Flora of North America species comparison

few to many, decumbent-based to erect, unbranched except for short, leafy axillary shoots, hairs sparse, spreading, medium length to long, soft and dense, short to medium length, stipitate-glandular.

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 or gray-green to purple (sometimes different on stems of same plant), linear-lanceolate, distal sometimes broadly lanceolate, 0.5–4 cm, not fleshy, margins plane, involute, 0(–3)-lobed, apex acute to acuminate;

lobes ascending, linear to narrowly lanceolate, apex acute to acuminate, rarely obtuse.

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.

2–12 × 1–3 cm;

bracts greenish to dull purplish or brownish throughout, or proximally greenish to dull purplish, distally pink to purple or magenta, rarely white, ovate, broadly lanceolate, or oblong, (0–)3–5-lobed;

lobes ascending to erect, lanceolate, medium length, arising above mid length, apex acute to rounded.

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.

slightly curved, 16–21 mm;

tube 10–16 mm;

abaxial lip sometimes partly exserted, beak usually exserted;

beak adaxially green, 6–7 mm, margins red;

abaxial lip greenish, inflated, pouches 3, shallow, central pouch shallowly grooved, visible through front cleft, 3–4 mm, 60% as long as beak;

teeth erect, violet-purple or pink, 1–2.5 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.

proximally brown or dull magenta, sometimes green, distally colored as bracts, 12.5–18 mm;

abaxial and adaxial clefts 5.5–10.5 mm, 40–65% of calyx length, deeper than laterals, lateral 0.5–2 mm, 5–15% of calyx length;

lobes oblong, apex rounded.

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.
