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.

glabrous or sparsely hairy proximally and medially, subglabrous or sparsely hairy distally, hairs spreading, short to long, soft, eglandular, rarely stipitate-glandular.

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.

spreading to ascending, linear to lanceolate, narrowly elliptic, or narrowly oblong, thin and not fleshy, margins plane, rarely wavy, flat to slightly involute, leaf sometimes recurved downward, 0(–3)-lobed, apex acute to acuminate, sometimes obtuse.

distally scarlet, red, orange-red, or pale orange, sometimes pink, pink-purple, magenta, pale orange, yellow, greenish yellow, or white, 0–3(–5)-lobed, central lobe with 3–5 small teeth at apex;

central lobe apex obtuse, rounded to truncate, lateral ones acute to rounded.

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.

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;

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.

20–48 mm;

beak 9–25 mm;

abaxial lip deep green or deep purple, 0.5–3.5 mm, 10–15% as long as beak, to ca. 33% as long as beak in some populations.

colored as bracts, 15–38 mm;

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

15–36 mm;

abaxial and adaxial clefts 8–20 mm, ca. 40% of calyx length, subequal or abaxial longer, lateral 1–9 mm, 15–20% of calyx length;

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