Flora of North America species comparison

several to many, ascending to erect, often grayish, unbranched, rarely branched, sometimes with short, leafy axillary branches, hairs spreading-erect, long, stiff, eglandular, sometimes also with shorter, stipitate-glandular ones.

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.

gray-green, linear, lanceolate, or oblanceolate, sometimes broadly lanceolate, (1.5–)2.5–6(–7) cm, not fleshy, margins plane, involute, (0–)3–5(–7)-lobed, sometimes with secondary lobes, apex acuminate to obtuse;

lobes spreading, linear, apex 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.

2.5–15 (much longer in fruit) × 1.5–5.5 cm;

bracts proximally greenish to dull purplish, distally bright red to scarlet or orange-red, rarely yellowish to dull orange or pink, narrowly to broadly linear or lanceolate, narrowly ovate, or oblong-lanceolate, (0–)3–7-lobed, rarely with secondary lobes;

lobes spreading, linear to oblong, sometimes oblanceolate, often expanded near tip, long, proximal lobes arising below mid length, apex rounded or obtuse to sometimes acute.

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 or ± curved, 18–35(–40) mm;

tube 8–15 mm;

beak short- or long-exserted, adaxially green to yellow-green, (9–)10–18 mm;

abaxial lip deep green, reduced, thickened, included to exserted, 2–3 mm, ca. 20% as long as beak;

teeth incurved, deep green, 0.5–1 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, sometimes with broad yellow band below colored lobe apices, (17–)20–27 mm;

abaxial clefts 4–10 mm, adaxial 6–12 mm, abaxial ca. 30% of calyx length, adaxial ca. 40% of calyx length, deeper than laterals, lateral 1–4 mm, ca. 15% of calyx length;

lobes oblong or ovate to narrowly triangular or lanceolate, apex obtuse to 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.
