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 to several, ascending to erect, unbranched, hairs moderately dense, often retrorse, short, ± stiff, stipitate-glandular distally only in inflorescence.

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.

appressed-ascending, green to purplish, linear to narrowly lanceolate, distal sometimes broadly lanceolate, (1–)2.5–4(–5.5) cm, not fleshy, margins plane, involute, 0(–5)-lobed, apex rounded to acuminate;

lobes ascending, linear to narrowly lanceolate, apex 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.

2–7 × 1.5–2 cm;

bracts proximally pale green to pale yellow-green, distally pale to bright yellow or cream, rarely pale orange, elliptic, narrowly ovate, elliptic-oblong, broadly lanceolate, or ovate, (0–)3(–5)-lobed;

lobes ascending or spreading, narrowly lanceolate, short, arising near tip on distal bracts, central lobe apex rounded to truncate, lateral ones acute to rounded.

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;

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 to yellowish, distal 1/2 yellow, (16–)18–25 mm;
