Flora of North America species comparison

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.

few to several, decumbent to erect, sometimes leaning, unbranched or often much-branched distally, with a few short, leafy axillary shoots, hairs spreading, short, soft, stipitate-glandular, mixed with long-spreading, eglandular ones.

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.

gray-green, sometimes green, lanceolate-linear to narrowly lanceolate, 1–6.5 cm, not fleshy, margins plane, sometimes wavy, flat to involute, 0(–3)-lobed, apex acuminate;

lobes spreading-ascending, linear to narrowly lanceolate, apex 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.

3–30 × 3–4 cm;

bracts proximally green to dark purplish, distally red to crimson, sometimes pale salmon, linear-lanceolate to broadly lanceolate, 3–5-lobed;

lobes spreading, linear, long, arising below mid length, apex acute, sometimes obtuse.

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;

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;

lobes linear-lanceolate to triangular, apex acute to acuminate, rarely ± obtuse.

colored as bracts, 15–20 mm;
