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 many, erect to basally ascending, sometimes with subtle, curvy zigzags, unbranched, sometimes branched, proximally or with short, leafy axillary shoots, hairs loosely spreading, long, soft, ± wavy, eglandular and shorter stipitate-glandular.

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.

green, linear-oblong to oblong-lanceolate, narrowly lanceolate, or narrowly oblanceolate, 2–5.5 cm, not fleshy, margins plane, involute, 0-lobed, apex acute, distalmost obtuse to rounded.

(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.

2–7.5 × 2–3.5 cm;

bracts proximally greenish, distally abruptly rose red, bright red, or red-orange, narrowly to broadly oblong-obovate to obovate or ovate-elliptic, 0-lobed;

apex rounded to obtuse.

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;

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, sometimes with a yellow central band, 20–32(–36) mm;

abaxial and adaxial clefts (5–)7–14 mm, ca. 40% of calyx length, deeper than laterals, lateral 0–0.5 mm, 0–7% of calyx length;
