Flora of North America species comparison

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.

solitary, sometimes few, proximally creeping, becoming rhizomatous, distally ascending to erect, unbranched or branched, glabrous proximally, glabrate distally, hairs ascending, medium length, soft, eglandular.

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.

widely spaced on stem, green, linear to lanceolate or narrowly oblong, 1.3–7.2 cm, not fleshy, margins plane, ± revolute, 0-lobed, apex broadly acute to acuminate, distalmost sometimes obtuse.

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.

2–13.5 × 1.5–4.5 cm;

bracts proximally greenish, rarely pink, distally pink, magenta, or purple, sometimes distally buff, dull yellow, cream, or light yellow-orange, ovate to elliptic or lanceolate, 0–5-lobed, sometimes also with 3 small teeth on center lobe;

lobes ascending or ± spreading, narrowly lanceolate to oblong, medium length, arising near or above mid length, apex acuminate to acute, sometimes obtuse.

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.

straight, 15–25 mm;

tube 7–12 mm;

beak and abaxial lip exserted above calyx lobes or ± pendently exserted from abaxial calyx cleft;

beak adaxially green to yellowish, 6–11 mm;

abaxial lip white to green, reduced, inconspicuous, pouches 3, small, 0.5–1.5 mm, 10–15% as long as beak;

teeth ascending, white to deep green, 0.5–1 mm.

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.

whitish, green, or pink, pale colored ones tending to age pink, lobes as in bracts, 9–17 mm;

abaxial and adaxial clefts 4.5–8 mm, 50% of calyx length, deeper than laterals, lateral 2–3 mm, 17–22% of calyx length;

lobes linear to oblanceolate, apex acute.
