Flora of North America species comparison

few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

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.

green, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, apex acute to acuminate.

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.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones 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 or slightly curved, 14–22 mm;

tube 7–14 mm;

beak tip barely exserted from calyx;

beak adaxially greenish, 4–7 mm;

abaxial lip green to yellow, reduced, 1–4 mm, usually less than 67% as long as beak;

teeth erect, white, 0.5–1 mm.

colored as bracts, 15–20 mm;

abaxial and adaxial clefts 5.5–8 mm, 30–50% of calyx length, ± deeper than laterals, sometimes appearing subequal in pressed specimens, lateral 5–6 mm, ca. 33% of calyx length;

lobes linear to narrowly lanceolate, sometimes expanded towards apices, 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;
