many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

solitary or few, sometimes several, erect or ascending, unbranched, rarely branched from base or from proximal inflorescence nodes, hairs spreading or reflexed, medium length, ± stiff, distally mixed with scattered, very short stipitate-glandular ones in inflorescences.

green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate.

green, often with a dull red-purplish cast, linear to narrowly lanceolate or narrowly oblong, (0.8–)1.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acuminate to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute.

3–34 × 1.5–3.5 cm;

flowers usually distichous, remote, except distalmost;

bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined;

lobes ascending, triangular, short, arising near apex, apex acute to obtuse.

2–6.5(–9) × 1.5–3.5 cm;

bracts yellow, pale orange, salmon, pink, dull brick red, or reddish orange throughout, rarely red, or proximally pale greenish, distally colored as above, narrowly lanceolate to lanceolate, 0–3(–7)-lobed;

lobes ascending to erect, linear to lanceolate, short to medium length, arising at or above mid length, central lobe apex obtuse, lateral ones obtuse to acute.

± curved, 25–38 mm;

tube 14–18 mm;

beak and often abaxial lip exserted;

beak adaxially dull orange or dull red, rarely yellow, 14–19 mm;

abaxial lip slightly curved, green, red, whitish, or yellow, not inflated, 2–2.5 mm, 15% as long as beak;

teeth incurved, dark green, 0.2–1 mm.

proximally whitish, green, or purple, distally colored as bracts, 9–18 mm;

abaxial clefts 6–6.5 mm, adaxial 7–9 mm, clefts 33+% of calyx length, deeper than laterals, lateral 1.5–4 mm, ca. 10% of calyx length;

lobes linear-lanceolate, apex acute.

colored as bracts, 20–27(–30) mm;

abaxial and adaxial clefts 6.5–13(–18) mm, 40–60% of calyx length, deeper than laterals, lateral (2–)4–7.5(–10) mm, 25% of calyx length;
