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.

few to many, erect or ascending, often branched distally, sometimes unbranched, sometimes with short axillary shoots, proximal hairs retrorse to appressed, short to moderately long, distal hairs spreading, longer, soft, often mixed with short stipitate-glandular ones.

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, linear-lanceolate, rarely broadly lanceolate, (1.2–)2.5–8(–9) cm, not fleshy, margins plane, flat or involute, 0(–3)-lobed, apex acute to rounded;

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

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–)4–17 × 1.5–3 cm;

bracts proximally greenish, distally red, orange-red, or orange, proximal sometimes lanceolate, distal broadly lanceolate to ovate, (0–)3(–7)-lobed;

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

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, 23–30(–35) mm;

tube 12–20 mm;

beak exserted, adaxially green, 8–12(–14) mm;

abaxial lip pale to deep green, reduced, rounded, 0.5–1.5 mm, 10–20% as long as beak;

teeth erect to incurved, green, (0.4–)0.7–1.2(–2) 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 pale yellow or greenish, distally colored as bracts, (15–)18–28 mm;

abaxial and adaxial clefts 6–12 mm, 40–45% of calyx length, deeper than laterals, lateral 2.5–8 mm, 20–30% of calyx length;

lobes linear to narrowly lanceolate, apex acute to acuminate.
