Flora of North America species comparison

few to many, usually decumbent proximally, becoming ascending-erect, sometimes ascending, branched, sometimes with small, leafy axillary shoots, glabrate or ± pubescent distally, hairs sparse to moderately dense, spreading to ± appressed, short, soft, sometimes mixed with short-glandular ones below inflorescence.

few to many, erect or ascending, often branched distally, sometimes unbranched, sometimes with short axillary shoots, proximal hairs retrorse to appressed, short to moderately long, distal hairs spreading, longer, soft, often mixed with short stipitate-glandular ones.

green, lanceolate to oblong or narrowly ovate, (0.5–)3–8 cm, sometimes thickened, not fleshy, margins plane, sometimes ± wavy, flat to involute, 0(–3)-lobed, apex acute to rounded;

lobes ascending or spreading, linear, narrowly lanceolate to oblong or triangular, short, apex acute to obtuse.

green, linear-lanceolate, rarely broadly lanceolate, (1.2–)2.5–8(–9) cm, not fleshy, margins plane, flat or involute, 0(–3)-lobed, apex acute to rounded;

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

2.5–21 × 3–5 cm;

bracts proximally green, distally bright red to crimson or orange-red, sometimes orange or pale yellow-orange, oblong to narrowly ovate or narrowly obovate, (0–)3–5-lobed, sometimes with a pair of small teeth;

lobes ascending, linear to oblong, medium length, arising in middle 1/3, central lobe apex obtuse to rounded or truncate, lateral ones ± acute.

(2–)4–17 × 1.5–3 cm;

bracts proximally greenish, distally red, orange-red, or orange, proximal sometimes lanceolate, distal broadly lanceolate to ovate, (0–)3(–7)-lobed;

lobes spreading to ascending, linear to lanceolate, long, arising near or below mid length, central lobe apex rounded, lateral ones acute.

tube 10–20 mm;

abaxial lip often visible through front cleft, very rarely almost exserted, beak exserted;

beak adaxially green or yellowish, 10–16 mm, surface inconspicuously puberulent;

lobes broadly triangular to oblong, apex obtuse to acute or rounded.

proximally pale yellow or greenish, distally colored as bracts, (15–)18–28 mm;

abaxial and adaxial clefts 6–12 mm, 40–45% of calyx length, deeper than laterals, lateral 2.5–8 mm, 20–30% of calyx length;
