Flora of North America species comparison

few to several, erect to ascending, decumbent at base, unbranched except for small, leafy axillary shoots, hairs weakly spreading to appressed, ± matted, especially distally on stem, fairly short and sparse proximally, longer and denser distally, soft, eglandular, becoming woolly, often obscuring surface.

solitary or few to many, erect, unbranched to much-branched, glabrous or hairy proximally and/or distally, hairs sparse to dense, spreading to erect, short to fairly long, soft, eglandular.

gray with hairs, surface green to purple, linear to narrowly lanceolate, 1–3.8 cm, not fleshy, margins plane, sometimes ± wavy, involute, 0–3-lobed, apex acute;

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

green, narrowly lanceolate to linear-lanceolate, linear, or narrowly elliptic, 2–8 cm, not fleshy, margins plane, sometimes ± wavy, flat or involute, 0(–5)-lobed, apex acuminate;

lobes widely spreading, linear to narrowly lanceolate, apex acute.

2.5–6 × 1–2.5 cm;

bracts greenish to pale yellow-green or very pale, dull purplish throughout, lanceolate to oblong, (0–)3(–5)-lobed;

lobes usually ascending, linear, medium length to long, arising near mid length, apex acute.

3–16 × 2–3.5 cm;

bracts proximally greenish, distally red to orange-red, sometimes with a purplish medial band, lanceolate to broadly lanceolate or ovate in outline, (0–)3–5(–7)-lobed, sometimes also with 4 small teeth;

lobes ascending, linear-lanceolate, long, arising above or below mid length, apex acuminate, acute, or obtuse.

straight, 18–25 mm;

tube 3.5–5.5 mm; subequal to calyx, or beak and sometimes abaxial lip exserted;

beak adaxially yellow, 6–8 mm, hairs moderately long, matted on midline, very short-glandular on sides;

abaxial lip green, inconspicuous, slightly pouched, 3.5–5.5 mm, 60–90% as long as beak;

teeth erect, white or yellow, 0.5–3 mm.

slightly to moderately curved distally, 25–37 mm;

tube 16–20 mm;

beak exserted 10–16 mm beyond calyx, adaxially green to yellowish, 11–25 mm;

abaxial lip green or red, small, inconspicuous, visible through cleft of calyx, 2 mm, 15–20% as long as beak;

teeth incurved, green or red, 0.7–1.5 mm.

yellow, color mostly obscured by whitish hairs, 15–22 mm;

abaxial, adaxial, and lateral clefts (5.5–)7–12 mm, 35–55% of calyx length, often appearing shorter because matted hairs stitch proximal part of clefts shut, all 4 clefts subequal;

lobes broadly linear, apex acute.

proximally green, distally red, 20–25 mm;

abaxial clefts 11–14(–17) mm, adaxial 8–9 mm, abaxial 50–60% of calyx length, adaxial 35–40% of calyx length, deeper than laterals, lateral 5–7 mm, 10–15% of calyx length;

lobes lanceolate to narrowly triangular, apex acute to acuminate.
