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.

few to several, erect or ascending, unbranched, sometimes branched, hairs dense distally, less so proximally, spreading, long, soft, eglandular, also mixed with short stipitate-glandular ones distally.

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.

green to purple, narrowly to broadly lanceolate to oblong, (0.7–)1.5–4.2(–5) cm, not fleshy, margins plane, flat or involute, (0–)3(–5)-lobed, apex acuminate;

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

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.

2.5–7.5(–15) × 1.5–3 cm;

bracts proximally greenish to dull reddish, distally bright red, orange, or pale orange, sometimes yellowish or dull red, broadly lanceolate to oblong, 3–5-lobed;

lobes ascending, linear to lanceolate, ± long, arising above mid length, sometimes below mid length on proximal bracts, central lobe apex acute, rarely narrowly obtuse, lateral ones acute.

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);

slightly curved, 15–28 mm;

tube 13–15 mm;

beak exserted, adaxially yellow or yellow-green, 7–8 mm;

teeth erect or curved, yellow or green, 0.7–1 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 light green or yellow, distally yellow or colored as bracts, 12–20 mm;

abaxial and adaxial clefts 5–9 mm, 40–50% of calyx length, deeper than laterals, lateral (1.5–)3–5.8 mm, 10–30% of calyx length;

lobes oblong, apex acute to obtuse.
