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.

few to many, erect, ± decumbent or creeping at base, unbranched, sometimes branched, hairs spreading, medium length and long, soft, mixed with short stipitate-glandular ones.

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.

green to purple or brown-tinged, linear-lanceolate proximally, oblong-ovate or -obovate distally, 0.8–5.2 cm, not fleshy, margins plane, distalmost sometimes ± wavy, involute, 3–7(–11)-lobed, apex obtuse;

lobes erect to ascending, linear to linear-spatulate, very short, toothlike, usually arising from distal 1/3 of blade, apex rounded.

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.

2.5–25 × 1–4 cm;

bracts bright yellow throughout, or proximally greenish, distally bright yellow, sometimes deep yellow-orange, especially with age, oblong, elliptic, or obtuse to ovate, (0–)5–9(–13)-lobed, sometimes wavy-margined;

lobes erect to ascending, oblong, short to medium length, arising above mid length, central lobe apex rounded, lateral ones rounded to acute.

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 or slightly curved, 17–28 mm;

tube 12–15 mm;

beak exserted, adaxially green or greenish yellow, 6–8 mm;

abaxial lip yellow or greenish, reduced, not inflated, 2–3 mm, 25–33(–50)% as long as beak;

teeth ascending to erect, yellow, 0.5–1.5 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.

distally yellow, 13–22 mm;

abaxial and adaxial clefts 4–9.5 mm, 30–40% of calyx length, deeper than laterals, lateral 2.5–4.5 mm, ca. 25% of calyx length;

lobes linear to narrowly oblong or narrowly lanceolate, apex obtuse, sometimes rounded to acute.
