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, decumbent to ascending, unbranched except for small, leafy axillary shoots, hairs retrorse, short proximally, spreading, longer distally, soft, 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.

green to blackish, proximalmost small and scalelike, linear to narrowly or broadly lanceolate, 1–3(–4) cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex obtuse to rounded;

lobes ascending, linear or short-lanceolate, very small, apex acute to obtuse.

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.

4–6.5 × 1–3 cm;

bracts proximally greenish to deep purple near base, distally magenta, deep pink, or red, broadly lanceolate to elliptic, oblong, or ovate, 0–5-lobed;

lobes ascending to erect, triangular to oblong, short, arising near apex, central lobe apex rounded, lateral ones acute to rounded.

0–5 mm.

slightly curved, 20–48 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);

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.

colored as bracts, 12–18 mm;

abaxial and adaxial clefts 5.5–8.5(–10) mm, ca. 50% of calyx length, deeper than laterals, lateral 1–3(–5) mm, ca. 25% of calyx length;
