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 several, erect to ascending, decumbent at base, unbranched except for small, leafy axillary shoots, hairs weakly spreading to appressed, ± matted, especially distally on stem, fairly short and sparse proximally, longer and denser distally, soft, eglandular, becoming woolly, often obscuring surface.

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.

gray with hairs, surface green to purple, linear to narrowly lanceolate, 1–3.8 cm, not fleshy, margins plane, sometimes ± wavy, involute, 0–3-lobed, apex acute;

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

2.5–6 × 1–2.5 cm;

bracts greenish to pale yellow-green or very pale, dull purplish throughout, lanceolate to oblong, (0–)3(–5)-lobed;

lobes usually ascending, linear, medium length to long, arising near mid length, apex acute.

0–6 mm.

straight or slightly curved, 23–38(–40) mm;

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;

abaxial lip ascending, green, reduced, 1–2.5 mm, 10–20% as long as beak;

teeth erect or incurved, green or white, 1–2 mm.

straight, 18–25 mm;

tube 3.5–5.5 mm; subequal to calyx, or beak and sometimes abaxial lip exserted;

beak adaxially yellow, 6–8 mm, hairs moderately long, matted on midline, very short-glandular on sides;

abaxial lip green, inconspicuous, slightly pouched, 3.5–5.5 mm, 60–90% as long as beak;

teeth erect, white or yellow, 0.5–3 mm.

colored as bracts, 17–25(–30) mm;

abaxial and adaxial clefts (5–)7–15(–18) mm, 33–55% of calyx length, deeper than laterals, lateral 1–3(–5) mm, 5–10% of calyx length;

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

yellow, color mostly obscured by whitish hairs, 15–22 mm;

abaxial, adaxial, and lateral clefts (5.5–)7–12 mm, 35–55% of calyx length, often appearing shorter because matted hairs stitch proximal part of clefts shut, all 4 clefts subequal;

lobes broadly linear, apex acute.
