Flora of North America species comparison

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.

solitary or few, erect, unbranched, rarely branched distally, hairs sparse to dense, spreading, sometimes shaggy (var. minor), short to long, soft to stiff, eglandular and/or sparsely to densely stipitate-glandular.

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.

green or purple to ± gray, linear to lanceolate, 2–10 cm, not fleshy, margins plane, sometimes wavy, ± involute, 0-lobed, apex acuminate to acute, sometimes 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.

5–40 × 1–4 cm;

bracts proximally greenish, distally red, red-orange, or pale orange, rarely yellow, on apices, narrowly lanceolate, sometimes narrowly oblong to spatulate distally, 0-lobed, plane-margined, apex acuminate (oblong to narrowly spatulate in var. spiralis).

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.

straight, 13–39 mm;

tube 11–16(–20) mm;

beak partially to completely exserted, sometimes included, adaxially yellow, pale orange to red-orange, reddish brown, green, or white, 5–15(–20) mm;

abaxial lip yellow, white, red, deep red, red-violet, or green, colored as or strongly contrasting with rest of corolla, small but jutting out at 90° from axis of corolla, often readily visible through abaxial cleft, 1–3 mm, 5–25% as long as beak;

teeth spreading to strongly incurved, green, white, yellow, red, or red-purple, 0.2–1 mm.

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.

green or yellowish green, 13–27(–28) mm;

abaxial and adaxial clefts 6–15 mm, 33–75% of calyx length, deeper than laterals, lateral 0.5–4 mm, 5–20% of calyx length;

lobes linear to narrowly triangular or narrowly lanceolate, apex acute or acuminate.
