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.

few, ascending, unbranched, sometimes branched, glabrate to sparsely hairy proximally, becoming densely hairy distally, proximal hairs appressed, white, short, soft, eglandular, distal hairs widely spreading to erect, white or yellowish, long to very long, 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 to sometimes red-brown or dull purplish, linear to linear-lanceolate, 1.5–4 cm, not fleshy, margins plane, sometimes ± wavy, involute, (0–)3(–5)-lobed, apex acute to acuminate;

lobes linear or linear-lanceolate, laterals ± divaricate, often abruptly up-curved from plane of main leaf blade, proximals usually 33–50% as long as leaf, apex acuminate to acute.

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.

2–11 × 1–2.5 cm;

bracts greenish or pale yellow, rarely purplish or deep red, often with dull purplish veins on proximal bracts, or proximally greenish or pale yellow, distally whitish, yellow, or orange-yellow, proximal sometimes linear-lanceolate, distal broadly lanceolate to oblong or obovate, (0–)3–5(–7)-lobed;

lobes ascending to erect, linear to lanceolate, short to medium length, arising above mid length, proximal bract apex acute, distal obtuse, rounded, or truncate.

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 to yellow, 1–2.5 mm.

slightly curved, 10–22 mm;

tube 8–14 mm;

teeth of abaxial lip sometimes slightly exserted, beak exserted or subequal;

beak adaxially green to pale yellow, 5–8 mm;

abaxial lip deep yellow or green, reduced, forming a small pouch visible through front cleft, 3–5 mm, 50–75% as long as beak;

teeth ascending to erect, white or yellow, 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.

colored as bracts, proximally often paler, usually yellow throughout, 10–20 mm;

abaxial and adaxial clefts 7–14 mm, 40–50% of calyx length, deeper than laterals, lateral 0.5–1.5 mm, 5–15% of calyx length;

lobes triangular, apex acute to rounded.
