Flora of North America species comparison

few to many, usually decumbent proximally, becoming ascending-erect, sometimes ascending, branched, sometimes with small, leafy axillary shoots, glabrate or ± pubescent distally, hairs sparse to moderately dense, spreading to ± appressed, short, soft, sometimes mixed with short-glandular ones below inflorescence.

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.

green, lanceolate to oblong or narrowly ovate, (0.5–)3–8 cm, sometimes thickened, not fleshy, margins plane, sometimes ± wavy, flat to involute, 0(–3)-lobed, apex acute to rounded;

lobes ascending or spreading, linear, narrowly lanceolate to oblong or triangular, short, apex acute to obtuse.

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.

2.5–21 × 3–5 cm;

bracts proximally green, distally bright red to crimson or orange-red, sometimes orange or pale yellow-orange, oblong to narrowly ovate or narrowly obovate, (0–)3–5-lobed, sometimes with a pair of small teeth;

lobes ascending, linear to oblong, medium length, arising in middle 1/3, central lobe apex obtuse to rounded or truncate, lateral ones ± acute.

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.

0–6 mm.

straight or slightly curved, 23–38(–40) mm;

tube 10–20 mm;

abaxial lip often visible through front cleft, very rarely almost exserted, beak exserted;

beak adaxially green or yellowish, 10–16 mm, surface inconspicuously puberulent;

abaxial lip ascending, green, reduced, 1–2.5 mm, 10–20% as long as beak;

colored as bracts, 17–25(–30) mm;

abaxial and adaxial clefts (5–)7–15(–18) mm, 33–55% of calyx length, deeper than laterals, lateral 1–3(–5) mm, 5–10% of calyx length;

lobes broadly triangular to oblong, apex obtuse to acute or rounded.

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.
