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.

few, ascending, unbranched, sometimes branched, glabrate to sparsely hairy proximally, becoming densely hairy distally, proximal hairs appressed, white, short, soft, eglandular, distal hairs widely spreading to erect, white or yellowish, long to very long, soft, eglandular.

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.

green to sometimes red-brown or dull purplish, linear to linear-lanceolate, 1.5–4 cm, not fleshy, margins plane, sometimes ± wavy, involute, (0–)3(–5)-lobed, apex acute to acuminate;

lobes linear or linear-lanceolate, laterals ± divaricate, often abruptly up-curved from plane of main leaf blade, proximals usually 33–50% as long as leaf, 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.

2–11 × 1–2.5 cm;

bracts greenish or pale yellow, rarely purplish or deep red, often with dull purplish veins on proximal bracts, or proximally greenish or pale yellow, distally whitish, yellow, or orange-yellow, proximal sometimes linear-lanceolate, distal broadly lanceolate to oblong or obovate, (0–)3–5(–7)-lobed;

lobes ascending to erect, linear to lanceolate, short to medium length, arising above mid length, proximal bract apex acute, distal obtuse, rounded, or 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.

slightly curved, 10–22 mm;

tube 8–14 mm;

teeth of abaxial lip sometimes slightly exserted, beak exserted or subequal;

beak adaxially green to pale yellow, 5–8 mm;

abaxial lip deep yellow or green, reduced, forming a small pouch visible through front cleft, 3–5 mm, 50–75% as long as beak;

teeth ascending to erect, white or yellow, 1 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.

colored as bracts, proximally often paler, usually yellow throughout, 10–20 mm;

abaxial and adaxial clefts 7–14 mm, 40–50% of calyx length, deeper than laterals, lateral 0.5–1.5 mm, 5–15% of calyx length;

lobes triangular, apex acute to rounded.
