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 or few to many, erect, branched distally, sometimes unbranched or with short, leafy branches in axils of leaves, glabrous, sometimes hairy, hairs moderately dense, spreading, short, 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.

green, sometimes purplish, linear or narrowly lanceolate, 1–9 cm, not fleshy, margins plane, involute, 3–5(–9)-lobed, apex acuminate to narrowly acute;

lobes spreading, linear, arising near or below mid length, apex acute, rarely 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.

3–15(–20) × 1.5–3 cm;

bracts proximally pale greenish to pale yellowish green, distally white, cream, or pale yellow, sometimes pale greenish, pale yellow-green, or pale yellow throughout, lanceolate to narrowly elliptic, 3–5(–7)-lobed;

lobes ascending or spreading, linear to very narrowly linear, long, arising above or below mid length, apex acute to 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 or ± curved, 16–25 mm;

tube 15–17 mm;

beak exserted from calyx, adaxially green, 5–7 mm;

abaxial lip deep green, reduced, exserted through abaxial cleft, 1–4 mm, 40–60% as long as beak;

teeth erect, white, 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.

green, rarely pale purple, lobes white, cream, or pale yellow, 18–24(–27) mm;

abaxial clefts (6–)8–16 mm, adaxial 4–10(–14) mm, abaxial 45–60% of calyx length, adaxial 15–40% of calyx length, deeper than laterals, lateral 1–4 mm, 5–15% of calyx length;

lobes narrowly triangular to linear, apex acute.
