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, erect, unbranched, sometimes branched, hairs spreading, short, soft, often mixed with stipitate-glandular ones.

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 purple-tinged or dark red-brown, linear-lanceolate or distal lanceolate, 2–8(–9) cm, not fleshy, margins plane, flat to slightly curved up, 0–7-lobed, apex acute to acuminate;

lobes widely spreading or ascending-spreading, linear, apex 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.

2.5–24 × 3–4 cm;

bracts green throughout, lanceolate to ovate, 5–9-lobed;

lobes ascending, linear-lanceolate or lanceolate, medium length, arising near mid length, apex acute to acuminate.

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.

straight, (15–)20–28 mm;

tube 8–24 mm;

abaxial lip, beak, and proximal part of corolla tube exserted;

beak adaxially white, rarely very pale yellow or pale pink-purple, 5–7 mm, inconspicuously puberulent;

abaxial lip white, fading to pink to pink-purple, or yellow, fading to white, rarely then to pink or pink-purple, both forms often with purple or red dots at base, inflated, prominent, pouches 3, 8–10 mm wide, 4–6 mm deep, 4–6 mm, 80–100% as long as beak;

teeth erect, white or yellow, 0.5 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, 8–14 mm;

abaxial and adaxial clefts 3–6 mm, 30–50% of calyx length, all 4 clefts subequal;

lobes linear, apex acuminate to acute.

± exserted, as long as or slightly longer than beak and visible from abaxial side.
