (especially in higher elevations), eglandular, mixed with shorter stipitate-glandular ones.

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.

green to purple or reddish brown, linear to narrowly oblong or linear-lanceolate, 1.4–7.4 cm, not fleshy, margins plane to ± wavy, involute or flat, 3(–7)-lobed, apex acuminate;

lobes spreading-ascending, linear, short to long moving up leaf axis, apex acute or obtuse.

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.

2.5–14 × 1–4 cm;

bracts greenish to pale yellow or reddish brown throughout, or proximally greenish to dull reddish purple, or ruddy brown, distally greenish to yellow-green or yellow, often aging dull reddish to dull purplish, lanceolate to oblong to ovate, 3–5(–9)-lobed;

lobes spreading to ascending, linear to narrowly lanceolate, long, proximal lobes arising below mid length, apex acute to obtuse.

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, 18–21 mm;

tube 11–16 mm; subequal to calyx, sometimes beak exserted;

beak adaxially green, 5–7(–8) mm;

abaxial lip white, often proximally reddish, prominent, scarcely expanded, ± cylindric, 2.5–4(–5) mm, 50–70% as long as beak, glabrous or obscurely puberulent;

teeth incurved to erect, white, 2.5 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.

colored as bracts, 12–25 mm;

abaxial and adaxial clefts 4–8 mm, 20–60% of calyx length, deeper than laterals, lateral (0–)1–3 mm, 7–25% of calyx length;

lobes linear, lanceolate, or triangular, apex acute, sometimes 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.
