Flora of North America species comparison

solitary, erect to ascending, unbranched, sometimes branched from base, hairs spreading, short and medium, ± stiff, eglandular.

few to many, erect or ascending, much-branched with many short, leafy axillary shoots, hairs recurved to retrorse, short, ± stiff, eglandular, often with some spreading, long ones.

green to purple-tinged, linear to linear-lanceolate, (1–)2–8 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate;

lobes spreading to ascending, filiform to lanceolate, apex sometimes acuminate.

green, linear-lanceolate to lanceolate, 1–3.5 cm, not fleshy, margins plane, sometimes ± wavy, flat to involute, (0–)3–7-lobed, apex acute to obtuse;

lateral lobes spreading, linear, much shorter and narrower than terminal lobe, apex acute.

(1.5–)2–10(–19, –30 in fruit) × 1–2 cm;

bracts proximally green to pale brown, rarely dull reddish brown, distally white on apices, sometimes pale yellow or pale pink-purplish on apices, rarely greenish or dull reddish brown throughout, lanceolate or lanceolate-elliptic, 3(–5)-lobed;

lobes ascending, linear to lanceolate, long, arising below mid length, apex acuminate, acute, or obtuse.

3–17 × 2–7.5 cm;

bracts green throughout, sometimes distalmost proximally green, distally red or red-orange on apices, lanceolate or broadly lanceolate, (0–)3–5-lobed;

lobes spreading, linear or narrowly lanceolate, short, arising near or below mid length, central lobe apex obtuse to rounded, lateral ones acute.

straight, 10–25 mm;

tube 9–20 mm, not expanded distally;

beak exserted, straight, adaxially white, light yellow, or greenish, 3–5 mm, inconspicuously puberulent;

abaxial lip white or yellow with deep brown to purple spots, often becoming pink, slightly inflated, exserted or not, pouches 3, 2 mm wide, 1–1.5 mm deep, 3–4 mm, 75–80% as long as beak;

teeth erect, white, pale yellow, or pink, 0.5–1.2 mm.

slightly curved, (24–)27–43 mm;

tube 9–20 mm;

beak longer than calyx, exserted through abaxial cleft, adaxially green to yellowish, 22–39 mm;

abaxial lip deep green, inflated, tight, 1–2.5 mm, 5–10% as long as beak;

teeth often spreading, green or white, 0.5–1.6 mm.

colored as bracts, (8–)15–23 mm;

abaxial and adaxial clefts (4–)6–8 mm, abaxial ca. 50% of calyx length, adaxial ca. 75% of calyx length, lateral 3–3.5 mm, 33% of calyx length;

lobes linear to narrowly triangular, apex acute to acuminate.

proximal 1/3 green, distal 2/3 red to pale red-orange, rarely yellow, (17–)25–35(–40) mm;

abaxial clefts 14–29 mm, 67–75% of calyx length, adaxial 2.5–7.3 mm, 5–15% of calyx length, deeper than laterals, lateral 0–0.3(–2) mm, 0–5% of calyx length;

lobes broadly triangular, entire or shallowly cleft, segments, if present, often differing in length, apex acute, obtuse, or rounded.

glabrous.
