Flora of North America species comparison

few to many, erect to ascending, rarely proximally decumbent or creeping and rooting at nodes, usually branched, glabrous, glabrate, or hairy, hairs spreading to ± retrorse, short to long, soft to stiff, rarely stipitate-glandular.

several to many, erect or ascending, often grayish, unbranched or often branched distally, glabrate proximally or hairy, especially distally, rarely glabrous, hairs sparse, spreading to appressed, usually curly, ± short, soft, sometimes mixed with sparse, short stipitate-glandular ones.

green to purple, linear to lanceolate, narrowly elliptic, narrowly oblong, or ovate, (1.5–)3–8(–9.5) cm, thin and not fleshy or slightly to moderately thickened and slightly fleshy, margins plane, rarely wavy, flat to involute, whole leaf sometimes recurved downward, 0(–5)-lobed, apex acute to obtuse, sometimes rounded;

lobes ascending-spreading, narrowly lanceolate, apex acute.

often grayish or purplish, linear to narrowly lanceolate or narrowly oblong, (1–)2.5–5(–6.7) cm, not fleshy, margins plane or wavy, involute, deeply (0–)3–5(–7)-lobed, apex acute to acuminate;

lobes divaricate to spreading or ascending, linear, arising at or below mid length, apex acute to acuminate.

3–15(–22) × 1.5–5.5 cm, often bearing a thin, white, powdery exudate, especially on bract surfaces;

bracts greenish, scarlet, red, red-orange, or pale orange throughout, sometimes pink, magenta, pink-purple, yellow, greenish yellow, white, or salmon throughout, or proximally greenish, distally colored as above, lanceolate to oblong-ovate, 0–5(–7)-lobed, central lobes sometimes distally apiculate;

lobes erect, linear to lanceolate, oblong, or oblanceolate, short or medium length, arising near or above mid length, central lobe apex obtuse, rounded, or truncate, lateral ones rounded to acute or acuminate.

3.5–20(–29) × 1–4 cm;

bracts pale green to pale yellow throughout, or proximally pale green to pale yellow, distally pale yellow to bright yellow, sometimes light orange, light red, or bright red, lanceolate to narrowly oblong or narrowly elliptic, slightly broader than leaves, usually 3–5-lobed;

lobes ± spreading, linear or narrowly lanceolate, short or long, proximal or all bracts arising near or below mid length, apex acute, sometimes narrowly obtuse.

0–5 mm.

slightly curved, 20–48 mm;

tube 12–26 mm;

abaxial lip usually not exserted, though often visible in front calyx cleft, beak partially to fully exserted;

beak adaxially green to yellow-green or whitish, (9–)14–25 mm;

abaxial lip incurved or ascending, deep green or green, sometimes deep purple or yellowish, reduced, not inflated, visible in front cleft, 0.5–3.5 mm, 5–20% as long as beak (to ca. 33% as long as beak in some populations of var. miniata);

teeth incurved or erect, green or white, 0.7–1.5 mm.

straight or ± curved, 13–30 mm;

tube 12–16 mm;

beak, sometimes abaxial lip, slightly to strongly exserted, corolla often curved and exserted through abaxial cleft;

beak adaxially green, (5–)6–12 mm;

abaxial lip green or yellow, reduced, exserted or more commonly visible in cleft in calyx, 1–3.5 mm, 20–33(–50)% as long as beak;

teeth ascending, green to yellow, 0.5–2 mm.

colored as bracts, 15–38 mm;

abaxial and adaxial clefts 4–24 mm, 35–70% of calyx length, deeper than laterals, lateral (1–)3–8(–12) mm, 5–30% of calyx length;

lobes linear or narrowly lanceolate to narrowly triangular, apex acute to acuminate or obtuse.

proximally green, sometimes purple or pinkish, distally yellow to light orange, dull green, or colored as bracts, 11–28 mm;

abaxial and adaxial clefts 4–16(–17) mm, 30–60(–95)% of calyx length, deeper than laterals, lateral 0.5–7 mm, 4–30% of calyx length;

lobes linear to lanceolate or narrowly to broadly triangular, apex acute to acuminate.
