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.

several, erect or ascending, unbranched, sometimes branched, hairs sparse, spreading or retrorse, moderately long, soft, crisped, eglandular, mixed with shorter 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, brown, or purple, linear to lanceolate, 1.5–6 cm, not fleshy, margins plane, rarely ± wavy, involute, 3–5(–7)-lobed, apex acuminate to acute;

lobes widely spreading, deep, linear to narrowly lanceolate, lateral lobes not much narrower than central one, 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.

3–22 (longer in fruit) × 1–5 cm;

bracts proximally greenish to deep purplish, distally bright red or scarlet, sometimes orange to pale yellow, linear, (3–)5–7-lobed, sometimes with secondary lobes;

lobes spreading, linear to oblanceolate, long, arising 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 to yellow, 1–2.5 mm.

straight, 20–35 mm;

tube 13–23 mm;

beak and usually part of abaxial lip exserted;

beak adaxially green, 6.9–13 mm;

abaxial lip deep green, reduced, thickened, included or visible through front calyx cleft, 1.7–3.8 mm, 10–25% as long as beak;

teeth incurved, yellow or deep green, 0.7–1.7 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, sometimes paler proximally, 15–26(–33) mm;

abaxial clefts 4–7.4 mm, adaxial 7–10 mm, abaxial 21–37% of calyx length, adaxial 28–51% of calyx length, deeper than laterals, lateral 1.5–3.5(–5) mm, 8–18% of calyx length;

lobes lanceolate to triangular, apex acute.
