Flora of North America species comparison

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.

few to many, decumbent to ascending, much-branched, with leafy axillary shoots, villous, hairs spreading, long, stiff to soft, eglandular, mixed with short-glandular ones.

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.

gray-green becoming ± purple, or green, ± cup-shaped, oblong to narrowly elliptic or suborbicular, 0.5–2(–5) cm, ± fleshy, cupulate throughout, sometimes obscurely so on distal portion of stem, margins plane, flat to involute, 0–3-lobed, apex rounded;

lobes ascending, oblong to rounded, apex truncate or rounded, sometimes ± acute.

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.

5–23 × 1.5–3.5 cm;

bracts proximally greenish, distally bright red or red-orange, sometimes orange, oblong, ovate, or widely cuneate to widely obovate to suborbiculate, sometimes cup-shaped, 0–3-lobed, sometimes with 3 additional shallow teeth at tip of central lobe;

lobes erect, oblong to broadly triangular, short, arising above mid length, apex truncate, rounded, or obtuse, lateral ones sometimes acute.

tube 9–14 mm;

beak included or tip just barely exserted, adaxially green or pale yellow to deep burgundy, 3–5 mm;

abaxial lip green, burgundy, or reddish purple (in high-elevation form), little inflated, small, included, 2 mm, to 20% as long as beak;

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.

colored as bracts, often with a yellow central band, 20–31 mm;

abaxial and adaxial clefts 8–12 mm, ca. 50% of calyx length, deeper than laterals, lateral 2–6 mm, 10–15% of calyx length;
