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.

several, decumbent, often sprawling, distally ascending, unbranched unless injured, rarely with small, leafy axillary shoots, hairs spreading, whitish, short, ± stiff, 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.

gray-green, sometimes green or reddish purple, reduced and scalelike on proximal 10–25% of stem, linear, lanceolate, or narrowly elliptic, 1.5–4(–5) cm, not fleshy, margins plane, flat or involute, 0–3(–5)-lobed, apex acute;

lobes spreading or spreading-ascending, linear or 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.

2.5–10 × 2.5–5 cm;

bracts proximally green to deep greenish purple, distally bright red, sometimes brick red or orange-red, linear to lanceolate, 3–5(–7)-lobed;

lobes spreading, linear-lanceolate to lanceolate, sometimes expanded near tip, long, arising near base and more distally, apex acute to 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.

straight or slightly curved, 25–40(–45) mm;

tube 11–24 mm;

beak exserted, adaxially green to yellow, 10–17(–20) mm;

abaxial lip green, reduced, visible through front cleft, 1.5–2.5 mm, 10–15% as long as beak;

teeth incurved, green, 0.5–1 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.

colored as bracts, 18–33 mm;

abaxial clefts 6–12 mm, adaxial 8–15 mm, clefts 40–60% of calyx length, deeper than laterals, lateral 2–6 mm, 15–25% of calyx length;

lobes lanceolate or narrowly triangular, apex acute to acuminate.
