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.

few to many, ascending to erect, unbranched or often strongly and diffusely branched distally, hairs sparse to dense, spreading to matted, long proximally on stem, becoming puberulent distally, ± stiff, eglandular, often mixed with retrorse shorter 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, linear-lanceolate or narrowly to broadly lanceolate, 2–6.5(–8) cm, not fleshy, margins plane, flat to involute, 0(–3)-lobed, apex acute;

lobes ascending, lanceolate, apex acute to obtuse.

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.

(2.5–)5–15 × 2–4.5 cm;

bracts proximally greenish, distally scarlet to red or orange-red, rarely yellow or crimson, veins usually yellow or yellow-green, contrasting conspicuously with base color, lanceolate or elliptic to oblanceolate or obovate, 0–3(–5)-lobed;

lobes ascending, lanceolate to triangular, medium length, arising above mid length, apex rounded to obtuse.

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.

slightly curved, 15–35 mm, subequal to calyx or beak partially to strongly exserted;

tube 15–17 mm;

beak adaxially yellowish green, 10–16 mm;

abaxial lip green, reduced, ± pouched, 0.5–1.5 mm, 4–10% as long as beak;

teeth incurved, deep green, 0.7–1 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.

mostly yellowish throughout, with a thin reddish apex, 15–27 mm;

abaxial clefts (5–)9–11 mm, adaxial 4.5–9.5 mm, clefts 25–50% of calyx length, deeper than laterals, lateral 2–4 mm, 10–20% of calyx length;
