Flora of North America species comparison

solitary or few to several, erect, often decumbent at base, unbranched, sometimes branched, hairs spreading, long, soft, eglandular, mixed with shorter, sometimes stiff, stipitate-glandular ones.

many, spreading and ascending, much-branched, with short, leafy axillary shoots, proximal stems 1+ cm wide, hairs dense, spreading, matted, white, medium length, soft, stellate, sometimes mixed with short stipitate-glandular ones especially near inflorescence, partially obscuring surface.

green, sometimes with prominent red-purple veins, lanceolate-linear to broadly lanceolate, 2.5–4.5(–7) cm, not fleshy, margins plane, flat, (0–)3–5(–9)-lobed, apex acuminate to acute;

lobes spreading-ascending, narrowly lanceolate, arising at or above mid length, apex acute.

ash gray, linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane or slightly wavy, involute, 0–7-lobed, apex rounded to obtuse, surfaces almost obscured by hairs, at least when young;

lobes spreading to ascending, linear to narrowly oblong, apex acute to acuminate.

3.5–26 × 1.5–3.5 cm;

bracts pale green, pale greenish yellow, or pale yellow throughout, or proximally pale green, pale greenish yellow, pale yellow, or reddish purple, distally white, yellow, pink, dull purple, or dull reddish purple, sometimes with a purple band below that, sometimes with veins darker than background color, lanceolate to oblong, 0–5(–9)-lobed;

lobes ascending or spreading, linear to narrowly lanceolate, often short, arising above mid length, central lobe apex rounded, lateral ones acute to rounded.

(3–)7.5–11.5 × 1.5–3.5 cm;

bracts proximally greenish, distally ± pale yellow, proximals sometimes greenish throughout, linear to narrowly lanceolate or narrowly oblong, (3–)5–7-lobed;

lobes spreading, linear to narrowly oblong, long, proximal lobes arising below mid length, apex obtuse to acute.

straight, 19–25(–28) mm;

tube (13–)15–20 mm;

abaxial lip included, beak not or slightly exserted;

beak adaxially green to yellow-green, 4–7 mm;

abaxial lip yellow, prominent, inflated, 2–4.5 mm, ca. 75% as long as beak;

teeth incurved to erect, white, 1.3–2.1 mm.

curved in proximal 1/3, 15–25 mm;

tube 11 mm;

abaxial lip not exserted, sometimes visible in abaxial cleft, beak exserted;

beak adaxially green or dull yellow, 7–9 mm;

abaxial lip deep green, reduced, 1–2 mm, less than 25% as long as beak;

teeth incurved, green, 0.7–1 mm.

green, pale green, or pale yellow, lobes yellow to pale yellow, 20–30 mm;

abaxial and adaxial clefts 6.6–14 mm, 33–50% of calyx length, deeper than laterals, lateral 0–4(–4.5) mm, 0–15% of calyx length;

lobes broadly rounded to triangular, apex obtuse to rounded.

colored as bracts, 10–20 mm;

abaxial and adaxial clefts 5.5–7 mm, 50% of calyx length, deeper than laterals, lateral 0–1 mm, 0–8% of calyx length;

lobes oblong, apex truncate to rounded or obtuse, rarely emarginate, inner surface glandular.
