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, erect, unbranched, sometimes branched, glabrous or hairs sparse proximally, spreading, long, soft distally.

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 purple-tinged, linear to narrowly lanceolate, (0.4–)1–4 cm, not fleshy, thin and flexible or thick and ± brittle, margins plane, involute, 0-lobed, apex acuminate.

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.

2–15 × 2–3 cm;

bracts green throughout, sometimes purplish tinged, linear to narrowly lanceolate, 0-lobed, apex acute.

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, 11–26 mm;

tube 10–22 mm;

abaxial lip, beak, and part of tube exserted from calyx;

beak adaxially white or yellow, 3–6 mm;

abaxial lip yellow, sometimes orange, paler near teeth, prominent, deeply saccate with 3 lobes at ca. 90° from one another, pouches 6–10 mm wide, 3–4 mm deep, abruptly widening from tube, sacs ± round or ± rounded-triangular from above, villous within at base of teeth, 4–5 mm (2–4 mm from sinus), 70–90% as long as beak, puberulent;

teeth erect, white, sometimes with deeply colored bases, 0.5–2 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.

proximally green, pale, or purplish, distally purple or green, 5.5–11 mm;

abaxial and adaxial clefts 2–5 mm, 30–50% of calyx length, deeper than laterals, lateral 1.5–2.5 mm, 25–30% of calyx length;

lobes linear-lanceolate to narrowly triangular, apex acute to acuminate.
