Flora of North America species comparison

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.

few to many, erect to ascending, unbranched or branched, hairs appressed to ± ascending, matted, long, soft, mixed with short-glandular ones, denser distally, sometimes obscuring surface.

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.

green, sometimes brown, linear to linear-lanceolate, 3–7 cm, not fleshy, margins plane, involute, 3–7-lobed, apex acute to rounded;

lateral lobes spreading, narrowly linear, apex acuminate.

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.

(3.5–)8–20 × 2–5.5 cm;

bracts proximally greenish, distally bright yellow, sometimes pale yellow to pale orange, sometimes aging white to pink, narrowly to broadly lanceolate or oblong, 3–5(–7)-lobed;

lobes spreading to ascending, linear, long, arising at or below mid length, apex obtuse to rounded.

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.

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.

green, pale green, or whitish, lobes colored as bracts, 12–18 mm;

abaxial and adaxial clefts 8–15 mm, 60–75% of calyx length, deeper than laterals, lateral 2.5–3 mm, 20% of calyx length;
