Flora of North America species comparison

few to several, decumbent to erect, sometimes leaning, unbranched or often much-branched distally, with a few short, leafy axillary shoots, hairs spreading, short, soft, stipitate-glandular, mixed with long-spreading, eglandular ones.

several to many, erect to ascending, or decumbent, inflorescence erect in high-elevation form, unbranched, sometimes branched, hairs dense, spreading, ashy gray, short and long, soft, mixed with short stipitate-glandular ones.

gray-green, sometimes green, lanceolate-linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane, sometimes wavy, flat to involute, 0(–3)-lobed, apex acuminate;

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

green, brown, purple, or deep gray, linear or narrowly to broadly lanceolate to sometimes ovate, 0.7–3 cm, not fleshy, margins plane, slightly involute, 0(–3)-lobed, apex acuminate;

lobes ascending to spreading, linear to lanceolate, apex acuminate.

3–30 × 3–4 cm;

bracts proximally green to dark purplish, distally red to crimson, sometimes pale salmon, linear-lanceolate to broadly lanceolate, 3–5-lobed;

lobes spreading, linear, long, arising below mid length, apex acute, sometimes obtuse.

1–8.5 × 2–5 cm;

bracts proximally greenish or deep reddish purple, distally burnt orange, sometimes yellow or deep red to deep burgundy, proximal sometimes lanceolate with narrow lobes, distal or all bracts broadly lanceolate to oblong or slightly oblanceolate, (0–)3–5-lobed, appearing dusty with dense, short stipitate-glandular hairs, many with a nodulose to pillarlike, crystallized, usually pigmented exudate, papillose at 40x;

lobes ascending-spreading, oblong or oblanceolate, short, arising above mid length, central lobe apex rounded, often expanded, rounded, or truncate, lateral ones acute to rounded.

straight or slightly curved, 20–40 mm;

tube 15–23 mm;

abaxial lip exserted to included, beak much exserted;

beak adaxially yellow-green to reddish, 9–18 mm;

abaxial lip green, reduced, 0.5–1.5 mm, 5–20% as long as beak;

teeth incurved, green, (0–)0.5–1.5 mm.

straight, 12–18 mm;

colored as bracts, 15–20 mm;

abaxial clefts 3.4–6.2 mm, adaxial 4.5–9 mm, clefts 25–33% of calyx length, deeper than laterals, lateral 0.5–2 mm, 5–10% of calyx length;

lobes narrowly triangular, often slightly unequal, apex acute.

colored as bracts, sometimes whitish proximally, 1.5–20 mm (shorter in upper elevation form);

abaxial and adaxial clefts 3.5–8 mm, 30–50% of calyx length, all 4 clefts subequal;

lobes linear to narrowly oblong or oblanceolate, apex obtuse to rounded, densely stipitate-glandular.
