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 to many, erect or ascending, sometimes curved at base, unbranched or branched, sometimes with short, leafy axillary shoots, hairs spreading, short or long and distally short, stiff or soft, stipitate-glandular.

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 to sometimes purple, narrowly oblong or lanceolate to sometimes linear or narrowly ovate, (0.8–)1–5(–6.5) cm, not fleshy, margins wavy, flat or involute, 0–5-lobed, apex rounded or obtuse, rarely acute;

lobes ascending-spreading or divaricate, linear to narrowly oblong, 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.

2.5–25 × 1.5–4 cm;

bracts proximally greenish, distally red, orange-red, or pale orange, rarely yellow, lanceolate or broadly lanceolate to oblong, (0–)3–5(–7)-lobed, plus 1–3 shallow teeth on apex of central lobe (var. clokeyi);

lobes ascending or spreading, linear, lanceolate, or oblanceolate, medium length or long, arising at or near mid length, central lobe apex obtuse to 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 to slightly curved, (19–)22–45 mm;

tube 11–22 mm;

abaxial lip rarely exserted, beak exserted;

beak adaxially green to yellowish, 9–21(–23) mm;

abaxial lip green or deep green with white teeth or red with green teeth, reduced, not inflated, often visible through front cleft, 1–2 mm, ca. 10% as long as beak;

teeth incurved, green to white, 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.

proximally pale green, green, or whitish, sometimes with a yellow central band, distally colored as bracts, 14–26(–28) mm;

abaxial and adaxial clefts 3–10 mm, 20–50% of calyx length, deeper than laterals, lateral 1–5 mm, 15–20% of calyx length;

lobes lanceolate to broadly lanceolate, oblong, or ovate, apex acute, obtuse, or rounded.
