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 or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly.

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 to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;

lobes divergent, spreading-ascending, linear, apex acute to acuminate.

(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.

5–22 × 1–4.5 cm;

bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;

lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.

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.

straight or slightly curved, 14–22 mm;

tube 7–14 mm;

beak tip barely exserted from calyx;

beak adaxially greenish, 4–7 mm;

abaxial lip green to yellow, reduced, 1–4 mm, usually less than 67% as long as beak;

teeth erect, white to yellow, 1–2.5 mm.

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;

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

colored as bracts, 15–20 mm;

abaxial and adaxial clefts 5.5–8 mm, 30–50% of calyx length, ± deeper than laterals, sometimes appearing subequal in pressed specimens, lateral 5–6 mm, ca. 33% of calyx length;

lobes linear to narrowly lanceolate, sometimes expanded towards apices, apex acute.
