Flora of North America species comparison

several to many, ascending to erect, often grayish, unbranched, rarely branched, sometimes with short, leafy axillary branches, hairs spreading-erect, long, stiff, eglandular, sometimes also with shorter, stipitate-glandular ones.

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

gray-green, linear, lanceolate, or oblanceolate, sometimes broadly lanceolate, (1.5–)2.5–6(–7) cm, not fleshy, margins plane, involute, (0–)3–5(–7)-lobed, sometimes with secondary lobes, apex acuminate to obtuse;

lobes spreading, linear, apex 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.

2.5–15 (much longer in fruit) × 1.5–5.5 cm;

bracts proximally greenish to dull purplish, distally bright red to scarlet or orange-red, rarely yellowish to dull orange or pink, narrowly to broadly linear or lanceolate, narrowly ovate, or oblong-lanceolate, (0–)3–7-lobed, rarely with secondary lobes;

lobes spreading, linear to oblong, sometimes oblanceolate, often expanded near tip, long, proximal lobes arising below mid length, apex rounded or obtuse to sometimes acute.

2–15 × 2–3 cm;

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

straight or ± curved, 18–35(–40) mm;

tube 8–15 mm;

beak short- or long-exserted, adaxially green to yellow-green, (9–)10–18 mm;

abaxial lip deep green, reduced, thickened, included to exserted, 2–3 mm, ca. 20% as long as beak;

teeth incurved, deep green, 0.5–1 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, sometimes with broad yellow band below colored lobe apices, (17–)20–27 mm;

abaxial clefts 4–10 mm, adaxial 6–12 mm, abaxial ca. 30% of calyx length, adaxial ca. 40% of calyx length, deeper than laterals, lateral 1–4 mm, ca. 15% of calyx length;

lobes oblong or ovate to narrowly triangular or lanceolate, apex obtuse to rounded.

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.
