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 decumbent at base, unbranched, sometimes branched, hairs spreading, long, soft, mixed with dense, shorter 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 or purple-tinged, sometimes deep purple, broadly lanceolate, sometimes linear-lanceolate or narrowly oblong, 1.5–4.8 cm, not fleshy, margins plane, flat or involute, 0–3-lobed, apex acute;

lobes ascending or spreading, linear to narrowly linear or narrowly lanceolate, short, apex acuminate.

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.

3–17 × 1–3 cm;

bracts greenish or pale yellow-green throughout, or proximally greenish or pale yellow-green, distally pale yellow to whitish, sometimes pink-purple, or pale, dull purplish, sometimes aging pink or yellow, often infused with light purple, rarely pink, ovate to broadly acute, (0–)3-lobed;

lobes ascending, linear-lanceolate, oblong, or triangular, short, arising below mid length, 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, (16–)20–25 mm;

tube 15–18 mm;

beak slightly exserted, adaxially green to yellow, 5.5–8.5 mm;

abaxial lip white, green and white, pink, or purple, ± prominent, appressed (proximally scarcely or not pouched), 3–5 mm, 67% as long as beak;

teeth erect, white or pink with some purple or red, 1.5–2.5 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, pale with green veins, purple-tinged green, or purple, distally pale yellow, white, or purplish, 12–20 mm;

abaxial and adaxial clefts 8–12 mm, 50% of calyx length, deeper than laterals, lateral 0.5–3 mm, 5–15% of calyx length;

lobes short-triangular, apex obtuse, rounded, or truncate.
