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 or 1–4 branches from proximal 1/2, hairs spreading, long, soft, often mixed with shorter stipitate-glandular ones.

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, not forming a distinct basal rosette, sometimes relatively dense proximally with short internodes, similar in size and shape to more distal cauline leaves, narrowly lanceolate to linear-lanceolate, (1.5–)2–8(–9) cm, not fleshy, margins wavy, sometimes plane, involute, 0(–5)-lobed, apex acute;

lobes erect, linear or filiform to narrowly lanceolate, apex acute to 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.

2–16(–20) × 3–5.5 cm;

bracts proximally greenish, distally scarlet or bright red, sometimes deep to pale pink, peach, yellow, white, or magenta, sometimes with a white to rarely yellow medial band between green and brightly colored distal portion, proximal narrowly lanceolate, distal shorter and oblong-obovate, broadly obovate, or obtrullate, 0(–5)-lobed;

lobes erect or ascending, triangular, short, arising above mid length, proximal bract apex acute, distal obtuse, rounded, or truncate.

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.

curved in proximal 1/3, 15–29 mm;

tube 2–3.5 mm;

whole corolla included or beak partly exserted, abaxial lip included;

beak adaxially green, yellow, or pink, 4–10 mm;

abaxial lip green, white, or yellow, reduced, pouches 3, 2 mm, 25–30% as long as beak;

teeth erect, green, white, or yellow, 0.5 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 light green, distally red, pale pink, or white, rarely pale yellow, usually paler than bracts, often with a white to yellow medial band between green and brightly colored distal portion, 16–31 mm;

abaxial and adaxial clefts 6–10 mm, 25–33% of calyx length, deeper than laterals, lateral 0(–0.2) mm, 0(–4)% of calyx length;

lobes expanded distally, apices much wider than narrow calyx tube, apex rounded, truncate, or emarginate.
